A LOW PRESSURE SYSTEM WILL CONTINUE MOVING EASTWARD ACROSS THE

AND TENNESSEE VALLEYS THROUGH TUESDAY NIGHT. ADDITIONALLY, THERE

THE APPALACHIANS AND MID-ATLANTIC ON WEDNESDAY, MOVING INTO THE  
NORTHEAST BY WEDNESDAY NIGHT. RAIN OF 1 TO 2 INCHES IS POSSIBLE,

SO SCATTERED THUNDERSTORMS ARE POSSIBLE, WHICH COULD BE SEVERE.  
RAIN AND THUNDERSTORMS WILL BE ON THE INCREASE FOR THE NORTHERN  
ROCKIES TO NORTHERN PLAINS ON THURSDAY AS A SURFACE LOW  
STRENGTHENS AHEAD OF AN UPPER-LEVEL TROUGH.  
 
HOT TEMPERATURES WILL REMAIN FOR MUCH OF THE WEST, THE CENTRAL AND  
SOUTHERN PLAINS, AND SPREADING INTO THE MIDDLE AND LOWER  
MISSISSIPPI VALLEY AND SOUTHEAST THROUGH THURSDAY. A FEW RECORD  
HIGHS ARE POSSIBLE IN THE CENTRAL HIGH PLAINS BY THURSDAY. THE  
RAIN AND CLOUDS WILL HELP HOLD TEMPERATURES DOWN BELOW AVERAGE IN  
THE MID-ATLANTIC ON WEDNESDAY, AND THE NORTHEAST IS FORECAST TO  
SEE BELOW AVERAGE TEMPERATURES ON THURSDAY.
