HIGH CONFIDENCE THAT CRITICAL FIRE WEATHER CONDITIONS WILL BE SEEN  
ACROSS MUCH OF THE SOUTHERN GREAT BASIN AND MOJAVE DESERT TUESDAY  
AFTERNOON AND EVENING. LESS CONFIDENT THAT WIDESPREAD CONDITIONS  
WILL BE SEEN ON WEDNESDAY. AREA FUEL DRYNESS IS APPROACHING, IF NOT  
ALREADY CRITICAL WITH LITTLE TO NO POTENTIAL FOR SIGNIFICANT  
WETTING RAINS IN THE FORECAST THROUGH THE WEEK.  
 
   
..DISCUSSION FROM LAXFWFSGX
 
 
FAIR AND MILD SPRING WEATHER WILL PREVAIL THROUGH MONDAY, WITH  
PERIODS OF NIGHT AND MORNING LOW CLOUDS AND FOG ALONG THE COAST, AND  
INTO THE VALLEYS, AND WEAK TO MODERATE ONSHORE FLOW. A COLD, SPRING  
STORM SYSTEM DEVELOPING OVER THE NORTHERN GREAT BASIN WILL BRING  
STRONGER AND GUSTY WESTERLY WINDS, COOLING, AND A DEEPER MARINE  
LAYER WITH HIGHER RELATIVE HUMIDITY INLAND LATE MONDAY THROUGH  
THURSDAY MORNING. SOME LIGHT PRECIPITATION IS POSSIBLE WEST OF THE  
MOUNTAINS LATE MONDAY NIGHT INTO TUESDAY, AND AGAIN TUESDAY NIGHT  
INTO EARLY WEDNESDAY, BUT WETTING RAINS ARE NOT EXPECTED.  
TEMPERATURES WILL BE WELL BELOW AVERAGE MUCH OF THE WORK WEEK, WITH  
SLOW WARMING EXPECTED NEXT WEEKEND.  
 
   
..DISCUSSION FROM PHXFWFPSR
 
 
WARMER THAN NORMAL TEMPERATURES AND DRY CONDITIONS WILL PERSIST  
THROUGH TUESDAY. AFTERNOON UPSLOPE GUSTS WILL BE COMMON HOWEVER  
SPEEDS WILL BE SOMEWHAT DAMPENED THROUGH THIS EVENING WITH THE HIGH  
CLOUD COVER AND WEAK GRADIENT FLOW. BREEZY TO LOCALLY WINDY  
CONDITIONS WILL DEVELOP TUESDAY, WITH GUSTS POTENTIALLY REACHING UP  
TO 35-40 MPH ACROSS SOUTHEAST CA AND THE LOWER COLORADO RIVER VALLEY  
IN THE AFTERNOON. A VERY DRY AIRMASS WILL REMAIN IN PLACE RESULTING  
IN AFTERNOON MINIMUM HUMIDITY VALUES AROUND 8-10% TODAY, BEFORE  
INCREASING INTO A 12-18% RANGE MONDAY AND TUESDAY. OVERNIGHT  
RECOVERIES WILL MOSTLY REBOUND INTO A 30-50% RANGE.
