...SEASONABLY ELEVATED FIRE WEATHER CONDITIONS ACROSS INTERIOR SECTIONS
DUE TO GUSTY ONSHORE WINDS AND MODERATELY DRY CONDITIONS...
.DISCUSSION...
A deep marine layer will bring mild conditions and spots of drizzle from
the coasts to the foothills today with modest warming and decreased
marine layer influence to follow Friday through the weekend. Humidities
will generally stay above 25 percent, but very dry air above the marine
layer will keep minimum humidities of 10 to 20 percent going for some
mountain elevations above 5000 feet. Those humidities will lower into the
driest interior valleys and hills by Friday or Saturday. Winds will
generally be light, except for typically breezy southwest to northwest
winds over the interior areas of 15 to 25 mph with gusts of 25 to 35 mph,
as well as the Sundowner area of southwest Santa Barbara County.
