AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
254 PM EDT FRI APR 24 2015

.SYNOPSIS...
UNSEASONABLY COOL WEATHER CONTINUES THROUGH THIS WEEKEND WITH
SPOTTY SHOWERS OR SPRINKLES. UNSETTLED WEATHER AND BELOW NORMAL
TEMPERATURES WILL CONTINUE THROUGH NEXT WEEK AS WELL.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
THROUGH 8 PM...
UPPER LOW AND COLD POOL IN PLACE OVER NEW NEW ENGLAND. A WEAK
SHORTWAVE MOVES THROUGH THE CYCLONIC FLOW AROUND THIS LOW AND
CROSSES NEW ENGLAND TOWARD 00Z. RH FORECAST PROFILES SHOW A LAYER
OF HIGH RH VALUES BETWEEN 850 AND 700 MB THROUGH 00Z...ALTHOUGH
VERTICAL MOTION IS SUBSIDENT. WE COULD SEE A FEW SPRINKLES OR
FLURRIES LATE TODAY/THIS EVENING.

TONIGHT...LINGERING CLOUD SHIELD UNDER THE UPPER LOW AND COLD
POOL...BUT THIS SHOULD START TO LIFT OUT TO THE NORTH AND EAST
SOMEWHAT. SO WE EXPECT AT LEAST PARTIAL CLEARING TONIGHT WITH THE
BEST CHANCE OVER CONNECTICUT. PRESSURE GRADIENT STAYS ENOUGH TO
KEEP THE AIR MOVING...SO FROST IS NOT LIKELY EXCEPT POSSIBLY IN
THE MOST SHELTERED OF LOCATIONS THAT CLEAR. ON THE OTHER HAND
TEMPERATURES WILL BE SIMILAR TO LAST NIGHT OR PERHAPS A DEGREE OR
TWO COOLER. EXPECTED RANGE IS IN THE UPPER 20S AND 30S...AND
FREEZING TEMPS IN PARTS OF THE ACTIVE GROWING ZONE /CT-RI-
SOUTHEAST MA/. WE PLAN ON CONVERTING THE EXISTING FREEZE WATCH TO
A FREEZE WARNING FOR NORTHERN CT AND NORTHWEST RI.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/...
SATURDAY...UPPER CLOUD SHIELD AND COLD POOL WILL BE FOCUSSED OVER
NORTHERN NEW ENGLAND BUT CLOSE ENOUGH TO AFFECT US. DAYTIME
HEATING AND A SHORTWAVE CYCLING AROUND THE LOW MAY PUSH CLOUDS
BACK OUR WAY DURING THE DAY. THE SURFACE LAYER WILL BE DRIER...SO
MOST ATTEMPTS AT PRECIPITATION SHOULD EVAPORATE ON THE WAY DOWN.
TEMPS AT 850 MB ARE FORECAST AROUND -2C...WHICH SUPPORTS MAX SFC
TEMPS IN THE 50S. WINDS ALOFT IN THE MIXED LAYER REACH 20
KNOTS...SO EXPECT ANOTHER DAY OF GUSTS EITHER SIDE OF 20.

SATURDAY NIGHT...

WEAK RIDGE BUILDS OVER SOUTHERN NEW ENGLAND PROVIDING CLEARING
SKIES AND LIGHT WINDS. RADIATIONAL COOLING WITH DEW POINTS IN THE
30S...SO MIN SFC TEMPS SHOULD BE IN THE 30S.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
HIGHLIGHTS...

* BELOW NORMAL TEMPERATURES THROUGH NEXT WEEK
* SCATTERED DIURNAL SHOWERS THIS WEEKEND INTO MID-NEXT WEEK
* LOW CONFIDENCE ON COASTAL SYSTEM THURS/FRIDAY.

OVERVIEW...

DEEP CLOSED LOW OVER THE REGION BEGINS TO GRADUALLY PIVOT EAST
OFFSHORE NOVA SCOTIA ON SAT BUT THEN BECOMES NOTABLY ELONGATED BY
SUN AS ADDITIONAL ENERGY DROPS SOUTH DOWN ACROSS THE NORTHEAST. THE
00Z GEM IS THE WEAKEST SOLUTION WHILE THE 00Z GFS/00Z NAM/00Z UKMET
AND 00Z ECMWF ARE ALL BETTER CLUSTERED WITH DEPTH AND TIMING THROUGH
SUNDAY.

BY NEXT WEEK APPEARS UNSETTLED WEATHER AND BELOW NORMAL TEMPS
CONTINUE AS BLOCKING PATTERN PERSIST...SUPPORTED BY -NAO/-AO/+PNA.
UPPER LEVEL LOW AND CONTINUED COLD POOL WILL KEEP ON SPINNING OVER
THE REGION MONDAY AND BEGIN TO EXIT LATE TUESDAY. STILL LOTS OF
QUESTIONS ABOUT THE MIGRATION OF THE DESERT CUTOFF LOW AS IT MOVES
ACROSS THE SOUTHEAST AND ITS POTENTIAL WRAP UP INTO ANOTHER CLOSED
LOW FOR NEW ENGLAND. A KEY COMPONENT OF THE SYSTEM'S INTENSIFICATION
WILL BE THE INCORPORATION OF SOUTHEASTWARD-MOVING SHORTWAVE ENERGY
AND WHERE THIS NORTHERN STREAM ENERGY WILL PHASE WITH THE CUTOFF
SYSTEM. CURRENTLY THE 00Z GFS PHASES THE SOUTHERN PLAIN WAVE FASTER
THAN THE EC WHICH IS MORE AMPLIFIED. THE EC/S NORTHERN STREAM IS
FARTHER EASTWARD THAN THE GFS...IN WHICH THE EC SEEMS TO PULL A
COASTAL LOW CLOSER TO THE REGION BY THUS/FRI. REGARDLESS APPEARS
THAT A COASTAL LOW WILL HAVE AN IMPACT ON THE REGION LATE IN THE
WORK WEEK. FELT ENSEMBLE GUIDANCE WAS BEST FOR THE WORK WEEK.

DETAILS...

* SUNDAY...HIGH CONFIDENCE.

STRONG CUTOFF LOW WILL CONTINUE TO IMPACT THE NORTHEAST DURING THIS
TIME PERIOD. UPPER LEVEL RIDGE OVER THE CENTER CONUS WILL BUILD
PUSHING THE BULK OF THE ENERGY OFFSHORE SAT NIGHT BEFORE THE LOW
MIGRATES BACK TOWARDS NEW ENGLAND BY SUNDAY. STRONG SHORTWAVE WILL
MOVE THROUGH THE REGION FROM THE NORTH INCREASING PRECIPITATION
CHANCES ON SUNDAY. TEMPS MAY REACH 60F AS COLD POOL IS STILL
OFFSHORE.

* MONDAY INTO TUESDAY...MODERATE CONFIDENCE.

THE UPPER LEVEL LOW WILL RETROGRADE INCREASING THE CHANCES OF PRECIP
AS 2 POTENT SHORTWAVES MORE THROUGH THE FLOW FROM THE NORTH. COLD
POOL ALOFT SEEMS TO SIT OVER THE REGION AS WELL. CHANCE FOR SHOWERS
WILL BE HIGHER THAN FOR THIS UPCOMING WEEKEND AS LAPSE RATES WILL BE
STEEPER AND SOME HINTS OF INSTABILITY. INCREASED POPS ESP ALONG THE
MASS COASTLINE WHERE FORCING COULD OCCUR IF SEA BREEZE DEVELOPS.
TEMPERATURES APPEAR TO BE AROUND 10 DEGREES COOLER ON MONDAY THANKS
TO THE STRONG COLD POOL OVER THE REGION.

* WEDNESDAY AND BEYOND...LOW CONFIDENCE.

STILL SOME UNCERTAINTY IN THIS PORTION OF THE FORECAST. EVERYTHING
IS DEPENDENT ON HOW THE CUT-OFF LOW IN THE DESERT SOUTHWEST AND
DIGGING NORTHERN STREAM WAVES BEHAVES. CURRENTLY BELIEVE WED IS A
TRANSITION DAY WITH MID LEVEL RIDGE BUILDING INTO THE REGION BUT
KEEPING TEMPS BELOW NORMAL. WATCHING THE DEVELOPMENT OF A COASTAL
LOW ON THURSDAY/FRIDAY. BOTH THE GFS AND EC HAVE SHOWN THE COASTAL
LOW THIS TIME AROUND...SO CONFIDENCE IS INCREASING THAT IT WILL
OCCUR. THIS IS SUPPORTED BY THE ENSEMBLES. THE GFS IS SLIGHTLY
FARTHER OFFSHORE AND FASTER COMPARED TO THE EC...REGARDLESS WET
WEATHER AND COOL TEMPS WILL CONTINUE.
