...STORMY WEATHER ACROSS THE NORTHEAST, PACIFIC NORTHWEST, AND
SOUTHERN FLORIDA...


LOW PRESSURE CURRENTLY OFF THE MID-ATLANTIC COAST WILL SLOWLY MOVE
NORTHEASTWARD OVER THE NEXT FEW DAYS.  THIS HAS ALREADY DELIVERED
A FAIR AMOUNT OF RAIN TO THE MID-ATLANTIC REGION. HEAVIER POCKETS
OF RAIN HAVE BEEN MOVING ACROSS THE NORTHEAST/NEW ENGLAND REGION
ON WEDNESDAY AND WILL CONTINUE TO DO SO THROUGH FRIDAY.  FLASH
FLOODING IS A POSSIBILITY AND WILL BE CONFINED SPECIFICALLY TO NEW
ENGLAND ON WEDNESDAY AND THURSDAY.  PRECIPITATION WILL TAPER OFF
BY FRIDAY AFTERNOON AS THE LOW PROGRESSES TOWARD NOVA SCOTIA.

QUITE THE BUSY PATTERN CAN BE EXPECTED FOR THE PACIFIC NORTHWEST.
ON WEDNESDAY, A COLD FRONT MOVED INLAND ACROSS WASHINGTON STATE
AND OREGON.  THIS IS BRINGING LIGHT TO MODERATE SHOWERS FROM
BRITISH COLUMBIA TO NORTHERN CALIFORNIA AND WILL PERSIST THROUGH
THURSDAY.  BY THURSDAY EVENING, THE COLD FRONT WILL STRETCH ACROSS
THE GREAT BASIN AND NORTHERN CALIFORNIA.  BY THIS TIME, MOST OF
THE PRECIPITATION AROUND THE PACIFIC NORTHWEST REGION WILL BE
LIGHTER AROUND WITH THE EXCEPTION OF NORTHERN CALIFORNIA WHERE
MODERATE SHOWERS ARE POSSIBLE.  HOWEVER, WITH ANOTHER INCOMING
SYSTEM FROM THE PACIFIC APPROACHES THE WEST COAST, SHOWERS WILL
LAST THROUGH THURSDAY.

WITH A STATIONARY FRONT DRAPED SOUTH OF THE FLORIDA KEYS, SOUTHERN
FLORIDA CAN EXACT HEAVY SHOWERS AND THUNDERSTORMS THROUGH
WEDNESDAY NIGHT AND INTO THURSDAY. THE FLORIDA KEYS ESPECIALLY
WILL RECEIVE THE BULK OF THE HEAVIER RAINFALL ACTIVITY.
PRECIPITATION WILL LIGHTEN UP SLIGHTLY BY THURSDAY EVENING;
HOWEVER, THE STATIONARY FRONT WILL STAY PUT SOUTH OF THE KEYS
THROUGHOUT THE SHORT TERM PERIOD, THUS STORMY WEATHER IS EXPECTED
TO REMAIN.

A LINE OF SHOWERS AND SOME EMBEDDED THUNDERSTORMS WILL CONTINUE TO
MOVE ACROSS THE PLAINS WITH AN OCCLUDED FRONT PROGRESSING EASTWARD
TOWARD THE MISSISSIPPI VALLEY.  THE RAINFALL IN TEXAS WILL END BY
THURSDAY MORNING.  THE UPPER MIDWEST AND MISSISSIPPI VALLEY CAN
EXPECT TO SEE PRECIPITATION BY THURSDAY AFTERNOON.  THE SHOWERS
WILL BEGIN TO DWINDLE IN COVERAGE BY FRIDAY MORNING.
