DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level ridge is passing by to the east this afternoon as increasing clouds from a frontal system and trough moving up from the southwest pushes in this evening. Scattered showers have already started in SW Oregon, but rain will increase this evening and spread northward. Expect continued showers tomorrow. Air mass will be somewhat stable during the night and early morning but cooler air moving in aloft, plus increasing southerly flow, will make for good mixing and dispersion on Saturday. OUTLOOK (SUNDAY - TUESDAY) Upper trough continues to move in Sunday with more moisture increasing during the late night to early morning hours Saturday/Sunday. Rain will continue on and off into Sunday before drying out some later in the day. Another front will move in later Monday bringing more rain and wind. Expect continued cool, breezy, and showery conditions into Tuesday. Air mass will be mostly unstable through the period, and with brisk SW'erly flow, smoke dispersion will remain mostly excellent. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper air charts show a deep, slow moving low in the southern Gulf of Alaska. A strong west-to-east jet to the south of that low will push moisture into the Pacific Northwest much of the week. A deep surface low develops off the southern Oregon coast and tracks northeastward toward Vancouver Island Monday afternoon and evening. This will eventually produce a strong south-to-north pressure gradient across western Oregon for strong southerly winds. Strongest winds will be at the coast and at ridge-top locations in the interior but even valley locations will see gusty winds beginning tomorrow afternoon. Good mixing for excellent smoke dispersal conditions and transport winds generally south to southeast. OUTLOOK (TUESDAY - THURSDAY): Showers continue on Tuesday then another Pacific Front increases rain Tuesday night. The Tuesday night system will not be as windy. Transport winds south-southwesterly. Post frontal showers continue Thursday with a south to southwest flow in low levels across western Oregon. By Thursday a moist onshore flow will keep shower chances in the forecast for the north but things may finally be drying out in the south. Even with some stabilization reducing the showers, mixing heights should remain high enough for good smoke dispersal conditions. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 The main jet stream and storm track remain aimed at the Pacific Northwest on Wednesday. A surge of moisture from the west-southwest will reach the coastline early and spread across the region for periods of rain throughout the day. Heaviest amounts will be during the morning hours. Transport winds will be generally southerly early then more southwesterly during the day. Mixing heights will remain high for favorable smoke dispersal conditions. OUTLOOK (THURSDAY-SATURDAY): Surface high pressure off the California coast builds northward slowly on Thursday. Expect showers during the day, most numerous in northern sections. Mixing heights remain high and winds Thursday will be westerly in the north and westerly turning to northwesterly in the south. By Friday the surface high noses into the Pacific Northwest for dry weather. A thermal trough develops in California and transport winds develop a northerly component. While weak ridging aloft develops Friday and Saturday there will still be a fairly strong west-to-east flow aloft with minor imbedded impulses. At this point it looks like dry weather for Saturday, however. Mixing heights Friday and Saturday will lower somewhat but still be high enough during the afternoons for fair to good smoke dispersal. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level trough in the eastern Pacific is ejecting a frontal system through the region today. Front will move east of the region tonight with moisture diminishing. Cooler air moving in aloft will lower the snow level down to 4000 - 5000 ft tomorrow. With the upper trough moving through tomorrow, expect a continued chance of showers. The threat of showers end by Thursday evening. Air mass will continue unstable and smoke dispersion good through tomorrow. OUTLOOK (FRIDAY - SUNDAY) Flat upper level ridge will dry out and stabilize the air mass early Friday. However, daytime heating should bring mixing levels up into the good category again. Generally the pattern will remain dry and tranquil through Sunday. A trough will approach Sunday and bring a marine push Sunday afternoon. Air mass will maintain a stable morning, unstable afternoon pattern through the period. Wind flow will remain mainly light, favoring northerly flow Friday and Saturday, then turn onshore on Sunday. Smoke dispersion will be mostly fair. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level ridge is building over the state today and will be at its peak Sunday morning. Then it gets shoved eastward by a trough and minor frontal system. This will set off a marine push over the region Sunday afternoon. Air mass will be stable during the morning then destabilize fairly well over the interior of the region under decent afternoon heating. Wind flow will be light and variable during the morning, and then increase from the S to SW during the afternoon. Smoke dispersion will be poor during the morning, and then improve during the afternoon. OUTLOOK (MONDAY - WEDNESDAY) Ridge gives way to an upper trough and front late Sunday into early Monday. Most of the moisture will be confined to the northern half of the state. The upper trough will move by to the east Tuesday with any residual showers decreasing. Temperatures will be cool with brisk westerly flow. Air mass will destabilize quickly Monday and remain unstable through Tuesday. Weak ridging moves in Wednesday but will be overridden by the next front during the afternoon. Expect more rain and wind. Expect mostly good to excellent smoke dispersion through the period. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 A Pacific weather system moves in from the west-southwest during the day Wednesday. Rain reaches the coast early afternoon and covers all of western Oregon by early evening. Mixing heights remain high for good smoke dispersal conditions. Transport in winds in the north start out southeast then become more southerly as the front approaches and its parent low tracks into western Washington. OUTLOOK (THURSDAY-SATURDAY): High pressure aloft builds on Thursday. Showers are sill possible early in the day but should end as the air mass stabilizes. Mixing heights should remain favorable for good smoke dispersal however and transport winds will be generally southwesterly. Expect continued high pressure aloft on Friday and Saturday for dry weather. Nighttime inversions will trap residual smoke near the ground but daytime heating should push mixing heights to the 3500 to 4500 foot range for fair to good smoke dispersal conditions. Transport winds late in the week will be generally northwesterly to northerly. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 2100 - 3100 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level ridge will remain strong over the region through tomorrow providing probably the warmest temperatures of the year. Air mass will remain stable with a brief period of good mixing in the interior during maximum afternoon heating. Wind flow will remain light northerly leading to most poor to fair smoke dispersion. OUTLOOK (MONDAY - WEDNESDAY) Upper ridge will shift to the east on Monday as an upper trough and minor front approach. Marine push will move inland during the afternoon, cooling down the very warm temperatures and shifting smoke inland for any Coast Range burning. Trough and front move in Tuesday providing a little moisture over the coast and northern interior. Air mass destabilizes and dispersion improves under decent onshore flow. Trough moves to the east Wednesday with a flat ridge replacing it. Wind flow turns northerly again. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 1000 - 2000 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 The upper ridge that provided several days of sunny and warm weather to the Pacific Northwest will have moved to the northern plains states by Tuesday and an upper level low will be moving into British Columbia. A broad upper level trough will cover Oregon and Washington. An associated, relatively weak, cold front will move into western Oregon overnight Monday night and early Tuesday. Rainfall amounts could amount to about three-tenths of an inch in the north and about a tenth of an inch in the south. Rain will change to showers during the afternoon. Transport winds will be generally west to northwest and mixing heights high enough to provide for good smoke dispersal conditions in the afternoon. OUTLOOK (WEDNESDAY - FRIDAY): Temporary weak ridging will return to the region Wednesday to begin a period of generally dry weather. Afternoon mountain showers are a possibility. Mixing heights will lower somewhat but smoke dispersal conditions will remain good in the Cascades and fair in the coast range and SW Oregon. By Thursday a thermal trough will develop and move into southwestern Oregon. This will give northerly transport winds early. As the trough shifts during the day winds will go onshore and become more northwesterly. Friday the onshore gradients will continue with only marginal to fair smoke dispersal conditions west of I-5 but continued good conditions in the Cascades. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 The upper level trough that brought rain to many parts of Oregon shifts to the east on Wednesday. Weak ridging aloft moves in to cut off any remaining showers overnight and give dry weather during the day. Mixing heights in coastal zones and the interior valleys will allow fair smoke dispersal conditions with good conditions likely in the Cascades. Transport winds will be generally northerly or slightly northwesterly. OUTLOOK (THURSDAY-SATURDAY): Weak ridging aloft continues Thursday for dry weather. Temperatures climb to above normal levels. Most zones will see marginal to fair smoke dispersal conditions while conditions in the Cascades will be good. Transport winds remain north to northwest. Friday and Saturday a generally west-to-east flow in the upper atmosphere will prevail, but with minor impulses rippling past in the flow. These could touch off afternoon or evening thunderstorms mainly over mountainous regions. Smoke dispersal conditions will be marginal to fair along the coast and the interior valleys, but good in the Cascades. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Fairly non-descript pattern aloft. Weak upper level ridge is over the northern Rockies, while the upstream trough is well to the west. This leaves generally westerly flow aloft. A minor short-wave trough slides toward the area Friday but will have little impact beyond an increase in morning low clouds in the west. Otherwise, pleasant day with generally northerly low level flow. Will need to watch for increased onshore flow along the coast as the short-wave approaches. In the interior, daytime mixing will be good but the onshore flow of cooler marine air will tend to limit mixing west of the Coast Range crest. OUTLOOK (SATURDAY - MONDAY) Tendency over the next few days will be for gradual strengthening of the ridge aloft and, consequently, a gradual lowering of the daytime mixing height over most of the area. Daytime heating will be sufficient in the southern interior to keep daytime mixing height up. However, overnight mixing becomes very poor throughout western Oregon. Any unit that would smolder into the night should be avoided near SSRAs or drainages into those areas. Low level wind flow continues generally northerly through the period. Direction tends slightly offshore during the nights and early mornings and more onshore during the afternoon. Overall trend will be toward gradually worsening dispersion as the Memorial Day weekend approaches. 2. DISPERSION Zone 601-603, 612 and 615-620 (North and South Coast Range): MORNING Mixing height 2800 - 3800 ft. Transport wind NW to N at 8 - 14 mph. Surface wind NW to N at 8 - 12 mph.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Weak ridging aloft over the Pacific Northwest with a minor short-wave trough passing through the northern part of the state. Morning low clouds will be a little more extensive Saturday. By afternoon, mostly sunny except along the immediate coast. Onshore flow of low-level, cool air caps the mixing height in the coastal zones. In the interior, stability is just enough to limit mixing somewhat. Generally northerly low-level transport with a tendency to onshore. Overall dispersion tends to be limited, especially in the Coast Range. Suggest burning be curtailed for the Memorial Day Holiday weekend. OUTLOOK (SUNDAY - TUESDAY) As the short-wave moves east, the air mass continues to gradually stabilize, further limiting dispersion. Enough heating for fair daytime mixing but as the sun sets, mixing height drops to less than 1000 ft. Low level wind flow changes little; generally northerly with a tendency to onshore flow during the days. As mentioned above, with the holiday and limited dispersion, recommend against burning that could impact recreational areas as well as SSRAs. 2.

A forecaster will be available Monday to prepare an instruction for Tuesday and to assist in planning for Tuesday's burning. Recommend against burning on Sunday and Monday. 1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 West to southwest flow aloft over the Pacific Northwest brings warm dry weather to western Oregon. In the low levels light onshore flow continues to bring morning clouds to the west side of the Coast Range. Some of these clouds seep through the corridors into the interior valleys. Cool air near the surface with warmer, subsiding air aloft keeps mixing limited, especially over the coastal zones. Light northerly transport continues. Tendency in the lowest levels to onshore transport. Poor night and morning dispersion but heating brings generally fair dispersion along the coast and good dispersion in the interior during the day. OUTLOOK (MONDAY - WEDNESDAY) Not a lot of change through mid-week. If anything, the upper level pattern tends to a stronger ridge and more limited mixing. This could set up increased offshore transport in the mornings but heating pulls the low-level flow onshore in the afternoons. Dispersion limited as a result, so burning will remain somewhat restricted. 2. DISPERSION Zone 601-603, 612 and 615-620 (North and South Coast Range): MORNING Mixing height 2400 - 3400 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 The jet stream shifts northward on Wednesday as high pressure builds aloft. Dry weather will prevail across the entire Pacific Northwest. Temperatures should be up about five degrees from Tuesday. Mixing heights at the coast will be somewhat limited but during the afternoon should provide for fair smoke dispersal. Cascades will see good to excellent smoke dispersal conditions. OUTLOOK (THURSDAY-SATURDAY) The upper level high pressure area continues to build. The high center will be over the Great Basin and clockwise flow around the high could bring some moisture north for the possibility of afternoon or early evening thunderstorms Thursday and Friday, mainly over the southern Cascades. Mixing heights will remain favorable for good smoke dispersal conditions. A weather system moving across British Columbia flattens the ridge Friday and turns upper flow more southwesterly with lessons the chance for thunderstorms. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 A strong upper ridge sets up over the Great Basin on Thursday. Clockwise flow around the low gives Oregon a south to southwest flow aloft. This could bring up some high level moisture from the south for a chance of afternoon or evening mountain thunderstorms. Low level flow will be onshore or northerly. Mixing heights along the coast give marginal smoke dispersal conditions for coastal zones but conditions should be good elsewhere. OUTLOOK (FRIDAY-SUNDAY) Temperatures will remain above average across the state through the outlook period. The upper ridge strengthens Friday. The chance for afternoon or evening mountain thunderstorms continues. Mixing heights should be near 5000 feet or above except for coastal areas. Expect shifting transport winds Friday. The upper ridge gets flattened by a weather system moving across northern British Columbia. The onshore flow strengthens a bit Saturday for slightly cooler temperatures west of the Cascades. Transport winds remain generally north or northwesterly over the weekend. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 1000 - 1700 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level ridge will remain in place through Saturday with the axis of the ridge near the Oregon/Idaho border. Expect continued summer-like weather. Air mass will remain stable except for brief afternoon instability inland due to daytime heating. Some thunderstorm buildups will continue in the afternoon to evening over the Cascades - mainly the southern half. Wind flow will remain weak and favor generally a NW to NE flow.

OUTLOOK (SUNDAY - TUESDAY) Upper level ridge starts weakening on Sunday as a trough moves down from the north and an upper low approaches from the southwest. However, expect continued warm and dry conditions. Thundershower threat will get pushed mainly southward. Eventually the upper level low in the eastern Pacific and to the southwest of the state will move close enough to bring increased clouds and maybe some moisture over the region on Tuesday. Air mass will destabilize more then. Wind flow will remain light and mostly northerly Sunday and Monday. As the low approaches Tuesday, wind flow appears it will turn lightly offshore.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 Upper level ridge will weaken over the next couple of days as an upper low approaches from the southwest and a trough drops down from the north. Southerly flow aloft will continue the thundershower threat over the Siskiyous, Cascades and to the east. Air mass will remain stable and smoke dispersion mainly poor due to little wind movement. Wind flow has turned lightly onshore and this will reduce temperatures a few degrees. Otherwise expect mostly fair skies. OUTLOOK (MONDAY - WEDNESDAY) Upper level trough moves in closer on Monday and increases the chance of showers or thundershowers over the west side of the Cascades. This threat will continue and move further north on Tuesday. Air mass cools and destabilizes. As the low approaches wind flow becomes more erratic and starts turning offshore. Upper low will continue spinning around to the south into Wednesday. However, it appears it will have less of an influence on our weather with showers decreasing. Air mass will stabilize some. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 An upper level ridge centered over the northern Great Basin will keep conditions warm into the first part of next week. Southerly flow will continue to produce enough moisture for the threat of afternoon and evening thunderstorms mainly over the Cascades. Nighttime inversions will hold smoke close to the ground overnight and into the morning hours. During the afternoon mixing heights will improve smoke dispersal conditions to poor in the north Coast Range, and fair in the South Coast range. Smoke dispersal conditions reach moderate during the afternoon in the Cascades. OUTLOOK (TUESDAY - THURSDAY) The upper level ridge slips slowly eastward and an upper level low moves slightly closer to the California coastline on Monday. Counter-clockwise flow around that low could bring some of the Cascade thunderstorms west into the Willamette Valley or the Coast Range. The upper low remains off the California coast through the outlook period. Afternoon instability will help smoke dispersion, but the window for acceptable smoke dispersal conditions remains narrow with unfavorable conditions evenings and mornings. 2.
