..DISCUSSION FROM RNOFWFVEF
 
 
INCREASING WINDS WILL BE SEEN ACROSS THE REGION TODAY AHEAD OF A  
LOW PRESSURE SYSTEM WILL WILL MOVE INTO THE REGION. SOUTHWEST WINDS  
20-30 MPH WILL BE FAIRLY COMMON THIS AFTERNOON WITH SOME LOCATIONS  
APPROACHING 35 MPH. AT THIS TIME, IT LOOKS MARGINAL FOR ANY RED  
FLAG CONDITIONS. HOWEVER, THERE IS BETTER POTENTIAL OF SEEING  
MODERATE DOWNSLOPE WINDS LATE THIS AFTERNOON AND OVERNIGHT FOR THE  
EASTERN SIERRA SLOPES. WINDS COMBINED WITH POOR OVERNIGHT RH  
RECOVERIES SHOULD REACH CRITERIA AND HAVE GONE AHEAD AND ISSUED A  
RED FLAG WARNING FOR FIRE ZONE 226. WINDS AGAIN WILL BE MARGINAL FOR  
RED FLAG CONDITIONS ON THURSDAY AS A COLD FRONT MOVES THROUGH  
CENTRAL NEVADA. THERE COULD ALSO BE A FEW SHOWERS IMPACTING THE FAR  
NORTHERN ZONES ON THURSDAY, BUT WETTING RAINS ARE NOT EXPECTED.  
 
   
..DISCUSSION FROM LAXFWFSGX
 
 
GUSTY AND LOCALLY STRONG ONSHORE WINDS ARE EXPECTED EACH AFTERNOON  
AND EVENING THIS AFTERNOON THROUGH THURSDAY EVENING. TOP GUSTS  
SHOULD REACH 35 TO 45 MPH. THESE LOCAL WINDS WILL COMBINE WITH LOW  
INLAND HUMIDITY TO ELEVATE FIRE WEATHER CONDITIONS FOR FAVORED  
POCKETS ALONG MOUNTAIN RIDGES, THROUGH MOUNTAIN PASSES AND INTO  
ADJACENT DESERTS. WEAK OFFSHORE FLOW DEVELOPS EARLY FRIDAY, BUT ONLY  
SOME WEAK OFFSHORE BREEZES ARE EXPECTED IN THE FOOTHILLS. A SIMILAR  
OFFSHORE FLOW CONTINUES THROUGH THE WEEKEND. WARMER WEATHER IS  
EXPECTED THIS WEEKEND, BUT THE WINDS WILL BE LIGHT. A SWITCH TO  
ONSHORE FLOW MONDAY, WITH COOLER AND MORE HUMID WEATHER. A LOW  
PRESSURE SYSTEM BRINGS A SMALL CHANCE OF SHOWERS BY TUESDAY.  
 
   
..DISCUSSION FROM PHXFWFPSR
 
 
DRIER CONDITIONS WITH NEAR NORMAL TEMPERATURES ARE EXPECTED THROUGH  
WEDNESDAY. MINIMUM HUMIDITIES THIS AFTERNOON OF 10-25% WILL LOWER A  
BIT MORE INTO WEDNESDAY. WINDS TODAY WILL BE BREEZY AT TIMES DURING  
THE AFTERNOON, BUT OVERALL FAIRLY LIGHT WHILE WINDS WEDNESDAY WILL  
BE A BIT STRONGER WITH GUSTS TO AROUND 20 MPH. ANOTHER LOW PRESSURE  
SYSTEM WILL MOVE THROUGH THE GREAT BASIN ON THURSDAY BRINGING A  
SLIGHT CHANCE FOR WETTING RAINS ACROSS THE HIGHER TERRAIN EAST OF  
PHOENIX, SLIGHTLY COOLER TEMPS, AND WIDESPREAD BREEZY CONDITIONS  
WITH GUSTS UP TO 20-25 MPH.
