...RAIN EVENTUALLY TAPERING OFF IN NEW ENGLAND...

...STORMY WEATHER CONTINUES FOR THE PACIFIC NORTHWEST...

...SOAKING RAINS EXPECTED FOR SOUTHERN FLORIDA...


THE LOW MOVING ALONG THE NORTHEAST COASTLINE HAS BROUGHT SOAKING
RAINS TO THE REGION THE LAST FEW DAYS.  THE MODERATE SHOWERS WILL
BEGIN MOVING INTO NEW ENGLAND BY THURSDAY EVENING. THERE COULD BE
MODERATE TO HEAVY SHOWERS FROM THURSDAY NIGHT TO FRIDAY AFTERNOON
FOR NEW ENGLAND WHICH COULD LEAD TO POSSIBILITY OF FLASH FLOODING.
 HOWEVER, THIS IS NOT EXPECTED TO BE WIDESPREAD.  SEE WPC`S
EXCESSIVE RAINFALL PRODUCT FOR MORE INFORMATION.  BY FRIDAY
MORNING, THE SURFACE LOW WILL BEGIN PULLING AWAY FROM THE NEW
ENGLAND COAST; CONSEQUENTLY, THE MODERATE SHOWERS WILL SUBSIDE
SOMETIME FRIDAY EVENING.

THE PACIFIC NORTHWEST SHOULD EXPECT CONTINUOUS SHOWERS OVER THE
NEXT FEW DAYS AS SEVERAL FRONTS MOVE OVER THE AREA THROUGHOUT THE
SHORT TERM PERIOD.  CURRENTLY, A COLD FRONT STRETCHED FROM THE
NORTHERN ROCKIES TO NORTHERN CALIFORNIA IS BRINGING WIDESPREAD
SHOWERS WITH POCKETS OF MODERATE RAINFALL.  A STATIONARY FRONT
WILL STAY DRAPED ALONG THE INTERMOUNTAIN WEST TO THE PACIFIC COAST
THROUGHOUT FRIDAY AND WILL PROVIDE FOCUS FOR PRECIPITATION.  BY
FRIDAY NIGHT AND INTO SATURDAY MORNING, A DEEPENING SURFACE LOW IN
THE PACIFIC WILL APPROACH THE WEST COAST.  AS IT GETS CLOSER,
SHOWERS WILL BECOME WIDESPREAD ALONG THE COASTLINE.

A STATIONARY FRONT WILL STAY SOUTH OF THE FLORIDA KEYS THROUGH
SATURDAY.  WIDESPREAD SHOWERS AND THUNDERSTORMS WILL BE EXPECTED
FOR MUCH OF THE SOUTHERN HALF OF FLORIDA.  THE FLORIDA KEYS WILL
LIKELY RECEIVE THE HEAVIEST AMOUNT OF RAINFALL.

***RAINY WEATHER CONTINUES FOR THE PACIFIC NORTHWEST***

***NOR`EASTER CONTINUES TO AFFECT NEW ENGLAND***

***HEAVY RAIN AND THUNDERSTORMS FOR SOUTH FLORIDA***

AN ACTIVE WEATHER PATTERN CONTINUES ACROSS THE PACIFIC NORTHWEST,
WITH STRONG ONSHORE FLOW BRINGING IN MOISTURE FROM THE PACIFIC
OCEAN, WITH THE GREATEST RAINFALL OVER THE COASTAL MOUNTAIN RANGES
AND THE CASCADES.  BY FRIDAY MORNING, INCREASED RIDGING ALOFT
ACROSS THE REGION SHOULD HELP TO REDUCE THE AMOUNT OF RAIN
COVERAGE.  SEVERAL INCHES OF RAINFALL IS POSSIBLE IN THESE AREAS,
AND THIS MAGNITUDE OF RAINFALL COULD LEAD TO SOME FLASH FLOODING.
ANY SNOWFALL SHOULD BE CONFINED TO THE HIGHEST ELEVATIONS OF THE
CASCADES.

SHOWERS AND A FEW THUNDERSTORMS ARE EXPECTED NEAR AND AHEAD OF A
WEAKENING FRONTAL ZONE MOVING ACROSS THE MIDWEST STATES.  ACROSS
THE NORTHEAST U.S., A SLOW MOVING COASTAL STORM WILL CONTINUE TO
BRING PERIODS OF RAIN GOING INTO EARLY FRIDAY.  BY FRIDAY EVENING,
THE CYCLONE PULLS SLOWLY AWAY FROM THE REGION AND ALLOWS FOR
IMPROVING CONDITIONS FROM WEST TO EAST.  A FEW INCHES OF RAIN IS
POSSIBLE OVER PARTS OF NEW ENGLAND THROUGH THE END OF THE WEEK.

ACROSS SOUTHERN FLORIDA AND THE KEYS, PERIODS OF HEAVY RAIN WITH
EMBEDDED THUNDERSTORMS IS FORECAST TO CONTINUE THROUGH THURSDAY
EVENING AS MOISTURE FROM A WEAK TROPICAL LOW INTERSECTS A
STATIONARY FRONT TO ITS NORTHEAST.  THE HEAVIEST RAINFALL IS
LIKELY OVER THE FLORIDA KEYS.

...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.
