DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 TUESDAY *** Poor to Marginal Smoke Dispersal Conditions *** A strong high pressure area will be centered over Las Vegas, Nevada on Tuesday while a major trough develops about 1000 miles to the west in the Gulf of Alaska and eastern Pacific Ocean. Upper flow over the area will be west-southwest with very stable conditions developing. Expect dry weather and decreasing clouds. Mixing heights will be suppressed and transport winds will be mostly light north or northeasterly. EXTENDED OUTLOOK (WEDNESDAY - FRIDAY) *** Poor to Marginal Ventilation Conditions Through the Week *** By Wednesday the upper high looses strength and drifts east. Flow aloft backs to southwest. Transport winds switch to southeast through east most areas. Maximum mixing heights remain low and nighttime inversions will hold any residual smoke close to the ground. The upper ridge re-strengthens on Thursday for continued low maximum mixing heights and unfavorable ventilation conditions. A weakening front brings some light rain to much of the region Friday but maximum mixing heights remain fairly low. Transport winds become generally west through southwest. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY *** Poor to Marginal Smoke Dispersal Conditions *** Upper air charts show a broad ridge with its axis stretching from Arizona northward to Alberta and a broad trough in the Gulf of Alaska and the eastern Pacific about 900 miles west of the coast. Upper flow over Oregon is southwesterly. Temperatures at about 5000 feet above sea level will be running about 20F warmer than average for this time of year. The warm air aloft will make the atmosphere very stable for unfavorable smoke dispersal conditions. Transport winds will be generally from east or southeast (except more southerly in southern zones) and light, while mixing heights will be quite low. EXTENDED OUTLOOK (THURSDAY - SATURDAY) *** Poor to Marginal Ventilation Continues Thursday *** The upper level pattern slowly shifts east with little improvement for Thursday. By Friday the upper trough approaches from the west and temperatures aloft will be much cooler helping to improve ventilation. Mixing heights will be higher on Friday, but transport winds will shift from offshore to onshore during the day. The shifting wind pattern is difficult to time precisely and we recommend against planning any units close in to SSRA's due to the uncertainty of wind directions. A weakening Pacific front reaches the area late in the day for some light rain spreading eastward. A second front brings another surge of rain Saturday and transport winds will shift to strong southerly. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 THURSDAY *** Poor to Marginal Smoke Dispersal Conditions Continue *** Thursday's upper air pattern will be very similar to Wednesday's - just shifted slightly eastward. Upper flow over the region will be from the southwest. Low level flow, however, will be transitioning from offshore to onshore during the day. Shifting transport winds will make burning close to SSRA's problematical. Expect mixing heights generally between 1500 and 2000 feet and transport winds light south or southeast turning to west or northwest during the afternoon. EXTENDED OUTLOOK (FRIDAY - SUNDAY) On Friday an upper level trough approaches from the west. Associated cooler air aloft should allow for higher maximum mixing heights for improved ventilation conditions. A weakening surface front associated with the trough reaches the coast by evening for some light rain Friday night. The upper trough moves through early Saturday and there will be some stabilization during the mid part of the day. However another relatively weak front will brings more rain during the afternoon. Expect a few left-over showers Sunday, fair smoke dispersal conditions and transport winds mostly from the southwest. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 FRIDAY The massive upper-level ridge of high pressure that has been bringing the region record-breaking warmth and stagnant ventilation conditions will weaken and shift slightly eastward. The ridge axis is forecast to stretch from Utah through eastern Montana with a slowly strengthening southwesterly flow aloft over Oregon. The first in a series of progressively stronger weather systems will fall apart along the coastline, with little to no rain making it onshore. Transport winds will remain light. Surface temperatures will, once again, be unseasonably warm, but very warm air aloft will keep mixing heights low and make for marginal to poor smoke dispersal conditions. OUTLOOK (SATURDAY-MONDAY) The second in a series of weather systems will approach the coastline on Saturday, but it appears as if any significant rainfall will hold off until evening. Surface temperatures will stay well above normal. However, cooling aloft will raise afternoon mixing heights, with increasing south to southwesterly transport winds improving ventilation conditions. A cold front will likely spread rain across western Oregon by Saturday night, continuing through Sunday morning. Rainfall amounts should exceed one-quarter of an inch, with close to an inch possible at higher elevations. Surface temperatures will cool to near normal. Cooler air aloft will drop the snow level to around 3500 feet north and 4500 feet south, by evening, with good afternoon smoke dispersal conditions. Showers will continue through Sunday night. A flat and transitory upper-level ridge will being some drying on Monday and may suppress afternoon mixing heights slightly. Surface temperatures will cool to slightly below normal with a continued threat of showers. Transport winds will remain onshore with fair to good smoke dispersal conditions. 2.

However, cooling aloft will begin to raise afternoon mixing heights. Increasing south to southwesterly transport winds will also act to improve afternoon ventilation conditions. OUTLOOK (SUNDAY-TUESDAY) A cold front will spread rain across western Oregon Saturday night through Sunday morning. Rainfall amounts should exceed one-quarter of an inch, with close to an inch possible at higher elevations. Surface temperatures will cool to near normal. Cooler air aloft will provide good afternoon smoke dispersal conditions with the snow level dropping to near 3500 feet north and 4500 feet south by Sunday evening. Showers will continue into Monday, but a flat and transitory upper-level ridge will stabilize the air mass slightly during the day. Surface temperatures will cool to slightly below normal with snow levels near 3000 feet north and 4000 feet south. Transport winds will remain onshore with fair to good smoke dispersal conditions. The next weather system is forecast to move mainly into northern California and southern Oregon on Tuesday. That would keep snow levels around 3500 feet north and 4500 feet south. Transport winds will depend on the exact track of the low-pressure center but appear as if they may turn offshore across northern zones and southwesterly over southern zones. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 A cold front will spread rain across western Oregon in the morning. Rainfall amounts should exceed one-quarter of an inch, with close to an inch possible at higher elevations. Cool and unstable air will follow the cold front onshore, providing good afternoon smoke dispersal conditions and lowering snow levels to near 3500 feet north and 4500 feet south after dark. OUTLOOK (MONDAY-WEDNESDAY) Showers will continue Monday, but a flat and transitory upper-level ridge may slightly stabilize the air mass late in the day. Daytime highs will be 5-10 degrees below normal with a couple of inches of snow possible above 3000 feet north and 4000 feet south. Transport winds will remain onshore with fair to good smoke dispersal conditions. The next weather system will move onshore Tuesday afternoon. Previous computer model forecasts showed this system headed mainly into southern Oregon and northern California, but the latest guidance brings it more directly into western Oregon. That would still keep snow levels fairly low, around 3500 feet north and 4500 feet south, with more significant precipitation expected. The more northern forecast track, of this system, will likely bring a strong southerly component to the transport winds across all zones with fair to good smoke dispersal conditions. A transitory upper-level ridge will bring some drying on Wednesday and suppress mixing heights. 2. DISPERSION Zone 601-612 (North Coast Range and Cascades): MORNING Mixing height 3000 - 4000 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 MONDAY Upper troughiness over the Pacific Northwest will be moving east during the day and a broad, flat ridge will be approaching from the west. This will slowly stabilize the atmosphere but scattered showers will likely persist into the afternoon. Expect fair smoke dispersal conditions most areas. EXTENDED OUTLOOK (TUESDAY - THURSDAY) *** Deteriorating Smoke Dispersal Conditions after Tuesday *** An upper low moves rapidly across the eastern Pacific during the day on Tuesday. A surface cold front associated with this low will bring rain back to the region. The rain will reach the coast by early morning and spread eastward for a generally rainy day. Amounts will mostly be between a third and a half of an inch. The front and upper low move rapidly through the region and by Wednesday a strong ridge pops up to the west. Subsidence with this ridge will depress maximum mixing heights. The low mixing heights throughout the region and mostly light and variable winds in northern zones, will mean only limited burning opportunities. The upper ridge moves eastward across the region on Thursday with a weak Pacific cold front approaching the northwest corner of the state on Thursday. This will improve conditions a bit in northern zones, but southwest Oregon will continue to experience poor smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 TUESDAY A small, fast moving upper low moves across the southern Gulf of Alaska and into the Pacific Northwest on Tuesday. The low supports a Pacific cold front which will bring rain to the region much of the day. Precipitation amounts will range from near two-thirds of an inch in the north to about one-third of an inch or less in the south. The snow level will be near 3500 feet in the north and 4000 feet in the south following frontal passage. Expect southwest to south transport winds. EXTENDED OUTLOOK (WEDNESDAY - FRIDAY) *** Marginal Ventilation Conditions Wednesday *** The upper low moves rapidly east and the atmosphere becomes increasingly stable as an upper ridge builds over the eastern Pacific. Light and variable winds, together with low mixing heights by afternoon, mean few burning opportunities for Wednesday. The upper ridge axis moves over the Pacific Northwest on Wednesday night and by Thursday an upper disturbance moves across the eastern Pacific and into northwest Washington and southern British Columbia. The strength and exact track of this disturbance are difficult to assess at this point. If it should stay farther north than forecast then the mixing heights shown below are too optimistic.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY The weather system that brought rain or snow to much of the region on Tuesday moves south and east on Wednesday while an upper level ridge builds to the west and slowly drifts over the Pacific Northwest. The ridge should help stabilize the atmosphere and suppress maximum mixing heights. There is a chance of a lingering shower, especially in southern zones and especially during the morning hours. Otherwise expect partly sunny skies and low maximum mixing heights for poor to marginal smoke dispersal conditions. Winds will be mostly light and variable throughout the day. EXTENDED OUTLOOK (THURSDAY - SATURDAY) The upper ridge moves through during the day on Thursday. By late in the day a Pacific front moves into Oregon and Washington with rain reaching the north coast by late afternoon. By evening much of the region will be experiencing light rain. Maximum mixing heights will improve except in the southern Cascades where ventilation conditions will remain poor. On Friday a broad ridge again builds over the eastern Pacific and noses in over the Pacific Northwest. Ventilation conditions well remain generally fair except in the southern Cascades. Winds will be light and variable in the north but generally northerly for southern zones. This will likely be an opportunity to take care of units requiring northerly flow in that area. Expect little change for Saturday except the northerly transport winds will cover the entire region. 2.

Friday's burning instructions will be issued early Friday morning. 1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 THURSDAY A transitory upper-level ridge of high pressure will slide east of the region, around midday, with a weak cold front coming onshore in the late afternoon and evening. Ahead of the front, transport winds will be mostly southerly with smoke dispersal conditions fair north and only marginal to fair south. Between one-tenth and one-quarter of an inch of rain is expected north, beginning late in the day, with generally one-tenth of an inch or less south. Transport winds will turn more westerly late, with snow levels lowering to near 4000 feet. Precipitation is forecast to turn showery and taper off overnight. OUTLOOK (FRIDAY-SUNDAY) A flat upper-level ridge, in the eastern Gulf of Alaska, will bring a drying and cool northwesterly flow aloft to the region on Friday. There may still be a few residual morning showers, mainly north. Transport winds will be variable across the north but will likely turn northerly over the southern zones. The building upper-level ridge will act to suppress mixing heights somewhat, especially south, with marginal to fair smoke dispersal conditions. A stabilizing air mass will quickly drop mixing heights in the evening. A broad upper-level ridge will continue to amplify offshore, Saturday and Sunday, with a strong north-northwesterly flow aloft over Oregon. Skies should stay mostly cloudy with a chance of light rain at times, mainly north. There may also be areas of morning valley fog, mainly south. Northern mountains could pick up as much as one-tenth of an inch of rain, over the weekend, while many southern locations stay dry. The snow level will rise above 8000 feet. Warming aloft will suppress mixing heights with marginal to poor smoke dispersion. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 TODAY A flat upper-level ridge, in the eastern Gulf of Alaska, will bring a drying and cool northwesterly flow aloft to the region. Residual low-level moisture will combine with a stabilizing air mass to produce areas of dense valley fog this morning, mainly from Lane County north. Transport winds will be variable across the north and light northerly across the southern zones. That will likely create an opportunity to take care of some southern units requiring northerly winds. Temperatures aloft will remain cool enough for fair afternoon mixing, but look for evening mixing heights to drop quickly. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SATURDAY A broad upper-level ridge will continue to amplify offshore. A warm front will track along a strong jet stream, on the north side of the ridge, and drop into the Pacific Northwest. That will bring cloudy skies and some light rain to northern and western zones, with mostly cloudy skies and a chance of light rain to the southeastern zones. There may also be areas of morning valley fog, mainly south. Rainfall totals should range from up to one-half inch in the northern coastal mountains to less than one-tenth of an inch in the southern Cascades. The snow level will rise above 8000 feet. Warming aloft will suppress mixing heights. Transport winds will turn southerly across the northern zones and become light over southern zones with generally marginal to poor smoke dispersal conditions. OUTLOOK (SUNDAY-TUESDAY) The warm front is forecast to dissipate over Oregon on Sunday, as the offshore upper-level ridge continues to build. The flow aloft will turn from northwesterly to more northerly and begin to dry out. Skies should remain mostly cloudy with areas of light rain tapering off in the afternoon. Look for rainfall totals to be less than one-tenth of an inch. The snow level will rise to near 10,000 feet. Warm air aloft will keep mixing heights suppressed with light winds making for generally poor smoke dispersal conditions. The offshore ridge will begin to flatten on Monday, allowing a weak weather system to slide down the southern British Columbia coastline. That will bring back a chance of rain to northern zones with the snow level dropping to about 8000 feet. Southern zones will likely stay dry but with considerable clouds and areas of morning valley fog. Ventilation conditions should improve to marginal. Strong northwesterly flow aloft is forecast for Tuesday with a weak and transitory ridge limiting shower activity. Snow levels will continue to drop to around 5000 feet north and 7000 feet south. Smoke dispersal conditions will likely remain marginal. 2. DISPERSION Zone 601-612 (North Coast Range and Cascades): MORNING Mixing height below 800 ft early rising to 1000 - 1700 ft by late morning.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 MONDAY Upper air charts show a high pressure area centered about 600 miles west of San Francisco and an upper level disturbance moving across the top of the high into British Columbia. This helps maintain a weak warm front that moves over the Pacific Northwest bringing light rain to northern sections of Oregon. Upper level winds will be northwesterly. Expect mostly cloudy skies with light rain in the north, and just mostly cloudy skies in the south. Low level winds will be onshore, generally westerly to southwesterly in the north and northwesterly to north in the south. Warm air aloft with the warm front will stabilize the atmosphere for reduced maximum mixing heights. Look for marginal smoke dispersal conditions in the north and poor conditions in the south. EXTENDED OUTLOOK (TUESDAY - THURSDAY) The upper disturbance moves British Columbia and northern Washington early Tuesday - cooler temperatures aloft behind this system will allow for higher maximum mixing heights and improved ventilation conditions. Transport winds will be generally northwest to southwest in the north and light northwest to northeast in the south. By Wednesday a deep low in the Gulf of Alaska, both at the surface and aloft, begins to influence weather in the Pacific Northwest. Winds turn southerly both at the surface and aloft. A surface cold front moves into western Washington then drops south into northwest Oregon by afternoon. The cold front presses through with rain and snow Thursday morning. The snow level will drop to near 1000 feet in the north and 2000 feet in the south before rising again Thursday afternoon. Expect marginal to fair smoke dispersal conditions Wednesday and Thursday. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 1000 - 1800 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 A broad flat ridge is centered off the Oregon Washington coast. Upper level flow is from the west-northwest over the region. Low level (transport) flow will be generally from the west or northwest except areas of north-northeast flow over the south coast range. There is still a chance for a shower or two in the morning in the north, otherwise look for mostly cloudy skies in the north and partly cloudy skies in the south. Smoke dispersal conditions will be mostly fair. OUTLOOK (WEDNESDAY - FRIDAY) A deep low, both at the surface and aloft develops in the Gulf of Alaska and begins to move toward the Pacific Northwest Wednesday. A Pacific cold front will push into Washington then drop southward, reaching NW Oregon by late morning. The front will spread rain across the most of western Oregon by Thursday morning. Snow levels will drop in the Cascades. Latest models suggest a snow level of about 3500 feet in the north and 4000 feet in the south by Thursday morning. Additional cold air may drop snow levels a little lower by Friday morning, but moisture will be limited by then so little snow is likely. Mixing heights should allow for generally fair to good smoke dispersal conditions throughout the outlook period. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY A deep upper level low near the Queen Charlotte Islands supports a strong Pacific front on Wednesday. This front will move into Washington then drop southward into extreme northwestern Oregon by early afternoon. Rain, occasionally heavy, spreads south and east Wednesday afternoon and night. Snow levels will drop to around 3000 feet Wednesday night and another thousand feet or so by Thursday morning. Transport winds will be south-southwest and maximum mixing heights should rise enough to give generally fair to good smoke dispersal conditions. EXTENDED OUTLOOK (THURSDAY - SATURDAY) The upper low moves to about 150 miles west of Forks, Washington on Thursday. The steady precipitation ends from the north but mostly cloudy skies and scattered showers will remain. The snow level will be around 2000 feet in the north and lower to about 3000 feet by evening in the south. Transport winds will be south to southwesterly in the north and southwesterly to west in the south. On Friday the upper low weakens but a deep cool trough remains just offshore and a surface low continues to spin off the Washington coast. This will push areas of rain or mountain snow into western Oregon but smoke dispersion conditions will remain fair. On Saturday atmospheric models show a new upper level low dropping into the offshore trough with the low center about 200 miles west of Waldport. There will be limited moisture, but showers are likely and the snow level will occasionally drop to as low as 1000 feet. Expect fair to good smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 THURSDAY A vigorous cold front will move east of northern zones in the pre-dawn hours and continue southeastward across the southern zones by midday. Blustery winds will taper off and steady precipitation will turn to showers, from north to south, in the wake of the front. A very cold upper-level trough will drop southward along the British Columbia coastline, to just off the Pacific Northwest coast, with strong westerly flow aloft developing over Oregon. Snow levels will rapidly drop with accumulating snow likely above about 2000 feet north and 3000 feet south. Expect good smoke dispersal conditions. OUTLOOK (FRIDAY-SUNDAY) A very cold upper-level trough will remain over the region during the outlook period with generally fair to good smoke dispersal conditions. A surface low-pressure center will slowly sag southward, to just off the central Oregon coast, on Friday, with southwesterly transport winds backing to southeasterly across the northern zones. Snow levels will hold at near 2000 feet north and drop to about 2500 feet south with showers, mainly over higher terrain. Little change in the overall pattern is forecast for Saturday and Sunday, with snow levels slowly dropping to around 1000 feet north and 2000 feet south by Sunday. Transport winds will likely maintain a southerly component. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height above 5000 ft. Transport wind SW at 18 - 32 mph.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 FRIDAY The axis of a cold upper-level trough will remain just offshore with a moist and very strong west-southwesterly flow aloft over Oregon. Impulses dropping southward into the trough will act to maintain a weak surface low-pressure area off the Washington coast. Circulation around that system will feed ample moisture onshore for scattered showers across all zones, with upslope flow enhancing showers on west-facing mountain slopes. Cold air aloft will keep the snow level near 2000 feet north and 2500 feet south. Expect good smoke dispersal conditions with south to southwesterly transport winds. OUTLOOK (SATURDAY-MONDAY) A fairly strong upper-air disturbance will deepen the offshore trough, with both a surface and upper-air circulation center forecast to strengthen and drift southward, to just off the southern Oregon coast, by Saturday evening. That will weaken the transport winds, with a drier offshore component likely developing, over the northern zones, by late-afternoon. Transport winds should remain southwesterly over the southern zones with a better chance of showers. Snow levels will drop to 1500 feet north and 2000 feet south with fair to good smoke dispersal conditions. On Sunday, the offshore trough will get forced inland, across northern California, with some rain and snow showers circulating northward over the extreme southern zones. Meanwhile, a mostly dry northwesterly flow aloft will bring partial clearing to the northern zones with just a slight chance of showers. Snow levels will drop to near 1000 feet north and 2000-2500 feet south. Smoke dispersal conditions will remain fair to good with increasing southwesterly transport winds. By Monday, the flow aloft is forecast to turn northwesterly, in response to a cold upper-level system dropping southward from British Columbia. The track of this system is still uncertain, so it may not produce much in the way of precipitation. However, it appears likely that it will usher the coldest air of the season into the region. Snow levels will drop to near sea-level across the northern zones and to near 1500 feet over the southern zones. Smoke dispersal conditions should remain fair to good with mostly northwesterly transport winds. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SATURDAY A cold upper-level trough will remain anchored over the region with the trough axis staying just offshore. A fairly strong upper-air disturbance will drop southward, into the parent trough, with a corresponding surface low-pressure center developing off the Washington coast and drifting southeastward during the day. Showers will circulate onshore with the surface low-pressure center forecast to eventually move inland, near the Oregon/California border, late. That will increase the precipitation across the extreme southern zones. Transport winds should maintain a southerly component over the southern zones with an increasing offshore flow over the northern zones. Snow levels will drop to 1500 feet north and 2000 feet south with good smoke dispersal conditions. OUTLOOK (SUNDAY-TUESDAY) A cold upper-level trough will remain over the region, on Sunday. One disturbance will rotate inland early, bringing rain and snow to mainly the most southern zones. The northern zones will come under the influence of an even colder northwesterly flow aloft. Smoke dispersal conditions will remain good with increasing south to southwest transport winds. Another upper-level disturbance is forecast to drop southward, from British Columbia, to just off the Washington and northern Oregon coast late in the day. That system appears to have enough moisture to bring increasing showers to all zones. Snow levels will drop to near 1000 feet north and 1500-2000 feet south. By Monday, the flow aloft is forecast to turn northwesterly, with an even colder upper-level system dropping southward, from British Columbia, into the region. This system will be accompanied by a surface Arctic cold front, which will usher the coldest air of the season into the region. The track of this system is still uncertain, but if it has enough moisture to work with, it will bring snow to even the lowest elevations in the northern zones. Snow levels will drop to near 1500 feet over the southern zones. Smoke dispersal conditions should remain good. Transport winds will be mostly westerly but will switch to northerly across the northern-most zones late. On Tuesday, a very cold and drier northerly flow is forecast, with sub-freezing morning temperatures, and possibly snow-covered ground, across most zones. Skies will stay partly to mostly cloudy with a slight chance of showers. The snow level will be at sea-level north and near 1500 feet south. Cold low-level air will stabilize the air mass, especially north, with light north to east winds. Smoke dispersal conditions will likely decrease to marginal-to-fair. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SUNDAY A cold upper-level trough will remain over the region. One disturbance will rotate inland early, bringing rain and snow to the most southern zones. The northern zones will come under the influence of an even colder, but drier, northwesterly flow aloft. Smoke dispersal conditions will remain good with increasing south to southwest transport winds. Another upper-level disturbance is forecast to drop southward, from British Columbia, to just off the Washington and northern Oregon coast by late in the day. That system will back the upper-level flow, giving it a more over-water trajectory, and increase the shower activity, from north to south, across western Oregon. Snow levels will drop even lower Sunday evening, with accumulating snow possible down to 500 feet north and 1500 feet south by Sunday night. OUTLOOK (MONDAY-WEDNESDAY) On Monday, an even colder upper-level system will drop southward and renew the shower activity across western Oregon. This system will be accompanied by a surface Arctic cold front, which will locally enhance precipitation and drop snow levels to the valley floors, as it slowly sags southward across western Oregon Monday afternoon and evening. The latest computer guidance is supporting accumulating snow in western valleys, as well as higher terrain, before a drier northerly flow aloft tapers off the precipitation, from north to south, Monday night. Snow levels will drop to near 1500 feet over the southern zones. Smoke dispersal conditions should remain good. Transport winds will be mostly westerly but may turn northerly across the northern zones late. On Tuesday, a very cold and drier northerly flow is forecast, with sub-freezing morning temperatures, and possibly snow-covered ground, across most zones. Skies will clear, from north to south, with a chance of showers south early. The snow level will stay near sea level north and 1500 feet south. Cold low-level air will stabilize the air mass, especially north, with light transport winds. Smoke dispersal conditions will likely deteriorate to only marginal to fair. Computer models show an upper-level ridge building over the region by Wednesday with a dry and much more stable northerly flow aloft. That will lead to very cold overnight temperatures, especially in snow-covered areas, and surface-based inversions. A weak impulse in the northerly flow is forecast to bring some middle and high clouds to the region in the afternoon but will not likely be strong enough to produce any precipitation. Smoke dispersal conditions will further deteriorate, to poor, in most zones. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 MONDAY A cold weather pattern has set up for the Pacific Northwest. In the upper atmosphere a strong ridge of high pressure has developed up in the eastern Pacific and the Gulf of Alaska with a cold trough extending from north-central Canada into southern California. This leaves the Pacific Northwest in a cold northerly flow aloft. Computer models indicate one disturbance in this northerly flow will move through the region Sunday afternoon and evening with another following Monday night and early Tuesday. The latest model runs are also more aggressive with the potential for significant low level snow, especially in northern sections. Some light accumulation (less than an inch) is possible in valley locations the north Sunday night and early Monday. For southern zones the snow level will likely be about 2500 feet and above for Monday. Mountain locations will generally receive 2-4 inches of new snow through Monday evening. Smoke dispersal conditions will be generally fair with most areas seeing a southwesterly transport wind, but a northerly component to the transports will develop in the northern zones. EXTENDED OUTLOOK (TUESDAY - THURSDAY) The upper disturbance that moves through Monday afternoon and evening has the potential to be a significant snow producer for virtually all of western Oregon. Snow levels will reach to all elevations of interior western Valleys. Accumulations depend on the amount of available moisture. As mentioned above, latest model runs are more aggressive with snow amounts. At the high end, 2-4 inches is possible late Monday in the Willamette Valley with greater amounts at higher elevations. Drier air will filter into northern sections to end the snow Tuesday. Southern valley locations could see 1-3 inches during the day on Tuesday. Smoke dispersal conditions will be mostly fair to good throughout western Oregon. For Wednesday and Thursday, the cold upper trough will move east and the ridge in the Pacific will begin to move over the area. Upper flow will be northerly and dry for mostly sunny weather. Temperatures, however, will remain cool. Cold nighttime temperatures will promote overnight inversions that will be slow to break and limit maximum mixing heights. Thus smoke dispersal conditions will be marginal Wednesday and beyond. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 2500 - 3500 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 TUESDAY An upper level trough, oriented NE to SW moves southeastward across the region on Tuesday. This supports a cold front - the leading edge of modified arctic air - as it also sweeps across the region Monday night and early Tuesday morning. This front will usher in cooler temperatures for mid week. Low elevation snow will fall as the front passes through, then drier air will filter southward to end any precipitation. Monday evening totals in the lowlands of northwest Oregon will still be on the ground early Tuesday morning. Estimates as of Monday afternoon are one-half to one and one-half inches. In the south, the Rogue Valley can expect some snow during the day on Tuesday with about one to two inches likely. Mountain areas in western Oregon should get 3 to 5 inches of new snow. Temperatures will fall during the day with the highest temperatures most areas occurring mid-morning. Smoke dispersal conditions should be generally fair, but northern zones will see just light and variable, mainly northerly, winds with southern sections seeing northwesterly winds most of the day. EXTENDED OUTLOOK (WEDNESDAY - FRIDAY) By Wednesday upper level flow is northerly, cold, and generally dry over the Pacific Northwest. Scattered snow showers are still possible, however. The cold surface temperatures and sinking air aloft will limit maximum mixing heights and smoke dispersal conditions will be marginal at best. An upper ridge axis passes through early Thursday and upper flow backs to more westerly. Maximum mixing heights should improve in the north but deteriorate in the south. On Friday a strong westerly flow aloft over the eastern Pacific and the Pacific Northwest will push a Pacific cold front into northwestern Oregon early in the day. As this system moves east it will bring rain to much of the state. The wet system will hit the north coast first, then spread rain south and east, with precipitation reaching Grants pass by late in the afternoon. The snow level with this front will be around 4000 feet. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 2200 - 3200 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Arctic air drove down from the north last night and early this morning and will set up shop for the next couple of days before gradually moderating. Air mass is moderately unstable today but as the surface temperatures cool tonight, strong temperature inversions will form and limit mixing overnight. As the upper ridge off the coast slowly moves in the air will slowly warm aloft. With chilly air near the surface, this will make for mostly poor mixing Wednesday. Wind flow will also be quite light under little pressure gradients. Thus smoke dispersion will be quite poor. OUTLOOK (THURSDAY - SATURDAY) A flattening upper level ridge builds in on Thanksgiving bringing warming temperatures aloft and near the surface. Another front will approach from the Pacific bringing increasing clouds and the chance of rain by Thursday evening. Snow level will lift to near 4000 - 5000 ft. Cold front moves through on Friday and will be followed by a chilly and unstable upper level trough on Saturday. Snow level will lower to near 2000 ft. Air mass will remain stable through Friday before destabilizing on Saturday. Wind flow will increase from the SE to S on Thursday, turn S to SSW on Friday, and then decrease and turn more SW to W on Saturday. Smoke dispersion will be poor Thursday, improving Friday, and good to excellent on Saturday. 2.

If there are landowners thinking of burning over the holiday weekend, please call to coordinate by 4 p.m. this afternoon.**** 1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level ridge is building into the region today and will gradually moderate the arctic air that's been over the state since yesterday. Ridge will slowly flatten on Thanksgiving as the next frontal system approaches. Cloud cover today is mainly the result of a strong jet stream coming down from the north which is part of our current cold spell. Higher clouds should slowly dissipate overnight as the ridge moves inland. Air mass is stabilizing and may lead to some fog formation in the valleys tomorrow morning. Next front will increase clouds later Thursday but moisture is generally not expected until Friday. With residual surface cold air and warming aloft, along with only light wind flow, expect very poor smoke dispersion. OUTLOOK (FRIDAY - SUNDAY) Forming upper level trough in the eastern Pacific will eject a front into the state on Friday, bringing increasing rain Friday morning. The front will gradually scour the air shed on Friday. However, the air mass will not likely destabilize completely until Saturday when the upper level trough arrives. Rain turns to showers on Saturday. Snow level will rise to near 5000 ft Thursday and Friday, then lower to near 2000 ft on Saturday. Upper trough moves off to the east on Sunday with a minor ridge moving in during the afternoon. Air mass should remain mostly unstable on Sunday then stabilize Sunday evening. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 An upper level ridge is sliding across Washington and Oregon this morning. Valley locations are seeing inversions to limit stability this morning and allowing locally dense fog to develop in the colder air trapped near the surface. However, a potent low pressure system is developing over the eastern Pacific. This will push a strong Pacific front toward the Pacific Northwest coast this afternoon. This system will bring precipitation to the region beginning this afternoon and spreading south and east during the late afternoon and overnight tonight. This system will bring strong winds to the coast and heavy snows to the mountains tonight and tomorrow. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 TUESDAY The upper ridge that was over the region Monday moves east on Tuesday leaving southwesterly flow aloft over the Pacific Northwest. An active pacific front will slowly move in during the day. Rainfall will begin Monday evening in the north but not reach southwest Oregon until Tuesday afternoon. In the north precipitation amounts should range from about three-quarters of an inch to about an inch. Only light rain (less than about .15) is likely Tuesday afternoon in southern sections. Ahead of the front the snow level will be around 5000 feet, but as the front passes through snow levels will drop to around 3000 feet. Mixing heights should be quite high and fairly strong southerly transport winds will develop ahead of the front. Thus smoke dispersal conditions should be good most areas. EXTENDED OUTLOOK (WEDNESDAY - FRIDAY) The front will stall on a line from NE Oregon to NW California on Wednesday. Subsidence behind the front will limit maximum mixing heights and winds will go light. Smoke dispersal conditions will drop to just fair. On Thursday a wave forms on the front off the northern California coast which will increase rainfall in SW Oregon again. Mixing heights will improve in the south but drop even farther in the north. Northern zones will see just marginal ventilation conditions Thursday. The front loses strength and moves to the east on Friday and the air mass remains stable in the north and stabilizes in the south so that all zones will see only marginal conditions by Friday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY The cold front that brought rain and snow to much of the region Tuesday and Tuesday night is south and east of the area for Wednesday. What remains of the weakening system are now in Idaho, northern Nevada, and northern California. Scattered showers remain, but the air mass will rapidly stabilize and smoke dispersal conditions will be in the fair range. Transport winds will be light and generally southwesterly in the north with a slightly stronger southwesterly transport flow for southern zones. EXTENDED OUTLOOK (THURSDAY - SATURDAY) An upper short wave re-energizes the front to the south on Thursday pushing precipitation back into the region. Southern sections will see greater amounts, but northern areas will see renewed precipitation as well. A drier pattern sets up for the Friday and the weekend and maximum mixing heights will be held down for likely marginal to perhaps poor smoke dispersal conditions later in the extended period. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY The cold front that brought rain and snow to much of the region Tuesday and Tuesday night is south and east of the area for Wednesday. What remains of the weakening system are now in Idaho, northern Nevada, and northern California. Scattered showers remain, but the air mass will rapidly stabilize and smoke dispersal conditions will be in the fair range. Transport winds will be light and generally southwesterly in the north with a slightly stronger southwesterly transport flow for southern zones. EXTENDED OUTLOOK (THURSDAY - SATURDAY) An upper short wave re-energizes the front to the south on Thursday pushing precipitation back into the region. Southern sections will see greater amounts, but northern areas will see renewed precipitation as well. A drier pattern sets up for the Friday and the weekend and maximum mixing heights will be held down for likely marginal to perhaps poor smoke dispersal conditions later in the extended period. 2.
