  TRAVEL TONIGHT AND WILL STILL BE FALLING HEAVILY DURING THE
  START OF THE MONDAY MORNING RUSH HOUR ACROSS THE UPPER

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
240 PM EDT FRI MAR 18 2016

.SYNOPSIS...
A VIGOROUS POLAR FRONT WILL SWEEP THROUGH THE AREA TODAY
BRINGING SCATTERED SHOWERS...SOME OF WHICH MAY ALSO PRODUCE SMALL
HAIL AND GUSTY WINDS. THIS FRONT WILL USHER MUCH COLDER WEATHER
INTO THE REGION FOR THE WEEKEND. A SIGNIFICANT WINTER STORM
APPEARS LIKELY FOR PORTIONS OF SOUTHERN NEW ENGLAND SUNDAY
AFTERNOON INTO MONDAY MORNING...BUT THE LOCATION FOR THE POTENTIAL
SIGNIFICANT SNOW REMAINS UNCERTAIN.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

215 PM UPDATE...

BANDS OF SHOWERS REMAINING MAINLY ACROSS THE CT VALLEY INTO NE
CT...WITH A FEW MORE SPOTTY SHOWERS SEEN ACROSS N CENTRAL MA AND N
RI AT 18Z AS SEEN ON LATEST NE REGIONAL 88D RADAR. NO LIGHTNING
SEEN YET...BUT HAVE RECEIVED A COUPLE OF REPORTS OF SMALL GRAUPEL
SINCE 1 PM...BOTH IN N CENTRAL CT /TOLLAND AND STORRS/. NOTED TWO
RATHER STRONG RADAR RETURNS ASSOCIATED WITH THESE REPORTS.

AS COLD FRONT MOVES ACROSS THE REGION THROUGH THE REMAINDER OF THE
AFTERNOON...WILL CONTINUE TO SEE SCATTERED SHOWERS MOVE THROUGH.
W-NW WINDS CONTINUE TO GUST UP TO 25-30 KT...WITH REPORTS OF 33 KT
AT KBAF AND KORH...UP TO 34 KT AT KBDL SINCE 16Z. WITH THE
EXCELLENT LOW LEVEL MIXING CONTINUING...GUSTS TO AROUND 30 KT WILL
CONTINUE THROUGH LATE THIS AFTERNOON THEN WILL SLOWLY DIMINISH.

SKIES WERE MAINLY CLOUDY AT 18Z WITH SOME BREAKS IN THE CLOUDS.
WILL SEE THESE START TO DISSIPATE AFTER 22Z AS BEST DIURNAL
HEATING ENDS.

TEMPS RUNNING FROM 45-50 ACROSS MOST AREAS...THROUGH HAVE REACHED
INTO THE LOWER 50S ACROSS E MA.

UPDATED CLOUD COVER...TEMPS AND DEWPTS FOR THE REMAINDER OF THE
AFTERNOON TO BRING NEAR TERM CONDITIONS CURRENT.

PREVIOUS DISCUSSION...

12Z KCHH SOUNDING SHOWING W-NW WIND UP TO 43 KT AT 1700 FT AND 39
KT AT AROUND 4000 FT...WITH KALY WINDS AT 39 KT/1700 FT AND 33
KT/2700 FT. EXCELLENT MIXING REMAINS IN PLACE WITH INVERTED
SOUNDINGS. NOTING FREEZING LEVEL DOWN TO 2200 FT ON 12Z KALY
SOUNDING.

NOTING SHOWERS BEGINNING TO FORM ACROSS THE E SLOPES OF THE
BERKSHIRES PUSHING E-SE INTO THE CT VALLEY. WILL CONTINUE TO SEE
SHOWERS DEVELOPING AS COLD POOL CONTINUES TO SINK ACROSS THE
REGION THIS AFTERNOON. NOT SURE HOW MUCH WILL REACH THE GROUND AS
TEMP/DEWPT SPREADS ON ORDER OF 12-20 DEGREES ACROSS CENTRAL AND
WESTERN AREAS.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/...
TONIGHT...
SHOWERS COME TO AN END THIS EVENING WITH LOSS OF DIURNAL HEAT
SUPPORT AND COLD FRONT SHIFTING OFFSHORE. THE CONTINUED COLD
ADVECTION ALOFT AND SOME NW FLOW WILL YIELD LOW MINS
OVERNIGHT...MAINLY IN THE 20S. SLIGHT NW BREEZES /ALTHOUGH
BECOMING LIGHTER/ WILL LEAD TO COLD WIND CHILLS MAINLY IN THE
TEENS AND SINGLE DIGITS. CLOUDS GRADUALLY CLEAR THROUGH THE NIGHT.

SAT...
MAINLY SUNNY SKIES ALTHOUGH SOME HIGH CLOUDS MAY BUILD OVER THE
SRN TIER IN ADVANCE OF THE STORM SYSTEM WE ARE WATCHING FOR
SUN/MON. HOWEVER...H92 TEMPS DROP AS LOW AS -5C BY LATE DAY...SO
EVEN WITH THIS SUNSHINE TEMPS WILL ONLY STRUGGLE INTO THE LOW
40S...OR JUST BELOW SEASONAL NORMALS. DRY CONDITIONS AS DWPTS DROP
INTO THE SINGLE DIGITS.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
HIGHLIGHTS FOR LATE SEASON WINTER STORM POTENTIAL SUN PM/MON AM:

* SIGNIFICANT WINTER STORM STILL POSS FOR AT LEAST PART OF THE REGION
* LOW CONFIDENCE ON BEST CHANCE FOR SIGNIFICANT SNOWFALL
* WESTERN TRACK: SIGNIFICANT SNOW POTENTIAL ACROSS INTERIOR WITH DRY
  SLOT/PTYPE ISSUES ON THE COASTAL PLAIN
* EASTERN TRACK: LIGHTER SNOWFALL ACROSS THE INTERIOR WHILE
  SIGNIFICANT SNOW POTENTIAL OCCURS ACROSS EASTERN MA/RI

DETAILS...

SUNDAY INTO MONDAY....

A FAIRLY COLD AIRMASS WILL BE IN PLACE FOR LATE MARCH EARLY SUNDAY
MORNING WITH HIGH PRESSURE ACROSS EASTERN CANADA.  AT THE SAME
TIME...A POTENT CLOSED UPPER LEVEL DISTURBANCE WILL BE APPROACHING
FROM THE WEST AND INTERACT WITH NORTHERN STREAM ENERGY.  THE
STRENGTH AND TIMING OF THE ENERGY WILL DETERMINE THE STRENGTH/TRACK
OF THE STORM AND WHERE HEAVIEST SNOWFALL OCCURS.

NORMALLY AS YOU GET CLOSER TO AN EVENT CONFIDENCE IN A GIVEN
SCENARIO INCREASES...BUT THE OVERNIGHT MODEL RUNS ACTUALLY DID THE
OPPOSITE.  NOW THAT DOES OCCASIONALLY HAPPEN...PARTICULARLY WHEN THE
MAIN EVENT IS STILL OUTSIDE 72 HOURS IN THE MODEL WORLD.

TO SUMMARIZE...THE EARLIER 12Z INTERNATIONAL MODELS SHOWED A RAPIDLY
INTENSIFYING LOW PRESSURE SYSTEM PASSING NEAR THE CAPE/ISLANDS. THIS
SCENARIO WOULD BRING A LARGE SWATH OF 6 TO 12+ INCHES OF SNOW ACROSS
INTERIOR MA AND NORTHERN CT WITH THE HELP OF A POTENT BACK BENT
MID LEVEL WARM FRONT....WHILE MUCH OF EASTERN MA/RI WOULD RECEIVE
A FRONT END THUMP OF HEAVY SNOW AND THEN HAVE DRY SLOT/PTYPE
ISSUES. STRONG WIND GUSTS OF 40 TO 55 MPH WILL ALSO BE A CONCERN
FOR A TIME ALONG THE COAST. MEANWHILE...THE 12Z AMERICAN MODELS
SHOWED A WEAKER AND MORE PROGRESSIVE LOW PRESSURE SYSTEM CONFINING
MOST OF THE SIGNIFICANT SNOW TO EASTERN MA/RI WITH LIGHTER SNOWS
BACK INTO THE INTERIOR.

AT 00Z...THE NAM JOINED THE 12Z INTERNATIONAL MODELS SHOWING A
POTENT SETUP FOR HEAVY SNOW ACROSS THE INTERIOR WITH A FRONT END
THUMP FOLLOWED BY DRYSLOT/PTYPE ISSUES ON THE COASTAL PLAIN.
HOWEVER...THE LATEST 00Z OPERATIONAL ECMWF WHICH HAD BEEN CONSISTENT
TRENDED SIGNIFICANTLY FURTHER EAST AND WEAKER.  THIS WOULD CONFINE
SIGNIFICANT SNOW POTENTIAL TO EASTERN MA/RI WITH A LIGHTER SNOWFALL
BACK INTO THE INTERIOR. THE ECMWF ENSEMBLES ALSO TRENDED FURTHER
EAST...BUT THERE WAS STILL A LARGE SPREAD WITH SOME STILL SHOWING
BIG HITS ACROSS THE INTERIOR...BUT MORE ACROSS EASTERN NEW ENGLAND.
AS FOR THE GFS...IT REMAINED THE WEAKEST AND FURTHEST EAST SOLUTION
BUT ITS INDIVIDUAL ENSEMBLE MEMBERS STILL SHOWED A LARGE POTENTIAL
RANGE IN POSSIBLE OUTCOMES.

SO IN A NUTSHELL...A SIGNIFICANT WINTER STORM IS STILL POSSIBLE FOR
AT LEAST A PORTION OF SOUTHERN NEW ENGLAND.  THE MAIN QUESTION IS
WHERE DOES THIS OCCUR.  A LOT OF THE 00Z GUIDANCE...BUT CERTAINLY
NOT ALL OF IT SHIFTED THE POTENTIAL OF HEAVIEST SNOW ACROSS EASTERN
MA/RI. HOWEVER...THE INTERIOR BY NO MEANS IS OUT OF THE WOODS AS
SOME OF THE GUIDANCE STILL HAS THE FOCUS OUT IN THAT REGION.  THE
SPREAD IN THE ENSEMBLES AND SUBTLE TIMING DIFFERENCES IN SHORTWAVE
INTERACTION TELL US ITS TOO EARLY TO LOCK IN A SPECIFIC SCENARIO.

SNOWFALL FORECAST...

IN COORDINATION WITH OUR SURROUNDING OFFICES WE WENT AHEAD AND
ISSUED A SNOWFALL FORECAST THROUGH 12Z MONDAY. AT THIS TIME RANGE
THE REASONABLE WORST/BEST CASE SCENARIOS HAVE MORE USE THAN THE
DETERMINISTIC MAP AND IT SHOWS THE TREMENDOUS UNCERTAINTY THAT
EXISTS. SINCE THE EVENT WILL OCCUR LATE IN THE 5TH/6TH PERIOD IT
