VALID 12Z MON JUN 04 2018 - 12Z WED JUN 06 2018  
 
...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...  
 
...WELL ABOVE NORMAL TEMPERATURES EXPECTED THE NEXT FEW DAYS  
ACROSS THE GREAT PLAINS AND INTO THE DESERT SOUTHWEST, WITH BELOW  
NORMAL VALUES FOR THE NORTHEAST...  
 
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 PRECIPITATION 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 THE GREAT PLAINS AS WELL AS THE DESERT  
SOUTHWEST, WHICH IS ABOUT 10 TO 20 DEGREES ABOVE NORMAL FOR THIS  
TIME OF THE YEAR.
