DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY An upper level low remains in the Gulf of Alaska approximately 600 miles west of the Queen Charlotte Islands. Winds aloft over the Pacific Northwest will be from the west southwest and drive a Pacific weather front through the region during the day. This will produce significant rain for the area. Warm air streaming northward in advance of the front will suppress mixing heights a bit for just fair smoke dispersal conditions. OUTLOOK (THURSDAY-SATURDAY) The upper low will be in about the same position on Thursday but the region will be between weather systems for mostly cloudy skies but only widely scattered showers. Cooler air aloft will push afternoon mixing heights well above 5000 feet for good smoke dispersal conditions. A surface low will develop off the southern Oregon coast and track northeastward toward Washington Thursday night and into early Friday. This looks to be quite deep for this time of year and strong winds are likely with winds above 50mph on the coast and 25-35mph in the interior valleys. In addition significant rainfall is likely with this system as well. The rain will taper off late in the day and by Saturday weak surface high pressure builds to the north for drying and warmer temperatures. Smoke dispersal conditions will be good to excellent Thursday and Friday, but light and variable winds will limit smoke movement on Saturday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 THURSDAY An upper level low continues in the Gulf of Alaska producing a west-southwest flow over the Pacific Northwest. The flow is quite strong, especially for the time of year, with a 125mph plus jet stream cutting across the area at about 30,000 feet. However, during the day on Thursday the area will be between weather systems and while it will be generally dry I can't rule out a few widely scattered showers. A low is developing off the SW Oregon coast and this now looks like it will track toward NW Oregon during the day Thursday. This is a less favorable track for strong winds in Oregon. The system will bring rain however, with rain beginning in the southwest and spreading northward during the evening hours. Rain will be quite heavy overnight and into Thursday morning. After morning surface-based inversions mixing heights should climb to around 4-5000 feet for good smoke dispersal conditions. OUTLOOK (FRIDAY-SUNDAY) The heavy rain continues into Friday morning then slowly turns to showers and decreases. Mixing heights will provide fair to good smoke dispersal conditions. On Saturday surface high pressure begins to build but showers will continue, slowly decreasing during the day. At this point Sunday looks like a mostly dry day with partly cloudy skies. Mixing heights both Saturday and Sunday will be near or above 5000 feet for good smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 FRIDAY An unseasonably strong westerly jet stream will direct another potent Pacific storm across Oregon. Moderate to heavy rainfall is expected across all zones in the morning with steady rain becoming more showery in the afternoon. A surface low-pressure system is forecast to track across extreme northwestern Oregon and western Washington in the early morning and then rapidly move into northeastern Washington in the afternoon. It is not forecast to be a real strong low-pressure system, but the forecast track is favorable to bring brisk southerly winds to the coast and coastal range with breezy conditions extending eastward into the Cascades. Clouds and rain will keep temperatures well below normal, but the snow level is expected to stay above 6000 feet. High mixing heights and strong transport winds will make for good smoke dispersal conditions. OUTLOOK (SATURDAY-MONDAY) Saturday will be a break between storms, but the strong westerly jet stream will direct a weaker weather system across mainly the northern half of the state Sunday. Some drying is expected again on Monday with temperatures moderating to near normal. Daytime smoke dispersal conditions should be fair to good during the period, although transport winds will be light on Saturday. The long-range computer models show wet conditions possibly returning later next week. 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 SATURDAY The region will get a break from the moderate to heavy rains of the past couple of days, as a transitory upper-level ridge pushes an unseasonably strong westerly jet stream slightly north. High pressure will also build at the surface, resulting in light transport winds. Residual marine clouds will give way to at least partly sunny skies, which will help temperatures recover to near normal. Ventilation conditions will be poor in the morning but should improve in the afternoon, as mixing heights climb in response to daytime heating. OUTLOOK (SUNDAY-TUESDAY) The strong westerly jet stream will direct another, weaker, weather system across Washington and Oregon on Sunday. Light to moderate rainfall is possible again across the entire region, although rainfall amounts should not be as great as they were with the past two storms. Clouds and rain will cool surface temperatures back below normal. Some drying is expected on Monday with skies becoming partly to mostly sunny. Temperatures should be near normal. The next system is forecast to bring back a chance of rain by Tuesday afternoon and could also produce impressive rainfall totals from late Tuesday through Wednesday. High afternoon mixing heights will provide fair to good daytime smoke dispersal conditions during the outlook period. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SUNDAY The strong westerly jet stream that has already brought two soaking storms to the region will direct another wet weather system across Washington and Oregon. Significant rainfall is possible again across the entire region, although rainfall totals will generally be less than from the previous two storms. Clouds and rain will cool surface temperatures back below normal. Smoke dispersal conditions will be fair to good with moderately high mixing heights and onshore transport winds. OUTLOOK (MONDAY-WEDNESDAY) No major change to the overall weather pattern is expected. However, the region will get another brief break between storms on Monday, with skies becoming partly to mostly sunny in the afternoon. Temperatures should return to near normal. Yet another weather system is forecast to bring back a chance of rain by Tuesday afternoon with widespread light rain expected Tuesday night and Wednesday. The cool and damp weather pattern is forecast to continue at least through Friday. High afternoon mixing heights and strong onshore flow will provide fair to good daytime smoke dispersal conditions during the outlook period. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 MONDAY The weather system that brought rain to much of the Pacific Northwest Sunday is well to the east and dissipating by Monday. There will be slight ridging aloft and surface high pressure centered offshore. Skies will be generally partly cloudy with good mixing heights for generally fair to good smoke dispersal conditions. OUTLOOK (TUESDAY-THURSDAY) Weak high pressure aloft develops over the region Thursday. Expect partly cloudy skies. However, warmer temperatures aloft will stabilize the atmosphere and hold down afternoon maximum mixing heights for only marginal smoke dispersal conditions for the northwest zones and fair to good conditions elsewhere. Another weather system brings rain back to the area by early Wednesday. Amounts will be mostly less than three-tenths of an inch. Mixing heights will still be suppressed for just fair smoke dispersal conditions except for fair to good conditions in southeastern zones. Thursday will see scattered showers but cooler conditions aloft should improve smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 TUESDAY Upper level flow over the region will be generally west-southwest ahead of an upper level low pressure area about 600 miles offshore. Warm air streaming northward in the middle layers of the atmosphere will suppress mixing heights. Clouds will be on the increase during the day, but it looks like rain won't reach the south coast until late in day...spreading northward into northern sections by midnight. Amounts should be light. OUTLOOK (WEDNESDAY-FRIDAY) By Wednesday the upper level low will be about 100 miles west of Grays Harbor, Washington. Upper level flow will be from the southwest with enough moisture for periods of light rain. Slight cooling aloft will bump mixing heights a bit for generally fair smoke dispersal conditions. The upper low moves across northern Washington on Thursday with an upper trough sweeping across Oregon. This will keep periods of rain going. Subsidence aloft on the back side of the trough will hold mixing heights a little lower than Wednesday. By Friday the trough will be on an axis from northern Idaho to central Nevada and moving east. Flow aloft will be northerly. There will still be enough moisture for a chance of light rain. Friday transport winds should be steady and brisk from the north offering burn opportunities that may not have been available for quite some time with the persistent west or southwesterly pattern of recent days. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY An upper level low pressure area will move to off the Washington coast Wednesday. This will give southwesterly flow aloft to the region. A Pacific weather system embedded in that southwesterly flow ushers in rain beginning Tuesday evening and continuing throughout the day Wednesday. Amounts will range from about 1/10th of an inch near Medford to near 4/10ths of an inch in the northern coast range. Smoke dispersal conditions will be generally fair. OUTLOOK (THURSDAY-SATURDAY) The upper low weakens - the remaining trough slowly moves east across the Pacific Northwest. Expect showers off and on during the day. Some subsidence on the back side of the trough will help end the showers later in the day but also suppress mixing heights a bit. By Friday upper ridging develops in the eastern Pacific and most of the showers should be over. Transport winds will have a northerly component, perhaps offering burn opportunities that have not been present with the persistent southwesterly or westerly pattern of the past several days. Saturday should see dry and warmer weather. The warmer afternoon surface temperatures should push mixing heights to above 5000 feet for good smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 THURSDAY A cool upper-level trough will move over western Oregon in the morning and across eastern Oregon during the afternoon. Cold air aloft will drop the snow level to 4000 feet north and 5000 feet south with daytime heating helping to destabilize the air mass and maintain widespread shower activity. Temperatures will be well below normal. Smoke dispersal conditions will be fair to good with moderately high mixing heights and onshore transport winds. The flow aloft is forecast to slowly turn more northerly overnight, with the air mass stabilizing and drying. A few showers could linger into Friday morning. OUTLOOK (FRIDAY-SUNDAY) An upper-level ridge will build just offshore on Friday with the flow aloft drying and turning north-northwesterly. That will finally put an end to the long stretch of very wet weather with skies clearing and transport winds turning more northerly. Even with some June sunshine, cool air aloft will keep surface temperatures slightly below normal. Subsidence, associated with the building upper-level ridge, will likely cap afternoon mixing heights between 3000 and 5000 feet. The upper-level ridge will move over western Oregon Saturday and eastern Oregon Sunday for dry and warmer conditions. Transport winds will turn offshore with surface temperatures warming to above normal both days. Daytime heating should make for high afternoon mixing heights. Increasing southwesterly flow aloft may turn transport winds onshore late Sunday, especially north. 2. DISPERSION Zone 601-612 (North Coast Range and Cascades): MORNING Mixing height 2000 - 3000 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 FRIDAY A fairly weak upper-level ridge will build just offshore with the flow aloft drying and turning north-northwesterly. That will finally put an end to the long stretch of unseasonably wet weather. A few showers could persist through the morning, in the northern zones, with skies clearing across all zones during the afternoon. Transport winds will turn mostly northerly. Surface temperatures will warm to just slightly below normal. The air aloft will also be warming, which will likely cap afternoon mixing heights between 4000 and 5000 feet. Clearing skies will allow temperatures and mixing heights to quickly drop after sunset, so residual smoke may settle near the ground. OUTLOOK (SATURDAY-MONDAY) An upper-level ridge will move over western Oregon Saturday for dry and warmer conditions. Transport winds will turn offshore with surface temperatures warming to about 5-10 degrees above normal. A mostly dry cold front is forecast to push the northern portion of the ridge well east of the Cascades by Sunday afternoon. A return to onshore flow will likely cool northern zone temperatures a few degrees, but southern zones may see a few more degrees of warming with mostly northerly transport winds. Onshore flow is forecast to increase across all zones by Monday with temperatures cooling back to near normal south and to slightly below normal north. Marine low clouds will likely invade the inland northern zones Monday, west of the Cascade crest, with some drizzle or showers possible along mainly the western slopes of the northern coast and Cascade ranges. Mostly sunny skies are expected to continue across the southern and eastern zones. Daytime heating should yield high afternoon mixing heights Saturday and moderate to high mixing heights Sunday and Monday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SATURDAY An upper-level ridge will move over western Oregon Saturday for dry and warmer conditions. Transport winds will turn offshore with surface temperatures warming to about 5-10 degrees above normal. Daytime heating should yield high afternoon mixing heights. Clearing skies will allow temperatures and mixing heights to quickly drop off in the evening, with residual smoke staying near the ground. OUTLOOK (SUNDAY-TUESDAY) A mostly dry cold front is forecast to push the ridge east of the Cascades Sunday. A return to onshore flow will likely cool northern zone temperatures several degrees, with northerly transport winds holding southern zones temperatures close to Saturday's values. Onshore flow is forecast to increase across all zones Monday and Tuesday, as a weak upper-level trough comes onshore and turns the flow aloft southwesterly. Temperatures should cool back below normal north and to near normal south. Marine low clouds will likely invade the inland northern and central zones, west of the Cascade crest, with some drizzle or showers possible along mainly the western slopes of the northern coast and Cascade ranges. Skies will likely stay mostly sunny across the extreme southern and eastern zones, where transport winds remain more northerly.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SUNDAY A mostly dry cold front is forecast move onshore in the morning with the weak upper-level ridge sliding east of the Cascades. Patchy morning drizzle is possible along the western slopes of the northern coastal range with some marine clouds penetrating into the northwestern interior. Skies should remain mostly clear across the southern zones and east of the Cascade crest. As the weakening cold front sweeps across the region, increasing onshore flow will likely cool northern zone temperatures close to normal, with northerly transport winds holding southern zones temperatures close to Saturday's values. Daytime heating should yield moderately high afternoon mixing heights. OUTLOOK (MONDAY-WEDNESDAY) Onshore flow is forecast to strengthen during the outlook period, especially across the northern zones, as an upper-level trough comes onshore and stalls over Washington and Oregon. On Monday, temperatures will cool back below normal north and to near normal south. Further cooling is likely, across all zones, Tuesday and Wednesday. Considerable low clouds will push back across the northern and central zones, west of the Cascade crest, with a chance of drizzle or light showers at times. Skies will become at least partly cloudy across the southern zones, where transport winds will remain more northerly. The chance of light showers will extend southward, to the California border, by Wednesday. Daytime heating should yield moderately high afternoon mixing heights with brisk transport winds. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 MONDAY The upper ridge that brought sunshine to much of Oregon over the weekend moves east on Monday. The coastal low clouds of Sunday will penetrate interior valleys. This will hold temperatures down a few degrees. Except for some spotty drizzle along the coast and in the coast range conditions should remain dry. Transport winds will be generally northwesterly. Smoke dispersal conditions should be fair to good. OUTLOOK (TUESDAY-THURSDAY) An upper level low drops down the British Columbia coastline and across northwest Washington during the day Tuesday. This will increase the southwesterly flow aloft.

Relatively cool air aloft will destabilize the atmosphere and help push maximum mixing heights to above 5000 feet. Low level flow will be generally onshore or northwesterly during the day except more northerly transport winds are likely over the south coast range. OUTLOOK (WEDNESDAY-FRIDAY) The upper low moves southeast into southern Idaho on Wednesday. Cooler daytime temperatures will limit maximum mixing heights a bit but smoke dispersal conditions should be at least fair to good most areas. Expect a chance of light rain. By Thursday the upper level low will move east northeast into south-central Canada. Flow will continue mostly onshore but the rain will be ending during the day. Friday looks dry but cloudy. Mixing heights both Thursday and Friday should be fairly high yielding generally good smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY An upper level low pressure area continues to spin over the Pacific Northwest on Tuesday. Low level flow will be onshore for mostly cloudy skies. With the cool air aloft with the low scattered showers are likely, especially for the northern zones. Mixing heights will climb to three to four thousand feet most areas for fair to good smoke dispersal conditions. OUTLOOK (THURSDAY-SATURDAY) The upper level low dissipates Thursday but a broad trough remains over the region. Weak onshore flow continues most areas for partly to mostly cloudy skies and a continuing chance of showers. Smoke dispersal conditions will be good most areas. The trough remains for Friday but weakens and finally by Saturday weak ridging begins to build offshore. Showers are still possible although moisture will be very limited. High mixing heights should give good smoke dispersal conditions for the end of the week. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 3300 - 4300 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 THURSDAY The upper low that has been plaguing the Pacific Northwest the past few days weakens and moves east but upper troughiness remains over the region on Thursday. Low level flow will be onshore and skies will again be mostly cloudy most areas with a few scattered showers. Temperatures continue below average for the time of year. Mixing heights should push high enough during the afternoon for fair to good smoke dispersal conditions. OUTLOOK (FRIDAY-SUNDAY) A broad trough remains over the region throughout the outlook period. Low level flow will remain onshore most areas for plenty of clouds and a slight chance of showers. Moisture will be limited, but I can't rule out the chance of a shower for any day through the weekend. Cloud-cover will hold down temperatures west of the Cascade crest and the limited heating will keep maximum mixing heights down somewhat and occasionally smoke dispersion conditions may only be marginal, especially in the south coast range. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 FRIDAY A cool upper-level trough will remain over Washington and Oregon. Another disturbance will rotate into the trough, from off the southern British Columbia coastline, and take up residence just off the northern Oregon coast. That will maintain a cool and moist southwesterly flow aloft over Oregon with onshore flow in the transport layer, especially across the northern zones. Morning marine low clouds should be prevalent west of the Cascade crest, especially across the northern and central zones, with partial afternoon clearing. However, daytime heating will combine with cool air aloft and the approaching weather disturbance to destabilize the atmosphere and increase the chance of showers. There is even a chance of late afternoon and evening thundershowers, mainly near the Cascades. Temperatures will remain well below normal with moderately high afternoon mixing heights. OUTLOOK (SATURDAY-MONDAY) An upper-level disturbance will move onshore and over western Oregon Saturday with showers or areas of rain likely and well below normal temperatures. The disturbance will move over eastern Oregon Sunday with the shower threat decreasing. Considerable marine low clouds, west of the Cascade crest, should partially clear Sunday afternoon, but high temperatures will be remain well below normal with strong onshore flow at the transport level. The onshore flow will turn more northerly Monday, as a transitory upper-level ridge moves over Oregon. That will promote more afternoon clearing with temperatures recovering to only slightly below normal. Moderate to high afternoon mixing heights are expected during the outlook period. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SATURDAY A broad and cool upper-level trough will remain over Washington and Oregon. The center of an upper-level disturbance, embedded within the broad trough, will slowly sag southward just off the Oregon coast. The counterclockwise circulation around it will produce a moist and somewhat unstable south-southwesterly flow aloft over the state. Showers are likely with increasing onshore flow, at the transport level, cooling temperatures back to well below normal. Limited daytime heating, combined with cool air aloft, will yield moderately high afternoon mixing heights. The snow level will drop to as low as 6000 feet by evening. OUTLOOK (SUNDAY-TUESDAY) The center of the embedded upper-level disturbance will move over southwestern Oregon early Sunday and slowly progress eastward, to over southeastern Oregon, by Sunday evening. Considerable moisture will continue to wrap around the exiting upper-level disturbance, keeping skies mostly cloudy across western Oregon. The snow level will hover near 6500 feet, but showers will taper off later in the day, as the flow aloft turns northwesterly and begins to stabilize the air mass. Transport winds will slowly turn more northerly, especially across the southwestern zones. High temperatures will remain well below normal. A weak and transitory upper-level ridge will move over western Oregon Monday and drift eastward, to over eastern Oregon, on Tuesday. Progressively more sunshine will help temperatures recover to near normal by Tuesday. Transport winds will turn more northerly and perhaps offshore by Tuesday morning, even across the northern zones. That could present some burning opportunities for western zones. Moderate to high afternoon mixing heights are expected during the outlook period. 2.

Considerable moisture will continue to wrap around the exiting upper-level disturbance, keeping skies mostly cloudy across western Oregon. However, the chance of showers will be decreasing, as the flow aloft turns northwesterly and begins to stabilize the air mass. Onshore flow, at the transport level, will turn more northerly across the southwestern zones. High temperatures will remain well below normal. Cool low-level onshore flow and considerable marine clouds will combine to produce only marginal mixing heights for late spring. OUTLOOK (MONDAY-WEDNESDAY) A weak and transitory upper-level ridge will move over western Oregon Monday and drift eastward, to over eastern Oregon, on Tuesday. Progressively more sunshine will help temperatures recover to near normal by Tuesday. Transport winds will turn northerly Monday and Tuesday, in the north, and perhaps slightly offshore in the south. That could present some burning opportunities for western zones. A weak upper-level trough will bring increasing southwesterly flow aloft on Wednesday, with a chance of showers, cooler temperatures, and onshore flow.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 MONDAY The upper low that brought clouds and light rain to the region Sunday moves northeast and is over Montana by Monday. A weak transitory ridge moves over western Oregon during the day. Weak onshore flow continues at low levels and will result in considerable cloudiness and cool temperatures. Cool surface temperatures mean lowered mixing heights and smoke dispersal conditions will only be fair most areas. OUTLOOK (TUESDAY-THURSDAY) A weak disturbance aloft increases onshore flow for continued cloudy conditions most zones on Tuesday. The Medford/Ashland area and the Siskiyous will be just partly cloudy. On Wednesday a broad upper trough approaches the Pacific Northwest turning upper flow southwesterly. A weak front will arrive late Wednesday but it doesn't appear that there is much moisture with this system. Clouds will hold temperatures down for coastal zones, but cooling aloft and better heating inland will push inland zone's mixing heights to about 5000 feet. On Thursday flow aloft is west-northwesterly with a similar temperature profile to Wednesday. Thus best smoke dispersal conditions will be away from the coast. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 TUESDAY A weak upper level ridge slowly moves east over the region during the day on Tuesday. Low level flow will be mostly onshore for clouds on the coast and just partly cloudy skies in the interior. Coastal temperatures will generally be 3-5 degrees below average while interior locations will see temperatures near to about 5 degrees above average. Cooler surface temperatures in the coastal zones will hold afternoon mixing heights down a bit while interior locations should see fair smoke dispersal conditions and areas east of I5 will see good conditions. OUTLOOK (WEDNESDAY-FRIDAY) The weak upper ridge moves east and is replaced by southwesterly flow aloft on Wednesday. Low level flow remains onshore. Coastal temperatures remain 3-5 degrees below average while interior locations will be near average. A disturbance in the SW flow aloft may produce afternoon thunderstorms over the Cascades. Mixing heights will rise high enough to give fair to good smoke dispersal conditions. Thursday will see a broad trough over the area but moisture will be limited. Expect mostly cloudy skies most areas. Smoke dispersal conditions will be fair along the coast and fair to good elsewhere. On Friday the broad tough moves to the east and a cool northwesterly flow aloft develops. Temperatures will generally be 5 to 8 degrees below average with smoke dispersal conditions similar to Thursday. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY An upper level trough deepens and moves toward the Pacific Northwest on Wednesday. The trough axis remains offshore for southwesterly flow aloft. Moisture will be limited but there is a possibility of showers or thunderstorms over the Cascades, especially during the afternoon. Cloudy conditions will keep temperatures on the coast about 4 to 6 degrees below average for the time of year. Interior temperatures will be near normal. The lack of daytime heating will keep mixing heights down, especially in coastal zones. Smoke dispersal conditions will be marginal to fair for portions of the south coast, otherwise fair to good conditions are likely. OUTLOOK (THURSDAY-SATURDAY) Thursday sees a westerly flow aloft with embedded disturbances moving with the flow. Again, very limited moisture so rain is not expected. Temperatures will remain slightly below average for the time of year, but mixing heights should push high enough for fair to good smoke dispersal conditions. A broad trough aloft sets up for Friday. Low level flow will be a little stronger onshore keeping temperatures 3 to 6 degrees below average. Mixing heights will struggle and smoke dispersal conditions will only be marginal to fair. Upper flow goes back to a generally westerly pattern with weak embedded disturbances but not much moisture. Temperatures will be 2-4 degrees below average in the north, near to a little above average in the southern interior. The cool temperatures will help to hold mixing heights down a bit for Saturday except in the southern Cascades. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Weak troughing will reside over the region tomorrow maintaining some marine clouds over the coastal regions, and inland over mainly the northern part of the state. Air mass will be somewhat stable during the morning, then destabilize during the afternoon. Expect mostly seasonal temperatures. Smoke dispersion will be fair to good. OUTLOOK (FRIDAY - SUNDAY) Upper level trough will remain over the region through Friday with a weak disturbance moving through the flow. Expect mainly just a thickening of the marine layer. Little to no moisture is likely. Upper level ridge will then move in Saturday and may give a brief period of offshore flow Saturday morning, mainly south. Ridge moves by to the east Sunday with a slow increase in onshore flow. Air mass will remain generally dry and stable over the weekend.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 FRIDAY A weak upper level trough will shift east of the Cascades by midday and progress to near the Idaho border by the evening. Strong low-level onshore flow will result in considerable morning low clouds west of the Cascade crest. Areas of morning drizzle are possible with skies slowly clearing in the afternoon. Light morning transport winds will turn northwesterly and increase in the afternoon with improving smoke dispersal conditions. Temperatures will cool to slightly below normal. OUTLOOK (SATURDAY-MONDAY) A flat upper-level ridge will move over Oregon Saturday with light morning transport winds. Morning marine clouds will break up more quickly with a sea-breeze increasing the onshore flow in the afternoon. Temperatures should warm to near or slightly above normal. The weakening ridge is forecast to get forced east of the state Sunday by a strengthening southwesterly flow aloft. That may trigger another inland surge of marine air late in the day. The marine layer is forecast to deepen on Monday with more extensive morning clouds and temperatures cooling back below normal. No significant precipitation is expected during the outlook period. Smoke dispersion should be fair to good in the afternoons. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SATURDAY A flat upper-level ridge will move over Oregon and may produce areas of offshore flow in the morning, mainly south. That could allow for late-morning burning, in southern coast range zones, before the sea-breeze turns the flow back onshore in the afternoon. Morning clouds will break up more quickly than on Friday with temperatures recovering to near normal north and slightly above normal south. Daytime smoke dispersal conditions should be fair in the western zones and fair to good in the eastern zones. OUTLOOK (SUNDAY-TUESDAY) The flat upper-level ridge is forecast to get forced east of the state Sunday by a strengthening southwesterly flow aloft. A weak surface thermal trough will also shift east of the Cascades by late in the day, which will increase the onshore flow across western Oregon. The marine layer is forecast to deepen Monday and Tuesday with more extensive morning clouds and possible areas of drizzle. No significant precipitation is expected during the outlook period, but there is a slight chance of showers on Tuesday, mainly over higher terrain. Temperatures will likely cool from just above normal Sunday to below normal by Tuesday. Mixing heights will be suppressed by the cool marine layer, especially in the mornings, but afternoon smoke dispersion should be fair to good during the outlook period. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SUNDAY A flat upper-level ridge is forecast to get forced east of the state by a strengthening southwesterly flow aloft. Weak onshore flow will bring only brief and patchy morning marine clouds inland with mostly sunny skies in the afternoon. Temperatures will be warmer than normal. Daytime smoke dispersal conditions should be fair to good. A surface thermal trough will begin the day near the Cascades and progress eastward, into eastern Oregon, by evening. That will induce increasing onshore flow, across all zones, in the afternoon and evening. The influx of cooler marine air will rapidly lower evening mixing heights. OUTLOOK (MONDAY-WEDNESDAY) As a fairly strong upper-level trough slowly approaches the coastline, increasing onshore flow will deepen the cool marine layer across western Oregon Monday and Tuesday. Morning low clouds will become more extensive, west of the Cascade crest, with areas of drizzle, mainly from the coast range westward. Temperatures will cool back below normal by Tuesday. The upper-level trough is forecast to come onshore Wednesday and will likely produce at least a few showers over mainly the northern zones. Temperatures will cool to as much as 10 degrees below normal with continued onshore flow. Morning mixing heights will be suppressed by the cool marine layer, but afternoon smoke dispersion should be fair to good during the outlook period. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 MONDAY An upper level low will drift to within about 300 miles west of the NW tip of Vancouver Island. Upper flow will be from the SW over Oregon. A very weak, but mostly dry, front will push into NW Oregon for more clouds than Sunday. Temperatures will be near to slightly below average except in the Rogue Valley where slightly above average temperatures are likely. Low level flow will be onshore, generally west or northwest, and cooler surface temperatures in the coastal zones will hold mixing heights down a bit. OUTLOOK (TUESDAY-THURSDAY) The upper low moves into southern British Columbia and the air mass continues to cool on Tuesday. Temperatures drop to generally 5 to 8 degrees below average. Cooler temperatures aloft will help maximum mixing heights to bump up from Monday. Low level flow remains onshore. Wednesday and Thursday will see the upper low pull out into central Canada, leaving a cool trough over the region. Temperatures will be around 5 to 10 degrees below average and low level flow will remain onshore. However, the cool air aloft should help maximum afternoon mixing heights to near 5000 feet most areas for good smoke dispersal conditions depending on wind direction. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 TUESDAY Upper air charts for Tuesday show a trough aloft with its axis extending from a low near the Queen Charlotte Islands southward to about 300 miles off the Oregon Coast. This gives southwesterly flow aloft over the region. Low level flow will be onshore, generally northwesterly for northern zones and more north-northwesterly for the south coast range. The southern Cascades will see more of a westerly transport. Skies will generally be cloudy early then inland areas will see partly cloudy to sunny skies in the afternoon. Temperatures will be 3 to 5 degrees below average on the coast and 5 to 10 degrees below average in the interior. In spite of cool surface temperatures the generally cool air mass over the region will produce a vertical temperature profile that gives high afternoon mixing heights for generally good smoke dispersal conditions depending only on low level/transport wind direction. OUTLOOK (WEDNESDAY-FRIDAY) Onshore flow and cooler than average temperatures will continue through the outlook period. A weak trough will remain over the area on Wednesday. Temperatures should be 3 to 8 degrees below average. Maximum mixing heights will push to above 4000 feet most areas for good smoke dispersal conditions. A progressive disturbance moving across the Pacific Ocean deepens the trough over the area and could produce some rain in the north on Thursday. Low level flow will be onshore with northerly surface winds most areas. The trough axis will pass to the east during the afternoon. Mixing heights should remain above 4000 feet most areas except the immediate coast. Temperatures will be 4 to 6 degrees below average for coastal areas and from 8 to 12 degrees below average in the interior. By Friday a cool west-northwesterly flow aloft will develop. Low level flow continues onshore, temperatures will run 4 to 8 degrees below average. Expect morning clouds with partial afternoon clearing most areas with maximum mixing heights well above 4000 through much of the region. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY Cool weather will continue. A broad upper trough remains over the eastern Pacific and the Pacific Northwest on Wednesday. Most areas will see clouds in the morning with the north becoming partly sunny in the afternoon and southern sections becoming mostly sunny. Low level flow will be onshore. Temperatures will be 3 to 7 degrees below average in the south and 7 to 10 degrees below average in the interior. Mixing heights should climb to above 4000 feet throughout the region for fair to good smoke dispersal conditions. OUTLOOK (THURSDAY-SATURDAY) A progressive disturbance moving across the Pacific Ocean deepens the trough over the area on Thursday. This supports a weak Pacific front that will move onshore late in the day. Winds turn southerly ahead of this front then westerly as it passes through. Best timing on frontal passage right now looks to be Thursday evening. This will bring some light rain, mainly to northern sections. Warm southerly flow aloft ahead of the weak front together with surface temperatures anywhere from 5 to 15 degrees below average will suppress mixing heights somewhat for only fair smoke dispersal conditions. The upper trough axis will pass to the east Friday morning leaving a cool west-northwesterly flow aloft. Low level flow will be back to northwesterly onshore, temperatures will run 5 to 10 degrees below average in the interior. There will be a slight chance of showers in northern sections. Saturday the low level onshore flow will continue with still a slight chance of a shower north, otherwise expect morning clouds with partial afternoon clearing most areas with maximum mixing heights around 4000 through much of the region. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 THURSDAY The persistent broad upper level trough that has been over the eastern Pacific and the Pacific Northwest will be reinforced by an upper short wave moving from the WNW across the Pacific Ocean. This supports a weak front that will move into NW Oregon during the day on Thursday. Timing of the front is problematical but it looks like we will have southerly or southwesterly winds ahead of the front. As it approaches winds will go more westerly then northwesterly with frontal passage. Temperatures will be cool with coastal regions seeing maximums 5 to 7 degrees below average and interior areas maxing out 6 to 12 degrees below average. Smoke dispersion conditions will be fair with maximum mixing heights between about 3000 and 4000 feet. OUTLOOK (FRIDAY-SUNDAY) Yet another upper short wave drops in to again reinforce the upper trough over the region early Friday. As this short wave moves to the east a cool northwesterly flow pattern aloft will set up. Temperatures will remain cool: 10-15 degrees below average for the time of year in the western valleys of Oregon. Expect some scattered showers in the north and fair to good smoke dispersal conditions. By Saturday some minor ridging is evident in the eastern Pacific and this ridge builds to more significant proportions by Sunday. This may eventually develop into a summertime ridge that finally brings significant warmth to the Pacific Northwest next week. In the meantime expect morning clouds with partial afternoon clearing in the north, afternoon sunshine in the south. The chance for some scattered showers continues in the north at least into Saturday. Smoke dispersal conditions Saturday and Sunday will be fair to good. 2.
