DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 THURSDAY A weak upper disturbance moves across the region. Skies will be cloudy with a few showers north, while more significant and steady rain continues in the south. The snow level will be around 3000 feet. Transport winds will be generally south-southwesterly in the north and northwesterly in the south. The atmosphere will be fairly stable and smoke dispersal conditions will be marginal in the coast range and poor in the Cascades. EXTENDED OUTLOOK (FRIDAY - SUNDAY) An upper low in the Gulf of Alaska drops southeast to a position about 500 miles off the Oregon coast Thursday. This will induce a ridge over the Pacific Northwest. Weather will be generally dry west of the cascades, but the atmosphere will again be very stable. Expect poor ventilation conditions with best ventilation over the southern coast range. On Friday the upper low moves to about 600 miles west of San Francisco, California. The ridge axis shifts east and this will allow the low to spread some moisture northward from California and Nevada. Precipitation amounts should be very light, but the atmosphere will remain stable and ventilation conditions remain poor. The remains of the upper low move closer to the California coast on Saturday. Upper flow over the Pacific Northwest goes to nearly due southerly. With warm air aloft and plenty of cloud cover and low sun angle for minimal surface heating, maximum mixing heights remain low and most of the region will experience poor ventilation conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 FRIDAY Upper air charts show a deep and compact low developing about 500 miles offshore on Friday. This will pump up a weak ridge over the Pacific Northwest giving dry weather but a very stable atmosphere. Atmospheric ventilation conditions will be generally marginal. Transport winds will have an easterly component, however, allowing for some burn opportunities that don't occur with the prevailing west or southwesterly flow this time of year. EXTENDED OUTLOOK (SATURDAY - MONDAY) The upper low moves to about 600 miles west of San Francisco Saturday and winds aloft back to a more southerly direction. This brings some light rain northward from California and Nevada. Amounts will be light and confined mainly to southwestern Oregon. Ventilation conditions remain poor, but again, an easterly component to transport winds may present some burn opportunities. On Sunday the upper low off the California coast weakens, upper flow continues southerly and ventilation conditions remain poor to marginal. Expect little change for Monday. 2.

Today's forecast will include instructions for both Saturday and Sunday. Please call this afternoon if you want to seek waivers from today's instruction for the weekend.*** 1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level ridge will continue to build over the state tomorrow as an upper level low digs to the south several hundred miles to the west and southwest of the state. Southerly flow aloft will stream some mid and high clouds into the region bringing a risk of a few sprinkles. Otherwise, expect mostly dry and fair conditions with some patchy fog in the valleys during the morning hours. Air mass will be stable but decent offshore flow will provide burning opportunities in the Coast Range. OUTLOOK (SUNDAY - TUESDAY) Upper level low drops southward to just off the southern California coast and will continue to stream clouds over the state with a continued chance of light showers. Upper ridge gradually moves to the east. Air mass will remain stable with continued offshore flow. This low gradually dissipates Sunday and Monday but another low moves in to the west of the state by Monday. Air mass will remain stable and will also dry out some. Low will move closer by Tuesday to bring a front just offshore and increase the chance of moisture during the afternoon and evening. Wind flow will increase from the SE to S and improve mixing and smoke dispersion. 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 Upper air charts show a strong low about 900 miles west of Oregon and a broad upper level ridge over the western plains states. In between a well defined upper disturbance is moving from SW to NE over the state. There is some moisture associated with this disturbance and there are areas of precipitation western Oregon and the Cascades. Freezing levels this morning were quite high although a cold surface high east of the Cascades is keeping snow a possibility down to pass levels in the mountains. Radar this morning shows most of the precipitation is in the northern Cascades and northern Willamette Valley or over northeastern California.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 TUESDAY Upper air charts show a deep low pressure circulation centered about 750 miles west of Oregon on Tuesday. An upper ridge lies along a line from Nevada through northern Idaho. A Pacific frontal system will rotate around the offshore low. Light rain from a weak warm front will move south to north early in the day but precipitation amounts will be light. A trailing cold front will push into coastal areas late Tuesday then inland overnight for more significant precipitation. Transport winds will be a brisk south to south-southeast and ventilation conditions should be generally fair. EXTENDED OUTLOOK (WEDNESDAY - FRIDAY) The upper low rotates into the northern Gulf of Alaska on Wednesday and flow over the region veers to more southwesterly. Mixing heights generally improve slightly for fair to good smoke dispersal conditions most areas. On Thursday warmer air aloft stabilizes the atmosphere and ventilation conditions deteriorate to marginal to fair. Expect little change for Friday although mixing heights may be slightly better than on Thursday. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 3500 - 4500 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY A low pressure area aloft will be centered about 400 miles west of the northern tip of Vancouver Island on Wednesday. Upper level flow will be generally southwesterly across the region. A cold front very early in the day will leave between a quarter and a half of an inch of rain on the ground, but as the front pushes east only scattered showers are likely in the cool unstable air mass behind the front. The instability should give mostly fair smoke dispersal conditions to the area, and transport winds winds will be mostly south-southwesterly. EXTENDED OUTLOOK (THURSDAY - SATURDAY) On Thursday upper flow veers to more westerly. The air mass will slowly stabilize during the outlook period leading to deteriorating ventilation conditions. Expect a few showers Thursday and still generally fair smoke dispersal conditions. For Friday just scattered showers and marginal to fair ventilation. Winds will start out westerly and become south to southwesterly during the day. An approaching warm front Saturday will bring rain, but the warm air streaming in aloft with this system will accelerate the stabilization of the atmosphere and maximum mixing heights will be quite low and ventilation poor. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 THURSDAY An embedded upper-air disturbance, in a strong westerly flow aloft, will increase the shower activity across western Oregon in the afternoon and evening. Precipitation totals will range from around one-quarter of an inch, in the southern valleys, to more than an inch over the northern mountains. Accumulating snow is likely above 4000 feet north and 5000 feet south. Ventilation conditions should be fair to good with south to southwesterly transport winds. OUTLOOK (FRIDAY-SUNDAY) The air mass will begin to stabilize by late Friday, as the flow aloft veers to northwesterly. Showers will begin to decrease in the afternoon. Transport winds will veer to more westerly. Smoke dispersal conditions should remain fair to good through Friday afternoon, but mixing heights will drop sharply in the evening. A strong warm front will spread significant rainfall back across western Oregon Saturday, mainly north, with the snow level rising to 6000 feet north and 8000 feet south. The combination of possibly heavy rainfall and rising snow levels may lead to areas of flooding north. Increasing southeasterly to southerly transport winds will turn southerly south of the warm front across the southern zones in the afternoon. North of the warm front, smoke dispersal conditions will likely be marginal to poor, due to warm air aloft. However, south of the warm front, balmy southerly winds will help to warm surface temperatures and improve ventilation conditions to fair. The strong warm front should push north of the region by Sunday morning, with the rainfall tapering off. Southerly surface and transport winds will make for unseasonably mild conditions. The freezing level will rise to above 7000 north and to near 9000 feet south. Warm air aloft will suppress mixing heights, and lighter transport winds will make for marginal to poor ventilation conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 FRIDAY A strong westerly flow aloft will continue to circulate bands of showers across western Oregon. The air mass will begin to stabilize in the afternoon, as the upper-level winds veer to northwesterly. Showers will briefly taper off in the evening. West-southwesterly transport winds will also decrease in the evening. Smoke dispersal conditions should remain fair to good during the day, but mixing heights will drop sharply in the evening. OUTLOOK (SATURDAY-MONDAY) A strong warm front will spread significant rainfall, from south to north, across western Oregon early Saturday morning. Rain could become heavy by late-morning, with the main area of rain shifting to over the northern zones in the afternoon. The snow level will start out near 4000 feet north and 6000 feet south but rapidly rise to 6000 feet north and to above 8000 feet south in the afternoon. The combination of locally heavy rainfall and rising snow levels may lead to areas of flooding, especially along the northern coastal rivers. Increasing south to southeasterly transport winds will turn south-southwesterly on the south side of the warm front, across the southern zones, in the afternoon. North of the warm front, smoke dispersal conditions will likely be marginal to poor. South of the warm front, across the southwestern zones, warmer surface winds will promote better afternoon mixing with fair smoke dispersion. The strong warm front should push north of the state by Sunday morning, with the rainfall tapering off. Sunday should be mostly dry with the freezing level rising to near 10,000 feet. South to southwesterly winds will make for unseasonably mild conditions with some clearing. Smoke dispersion should be fair. The break from the wet weather will be short-lived, with the cold front forecast to come onshore Monday morning and spread rain back across the region by Monday afternoon. Snow levels will remain quite high early and then drop to around 6000 feet north and 7000 feet south by evening. Smoke dispersal conditions will improve to fair to good with continued south to southwesterly transport winds. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SATURDAY A strong warm front will spread significant rainfall northward, across western Oregon, beginning in the pre-dawn hours. The front is forecast to move across southwestern Oregon in the morning and continue northward, across the central zones, during the afternoon. The front is forecast to push into Washington by early Sunday. Rainfall will likely become heavy by late-morning, as the main area of rain slowly migrates northward. 1-3 inches of rain are possible over the southern mountains and in the Cascades, with one-quarter to one inch likely in the southern valleys. Hardest hit will be the northern coastal mountains, where 3-6 inches of rain are possible. Northern valleys could see 1-3 inches of rain. The snow level will start out near 4000 feet north and 6000 feet south but rapidly rise to 6000 feet north and above 8000 feet south by midday. North of the warm front, mixing heights will be low with heavy rain, marginal to poor smoke dispersion, and south to southeasterly transport winds. Rain will taper off south of the front, with transport winds turning more southwesterly and smoke dispersal conditions improving. The combination of locally heavy rainfall and rising snow levels will lead to areas of flooding, especially along the northern coastal rivers. OUTLOOK (SUNDAY-TUESDAY) The strong warm front should push north of the state by Sunday morning, with the rainfall tapering off. Central and southern zones may stay mostly dry, while northwestern zones continue to pick up some light rainfall. The freezing level will rise to near 10,000 feet with balmy surface temperatures. Smoke dispersion should be fair with south to southwesterly transport winds. The break from the wet weather will be short-lived, with the related cold front forecast to drop southeastward into northwestern Oregon Sunday night and across the remainder of western Oregon Monday. Snow levels will remain quite high through Monday morning, and then drop to around 5000 feet north and 7000 feet south by evening. Afternoon smoke dispersal conditions should be fair to good with continued south to southwesterly transport winds. Another strong cold front is forecast to bring more rain and wind on Tuesday with snow levels lowering to 3000 north and 4000 feet south. Smoke dispersal conditions should be good with brisk southwesterly transport winds. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 TUESDAY A strong Pacific front will move through western Oregon overnight Monday night. Expect gusty winds and heavy rain with the front and lowering snow levels behind. Rainfall amounts of around an inch are likely by Tuesday morning. Precipitation will decrease during the afternoon, but by evening snow levels will drop to about 2000 feet in the north and about 2500 feet in the south. High mixing heights will allow for fair to good smoke dispersal conditions most areas. OUTLOOK (WEDNESDAY - FRIDAY) Upper flow becomes westerly on Wednesday. Rain and snow will continue but amounts will be light. The snow level will be near 1000 feet in the morning rising to about 3000 feet in the afternoon. Some stabilization of the atmosphere will occur limiting mixing heights but ventilation conditions should remain fair to good. By Thursday precipitation will be limited to extreme northwest Oregon, the air mass will stabilize and smoke dispersal conditions become marginal. On Friday a disturbance moving from the southwest brings renewed precipitation to the region but also improving ventilation conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY Upper air charts show a generally west to east flow with a minor upper level disturbance moving through the region during the afternoon. This will produce showers but precipitation amounts should be light, generally less than a quarter of an inch. The snow level will be quite low, especially in the morning. Precipitation will fall as snow down to about 1500 feet. Expect brisk southerly transport winds and generally fair smoke dispersal conditions throughout western Oregon. OUTLOOK (THURSDAY - SATURDAY) An upper level ridge passes over the area early in the day on Thursday. This will help stabilize the atmosphere although showers are still possible in extreme northern Oregon. Precipitation amounts will be light. Smoke dispersal conditions will be marginal in the north but fair in the south. The upper ridge stalls to the east on Friday and low level flow will have an easterly component. Transport winds will be mostly south to southeast. Ventilation will be marginal except fair along the south coast. By Saturday a broad upper low will develop about 450 miles west of the coastline. This will push surges of moisture into the region from the southwest. There is a potential for another surge of significant rain and windy conditions Saturday and Sunday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 THURSDAY A weak and transitory upper-level ridge will slide across Oregon during the day. Slight warming aloft will stabilize the atmosphere with only a slight chance of showers, mainly over the mountains. The snow level will lift to 2500 feet north and 3500 feet south in the afternoon. Afternoon smoke dispersal conditions will be marginal to fair with transport winds backing to the SSE. OUTLOOK (FRIDAY-SUNDAY) The upper-level ridge is forecast to stall over eastern Oregon and western Idaho on Friday, as a strong upper-level trough develops about 1000 miles west of the Washington and Oregon coast. Increasing low-level offshore flow will help delay the onset of moisture from a strengthening westerly flow aloft. Smoke dispersal conditions will remain marginal to fair. A strong frontal system will spread rain and mountain snow back across the region by Friday night with snow levels ranging from near 1500 feet north to around 3000 feet south. A strong cold is forecast to bring rain, mountain snow, and brisk winds to much of western Oregon Saturday morning. Transport winds should become mostly southerly by Saturday afternoon with a strong west-southwesterly jet stream directing vigorous showers, and possibly thunderstorms, onshore. Snow levels will range from near 2500 feet north to 4000 feet south. Smoke dispersal conditions should be fair to good. By Sunday, the parent upper-level though is forecast to progress eastward, to about 600 miles off the coastline, and continue to circulate abundant moisture across Oregon. A strong southwesterly jet stream, extending from the southern Oregon coast to over central Idaho, will slowly sag southward, to over northern California. That will put Oregon on the cold side of the jet stream, with snow levels dropping to 1500 feet north and 2500 feet south by Sunday evening. Smoke dispersal conditions should remain fair to good with mostly south to southwesterly transport winds. 2.
