DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 MONDAY A fairly active cold front reaches the coastline early Monday morning slowly spreading rain eastward across Oregon. The rain will change to showery weather by afternoon as the front passes east. Transport winds will be southwesterly ahead of the front but switch to northwesterly behind. The shifting winds mean a larger "downwind" sector and may limit burning in the north coast range. Smoke dispersal conditions should be fair to good. EXTENDED OUTLOOK (TUESDAY - THURSDAY) The upper trough associated with Monday's front moves east Tuesday and higher pressure builds offshore. This will lead to drying but not before overnight showers Monday night into Tuesday morning bring snow down to about 3500 feet. Transport winds should be generally north-northwesterly and smoke dispersal conditions fair to good. The upper ridge axis moves directly over western Oregon Wednesday morning. This will suppress mixing heights and smoke dispersal conditions over portions of the Cascades will drop to marginal, with fair conditions likely elsewhere. A thermal trough builds offshore but then moves eastward during the day. Thus transport winds will be offshore early but shift onshore later in the day. Units that benefit from an easterly component to transport winds may see an opportunity if they can be lit and finished fairly early. By Thursday a weak upper trough moves over the region as the upper ridge moves east. Mixing heights improve and transport winds will have a westerly component with southwesterly transports in the north and northwesterly transport winds in the south. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 TUESDAY The upper trough that brought rain to portions of Oregon on Monday moves east on Tuesday while an upper level ridge builds to the west. The air aloft will still be cool enough to allow for high afternoon mixing heights and thus good smoke dispersal conditions. Transport winds will be generally northwesterly over the north coast range but elsewhere expect northerly winds and a good opportunity for units that are difficult to burn on the frequent southwesterly winds this time of year. OUTLOOK (WEDNESDAY - FRIDAY) The upper ridge begins the day Wednesday along the coastline but by evening has drifted eastward to over eastern Washington and Oregon. A thermal trough builds out of California and to offshore of southwest Oregon early, but shifts inland as the ridge aloft shifts. Thus expect some offshore flow early but transport winds will turn onshore during the day. There is some model difference in timing of the wind shift but best estimate now is late morning. Wednesday will be a warm day, the freezing level should approach 10,000 feet. Temperatures in the north will be 2-8 degrees above average and 6-12 degrees above average in the south. The upper ridge has shifted to over western Montana by Thursday morning and a weak upper trough moves into Washington. An associated cold front clips northwest Oregon for a slight chance of rain there, but elsewhere look for just middle and high clouds. The trough does support some instability for good afternoon mixing heights and good smoke dispersal conditions. Transport winds will be onshore or westerly with mostly southwesterly flow in the north and northwesterly flow in the south. Friday an upper low moves down the southeast Alaska/British Columbia coastline. Mid-level warming with the southwest flow ahead of the low suppresses mixing heights somewhat and smoke dispersal conditions will only be fair for the north coast and fair to good elsewhere. Surface temperatures drop to near or slightly below average and transport winds will be mostly southwesterly for northern zones and west-northwesterly for southern coastal areas. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY An upper level ridge drifts eastward across the region on Wednesday. The axis of the ridge is near the coast early in the morning but by evening lies along a line from eastern Washington to eastern Oregon. Warm air aloft suppresses mixing heights and keeps smoke dispersal conditions only in the fair category many areas. Surface temperatures will be 5 to 7 degrees above average in northern interior sections while southern interior valleys will see temperatures as much as 8 to 12 degrees above the mean. A surface thermal trough is along the coast during the early morning hours but shifts inland by late morning, then to over the Cascades by early evening. Shifting winds may pose problems as the trough axis moves through. Expect a generally light northeast through easterly transport with some east-southeast winds in the southern interior zones. These will shift to light northwesterly following the passage of the thermal trough. OUTLOOK (THURSDAY - SATURDAY) The upper ridge shifts to the northern plains on Thursday as a weak upper trough moves across the Pacific Northwest. Moisture is limited. Northwestern Oregon could see a few sprinkles, otherwise look for just mid and high clouds. Temperatures in northern sections fall back to near average in the north but are still at plus 5 to 10 degrees in the southern interior. Mixing heights recover a bit and smoke dispersal conditions will be mostly fair to good. Transport winds will be north or northwesterly. A generally zonal or west to east flow aloft prevails on Friday. Low level transport winds will be generally southwesterly in the northern sections, while southern zones will see a northwesterly transport flow. Smoke dispersal conditions remain fair to good. Little change in the broad upper scale flow for Saturday is likely, but a weak impulse in the flow should bring some light rain to northwestern Oregon. Elsewhere look for just an increase in mid and high level cloudiness. Surface temperatures cool to 6-10 degrees below average and transport winds should tend toward southwesterly. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 THURSDAY An upper-level ridge is forecast to flatten and shift eastward, to over the northern Rockies, as a weak upper-level trough moves across the Pacific Northwest. Expect skies to start out mostly cloudy north and partly cloudy south, with slow afternoon clearing. Northern zones could see a few light showers, especially early along western-facing slopes. Onshore transport winds will cool temperatures in northern and coastal sections back to near average, but the southern interior will still be 5 to 10 degrees warmer than normal. Afternoon mixing will be fair to good with west to northwesterly transport winds. OUTLOOK (FRIDAY-SUNDAY) A westerly flow aloft is forecast for Friday, with the region between storm systems. Transport winds will be generally southwesterly over the northern sections and northwesterly over the southern zones. Another weak weather system will approach the coastline in the afternoon. Increasing clouds will hold temperatures close to Thursday's highs with fair to good afternoon mixing. A strengthening westerly jet stream will direct another cold front across the Pacific Northwest Friday night, with a cool upper-level trough moving onshore Saturday. Precipitation will be limited to northern zones early Saturday but should increase in coverage Saturday afternoon and evening. The snow level will drop to 4000 feet north and to 6000 feet south late. High temperatures will cool to 5-10 degrees below average north and to near normal south. Transport winds will me mostly southwesterly over the northern zones and more westerly over the southern zones. Cooling aloft will make for fair to good afternoon mixing. By Sunday, another unseasonably cold upper-level trough will make camp over the Pacific Northwest. Rain and snow will be widespread with precipitation totals over .10 inches common.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 FRIDAY A strengthening westerly jet stream will push another weather system onshore late in the day. Clouds will increase across all zones with a chance of sprinkles or light rain north. Northern and coastal temperatures will be near to slightly below normal, while the southern interior remains a few degrees above normal. Transport winds will remain onshore with fair mixing. OUTLOOK (SATURDAY-MONDAY) Precipitation should be limited to northern zones early Saturday, with only a slight chance of light rain south. However, showers will increase in coverage Saturday afternoon and evening, as an impressive upper-level trough comes onshore. The snow level will drop to 4000 feet north and to 6000 feet south late. High temperatures will cool to 5-10 degrees below average north and to near normal south. Cooling aloft will improve mixing with continued onshore transport winds. By Sunday, an unseasonably cold upper-level trough is forecast to make camp over the Pacific Northwest. Rain and snow showers will be numerous with widespread precipitation totals over .10 inches and some areas picking up over .25 inches. The snow level will drop to 3500-4500 feet by evening. Cold air aloft should make for fair to good mixing with onshore transport winds turning more northwesterly. On Monday, the upper-level trough is forecast to drop southeastward, to over Nevada, with a drier northerly flow aloft developing over Oregon. Skies will begin to clear, but cool surface temperatures and some warming aloft will make for only fair smoke dispersal conditions. Transport winds will likely turn northerly. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SATURDAY A Pacific cold front will move across western Oregon Friday night and early Saturday, followed by an impressive upper-level trough. Expect generally cloudy skies with rain north and areas of light rain south in the morning. The rain will turn to showers by late-morning, with increasing showers in the afternoon and evening. Precipitation totals could locally exceed one-half inch north, over higher terrain, with amounts mostly less than one-quarter of an inch south. The snow level will drop to 4000 feet north and to 6000 feet south late. High temperatures will be 5-10 degrees below normal. Cooling aloft will improve mixing with generally west to southwest transport winds. OUTLOOK (SUNDAY-TUESDAY) By Sunday, the unseasonably cold upper-level trough is forecast to move directly over the Pacific Northwest. Rain and snow showers will be numerous with widespread precipitation totals ranging from around one-tenth of an inch to more than one-quarter of an inch. The snow level will drop to 3500-4500 feet by evening, as the showers begin to taper off. Cold air aloft should make for good mixing with onshore transport winds veering to northwesterly. On Monday, the upper-level trough is forecast to drop southeastward, to over Nevada, with a drier north-northeasterly flow aloft over Oregon. Look for decreasing showers, with clearing skies, but cool surface temperatures and some warming aloft will lower mixing heights. Transport winds will turn more northerly. Tuesday looks dry and warmer, as a transitory upper-level ridge moves onshore and over Oregon. Skies should turn mostly sunny, after areas of morning fog and low clouds. Afternoon temperatures will recover to above normal, with slightly higher mixing heights and fair smoke dispersal conditions. Transport winds will be light and turn onshore in the afternoon. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 - Issued 7-days-a-week through the spring burning season - SUNDAY An unseasonably cold upper-level trough is forecast to move over the Pacific Northwest. Rain and snow showers will be widespread with precipitation totals ranging from around one-tenth of an inch to more than one-quarter of an inch. The snow level will drop to 3000-4000 feet with surface temperatures about 10 degrees below average. Cold air aloft should make for good mixing with onshore transport winds veering to northwesterly. OUTLOOK (MONDAY-WEDNESDAY) On Monday, the upper-level trough is forecast to drop southeastward, to over Nevada, with a drier north-northeasterly flow aloft over Oregon. Look for decreasing showers, with partial clearing. Surface temperatures will remain well below normal, with minor warming aloft leading to slightly lower afternoon mixing heights. Transport winds will turn mostly northerly. Tuesday looks dry and significantly warmer, as a transitory upper-level ridge moves onshore and over Oregon. Residual low-level moisture may lead to areas of brief morning valley fog or low clouds, with skies becoming mostly sunny. After a chilly morning, with poor mixing, more surface heating will improve afternoon smoke dispersal conditions to fair to good. Daytime highs should recover to near or slightly above normal. Light mostly northerly morning transport winds will turn northwesterly in the afternoon. The upper-level ridge is forecast to shift eastward, to over Idaho, by Wednesday morning, with an increasing southwesterly flow aloft over Oregon. The latest computer guidance is forecasting a cold front to spread rain onshore, around midday, and across western Oregon by evening. Ahead of the cold front, some sunshine should help temperatures warm to near normal north and above normal south. Good mixing is expected for eastern zones, which will likely see some filtered sunshine, but mixing heights may be slightly suppressed by cloud-cover over the coast range. Southwesterly morning transport winds should veer to more westerly by late-afternoon. Afternoon rainfall amounts should range from one-tenth to one-quarter of an inch north with most southern zones picking up less than one-tenth of an inch. The snow level will drop to about 4500 feet north and 5500 feet south late. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 MONDAY A very deep (for this time of year) upper low is centered over the Oregon/Idaho/Nevada border early in the day. It pulls slowly south during the day and by evening is centered over Wendover, Utah. As the low moves away weak upper ridging builds offshore. With stabilization of the atmosphere showers end early and the day should be mostly dry. Mixing heights will be suppressed but smoke dispersal conditions should be generally good. Low level transports will be generally light northwest veering to more northerly with height. EXTENDED OUTLOOK (TUESDAY - THURSDAY) Tuesday the ridge builds and moves over the region for dry weather. Onshore flow at low levels will keep skies partly to mostly cloudy. With warming aloft but surface temperatures only recovering to near average mixing heights will be further suppressed and smoke dispersal conditions will only be marginal to fair. Transport winds will be light northeasterly shifting to light northwesterly during the day. On Wednesday the ridge moves east as yet another deep upper level low moves slowly southeastward in the Gulf of Alaska and begins to affect the Pacific Northwest. This low will be a major weather feature for several days. A Pacific cold front associated with the low will move in by Wednesday afternoon. Healthy rainfall for May is likely, with up to a quarter of an inch in the north and lighter amounts south. Surface temperatures remain near average and with cooling aloft maximum mixing heights improve. Low level transport winds will be mostly northwesterly backing to southwesterly with height. Friday sees a broad upper low centered about 200 miles west of Vancouver Island with southwesterly flow aloft over the region. Post frontal showers continue through the day and surface temperatures will be anywhere from 5 to 10 degrees below average for the time of year. Mixing heights should climb to 5000 feet or above, however. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 1300 - 2300 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 - Issued 7-days-a-week through the spring burning season - SUNDAY An unseasonably cold upper-level trough is forecast to move over the Pacific Northwest. Rain and snow showers will be widespread with precipitation totals ranging from around one-tenth of an inch to more than one-quarter of an inch. The snow level will drop to 3000-4000 feet with surface temperatures about 10 degrees below average. Cold air aloft should make for good mixing with onshore transport winds veering to northwesterly. OUTLOOK (MONDAY-WEDNESDAY) On Monday, the upper-level trough is forecast to drop southeastward, to over Nevada, with a drier north-northeasterly flow aloft over Oregon. Look for decreasing showers, with partial clearing. Surface temperatures will remain well below normal, with minor warming aloft leading to slightly lower afternoon mixing heights. Transport winds will turn mostly northerly. Tuesday looks dry and significantly warmer, as a transitory upper-level ridge moves onshore and over Oregon. Residual low-level moisture may lead to areas of brief morning valley fog or low clouds, with skies becoming mostly sunny. After a chilly morning, with poor mixing, more surface heating will improve afternoon smoke dispersal conditions to fair to good. Daytime highs should recover to near or slightly above normal. Light mostly northerly morning transport winds will turn northwesterly in the afternoon. The upper-level ridge is forecast to shift eastward, to over Idaho, by Wednesday morning, with an increasing southwesterly flow aloft over Oregon. The latest computer guidance is forecasting a cold front to spread rain onshore, around midday, and across western Oregon by evening. Ahead of the cold front, some sunshine should help temperatures warm to near normal north and above normal south. Good mixing is expected for eastern zones, which will likely see some filtered sunshine, but mixing heights may be slightly suppressed by cloud-cover over the coast range. Southwesterly morning transport winds should veer to more westerly by late-afternoon. Afternoon rainfall amounts should range from one-tenth to one-quarter of an inch north with most southern zones picking up less than one-tenth of an inch. The snow level will drop to about 4500 feet north and 5500 feet south late. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 TUESDAY An upper level ridge will lie southwest to northeast on an axis from about 900 miles west of Los Angeles to southern British Columbia early in the day on Tuesday. The ridge will drift eastward during the day providing dry weather and sunshine to the region. Transport winds will be light and generally northerly. Northwest Oregon will see a slight north-northwesterly transport and southwest coastal areas will see a slight north-northeasterly wind. With the ridge, subsidence will suppress mixing heights a bit but smoke dispersal conditions will be fair to good during the afternoon hours. OUTLOOK (WEDNESDAY - FRIDAY) The upper ridge continues east and the Pacific Northwest starts to come under the influence of an upper level low centered about 250 miles west of the Queen Charlotte Islands on Wednesday morning. This low supports a fairly active cold front that will come onshore during the afternoon and spread rain to the Cascade crest by early evening. Cooler temperatures aloft a the lack of subsidence will help maximum afternoon mixing heights to climb to near 5000 feet for good smoke dispersal conditions. Transport winds will be mostly southwesterly or southerly. The upper level low rotates to about 350 miles west of Vancouver Island by Thursday. Expect post frontal showers but also sun breaks during the day. Temperatures will range from four to seven degrees below average. Some instability with the cool air aloft will provide for good smoke dispersal conditions. Transport winds will be generally southwest through south. Friday sees the upper low about 350 miles west of the mouth of the Columbia River. Wind flow aloft will be southerly. West of the Cascades expect a rather flat pressure gradient for light and variable winds. But afternoon mixing heights will remain high. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY The upper ridge that brought sunshine to much of the state Tuesday moves east on Wednesday. In the meantime an upper level low off the west coast of North America becomes the major factor in Pacific Northwest weather. The low supports a Pacific cold front that will reach the north coast by late morning and spread rain to the Cascade crest by late afternoon. Rainfall amounts of around a quarter of an inch are possible in northern sections while southern locations will see about a tenth of an inch. Temperatures will be five to 10 degrees below average for mid May. Freezing levels will drop in the north and any precipitation falling by late Wednesday could be show as low as 2500 feet there. Warm air streaming north at middle levels ahead of the front will limit mixing heights although after frontal passage cooler temperatures aloft will push maximum mixing heights to 5000 feet. Transport winds will be mostly south-southwesterly ahead of the front but shift to northwesterly behind. OUTLOOK (THURSDAY - SATURDAY) The upper low is centered about 300 miles west of Vancouver Island Thursday morning drifting slowly southward. Moisture will be limited over western Oregon, but some post frontal showers are likely. With cool air aloft mixing heights should be quite high and transport winds will be brisk southerly or southwesterly most areas for good smoke dispersal conditions. The upper low moves to about 500 miles west of the mouth of the Columbia River by Friday. This is far enough offshore that most precipitation with this low should remain offshore. There may be some mountain showers during the afternoon but otherwise expect dry weather for the region. Mixing heights should stay high but transport winds will be light north or northwesterly. By Saturday the low aloft will be about 350 miles west of Brookings but slowly rotating toward northern California. This will bring an increasing chance of rain to western Oregon. While mixing heights will be high, transport winds will be light and variable most areas. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 2500 - 3500 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 THURSDAY An upper level low pressure area will spin off the coast Thursday and Friday then open up and move over Oregon and Washington over the weekend. There will still be some post frontal showers over western Oregon on Thursday but the main low center will stay well offshore and moisture will be limited during the day. Surface temperatures will range five to ten degrees below average, but temperatures aloft will be cool as well so maximum mixing heights should be quite high. Transport winds in the northern zones will be south or southwesterly and southern areas should see a west or northwesterly flow. EXTENDED OUTLOOK (FRIDAY - SUNDAY) On Friday the upper low remains far enough offshore such that there is very little moisture available for precipitation. Thus expect dry weather and with southerly aloft temperatures recover to near average. Maximum afternoon mixing heights will remain fairly high and smoke dispersal conditions should be generally fair to good with a mostly north-northeast to east-northeast transport flow. Saturday showers develop as the upper low opens up and rotates into the area as an upper level trough. Smoke dispersal conditions remain fair to good but transport flow will be light, generally northwest through southwest. Sunday the upper trough is directly over the area. Expect numerous showers and quite cool weather with temperatures from 10 to 15 degrees below average for mid May. Mixing heights should climb to around 4000 feet and transport winds will become south or south-southwest during the day. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 - Issued 7-days-a-week through the spring burning season - FRIDAY An upper-level low-pressure center will produce a warming south-southwesterly flow aloft over Oregon but remain far enough offshore to greatly limit the threat of showers. With only partly cloudy skies and warming aloft, daytime temperatures should climb to just above normal. Afternoon heating will destabilize the air mass enough to produce some increase in cloud-cover and possibly a few showers, mainly over higher terrain. Warming aloft may slightly suppress maximum afternoon mixing heights, but daytime smoke dispersal conditions should be generally fair to good. Transport winds will begin offshore but are forecast to quickly turn back onshore across the central and southern zones. More persistent offshore transport winds are likely across the extreme northern zones. OUTLOOK (SATURDAY-MONDAY) On Saturday, the offshore upper-level low-pressure system is forecast to slowly move closer to the southern Oregon coast. Increasing south-southeasterly flow aloft will direct more moisture into the region. Afternoon heating will destabilize the air mass, with more widespread shower development likely, especially over higher terrain. Weak onshore flow and increasing clouds will limit surface warming. Maximum temperatures will drop back below normal. The snow level will drop to about 6-7000 feet in the afternoon. Cooling aloft should help to maintain at least fair smoke dispersal conditions. The upper-level trough is forecast to come onshore Sunday and Monday, with a very cool and moist air mass over Oregon. Expect numerous showers with a chance of afternoon thunderstorms each day. The snow level should drop to 3-4000 feet with maximum surface temperatures 10-15 degrees below average. Cooling aloft will make for fair to good afternoon mixing with mostly southwesterly transport winds. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SATURDAY An offshore upper-level low-pressure system is forecast to slowly move closer to the southern Oregon coast. Increasing southeasterly flow aloft will direct more moisture into the region. Afternoon heating will destabilize the air mass, with shower development likely, especially south and over higher terrain. Increasing clouds will limit surface warming and mixing. Maximum temperatures should be about 5 degrees below normal. The snow level will only drop to about 6-7000 feet. Afternoon mixing heights will be mostly below 3000 feet, which will combine with very light onshore transport winds to make for just marginal smoke dispersal conditions. OUTLOOK (SUNDAY-TUESDAY) The upper-level trough is forecast to come onshore Sunday and make camp over the Pacific Northwest, slowly weakening Monday and Tuesday. That will park a very cool and moist air mass over Oregon. Expect numerous showers Sunday with a chance of thunderstorms, mainly south. Showers will continue Monday and Tuesday but will be on the decrease. The snow level should drop to 3-4000 feet. Maximum surface temperatures will start out about 10-15 degrees below average, on Sunday, before recovering to about 5 degrees below normal by Tuesday. Colder air aloft will make for fair to good afternoon mixing with onshore flow. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SUNDAY An upper-level low-pressure system is forecast to finally come onshore just south of the Oregon/California border. Southeasterly flow aloft will continue, with a substantial increase in the amount of moisture circulating into Oregon. Look for widespread showers and/or areas of steady rain and mountain snow. There is also a chance of a thunderstorm, mainly over the southern Cascades and Siskiyous. The snow level will lower to 3-4000 feet. Significant precipitation is forecast, but it difficult to predict where the greatest totals will be. Amounts should range from .25" to over .50". Maximum temperatures should be 10-15 degrees below mid-May normals. Although southeasterly flow aloft tends to suppress mixing heights, cooling aloft will combine with what little daytime heating there will be to improve afternoon smoke dispersal conditions, especially south. Look for increasing onshore transport winds in the afternoon. OUTLOOK (MONDAY-WEDNESDAY) On Monday, the upper-level low-pressure system is forecast to open into a general trough, with its axis along the coast. The flow aloft will veer from southeasterly to southwesterly, which is a more stable but still fairly moist pattern. Expect mostly cloudy skies and scattered showers. The snow level will remain at 3-4000 feet, with surface temperatures about 10 degrees below normal. Maximum mixing heights should climb above 5000 feet with weakening onshore transport winds veering to northwesterly. Another weather system is forecast to feed into the general trough over the Pacific Northwest, on Tuesday, with the main energy directed into Northern California and southern Oregon. Skies may start out partly sunny, but clouds will increase in the afternoon with showers likely, mainly south. The snow level will only rise to 4-5000 feet, with surface temperatures 5-10 degrees below normal. Cool air aloft and increasing onshore flow will provide fair to good smoke dispersal conditions. The upper-level trough appears as if it will finally weaken and shift eastward on Wednesday. A drier northwesterly flow aloft will taper off the shower activity with some afternoon clearing. The snow level will rise to 5-6000 feet with surface temperatures recovering to near normal. Afternoon mixing heights should rise above 5000 feet with light north-northwesterly transport winds. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 THURSDAY The upper-level trough that has been bringing cool and damp conditions to the region for the past several days will continue to weaken and drift southeastward. It is forecast to stretch from South Dakota to southern California by the afternoon. Meanwhile, a weak ridge of high pressure will build just offshore and turn the flow aloft north-northwesterly over Oregon. Continued drying and warming of the air mass will lift the freezing level to 8-9000 feet. After a chilly early morning, ample afternoon sunshine should warm maximum temperatures to near or slightly above average. It will still be cool enough aloft for fair to good daytime mixing. Transport winds may be northeasterly, in the morning, across the southern zones, which could provide some coastal-zones burning opportunities. Look for northerly transport winds in the northern zones. Transport winds should become northwesterly across the northern zones and north to northwesterly across the southern zones by the afternoon. OUTLOOK (FRIDAY-SUNDAY) The upper-level ridge axis is forecast to move onshore Friday morning and slowly drift eastward, to near to Idaho border, by evening. Light morning transport winds should increase from the northwest during the late-morning and afternoon. Maximum temperatures will be 5 to 10 degrees above average, which should lift afternoon mixing heights above 4000 feet. On Saturday a weak upper-level trough is forecast to come onshore, along with a surface cold front. That should bring a return of mostly cloudy skies with at least a chance of a few showers, mainly over higher terrain. Maximum temperatures will likely drop back to near or slightly below normal, with increasing northwesterly transport winds. Cooling aloft will promote fair to good afternoon mixing. Little change in the weather pattern is forecast for Sunday, with westerly flow aloft maintaining onshore flow, mostly cloudy skies, and a chance of a few showers. Temperatures will hover near normal with fair to good afternoon mixing and northwesterly transport winds. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 FRIDAY The strong upper-level trough that brought cool and damp conditions earlier this week dropped well southeast of Oregon on Thursday and will rotate northeastward, across the Northern Rockies and into the Northern Plains States, on Friday. Meanwhile, a weak ridge of high pressure is forecast to move onshore Friday morning and slowly drift eastward, to near to Idaho border, by evening. Look for partly cloudy skies with light morning transport winds increasing from the northwest during the afternoon. High temperatures will be 5 to 10 degrees above average, with good daytime mixing. OUTLOOK (SATURDAY-MONDAY) On Saturday a weak upper-level trough is forecast to come onshore, along with a surface cold front. That should bring a return of mostly cloudy skies with at least a chance of a few showers, mainly over higher terrain. Rainfall totals should be generally less than one-tenth of an inch. High temperatures will likely drop back below normal, with increasing northwesterly transport winds. Cooling aloft will promote fair to good afternoon mixing. Little change in the weather pattern is forecast for Sunday and Monday, with a moderately strong upper-level trough over the region maintaining onshore flow, mostly cloudy skies, and a chance of a few showers. Temperatures should remain slightly below normal with northwesterly transport winds becoming a bit more northerly by Monday, especially south. Daytime mixing will be fair to good. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SATURDAY A weak upper-level trough is forecast to come onshore in the early morning, along with a surface cold front. That will strengthen the onshore flow, bringing a return of mostly cloudy skies, some light showers, and cooler temperatures. Rainfall totals should generally be less than one-tenth of an inch. High temperatures will likely drop back below normal, with increasing northwesterly transport winds. Cooling aloft will promote fair to good afternoon mixing. OUTLOOK (SUNDAY-TUESDAY) Little change in the weather pattern is forecast for Sunday and Monday, with a moderately strong upper-level trough over the region maintaining onshore flow, mostly cloudy skies, and a chance of showers. Temperatures should remain about 5 degrees below normal with northwesterly transport winds becoming a bit more northerly by Monday, especially south. Daytime mixing will be fair to good. The upper-level trough is forecast to weaken by Tuesday, as it moves off to the east. A cool but drier northwesterly flow aloft will slowly clear skies, as high temperatures return to near normal. Daytime mixing will remain fair to good. Light transport winds may turn offshore, especially across the southern zones. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SUNDAY An upper-level trough is forecast to extend from the Gulf of Alaska southeastward to over the Pacific Northwest. The second in a series of embedded weather disturbances will rotate onshore during the day. That will maintain strong onshore flow, mostly cloudy skies, and a chance of light showers, mainly north and over higher terrain. Rainfall totals should generally be less than one-tenth of an inch north, with only widely scattered showers south. High temperatures will likely be as much as 10 degrees below normal, with continued northwesterly transport winds. The snow level will drop to around 5000 feet north and 6000 feet south, with cool air aloft leading to fair to good afternoon mixing. OUTLOOK (MONDAY-WEDNESDAY) A moderately strong upper-level trough will rotate another embedded weather disturbance onshore Monday. This system looks to be a little stronger than the previous two, with generally cloudy skies and scattered showers expected across all zones. Rainfall totals will likely range from a few hundredths to around one-tenth of an inch, with the snow level dropping to near 4500 feet. High temperatures should remain about 6-10 degrees below normal with northwesterly transport winds. Daytime mixing will be fair to good. The upper-level trough is forecast to weaken by Tuesday, as it moves off to the east. A weak and transitory upper-level ridge will slowly clear skies, as high temperatures return to within 5 degrees of normal. Daytime mixing will remain fair to good, but onshore transport winds will become light. An impressive upper-level trough is forecast to approach the coastline on Wednesday, as a strengthening southwesterly jet stream directs an active cold front across the state. Measureable precipitation is likely for all zones with more than one-quarter of an inch locally possible. Temperatures will drop back below normal, with the snow level lowering to near 4000 feet late. Increasing southwesterly transport winds will make for fair to good smoke dispersal conditions. 2.
