...A STRONG COLD FRONT WILL DELIVER SHOWERS AND THUNDERSTORMS TO  
THE EASTERN U.S...  
   
..CRITICAL FIRE WEATHER CONTINUES ACROSS THE WEST COAST
 
 
THE STRONG COLD FRONT STRETCHED FROM THE GREAT LAKES TO THE  
SOUTHERN PLAINS WILL CONTINUE MOVING EASTWARD OVER THE SHORT TERM  
PERIOD. A LINE OF SHOWERS AND THUNDERSTORMS WILL FOLLOW ALONG THE  
BOUNDARY. THE THREAT OF FLASH FLOODING AND SEVERE WEATHER  
DIMINISHES ON SUNDAY, HOWEVER, AS MOST OF THE PRECIPITATION WILL  
BE MUCH LIGHTER AND MOVING VERY QUICKLY WITH THE FRONT. BY MONDAY  
MORNING, THE FRONT, ALONG WITH THE PRECIPITATION, WILL APPROACH  
THE EAST COAST IN ADDITION TO MOVING THROUGH THE CENTRAL GULF  
COAST REGION. AS THE FRONT MOVES SOUTHWARD ACROSS FLORIDA ON  
TUESDAY, SHOWERS AND THUNDERSTORMS WILL LINGER IN THE CENTRAL AND  
SOUTHERN PORTIONS OF THE PENINSULA. BEHIND THE FRONT, COOL AND DRY  
CONDITIONS WILL SETTLE--BRINGING FALL-LIKE WEATHER TO MUCH OF THE  
EASTERN HALF OF THE COUNTRY.  
 
AN UPPER LEVEL RIDGE WILL BE CENTERED OVER THE WEST COAST WHICH  
WILL KEEP THIS PORTION OF THE U.S. VERY DRY AND WARMER THAN  
NORMAL. THESE INGREDIENTS COMBINED WITH DRY, GUSTY SOUTHWESTERLY  
WINDS, CRITICAL FIRE WEATHER CONDITIONS WILL EXIST ESPECIALLY TO  
SOUTHERN CALIFORNIA ON SUNDAY. BY MONDAY, THE UPPER LEVEL RIDGE  
WILL WEAKEN; HOWEVER, ELEVATED FIRE WEATHER CONDITIONS WILL BE IN  
PLACE IN SOUTHEASTERN WYOMING. FOR MORE INFORMATION ON THIS,  
PLEASE SEE THE FIRE WEATHER PRODUCTS FROM THE STORM PREDICTION  
CENTER (WWW.SPC.NOAA.GOV).
