THE OPPRESSIVE HEAT THAT`S BEEN OVER MUCH OF THE EASTERN STATES
WILL SLOWLY LESSEN THROUGH MIDWEEK. A COLD FRONT IS FORECAST TO
PUSH THROUGH THE NORTHEAST AND MID-ATLANTIC ON TUESDAY, WITH
ANOTHER COLD FRONT DIVING SOUTHWARD FROM SOUTHERN CANADA BY
WEDNESDAY EVENING. ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS
WILL BE POSSIBLE ACROSS THE MID-ATLANTIC REGION TONIGHT. SOME
THUNDERSTORMS COULD BE SEVERE ACROSS THE MID-ATLANTIC. PLEASE

FURTHER DETAILS ON THE SEVERE WEATHER THREAT.

PRECIPITATION WILL BE MINIMAL ACROSS THE NORTHEAST AS SLIGHTLY
COOLER AND DRIER AIR STREAMS IN BEHIND THE FRONT.  A PORTION OF
THE FRONT WILL BE SLOW/QUASI-STATIONARY FROM THE APPALACHIANS TO
THE MIDDLE MISSISSIPPI VALLEY AND CENTRAL PLAINS THROUGH WEDNESDAY
BEFORE LIFTING AS A WARM FRONT THROUGH THE CENTRAL PLAINS AND
MIDDLE MISSISSIPPI VALLEY WEDNESDAY NIGHT AND BEYOND. SCATTERED
AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS WILL ALSO CONTINUE
ALONG THE BOUNDARY AND ACROSS THE GULF COAST AND SOUTHEASTERN
STATES OVER THE NEXT FEW DAYS. STORMS WILL BE MOST NUMEROUS ALONG
THE WESTERN AND CENTRAL GULF COAST WHERE DEEPER MOISTURE WILL BE
IN PLACE.

MUCH OF THE CENTRAL U.S. WILL HAVE RELIEF FROM THE OPPRESSIVE HEAT
AS THE UPPER-LEVEL RIDGE SHIFTS WESTWARD. NEAR OR SLIGHTLY BELOW
NORMAL TEMPERATURES WILL RETURN TO THE MUCH OF THE CENTRAL AND
SOUTHERN PLAINS. TEMPERATURES WILL CLIMB INTO THE UPPER 90S TO
100+ ACROSS PORTIONS OF THE GREAT BASIN AND DESERT SOUTHWEST THIS
