...DRYER CONDITIONS ACROSS THE MID-ATLANTIC TODAY, WITH SHOWERS  
AND THUNDERSTORMS MOVING THROUGH THE NORTHEAST...  
 
...SEVERE THUNDERSTORMS AND LOCALLY HEAVY RAINFALL POSSIBLE BY  
TUESDAY EVENING ACROSS PARTS OF THE NORTHERN PLAINS...  
 
...ABOVE NORMAL AND CLOSE TO RECORD BREAKING TEMPERATURES WILL  
CONTINUE FOR PORTIONS OF THE SOUTHERN PLAINS TO THE SOUTHEAST...  
 
THE LOW PRESSURE SYSTEM RESPONSIBLE FOR PROLONGED PERIODS OF RAIN  
AND FLOODING ACROSS THE MID-ATLANTIC THE PAST FEW DAYS WILL  
FINALLY PULL AWAY FROM THE COAST TODAY. DRYER CONDITIONS ARE  
EXPECTED ON MONDAY, BUT FLOODING OF AREA STREAMS AND RIVERS MAY  
CONTINUE FOR ANOTHER COUPLE OF DAYS. TO THE NORTH, AN UPPER LEVEL  
LOW ROTATING THROUGH THE NORTHEAST WILL BRING SHOWERS AND  
THUNDERSTORMS TO THE REGION TODAY WITH ANOTHER ROUND OF SCATTERED  
SHOWERS AND STORMS ACROSS THE MID-ATLANTIC INTO THE NORTHEAST AS A  
FRONTAL BOUNDARY MOVES THROUGH ON TUESDAY AFTERNOON. THE WESTERN  
PORTION OF THE BOUNDARY IS FORECAST TO STALL ACROSS THE GULF COAST  
WHICH SHOULD KEEP MAINLY SCATTERED SHOWERS IN THE FORECAST THE  
NEXT FEW DAYS. RETURN MOISTURE OFF THE GULF OF MEXICO INTO TEXAS  
WILL ALLOW FOR ANOTHER COUPLE OF DAYS OF CONVECTION, WITH A  
MARGINAL RISK FOR SEVERE WEATHER, AS THIS MOISTURE INTERSECTS A  
DRYLINE AND WEAK FRONTAL BOUNDARY.  
 
A COLD FRONT MOVING INTO THE NORTHERN ROCKIES THIS MORNING WILL  
ALLOW FOR MAINLY LIGHT PRECIP ALONG THE BOUNDARY TODAY. THE COLD  
FRONT SHOULD REACH THE NORTHERN PLAINS BY TUESDAY, AND MOISTURE  
STREAMING NORTHWARD ACROSS THE GREAT PLAINS WILL INTERACT WITH  
IMPULSES OF UPPER LEVEL ENERGY INCREASING THE CHANCES FOR SHOWERS  
AND THUNDERSTORMS ACROSS THE DAKOTAS. THUNDERSTORMS MAY BE CAPABLE  
OF PRODUCING HEAVY RAINFALL AND SEVERE WEATHER, ESPECIALLY TUESDAY  
EVENING AND EARLY WEDNESDAY MORNING ACROSS NORTH DAKOTA NEAR A  
DEVELOPING SURFACE LOW.  
 
TEMPERATURE WISE, THE NORTHEAST WILL BE COOLER THAN NORMAL UNDER  
THE INFLUENCE OF UPPER LEVEL TROUGHING. MUCH OF THE CENTRAL U.S.  
AND THE WEST WILL BE WARM. AFTERNOON HIGHS IN THE MID TO UPPER 90S  
ARE EXPECTED ACROSS MUCH OF THE GREAT PLAINS AS WELL AS THE DESERT  
SOUTHWEST, WHICH IS ABOUT 10 TO 20 DEGREES ABOVE NORMAL FOR THIS  
TIME OF THE YEAR.
