AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
328 AM EDT MON APR 13 2009

.SYNOPSIS...
HIGH PRESSURE WILL RESULT IN GENERALLY DRY AND SEASONABLE SPRINGLIKE
WEATHER THROUGH THE WEEKEND.  EASTERLY WINDS WILL MAKE IT COOLER
ALONG THE COAST WEDNESDAY/THURSDAY...BUT FRIDAY/SATURDAY SHOULD BE
MILDER.  THE ONE FLY IN THE OINTMENT IS LOW PRESSURE MOVING OFF THE
MID ATLANTIC ON WEDNESDAY...BUT THIS WILL LIKELY PASS TOO FAR SOUTH
TO HAVE MUCH OF AN IMPACT.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
AFTER A VERY COLD START THIS MORNING...THE STRONG MID APRIL SUNSHINE
AND A WELL MIXED ATMOSPHERE ON NORTHWEST FLOW SHOULD ALLOW FOR SOME
RECOVERY.  TEMPERATURES WILL STILL BE BELOW NORMAL FOR THIS TIME OF
YEAR...BUT NOT AS COLD AS YESTERDAY.  EXPECT HIGHS TO RECOVER INTO
THE 50 TO 55 DEGREE RANGE ACROSS MOST LOCATIONS.
HOWEVER...EXCELLENT MIXING WILL STILL SUPPORT WIND GUSTS AROUND 30
MPH THAT WILL MAKE IT FEEL CHILLIER.  WE ALSO ARE EXPECTING SUNNY
SKIES...AS DRY SOUNDINGS SUPPORT VERY LITTLE IF ANY DIURNAL CUMULUS
CLOUDS.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/...

TONIGHT...
MOSTLY CLEAR TO PARTLY CLOUDY SKIES EXPECTED TONIGHT...ALTHOUGH SOME
HIGH CLOUDS MAY AFFECT THE REGION AT TIMES ESPECIALLY ACROSS THE
SOUTHWEST SECTIONS OF OUR REGION.  NONETHELESS...LIGHT WINDS AND A
DRY ATMOSPHERE SHOULD RESULT IN A GOOD NIGHT OF RADIATIONAL
COOLING.  LOWS MAY FALL INTO THE UPPER TEENS ACROSS THE COLDEST
OUTLYING LOCATIONS OF SOUTHWEST NH/NORTHWEST MA...TO MAINLY THE 20S
AND LOWER 30S ELSEWHERE.  THE URBAN HEAT ISLAND OF BOSTON WILL BE
THE WARMSPOT WITH OVERNIGHT LOWS EXPECTED IN THE MID TO UPPER 30S.

TUESDAY...
PARTLY TO MOSTLY SUNNY SKIES...LIGHT WINDS AND A DRY ATMOSPHERE WILL
YIELD A QUICK RECOVERY IN TEMPERATURES JUST INLAND FROM THE
IMMEDIATE COAST.  HIGHS SHOULD RECOVER INTO THE UPPER 50S...TO NEAR
60 AND WITH LIGHT WINDS IT WILL FEEL QUITE COMFORTABLE OUTSIDE.
ALONG THE IMMEDIATE COAST...TEMPERATURES WILL BE QUITE TRICKY.
HIGHS MAY COME UP QUICKLY UNTIL LATE MORNING...THEN SEA BREEZES
SHOULD KICK IN AND TEMPERATURES WILL LIKELY FALL BY MID OR LATE
AFTERNOON.  FOR NOW WILL RUN WITH HIGHS BETWEEN 50 AND 55...AND THEN
SHOW THEM FALLING BELOW 50 ALONG THE COAST BY LATE AFTERNOON.  LATER
SHIFTS MAY HAVE TO REFINE THIS A BIT BASED ON NEW GUIDANCE.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...

TUESDAY NIGHT AND WEDNESDAY...CLOSE CALL WITH A DEVELOPING COASTAL
LOW TRACKING OFF THE MID ATLANTIC COAST. CONFLUENT FLOW ALOFT SHOULD
SUPPRESS MUCH OF THE LOWS PRECIPITATION SHIELD SOUTH OF THE AREA.
HOWEVER CONTINUING TO NOTE SOME INCREASING MID LEVEL FRONTOGENESIS
ADVERTISED WELL NORTH OF THE DEVELOPING LOW. RH FIELDS ARE EXPECTED
TO MOISTEN UP FROM H7 AND ALOFT AND IN THE BOUNDARY LAYER WITH
EXPECTED NE FLOW ALONG THE COAST. HOWEVER RH LEVELS AT H85 REMAIN
LOW AT LEAST INITIALLY AND BEST MECHANISMS FOR ISENTROPIC LIFT
ARE EXPECTED TO REMAIN WELL S OF THE FORECAST AREA. SO OVERALL
INCREASING CLOUDS CAN BE EXPECTED SOUTH OF THE MASS PIKE. ADDED A
LOW CHANCE POP IN CONNECTICUT....RHODE ISLAND AND SOUTH COASTAL
MASSACHUSETTS TUESDAY NIGHT INTO WEDNESDAY. TEMPERATURES WILL REMAIN
COOL.

THURSDAY...DEVELOPING LOW PRESSURE PASSES OFFSHORE WITH CONTINUED
BRISK ONSHORE FLOW ALONG THE COAST AND SEASONABLY MILD AND DRY
CONDITIONS INLAND.

FRIDAY THROUGH SUNDAY...A WARMUP IS ANTICIPATED FRIDAY BEFORE A COLD
FRONT CROSSES THE AREA SOMETIME SATURDAY MORNING. THERE COULD BE A
SPRINKLE WITH THE ASSOCIATED FRONTAL PASSAGE...THE FRONT CURRENTLY
APPEARS MOISTURE STARVED...SO FOR NOW HAVE JUST ADVERTISED A PARTLY
CLOUDY FORECAST. GENERALLY FAVORED THE MORE AMPLIFIED ECMWF SOLUTION
OVER THE MORE PROGRESSIVE GFS FROM DAYS 5 THROUGH 7. CYCLONIC FLOW
SHOULD BRING MORE CLOUDS AND SOMEWHAT COOLER TEMPS ON SATURDAY. THE
REMAINDER OF THE WEEKEND APPEARS DRY WITH NEAR SEASONABLE TEMPERATURES.

FREQUENT WIND GUSTS OF 25 TO 30 MPH AND MINIMUM AFTERNOON RELATIVE

HUMIDITIES AND GUSTY NORTHWEST WINDS WILL NOT ISSUE ANY FIRE WEATHER
