AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
1002 PM EDT TUE MAR 31 2015

.SYNOPSIS...
LIKELY RAIN/SNOW SLIDES ACROSS SOUTHERN PORTIONS OF CONNECTICUT...
RHODE ISLAND AND MASSACHUSETTS OVERNIGHT WITH LITTLE IMPACT. HIGH
PRESSURE YIELDS CHILLY BUT DRY WEATHER WEDNESDAY. WARMER THURSDAY
AND ESPECIALLY FRI AHEAD OF A COLD FRONT. LOW PRESSURE DEVELOPS ON
THE FRONT FRIDAY NIGHT AND MOVES ACROSS THE REGION EARLY SATURDAY
BRINGING LOCALLY HEAVY RAIN SHOWERS. MAINLY DRY AND MUCH COLDER
LATER SATURDAY AND SUNDAY. HIGH UNCERTAINTY NEXT WEEK WITH PERIODS
OF UNSETTLED WEATHER POSSIBLE.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
10 PM UPDATE...
LATEST MESOSCALE GUIDANCE...PARTICULARLY THE WRF CONTINUES TO
OUTPERFORM REMAINING GUIDANCE REGARDING THE PRECIP SHIELD AND
DEEPENING LOW PRES MOVING OFFSHORE. IT APPEARS THAT SOME
CONVECTION IS LIKELY TO USURP MOISTURE/LIFT AS THE LOW PRES
CONTINUES TO DEEPEN FURTHER OFFSHORE. THIS TIGHTENS THE PRECIP
GRADIENT AND ALLOWS DRIER AIR TO MORE QUICKLY ENTRAIN FROM THE N.
THEREFORE...WHAT FALLS THROUGH MIDNIGHT WILL LIKELY BE ALL THAT WE
WILL SEE WITH THE ONE EXCEPTION BEING NANTUCKET...WHICH IS CLOSER
TO THE LOW CENTER.

PREVIOUS DISCUSSION...

*/OVERVIEW ...

EVEN WITH THE 31.12Z FORECAST GUIDANCE...CONSENSUS HAS THE CLIPPER-
LOW SWEEPING S OF NEW ENGLAND OFF THE DELMARVA COASTLINE ACROSS
REGIONS OF BETTER BAROCLINICITY OFFSHORE. EXPECT A SHARP GRADIENT
WITH RESPECT TO OUTCOMES AROUND THE CT-RI-MA BORDER DUE TO A
COMBINATION OF THE FOLLOWING: 1) DECENT MOISTURE AND LIFT UP TO H5
WITH SYNOPTIC QG-FORCING / OMEGA ABOVE ... 2) A LOCALIZED GREATER
FOCUS ALONG A PARENT H6-8 WARM FRONT ASSOCIATED WITH THE CLIPPER
LOW AS W-E ZONAL MOIST FLOW IS SQUEEZED UP AGAINST A COLDER AND
DRIER AIRMASS ASSOCIATED WITH HIGH PRESSURE BUILDING OUT OF THE
NW.

OUTCOMES COULD STILL WOBBLE SLIGHTLY N OR S. BUT TRUST THE NEAR-
TERM MESOSCALE GUIDANCE TO BE NEARLY SPOT ON. WHILE IT APPEARS THE
STRATIFORM-SHIELD PER WSR-88D RADAR RETURNS TO THE W WILL ENVELOPE
MUCH OF S NEW ENGLAND...EROSION IS EXPECTED ALONG THE N PERIPHERY
OF RETURNS /ALREADY BEING OBSERVED/ AS THE CLIPPER-LOW EMERGES
OFF THE DELMARVA COAST INVOKING AN ISALLOBARIC RESPONSE TO THE
WIND AND THE SUBSEQUENT ADVECTION OF COLDER AND DRIER AIR WITHIN
THE LOW-LEVELS S ACROSS THE REGION.

AGAIN...THE BATTLE LINE BETWEEN AIRMASSES AND WHERE THE BETTER
AFOREMENTIONED LOW- TO MID-LEVEL BANDING ORIGINATES LOOKS TO BE AT
OR S OF THE CT-RI-MA BORDER. WILL CONTINUE WITH HIGH CATEGORICAL
POPS S OF THE BORDER...ESP ALONG THE S-COAST AND POINTS OFFSHORE.

*/ TOWARDS EVENING ...

WITH ONLY LIGHT PRECIPITATION AT ONSET EXPECTED AND NOTING HOW
TEMPERATURES TODAY WARMED TO THE 50-DEGREE MARK UNDER ABUNDANT
SUNSHINE...IT WILL LIKELY TAKE LONGER FOR THE DRY LOW-LEVELS PER
12Z CHATHAM / UPTON SOUNDINGS TO DYNAMICALLY COOL AT THE SURFACE
TO TEMPERATURES BELOW FREEZING. WITH A WARM BOUNDARY-LAYER...AM
EXPECTING MUCH OF THE PRECIPITATION TO BE IN THE FORM OF RAIN WITH
PERHAPS A WET-SNOWFLAKE MIXED IN. LITTLE TO NO IMPACT EXPECTED.

*/ EVENING AND TOWARDS MIDNIGHT ...

BOTH NOCTURNAL COOLING AND AN INCREASING INTENSITY OF PRECIP IS
LIKELY TO RESULT IN RAIN MIXING WITH AND / OR CHANGING OVER TO
SNOW. TEMPS AROUND THE FREEZING MARK DURING THIS PERIOD...SNOW
ACCUMULATION WILL LIKELY BE HARD TO COME BY...NO MORE THAN A
COATING IF ANYTHING ON ELEVATED EXPOSED SURFACES. WET ROADWAYS
LIKELY FOR THE MOST PART. BIGGEST IMPACT LIKELY IN THE FORM OF
REDUCED VISIBILITIES AND ESPECIALLY MORE SO ALONG THE S-COASTLINE
OF NEW ENGLAND.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
*/ WEDNESDAY...

COLD AIRMASS ALOFT IN WAKE OF THE CLIPPER-LOW. H85 TEMPS RANGING
AROUND -4 TO -6C UP TO WHICH THE BOUNDARY-LAYER WILL MIX-DOWN DRIER
AIR AND FASTER MOMENTUM. ANTICIPATING MOSTLY CLEAR CONDITIONS WITH
BREEZY W-WINDS AS HIGHS TOP INTO THE LOW- TO MID-40S.

*/ WEDNESDAY NIGHT...

MOSTLY CLEAR CONDITIONS PERSISTING PRIOR TO MORNING BY WHICH POINT
THE LOW- TO MID-LEVEL RIDGE SWEEPS ACROSS THE REGION ALONG THE W-
PERIPHERY OF WHICH IS THE CONVERGENT NOSE OF WARM-MOIST SW-FLOW
UNDERGOING ISENTROPIC LIFT YIELDING MID- TO HIGH-LEVEL CLOUDS. FEEL
THE MAJORITY OF THE OVERNIGHT PERIOD WILL BE CHARACTERIZED BY DRY
WEATHER AND LIGHT AND VARIABLE FLOW ALLOWING A PERIOD OF GOOD
RADIATIONAL COOLING. LOWS DROPPING INTO THE 20S FOR MOST LOCATIONS.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
HIGHLIGHTS...

* TEMPERATURES RISING TO NEAR NORMAL THU AND ABOVE NORMAL FRI
* STORM SYSTEM BRINGS SHOWERS THU NIGHT INTO EARLY SAT
* BLUSTERY AND COLDER LATE SAT INTO SUN

OVERVIEW...

NORTHERN STREAM REMAINS AMPLIFIED BY EARLY APRIL STANDARDS FOR LATER
THIS WEEK AND WEEKEND. THIS RESULTS IN LARGE TEMP SWINGS FOR OUR
AREA ALONG WITH A ROUND OF SHOWERS.

LATE SUNDAY INTO EARLY NEXT WEEK UNCERTAINTY IS HIGH AS ENSEMBLE AND
DETERMINISTIC GUIDANCE ARE AT ODDS WITH EACH OTHER.  THE GEFS AND
EPS ENSEMBLES SUGGEST THE UPPER AIR PATTERN DEAMPLIFIES WITH MORE OF
A PACIFIC REGIME FLOODING THE CONUS AND SIGNS OF A SUBTROPICAL RIDGE
BUILDING OVER THE SOUTHEAST STATES. THIS WOULD FAVOR MORE SEASONABLE
TEMPS FOR SOUTHERN NEW ENGLAND NEXT WEEK. HOWEVER THE DETERMINISTIC
GUIDANCE SUGGEST THE HUDSON BAY VORTEX WILL BE SLOWER TO
DEPART...KEEPING REMNANT COLD AIR LONGER ACROSS SOUTHEAST QUEBEC
INTO NEW ENGLAND. THUS POTENTIAL UNSETTLED WEATHER PATTERN AT LEAST
EARLY NEXT WEEK AS PACIFIC MOISTURE STREAMS ACROSS THE NORTHERN
STATES AND POTENTIAL INTERACTS WITH REMNANT COLD AIR OVER NEW
ENGLAND.

DAILY SENSIBLE WEATHER...

THURSDAY...LOW RISK FOR A PERIOD OF MAINLY LIGHT RAIN IN THE MORNING
AND POSSIBLY EARLY AFTERNOON AS WARM FRONT ALOFT PASSES ACROSS THE
REGION. CLEARING DURING THE AFTERNOON. THE TRUE WARM SECTOR AIRMASS
DOESN/T ARRIVE UNTIL SOMETIME FRI MORNING BUT TEMPS THU AFTERNOON
SHOULD AT LEAST TOUCH 50 AWAY FROM THE SOUTH COAST GIVEN AFTERNOON
SUNSHINE. IT WILL ALSO BECOME WINDY AS LOW LEVEL JET CRANKS UP TO
ABOUT 55-65 KT BY 00Z AT 925 MB. NOT EXPECTING ALL OF THIS WIND TO
MIX DOWN BUT NAM BUFKIT SOUNDINGS SUPPORT SSW WINDS GUSTING UP TO 35
MPH OR SO LATE IN THE DAY.

THU NIGHT...LOW RISK OF A FEW ELEVATED TSTMS AS MID LEVEL LAPSE
RATES STEEPEN TO ABOUT 7C/KM ALONG WITH WEAK MOIST CYCLONIC FLOW
ALOFT. COULD SEE A FEW DOWNPOURS AS INSTABILITY WORKS WITH PWATS OF
TO +2 STD ABOVE CLIMO

FRI...FRONT STALLS OVER OR NORTH OF THE REGION AS WEST TO EAST MID
LEVEL FLOW PARALLELS THE FRONT. MILD WITH WARM SECTOR REMAINING
ACROSS MUCH OF THE REGION ESP CT/RI AND SOUTH OF THE MASS PIKE. ALL
GUID SOURCES INCLUDING A MODEL BLEND HAVE TEMPS IN THE U50S AND
L60S. DESPITE THE RISK OF SHOWERS IT WILL FEEL MILD/WARM AS DEW PTS
CLIMB INTO THE L50S. THIS WILL PROMOTE CONDENSATION AND HELP ERODE
REMAINING SNOWPACK. AS FOR COVERAGE OF SHOWERS DIFFICULT TO SAY AT
THIS TIME RANGE HOW WIDESPREAD GIVEN MODELS DISAGREE ON HOW WAVY THE
FRONT WILL BE. THUS FOR NOW WILL KEEP SHOWERS SCATTERED WITH POPS 30-
50%.

FRI NIGHT INTO SAT...GOOD MULTI MODEL AGREEMENT ON FRONTAL WAVE
BEING AN INSIDE RUNNER OR TRACKING OVER SOUTHERN NEW ENGLAND. THIS
WILL LIKELY TRANSLATE TO HEAVIEST SHOWERS AND FRONTAL CONVERGENCE
OVER THE INTERIOR INTO CENTRAL/NORTHERN NEW ENGLAND. FAIRLY STRONG
JET DYNAMICS /WIND FIELDS +1 TO +2 STD ABOVE NORMAL/ COUPLED WITH
PWATS +2 STD ABOVE CLIMO SUGGEST AT LEAST A MODEST SLUG OF QPF. BIG
DISCREPANCY REGARDING EVOLUTION OF FRONTAL WAVE AS GFS IS MOST
ROBUST WITH 979 MB LOW OVER MAINE 18Z SAT. GFS WOULD SUGGEST STRONG
WINDS. MEANWHILE THE EC /985 MB/ AND UKMET /988 MB/ ARE SLIGHTLY
WEAKER. SO FOR NOW LOOKS WINDY SAT BUT WILL HAVE TO WATCH LATER
MODEL TRENDS FOR POSSIBLY STRONGER/DAMAGING WINDS IN COLD ADVECTION
REGIME.

SUNDAY...HIGH UNCERTAINTY GIVEN TIME RANGE AND FAST FLOW ALOFT.
SHOULD BE DRY AND COOL TO START THE DAY BUT PACIFIC MOISTURE QUICKLY
STREAMING IN FROM THE WEST LATE IN THE DAY OR AT NIGHT. THUS LOW
RISK FOR A PERIOD OF RAIN/SNOW PENDING THERMAL PROFILES.

NEXT WEEK...LOTS OF UNCERTAINTY AS MENTIONED ABOVE. LOOKS UNSETTLED
WITH PACIFIC MOISTURE ENTERING THE NORTHEAST ALONG WITH POTENTIAL
PTYPE ISSUES AS REMNANT COLD AIR LINGERS OVER QUEBEC INTO NEW
ENGLAND.
