INCREASE WEDNESDAY AFTERNOON, WITH THE BEST SIGNAL FOR GUSTS
GREATER THAN 35 MPH FOCUSED ALONG THE SIERRA FRONT, NORTHEAST CA,
WESTERN NV, AND PORTIONS OF WEST-CENTRAL NV. THIS MAY PRODUCE
AREAS OF ELEVATED FIRE WEATHER CONCERNS WHERE FUELS ARE RECEPTIVE.

COOLING TREND. WINDS MAY BEGIN TO INCREASE FRIDAY, WITH THE
STRONGER WIND PERIOD STILL FAVORED SATURDAY. FIRE WEATHER CONCERNS
MAY INCREASE AGAIN WHERE FUELS REMAIN RECEPTIVE, BUT THE MAGNITUDE
AND COVERAGE WILL DEPEND ON THE EVENTUAL TROUGH TRACK, WIND
STRENGTH, AND AFTERNOON RH. SHOWER CHANCES REMAIN LOW, GENERALLY
10% OR LESS, ALTHOUGH A SLIGHTLY WETTER TREND REMAINS POSSIBLE BY
