...STRONG COLD FRONT TO DELIVER HEAVY RAINFALL ACROSS THE EASTERN  
U.S...  
 
A VERY STRONG COLD FRONT WILL SWEEP ACROSS THE EASTERN U.S. WHILE  
BRINGING HEAVY RAINFALL AND EVEN SNOW ACROSS MANY REGIONS. THE  
LINE OF SHOWERS AND THUNDERSTORMS CURRENTLY MOVING ACROSS THE OHIO  
VALLEY TO THE CENTRAL GULF COAST WILL CONTINUE MOVING  
EASTWARD--WITH A SLIGHT RISK OF FLASH FLOODING ACROSS A SMALL  
PORTION OF THE CENTRAL GULF COAST REGION. AS THE COLD FRONT  
APPROACHES THE MID-ATLANTIC, HEAVY RAINFALL WILL ENTER THE  
APPALACHIANS AND LOWER GREAT LAKES BY SATURDAY AFTERNOON. BY  
SUNDAY, MOST OF THE HEAVY RAINFALL WILL OCCUR IN THE NORTHEAST AND  
NEW ENGLAND--WITH A SLIGHT CHANCE OF FLASH FLOODING. THIS  
RAINFALL WILL LINGER THROUGH MOST OF THE DAY AND INTO MONDAY  
MORNING. IN ADDITION, ANOTHER THREAT TO THIS SYSTEM WILL BE  
STRONG, GUSTY WINDS THROUGHOUT THE MID-ATLANTIC AND NORTHEAST.  
MOST OF THE SNOWFALL ACTIVITY IS EXPECTED IN THE UPPER GREAT LAKES  
ON SATURDAY; BY SUNDAY, THERE COULD BE VERY LIGHT SNOW SHOWERS IN  
THE HIGHER ELEVATIONS OF THE WEST VIRGINIA MOUNTAINS.  
 
COOL AND SEASONABLE TEMPERATURES WILL FOLLOW IN THE WAKE OF THIS  
STRONG COLD FRONT--MOSTLY FROM THE GULF COAST TO THE NORTHEAST.  
WITH A STUBBORN UPPER RIDGE DOMINATING THE WEST COAST, HIGH  
TEMPERATURES WILL BE 10-15 DEGREES ABOVE AVERAGE THROUGH THE  
WEEKEND.
