DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Flat ridge over the state today is keeping skies mostly fair but an upper level trough will develop to the northwest and move in on Friday. Expect increasing clouds with a chance of some light showers. Because the system is dropping down from the northwest, moisture will be light and limited. Cooler temperatures will follow Friday evening with the snow level dropping down to 4000 - 5000 ft. Air mass will remain mostly unstable, and with light to moderate NW flow, will make for good smoke dispersion. OUTLOOK (SATURDAY - MONDAY) Upper level low continues to drop southward Sunday and forms into a chilly upper level low over the state. This low will gradually slip to the southeast Sunday leaving the region under chilly northerly to offshore flow through Monday. Air mass will remain mostly unstable except for brief late night and early morning stability. Air mass will dry Monday as moisture moves off to the east with the low and a high pressure ridge noses in from the west. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 An upper level ridge axis will remain about 600 miles west of the coastline. Clockwise flow around that ridge leaves the Pacific Northwest in a generally north or northwesterly flow pattern aloft. Mixing heights will be somewhat suppressed for marginal to fair smoke dispersal conditions. OUTLOOK (THURSDAY-SATURDAY) The pattern changes little for Thursday with northwesterly flow aloft over the region for dry weather. By Friday the ridge axis moves a little closer and sharpens although it is still some 500 miles west of the coastline. A pattern change begins on Saturday as the ridge weakens and splits. This will eventually allow a Pacific system to undercut the ridge and bring rain to the region the first part of next week. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 The sharp upper level ridge that brought fair weather to the area Sunday will split with the major portion retreating northward on Monday. This will allow a system now over northern Canada to retrograde to off the British Columbia coast. At the same time a weather system now over the Pacific Ocean will move toward the southern Oregon coast. Rain should hold off until Tuesday. In the north the east or southeast winds will continue while southern zones will see southerly winds becoming southwest to west during the day. OUTLOOK (TUESDAY-SATURDAY) Rain spreads into western Oregon Tuesday with southern sections getting the precipitation first. But by noon the entire western portion of the state will see rain. Flow aloft will be southwesterly, with east-southeast winds in the north and south-southeast winds in the south shifting to southerly and increasing during the day Tuesday. Wednesday will see southwest flow aloft with the rain continuing. Snow will be confined to the high Cascades above about 7000 feet. The rain tapers off in the south, but continues in the north Thursday, slowly lifting northward into Washington late in the day. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 A fairly deep surface low pressure area moves up from the southwest then tracks northward about 250 miles west of the Oregon/Washington coast on Tuesday. This does not look like a big wind producer but winds will be a bit gusty on the coast. Rain spreads across the region during the morning and continues through the afternoon and evening. Amounts will be significant, greatest since last spring most areas, however the heaviest rains will actually move into northern California. Mixing heights will initially be suppressed somewhat in northern zones due to warm air aloft streaming north ahead of the Pacific system. OUTLOOK (WEDNESDAY-FRIDAY) Expect post-frontal showers on Wednesday. Snow levels should be 7000 feet or above. Mixing heights should be quite high for good smoke dispersal conditions. On Thursday a front moves mainly into northwest Oregon and western Washington. Expect rain in the north and showers in the south. Another Pacific front drags across northwest Oregon for rain there Friday. This system sags southward and stalls Friday night bringing rain to most of western Oregon. 2.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 During the day on Wednesday an upper level low consolidates west of southern British Columbia. Post frontal showers continue through the day. Mixing heights should be generally favorable for good smoke dispersal. Transport winds will be generally southwesterly. OUTLOOK (THURSDAY-SATURDAY) The upper low weakens and moves northwest slightly allowing higher pressure to build aloft. The ridge axis will be over eastern Oregon/eastern Washington. This will give mostly dry weather to the region. Mixing heights should still be high enough for fair to good smoke dispersal conditions on Thursday. The ridge axis shifts slightly east on Friday but dry weather will continue. By Saturday the remains of a weak front will move through giving a chance of light rain. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level ridge has built over the region today diminishing the rainfall activity but still allowing plenty of cloud cover. This ridge will slowly slip to the east tonight and Friday allowing a very wet front to move into the northwest corner of the state tomorrow. Models show this front stalling as it moves into northwest Oregon and dumping plenty of rain. Most other parts of the region, including the southwest and the Cascades eastward, will see very little, if any, rain tomorrow. Air mass will remain fairly stable as warm air remains aloft. Areas where low level warming occurs due to less cloud cover will have better mixing. Breezy southerly wind flow will provide good smoke dispersion. OUTLOOK (SATURDAY - MONDAY) Upper level trough and front finally push through the region Saturday and Saturday night after being stalled along the coast from Friday. Rain will decrease later Saturday. Minor ridging builds in Sunday, then will be followed by yet another front and upper low Sunday night and Monday. Air mass will destabilize Saturday as the first front and trough move through. Air mass stabilizes some on Sunday, and then destabilizes again Monday. Smoke dispersion will be mostly good to excellent through the period. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level ridge is stubbornly shifting to the east. Incoming frontal system will mainly stay off the coast today so rainfall over the northwest corner of the state is much reduced from what was expected yesterday. The front will hang mainly off the coast overnight before kicking onshore on Saturday. Rain will increase then in most areas west of the Cascades. Air mass will destabilize as the front moves in with only minor stability tomorrow morning. Increasing southerly wind flow should make smoke dispersion mostly good to excellent. OUTLOOK (SUNDAY - TUESDAY) Weak ridging builds in Sunday following Saturday's frontal passage. However, the ridge won't be strong enough to dissipate all moisture so expect continued mostly cloudy skies and a chance of showers. Next front and upper low take aim for the state Sunday night to Monday morning bringing another round of moisture. It appears right now that this system will take a more southerly track and give the greatest amount of moisture to the southern half of the state. The low will move by to the east Monday afternoon and evening and yield to another minor ridge early Tuesday. Again, this ridge will last a very short time before another front moves in later Tuesday. For the most part the air mass will be unstable and smoke dispersion good under this highly progressive weather pattern. 2.

Minor ridging builds in overnight and into Sunday providing some modest stabilization. Next front and trough, which takes a more southerly track, will approach Sunday evening. Expect mostly cloudy skies on Sunday with some sun breaks, then increasing clouds again later in the day. Wind flow will be fairly light but with decent afternoon mixing, will make for fair to good smoke dispersion. OUTLOOK (MONDAY - WEDNESDAY) Front and upper level low move into the state early Monday providing another shot of moisture with the heavier amounts over the southern part of the state this time. Low moves through Monday afternoon and gives way to a minor ridge that will develop over the state on Tuesday. Again, this ridge will provide just brief and minor stabilization. Another minor front will approach early Wednesday bringing some more light rain to mostly the north half of the state.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 An upper level ridge moves west-to-east over Oregon during the day on Tuesday. Surface pressure gradients will be weak for light winds most areas. Mixing heights will be suppressed for only marginal smoke dispersal conditions. OUTLOOK (WEDNESDAY-FRIDAY) The ridge axis moves east and an upper trough moves into British Columbia and Washington on Wednesday. The trailing cold front will bring rain to northwest Oregon early, with the rain spreading to southwest Oregon by afternoon. Amounts will be light, generally less than a half an inch and even lighter in southern zones. Transport winds will pick up and be generally from the southwest except for light flow in the vicinity of the Rogue Valley. Thursday and Friday an upper ridge builds over the area for dry weather but also light winds and low mixing heights. Thus smoke dispersal conditions will be poor both days. Recommend not planning units near smoke sensitive areas Thursday and Friday. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 1000 - 1900 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Tuesday's upper ridge axis shifts east and an upper trough moves mainly into British Columbia and Washington on Wednesday. The trailing cold front is rather weak since most of its support well to the north. Rain will reach the north coast early in the morning and spread slowly south and east. However, rainfall will be light, around .25 in the north coast range, .10 in the Willamette Valley and just a few sprinkles elsewhere. The weak front will do little to help push mixing heights up and smoke dispersal conditions will remain poor to marginal. OUTLOOK (WEDNESDAY-FRIDAY) Another upper ridge builds over the area for dry weather and light winds Wednesday - ventilation conditions will be poor in the north marginal to fair in the south. The ridge axis aloft shifts slightly east and another very weak front spreads some light rain to northwest Oregon by Friday evening. This will be followed by another upper ridge Saturday. There is some evidence of a pattern change beginning Sunday or early next week that should alleviate the stagnant conditions in the valleys. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 In the upper atmosphere a ridge builds over the region. At the surface an area of high pressure pushes in from the southwest and blankets the entire Pacific Northwest by afternoon. This will suppress mixing heights and give light transport winds to the area. Mixing heights will be very poor to poor in the north coast range and marginal elsewhere. OUTLOOK (FRIDAY-SUNDAY) An upper trough approaches the Pacific Northwest on Friday. A warm front brushes extreme northwest Oregon during the afternoon but the following cold front holds off until evening. Rain continues Saturday with relatively low mixing heights especially in the northwest portion of the region. A surface high builds in again Sunday further suppressing mixing heights for poor smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level ridge has built over the state today but is getting flattened somewhat by an approaching storm system. The warm front will ride over the top of the ridge this afternoon and evening providing some light rain to the northern part of the state today. The cold front will then ride through on Friday with increasing moisture during the morning, continuing into the afternoon. Air mass is quite stable under the ridge and will remain so until the cold front can bring cooler air aloft tomorrow afternoon. Smoke dispersion will be poor overnight then improves through the day as SW'erly flow increases Friday morning. OUTLOOK (SATURDAY - MONDAY) Upper level ridge will rebuild over the state Saturday following Friday's front. Air mass stabilizes again. Ridge will continue over the region into Sunday before another front moves in during the afternoon. Expect another round of moisture Sunday afternoon and evening turning to showers on Monday. Snow level appears it will lower below 5000 ft on Monday. Cooler air aloft will destabilize the air mass again on Monday. Expect poor to fair smoke dispersion Saturday and most of Sunday then improving dispersion Sunday afternoon through Monday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Cold front is moving through the region today bringing decent rains to mainly the north half of the state. Upper level ridge will quickly rebuild tomorrow, stabilizing the air mass and reducing wind flow. Expect a fair and dry day on Saturday with patchy morning fog in the valleys. Smoke dispersion will decrease considerably from today under the building ridge. OUTLOOK (SUNDAY - TUESDAY) Upper ridge will remain over the state Sunday but a warm front will overrun it, bringing another round of moisture beginning Sunday afternoon. Air mass will remain stable but smoke dispersion will improve as SW'erly flow increases. The trailing cold front will move through on Monday bringing plenty of moisture and cooler, unstable conditions. Upper trough moves through later Monday with chilly northerly flow following on Tuesday. Showers decrease. By later Monday the snow level will lower to near 3500 ft in the north and lower to near 2500 ft by early Tuesday. Expect plenty of snow in the mountains from this system.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level ridge will continue building over the state today and tonight, further stabilizing the air mass. Next frontal system will override the ridge Sunday as a warm front spreads clouds over the area during the day with light rain beginning during the mid to later afternoon. Moisture will continue spreading eastward over the Cascades Sunday night. Increasing wind flow from the southwest will slowly improve smoke dispersion. OUTLOOK (MONDAY - WEDNESDAY) Ridge slides to the east early Monday giving way to the cold front and upper level trough. Expect a fairly generous amount of moisture over the region. Cooler air will move in aloft to destabilize the air mass and lower snow levels. Upper trough moves by to the east Tuesday but with a strong northwesterly jet stream over the region, cool showers will continue with the snow level lowering to near 3000 ft. Air mass will be quite unstable. The next upper level ridge starts building in Wednesday but with chilly air remaining over the region, the air mass will remain mostly unstable. However, decreasing wind will worsen smoke dispersion from the dispersion of Monday and Tuesday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 A Pacific weather front moves through the region Sunday night followed by another surge of moisture Monday morning. Expect wet weather all of western Oregon during the day. Amounts of one inch are possible. Cooler air aloft filters in behind these weather systems and snow levels lower to below the Cascade passes. Snow amounts of 10 inches are possible above about 4000 feet by Tuesday morning. Mixing heights should provide for fair smoke dispersal conditions most areas. OUTLOOK (TUESDAY-THURSDAY) An upper level ridge builds in the eastern Pacific. Post frontal showers continue on Tuesday. By Wednesday just widely scattered showers are likely. Mixing heights remain high enough for fair to good smoke dispersal conditions. The ridge in the eastern Pacific pushes the next surface low well to the north into southeast Alaska, but a warm front extends southward from that low and clips Washington and Oregon for some light rain in much of western Oregon on Thursday. Warmer air aloft will suppress mixing heights somewhat, but smoke dispersal conditions still look generally marginal to fair for the end of the week. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 The wet Pacific cold front that brought considerable rain to western Oregon Monday will be well to the east and dissipating. The cool upper trough supporting that system will move to the northern Rockies leaving a cool northerly flow aloft over Oregon. This will keep the atmosphere destabilized with mixing heights above 4000 feet most areas. Winds will remain brisk for favorable smoke dispersal conditions most areas. Expect scattered showers, occasionally heavy, during the day, gradually dissipating by late afternoon. OUTLOOK (WEDNESDAY-FRIDAY) An upper level ridge builds in the eastern Pacific and moves over the region on Wednesday. Weather will be dry, however the ridge will progress to the east and allow another Pacific warm front to approach Wednesday evening. Expect rain Wednesday night and then more rain Thursday as a cold front sags across the Pacific Northwest. Friday will see showers with another Pacific cold front due in on Saturday. Mixing heights should remain high enough for good smoke dispersal conditions through the outlook period. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 The Pacific Northwest will be on the eastern edge of a broad upper level ridge in the eastern Pacific on Wednesday. This will shunt a strong surface low into southeast Alaska but a warm front will extend southward to off the Washington and Oregon Coast. Rain from this front should hold off until overnight and into Thursday morning. Warmer air aloft will suppress mixing heights in the north for marginal to fair smoke dispersal conditions. Winds will be generally light and variable. OUTLOOK (THURSDAY-SATURDAY) The upper ridge gets suppressed southward Thursday as a strong upper jet develops in the eastern Pacific and into central British Columbia. The warm front spreads rain into northwest Oregon but only light amounts reach into southwest Oregon. Mixing heights improve in the north Coast Range, but decrease in the Cascades and the south coast range. By Friday temporary ridging aloft reestablishes itself. A weak warm front brings more precipitation, mainly to northern sections. Warm air aloft ahead of this system also further suppresses mixing heights many areas for poor smoke dispersal conditions in the rogue Valley and marginal to fair conditions elsewhere. A cold front on Saturday will push mixing heights higher for better smoke dispersal conditions early in the weekend. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level ridge continues to build over the state but is being overrun by clouds from a warm front off the coast. This front will slowly move into the state overnight and Thursday bringing light moisture that will be mainly confined to the north half of the state. Air mass will remain stable as warming air aloft continues to enhance the lower level temperature inversion. Increasing wind flow from the south should provide fair smoke dispersion. OUTLOOK (FRIDAY - SUNDAY) Upper ridge with warm front clouds and light moisture continues through Friday before the ridge flattens and gives way to a cold front Friday evening to Saturday morning. Moisture amounts with the cold front will also be fairly light. Air mass will destabilize Saturday for a brief period before stabilizing again Saturday night and Sunday as the upper ridge rebuilds again. Wind flow will increase ahead of the front on Friday providing decent smoke dispersion. Winds then decrease on Saturday and become quite light on Sunday, making that day the worst for smoke dispersion. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level ridge will remain over the region tonight and into early Friday before flattening and giving way to a cold front late Friday and early Saturday. Currently the warm front is arcing over the ridge and spreading clouds and light moisture over the state today. This will diminish tomorrow as the warm frontal zone moves off to the east. Air mass mixes out with the warm air aloft mixing down to the surface and improving mixing conditions, especially north. Brisk wind flow will also assist in improving smoke dispersion. OUTLOOK (SATURDAY - MONDAY) Cold front moves into the state early Saturday morning, gradually breaking apart as it moves through. Moisture amounts will be generally light. Upper ridge will then rebuild Sunday, stabilizing the air mass again. Ridge moves off to the east Monday as another weak front approaches. Air mass will remain stable and smoke dispersion mostly poor Sunday and Monday after a good day on Saturday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Cold front moved by to the east this morning and will give way to a fairly flat upper level ridge tomorrow. Air mass will slowly stabilize overnight as skies clear. Some patchy fog is likely in the inland valleys Sunday morning. Surface high pressure will build to the north and turn wind flow offshore. This should make for some decent burn opportunities in the Coast Range. Smoke dispersion, however, will be mostly poor to fair. OUTLOOK (MONDAY - WEDNESDAY) Upper ridge will remain in place Monday and Tuesday keeping the air mass stable and smoke dispersion poor. Expect some morning fog in the valleys with clearing skies during the afternoon. A minor front will bring increasing clouds and a chance of rain to mainly the northern part of the region Wednesday afternoon. Air mass will remain stable but increasing SW'erly flow will improve smoke dispersion then. 2.
