DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 An upper level ridge axis will remain about 600 miles west of the coastline. Clockwise flow around that ridge leaves the Pacific Northwest in a generally north or northwesterly flow pattern aloft. Surface temperatures at the surface will be warm enough and temperatures aloft will be cool enough to provide high mixing heights and good smoke dispersal conditions. OUTLOOK (THURSDAY-SATURDAY) The pattern changes little for Thursday with northwesterly flow aloft over the region for dry weather. By Friday the ridge axis moves a little closer and sharpens although it is still some 500 miles west of the coastline. A pattern change begins on Saturday as the ridge weakens and splits. This will eventually allow a Pacific system to undercut the ridge and bring rain to the region the first part of next week. 2. DISPERSION WEDNESDAY Mixing height 2700 - 3700 ft during the morning.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 A complex upper air situation in progress during the day on Tuesday. An upper level low will retrograde westward across central British Columbia and a second upper level low will move toward Oregon over the ocean from the southwest. The two systems will combine for southwesterly flow aloft and a Pacific cold front will spread rain into the region. Amounts will be significant, greatest since last spring most areas, however the heaviest rains will actually move into northern California. OUTLOOK (WEDNESDAY-FRIDAY) Expect post-frontal showers on Wednesday. Snow levels should be 7000 feet or above. Mixing heights should be quite high for good smoke dispersal conditions. On Thursday a front moves mainly into northwest Oregon and western Washington. Some scattered showers may continue in the area. By Friday dry weather will return to the area.

Next frontal system will override the ridge later Sunday as a warm front spreads clouds over the area during the day with light rain beginning during the evening and overnight. Increasing wind flow from the southwest will slowly improve smoke dispersion. OUTLOOK (MONDAY - WEDNESDAY): Ridge slides to the east early Monday giving way to the cold front and upper level trough. Expect a fairly decent amount of moisture over the region. Cooler air will move in aloft to destabilize the air mass and lower snow levels. Upper trough moves by to the east Tuesday but with a strong northwesterly jet stream over the region, cool showers will continue with the snow level lowering to the valley floors. Air mass will be quite unstable. The next upper level ridge starts building in Wednesday but with chilly air remaining over the region, the air mass will remain mostly unstable.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 The wet Pacific cold front that brought a little rain to the region Monday will be well to the east and dissipating. The cool upper trough supporting that system will move to the northern Rockies leaving a cool northerly flow aloft over Oregon. This will keep the atmosphere destabilized with mixing heights above 5000 feet most areas. Winds will remain brisk for favorable smoke dispersal conditions most areas. Expect scattered showers during the day, gradually dissipating by late afternoon. OUTLOOK (WEDNESDAY-FRIDAY) An upper level ridge builds in the eastern Pacific and moves over the region on Wednesday. Weather will be dry, however the ridge will progress to the east and allow another Pacific warm front to approach the coast Wednesday evening. This may produce some light rain in the region by Thursday. Friday will see showers with another Pacific front due in on Saturday.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 Upper level ridge continues to build over the state but is being overrun by clouds from a warm front off the coast. This front will continue to pump clouds into the region through Thursday as it slowly moves in. Little, if any, rain is likely. Air mass will remain stable as warming air aloft continues to enhance the lower level temperature inversion. Increasing wind flow from the south should provide fair smoke dispersion. OUTLOOK (FRIDAY - SUNDAY): Upper ridge with warm front clouds continues through Friday before the ridge flattens and gives way to a cold front on Saturday. Moisture amounts from the cold front will be light. Air mass will destabilize Saturday for a brief period before stabilizing again Saturday night and Sunday as the upper ridge rebuilds again. Wind flow will increase as the front moves through on Saturday, providing decent smoke dispersion. Winds then decrease later Saturday and become quite light on Sunday, making for considerably poorer smoke dispersion. 2.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 Upper level ridge will remain over the region tonight and Friday before flattening and giving way to a cold front late Friday and early Saturday. Currently the warm front is arcing over the ridge and spreading mainly clouds over the region today. This will diminish tomorrow as the warm frontal zone moves off to the east. Air mass mixes out with the warm air aloft mixing down to the surface and improving mixing conditions. Light to moderate winds will keep smoke dispersion mostly fair. OUTLOOK (SATURDAY - MONDAY): Cold front moves into the region on Saturday, gradually breaking apart as it moves through. Moisture amounts will be quite light. Upper ridge will then rebuild Sunday, stabilizing the air mass later in the day. Ridge remains overhead but moves somewhat eastward on Monday. Smoke dispersion will gradually worsen through the period. 2. DISPERSION FRIDAY Mixing height 2200 - 3200 ft during the morning. Afternoon mixing height rises to 3500 - 4500 ft then lowers to 2500 - 3500 ft during the evening. Transport wind SSW to W at 6 - 12 mph during the morning. Transport wind increases to SW to W at 10 - 16 mph during the afternoon and evening. Surface wind SSW to WSW at 4 - 8 mph. OUTLOOK: SATURDAY Mixing height 2700 - 3700 ft during the morning rising above 5000 ft during the afternoon. Transport wind SW to WSW at 14 - 28 mph.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 Upper level ridge will move off to the east tonight giving way to a cold front that will move through the region on Saturday. The front will provide a chance of some light rain, but overall, moisture amounts will be quite limited. Cooler air follows the front but since the trough is not too deep, snow levels will not get as low as earlier in the week. Air mass briefly destabilizes tomorrow afternoon as the trough passes, providing decent smoke dispersion. OUTLOOK (SUNDAY - TUESDAY): Upper level ridge rebuilds rather quickly on Sunday with the air mass stabilizing through the day. Upper ridge will remain over the state for the rest of the period further stabilizing the air mass. Expect mostly sunny skies. 2.
