NEXT FEW DAYS...

UNSEASONABLY COOL TEMPERATURES, WITH SHOWERS AND THUNDERSTORMS,
WILL CONTINUE NORTH OF A COLD FRONT THAT HAS SETTLED INTO SOUTHERN
TEXAS. A SERIES OF UPPER LEVEL DISTURBANCES INTERACTING WITH A
MOIST ATMOSPHERE IS EXPECTED TO PRODUCE PERIODS OF SHOWERS AND
THUNDERSTORMS ACROSS PORTIONS OF THE SOUTHERN PLAINS OVER THE NEXT
FEW DAYS, WITH HEAVY RAINFALL AMOUNTS AND FLOODING POSSIBLE.
IT WILL REMAIN UNSETTLED, WITH SEASONAL TO BELOW-AVERAGE
TEMPERATURES, ACROSS MUCH OF THE SOUTHWEST TODAY AS WELL. THEN
DRIER AIR WILL SUPPORT A DIMINISHING CHANCE FOR SHOWERS AND
THUNDERSTORMS, AS TEMPERATURES BEGIN TO CLIMB DURING THE LATTER
HALF OF THE WEEK.
FARTHER TO THE NORTH, A COLD FRONT WILL FOCUS SHOWERS AND
THUNDERSTORMS AS IT ADVANCES SOUTHEAST FROM THE NORTHERN ROCKIES
AND GREAT BASIN TODAY, INTO THE NORTHERN PLAINS, UPPER MIDWEST,
AND THE CENTRAL ROCKIES ON THURSDAY.
IN THE EAST, A COLD FRONT WILL SLOWLY ADVANCE EAST TODAY,
PRODUCING ADDITIONAL SHOWERS AND THUNDERSTORMS ALONG THE EASTERN
SEABOARD, WITH HEAVY RAINFALL AMOUNTS POSSIBLE, ESPECIALLY FOR
PARTS OF THE NORTHEAST. FLOOD WATCHES REMAIN IN EFFECT FOR AT
LEAST OF PORTION OF TODAY FROM EASTERN PENNSYLVANIA, NORTHERN
DELAWARE, AND NEW JERSEY INTO SOUTHEASTERN NEW YORK AND SOUTHERN
NEW ENGLAND, WHERE LOCALLY HEAVY DOWNPOURS MAY RESULT IN EXCESSIVE
RUNOFF.
ALSO ALONG THE EAST COAST -- EVEN THOUGH HURRICANE LEE REMAINS
WELL OFFSHORE, THE STORM IS ALREADY PRODUCING DANGEROUS SURF AND
RIP CURRENTS ALONG PORTIONS OF THE SOUTHEAST COAST. THESE
CONDITIONS ARE FORECAST TO SPREAD NORTHWARD ALONG THE REMAINDER OF
THE EAST COAST OVER THE NEXT COUPLE OF DAYS.
