Smoke Call Status:

Weekdays (M-F) @ 1300 hrs PDT

Issued:

12:30 PM Monday, October 03, 2022

Discussion:

Upper level ridging will persist overhead Tue & Wed with smoke dispersion conditions remaining somewhat limited by the stabilizing influence of the ridge and rather light wind pattern. Aside from localized sea breeze and terrain driven winds, both surface and transport winds will remain minimal Tue & Wed significantly limiting ventilation. Above normal temps will support moderately deep mixing heights over inland areas for a few hours each afternoon with moderate to strong valley inversions forming each night.

Extended Outlook:

Thursday - Saturday

Little change in the weather pattern is expected through the end of the week with upper level ridging persisting overhead through Fri and the general wind pattern remaining light. Continued above normal temperatures will support fairly good vertical mixing in the afternoons, but overall smoke dispersion conditions will remain limited due to the lack of any organized transport winds to carry smoke away and stronger than normal overnight inversions.
