AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
418 PM EDT WED APR 6 2011

.SYNOPSIS...
A WAVE OF LOW PRESSURE WILL TRACK SOUTH OF NEW ENGLAND LATE
TONIGHT INTO THURSDAY. HIGH PRESSURE BUILDS SOUTH INTO NEW ENGLAND
LATE THURSDAY THROUGH SATURDAY. PERIODS OF SHOWERS MAY AFFECT THE
REGION LATE IN THE WEEKEND INTO EARLY NEXT WEEK AS A FRONTAL
SYSTEM APPROACHES.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
DRY WESTERLY FLOW AND MOSTLY SUNNY SKIES HAVE LED TO TEMPERATURES IN
THE MID 40S TO MID 50S THIS AFTERNOON.  WESTERLY FLOW WILL CONTINUE
AND MAY BRING A FEW SCATTERED SHOWERS INTO SOUTHERN NEW ENGLAND BUT
AT THIS TIME IT LOOKS LIKE THIS FLOW WILL GO TO THE NORTH AND SOUTH
OF THE REGION.  THE MORE NORTHERN SHOWERS ARE DUE TO A SHORTWAVE
MOVING OVER THE REGION WHILE THE SOUTHERN SHOWERS ARE A RESULT OF A
WARM FRONT PARKED JUST TO OUR SOUTHWEST.

TONIGHT...WE MAY SEE A FEW SHOWERS/SNOW SHOWERS ASSOCIATED WITH THE
WARM FRONT TO OUR SOUTH.  HAVE LIMITED POPS TO CHANCE FOR THIS
PERIOD WITH THE HIGHEST POPS TO THE SOUTH WHERE THE GREATEST AMOUNT
OF LIFT WILL BE.  USED A BLEND OF THE MOSGUIDE AND SREF POPS.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
CLOUDS MAY LINGER ALONG THE SOUTH COAST AT THE BEGINNING OF THE
DAY.  THEN HIGH PRESSURE BUILDS IN FROM CANADA RESULTING IN MOSTLY
CLEAR SKIES AND LIGHT WINDS.  NEAR NORMAL TEMPERATURES ARE
EXPECTED.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
HIGHLIGHTS
* DRY AND SEASONABLE FRIDAY AND SATURDAY
* A FEW SHOWERS POSSIBLE FROM TIME TO TIME SUNDAY THROUGH TUESDAY
* UNSEASONABLY WARM WEATHER POSSIBLE MONDAY

MODELS IN AGREEMENT WITH DIGGING TROF ACROSS WESTERN CONUS AND
RIDGE BUILDING OVER THE GT LAKES AND EASTERN US INTO THE WEEKEND
WITH MAINLY DRY NW FLOW OVER NEW ENG. PATTERN IS PROGRESSIVE AND
MID LEVEL TROF IS FORECAST TO EJECT EWD AND MOVE ACROSS NEW ENG BY
TUE. GENERALLY DRY WEATHER IS EXPECTED INTO THE WEEKEND...THEN A
FEW SHOWERS POSSIBLE SUNDAY IN DEVELOPING WAA PATTERN AND AGAIN
LATE MON INTO TUE AS COLD FRONT APPROACHES. UNSEASONABLY WARM
WEATHER POSSIBLE MON AS WARM SECTOR AIRMASS MOVES INTO SNE.

FRIDAY AND SATURDAY...
HIGH PRESSURE IN CONTROL WHICH WILL KEEP DEEPER MOISTURE AND
SHOWERS CONFINED TO THE SOUTH. EXPECT MOSUNNY SKIES BOTH DAYS WITH
PERIOD OF HIGH CLOUDS. SEABREEZES EXPECTED FRIDAY ON BOTH COASTS
WHICH WILL KEEP TEMPS IN THE UPPER 40S BUT WARMING INTO THE
MID/UPPER 50S FURTHER IN THE INTERIOR. ON SAT...HIGH PRES BEGINS
TO SHIFT EWD AND WINDS BECOME SOUTHERLY WHICH SHOULD ALLOW MILDER
TEMPS INTO THE UPPER 50S TO LOWER 60S...EXCEPT LOWER 50S S COAST.

SUNDAY...
HIGH PRES MOVES WELL OFFSHORE WITH INCREASING S/SW FLOW
DEVELOPING. INCREASING WAA WILL RESULT IN CONSIDERABLE CLOUDS AND
A FEW SHOWERS ARE POSSIBLE. BEST CHANCE WILL BE TO THE NORTH BUT
WE INTRODUCED LOW CHC POPS ACROSS THE REGION. WARMING LOW AND MID
LEVEL TEMPS WILL BE OFFSET BY CLOUDS AND COOLING SOUTHERLY FLOW SO
TEMPS LIKELY HOLDING IN UPPER 50S TO LOWER 60S...COOLER S COAST.

MONDAY...
GFS AND ECMWF INDICATE WARM FRONT LIFTING N OF THE REGION WITH
WARM SECTOR AIRMASS ACROSS SNE. 850 MB TEMPS QUITE WARM FOR THIS
TIME OF YEAR...REACHING 14-17C. WE WONT ACHIEVE FULL MIXING TO
850 MB DUE TO SW FLOW...BUT POTENTIAL FOR UNSEASONABLY WARM TEMPS
IN THE 70S FOR THE INTERIOR . THERE IS A LOW PROB FOR A FEW 80
DEGREE READINGS PER GFS/ECMWF 2M TEMPS IF THERE IS SUFFICIENT
SUNSHINE. TEMPS MUCH COOLER NEAR S COAST.

MUCH OF THE DAY SHOULD BE DRY WITH PTSUNNY SKIES BUT CANT RULE
OUT A FEW STRAY SHOWERS IN THE INTERIOR ESPECIALLY LATE IN THE
DAY.

TUESDAY AND WEDNESDAY...
DIFFERENCES EXIST BETWEEN GFS AND ECMWF REGARDING TIMING AND
SOUTHERN EXTENT OF MID LEVEL TROF MOVING ACROSS NEW ENG. WE
LEANED TOWARD SLOWER AND FURTHER N ECMWF SOLUTION WHICH BRINGS
FROPA THROUGH REGION TUESDAY WITH CHC SHOWERS FOLLOWED BY DRIER
WEATHER WEDNESDAY. COOLER TEMPS TUE/WED BUT STILL AT OR ABOVE
SEASONABLE NORMALS.
