DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 An upper level low sets up about 200 miles west of Waldport, Oregon giving south to southwest flow aloft. An upper short wave in this flow sill bring showers mainly to southwestern Oregon with those showers moving northward during the evening hours. OUTLOOK (THURSDAY - SATURDAY) On Thursday the upper low backs off and moves west, farther off the coast. The upper short wave will rotate out of the state into Washington early in the morning leaving the region dry with a southerly flow aloft. Expect good mixing heights and good burning conditions most areas. On Friday the upper low continues off the coast with another weak short wave moving northward across the region producing scattered showers. On Saturday a front develops offshore and moves to the northern coast late in the afternoon. Elsewhere expect dry weather with strong southerly transport winds and mixing heights high enough for good smoke dispersal conditions. OUTLOOK (THURSDAY - SATURDAY) 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Big low center aloft in the Gulf of Alaska. However, this is far enough to the west to allow higher pressure to build over the Pacific Northwest and stabilize the air mass a bit. As a result, mixing height is held down a bit over western Oregon. Low is close enough to result in southerly low-level wind flow, although the speed is fairly light. Combination of light transport and restricted mixing results in fair to good dispersion during the afternoon but marginal dispersion for the rest of the day. OUTLOOK (MONDAY - WEDNESDAY) Upper low develops a sharp trough that moves toward the coast and finally cuts off a closed low center over northern California. Precipitation returns to the area, reaching the coast after noon on Monday. Rain spreads across the area Monday night and Tuesday. Freezing level drops as the system moves east, so rain likely to change to snow at the higher elevations by Tuesday morning. Transport southerly, turning west to northwest as the trough passes. Mixing improves temporarily with the passage of the trough but the air mass stabilizes quickly behind this system. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper air charts show a major trough in the eastern Pacific on Monday. Flow aloft over the region is southerly ahead of a slow moving Pacific cold front. Rain arrives during the afternoon spreading eastward from the coast to the Cascades. Mixing height will allow for fair to good smoke dispersal conditions but transport winds will become variable later in the day after starting out mostly southerly. OUTLOOK (TUESDAY-THURSDAY) On Tuesday the upper trough slowly moves through the region, eventually splitting with the southern portion becoming a closed upper low over California. Showers will continue over the area and smoke dispersal conditions should be fair to good with some stabilization of the atmosphere. Transport winds will be generally northwesterly. On Wednesday the upper low drifts across southern Nevada. Flow aloft will be light and variable but brisk northwesterly transport winds are likely closer to the ground. On Thursday weak ridging develops over the eastern Pacific Ocean. Flow aloft will be from the north or northwest, and while there will still be a few showers around expect a drying trend during the day. Smoke dispersal conditions should be good. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 The Pacific cold front that moves through Monday night brings cooler air and precipitation to the region. Snow level will drop to 4500 feet by afternoon and continue to drop Tuesday night. Transport winds will be generally northwesterly and mixing heights will provide for fair to good smoke dispersal conditions. OUTLOOK (WEDNESDAY-FRIDAY) On Wednesday surface high pressure builds into the eastern Pacific. Showers will be confined mostly to the Cascades but the air mass will remain cool with snow levels Wednesday morning down to about 2500 feet. A lingering shower or two is still possible Thursday but temperatures will be a bit warmer. Transport winds will again be generally northerly or northwesterly with good smoke dispersal conditions. By Friday expect upper ridging over the region for dry weather but suppressed mixing heights keep smoke dispersal conditions only fair. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 MONDAY The upper ridge that brought sunshine to much of the state Sunday moves east and an upper trough rotates into the Pacific Northwest during the day. A surface cold front reaches the coastline during the day. Precipitation will begin on the coast late in the morning and slowly spread eastward reaching the Cascades by evening. Expect strong southeasterly to southerly transport winds and high mixing heights for good smoke dispersal conditions. OUTLOOK (TUESDAY-THURSDAY) The upper trough continues on an axis from south of Kodiak, Alaska to northwestern Nevada on Tuesday. Showers continue during the day and maximum mixing heights remain generally above 5000 feet for good smoke dispersal conditions. By Wednesday the upper trough splits and a portion moves east. Minor ridging develops aloft, but not enough to end the showers. Maximum mixing heights climb to over 4000 feet for continued good smoke dispersal conditions. Thursday sees southwesterly flow aloft with a minor disturbance embedded in that flow moving toward the Pacific Northwest. A surface low develops and moves onshore during the day. The exact track of that low will determine transport wind directions. However, cool air aloft will keep mixing heights high. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 FRIDAY A strong northwesterly flow aloft will begin to dry things out, but the air mass will remain unstable enough for daytime heating to trigger a few showers...mainly over the northern mountains. Snow levels will start out near 3000 feet and rise to around 3500-4000 feet in the afternoon. Surface temperatures will remain well below normal. Maximum mixing heights will rise above 5000 feet for good afternoon smoke dispersal conditions OUTLOOK (SATURDAY-MONDAY) An upper-level ridge will build closer to the coastline Saturday and Sunday, with slowly weakening northwesterly flow aloft and onshore flow at the surface. There is only a slight chance of an afternoon shower, mainly over the northern mountains, on Saturday. A weak warm front will likely bring some clouds and perhaps some sprinkles to the northern zones Sunday. Early morning mixing will be poor, but daytime heating and continued strong onshore flow should provide fair to good afternoon smoke dispersion Saturday and fair smoke dispersion on Sunday. The snow level will slowly rise to about 5-6000 feet, by Sunday afternoon, with surface temperatures recovering to near normal.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SATURDAY A cool northwesterly flow aloft will direct a weak weather system across Washington and Oregon. Skies will be mostly cloudy with light morning rain in the northern zones and a chance of showers in the southern zones. Some drying is expected late in the day. Snow levels will stay near just 4000 feet. Surface temperatures will remain well below normal. The weak cold front should keep the atmosphere well-mixed in the early morning. Maximum mixing heights will rise above 5000 feet for good afternoon smoke dispersal conditions OUTLOOK (SUNDAY-TUESDAY) An upper-level ridge will build closer to the coastline Sunday, with weakening northwesterly flow aloft and onshore flow at the surface. A weak warm front will likely bring some clouds and perhaps some sprinkles to the extreme northern zones Sunday. A stabilizing air mass may create poor early morning mixing, but daytime heating should provide fair to good smoke dispersion, by Sunday afternoon, with the snow level slowly rising to about 6000 feet. Surface temperatures should recover to near normal. A cold front is forecast to bring more rain and mountain snow Monday, with snow levels dropping to 4000 feet Monday afternoon. Tuesday looks very cool and unstable with numerous showers and a good chance of afternoon thunderstorms. Smoke dispersal should be good both afternoons, but temperatures will be unseasonably cool with strong onshore flow. The snow level could drop to around 2000 feet on Tuesday. 2.
