DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 TUESDAY *** 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 partly cloudy skies. Mixing heights will be suppressed and transport winds will be mostly light and variable. EXTENDED OUTLOOK (WEDNESDAY - FRIDAY) *** Marginal or Occasionally Poor 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. An upper disturbance moving through on Friday will lift maximum mixing heights to more favorable levels. 2. DISPERSION TUESDAY Mixing height below 500 ft early rising to 1400 - 2400 ft by late morning. Afternoon mixing height rises to 2000 - 3000 ft then lowers to 1000 - 1700 ft during the evening.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 WEDNESDAY *** Poor 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 aloft will be much 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 southeast and light, while mixing heights will be quite low. EXTENDED OUTLOOK (WEDNESDAY - FRIDAY) *** Marginal Ventilation for 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. Smoke dispersal conditions become good with a brisk south or south-southwesterly transport wind developing. The initial weather system will likely not produce rain on Friday, but more moisture moves into the Pacific Northwest for some rain possible Saturday. 2.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 THURSDAY *** 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 will be generally south to southeasterly with suppressed mixing heights for unfavorable ventilation conditions. Transport winds will be generally south or southeasterly. 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. Transport winds will be generally southerly. The upper trough moves through early Saturday and there will be some stabilization during the afternoon. However another relatively weak front will brings more rain during the evening. Expect a few left-over showers Sunday, good smoke dispersal conditions and transport winds mostly from the southwest. 2. DISPERSION THURSDAY Mixing height below 1000 ft during the morning.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 FRIDAY The massive upper-level ridge of high pressure that has been bringing unseasonably warm temperatures 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 just a few clouds will drifting over the region. Warm air aloft will continue to suppress mixing heights. However, increasing southerly surface and transport winds may locally mix warmer air aloft to the surface, resulting in near-record warm surface temperatures and improved 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 stay offshore until evening. Clouds will be on the increase over south-central Oregon with a slight chance of light showers rotating over the region from California. South to southwesterly winds will keep surface temperatures well above normal, and cooling aloft will raise afternoon mixing heights, making for good smoke dispersal conditions. A cold front will likely spread rain across western Oregon by Saturday night and into south-central Oregon Sunday morning. Rain will turn to showers later Sunday afternoon. Rainfall amounts should range from one-tenth to one-quarter of an inch. Surface temperatures will cool to near normal. Cooler air aloft will drop the snow level to around 5000 feet, by evening, with continued good afternoon smoke dispersal conditions. Showers will taper off 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, mainly east in the morning. Transport winds will remain onshore with fair to good smoke dispersal conditions. 2. DISPERSION FRIDAY Mixing height below 800 ft early rising to 2000 - 3000 ft by late morning. Afternoon mixing height rises to 3000 - 4000 ft then lowers to 1000 - 2000 ft during the evening. Transport wind SSW to SW at 12 - 22 mph during the morning and afternoon.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 SATURDAY The massive upper-level ridge of high pressure responsible for the recent spell of dry, warm and stagnant conditions will continue to weaken and shift eastward. The ridge axis is forecast to stretch from New Mexico to North Dakota with strengthening southwesterly flow aloft over Oregon. The second in a series of weather systems will approach the coastline late in the day, with partly to mostly cloudy skies but dry conditions expected over south-central Oregon. South to southwesterly winds will keep surface temperatures well above normal, and cooling aloft will raise afternoon mixing heights, making for good smoke dispersal conditions. OUTLOOK (SUNDAY-TUESDAY) A cold front will likely spread rain across south-central Oregon Sunday morning. Rain will turn to showers later Sunday afternoon. Rainfall amounts should range from one-tenth to one-quarter of an inch. Surface temperatures will cool to near normal with continued good smoke dispersal conditions. Cooler air aloft will drop the snow level to around 5000 feet by evening and 4500 feet overnight. Showers will taper off Monday, as a flat and transitory upper-level ridge stabilizes the air mass slightly. Snow levels will remain near 4500 feet and surface temperatures will cool to slightly below normal. Transport winds will turn mostly westerly 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 4500 feet or lower with rainfall amounts possibly in excess of one-quarter of an inch. Transport winds will depend on the exact track of the low-pressure center and may switch quickly from southerly to westerly in the afternoon. Smoke dispersal conditions should remain fair to good. 2.

Rainfall totals will mostly range from one-tenth to one-quarter of an inch and locally up to one-half inch. Afternoon highs will be near 10 degrees below average. Smoke dispersal conditions should be good, but watch for southwesterly transport winds to become more westerly in the afternoon. Cooler air aloft will drop the snow level to around 5000 feet by evening and 4500 feet overnight. OUTLOOK (MONDAY-WEDNESDAY) Some showers will continue Monday, mainly over the mountains, with a drier northwesterly flow aloft bringing some clearing late in the day. Snow levels will remain near 4500 feet with afternoon surface temperatures about 10 degrees below normal. Transport winds will be mostly westerly with fair to good smoke dispersal conditions. Partial clearing is likely Tuesday, with the next weather system not coming onshore until Tuesday afternoon. Smoke dispersion should be fair to good with southwesterly transport winds.

The low supports a Pacific cold front which will bring rain to the region much of the day. Rain spreads east during the late morning or early afternoon. Amounts should be one-third of an inch or less and the snow level should be around 4000 feet. EXTENDED OUTLOOK (WEDNESDAY - THURSDAY) *** 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 will lead to marginal smoke dispersal conditions for Tuesday. 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. For now I will go with significant improvement and better burning conditions for Thursday. On Friday a broad flat ridge has set up over the Pacific Northwest. Expect little change in maximum mixing heights and a generally west to northwest transport wind. 2. DISPERSION TUESDAY Mixing height 2500 - 3500 ft during the morning. Afternoon and evening mixing rises to 3300 - 4300 ft. Transport wind SSW to SW at 18 - 30 mph during the morning. Transport wind increases to SW to WSW at 25 - 43 mph during the afternoon then decreases to SW to W at 22 - 38 mph during the evening. Surface wind SSW to SW at 12 - 24 mph. OUTLOOK: WEDNESDAY Mixing height 2400 - 3400 ft during the morning and through the afternoon. Transport wind WNW to NW at 12 - 22 mph during the morning becoming NNW to NNE at 9 - 15 mph during the afternoon. Surface wind W to NW at 6 - 12 mph during the morning becoming NNW to NNE at 6 - 12 mph during the afternoon. THURSDAY Mixing height below 1000 ft during the morning rising to 2500 - 3500 ft during the afternoon. Transport wind light and variable during the morning becoming SSW to WSW at 4 - 8 mph during the afternoon. Surface wind ESE to SSE at 4 - 8 mph during the morning becoming SSW to WSW at 4 - 8 mph during the afternoon. FRIDAY Mixing height below 1000 ft during the morning rising to 2500 - 3500 ft during the afternoon. Transport wind NW to NNE at 4 - 8 mph. Surface wind NW to NNE at 4 - 8 mph. 3. BURNING INSTRUCTIONS FOR ZONES 624 AND 625 INCLUDING THE WALKER RANGE PORTION OF ZONE 624 This instruction is valid for burning conducted on Tuesday, November 9, 2010. ================================================================== Avoid ignitions within 12 miles to the SW through WSW of SSRAs. For units that will smolder significantly through the night avoid burning within at least 12 miles to the SW through WNW in or near drainages leading to SSRAs. Care needed in selecting units as smoke will likely fumigate along the ground in wind prone areas. No additional restrictions necessary. ============================================================== 4. SPECIAL NOTE: The smoke management forecaster is available at (503) 945-7401. The smoke management forecaster is available to discuss specific burns. The duty forecaster phone number is (503) 945-7401.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 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. However, expect mostly cloudy skies and a few lingering showers. Ventilation conditions will be mostly fair and winds generally northwesterly. EXTENDED OUTLOOK (THURSDAY - SATURDAY) The upper ridge moves through during the day Thursday. Maximum mixing heights remain suppressed with poor to marginal smoke dispersal conditions. Winds most areas will be light and variable becoming southerly later in the day. On Friday a broad ridge again builds over the eastern Pacific and noses in over the Pacific Northwest. Dryer weather and more sunshine will warm near-surface layers and push maximum mixing heights higher to improve ventilation conditions for both Friday and Saturday. 2. DISPERSION WEDNESDAY Mixing height 2400 - 3400 ft during the morning and afternoon. Mixing height lowers below 1000 ft during the evening. Transport wind WNW to NNW at 6 - 10 mph during the morning.

Friday's burning instructions will be issued early Friday morning. 1. DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 THURSDAY A transitory upper-level ridge of high pressure will slide over the region, around midday, and then advance eastward into Idaho. That will bring a dry day with at least partly sunny skies. A weak cold front will move onshore in the late afternoon and evening. Ahead of the front, south to southwesterly transport winds will increase in the afternoon. Warming aloft will suppress mixing heights with marginal to poor smoke dispersal conditions. OUTLOOK (FRIDAY-SUNDAY) A weak cold front will bring a chance of light showers Thursday night through Friday morning, with snow levels near 4000 feet. Rainfall totals should be less than one-tenth of an inch. A flat upper-level ridge, in the eastern Gulf of Alaska, will bring a drying and cool northwesterly flow aloft to the region Friday afternoon. Westerly transport winds will turn more northerly by afternoon with improved mixing yielding 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 Saturday with a slight chance of a light shower. More clearing is forecast for Sunday. The snow level will slowly rise to above 7000 feet.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 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. Skies should become mostly cloudy with a slight chance of light rain in the afternoon. The snow level will slowly rise to above 7000 feet. Warming aloft will suppress mixing heights with 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 a slight chance of light rain. The snow level will rise to near 8,000 feet. Warm air aloft will keep mixing heights suppressed with continued marginal to 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 maintain at least partly cloudy skies, but it should stay dry with the snow level remaining near 8000 feet. Ventilation conditions should remain marginal to poor. Strong northwesterly flow aloft is forecast for Tuesday with a weak and transitory ridge allowing for more afternoon sunshine.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 SUNDAY A broad upper-level ridge will continue to amplify just offshore. A warm front is forecast to slowly weaken over Oregon, as the flow aloft turns from northwesterly to more northerly and begins to dry out. Skies should remain mostly cloudy with a slight chance of rain. The snow level will rise to near 9,000 feet. Warm air aloft will keep mixing heights suppressed with marginal smoke dispersal conditions. OUTLOOK (MONDAY-WEDNESDAY) The offshore ridge will begin to flatten on Monday, allowing a weak weather system to slide down the southern British Columbia coastline.

This helps maintain a weak warm front that moves over the Pacific Northwest. Upper level winds will be northwesterly. Warmer air aloft with the warm front will stabilize the atmosphere somewhat but mixing heights should remain high enough for fair smoke dispersal conditions. EXTENDED OUTLOOK (TUESDAY - THURSDAY) The atmosphere further stabilizes Tuesday and smoke dispersal conditions become marginal. Transport winds will be generally westerly. 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 but rain will hold off until Thursday. Cooler air aloft on Thursday means a less stable atmosphere and improves smoke dispersal conditions. 2. DISPERSION MONDAY Mixing height 2000 - 3000 ft during the morning. Afternoon and evening mixing rises to 2800 - 3800 ft. Transport wind NNW to NNE at 15 - 29 mph during the morning. Transport wind decreases to NW to NNW at 12 - 22 mph during the afternoon and evening. Surface wind NNW to NNE at 10 - 16 mph during the morning and afternoon. Surface wind decreases to W to NW at 4 - 8 mph during the evening. OUTLOOK: TUESDAY Mixing height 1200 - 2200 ft during the morning rising to 1800 - 2800 ft during the afternoon. Transport wind W to NW at 10 - 20 mph. Surface wind SW to WNW at 4 - 8 mph during the morning becoming W to NW at 6 - 12 mph during the afternoon. WEDNESDAY Mixing height below 1000 ft during the morning rising to 2500 - 3500 ft during the afternoon. Transport wind SSE to SW at 4 - 8 mph. Surface wind SSE to SSW at 4 - 8 mph.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 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. Clouds will be on the increase ahead of the front but precipitation will hold off until Thursday. Transport winds will be generally south-southwesterly and mixing heights high enough for fair smoke dispersal conditions. EXTENDED OUTLOOK (THURSDAY - SATURDAY) The upper low moves to about 150 miles west of Forks, Washington on Thursday. Expect light rain as the remains of the front move through the region. Transport winds will be mostly light and variable and smoke dispersal conditions will be good. 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. Areas of light precipitation will persist and smoke dispersal conditions will remain good. 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 for a few showers and maximum mixing heights should top 5000 feet. 2. DISPERSION WEDNESDAY Mixing height below 1000 ft during the morning.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 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 rain and snow showers. Cold air aloft will keep the snow level in the 3000-3500 foot range. 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. A moist southwesterly flow aloft will maintain mostly cloudy skies with some rain and snow showers. The snow level will drop to between 2500 and 3000 feet. Transport winds should remain southwesterly with good smoke dispersal conditions. On Sunday, the offshore trough will get forced inland, across northern California, with some rain and snow showers likely circulating northward over the region. Snow levels will drop to between 2000 and 2500 feet. Expect fair to good smoke dispersal conditions with transport winds turning more westerly. 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, but it should produce at least some showers. It appears likely that it will usher the coldest air of the season into the region with any precipitation falling in the form of snow. Smoke dispersal conditions should remain fair to good with west to northwesterly transport winds. 2. DISPERSION FRIDAY Mixing height below 2000 ft early rising to 3000 - 4000 ft by late morning. Afternoon mixing height rises above 5000 ft then lowers to 2000 - 3000 ft during the evening. Transport wind SW to WSW at 10 - 22 mph during the morning and afternoon.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 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. A moist southwesterly flow aloft will maintain mostly cloudy skies with snow showers. Transport winds should turn mostly southerly with good smoke dispersal conditions. Look for snow to increase late, with accumulations likely, as the surface low-pressure area comes onshore. OUTLOOK (SUNDAY-TUESDAY) A cold upper-level trough will remain over the region, on Sunday. One disturbance will rotate inland, across northern California, with accumulating snow likely across most of the region. Expect good smoke dispersal conditions with westerly transport winds. Snow may taper off in the afternoon, but 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 should bring a renewed threat of snow to the region by Sunday night, along with even colder air. 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 it will likely bring accumulating snow to the entire region by late in the day. Smoke dispersal conditions should remain good with brisk westerly transport winds. On Tuesday, a very cold and drier northerly flow is forecast, with sub-freezing temperatures and snow-covered ground likely. Skies will stay partly to mostly cloudy with a chance of light snow showers. Cold low-level air will stabilize the air mass, with light winds and only marginal to fair smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 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. There will be enough moisture for snow although amounts should be light, generally less than an inch although some locations could get as much as 2 inches. Smoke dispersal conditions will be generally good with most areas seeing a southwesterly transport wind. EXTENDED OUTLOOK (TUESDAY - THURSDAY) The upper disturbance that moves through Monday afternoon and evening will bring another round of snow to the area. The snow will be tapering off on Tuesday as a drier flow moves over the region. Smoke dispersal conditions will be fair to good. 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 MONDAY Mixing height 3500 - 4500 ft throughout the day. Transport wind WSW to W at 26 - 46 mph during the morning. Transport wind increases to SW to W at 32 - 52 mph during the afternoon and increases to SW to W at 37 - 57 mph during the evening. Surface wind WSW to W at 16 - 30 mph during the morning and afternoon. Surface wind increases to SW to WSW at 21 - 37 mph during the evening. OUTLOOK: TUESDAY Mixing height above 5000 ft throughout the day. Transport wind WNW to NW at 18 - 32 mph during the morning becoming NW to NNW at 10 - 20 mph during the afternoon. Surface wind W to NW at 10 - 22 mph. WEDNESDAY Mixing height below 1000 ft during the morning rising to 2000 - 3000 ft during the afternoon. Transport wind light and variable. Surface wind light and variable. THURSDAY Mixing height below 1000 ft early rising to 1000 - 2000 ft by late morning rising to 2000 - 3000 ft during the afternoon. Transport wind light and variable during the morning becoming SSE to SSW at 4 - 8 mph during the afternoon. Surface wind SSE to SSW at 4 - 8 mph. 3. BURNING INSTRUCTIONS FOR ZONES 624 AND 625 INCLUDING THE WALKER RANGE PORTION OF ZONE 624 This instruction is valid for burning conducted on Monday, November 22, 2010. ================================================================== Avoid ignitions within 10 miles to the SW through W of SSRAs. For units that will smolder significantly through the night avoid burning within at least 10 miles to the SW through WNW in or near drainages leading to SSRAs. Care needed in selecting units as smoke will likely fumigate along the ground in wind prone areas.

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 SOUTH CENTRAL OREGON ZONES 624 AND 625 Arctic air drove down from the north 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 mass 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 on Friday. Moisture will not likely begin until later Friday with scattered snow showers through Saturday. Air mass will remain stable through Friday before destabilizing on Saturday. Wind flow will increase from the S to SW on Thursday, increase more on Friday, and then decrease and turn more W to NW on Saturday. Smoke dispersion will be poor Thursday, improving Friday, and good to excellent on Saturday. 2. DISPERSION WEDNESDAY Mixing height below 1000 ft during the morning. Afternoon mixing height rises to 1700 - 2700 ft then lowers below 1000 ft during the evening. Transport wind light and variable and controlled by local terrain during the morning.

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 SOUTH CENTRAL OREGON ZONES 624 AND 625 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. 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 clouds Friday with a chance of moisture overnight into Saturday. The front will gradually scour the air shed Friday and into early Saturday. However, the air mass will not likely destabilize completely until Saturday afternoon when the upper level trough arrives. Snow level will rise to near 5000 ft Thursday night and Friday, then lower to near the surface on Saturday. Upper trough moves off to the east on Sunday with a minor ridge moving in during the evening. Air mass should remain mostly unstable on Sunday then stabilize Sunday night. 2. DISPERSION THURSDAY Mixing height below 1000 ft during the morning. Afternoon mixing height rises to 1000 - 2000 ft then lowers below 1000 ft during the evening.
