...POST-TROPICAL CYCLONE CINDY WILL MOVE QUICKLY NORTHEASTWARD
ALONG THE NORTHEAST U.S. COASTLINE TODAY...

...HEAVY RAIN AND FLASH FLOODING POSSIBLE FROM PORTIONS OF THE
GULF COAST STATES TO THE SOUTHEAST, AS WELL AS PORTIONS OF THE
SOUTHWEST...

...WELL ABOVE AVERAGE TEMPERATURES EXPECTED TO CONTINUE FOR MUCH
OF THE WESTERN U.S...

POST-TROPICAL CYCLONE CINDY IS MOVING QUICKLY EAST-NORTHEASTWARD
ACROSS THE MID-ATLANTIC REGION EARLY THIS MORNING, AND THE SYSTEM
IS EXPECTED TO CONTINUE TO ACCELERATE NORTHEASTWARD TODAY WHILE
GRADUALLY BECOMING ABSORBED IN A SURFACE FRONTAL SYSTEM BY LATE
AFTERNOON. THE COMBINATION OF CINDY AND THE FRONTAL BOUNDARY WILL
BRING SHOWERS AND THUNDERSTORMS TO MUCH OF THE NORTHEAST THIS
MORNING, WITH MOST AREAS BEGINNING TO DRY OUT DURING THE AFTERNOON
AS THE FRONT MOVES OFFSHORE. FARTHER SOUTH, THE COLD FRONT WILL
PRODUCE NUMEROUS SHOWERS AND THUNDERSTORMS TODAY ACROSS PORTIONS
OF THE GULF COAST STATES AND THE SOUTHEAST, WITH THE TAIL END OF
THE FRONT PRODUCING SHOWERS AND STORMS ACROSS PORTIONS OF THE
SOUTHWEST. THESE SHOWERS AND STORMS COULD PRODUCE HEAVY RAIN, AND
FLASH FLOODING IS POSSIBLE. THE FRONT WILL MAKE SLOW SOUTHWARD
PROGRESS BY SUNDAY, WITH AREAS OF SHOWERS AND THUNDERSTORMS
PERSISTING ALONG THE IMMEDIATE GULF COAST AS WELL AS ACROSS
EXTREME EASTERN PORTIONS OF GEORGIA AND THE CAROLINAS.

ACROSS THE WEST, HIGH PRESSURE AT THE MID AND UPPER-LEVELS WILL
HOLD STRONG THROUGH THE WEEKEND, WITH GENERALLY DRY CONDITIONS AND
ABOVE AVERAGE TEMPERATURES EXPECTED. THE MOST ANOMALOUS
TEMPERATURES WILL BE ACROSS THE PACIFIC NORTHWEST WHERE HIGHS ARE
FORECAST TO BE 15 TO 25 DEGREES ABOVE AVERAGE TODAY AND SUNDAY.
SOME LOCATIONS IN THE NORTHWEST AWAY FROM THE COAST ARE FORECAST
TO SURPASS 100 DEGREES. TEMPERATURES WILL ALSO REMAIN ABOVE
AVERAGE IN THE SOUTHWEST. WHILE NOT THE RECORD HEAT OF RECENT
DAYS, HIGH TEMPERATURES IN THAT REGION ARE EXPECTED TO BE 5 TO 15
DEGREES ABOVE AVERAGE.
