Day 1 Fire Weather Outlook
SOUTHEASTERN VENTURA COUNTY… A mid-level low over the central Plains will weaken and transition to an open wave, quickly becoming absorbed within defined troughing over the Upper Midwest. Meanwhile, a cutoff low will detach into the Desert Southwest as surface high pressure migrates into the Intermountain West and central CONUS. As a result, an increasing offshore pressure gradient will promote a fire weather threat for portions of southern CA that have not seen recent rainfall. The fire weather threat will increase markedly early this morning into the early afternoon hours as offshore flow accelerates across portions of southern CA. Resultant east-northeast winds of 15-25 mph will emerge with related downslope drying from a dry airmass originating from the Colorado Plateau, allowing for RH reductions as low as 10%. A corridor of stronger east-northeast winds of 20-30 mph with gusts of
COUNTY…SOUTHEASTERN SANTA BARBARA COUNTY… An amplified upper trough will progress over the eastern CONUS as a surface low departs from New England. A substantial cold front will sweep across the southeastern CONUS on Day 2/Friday, with dry post-frontal flow bringing fire weather concerns to portions of the lower MS River Valley. High pressure building in behind the cold front along with a mid-level cutoff low over the Baja Peninsula will continue to support offshore flow and a fire weather threat across portions of CA. An offshore wind event will continue through Day 2/Friday across much of southern CA, maintaining an Elevated fire weather threat. A mid/upper cut-off low over the Baja Peninsula will aid in deep layer easterly flow over the region, supporting surface winds of 20-30 mph (gusts up to 40 mph in the valleys, possibly up to 60 mph in the mountains) amid 10-15% RH.
