...HEAVY RAIN AND SNOW TO BE DELIVERED THROUGHOUT THE EASTERN U.S.  
AS AN IMPRESSIVE STORM SYSTEM SWEEPS ACROSS THE AREA...  
 
A STRONG COLD FRONT MOVING OVER THE MISSISSIPPI VALLEY WILL  
CONTINUE ITS EASTWARD TREK TOWARD THE EAST COAST THROUGH MIDWEEK.  
ON MONDAY EVENING, SHOWERS AND THUNDERSTORMS WILL MOVE FROM THE  
UPPER MIDWEST TO THE SOUTHERN PLAINS. SOME OF THE CONVECTIVE  
ACTIVITY IN THE LOWER MISSISSIPPI VALLEY MAY GIVE WAY TO FLASH  
FLOODING--CREATING A MARGINAL RISK FOR FLASH FLOODING. AREAS NORTH  
AND WEST OF THE LOW--IN THE NORTHERN/CENTRAL PLAINS AND PARTS OF  
THE UPPER MIDWEST--CAN EXPECT LIGHT TO MODERATE SNOW TONIGHT AND  
INTO TOMORROW.  
 
BY TUESDAY, THE COLD FRONT WILL STRETCH FROM THE NORTHEAST TO THE  
SOUTHERN PLAINS. THE LINE OF SHOWERS AND THUNDERSTORMS WILL  
CONTINUE MOVING ALONG AND AHEAD OF THE BOUNDARY. THERE COULD BE  
HEAVY RAINFALL IN PARTS OF THE SOUTHEAST ON TUESDAY  
AFTERNOON--THUS A MARGINAL RISK OF FLASH FLOODING IS POSSIBLE.  
PRECIPITATION IS EXPECTED TO SPREAD ACROSS THE SOUTHEAST,  
MID-ATLANTIC, AND NORTHEAST THROUGHOUT THE DAY. BY WEDNESDAY  
MORNING, MOST OF THE PRECIPATION WILL MOVE OFF THE EAST COAST AS  
THE FRONT EXITS TO THE ATLANTIC. HOWEVER, AS THE FRONT MOVES  
SOUTHWARD OVER FLORIDA--IT WILL ALSO BRING SHOWERS AND  
THUNDERSTORMS WITH IT. LINGERING PRECIPTITION CAN ALSO BE  
EXPECTED ACROSS TEXAS.
