DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 A very cool air mass for this time of year will remain over the region. Temperatures will be about 10 degrees below average. Moisture will be limited but a few showers are likely with most of those showers being snow. Cool air aloft will keep the atmosphere unstable for good smoke dispersal conditions. OUTLOOK (WEDNESDAY-FRIDAY) Temperatures begin to recover a bit but below average readings will continue Wednesday. Widely scattered showers are still likely and smoke dispersal conditions will remain good. Weak upper level ridging on Thursday will ensure dry weather. Cool air aloft and daytime surface heating will push daytime mixing heights to above 5000 feet but this will be offset by quite light transport winds that may limit burning in some areas. Light winds and clearing skies mean nighttime inversions to trap smoke near the ground during the overnight period. By Friday temperatures should be back to near normal. A weak disturbance moving through a generally westerly flow aloft may produce a few mountain showers. Mixing heights remain high for good smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 An upper level disturbance in the west-northwesterly flow aloft develops into a closed low over Washington by morning. This will produce areas of light rain throughout the region. Once again snow is possible as low as 1500 feet ASL. Mixing heights should be above 5000 feet for good smoke dispersal conditions with a generally northwesterly transport wind. OUTLOOK (THURSDAY-SATURDAY) The upper low moves east and weak ridging aloft develops over the area by Thursday. The showers will end. Maximum mixing heights will remain high but very light transport winds might limit burn opportunities. Friday and Saturday will see light westerly flow aloft with dry conditions. Winds will be generally southeasterly Friday. By Saturday transport winds will be picking up from the northwest and maximum mixing height will remain high.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 THURSDAY The cold upper-level trough that has brought numerous rain and snow showers to the region will shift eastward. Showers should taper off in the morning with skies becoming partly cloudy in the afternoon. A very weak ridge, in a cool and drier northwesterly flow aloft, should limit afternoon convection. Daytime heating will allow for good afternoon mixing with much lighter winds. Temperatures will warm but remain below normal. OUTLOOK (FRIDAY-SUNDAY) Westerly flow aloft, on Friday, will turn progressively more southwesterly Saturday and Sunday. An upper-level trough is forecast to move over the region by late Sunday. Skies will be partly to mostly cloudy with temperatures recovering close to normal. The chance of showers, mainly over the mountains, will increase each afternoon. Nighttime inversions may hold residual smoke close to the ground, through the early morning hours, but daytime heating will provide good afternoon smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 FRIDAY Clearing skies and light winds will lead to unseasonably cold early morning surface temperatures and inversions. A weak upper-level disturbance, in a westerly flow aloft, is forecast to move onshore in the afternoon. It will only be strong enough to produce widely scattered mountain showers in the late afternoon. Mixing should be good with a southerly component to the transport winds. OUTLOOK (SATURDAY-MONDAY) The weak upper-level trough will move over the region Saturday morning. That will force the surface thermal trough into northeastern Oregon with transport winds becoming light. The couplet will continue east Saturday afternoon with good mixing and northwesterly transport winds. Skies should mostly be partly cloudy with near normal temperatures and very limited mountain shower activity. Another upper-level trough will turn the flow aloft southwesterly Sunday with an increasing chance of showers, mainly across the southern districts. Afternoon smoke dispersion should be good with more northerly transport winds. A stronger system will likely bring much cooler and showery weather Monday with snow levels dropping to near 5000 feet. 2.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 MONDAY An upper level low moves into SW Oregon/Northern California during the day. This will produce showers throughout the region with heaviest amounts in southern zones. The air mass will be cool and snow is possible above 4500 feet ASL. Mixing heights will be fairly high for fair to good smoke dispersal conditions. OUTLOOK (TUESDAY-THURSDAY) High pressure aloft develops offshore with the upper low tracking across Nevada and Utah on Tuesday. Showers should decrease rapidly during the day. By Wednesday a thermal trough is well established in central California for a generally northerly transport wind. Also by Wednesday the upper ridge moves over the area and will dominate area weather for Wednesday and Thursday with dry weather likely. Sunshine and daytime heating will help keep maximum mixing heights high throughout the outlook period but the clear skies will aid radiational cooling for nighttime inversions and very low mixing conditions during the overnight period. 2. DISPERSION MONDAY Mixing height 1000 - 2000 ft during the morning. Afternoon mixing height rises to 3500 - 4500 ft then lowers to 1700 - 2700 ft during the evening.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 TUESDAY The upper level low that swung into Northern California on Monday moves across Nevada and Utah while an upper level ridge builds off the coast. A chance of mainly mountain showers continues, but the chances will decrease during the day. Maximum mixing heights should remain high enough for good smoke dispersal conditions. OUTLOOK (WEDNESDAY-FRIDAY) The offshore upper ridge moves over western Oregon Wednesday. This will give northerly upper level flow to the region with dry weather. Maximum mixing heights remain above 5000 feet during the afternoon for good smoke dispersal conditions. Fair skies will allow for the formation of nighttime inversions which will hold smoke from any smoldering units close to the ground during the overnight hours. By Thursday the upper ridge becomes indistinct. Winds aloft go light and variable, and lower level transport winds will be quite light as well. The nighttime inversions continue. Not much change is expected from Thursday to Friday. 2. DISPERSION TUESDAY Zone 630 and 632: Mixing height 1600 - 2600 ft during the morning.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 WEDNESDAY An upper level ridge slowly moves eastward across the region. By late afternoon the axis of this ridge extends from eastern British Columbia to southwestern Oregon. Expect dry northerly upper level flow on the east side of that ridge. Warm daytime temperatures should push daytime mixing heights quite high for good smoke dispersal conditions. Clearing skies at night will allow surface based inversions to form and trap any residual smoke near the surface overnight and into early morning hours. OUTLOOK (THURSDAY-FRIDAY) The upper ridge weakens on Thursday with a light, generally westerly, flow aloft throughout the outlook period. Periodic minor impulses ripple across the region in the westerlies aloft but should do little to affect sensible weather. Weather will remain dry. Skies will be generally sunny. Mixing heights fairly high for generally good smoke dispersal conditions.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 SUNDAY The upper-level ridge is forecast to progress east of the state with increasing southwesterly flow aloft over central and eastern Oregon. The surface thermal trough will shift eastward, to near the Idaho border, by late afternoon, with onshore flow penetrating eastward into the western zones. Morning inversions will give way to fair to good afternoon mixing. Although afternoon transport winds may turn westerly, in the western zones, they should remain southerly over the eastern zones. A moistening southwesterly flow aloft will combine with daytime heating to trigger scattered afternoon showers and thunderstorms. Temperatures will remain above normal. OUTLOOK (MONDAY-WEDNESDAY) The flow aloft is forecast to become increasingly moist and unstable Monday, as it turns southerly in response to trough diving into northern California. Showers and thunderstorms are likely with cooler temperatures. Afternoon mixing should be good with mostly southerly transport winds. However, winds will be highly variable near showers and thunderstorms. The showers will move east of the region by Tuesday afternoon with a drier weak westerly flow aloft. The thermal trough will move well east of the state with onshore flow giving transport winds more of a westerly component. The flow aloft, and at transport level, is forecast to turn southwesterly on Wednesday, ahead of an approaching cold front. 2.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 TUESDAY Weather maps show a large upper level low in the Gulf of Alaska with counter-clockwise flow around the low giving southerly winds aloft to the region. Warmer air with this southerly flow will suppress mixing heights somewhat but there will be plenty of moisture for scattered showers. Expect maximum mixing heights generally around 4000 foot range for fair to good smoke dispersal conditions. Transport winds will be generally northwesterly. OUTLOOK (WEDNESDAY-FRIDAY) A vigorous upper level disturbance rotates around the Gulf of Alaska low. This generates a strong surface low that moves northward off the coastline during the day. Rain from this system crosses the Cascades during the afternoon. Thus expect dry weather early then significant (for this time of year) rainfall in the afternoon and evening. By Thursday the Gulf low splits and a portion moves to off Vancouver Island. This will continue to rotate enough moisture into the area for scattered showers through Friday. Maximum mixing heights should be 5000 feet or above through the outlook period. 2. DISPERSION TUESDAY Zone 630 and 632: Mixing height below 500 ft early rising to 1800 - 2800 ft by late morning.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 WEDNESDAY A deep surface low pressure area will track north-northeastward off the Oregon Coast on Wednesday. Southerly flow ahead of this system will push freezing levels to above 10,000 feet and keep temperatures quite warm. Rain from a Pacific cold associated with the northward-tracking low crosses the Cascades and spreads across the region during the evening hours. OUTLOOK (THURSDAY-SATURDAY) An upper level trough swings through early in the day Thursday. Temperatures will be much cooler. Showers will be on the decrease. Mixing heights will be quite high for good smoke dispersal conditions. Clearing skies overnight will mean low level inversions many areas Friday morning. But daytime heating should help mixing heights recover to near 4000 feet by afternoon for fair to good smoke dispersal conditions. A weak upper level trough will bring scattered showers to the region Saturday. 2. DISPERSION WEDNESDAY Zone 630 and 632: Mixing height below 500 ft early rising above 5000 ft by late morning.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 THURSDAY A complex upper low pressure area continues in the Gulf of Alaska. A portion deepens and upper flow backs gradually from westerly to southwesterly by late in the day. Transport winds will be generally southwesterly shifting to northwesterly during the day. With continued cool air aloft (freezing level down to 5000 feet above sea level), mixing heights should be quite high for good smoke dispersal conditions. OUTLOOK (FRIDAY-SUNDAY) The upper level low moves to off the Washington coast on Friday supporting another weak Pacific front. This will move into western Oregon early in the day then spread to north-central and north-east Oregon during the day. On Saturday the upper level low drifts eastward with enough moisture to continue for scattered showers. By Sunday, as the upper low moves east of the area, upper level flow becomes dry northerly and the showers end for a generally dry day. Transport winds will be mostly light and variable.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 FRIDAY A cold upper-level trough will remain over the entire Pacific Northwest. Another cold front will bring increasing showers in the afternoon along with a chance of thunderstorms. Maximum temperatures will be 10-15 degrees below normal with accumulating snow at elevations above 4500 feet. High mixing heights will make for good smoke dispersal conditions. OUTLOOK (SATURDAY-MONDAY) An unseasonably cold upper-level trough will set up camp over Oregon Saturday with numerous showers across central and northeastern Oregon. There is also a chance of thunderstorms. Elevations above about 4000 feet may get fresh snow accumulations. The trough will slowly push east Sunday and Monday with a progressively drier, more stable, and warmer northwesterly flow aloft. Temperatures will remain well below normal, with the snow level only lifting to around 6000 feet by Monday. Showers will taper off, from west to east, by Monday night. Cool air aloft will maintain high afternoon mixing heights, for good daytime smoke dispersal conditions, after early morning inversions. 2.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 SUNDAY An unseasonably cold upper-level trough will remain over the region with mostly cloudy skies, scattered showers, and a chance of afternoon thunderstorms. Maximum temperatures will warm several degrees, relative to Saturday, but remain well below normal. The snow level will range from 4000 feet in the morning to 5-6000 feet in the afternoon. The upper-lever trough will begin pushing east of the region by evening with the flow aloft drying and turning northwesterly. High afternoon mixing heights will make for good daytime smoke dispersal conditions. OUTLOOK (MONDAY-WEDNESDAY) The upper-level trough will push east of the region Monday with a much drier west-northwesterly flow aloft over northeastern Oregon by Monday afternoon. Partial clearing and decreasing winds will allow some morning low-level temperature inversions to form, so residual smoke may be trapped near the ground. High afternoon mixing heights will provide good daytime smoke dispersal conditions with increasing onshore transport winds. Clearing skies Monday evening will quickly drop mixing heights and could trap residual smoke near the surface. After a chilly morning, a strong southwesterly jet stream is forecast to direct another cold front onshore Tuesday with clouds increasing Tuesday afternoon and showers spreading back into northeastern Oregon by Tuesday evening. Another upper-level trough will bring showers to the region Wednesday with snow levels around 6000 feet. High mixing heights and brisk transport winds should make for good smoke dispersal conditions. 2. DISPERSION SUNDAY Mixing height below 2000 ft early rising to 3500 - 4500 ft by late morning.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 WEDNESDAY An upper level low, elongated NW to SE on an axis from about 600 miles west of Astoria to just off the northern California coast is the main weather feature for Wednesday. Moisture will rotate into the Pacific Northwest on the counter-clockwise flow around that low for scattered showers. Cool air aloft and daytime heating will help to destabilize the atmosphere in the afternoon for an increased chance of showers with the possibility of thunderstorms but also providing for high mixing heights and good smoke dispersal conditions. OUTLOOK (THURSDAY-SATURDAY) The upper low moves to a position just off the northern California coast. Weather Thursday should be a near repeat of Wednesday. Cool air aloft should help provide good smoke dispersal conditions. By Friday the upper low moves into Nevada. Counter-clockwise flow around that low means a more northerly wind pattern aloft over the region. This is a drier pattern, but again, shower can't be ruled out. Finally on Saturday the upper low is out of the picture, surface high pressure noses into Oregon from the southwest and dry weather is likely. Friday and Saturday will see a continuation of high daytime mixing heights and good smoke dispersal conditions. 2. DISPERSION WEDNESDAY Mixing height 2500 - 3500 ft during the morning.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 THURSDAY A strong upper-level trough will remain over the region with the center of circulation just off the northern California coastline. That will maintain a moist and unstable southerly flow aloft over Oregon with numerous showers. Cool air aloft should allow for high mixing heights and good smoke dispersal conditions but may also lead to afternoon and evening thunderstorm development. Maximum temperatures will remain well below normal. The snow level will hover around 6000 feet. OUTLOOK (FRIDAY-SUNDAY) The upper-level trough axis is forecast to move over northeastern Oregon Friday morning, before shifting into Idaho Friday evening. That will maintain considerable shower activity with increasing northwesterly winds ushering drier air, from west to east, across the region during the afternoon and evening. Maximum temperatures will remain well below normal with the snow level staying near 6000 feet. Cool air aloft will maintain good daytime smoke dispersal conditions. A transitory and weak upper-level ridge is forecast to bring mostly dry weather to northeastern Oregon Saturday and Sunday. Clearing skies will make for chilly overnight periods with inversions forming. Daytime smoke dispersal conditions will be fair to good with maximum temperatures recovering close to normal by Sunday. 2.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 FRIDAY The offshore upper-level trough, responsible for the cool and damp weather this week, is forecast to finally move over northeastern Oregon by Friday afternoon. That will maintain considerable shower activity across the region with well below normal temperatures and a 5-6000 foot snow level. Increasing northwesterly winds will begin to usher drier air, from west to east, across the region late in the day. Cool air aloft will maintain good daytime smoke dispersal conditions. OUTLOOK (SATURDAY-MONDAY) The trough axis is forecast to shift eastward, to over Idaho, by Saturday morning, with the flow aloft turning northwesterly and beginning to stabilize and dry the air mass. Some showers will likely linger into Saturday afternoon, mainly over the eastern mountains, with temperatures remaining well below normal. Clearing skies will make for a cold Saturday night with low-level temperature inversions trapping residual smoke near the surface. A weak and transitory upper-level ridge will bring partly cloudy to mostly sunny conditions by Sunday afternoon. Maximum temperatures will recover close to normal with fair to good afternoon smoke dispersal conditions. The flow aloft will turn southwesterly Monday with fair to good smoke dispersal conditions but also increasing clouds and a chance of showers. 2.

SMOKE MANAGEMENT FORECASTS WILL RESUME ON MONDAY, MAY 31ST. 1. DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 SATURDAY As a strong upper-level trough finally exits to the east, it will rotate one last disturbance southward across northeastern Oregon. That will keep skies mostly cloudy with a chance of showers, mainly in zones 633-638. Skies will slowly clear, from west to east, during the afternoon, with locally brisk northwesterly winds ushering drier air across the region. Temperatures will remain well below normal. Daytime smoke dispersal conditions will be good, but evening clearing will allow low-level temperature inversions to trap residual smoke near the ground. OUTLOOK (SUNDAY-TUESDAY) A weak and transitory upper-level ridge will bring partly cloudy and dry conditions Sunday. Maximum temperatures will recover close to normal with fair to good afternoon smoke dispersal conditions. A weak weather system, in a westerly flow aloft, will bring increasing clouds by late Sunday. Skies will be with mostly cloudy Monday and Tuesday with cooling temperatures and a chance of showers, mainly over the northern mountains.

DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638 WEDNESDAY An upper level low in the Gulf of Alaska gives west-southwesterly flow aloft over the region. Minor impulses traveling WSW to NNE in the flow keep scattered showers going through the day. Skies will be mostly cloudy and smoke dispersal conditions will be fair to good. OUTLOOK (THURSDAY-SATURDAY) The upper low moves slightly west Wednesday and upper flow over the area becomes slightly more southwest. A more significant impulse drives a Pacific front to the coast early on Wednesday. Rain will spread eastward during the morning and early afternoon. Smoke dispersal conditions will be fair to good. On Thursday the southwest flow aloft continues but the region will be between weather systems. Never the less there will still be enough moisture around for scattered showers. Slightly warmer surface temperatures should push afternoon mixing heights up a bit for generally good smoke dispersal conditions. A more significant spring storm will develop Friday as a surface low off the SW Oregon coast. This will track from SW to NE toward northwest Washington. Look for rain and brisk winds throughout the day. 2. DISPERSION TUESDAY Zone 630 and 632: Mixing height below 1000 ft early rising to 2800 - 3800 ft by late morning.
