DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 Upper air forecast charts show a low continuing off the coast of California on Tuesday. Counter-clockwise flow around that low will again bring moisture northward for areas of afternoon and evening thunderstorms. Low level flow will be generally north-northwest to north-northeast. Mixing heights will be high and smoke dispersal conditions should be good. OUTLOOK (WEDNESDAY-FRIDAY) The upper level low moves a little closer to the California coastline Wednesday but the net change on Oregon will be nil. Continued moisture and afternoon heating will pop thunderstorms again on Wednesday. Low level winds will be generally northerly and smoke dispersal conditions will remain good. On Thursday the upper low will move slightly south and upper flow over Oregon will begin to transition to northeasterly. Thunderstorms will continue, but northern sections will be less vulnerable. Transport winds will be variable. The low moves to central California by Friday but thunderstorms will continue. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 A very slow moving upper level low pressure area remains off the California coast on Wednesday. Counter-clockwise flow around that low will again spread moisture northward into Oregon. Daytime heating will destabilize the atmosphere and thunderstorms will again be a possibility. Best chance afternoons and evenings over mountainous areas. Low level flow will be southerly, switching to southwesterly in the north. Southern zones will see southwesterly winds switching to northwesterly. Mixing heights will be high enough to provide for marginal to fair smoke dispersal conditions in coastal sections and good conditions in the Cascades. OUTLOOK (THURSDAY - SATURDAY) The upper level low finally moves into California with flow aloft becoming more easterly or northeasterly over the state on Thursday. The atmosphere will still be unstable and there will still be moisture available for thunderstorms. The greatest threat of thunderstorms will be in southern sections. Smoke dispersal conditions will be about the same as on Wednesday. By Friday the upper low will be over central California with a dryer flow aloft. The threat for afternoon and evening thunderstorms continues. Winds will be generally west-northwest. By Saturday upper flow goes more northerly. The slow moving upper low drifts into Nevada and another upper low forms in Alberta. The atmosphere will remain a bit unstable, but with diminished moisture the threat of thunderstorms decreases considerably but smoke dispersal conditions remain favorable. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level low will gradually dissipate today and move to the east. Showers will be on the decrease this afternoon and evening. Upper level flow will then turn more northerly as a trough moves down from Canada. Low level flow will maintain an onshore flow. Expect mostly cloudy skies with a chance of some light showers on Saturday. Air mass will be mostly unstable and with modest onshore flow, will make for fair to good smoke dispersion. OUTLOOK (SUNDAY - TUESDAY) Upper level flow turns NW'erly Sunday and Monday with low level flow light but favoring onshore flow. Expect mostly fair skies with some morning low clouds but clearing during the day. Another trough develops off the coast later Monday and moves in late Monday to early Tuesday, bringing an increased chance of moisture Tuesday. Air mass, which stabilizes some on Sunday and Monday, will destabilize again Tuesday. Smoke dispersion will be mostly fair Sunday and Monday, improving on Tuesday. 2.

OUTLOOK (MONDAY - WEDNESDAY) Upper level flow becomes rather non-descript over the extended period with light flow both near the surface and aloft. A weak trough appears to move in Tuesday increasing the chance of showers but mainly over the mountains. Air mass will stabilize more during the night and morning hours but destabilize during the afternoon. Smoke dispersion will remain mostly fair to good. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 A network outage at the state data center precluded me from seeing any weather data up until just before forecast time. Thus this is a hurried forecast with low confidence. An upper low over southern Alberta will move slowly east early in the week. Another upper trough of low pressure will push onshore from the west into the Pacific Northwest by mid week. Mixing heights appear favorable for good smoke dispersal conditions during the afternoons. Winds will tend to onshore. OUTLOOK (TUESDAY - THURSDAY) Computer models indicate a split flow through the outlook period, but there are model differences on key features. Expect an onshore flow, decent mixing heights, and a slight chance of rain each day. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 2900 - 3900 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 An upper low over southern Alberta and Saskatchewan is moving slowly eastward. In its wake a rather ill-defined upper flow over the Pacific Northwest. Thus no extremes of weather are expected. Low level flow will be generally onshore. Temperatures should be near seasonal averages and there is a slight chance of an afternoon shower developing, otherwise expect generally partly cloudy skies. Mixing heights will allow for good smoke dispersion. OUTLOOK (WEDNESDAY - FRIDAY) As the Canadian upper low moves east another, weak and ill defined, upper low develops off the coast. Low level flow will remain onshore for temperatures remaining near average. Late in the week the upper low becomes more organized and upper flow across the region becomes generally southwesterly. There is a very slight chance of a shower each day. Transport winds should be generally onshore, and mixing heights should provide fair to good smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Pesky upper level low finally weakens and opens up into a minor trough for Sunday. This will mean less shower and thundershower activity that has plagued the state the last several days. Expect less cloud cover and slightly warmer temperatures. Air mass will remain mostly unstable and wind flow light, thus leading to continued fair to good smoke dispersion. OUTLOOK (MONDAY - WEDNESDAY) Weak upper level trough remains off the coast Monday but drifts to the south, leaving the region under a split flow for Tuesday. A minor trough will move through later Tuesday to Wednesday and bring a modest marine push to the region. Expect mostly sunny skies and warm temperatures Monday and Tuesday. Marine push will likely bring some cloud cover into the western interior on Wednesday. Air mass will stabilize more during the night and morning hours but destabilize pretty well during the afternoon. Smoke dispersion will remain mostly fair, and then improve Wednesday under the marine air. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 The Pacific Northwest seems to be stuck in a pattern of persistent troughiness. The upper trough that was over the region Sunday will drift east and another weak upper trough will approach from the west. This will keep the atmosphere unstable and keep the chance for a shower or two in the forecast. The instability will provide for good mixing heights and smoke dispersal conditions should be generally good. Low level flow will be onshore limiting burning opportunities near coast range corridors leading to the Willamette Valley. OUTLOOK (TUESDAY - THURSDAY) Upper level flow finally consolidates during the day on Tuesday with a westerly flow aloft developing. The atmosphere stabilizes somewhat although smoke dispersal conditions should still be in the fair to good category. Low level flow will remain generally onshore (westerly or northwesterly) throughout the outlook period. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 The upper trough that has been over the area finally moves east but another, minor, upper disturbance moves into southern British Columbia and western Washington tomorrow. I anticipate little, if any, precipitation from this system. On the other hand, continued instability may be enough to touch off an afternoon shower or thunderstorm over the southern Cascades on Tuesday. Mixing heights should remain favorable for fair to good smoke dispersal, but a generally westerly transport flow will limit opportunities in the coast range and especially near corridors leading to the Willamette Valley. OUTLOOK (WEDNESDAY - FRIDAY) As a generally west-to-east flow sets up aloft a minor ridge of high pressure moves through the region Wednesday and Thursday. Mixing heights remain fairly high and smoke dispersal conditions remain fair to good. Transport winds stay generally westerly. Mixing heights are suppressed somewhat by Friday but fair to good smoke dispersal conditions will continue during the afternoons. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper flow over the Pacific Northwest will be generally from the west or northwest during the day on Wednesday. A weak surface ridge axis to the west, over the Pacific, will give onshore flow, with generally northwesterly transport winds during the day. Mixing heights will be high enough to give fair to good smoke dispersal conditions. Skies will be mostly cloudy in the north and partly sunny in the south. OUTLOOK (THURSDAY - SATURDAY) Upper flow remains westerly Thursday and Friday with minor embedded impulses moving through the flow. Right now it looks like Friday will be dry, but I can't rule out a couple of showers in the north on Thursday. An approaching trough Saturday will increase the chances for showers. Low level wind flow will remain generally northwesterly. Mixing heights will be mostly in the 3-4000 foot range in the coast range and in the 4-5000 foot range in the Cascades. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 The upper level trough that was over the region on Sunday weakens and moves to the east but no significant ridge develops. In fact another weak upper trough moves out of southern British Columbia into northern Washington. At the surface weak high pressure noses into northwestern Oregon and a thermal trough develops in northern California and extends off the southwestern Oregon Coast. This will give a generally northwesterly transport flow to most areas although southern coastal sections should see a northerly or north-northeast flow. Mixing heights should be high enough for good smoke dispersal conditions. OUTLOOK (TUESDAY - THURSDAY) Upper level winds are generally westerly on Tuesday but a fast-moving upper disturbance rides the flow into the Pacific Northwest on Wednesday. A weak surface front associated with this feature should bring some light rain to northwest Oregon late Wednesday and early Thursday morning. Transport winds will be generally northwest to north on Tuesday, switching to southwest to west ahead of the weak front on Wednesday, then back to north to northwest on Thursday. Mixing heights will remain high and smoke dispersal conditions good. The westerly component to the transport winds will make burning in the north coast range problematical. 2.

In addition, the smoke management office will switch from 7-day-a-week operations to Monday through Friday, 0630 - 1700. If you plan to burn while we're not writing forecasts and instructions, please call us at 503-945-7401 to coordinate. We will resume regular written forecasts in the fall when burning increases again.**** 1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level trough will move through overnight bringing continued cloud cover and a chance of some light showers west of the Cascades. Upper level ridge will start building into the state on Friday with clouds dissipating and giving way to afternoon sunshine. Air mass will generally remain unstable except for some night and early morning stability. Wind flow will be mostly NW to N as surface high pressure builds in. Wind speeds will be mostly light and lead to fair to good smoke dispersion. OUTLOOK (SATURDAY - MONDAY) Upper ridge continues building in over the state early Saturday before shifting eastward by the next trough in the eastern Pacific. Saturday will be the warmest day of the period with inland locations getting into the 80s and 90s. Next trough will probably initiate a late Saturday marine push and bring low clouds into the inland valleys on Sunday. The trough will remain over the state through Monday keeping low clouds over the region during the night and morning hours but breaking up some during the day. Smoke dispersion will be fair on Saturday, and then improve Sunday and Monday. 2.
