Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0204 AM CST Thu Feb 27 2020

Valid 271200Z - 281200Z

Fire-weather concerns during the D1/Thu forecast period will remain
focused across the southern California coastal ranges as a favorable
synoptic pattern for offshore flow continues across the West.  The
offshore flow pattern should weaken some, however, mainly due to
weakening Great Basin high pressure.  Elsewhere, fire-weather
concerns are expected to remain low.

...Southern California...
Despite a gradually weakening surface pressure gradient during the
day, models continue to indicate areas of 25-35 mph easterly surface
winds (with locally higher gusts near terrain-favored areas)
persisting through the afternoon and evening.  A pre-existing dry
airmass will remain in place, and insolation/warming will readily
lower RH values into single-digits and low teens during peak heating
hours.  These atmospheric conditions ordinarily support at least an
elevated delineation with expectation of locally critical fire
weather, though fuels remain a limiting factor for a higher threat.
