..DISCUSSION FROM RNOFWFVEF
 
 
CONDITIONS WILL FINALLY BEGIN TO COOL EARLY THIS WEEK AS A WEATHER  
SYSTEM MOVES ACROSS THE WESTERN STATES. THIS SYSTEM WILL BRING  
INCREASED WINDS TO MUCH OF THE REGION, ESPECIALLY MONDAY. A FEW  
AREAS WILL SEE GUSTS NEAR 35 MPH, LEADING TO CRITICAL FIRE  
CONDITIONS. OUTSIDE OF A FEW ISOLATED SHOWERS/STORMS TODAY, DRY  
CONDITIONS ARE EXPECTED THIS WEEK.  
 
   
..DISCUSSION FROM LAXFWFSGX
 
 
HIGH PRESSURE ALOFT WILL CONTINUE THE HOT DRY WEATHER INLAND INTO  
MONDAY WHILE A SHALLOW MARINE LAYER KEEPS COASTAL AREAS COOLER WITH  
HIGHER HUMIDITY. THE HIGH WILL BEGIN TO WEAKEN ON MONDAY AS A WEAK  
DISTURBANCE MOVES INLAND. THIS WILL CAUSE THE ONSHORE FLOW TO  
INCREASE, AND LOWER HUMIDITY AT HIGHER ELEVATIONS AND INTO THE  
DESERTS. BEFORE THE MARINE LAYER DEEPENS APPRECIABLY, THE HOT AND  
DRY CONDITIONS INLAND, COUPLED WITH THE INCREASING WESTERLY WINDS,  
WILL CREATE PERIODS OF CRITICAL FIRE WEATHER CONDITIONS FROM THE  
MOUNTAIN CRESTS ONTO THE DESERT SLOPES, AND LOCALLY INTO THE  
DESERTS MONDAY AND TUESDAY. WINDS WILL BE STRONGEST LATE AFTERNOON  
AND EVENINGS MONDAY AND TUESDAY, AND MAY CONTINUE THROUGH MONDAY  
NIGHT INTO TUESDAY MORNING. CONDITIONS WILL IMPROVE BY WEDNESDAY AS  
WINDS SUBSIDE AND HUMIDITY INCREASES.  
 
   
..DISCUSSION FROM PHXFWFPSR
 
 
INCREASING WESTERLY FLOW ALOFT TO THE SOUTH OF A SERIES OF PACIFIC  
STORM SYSTEMS MOVING INLAND ACROSS THE NORTHERN GREAT BASIN IS  
EXPECTED TO PUSH DRIER AND SLIGHTLY COOLER AIR INTO THE REGION  
DURING THE EARLY/MIDDLE PART OF THE UPCOMING WORKWEEK, WITH THE  
THREAT OF CONVECTIVE ACTIVITY BEING PUSHED WELL OFF TO THE EAST,  
INTO NEW MEXICO/WEST TEXAS. THE COMBINATION OF VERY DRY AIR AND  
GUSTY WINDS IS EXPECTED TO INCREASE FIRE DANGER LEVELS ACROSS SE  
CA ON MONDAY.
