DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SUNDAY An offshore upper-level ridge will build closer to the coastline with the strong northwesterly flow aloft temporarily weakening. A warm front will increase the clouds across the region during the day with a little rain possible in the north. Smoke dispersion should remain fair to good with onshore flow. Snow levels will rise above 6000 feet. Surface temperatures should recover close to normal. OUTLOOK (MONDAY-WEDNESDAY) A strong cold front is forecast to bring more rain and mountain snow Monday, with snow levels dropping to 3000 feet north and 4000 feet south Monday afternoon. Tuesday looks very cool and unstable with numerous showers and a good chance of afternoon thunderstorms. Shower activity will decrease Wednesday, as the air mass slowly begins to warm. Daytime smoke dispersal should be good. Cold nighttime temperatures could make for low early morning mixing heights, especially on Wednesday. Temperatures will be unseasonably cool with strong onshore flow. The snow level could drop to below 2000 feet on Tuesday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 MONDAY The flat upper ridge that was over the region Sunday gets suppressed as a cold upper trough digs into British Columbia and extends southward into Oregon. The associated front brings windy and cold weather into the area during the day. Rain will start overnight Sunday night in the north and spread southward. Snow levels drop dramatically as the front moves through falling to 2500 feet in the north by late afternoon and to the same elevation by Tuesday morning in the south. Transport winds will be mostly northwesterly to west in the north and southwesterly switching to northwesterly in the south. Mixing heights will be highest in the north with good smoke dispersal conditions, while southern zones will see mixing heights mostly in the 3000 to 4000 foot range for fair smoke dispersal conditions. OUTLOOK (TUESDAY-THURSDAY) The cold upper trough lies east to west over the region on Tuesday with an upper low closing off in southern Washington by evening. Precipitation will be limited but morning snow levels will be just 1500 feet. Widely scattered showers continue Wednesday but the air mass slowly warms and temperatures recover slightly. By Thursday minor ridging cuts off the showers and temperatures bump up a few more degrees but will still be below seasonal averages. Mixing heights throughout the outlook period will be quite high for good smoke dispersal conditions. By Thursday transport wind speeds will drop off and that, along with directional variability, could limit burning opportunities in some areas. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 TUESDAY A very cool air mass for this time of year will remain over the region. Temperatures will be about 10 degrees below average and the freezing level will be down to below 2000 feet ASL in most areas. Models indicate most showers will be confined to northern zones although moisture will be limited. 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 THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY 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. Precipitation amounts will be less than a quarter of an inch in the north and less than a tenth of an inch in the south. 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 north or northeasterly Friday except in the Rogue basin where winds will remain light and variable. By Saturday transport winds will be picking up from the northwest and maximum mixing height will remain high. Clearing skies and nighttime inversions will hold any residual smoke close to the ground during the overnight period. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 THURSDAY The cold upper-level trough that has brought numerous showers and unseasonably low snow levels to the region will shift eastward. Clearing skies and decreasing winds will allow low-level inversions to form early in the morning. However, daytime heating should allow for fair to good afternoon mixing. A very weak ridge, in a cool and drier northwesterly flow aloft, should limit afternoon convection. There will be a chance of mountain showers, but generally look for partly to mostly sunny skies with temperatures recovering to within a few degrees of 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 Sunday afternoon with the flow aloft turning northwesterly Sunday night. Skies will be partly to mostly cloudy with near-normal temperatures. The chance of showers will increase each day. Nighttime inversions may hold residual smoke close to the ground, through the early morning hours, but daytime heating will provide fair to good afternoon smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 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 afternoon. However, it will force the weak thermal trough east of the Cascades. North-northeasterly transport winds will turn onshore late in the day, especially south. OUTLOOK (SATURDAY-MONDAY) A very flat and weak ridge will turn the flow aloft slightly northwesterly Saturday, with continued onshore flow at the transport level. Morning marine clouds should give way to partly sunny skies with near normal temperatures. Afternoon mixing should be fair to good. 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 fair to good with increasing onshore transport winds. A stronger system will likely bring cool and showery weather, to all districts, Monday with snow levels dropping below 4000 feet. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SUNDAY A split-flow jet stream pattern will send another upper-level trough across mainly the southern two-thirds of Oregon. Scattered showers are likely in the southern zones with a chance of mainly mountain showers in the northern zones. Mixing should be fair to good from the late morning through the afternoon with generally westerly transport winds. OUTLOOK (MONDAY-WEDNESDAY) A cold upper-level trough will bring showery and cooler conditions Monday. Snow levels will drop below 4000 feet. Showers will be more numerous over southwestern Oregon with higher elevations likely picking up a few inches of snow. Transport winds should take on more of a southerly component, Monday morning, possibly shifting to northwesterly late in the day. The flow aloft is forecast to become northerly Tuesday, as an upper-level ridge builds just offshore. That should rapidly taper off the shower activity with the onshore flow beginning to turn more northerly. Wednesday looks dry with mostly northerly transport winds and fair to good mixing heights. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 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 2500 feet in the north and 3500 feet in the south. Subsidence on the northwest side of the low will suppress afternoon mixing heights in the north. 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. A surface high noses into Oregon late in the day. By Wednesday a thermal trough is well established in central California for a generally northerly transport wind. Mixing heights will be down a bit Tuesday and Wednesday most areas but smoke dispersal conditions should remain at least fair most areas. The remains of a weak Pacific front move through the area Friday which will turn flow more onshore and improve mixing heights. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 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. Showers are still possible, especially in the morning, and southwestern Oregon could see snow in those showers to about 3500 feet. The proximity of the ridge will suppress mixing heights somewhat but smoke dispersal conditions should remain fair. OUTLOOK (WEDNESDAY-FRIDAY) The offshore upper ridge moves over western Oregon Wednesday. This will continue to suppress mixing heights over the region although they should be high enough for fair smoke dispersal conditions most areas. A weak upper disturbance should improve mixing heights on Thursday and another slightly stronger one will further improve smoke dispersal conditions on Friday. Neither of these systems is likely to produce any precipitation, however. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 3000 - 4000 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 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. Upper level flow will be light northwesterly with dry weather and afternoon sunshine most areas. Temperatures will warm both at the surface and aloft. The warmer temperatures aloft will help suppress maximum mixing heights. 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. 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. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SUNDAY The upper-level ridge is forecast to progress east of the state with increasing southwesterly flow and slow cooling aloft over western and central Oregon. The surface thermal trough will shift eastward, to near the Idaho border, by late afternoon, with onshore flow penetrating east of the Cascades. Morning inversions will give way to fair to good afternoon mixing. Southwesterly flow aloft will combine with daytime heating to destabilize the air mass enough for scattered afternoon showers and thunderstorms near the Cascades. Temperatures will begin to cool but remain above normal. OUTLOOK (MONDAY-WEDNESDAY) A weather system is forecast to move mainly into northern California, on Monday. Increasingly moist and unstable southerly flow aloft, and onshore transport winds, will lead to scattered showers with temperatures cooling back to near normal. There may also be some afternoon thunderstorms, mainly near the Cascades. A weak and transitory upper-level ridge will bring drying on Tuesday. Northwesterly flow aloft and onshore transport winds will continue the cooling trend. Increasing southwesterly flow aloft is forecast to drive a cold front onshore Wednesday with rain likely for most zones. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 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 in the 3000 to 4000 foot range for fair smoke dispersal conditions and southwesterly to southerly transport winds. 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. This will produce strong pressure gradients and brisk winds on Wednesday. Significant (for the time of year) rain spreads across the entire region during the morning hours. Expect high mixing heights for good smoke dispersal conditions. By Thursday the Gulf low splits and a portion moves to off Vancouver Island. This will continue to rotate moisture into the area. By Friday weak ridging aloft lowers mixing heights but there will still be enough moisture for showers. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY A deep surface low pressure area will track north-northeastward off the Oregon Coast on Wednesday bringing strong south winds and significant rain to the region. Rain spreads from west to east beginning in the morning and reaching the Cascade crest by mid-afternoon. Winds on the coast will peak in the 40 to 60mph range most areas while interior valleys will see peak winds generally on the order of 40mph. The snow level will drop to 3000-3500 feet overnight Wednesday night. Mixing heights will be 5000 feet or better for good smoke dispersal conditions. OUTLOOK (THURSDAY-SATURDAY) An upper level trough swings through early in the day Thursday. Showers then taper off, ending completely in the south. Cool air aloft will give good mixing heights and good smoke dispersal conditions. A system much weaker than Wednesday's will move through Friday for periods of rain and weak upper level troughiness continues for scattered showers into the weekend. Cooler surface temperatures will limit mixing heights somewhat Friday and Saturday. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height above 5000 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 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 except that just light southwest through northwest transport winds are likely in southwestern Oregon. With continued cool air aloft (freezing level down to 3500 feet in the north, 4500 feet in the south), 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 for periods of rain throughout 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. Mixing heights should be high enough throughout the outlook period for fair to good smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 FRIDAY A cold upper-level trough will remain over the entire Pacific Northwest. Another cold front will bring rain to most of western Oregon in the morning, followed by cool showery conditions in the afternoon and evening. Maximum temperatures will be 10-15 degrees below normal with accumulating snow at elevations above 3000 feet. High mixing heights will make for good smoke dispersal conditions. OUTLOOK (SATURDAY-MONDAY) The cold upper-level trough remains over Oregon Saturday with numerous showers and snow levels hovering near 3000 feet. The trough will slowly push east of the region Sunday and Monday with a progressively drier, more stable, and warmer northwesterly flow aloft. Monday looks mostly dry with only a chance of mainly afternoon mountain showers. The snow level should lift to around 6000 feet with maximum temperatures recovering to within about 5 degrees of normal. Cool air aloft will maintain high afternoon mixing heights, for good daytime smoke dispersal conditions, with early morning inversions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SUNDAY An unseasonably cold upper-level trough will begin pushing east of the region with the flow aloft drying and turning northwesterly. Clearing skies will lead to a cold morning, especially across the southern zones, with low-level temperature inversions forming. Skies should be partly to mostly cloudy with a few lingering showers, mainly over higher terrain. Maximum temperatures will warm several degrees, relative to Saturday, but remain well below normal. The snow level will lift to about 4000 feet in the afternoon. High afternoon mixing heights will make for good daytime smoke dispersal conditions. OUTLOOK (MONDAY-WEDNESDAY) The upper-level trough will push well east of the region by Monday with west-northwesterly flow aloft over western Oregon. Partial clearing and light winds will allow morning low-level temperature inversions to form, so residual smoke may be trapped near the ground. High afternoon mixing heights will provide fair to good daytime smoke dispersal conditions with increasing onshore transport winds. A weakening weather system is forecast to bring increasing clouds Monday afternoon with a slight chance of a light shower by Monday evening. The snow level is forecast to lift to around 6000 feet with maximum temperatures recovering to within about 5 degrees of normal. A strong southwesterly jet stream is forecast to direct another cold front onshore Tuesday with rain spreading back across all of western Oregon. Another upper-level trough will bring showers to the region Wednesday with snow levels dropping below 5000 feet. High mixing heights and brisk transport winds should make for good smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 MONDAY Weak upper level ridging ahead of an upper low west of the Queen Charlotte Islands will be the main weather feature of the day. Low level flow will be onshore for partly cloudy skies, but generally dry weather. Maximum mixing heights should be above 5000 feet for good smoke dispersal conditions. OUTLOOK (TUESDAY-THURSDAY) A short wave rotates around the upper level low pushing a weak front into the region for renewed precipitation on Tuesday. Expect fair to good smoke dispersal conditions. On Wednesday the upper low elongates north to south with a moist southerly flow increasing over the region. This will keep showers going into Thursday. On Thursday the upper low drops southward to off the Oregon coast. Expect fair to good smoke dispersal conditions throughout the outlook period. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 TUESDAY An upper level low remains about 6000 miles west of Vancouver Island on Tuesday. Counter clockwise flow around that low drives a Pacific weather system mainly into northern California but enough moisture spreads northward for periods of rain throughout the region. Mixing heights will be high enough for fair to good smoke dispersal conditions. Transport winds will be generally south to southeast except light and variable in the northern Cascades. OUTLOOK (WEDNESDAY-FRIDAY) The upper low elongates on a NW/SE axis but remains offshore on Wednesday. Upper flow will be from the south or southeast across Oregon. There will be enough moisture for scattered showers, but by evening they should be mainly over the cascades. By Thursday the upper low consolidates off the southwest Oregon coast. Moisture continues to stream around the low and spread south to north across the region. The low finally drifts east and a drier northerly flow sets up across the region. Expect dry weather, and with some sunshine, warmer temperatures. Smoke dispersal conditions should remain fair to good throughout the outlook period. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 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. Most showers will be in the southern portion of the region, but showers cannot be ruled out anywhere. Cool air aloft and daytime heating will help to destabilize the atmosphere in the afternoon for an increased chance of showers 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. Northwest Oregon will see some stabilization and mixing heights will be high enough for only fair smoke dispersal conditions, but southern zones should see a continuation of good conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 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 5000 feet. OUTLOOK (FRIDAY-SUNDAY) The upper-level trough axis is forecast to shift east of the Cascades Friday with the flow aloft turning northerly and beginning to dry out. Showers will taper off with some afternoon clearing, especially south. Maximum temperatures will remain well below normal with the snow level staying near 5000 feet. Cool air aloft will maintain good daytime smoke dispersal conditions. A transitory and weak upper-level ridge is forecast to bring dry weather to western Oregon Saturday and much of Sunday. That will lead to overnight temperature inversions, but daytime smoke dispersal conditions will likely remain fair to good. Another weather system is slated to come onshore Sunday night with a renewed chance of rain, mainly north. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 FRIDAY An upper-level trough axis is forecast to shift over western Oregon in the pre-dawn hours and east of the Cascades by midday. The flow aloft will switch from southeasterly, ahead of the trough axis, to northwesterly in its wake. Ample moisture will continue to circulate into the northern zones to produce showers or areas of rain. Meanwhile, showers will taper off across the southern zones with some afternoon clearing. Maximum temperatures will remain well below normal with the snow level staying near 5000 feet. Cool air aloft will maintain good daytime smoke dispersal conditions. OUTLOOK (SATURDAY-MONDAY) A transitory and weak upper-level ridge is forecast to bring a drying northwesterly flow aloft on Saturday. Northern zones may still pick up a little early morning rain with dry conditions prevailing across all zones by the afternoon. Temperatures will recover close to normal in the southern zones but stay well below normal in the north. Clearing skies will lead to cold overnight temperatures Saturday night with inversions trapping residual smoke near the ground. Most of Sunday will remain dry with some sunshine and fair to good daytime smoke dispersal conditions. Temperatures will rebound to near normal across the northern zones and to slightly above normal in the south. Clouds and rain will spread from northwest to southeast across the region late Sunday and early Monday. Monday will likely be mostly cloudy and cooler with some light rain in the north and a chance of showers south. 2.

SMOKE MANAGEMENT FORECASTS WILL RESUME ON MONDAY, MAY 31ST. 1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SATURDAY As a strong upper-level trough finally exits to the east, it will rotate one last disturbance southward across northern and eastern Oregon. That will keep skies generally cloudy over the northern and eastern zones, through the morning, with a chance of some lingering light rain. Skies will likely start out partly cloudy across the southern zones. All areas will see skies slowly clear during the afternoon, as a transitory and weak upper-level ridge brings a drying northwesterly flow aloft to the region. Temperatures will recover to near normal in the southern zones and to within about 5 degrees of normal in the north. Cool air aloft and daytime heating will provide fair to good afternoon smoke dispersal conditions. Continued clearing skies will lead to cold overnight temperatures with inversions trapping residual smoke near the ground. OUTLOOK (SUNDAY-TUESDAY) Most of Sunday will remain dry with increasing clouds and fair to good daytime smoke dispersal conditions. Temperatures will rebound to near normal across the northern zones and to slightly above normal in the south. A weak weather system is forecast to bring back a chance of light rain Sunday night and Memorial Day, mainly for the northern zones, along with slightly cooler temperatures. On Tuesday, onshore flow will keep skies mostly cloudy, west of the Cascade crest, with a chance of showers, mainly north. Down-sloping flow will clear skies east of the Cascade crest. Temperatures will be slightly below normal across all zones. Daytime smoke dispersal conditions should remain fair to good. 2.

NORMAL WEATHER OPERATIONS WILL RESUME ON MONDAY, MAY 31ST. 1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SUNDAY A weak and transitory upper-level ridge will move east of the region with increasing westerly flow aloft. The latest computer model guidance shows enough moisture in the flow for a chance of sprinkles, or very light rain, across the northern zones, but the southern zones should stay dry with increasing clouds. Temperatures will rebound to near normal across the northern zones and to slightly above normal in the south. Smoke dispersal conditions will be fair to good. OUTLOOK (MONDAY-WEDNESDAY) A weak weather system is forecast to come onshore Memorial Day with light rain likely across the northern zones and a chance of rain south. Temperatures will cool back below normal north and to near normal south. Smoke dispersal conditions will remain fair to good. On Tuesday, a flat and transitory upper-level ridge will turn the flow aloft northwesterly with some drying and stabilizing of the air mass. Onshore flow will hold lots of marine clouds west of the Cascade crest, with a slight chance of showers, mainly north. Down-sloping flow should keep skies just partly cloudy east of the Cascade crest. Temperatures will be slightly below normal across all zones. Daytime smoke dispersal conditions should be fair to good, but transport winds will be light. The flow aloft is forecast to turn westerly Tuesday night and Wednesday. A Pacific frontal system will likely spread rain across the northern zones with a chance of rain south. Transport winds will increase, with a significant southerly component. Afternoon mixing heights will not be as high on Wednesday, especially north, due to warming aloft and clouds preventing surface heating. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 TUESDAY 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 cloudy to mostly cloudy and temperatures generally 7 to 9 degrees below average for the time of year. This will keep mixing heights down and limit smoke dispersal conditions to fair to good in the north and only fair in the south. OUTLOOK (WEDNESDAY-FRIDAY) 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 spreading moderate rain eastward. Smoke dispersal conditions will be fair to good. On Thursday the southwest flow aloft continues and expect to be between weather systems but with still 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. This is a windy weather pattern so expect a generally rainy and windy day throughout the region. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height below 500 ft early rising to 1800 - 2800 ft by late morning. Transport wind light and variable.
