STRONG, GUSTY SOUTHWEST WINDS CONTINUE TO BE THE MAIN CONCERN,  
ESPECIALLY FOR PARTS OF SAN BERNARDINO COUNTY AND HIGHER ELEVATIONS  
OF THE SOUTHERN SIERRA AND WHITE MOUNTAINS. SUSTAINED SOUTHWEST  
WINDS OF 25-35 MPH WILL BE POSSIBLY IN THESE LOCATIONS WITH GUST  
POTENTIAL AS HIGH AS 50 MPH AT TIMES. MIN RH VALUES WILL FALL INTO  
THE LOW TEENS THIS AFTERNOON AS WELL, ESPECIALLY IN THE DESERT AREAS  
OF SAN BERNARDINO COUNTY AS WELL AS SOUTHERN MOHAVE COUNTY ARIZONA  
AND THE COLORADO RIVER VALLEY. THERE IS A POSSIBILITY FOR ISOLATED  
THUNDER CHANCES ACROSS ESMERALDA, NYE, AND LINCOLN COUNTIES THIS  
AFTERNOON WHICH MAY BRING VERY ISOLATED WETTING RAINS AS WELL.

THE RETURN OF THE MARINE LAYER WILL BRING COOLING TODAY FROM THE  
COAST INTO THE WESTERN VALLEYS WHILE AREAS FARTHER INLAND WARM  
SLIGHTLY. THE MARINE LAYER WILL DEEPEN FARTHER INTO THE VALLEYS  
TONIGHT AND ONTO THE COASTAL MOUNTAIN SLOPES ON SATURDAY NIGHT INTO  
SUNDAY MORNING. A LOW PRESSURE SYSTEM WILL MOVE ACROSS CALIFORNIA  
FOR LATE SATURDAY AND EARLY SUNDAY BRINGING SIGNIFICANT COOLING FOR  
THE WEEKEND. STRONGER ONSHORE FLOW WILL BRING GUSTY WEST WINDS TO  
THE MOUNTAINS AND DESERTS WITH STRONGEST WINDS FOR SATURDAY  
AFTERNOON AND NIGHT. THERE IS ALSO A SLIGHT CHANCE OF LIGHT SHOWERS  
FOR LATE SATURDAY NIGHT INTO EARLY SUNDAY MORNING, MAINLY ALONG AND  
WEST OF THE MOUNTAINS IN SAN DIEGO COUNTY. HIGH PRESSURE WILL  
STRENGTHEN ACROSS CALIFORNIA FOR MONDAY THROUGH WEDNESDAY OF NEXT  
WEEK BRINGING A STRONG WARMING TREND. THERE COULD BE A PERIOD OF  
OFFSHORE FLOW ON TUESDAY WITH STRONGER AND GUSTY NORTH WINDS IN THE  
SAN BERNARDINO COUNTY MOUNTAINS.  
 
   
..DISCUSSION FROM PHXFWFPSR
 
 
AN ELEVATED FIRE THREAT WILL EXIST SATURDAY ACROSS ALL DISTRICTS AS  
WIND GUSTS 20-25 MPH ACROSS SOUTHWEST AND SOUTH-CENTRAL ARIZONA, AND  
GUSTS UP TO 40 MPH IN PARTS OF SOUTHEAST CALIFORNIA, COMBINE WITH  
WARM TEMPERATURES AND HUMIDITY LEVELS FALLING INTO THE TEENS. FINE  
FUELS ARE BECOMING RECEPTIVE AFTER THE RECENT WARM, DRY WEATHER.  
ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS ARE POSSIBLE ON  
SATURDAY, WITH SOME ABATEMENT SUNDAY AS TEMPERATURES COOL AND  
HUMIDITIES RISE MODESTLY. HOWEVER, SOME BREEZY WINDS MAY PERSIST AND  
CREATE LOCALLY ELEVATED FIRE WEATHER CONDITIONS SUNDAY.
