DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 TUESDAY Upper level flow will be generally west-southwest ahead of a weak trough about 400 miles west of the southern Oregon Coast. That trough will approach during the day, but it is weak and mainly headed toward California, so its primary effect will be a few mid and high clouds over the region. No rain is likely. OUTLOOK (WEDNESDAY-FRIDAY) The trough moves into California on Wednesday leaving a weak ridge over the area for dry weather. By Thursday a weakening front drags across northwestern Oregon for some light rain in north Coast Range and the northern Cascades. By Friday a deep upper low is about 600 miles west of Vancouver Island. This helps to build a ridge over the region for dry weather and warmer temperatures but also lower mixing heights. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY An upper level trough moves from California to Nevada during the day. A weak upper ridge builds into western Oregon behind the trough. Surface high pressure builds northward also. Weather will be dry, and maximum mixing heights generally between 4000 and 5000 feet. OUTLOOK (THURSDAY-SATURDAY) On Thursday a weakening upper disturbance moves into British Columbia and a weak trailing cold front drags across northwest Oregon. Some light rain is likely in the extreme northwestern corner of the state, otherwise expect dry weather and fair to good smoke dispersal conditions. By Friday a deep upper low in the Gulf of Alaska builds a moderate upper ridge over the Pacific Northwest. This will give dry weather but warm air aloft will suppress mixing heights a bit. The upper low moves closer on Saturday and flow aloft veers to more southerly. However, moisture stays well east of the state for more pleasant, dry weather. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 THURSDAY A weak upper disturbance moves into British Columbia during the day. This will support a weak Pacific cold front dragging into northwest Oregon during the day. This should produce some light rain in the northern coastal zones otherwise look for dry weather. Mixing heights will be high enough to allow for fair smoke dispersal conditions most areas. Winds should be generally southwesterly in the north and light westerly in the south. OUTLOOK (FRIDAY-SUNDAY) An upper level low settles into the Gulf of Alaska about 600 miles west of the Queen Charlotte Islands on Friday. Southwesterly flow aloft ahead of this system will bring in warmer air at higher altitudes and suppress mixing heights for a couple of days. Winds will be generally light and variable. Saturday will see the flow aloft back to more southerly and mixing heights will be suppressed and smoke dispersal conditions will only be marginal. Sunday the flow veers to more southwesterly again and mixing heights improve somewhat. 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 FRIDAY A building ridge of high pressure will begin clearing skies over western Oregon with temperatures returning to normal. However, light transport winds will make for only marginal ventilation conditions. OUTLOOK (SATURDAY-MONDAY) A very weak weather system is forecast to bring some clouds late Saturday and Sunday. Although most of the precipitation should stay north of Oregon, some light rain is likely along the northern and central coast and over the north coastal range. Light rain could penetrate inland as far as the northern Cascades, but southern zones appear as if they will stay dry. The weak frontal system will cause some increase in transport winds, which will bring some improvement to the ventilation conditions. The upper-level ridge is forecast to rebound Monday with dry weather and slackening transport winds. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 SATURDAY Southwesterly flow aloft will begin to increase Saturday, as a broad upper-level ridge shifts east of Oregon. Mostly sunny skies will give way to increasing high clouds late, especially over western zones. Increasing transport wind speeds will improve ventilation conditions. OUTLOOK (SUNDAY-TUESDAY) A weak weather system is forecast to bring light rain onshore Sunday morning, mainly north. Some rain could spread as far south and east as the central Cascades by Sunday afternoon. Southwestern zones will see some increase in clouds but should stay dry, except for near the coastline. The upper-level ridge is forecast to rebuild over the region Monday, which will create strong morning inversions with patchy valley fog. Afternoon sunshine will provide good mixing, but transport winds will be light. Increasing southwesterly flow aloft is forecast to bring another weak system into western Washington and northwestern Oregon Tuesday. Increasing transport winds should improve ventilation conditions with only minimal precipitation, mainly north. 2.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 High pressure remains over the region for fair skies and warm temperatures and relatively light winds aloft. The high is centered to the south of the Pacific Northwest and to the west, over the ocean, flow is southwesterly. Warm air aloft will suppress mixing heights for marginal to fair smoke dispersal conditions. EXTENDED OUTLOOK (WEDNESDAY - THURSDAY) The ridge aloft builds Wednesday and mixing heights continue to decrease. Smoke dispersal conditions will only be marginal along the coast and in the north interior. On Thursday a disturbance embedded in the southwesterly flow aloft offshore turns higher level winds more southwesterly but mixing heights continue to decrease with many areas seeing maximum mixing heights of only about 2000 feet above ground level. By Friday the disturbance is in Canada, mixing heights remain low, and low level flow goes onshore. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height 1200 - 2200 ft.

DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 WEDNESDAY In the upper atmosphere a ridge covers the Pacific Northwest for Wednesday. The ridge is centered to the south with a generally west to east flow aloft over the region. Warm air aloft with this ridge will produce very stable conditions and mixing heights will be quite low. South Coast Range zones and the north Cascades will have only marginal smoke dispersal conditions. Winds will be generally NNE to E across the area. EXTENDED OUTLOOK (THURSDAY - SATURDAY) An upper level disturbance moves SW to NE offshore toward southwestern British Columbia on Thursday. A surface thermal trough will extend from central California into SW Oregon. Low mixing heights will continue and winds will be generally NE for northern zones and SE for southern zones. On Friday the upper ridge retreats slightly eastward and the thermal trough shifts eastward as well. This should allow onshore flow in low levels. Mixing heights remain suppressed. Winds will be generally southwesterly except light and variable in the south. The upper ridge flattens Saturday but mixing heights remain suppressed with potentially poor smoke dispersal conditions for the north Coast Range and marginal conditions in the north Cascades. The south Coast Range and the southern Cascades will see some improvement. 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 THURSDAY A strong upper-level ridge will remain over the Pacific Northwest but shift slightly eastward. The ridge axis will extend from eastern Nevada northwestward, over eastern Oregon, into British Columbia. A surface thermal trough will shift inland, into southern Oregon, and extend northwestward to just off the north coast. Suppressed mixing heights and light transport winds will make for marginal ventilation conditions. OUTLOOK (FRIDAY-SUNDAY) The upper-level ridge will weaken and continue to slowly shift eastward. The surface thermal trough is forecast to progress east of the Cascades Friday with light onshore transport winds. Transport winds are expected to turn more northerly Saturday, and then turn strongly onshore Sunday, as an upper-level trough, and corresponding cold front, approach the coastline. That will improve ventilation conditions. 2. DISPERSION Zone 601, 602, 603 and 612 (North Coast Range): MORNING Mixing height below 500 ft early rising to 1000 - 1900 ft by late morning.
