DISCUSSION
 
 
DRY WEATHER CONTINUES INTO MONDAY AND SOME GUSTY WINDS ARE  
EXPECTED BUT THE STRENGTH AND COVERAGE WILL BE LESS THAN SEEN OVER  
THE LAST FEW DAYS. SOME LOCALIZED AREAS MAY SEE BRIEF RED FLAG  
CONDITIONS BUT NOT ENOUGH TO WARRANT ANY HIGHLIGHTS. A SLOW MOVING  
SYSTEM WILL MOVE THROUGH THE AREA TUESDAY ONWARDS AND WILL BRING  
UNSETTLED, AND EVENTUALLY, COOLER WEATHER TO THE REGION. WINDS  
AHEAD OF THE SYSTEM MAY BRING SOME CRITICAL FIRE WEATHER CONCERNS  
TO SOUTHERN AREAS WEDNESDAY BUT CONCERNS SHOULD DIMINISH AFTER  
THAT.  
 
...GUSTY ERRATIC WINDS CAN BE EXPECTED NEAR ANY SHOWERS  
OR THUNDERSTORMS...   
..THE SMOKE DATA IS CALCULATED FROM AN AVERAGE AT 6000 FEET MSL
