DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 A Pacific cold front enters northwestern Oregon overnight Wednesday night and sweeps across the state during the day on Thursday. Rainfall will be heaviest in the northern zones but rain will reach all the way to the California border. Behind the front a fairly strong WSW to NNE pressure gradient will give blustery onshore flow. Transport winds should be generally westerly, backing to west-northwesterly later in the day. Mixing heights will be high for excellent smoke dispersal conditions. OUTLOOK (FRIDAY - SUNDAY) Showers will begin to taper off Friday and onshore pressure gradients will relax for less wind. Transport winds will be generally northwesterly across northwestern Oregon with more of a tendency for northerly winds in the southwest portion of the state. The air mass will stabilize Saturday but mixing heights should remain high for fair to good smoke dispersal conditions. Saturday and Sunday look dry as a Pacific system splits and most rain moves into California before rotating northward Monday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 The upper level ridge that moved over the region over the weekend will flatten and move to the east while an upper level low pressure area will move into central California on Tuesday. At the surface a thermal trough will shift inland and low level flow will go onshore mid-day. Computer models differ on exact direction but some areas will see a northwesterly flow but most areas will se a southwesterly transport flow as the winds shift. The California low will rotate some high clouds into the region but any rainfall will hold off until tomorrow evening in the south and until Wednesday in the north. Mixing heights will remain favorable for good smoke dispersal, but the main message is the low level wind shift coming Tuesday. OUTLOOK (WEDNESDAY - FRIDAY) The California upper low will shift into Nevada and Utah on Wednesday and low level flow will remain onshore with transport winds backing from southwesterly to more southerly throughout the day. Another upper level low cuts off, this time off the northern California coast, by Thursday evening with low level flow eventually shifting to northwesterly. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Complex weather pattern is over the region today with an upper level low to the south and a ridge to the north. The low will spin up some light moisture into southwest Oregon this afternoon and overnight. The upper level ridge to the north will gradually slip to the east and give way to an incoming trough later Wednesday. For the most part, expect increasing clouds and cooler conditions as offshore flow turns to onshore later this afternoon and evening. Onshore, SW'erly flow will get firmly established over the region on Wednesday. Cooling aloft will destabilize the air mass and make for better smoke dispersion conditions. OUTLOOK (THURSDAY - SATURDAY) Upper level trough in the eastern Pacific will gradually move in and bring a cold front to the region on Thursday. Snow level will lower to 3500 - 4500 ft. Upper level trough moves through Friday bringing scattered showers and continued cool, unstable conditions. A minor ridge moves in on Saturday bringing mostly dry conditions but remaining cool and unstable. Smoke dispersion will remain good to excellent through the period. 2.

This will continue until burning declines considerably toward the beginning of summer. Please call 503-945-7401 if you have questions or waivers to the instructions.**** 1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Minor upper level ridge builds into the state early Saturday but will provide little in the way of warming and drying. In fact, a minor disturbance will ride through the ridge and provide clouds and some sprinkles to the northwest corner of the state. Residual cool air aloft will maintain good mixing levels. Onshore flow will continue through the day, and along with good mixing heights, will make for good to excellent smoke dispersion. OUTLOOK (SUNDAY - TUESDAY) Upper ridge moves by to the east Sunday giving way to a decent frontal system and upper level trough. Overrunning moisture will move onto the coast during the morning and spread inland through the morning through the afternoon. Expect plenty of moisture, especially over the northwest corner of the state. Front will move through during the later afternoon and evening with considerably cooler air moving in behind. Snow level will lower from near 6000 ft early Sunday to 4000 ft late Sunday and down to near 2000 ft Monday. Upper trough will move through Monday providing cool showers. Trough moves by to the east Tuesday leaving the region under chilly but drier NW flow. Smoke dispersion will be mostly good to excellent through the period. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 The cold front that passes through the region Sunday evening ushers in a cool upper level trough that will bring numerous showers to the area Monday. Snow level will likely be near three thousand feet in the north and three to four thousand feet in the south. Greatest precipitation totals will be in the north. Transport winds will be generally westerly except northwesterly in extreme southwest Oregon. With the cool air aloft mixing heights will give good to excellent smoke dispersal conditions. OUTLOOK (TUESDAY - THURSDAY) The upper level trough axis will move east of the Cascades on Tuesday but cold impulses moving down from the north will keep showers going throughout the day. Transport winds will be generally northwesterly. By Wednesday the showers will be mostly over except over the Cascades. A dryer northerly flow aloft takes over in advance of an upper level ridge offshore. On Thursday that ridge will move over the region for dry weather but much suppressed mixing heights and only poor to fair smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 The cool upper level low that has been over the region for the past couple of days will finally drop south into Nevada overnight Tuesday night leaving the Pacific Northwest in a northerly flow aloft early in the day. A few showers are still possible early, mainly over the Cascades. A weak upper ridge will build during the day ending any showers. Transport winds should be generally northwest across western Oregon, backing to westerly in northern zones in the afternoon. Mixing heights should allow fair to good smoke dispersal conditions. OUTLOOK (THURSDAY - SATURDAY) On Thursday flat ridging should keep the area dry. Expect southerly winds most of western Oregon, but more of a westerly or northwesterly wind in the Rogue Valley. Computer models are not as strong on the ridge as they were yesterday and thus it now looks like mixing heights will remain higher than previously thought. Expect fair to good smoke dispersal Thursday. Models are now showing a weak Pacific cold front for Thursday night and Friday with dry weather returning for the weekend. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Thursday will see a weak upper ridge moving slowly eastward over the region. A weak Pacific cold front will approach the coast during the day, but rainfall should hold off until Thursday evening. Rain should eventually spread to the California border Thursday night with rainfall totals of near a quarter of an inch in the north Coast Range to less than a tenth of an inch over the southwestern portion of Oregon. Transport winds will be generally south-southeast to south-southwest, except westerly in southwestern Oregon. Mixing heights should be high enough for fair to good smoke dispersal conditions. OUTLOOK (FRIDAY - SUNDAY) The front weakens Friday without making much of an eastward push and an upper trough moves through late in the day. Expect cloudy skies and a few areas of light rain Friday. Winds will begin southerly and then switch to a more west or northwest direction later in the day. Smoke dispersal conditions will be fair to good. A surface high develops over Washington with a thermal low in northern California on Saturday. The high shifts to the northern Rockies on Sunday while the thermal low shifts to the Cascades. Saturday expect a generally northeasterly flow except easterly in the Rogue Valley with winds becoming northwest late in the day. Mixing heights will lower somewhat over the weekend for deteriorating smoke dispersal conditions. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 1900 - 2900 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level ridge is building over the state today with just some variable high clouds running through the ridge. Ridge will continue building in tonight and tomorrow with clouds dissipating. Expect a sunny and warm day tomorrow. Air mass will stabilize with only interior locations in southwest Oregon and east of the Cascades breaking the temperature inversion enough to have a brief period of good mixing during maximum heating. Wind flow will be light, favoring offshore flow during the morning and onshore NW to N flow during the afternoon. Smoke dispersion will be mostly poor. OUTLOOK (MONDAY - WEDNESDAY) Upper level ridge continues to build over the state through Monday before weakening and shifting eastward on Tuesday. Expect Monday to be the warmest day of the period with inland lowland locations reaching the upper 70s to upper 80s. As the ridge shifts eastward on Tuesday, it will open the door to a marine push Tuesday afternoon. Upper level trough and front move in Wednesday increasing shower activity and bringing considerably cooler air. Air mass destabilizes Wednesday. Look for poor to fair smoke dispersion Monday, improving dispersion Tuesday afternoon, then mostly good dispersion Wednesday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 A broad upper level ridge will continue over the Pacific northwest Monday. A weak thermal trough will settle in east of the cascades. Higher pressure offshore will give generally north-northwest winds except in the Rogue Valley where morning winds will be northeast before switching to north-northwesterly. Mixing heights along the coast and in the coast range will be suppressed with highest mixing heights and best smoke dispersal conditions in the southern Cascades. OUTLOOK (TUESDAY - THURSDAY) The upper ridge flattens in response to an upper level low moving across the northern Gulf of Alaska on Tuesday. Pressure gradients will be quite flat. Transport winds will be generally north to north-northwest. By Wednesday an upper level trough will be approaching, temperatures aloft will be cooling and the atmosphere will be destabilizing for better smoke dispersal condition. The trough will still be to the northwest on Thursday with more cooling aloft for better smoke dispersal conditions but any rain should hold off until late Thursday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 The ridge of high pressure in the upper atmosphere that has brought the sunshine and warm weather to the Pacific Northwest will remain on Tuesday; however it will start to weaken as an upper level low pressure area moves across the northern Gulf of Alaska. The warm temperatures at the surface will continue and may produce enough instability to touch off some isolated afternoon or evening thunderstorms over the southern Cascades Tuesday evening. Mixing heights should be favorable for good smoke dispersion, reaching to 5000 feet during the afternoons after morning surface inversions break Transport winds will be generally north to north-northwest except light and variable becoming northwest in the Rogue Valley. OUTLOOK (WEDNESDAY - FRIDAY) The tail end of the Gulf of Alaska low digs south to off the British Columbia coast on Wednesday, but weather will remain dry. Isolated afternoon thunderstorms are still possible over mountainous areas. Transport winds will be similar to Tuesdays. On Thursday the upper trough sweeps into the Pacific Northwest. Moisture will be very limited but isolated showers are likely throughout the region. By Friday the trough axis will be east of the Cascades and surface high pressure re-intensifies off the coast for a continuing northerly component to transport winds. Afternoon maximum mixing heights should be favorable for good smoke dispersal throughout the outlook period. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 An upper level trough extending southwestward from a low in northern Alberta begins to move into the northwest Washington during the day on Wednesday. Temperatures aloft will be cooling dramatically, destabilizing the atmosphere and providing good smoke dispersal conditions. There will be limited moisture with this trough but some isolated showers are possible. Expect transport winds to be generally northwesterly most areas. OUTLOOK (THURSDAY - SATURDAY): The upper level trough sweeps through the region on Thursday further destabilizing the atmosphere over the Pacific Northwest. Again, limited moisture, but showers are possible especially over mountainous areas. By Friday the trough axis will be east of the Cascades and western Oregon will be in a generally dry, northerly flow on the back side of the trough. However there will still be a slight chance of a shower over the Cascades. Saturday will see the upper trough well to the east, over the northern Rockies with surface high pressure centered several hundred miles west of Oregon. A minor upper disturbance dropping south-southeast will cause some instability for a continued slight chance of a shower but also continued good smoke dispersal conditions. Transport winds through the outlook period should stay in the west through north quadrant. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 3900 - 4900 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Dry cold front will move down from British Columbia today to usher in considerably cooler air and variable cloud cover. Front doesn't appear to have enough juice to bring any widespread moisture, just isolated sprinkles. Air mass will destabilize throughout the day as the cooler air moves in aloft. Upper level trough will move through tomorrow and keep the air mass mostly unstable. Expect considerable marine low clouds over the west side of the state as cool, onshore flow remains. Smoke dispersion improves throughout the day today and will be good to excellent Thursday. OUTLOOK (FRIDAY - SUNDAY) Following the passage of the upper level trough later Thursday, the region will remain under cool, northerly flow through the period. Another minor disturbance may move through the northerly flow on Sunday bringing some light, scattered showers. Expect mixing and smoke dispersion to be good through the period. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Some showers are falling over northwest Oregon. These are associated with the upper air trough crossing the area this afternoon. The showers are expected to end overnight and clouds decrease. This leaves the area under northerly flow aloft as a ridge strengthens to the west. Under the northerly flow and clearing skies temperatures overnight will be cool with frost likely in sheltered areas. Air mass begins to stabilize a little but the axis of the ridge remains too far west to seriously worsen mixing. Low level flow remains generally northwesterly. OUTLOOK (SATURDAY - MONDAY) Ridge remains nearly stationary off the coast with cool northerly flow over the Pacific Northwest. A couple of minor disturbances slide south out of Canada bringing some cloudy periods over the weekend and a slight chance of some rain or showers Saturday night or early Sunday. Mixing remains fairly good as the ridge stays too far to the west to cause the air mass to stabilize. Nighttime cooling will result in poor mixing from after sunset through early morning. Low-level wind flow mostly northwest to north through Sunday. Likely to see a slight tendency to offshore flow Monday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Models show an upper short wave moving down from the north on Monday to keep the atmosphere a bit unstable. Moisture is limited but there is a good chance for some mainly afternoon showers. Mixing heights should be quite high for good to excellent smoke dispersal conditions. Transport winds will be generally west through northwest. OUTLOOK (TUESDAY - THURSDAY): A second upper level short wave drops south on Tuesday eventually carving out an upper level low pressure area centered over Northwest Oregon. This will continue cool temperatures and snow levels could drop to around 3000 feet. The atmosphere will be unstable for good smoke dispersal conditions. In the north winds will be southerly early, turning to westerly later. In the south expect winds from the southwest through south. The upper low meanders ultimately splitting with a portion moving east and a portion retrograding to the west. Showers will end later Wednesday as the air mass stabilizes somewhat, but smoke dispersal conditions should remain good. In the north transport winds will be easterly early then switch to the north. Southern zones will see northerly winds. By Thursday weak ridging aloft will again cover the Pacific Northwest. Mixing heights will remain favorable for good smoke dispersal and winds will be mostly from the east through northeast. Main message through the outlook period: Good dispersion but changing transport wind directions requiring close monitoring and coordination for locations near SSRA's. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 An upper level disturbance dropping southward from British Columbia on Monday will develop into an upper level low over the Pacific Northwest on Tuesday. This will produce periods of rain throughout the day for most of the area. The rain will taper off later in the day, but showers are likely through Wednesday. With the cooler air aloft the atmosphere will be rather unstable and mixing heights should be favorable for good smoke dispersal. Expect transport winds to be generally from the southwest or south-southwest. OUTLOOK (WEDNESDAY - FRIDAY): The upper low drifts slowly eastward across the state on Wednesday. Snow levels in the Cascades will be as low as about 3500 feet Wednesday morning. Showers will continue throughout the day. Mixing heights will remain high, but winds will vary through the day. In the north expect easterly winds early, becoming northwest. In the south winds will start out south-southwest and shift to westerly. By Thursday the upper low will pass to the east allowing weak ridging to build over the area. Weather should be dry but winds will again be quite variable; Northwest through west in the north, and northeast through north in the south. On Friday a Pacific weather system moves toward the state from the southwest. Rain will spread northward during the afternoon and a wet weekend is in store. Once again Friday winds will vary with location: In the north generally easterly in the morning then becoming southwesterly, in the south southeasterly becoming northwest.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 The upper low that brought clouds, rain and cool temperatures to the Pacific Northwest will track west to east across the state on Wednesday. This will keep showers going thought the area. The cool air aloft with this system will keep mixing heights high and smoke dispersal conditions should be good to excellent. Transport winds, however, will be highly variable in direction. OUTLOOK (THURSDAY - SATURDAY): On Thursday the upper low slowly pulls out to the east allowing weak ridging to build. Mixing heights should remain high for good to excellent smoke dispersal conditions. Winds will go offshore, generally east through northeast across western Oregon. By Friday a Pacific weather system will approach from the southwest. Models differ on the initial strength of this system but for now it looks like rain reaching southwest Oregon early in the morning with precipitation spreading northward to extreme northwest Oregon by Friday evening. A Pacific cold front moves onshore on Saturday and the weekend looks quite wet.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 The upper low that brought wet, cool weather to the Pacific Northwest has been slow to move out but by Thursday afternoon should be just a memory. There could be a shower or two early lingering over the Cascades, but by afternoon skies should be partly cloudy to mostly sunny for the area. Transport winds in the northern zones will be east-northeast to north while southern sections will see flow from the northeast becoming northwest during the afternoon. Mixing heights should remain high for favorable smoke dispersal conditions. OUTLOOK (FRIDAY-SUNDAY): Overnight Thursday a Pacific weather system approaches Oregon from the southwest. Expect rain by early morning in the southwestern part of the state, spreading north and east during the day. Rainfall amounts will be fairly heavy for this time of year. Winds will vary from east through north in the north and from south to southeast in the south. Mixing heights will remain fairly high in spite of warm overrunning stabilizing the atmosphere somewhat. Another Pacific cold front approaches during the day on Saturday, moving through later in the day to keep rain going most areas. Moist west-southwest flow over the region continues Sunday for wet weather. Mixing heights remain favorable for good smoke dispersal throughout the outlook period. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level trough has exited eastward and is giving way to a temporary ridge tonight and Friday. However, the next upper low and front will move up from the southwest later Friday bringing an increased chance of moisture Friday night. Air mass will stabilize under the ridge with afternoon heating providing fair to good mixing. Wind flow will be offshore and favor burning in the Coast Range. OUTLOOK (SATURDAY - MONDAY) Upper level low moves in Saturday and weakens but will still produce some light rain or showers over the region during much of the day. Sunday will see a lull in the showers, and then another trough and front move in on Monday. This promises to be a stronger system, bringing fairly breezy conditions as well. Air mass will be mostly unstable during the afternoon and somewhat stable during the morning. Expect decent smoke dispersion. 2.
