...THUNDERSTORMS EXPECTED ACROSS THE SOUTHEAST AND CAROLINAS...

...COOLER TEMPERATURES WILL CONTINUE TO PREVAIL THE EASTERN U.S.
WITH WARMER WEATHER ACROSS THE WEST AND PLAINS...


AN UPPER LOW CONTINUES TO DIG ACROSS THE SOUTHEAST WHILE A STRONG
COLD FRONT WILL MOVE ACROSS THE SOUTHEAST, FLORIDA, AND THE
CAROLINAS.  COPIOUS AMOUNTS OF MOISTURE WILL STREAM ACROSS
NORTHERN FLORIDA AND SOUTHERN GEORGIA WHILE THE COLD FRONT WILL
ACT AS A FOCAL POINT TO SET OFF CONVECTION.  CONSEQUENTLY, HEAVY
RAIN WILL IMPACT THESE REGIONS AS THE COLD FRONT PUSHES SOUTH AND
EAST.  BY EARLY THURSDAY MORNING, HEAVY RAINFALL WILL SHIFT TOWARD
CENTRAL FLORIDA AHEAD OF THE COLD FRONT AND SLOWLY MOVES TOWARD
SOUTH FLORIDA. AS THE FRONT STALLS ON FRIDAY MORNING IN SOUTH
FLORIDA, SHOWERS AND THUNDERSTORMS WILL LINGER IN THIS REGION AND
THE FLORIDA KEYS.

THE PRIMARY LOW FOR THE AFOREMENTIONED COLD FRONT WILL PROGRESS
NORTHEAST IN THE OHIO VALLEY AND WILL APPROACH THE MID-ATLANTIC
AND NORTHEAST BY TONIGHT.  PRECIPITATION WILL INCREASE IN THESE
AREAS BY LATE TONIGHT AND CONTINUE FOR THURSDAY. ANOTHER LOW WILL
FORM IN DELMARVA ON THURSDAY MORNING AND TAKE OVER WHILE SLIDING
ALONG THE NEW ENGLAND COAST.  THIS WILL CAUSE HEAVY RAINFALL
THROUGHOUT THURSDAY AND FRIDAY THROUGHOUT THE NEW ENGLAND AREA;
EXPECT THE HEAVIER RAINFALL TO TAPER OFF BEGINNING FRIDAY NIGHT.
OVERALL, FLASH FLOODING WILL BE A CONCERN ALONG THE CENTRAL AND
SOUTHERN APPALACHIANS AS OROGRAPHICS WILL ENHANCE PRECIPITATION
ACROSS THESE MOUNTAINS.

ANOTHER UPPER LEVEL LOW WILL MOVE ACROSS THE INTERMOUNTAIN WEST
AND TOWARD THE PLAINS TONIGHT AND INTO THURSDAY.  A SURFACE FRONT
WILL MOVE ACROSS THE INTERMOUNTAIN WEST; HOWEVER, MOISTURE WILL BE
LIMITED SO NOT MUCH PRECIPITATION IS EXPECTED.  ONCE THE FRONT
MOVES INTO THE PLAINS, SHOWERS WILL MOVE ALONG AND AHEAD OF THE
BOUNDARY.  PRECIPITATION WILL BEGIN TO INCREASE ALONG THE CENTRAL
PLAINS AND INTO THE CENTRAL ROCKIES ON THURSDAY AND WILL LINGER
ACROSS THE WEST AS THE FRONT STALLS FROM THE CENTRAL BASIN TO THE
FRONT RANGE OF COLORADO.  THE HEAVIEST RAINFALL IS EXPECTED TO
FALL ALONG NORTHWEST KANSAS INTO THE BEGINNING OF THE WEEKEND.

COOLER TEMPERATURES WILL CONTINUE ACROSS THE EAST COAST WITH
WARMER TEMPERATURES IN THE WESTERN U.S.  BY THURSDAY, COOLER
TEMPERATURES ARE EXPECTED IN THE INTERMOUTAIN WEST/CENTRAL BASIN
AS PRECIPITATION INCREASES IN THIS AREA AND WARMER TEMPERATURES
WILL SHIFT TO THE SOUTHERN PLAINS.
