DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SATURDAY The strong upper-level ridge over the Pacific Northwest will weaken and continue to slowly shift eastward, with the ridge axis over Idaho and western Montana. Transport winds will turn mostly northerly with warm air aloft continuing to suppress mixing heights. Ventilation conditions will be marginal. OUTLOOK (SUNDAY-TUESDAY) The upper-level ridge will shift into Wyoming and eastern Montana by Sunday, with increasing southwesterly flow aloft. The surface thermal trough will progress eastward, into Idaho. Increasingly onshore transport winds and cooling aloft will improve ventilation conditions. A cold front will likely bring some light rain to most areas late Sunday and Monday with continued onshore transport winds and good daytime mixing. Transport winds are forecast to turn northerly by Monday night, and offshore on Tuesday, as a ridge of high pressure begins building back over the west coast. Inversions are likely Tuesday morning with warming aloft suppressing afternoon mixing heights. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 MONDAY A full latitude upper level trough moves into the Pacific Northwest on Monday. The atmosphere aloft cools considerably for higher maximum mixing heights. By evening the axis of the trough will be over the Cascade crest and moving east. Models show only limited moisture with this system but a few showers are likely. Transport winds should generally be from the northwest through north. EXTENDED OUTLOOK (TUESDAY - THURSDAY) On Tuesday the southern portion of the upper trough cuts off as an upper level low over southern California leaving the Pacific Northwest under an upper level ridge oriented SW-NE. Warmer air aloft will suppress maximum mixing heights a bit. Winds will be generally northerly to north-northeasterly. On Wednesday the upper level low over California is nearly stationary and cut off from the main westerly flow aloft which is north of the Pacific Northwest. Again warm air aloft holds maximum mixing heights down and smoke dispersal conditions will only be marginal. The upper low over California weakens on Thursday and moves off to the northeast. Mixing heights recover for better ventilation. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 2100 - 3100 ft. Transport wind light and variable.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 TUESDAY Monday's trough splits...a portion moves across central Canada and the rest becomes a cut-off low over southern California. An upper ridge develops offshore and noses into Washington while a surface thermal trough develops in the central valley of California. This will give a northerly flow most areas and dry weather for the region. Warmer air aloft with the ridge will suppress mixing heights. Smoke dispersal conditions will generally be fair. EXTENDED OUTLOOK (WEDNESDAY - FRIDAY) The upper level cut-off low remains over southern California on Wednesday as a thermal trough builds northward overnight Tuesday to off the SW Oregon Coast. It should move onshore and into SW Oregon during the day on Wednesday. This will cause shifting winds. Advise against planning any very large burns or burns close to SSRA's in SW Oregon on Wednesday as we are unlikely to give clearances due to the uncertainty of the wind directions throughout the day. By Thursday afternoon the upper level low is pulling out over NE Nevada. Upper flow over the region is beginning to go southwesterly. Transport level winds will also be south through southwest and weather will continue dry. Friday a front will approach from the west spreading some light rain across mainly the northwestern portion of western Oregon. Warm air streaming northward aloft ahead of the front will suppress mixing heights but transport winds will be southerly and increase considerably. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY A nearly stationary upper level low remains over southern California while the main Pacific jet stream is to the north, cutting into central British Columbia on Wednesday. A thermal trough extends from California's central valley to off the southern Oregon coast. Models show the trough shifting inland during the day. Transport winds will start out easterly but then go light and variable as the trough moves over the area and by the end of the day there will be a slight westerly tendency. With the variable wind direction recommend against large burns or burns near SSRA's. EXTENDED OUTLOOK (THURSDAY - SATURDAY) On Thursday the upper low over California kicks out to the northeast and weakens. The center of the low will be over about Salmon, Idaho by evening. Low level flow will be onshore with a south through southwest transport winds most areas. Temperatures will drop to near average for early October. Upper level flow goes southwesterly by Friday with a weak weather system moving into Washington early in the day. Expect southerly transport winds which will help to push temperatures up a few degrees. A second Pacific weather system spreads rain to most of the region by evening. Saturday begins with rain most areas but the precipitation will be retreating northward during the day. Expect continued southerly transport winds but low mixing heights in the north. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 THURSDAY An upper level low that was over California Wednesday tracks northeast across Nevada and then into Idaho during the day. The thermal trough that was offshore shifts inland for onshore flow. Transport winds will be generally southwesterly. There is a slight chance of a shower in southern zones otherwise expect dry weather. Smoke dispersal conditions will be marginal for northwest zones, elsewhere fair conditions are likely. EXTENDED OUTLOOK (FRIDAY - SUNDAY) The remains of a weak Pacific front brush northwest Oregon early in the day Friday. This will be followed by a stronger system during the late afternoon and evening with widespread rain over the region. Mixing heights should improve and strong southwesterly transport winds are likely. On Saturday another Pacific Cold front moves across the region for additional rain. High pressure noses into the region Sunday for dry weather and weakly offshore flow most areas. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 1000 - 2000 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 FRIDAY A blocking pattern in the upper-level flow will break down, as the trough over Nevada gets ejected eastward to over the northern Rockies. That will increase the westerly flow aloft and open the door for a series of Pacific storms to come onshore. The first front will spread clouds across much of western Oregon with a chance of light rain along the coast and northern inland locations...mainly in the morning. Increasing South-southwesterly transport winds will improve ventilation conditions, in the afternoon, ahead of a stronger front forecast to come onshore Friday night. OUTLOOK (SATURDAY-MONDAY) Two cold fronts will bring widespread rain to the region Saturday and again on Sunday. Brisk south-southwesterly transport winds, on Saturday, will veer to more westerly on Sunday, behind the second cold front. The flow aloft will dry out and turn northwesterly on Monday. Transport winds will turn northerly, with some offshore flow likely across the southern zones. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SATURDAY The jet stream is transitioning to a more autumn-like pattern. A developing westerly flow aloft pushed a very weak cold front across Washington and the northern half of western Oregon on Friday. That system was primarily a cloud-maker with only spotty light rainfall. However, it did cool the air aloft and increase the transport winds enough to improve ventilation conditions. A stronger system, with some entrained tropical moisture, will approach the coastline early Saturday. The bulk of the rainfall is forecast to stay north of Oregon, but some rain is likely across the northern half of the region Saturday morning, with a chance of light rain south. The cold front is forecast to stall and push north, as a warm front, Saturday afternoon and night. That will likely result in a considerable contrast in rainfall, from northwest to southeast, across western Oregon. The north coastal range will see the most rain, perhaps 1-2 inches, while the southern Cascades could stay dry. Increasing southerly transport winds will aid ventilation, but warming aloft and cloud-cover will suppress afternoon mixing heights, especially north and west. Smoke dispersal conditions will be fair in the north and good in the south. OUTLOOK (SUNDAY-TUESDAY) Rain will increase, from west to east, across the entire region Sunday, as the final cold front in this series of Pacific storms comes onshore. Brisk southwesterly transport winds will veer to northwesterly, in the wake of the cold front, Sunday afternoon. There will not be much post-frontal shower activity Sunday evening, because the air aloft will stay fairly mild. The snow level should stay above 7000 feet. Clearing skies should lead to strong surfaced-based inversions by Monday morning with recent rains possibly leading to valley fog formation. The flow aloft is forecast to dry out and turn northwesterly on Monday. Transport winds will turn northerly across the northern zones and northeasterly across the southern zones. That will aid in the drying of the low-level air mass and should help to clear fog from most valley locations in the afternoon. Even with some sunshine, mixing heights will be suppressed by subsidence aloft, associated with the building ridge of high pressure, so smoke dispersal conditions will be marginal at best. Strong surface-based inversions are likely again Tuesday morning, as the upper-level ridge moves directly over Oregon. Areas of morning valley fog and low clouds are likely, with afternoon clearing. Low mixing heights and light offshore transport winds will likely make for poor ventilation conditions. 2. DISPERSION Zone 601-612 (North Coast Range and Cascades): MORNING Mixing height 2000 - 3000 ft. Transport wind SSE to SSW at 15 - 25 mph. Surface wind SE to S at 8 - 12 mph.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SUNDAY A strong southwesterly jet stream will push an active cold front onshore in the morning. Rain will increase, from west to east, across the entire region Sunday. Brisk southwesterly transport winds will decrease and veer to northwesterly, in the wake of the cold front. Post-frontal showers will be limited, mainly to the mountains, Sunday night, with the snow level only dropping to 7000 feet. OUTLOOK (MONDAY-WEDNESDAY) The flow aloft is forecast to dry out and turn northwesterly by Monday morning. Clearing skies should lead to morning surfaced-based inversions with recent rains likely leading to areas of valley fog formation. Transport winds will turn light northerly across the northern zones and northeasterly across the southern zones. That will aid in the drying of the low-level air mass and should help to clear fog from most valley locations in the afternoon. Some sunshine should provide enough heating to improve mixing, with fair afternoon smoke dispersal conditions. Strong surface-based inversions are likely Tuesday and Wednesday mornings, as the upper-level ridge moves directly over Oregon. Morning valley fog and low clouds should be more widespread with afternoon clearing. Low mixing heights and light offshore transport winds will likely make for poor smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 MONDAY The remains of Sunday's active front are well to the east on Monday. Upper level flow is nearly due west to east but there is a hint of an upper level ridge building offshore. Because of the copious recent rains, wet ground and clearing skies will give rise to extensive valley fog. A thermal trough building offshore will turn transport winds north to north-northeast. This is a dry flow and should help to dissipate any fog or low cloudiness by mid-day. Mixing heights will be high enough for smoke dispersal conditions to remain in the fair category during the afternoon. EXTENDED OUTLOOK (TUESDAY - THURSDAY) The ridge aloft continues to develop Tuesday. Initially it will be offshore but it will drift eastward to over the Pacific Northwest by afternoon. The thermal trough continues and strengthens offshore for an east to northeast transport flow most areas. However, warm air aloft and sinking air with the upper ridge will make smoke dispersal conditions poor through much of the region. By Wednesday the upper ridge axis will extend from central Nevada, through central Oregon and northward to Alberta. It will continue its eastward drift. Low level flow remains offshore but maximum mixing heights will not get very high - anticipate unfavorable burning conditions most areas for Wednesday. On Thursday the upper ridge continues its push east. Flow aloft becomes southwesterly and temperatures aloft begin to cool. This will help maximum mixing heights recover to a more favorable level. Low level flow goes onshore with a generally south or south-southwest transport winds. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 1900 - 2900 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 TUESDAY A broad ridge in the upper atmosphere covers the region on Tuesday. This ridge extends from a high centered just off the northern California coast. A surface thermal trough extends northward from California. Initially this will be offshore but should shift inland during the afternoon hours. The pattern suggests a very light east to northeast transport wind. Warm air and subsidence aloft will put a lid on mixing heights and smoke dispersal conditions will be poor to marginal many areas. EXTENDED OUTLOOK (WEDNESDAY - FRIDAY) The upper ridge drifts east and by Wednesday its axis will lie on a line from Nevada to Alberta. Low level flow will remain offshore but very light. Smoke dispersal conditions will range from poor in the northwest to fair in the southern Cascades. By Thursday the upper ridge moves east and an upper trough in the Gulf of Alaska turns flow aloft to southwesterly. A weak front approaches the northwest coast late and may provide some light rain in northwestern Oregon and the north Cascades Thursday night. Mixing heights should improve most areas. Friday the remains of the front are through, transport winds turn northerly and transport winds turn northerly. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY *** Poor Ventilation Conditions *** High pressure aloft continues over the Pacific Northwest on Wednesday, but it is moving slowly eastward. The axis of the high pressure ridge extends from Nevada to Alberta by mid morning, and by early evening has moved to the northern Rockies. The surface thermal trough that had been offshore will move onshore during the afternoon and the offshore flow of the past few days will become onshore. With uncertainty as to the time of the projected wind shift and low mixing heights Wednesday will not be a favorable day for burning. EXTENDED OUTLOOK (THURSDAY - SATURDAY) The upper level ridge will be well to the east by Thursday with southwest flow aloft setting up over the Pacific Northwest. A weak front will approach the northern Oregon coast during the afternoon but moisture appears to be very limited. There is a chance for some light rain in the extreme northern zones Thursday afternoon. Mixing heights will have recovered most areas for more favorable burning conditions. By Friday models show minor ridging aloft. Winds will be northerly, maximum mixing heights will be up and burning conditions will continue to improve. Saturday will see southwesterly flow aloft, onshore transport winds and mixing heights back into the 3500 to 4500 foot range. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 FRIDAY The upper-level flow will turn west-southwesterly, in the wake of a weak cold front that will be exiting the state. A surface ridge of high pressure will nose onshore and turn transport winds north to northeasterly. Skies will start out mostly cloudy with a chance of a shower, mainly north. Some afternoon clearing will improve mixing enough for fair smoke dispersal conditions. OUTLOOK (SATURDAY-MONDAY) The upper-level flow is forecast to turn a bit more southwesterly on Saturday, which will maintain dry conditions. Warming aloft will begin to suppress mixing heights with only marginal to fair afternoon smoke dispersal conditions. An upper-level trough is forecast to move into California on Sunday and Nevada on Monday, with a ridge amplifying over Oregon. That will continue to bring dry weather to the region with warming aloft further suppressing afternoon mixing. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SATURDAY The upper-level flow is forecast to turn southwesterly, as a splitting weak trough approaches the coastline. It will spread some clouds across the region but not likely any precipitation. Transport winds will be mostly northerly across the northern zones but likely turn onshore across the southern zones. Partly sunny skies will improve mixing enough for fair afternoon smoke dispersal conditions. OUTLOOK (SUNDAY-TUESDAY) An upper-level trough is forecast to split apart, as is moves onshore, with the main portion of it dropping southward, across California and Nevada, Sunday through Tuesday. An upper-level ridge is forecast to build over Oregon for continued dry conditions. Warming aloft will combine with October's lowering sun angle to strengthen overnight surface-based inversions. Afternoon smoke dispersal conditions will deteriorate each day, becoming marginal by Monday and poor on Tuesday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Weak upper level trough over the region today will dissipate and give way to an upper level ridge that will build into the region through early next week. Surface high pressure will build to the north with a thermal trough moving up from California. This will bring mostly northerly to offshore flow. Expect mostly sunny skies with patchy fog in the valleys during the morning. Air mass will further stabilize and with generally light wind flow, make for poor smoke dispersion. OUTLOOK (MONDAY - WEDNESDAY) Upper level ridge continues to strengthen over the state Monday and Tuesday before slowly shifting eastward on Wednesday.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 *** Poor Smoke Ventilation Conditions Through Mid-Week *** MONDAY Much of the early part of the week will dominated by a strong ridge aloft over most of the Pacific Northwest as a cut-off low meanders over southern California. Subsidence (Sinking air motion) will warm the air aloft and limit mixing heights to very low values. Monday will see generally poor smoke dispersal conditions in all zones except the southern Cascades. Winds should mostly be from the north-northeast. EXTENDED OUTLOOK (TUESDAY - THURSDAY) The ridge-to-the-north/cut-of-low-to-the-south pattern is usually a slow-to-change pattern and little day-to-day variation is expected in weather through at least Wednesday. Expect continued very low mixing heights and poor smoke dispersal conditions. Tuesday will see mostly light north to northeast winds while the winds will become more westerly on Wednesday. On Thursday the low over southern California moves east as does the upper ridge to the north. This will allow southwesterly flow aloft to develop over the eastern Pacific and the Pacific Northwest. A Pacific cold front will ride this flow to the Oregon coast by mid afternoon and some light rain will spread to the Cascades by evening. The subsidence aloft switches to rising air motion and maximum mixing heights should rise dramatically on Thursday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 *** Poor or Marginal Smoke Ventilation Conditions Continue *** TUESDAY An upper level "blocking" pattern continues with high pressure aloft over the Pacific Northwest and an upper level low spinning over the northern Baja peninsula of Mexico. This is a slow-to-change pattern and the ridge is shunting Pacific weather systems to the north of the region. Subsidence (or sinking air motion) aloft is holding mixing heights down. This, together with generally light winds, will inhibit ventilation many areas. A surface thermal trough extends from off the California coast northward to off the Oregon coast. This will give offshore flow and allow some opportunities for burning in selected problematical locations in the Coast Range. EXTENDED OUTLOOK (WEDNESDAY - FRIDAY) The upper level pattern begins a slow shift eastward on Wednesday. The thermal trough shifts inland and onshore low-level flow will develop. Transport winds most areas will be from southwest through northwest. The upper level flow goes southerly on Thursday and the region will be out of the area of strong subsidence aloft for higher afternoon mixing heights. Low level flow will continue onshore. On Friday, flow aloft will be from the southwest. Models show a weakening Pacific front moving into northwest Oregon later Friday and a stronger system following Saturday. Saturday, Sunday, and Monday will likely see widespread wetting rains most of western Oregon. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 1000 - 2000 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 *** Poor or Marginal Smoke Ventilation Conditions Continue *** WEDNESDAY A slow transition out of the sunny and dry weather pattern of the past few days begins on Wednesday - but slow is the operative word here. An upper low continues in the vicinity of southern California and a ridge of high pressure over the Pacific Northwest is shunting weather systems well to the north. The upper ridge will edge east during the day but Wednesday will be another day of hazy sunshine, low mixing heights and light transport winds. Mixing heights will be around 2000 feet or less most areas except the southern Cascades. Low level flow should switch to onshore most areas but they will remain light and somewhat variable. EXTENDED OUTLOOK (THURSDAY - SATURDAY) The upper ridge will have moved east by Thursday and an upper short wave will be approaching from the southwest. This will increase cloudiness throughout the day and by late in the afternoon some rain from an associated weakening Pacific front will reach the south coast. This will spread north and east during the evening hours, but the front is weak does not look to be a big wind or rain producer. Maximum mixing heights should be considerably improved, however. By Friday the region will be under westerly flow aloft with good onshore flow at lower levels. There will be enough moisture for areas of light rain and afternoon mixing heights will continue to increase. On Saturday an active warm front/cold front combination will approach from the west. Rain will be on the increase during the afternoon and rain will be heavy at times Saturday night. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 1000 - 1700 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 THURSDAY The strong upper-level ridge that has been over the region for the past few days will shift eastward to over the northern Rockies. The first in a series of weather systems is forecast to bring a chance of light rain to the coastline in the afternoon and over much of western Oregon in the evening. Increasing south to southwesterly transport winds and higher mixing heights will combine to improve smoke dispersal conditions to fair. OUTLOOK (FRIDAY-SUNDAY) West-southwesterly flow aloft will maintain considerable clouds across the region, but rainfall will likely be spotty and light. Further cooling aloft will continue to lift mixing heights with fair to good afternoon smoke dispersal conditions. Another weather system is forecast to spread mostly light rain across western Oregon Friday night and Saturday. Daytime smoke dispersion will remain fair to good. A strong and moisture-laden cold front is forecast to bring more significant rain to all of western Oregon Sunday, along with brisk southwesterly to westerly transport winds. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 FRIDAY The first in a series of progressively stronger weather systems will likely bring some very light rain to much of western Oregon in the early morning, with a decreasing chance of showers during the day. Rainfall totals will likely range from around one-tenth to one-quarter of an inch. Cooling aloft will lift mixing heights and south-southwesterly transport winds will provide fair to good daytime smoke dispersal conditions. OUTLOOK (SATURDAY-MONDAY) The next weather system will spread more significant rain across western Oregon Friday night and Saturday, with an additional one-half to three-quarters of an inch likely by Saturday evening. The rain should briefly let up in the afternoon with increasing south-southwesterly transport winds making for good smoke dispersal conditions. A strong warm front will renew the steady rain across western Oregon Saturday night, followed by a moisture laden cold front early Sunday morning. This system could bring another 1-2 inches of rain, especially north, along with strong southerly winds. A strong westerly jet stream, aimed right at Oregon, will continue significant shower activity Sunday afternoon through Monday, with the snow level dropping from more than 6000 feet early Sunday to below 4000 feet on Monday. Several inches of snow accumulation are likely, above 4000 feet, by Monday night. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SATURDAY The second in a series of progressively stronger weather systems will move across western Oregon in the early morning, likely dropping from around one-tenth to one-third of an inch of rain. The cold front is forecast to push east of the Cascades by late morning with the rain tapering off to a few showers. Increasing south-southwesterly transport winds and high mixing heights should make for good smoke dispersal conditions. OUTLOOK (SUNDAY-TUESDAY) A warm front will renew the steady rain across western Oregon Saturday night, followed by a strong cold front early Sunday morning. Rainfall totals from this system will likely range from around one inch to more than two inches, with the heaviest rain likely on western mountain slopes. The low pressure center is forecast to be quite intense but will remain well offshore. That will keep highly damaging winds from coming onshore, but the cold front will still produce strong southerly winds, especially over coastal areas. Gusts to around 60 mph are likely over coastal areas and sections of the coastal range in the pre-dawn hours Sunday. Blustery southerly winds will extend inland across the region Sunday. A strong westerly jet stream, aimed right at Oregon, will continue significant shower activity Sunday afternoon through Tuesday, with the snow level dropping from more than 6000 feet early Sunday to below 4000 feet Monday and Tuesday. Several inches of snow are likely, above 4000 feet north and 5000 feet south, Monday and Tuesday. Rain and mountain snow showers are forecast to taper off late Tuesday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SUNDAY Wet and windy weather is in store for all of Oregon on Sunday. A warm front will renew the steady rain across western Oregon tonight (Saturday night). The third, and strongest, in a series of cold fronts will come onshore early Sunday morning and sweep across the entire state by evening. Rainfall totals from this system will likely range from around one inch to more than two inches across western Oregon, with the heaviest rain likely on western mountain slopes. The low-pressure center is forecast to become quite intense but track well to the northwest, to near the northern tip of Vancouver Island, British Columbia, by Sunday night. The trailing cold front will bring strong southerly winds to all of Oregon. Gusts to 60 mph are possible for coastal areas, with sections of the coast range and higher elevations of the Cascades likely getting gusts over 50 mph. Gusts to near 40 mph are likely across the inland valleys. In the wake of the cold front, blustery winds will likely turn more southwesterly. Showers will be frequent with a slight chance of thunderstorms. Snow levels will rapidly drop, with accumulating snow likely, above 4000 feet north and 4500 feet south, Sunday night. South-southwesterly transport winds and high mixing heights will provide good smoke dispersal conditions. OUTLOOK (MONDAY-WEDNESDAY) A strong westerly jet stream, aimed right at Oregon, will continue significant shower activity Monday and Tuesday, with additional snowfall likely above 4000 feet north and 4500 feet south. Rain and mountain snow showers are forecast to taper off late Tuesday, as the flow aloft turns northwesterly and more stable. A weak and transitory upper-level ridge should bring one dry day, on Wednesday, with warming aloft lowering mixing heights. Smoke dispersal conditions should remain good on Monday and then deteriorate to fair on Tuesday and marginal on Wednesday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 MONDAY A 180 mph jet stream remains aimed directly at Oregon on Monday. Sunday's wet and windy storm will be well to the east of the region, but showers and possible thunderstorms will linger. Cool air aloft will allow for high mixing heights and good smoke dispersal conditions most areas. Snow levels will range from about 4000 feet in the north to about 4500 feet in the south. EXTENDED OUTLOOK (TUESDAY - THURSDAY) The upper level jet slackens and drops southward while weak high pressure aloft begins to build over the eastern Pacific on Wednesday. Showers are still in the forecast, mainly early in the day. Snow levels could drop as low as 3000 feet in the north. Mixing heights will remain high most areas except the southern Cascades. By Wednesday the upper level ridge moves over the Pacific Northwest and an upper low develops about 450 miles west of the Washington Coast. Low level flow goes south or southeasterly. Subsidence aloft (sinking air motion) suppresses maximum mixing heights and smoke dispersal conditions become marginal most areas. On Thursday the center of the upper low moves to within about 250 miles of the northern Oregon Coast. Upper flow becomes southwesterly over the region. A Pacific weather system moves into Washington and Oregon during the day. Rain reaches western Oregon early in the morning, but rainfall totals do not look particularly high at this point. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 TUESDAY The main jet stream is to the south of the region on Monday, cutting across the coastline near San Francisco. There will be some lingering showers with a snow level occasionally dropping to around 3500 feet. Expect generally westerly transport winds to continue and smoke dispersal conditions will be fair to good most areas except just fair in the southern Cascades. EXTENDED OUTLOOK (WEDNESDAY - FRIDAY) A developing upper level low offshore helps build high pressure aloft over the Pacific Northwest. Subsidence and warming aloft will limit maximum mixing heights. Weather should be dry Wednesday and low level flow will be offshore. Look for mostly easterly transport winds for coastal zones and southeasterly transports for the Cascades. Ventilation conditions will only be marginal. On Thursday the offshore low moves to within about 250 miles of the northern California coast. Upper level flow backs to southwesterly over the region. Some light rain spreads in during the early morning hours, but at this point it looks like amounts will mainly be less than about a quarter of an inch. Transport winds shift to southerly and maximum mixing heights recover to the 3-4000 foot range for improving ventilation conditions. On Friday the upper low slides into California. Periods of light rain continue west of the Cascades, southerly transport winds and mixing heights climbing to 4500 feet or above will make for good smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY A ridge of high pressure in the upper atmosphere covers the Pacific Northwest on Wednesday but an upper level low is also intensifying about 450 miles west of Brookings. Skies will be partly cloudy but increase during the afternoon. Transport winds will be generally offshore from the southeast or east. Mixing heights will be somewhat suppressed during the day. Rain will reach the southwest coast by evening and spread north and east overnight. EXTENDED OUTLOOK (THURSDAY - SATURDAY) The upper level low moves to about 400 miles west of San Francisco on Thursday. Upper flow over Oregon backs to southwesterly. Rain falls throughout the day most areas but amounts will be around a third of an inch. Freezing levels push to around 8-9000 feet. Southerly through easterly transport winds will be the rule. On Friday the upper level low drops southward to off the southern California coast. Very limited moisture remains over the Pacific Northwest for mostly dry conditions. Smoke dispersal conditions remain marginal but the easterly or offshore component continues at low levels to present burn opportunities not normally available with the prevailing southwesterlys this time of year. On Saturday the upper low opens up and moves northeast as a weak upper level trough. Smoke dispersal conditions will improve and transport winds will shift to southerly. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 THURSDAY The transitory upper-level ridge that was over the region on Wednesday is forecast to rapidly shift eastward to over the northern Rockies. An approaching upper-level trough is digging southward offshore and is forecast to be centered about 300 miles west of the northern California coast by Thursday afternoon. A moist south-southwesterly flow aloft will spread rain across the region during the day. Rainfall totals will likely range from one-quarter to three-quarters of an inch, with the greatest totals in the south and west. The snow level will rise to 5500 feet north and 6500 feet south. Transport winds will be mostly south to southeasterly with fair smoke dispersal conditions. OUTLOOK (FRIDAY-SUNDAY) The upper-level trough will continue digging southward Friday, with the center of circulation forecast to be just off the central and southern California coastline by Friday evening. Skies will likely remain mostly cloudy, but rain will taper off from north to south. Additional rainfall totals will be around one-tenth of an inch or less with the greatest amounts in the south. Transport winds will become south to east and weaken with continued fair smoke dispersal conditions. An upstream trough will act as a kicker system and eject the California eastward on Saturday. The flow aloft is forecast to be southwesterly with transport winds turning mostly southerly and increasing. Smoke dispersal conditions will remain fair with rain likely advancing onshore by Saturday evening. A weak cold front is forecast to bring more rain to western Oregon Saturday night and Sunday morning with showers tapering off Sunday afternoon.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SATURDAY The upper-level trough that was centered just off the California coast on Friday will weaken and slide inland across California and Nevada. Western Oregon will start the day between storms with stable conditions and areas of valley fog. The next weather system, in a moist southwesterly flow aloft, will spread rain back across the region, from west to east, during the afternoon and evening. Mixing will improve in the afternoon with increasing south to southwesterly transport winds creating fair smoke dispersal conditions. OUTLOOK (SUNDAY-TUESDAY) A Pacific cold front will bring rain to most of the region through Sunday morning. Rainfall totals will generally range from one-quarter to three-quarters of an inch, with greater amounts possible in the northern mountains. Snow levels will only drop to around 5000 feet north and 6000 feet south. Smoke dispersion will be fair to good. Showers will taper off Sunday afternoon, but a rapidly approaching warm front will spread clouds back across northwestern areas Sunday night. The warm front will likely bring some rain northern zones on Monday, while southern zones stay dry. Snow levels will lift to above 8000 feet. Increasing southerly transport winds should make for fair some dispersal conditions north, but southern zones could become stagnant with more persistent valley fog. A strong upper-level ridge is forecast to build over the region, on Tuesday, pushing the warm-frontal rain north of Oregon. Stagnant conditions will advance northward across the region. Valley fog should become more widespread with possible persistent surface-based inversions. Light southeasterly transport winds and low mixing heights will generally make for poor smoke dispersal conditions. Some ridges could get above the low-level temperature inversions in the afternoon. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 1000 - 2000 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SUNDAY A Pacific cold front will bring rain to most of the region Saturday night through the pre-dawn hours Sunday, with showers tapering off during the day. Rainfall totals will generally range from one-quarter to three-quarters of an inch, with the greatest amounts at higher elevations. Snow levels will only drop to around 5000 feet north and 6000 feet south. Smoke dispersion will be fair to ghould. OUTLOOK (MONDAY-WEDNESDAY) An intense storm system is forecast to develop, in the western Gulf of Alaska, by Monday. An associated warm front will spread clouds, and possibly light rain, back over northwestern zones. Southern zones should stay dry. Snow levels will lift to above 8000 feet. Brisk southerly transport winds should make for fair to good smoke dispersal conditions north, but lighter winds will result in only marginal to fair smoke dispersal conditions south. A strong upper-level ridge is forecast to build over the region Tuesday and Wednesday. The warm-frontal rain should get displaced north of Oregon. More stagnant conditions will advance northward across the region. Valley fog should become more widespread with possible persistent surface-based inversions. Transport winds will slacken and turn offshore. Low mixing heights will generally make for marginal to poor smoke dispersal conditions. Smoke from higher ridges could possibly raise above surface-based inversions into light southerly transport winds. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 MONDAY On Monday a ridge in the upper atmosphere will extend from southern California to the northern Rockies and an upper level low will be centered in the Gulf of Alaska. Winds around these two features will leave the Pacific Northwest in a southwesterly flow aloft. A Pacific cold front nearly parallel to the flow will slowly move into the Pacific Northwest. Rain will reach Washington overnight, then northwestern Oregon by morning. The rain will slowly spread southward but precipitation totals will taper off from north to south. Heaviest rain will be in Washington. Northwest Oregon should see between one-half to three-quarters of an inch while southwest Oregon will find anything from nothing to perhaps as much as a tenth of an inch by Tuesday morning. Maximum mixing heights will mostly be in the 3-4000 foot range and brisk south to south-southwesterly transport winds should make for generally fair smoke dispersal conditions. EXTENDED OUTLOOK (TUESDAY - THURSDAY) *** Marginal to Poor Ventilation Conditions after Monday *** The low in the Gulf deepens and the ridge over the western US expands for dry weather through the middle part of the week. Transport winds will shift to light offshore Tuesday and Wednesday. On Thursday transport winds will go light and variable in the north and light southwesterly in the south. Mixing heights through the outlook period will have difficulty getting above 2000 feet most areas for marginal to poor ventilation conditions. 2.
