AFTER MAKING LANDFALL EARLY THIS MORNING, TROPICAL STORM CINDY HAS
SLOWLY WEAKENED INTO A TROPICAL DEPRESSION AS IT MOVES FURTHER
INLAND NEAR THE LOUISIANA-TEXAS BORDER.  HEAVY TROPICAL DOWNPOURS
WILL CONTINUE TO ACCOMPANY THE CIRCULATION AS IT TRACKS
NORTHEASTWARD ACROSS ARKANSAS TONIGHT AND INTO THE TENNESSEE
VALLEY ON FRIDAY.  MEANWHILE, A FAST-MOVING COLD FRONT CURRENTLY
MOVING ACROSS THE UPPER MIDWEST AND THE CENTRAL PLAINS WILL
APPROACH AND BEGIN TO INTERACT WITH THE REMNANT CIRCULATION OF
CINDY ON FRIDAY.  THIS INTERACTION WILL INCREASE THE LIKELIHOOD OF
HEAVY RAIN AS THE REMNANTS OF CINDY CONTINUES TO TRACK ACROSS THE
THE TENNESSEE VALLEY FRIDAY NIGHT AND ACROSS THE CENTRAL
APPALACHIANS EARLY ON SATURDAY.  BY SATURDAY MORNING, THE CENTER
OF CINDY COULD PASS VERY NEAR THE NATION`S CAPITAL BEFORE RAPIDLY
OFF CAPE COD SATURDAY EVENING.  A PERIOD OF HEAVY RAIN WITH SOME
GUSTY WINDS CAN BE EXPECTED NEAR CINDY`S TRACK.  A COLD FRONT WILL
THEN QUICKLY SWEEP ACROSS IN THE WAKE OF CINDY, USHERING IN COOLER
AND DRIER AIR INTO THE EAST COAST BY SATURDAY EVENING.

BEFORE THE COLD FRONT REACHES THE EAST COAST SATURDAY EVENING,
SHOWERS AND THUNDERSTORMS CURRENTLY OVER THE MIDWEST INTO THE
GREAT LAKES COULD BECOME SEVERE INTO TONIGHT.  THE NORTHERN EXTENT
OF THE FRONT WILL BRING SHOWERS AND THUNDERSTORMS ACROSS THE
NORTHEAST ON FRIDAY INTO SATURDAY MORNING.  SOUTH OF THE FRONT AND
EAST OF THE REMNANTS OF CINDY, BANDS OF THUNDERSTORMS CAN BE
EXPECTED ACROSS ALABAMA AND INTO THE SOUTHERN APPALACHIANS THROUGH
SATURDAY BEFORE THE COLD FRONT ARRIVES.

OUT WEST, EXCESSIVE HEAT WITH ACTUALLY TEMPERATURES REACHING 120
DEGREES CONTINUES ACROSS THE DESERT SOUTHWEST.  THE HEAT IS
FORECAST TO BEGIN ABATING AS WE HEAD INTO THE WEEKEND.  ON THE
OTHER HAND, HOT WEATHER IS EXPECTED TO RETURN ACROSS THE PACIFIC
NORTHWEST WITH HIGH TEMPERATURES APPROACHING 100 DEGREES AT SOME
INTERIOR LOCATIONS DURING THE WEEKEND.
