AND DEATH VALLEY. ELEVATED WINDS PERSIST INTO WEDNESDAY IN THE
WESTERN MOJAVE DESERT AS WELL. LIGHT PRECIPITATION IS POSSIBLE IN
THE SIERRA AND SOUTHERN GREAT BASIN, BUT MOST OF THE AREA WILL

TEMPERATURES DROP AROUND 10 DEGREES TODAY AND TOMORROW WITH THE
PASSAGE OF A COLD FRONT. NEAR NORMAL TEMPERATURES, LIGHTER WINDS,
AND DRY CONDITIONS CAN BE EXPECTED ON THURSDAY AND FRIDAY.
..DISCUSSION FROM LAXFWFSGX
COOLER THROUGH WEDNESDAY WITH STRONG GUSTY SOUTHWEST TO WEST
WINDS FOR THE MOUNTAINS AND DESERTS GUSTING TO 40 TO 50 MPH FOR
THIS AFTERNOON AND NIGHT WITH ISOLATED GUSTS TO 65 MPH. THERE IS A
CHANCE OF LIGHT SHOWERS FOR LATE THIS AFTERNOON THROUGH THIS
EVENING FROM A WEAKENING COLD FRONT. THE CHANCE FOR WETTING
PRECIPITATION FOR THE SAN BERNARDINO COUNTY MOUNTAINS IS 10 TO 20
PERCENT, AND LESS THAN 10 PERCENT ELSEWHERE. IT WILL BE DRY WITH
SEASONAL TEMPERATURES FOR THURSDAY AND FRIDAY, THEN COOLER AND
BREEZY FOR THE WEEKEND WITH A CHANCE OF SHOWERS FROM THE COAST TO
THE MOUNTAINS.
..DISCUSSION FROM PHXFWFPSR
ABOVE NORMAL TEMPERATURES WITH BREEZY TO WINDY CONDITIONS ARE
EXPECTED TODAY, ESPECIALLY ACROSS THE WESTERN DISTRICTS AS A
WEATHER SYSTEM APPROACHES THE REGION. WINDS WILL BE STRONGEST IN SE
CALIFORNIA WHERE GUSTS TO 25-35 MPH CAN BE EXPECTED. THESE STRONGER
WINDS COUPLED WITH VERY DRY CONDITIONS (RH AS LOW AS 10%) WILL
RESULT IN A BRIEF PERIOD OF NEAR CRITICAL FIRE WEATHER CONDITIONS
THIS AFTERNOON. ELSEWHERE, BREEZY CONDITIONS WITH GUSTS AROUND
20-25 MPH CAN BE ANTICIPATED. ELEVATED FIRE WEATHER CONDITIONS WILL
SHIFT TO THE EASTERN DISTRICTS ON WEDNESDAY. MINRH WILL CONTINUE TO
BOTTOM OUT AROUND 8-15% WITH OVERNIGHT RECOVERIES RANGING FROM POOR
TO FAIR OR GENERALLY BETWEEN 30-50% OVER THE NEXT COUPLE NIGHTS.
