DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level ridge will continue to build along the coast today and intensify offshore flow tonight and Wednesday. Offshore flow will clear out the fog in most low lying areas west of the Cascades. Air mass will remain very stable but increasing wind flow will improve smoke dispersion. OUTLOOK (THURSDAY - SATURDAY) Upper level ridge begins to weaken Thursday as dry cold front approaches. Offshore flow will be on the decrease. Upper low behind the front will drop into the state from the north and bring much cooler conditions beginning Friday. Wind flow turns onshore to northerly. As the low drops southward, cold arctic-like air will move in Saturday bringing the coldest conditions of the season. Wind flow turns offshore again. While the air mass remains stable through the period, enough wind flow will provide fair smoke dispersion, improving to good dispersion on Saturday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 ** Cold weather developing for the weekend ** An upper ridge will cover the eastern Pacific on Thursday with upper flow generally northerly over the Pacific Northwest. This is a dry pattern with cool night-time temperatures. In the north offshore flow will be quite brisk but expect only light easterly flow in the south. Mixing heights will be low for poor to marginal smoke dispersal conditions. OUTLOOK (FRIDAY-SUNDAY) On Friday an upper level trough over southwest Canada will drop south-southeast into the region. Moisture will be limited but there is a possibility of some snow flurries with this system. The low will settle in over the area for Saturday and Sunday. Models differ on the exact location and configuration of this low but there seems to be consensus on only limited moisture. Temperatures will be very cold, coldest of the season, and there will be a continued possibility of snow flurries. With the upper low mixing heights will rise for improved smoke dispersal conditions. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 1000 - 1600 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Dry cold front and trough will drop down from the north this afternoon and evening and bring cooling temperatures aloft. Once the front moves through overnight, wind flow will increase from the NE to E and bring chilly surface winds to the region. Air mass will destabilize some as the cooler air moves in. Smoke dispersion will become mostly good by tomorrow afternoon. OUTLOOK (SUNDAY - TUESDAY) Another more arctic-like front will drop southward Saturday night to Sunday morning bringing very cold temperatures and the chance of some light snow or snow flurries Sunday. Air mass will destabilize completely and wind flow will remain offshore. Cold pool of air settles in over the state for the rest of the period as the upper level low slowly moves to the south of the region. Decreasing wind flow and warming aloft while temperatures remain cold near the surface, will stabilize the air mass again. Smoke dispersion will be the best Sunday then worsen Monday and Tuesday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 A cold, dry, week with a fairly stable atmosphere is in store for western Oregon. An arctic air mass has overspread Oregon. A strong high in the northern Gulf of Alaska combined with an upper low over southern Oregon is giving northeast winds aloft over the region. Surface and transport winds will be generally northeasterly and quite strong except in southwest Oregon where winds will be lighter and more northerly. Mixing heights will provide for mostly generally marginal to fair smoke dispersal conditions. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 2100 - 3100 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Cold weather will continue. Upper flow over the Pacific Northwest is essentially northerly. A weak upper trough will drop down on the northerly flow. Satellite pictures show some clouds with this feature but computer models indicate very limited moisture. There could be a scattered snow shower or two but I expect no significant accumulation. Mixing heights will generally range in the low 2000 to low 3000 foot range for marginal to fair smoke dispersal conditions. OUTLOOK (WEDNESDAY-FRIDAY) A dry upper flow continues over the northwest Wednesday, however following the passage of Tuesday's weak upper trough the flow turns a little more north-northwest. The air mass stabilizes for less favorable smoke dispersal conditions. Northwesterly flow aloft continues in the north on Thursday but westerly flow aloft begins to push into northern California and SW Oregon. There will be a chance for some precipitation in the south and it would be snow except at the very lowest elevations. At this point it looks like precipitation amounts will be limited, however. A weak upper disturbance moves over southern Oregon and northern California Friday to improve conditions in the south. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Wednesday will see continued cold, dry, northerly flow aloft. A surface high pressure area over northern Idaho will give continuing offshore flow to the region. Weather will remain dry. Low level winds will be generally east through northeast. Low mixing heights will mean poor smoke dispersal conditions. OUTLOOK (THURSDAY-SATURDAY) Upper flow becomes slightly more northwesterly and the surface high pressure area moves to southeast Wyoming on Thursday. Low level flow remains offshore and low mixing heights will continue poor smoke dispersal conditions. On Friday upper flow continues to back and becomes west to northwest over the area. Low level flow becomes more south-southeasterly. A weak weather system will move into northern California, but it now looks like moisture will stay south of the border. However, mixing heights will improve slightly. On Saturday an upper trough will move into northern California and spread moisture northward. This will provide brief freezing rain in the south which should turn to rain as warmer southerly winds kick in. In the north continued cold outflow from the Columbia Gorge will keep freezing rain going longer and in the Portland area freezing rain may continue all day. On the bright side, mixing heights should jump considerably on Saturday. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height below 1000 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 The coldest air of the current arctic outbreak will slowly shift east. But not before the entire Pacific Northwest experiences another bone-chilling night. Daytime temperatures on Thursday will likely be a few degrees warmer than on Wednesday. Winds will be light and variable across the region with a tendency to northeast through southeast. Mixing heights will remain quite low, especially in the north for poor to marginal smoke dispersal conditions. OUTLOOK (FRIDAY-SUNDAY) Upper flow goes westerly over the area on Friday. There will still be a very cold outflow of residual arctic air through the Columbia River Gorge which will keep northern sections very cold. A weak weather system will spread generally light precipitation into southwest Oregon. Mixing heights will improve in the south for marginal to fair conditions for burning, but in the north conditions will remain poor to marginal. As the precipitation spreads north freezing rain is possible in inland areas of northwest Oregon. By Saturday most areas will experience warming conditions with scattered rain showers, but areas near the Columbia Gorge will see light freezing rain. Scouring winds will push temperatures above freezing all areas by Sunday. Mixing heights will improve considerably and smoke dispersal conditions will be good. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Cold, northerly flow aloft is gradually slipping to the east as a minor trough and front move up from the southwest. The trough and front moving in will end the arctic air mass of the past week and usher in the normal maritime air mass. Expect moisture to slowly move up from the south tomorrow with a chance of snow or freezing rain in the northern interior valleys Friday night. Air mass will remain very stable with cold air remaining trapped under the warmer air moving in aloft. Wind flow will start picking up from the SE to S over the southern part of the region but remain quite variable and somewhat offshore in the north. Look for continued poor smoke dispersion for another day. OUTLOOK (SATURDAY - MONDAY) The trough and front move in early Saturday beginning the warming and destabilization process of the air mass. Expect mostly rain below 5000 ft except in the north valleys where freezing rain could still be a problem through the day. By Sunday the air mass should be mostly scoured with mixing heights rising to 5000 ft in the afternoon. Cooler air will move in aloft bringing the snow level down to 2000 - 3000 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level low off the northern California coast is lifting a warm front into the region this afternoon. Moisture has started over the southern part of the state and will slowly move northward this evening and into early tomorrow. Low level cold air will be slow to retreat with likely a period of light snow and/or freezing rain in the interior valleys. Eventually, the snow level will rise to near 4000 ft Saturday afternoon. Air mass will destabilize first down south then slowly scour to the north. Expect continued stable conditions and poor smoke dispersion through most of Saturday over the northern half of the region. OUTLOOK (SUNDAY - TUESDAY) The upper trough to the south will gradually combine with the cold trough to the north bringing more showers on Sunday. Snow level will lower to 2000 - 3000 ft. Most lowland areas will scour out of the cold air except for maybe the Columbia Gorge. Minor ridge builds in briefly Monday but this will quickly be overrun by the next frontal system coming in from the west. Look for increasing rain and wind Monday afternoon with the snow level lifting to 4000 - 5000 ft. Moist and blustery conditions continue into Tuesday under strong SW flow aloft. Expect generally good mixing and smoke dispersion through the period. Some stabilization will occur Monday under the ridge but it will be brief. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 A west-southwesterly flow aloft will continue on Wednesday. A weak upper trough will support a Pacific weather system moving into the Pacific Northwest. Mixing heights will remain fairly high for generally fair to good smoke dispersal conditions. Transport winds will be brisk and from the south. OUTLOOK (THURSDAY-SATURDAY) More rain moves into the region on Thursday but warmer air aloft will serve to help stabilize the atmosphere and mixing heights will be decreasing on Thursday. Friday and Saturday a surface high pressure area moves into southern British Columbia. This will further stabilize conditions and lead to low mixing heights and poor smoke dispersal. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 An upper level low pressure area will be over southeast Oregon and move southeasterly out of the state during the day. Behind the low upper flow over western Oregon will be north-northwesterly. The air mass will be quite cool with snow levels down to about 1000 feet in the north and 2000 feet in the south during the morning hours. Precipitation will be on the decrease during the day and end Tuesday night. Mixing heights and good transport winds will provide for fair to good smoke dispersal conditions. OUTLOOK (WEDNESDAY-FRIDAY) On Wednesday a strong upper ridge with its axis about 300 miles west of the coastline will settle in. This will give a cool north to north-northwest upper flow pattern to the region. Subsidence with the ridge will lower mixing heights and smoke dispersal conditions will become poor to unfavorable. The ridge slowly moves east Thursday and Friday but remains to the west of the state. This will keep conditions dry and stable through at least Christmas. 2.

ISSUED: Tuesday, December 22, 2009 2:30 PM Jim Little 1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 ** Dry and Stable Period Next Few Days ** ** Unfavorable Smoke Dispersal Conditions ** Pacific Northwest Weather will be dominated by an upper ridge through the end of the week. On Wednesday the axis of this ridge will be about 200 miles west of the coastline and will essentially remain stationary throughout the day. At the surface highest pressures will be over southern British Columbia. This will give light east-northeast winds to most areas. Mixing heights will allow for only poor smoke dispersal conditions. OUTLOOK (THURSDAY-SATURDAY) The upper ridge continues its slow eastward movement. On Thursday it is just off the coast and on Friday the ridge axis finally moves over Oregon and Washington. The ridge pattern starts to slowly break down on Saturday with only a marginal improvement in smoke dispersal conditions. 2.

ISSUED: Wednesday, December 23, 2009 2:30 PM Jim Little 1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 ** Dry and Stable Period Tomorrow and Friday** ** Unfavorable Smoke Dispersal Conditions ** ** Air Stagnation Advisory issued for Rogue Valley ** Pacific Northwest Weather will be dominated by an upper ridge through the end of the week. On Thursday the axis of that ridge will be right along the Oregon/Washington Coast. Subsiding air with the ridge will make for very stable atmospheric conditions. At the surface higher pressure over eastern Washington and northern Idaho will give easterly winds in the northwestern portion of Oregon but winds in the Rogue Valley will be light. The east winds could offer some burn opportunities over the north coast range, otherwise smoke dispersal conditions will remain poor. OUTLOOK (FRIDAY-SUNDAY) The upper ridge continues to move eastward Friday but little change is expected with respect to smoke dispersal conditions. Computer models are inconsistent on how the pattern will break down but there is an increasing chance of precipitation later Saturday and Sunday as weak disturbances move in from the west. This should help to improve smoke dispersal conditions. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 1000 - 1500 ft. Transport wind NE to E at 9 - 15 mph.
