DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623 The cool upper level low that has been over the region for the past couple of days will finally drop south into Nevada overnight Tuesday night leaving the Pacific Northwest in a northerly flow aloft early in the day. A few showers are still possible early, mainly over the Cascades. A weak upper ridge will build during the day ending any showers. Transport winds should be generally northwest across western Oregon, backing to westerly in northern zones in the afternoon. Mixing heights should allow fair to good smoke dispersal conditions. OUTLOOK (THURSDAY - SATURDAY) On Thursday flat ridging should keep the area dry. Expect southerly winds most of western Oregon, but more of a westerly or northwesterly wind in the Rogue Valley. Computer models are not as strong on the ridge as they were yesterday and thus it now looks like mixing heights will remain higher than previously thought. Expect fair to good smoke dispersal Thursday. Models are now showing a weak Pacific cold front for Thursday night and Friday with dry weather returning for the weekend. 2.

DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625 Upper trough drifting to the south of the area this afternoon and evening will likely be too weak to bring more than the slightest chance of a few showers. Clouds decrease overnight and Friday will be mostly sunny and mild. A ridge is building over the eastern Pacific but it remain far enough west to little impact on mixing. Mixing height rises to 5000 ft or more during the afternoon. Transport flow generally northerly with a slight tendency to northeast. Smoke dispersion should be good through the day, worsening overnight as a nighttime inversion develops. OUTLOOK (SATURDAY - MONDAY): Upper level ridge stationary to the west with northerly flow keeping temperatures fairly cool.
