AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
351 PM EST MON JAN 20 2014

.SYNOPSIS...
AN ARCTIC FRONT SWEEPS ACROSS THE REGION THIS EVENING FOLLOWED BY A
FRIGID AIRMASS OVERSPREADING THE AREA TONIGHT. LOW PRES TRACKS ALONG
THIS FRONT BRINGING WIDESPREAD ACCUMULATING SNOW TO MUCH OF SOUTHERN
NEW ENGLAND. OCEAN EFFECT SNOW SHOWERS WILL LINGERING ACROSS THE
CAPE AND THE ISLANDS ON WEDNESDAY. COLD AND DRY WEATHER IS LIKELY
THURSDAY AND FRIDAY. A POSSIBLE SYSTEM WILL MOVE THROUGH THE
REGION OVER THE WEEKEND BRINGING RAIN/SNOW.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...

4 PM UPDATE...
THE ARCTIC FRONT HAS MADE SLOW PROGRESS SOUTHWARD DURING THE DAY
TODAY. EXPECT THE SPEED OF THE FRONT TO INCREASE AFTER THE SUN
GOES DOWN. SCATTERED SNOW SHOWERS REMAIN POSSIBLE AHEAD OF THE
FRONT.

TONIGHT...
ARCTIC FRONT SWEEPS THROUGH SOUTHERN NEW ENGLAND EARLY THIS
EVENING...PUSHING OFFSHORE BY 10 PM. SOUTHWESTERLY WINDS WILL
SHIFT TO THE NORTHWEST WITH THE FRONT...GUSTING AT TIMES UP TO 25
TO 30 MPH IMMEDIATELY AHEAD OF AND BEHIND THE FRONT. ANY SNOW
SHOWERS THAT DEVELOP AHEAD OF THE FRONT WILL COME TO AN END AS
COLDER... DRIER AIR MOVES IN BEHIND THE FRONT. MUCH COLDER AIR
MOVING IN WILL ALLOW TEMPERATURES TO DROP INTO THE SINGLE DIGITS
TO THE TEENS OVERNIGHT. NORTHWESTERLY WINDS BETWEEN 10 AND 15 MPH
WILL RESULT IN WIND CHILLS IN THE SINGLE DIGITS NEAR ZERO
OVERNIGHT...PARTICULARLY ACROSS THE INTERIOR.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/...

***WIDESPREAD ACCUMULATING SNOW EXPECTED LATE TUESDAY INTO TUESDAY
  NIGHT***

TUESDAY AND TUESDAY NIGHT...THE DAY WILL START OUT QUIET BUT COLD
WITH TEMPERATURES IN THE SINGLE DIGITS TO TEENS.  HOWEVER...
CONDITIONS WILL DETERIORATE THROUGHOUT THE DAY.

LOW PRESSURE DEVELOPS OVER EASTERN KENTUCKY ON THE ARCTIC FRONT LATE
EARLY TUESDAY MORNING. THE 12Z NAM/GFS ARE IN VERY GOOD AGREEMENT ON
THE TRACK AND IMPACT OF THIS SYSTEM.  THE LOW WILL TRACK TO THE
NORTHEAST ALONG THE FRONT...PASSING JUST SOUTHEAST OF THE 40/70
BENCHMARK TUESDAY NIGHT.  THIS TRACK IS FAVORABLE FOR HEAVY SNOW
FALLING ACROSS PORTIONS OF SOUTHERN NEW ENGLAND.

QPF/SNOWFALL:
MODEL QPF INDICATES ANYWHERE FROM A COUPLE OF TENTHS OF AN INCH
OVER THE NORTHWESTERN ZONES TO OVER THREE QUARTERS OF AN INCH ON
THE CAPE AND ISLANDS. GOING WITH A STRICT 10:1 RATIO WOULD RESULT
IN AN INCH OR TWO TO ABOUT EIGHT INCHES OF SNOW. HOWEVER...THERE
ARE A FEW FACTORS THAT INDICATE SNOWFALL AMOUNTS COULD BE HIGHER.
FIRST...THE ARCTIC AIRMASS BUILDING IN BEHIND THIS EVENINGS FRONT
WILL BRING VERY COLD TEMPERATURES. THIS WILL RESULT IN A HIGHER
SNOWFALL TO LIQUID RATIO MORE ON THE ORDER OF 15:1 IF NOT 20:1.
SECOND...SNOW GROWTH...PARTICULARLY ACROSS SOUTHEASTERN
MASSACHUSETTS AND RHODE ISLAND...IS IDEAL. THIRD...WITH
NORTHEASTERLY WINDS OVER THE OCEAN WATERS...EXPECT SOME OCEAN
ENHANCEMENT AND HIGHER SNOWFALL AMOUNTS IN AREAS WHERE THIS
OCCURS. THEREFORE...WE ARE FORECASTING 6-10 INCHES ALONG THE 95
CORRIDOR... AND A FOOT OR POSSIBLY MORE ON THE CAPE AND ISLANDS.
EXPECT 4 TO 8 INCHES FOR THE REMAINDER OF THE AREA...WITH THE
HIGHER END AMOUNTS ADJACENT TO AND NORTH AND WEST OF THE 95
CORRIDOR.

WINDS:
EXPECTING NORTHEASTERLY WINDS SHIFTING TO THE NORTH FOR A TIME
TUESDAY NIGHT. WITH 40 TO 50 KT WINDS THROUGHOUT THE LOWER LEVELS
OF THE ATMOSPHERE...EXPECT 20 TO 30 MPH WINDS ALONG THE EAST
COAST...CAPE...AND ISLANDS WITH GUSTS TO 45 TO 50 MPH. BECAUSE
THESE STRONG WINDS WILL COMBINE WITH THE HEAVIEST SNOW...LIKELY
REDUCING VISIBILITIES SUBSTANTIALLY...HAVE ISSUED A BLIZZARD WATCH
FOR THE CAPE AND ISLANDS AS WELL AS EASTERN AND SOUTHERN PLYMOUTH
COUNTIES.

COLD TEMPERATURES/WIND CHILLS:
LOW TEMPERATURES WILL DROP TO THE SINGLE DIGITS ABOVE AND BELOW
ZERO ACROSS MUCH OF THE REGION AND LOW TEENS FROM THE 95 CORRIDOR
EASTWARD TUESDAY NIGHT. NORTHERLY WINDS GUSTING UP TO 25 MPH
ACROSS THE INTERIOR AND AS MENTIONED ABOVE UP TO 50 MPH ON THE
CAPE AND ISLANDS WILL RESULT IN FRIGID WIND CHILLS. WIND CHILL
VALUES WILL DROP BELOW ZERO ACROSS NEARLY ALL OF SOUTHERN NEW
ENGLAND WITH VALUES DROPPING BELOW 15 BELOW ZERO OUTSIDE 495. WILL
LIKELY NEED A WIND CHILL ADVISORY FOR AT LEAST A PORTION OF THE
REGION. HAVE HELD OFF FOR THIS PACKAGE BASED ON PREFERENCES OF
ADJACENT OFFICES THAT HAVE WIND CHILL HEADLINES FOR TONIGHT AS
WELL AS IT BEING A THIRD PERIOD ADVISORY.

TIDES/COASTAL FLOODING:
ASTRONOMICAL TIDES ARE ON THE LOW SIDE FOR THE NEXT COUPLE OF
DAYS WITH THE HIGH TIDE AT BOSTON JUST UNDER 9.5 FEET. WITH THE
WINDS BLOWING PREDOMINANTLY OUT OF THE NORTH RATHER THAN OUT OF
THE NORTHEAST...NOT EXPECTING COASTAL FLOODING TO BE A PROBLEM
WITH THIS STORM. HOWEVER...IT IS SOMETHING TO KEEP AN EYE
ON...PARTICULARLY FOR NORTH FACING BEACHES.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
* LINGER OCEAN EFFECT SNOW SHOWERS WEDNESDAY
* WELL BELOW AVERAGE TEMPERATURES WEDNESDAY INTO FRIDAY...WIND CHILL
  ADV MAY BE NEEDED.
* ANOTHER SYSTEM APPROACHING THE REGION FOR THE WEEKEND.

MODEL GUIDANCE/CONFIDENCE....
HIGH CONFIDENCE IN ARCTIC AIR BLAST FOR WEDNESDAY INTO FRIDAY.
LOWER CONFIDENCE ON POTENTIAL SYSTEM FOR THE WEEKEND. OVERALL
MODEL GUIDANCE IN IS GOOD AGREEMENT. TRENDED WEDNESDAY FORECAST
TOWARDS THE 12Z GFS/NAM WHICH HAVE A GOOD HANDLE ON THE OCEAN
EFFECT SNOW SHOWERS OVER THE CAPE AND ISLANDS. AFTERWARDS TRENDED
THE LONG RANGE TOWARDS THE GEFS/EC WHICH ARE IN SIMILAR
AGREEMENT...ESP FOR THE WEEKEND SYSTEM.

WEDNESDAY...
STRONG COASTAL LOW WILL BECOME NEGATIVELY TILT BY 12Z WEDNESDAY
AND BEGIN TO HEAD TOWARDS THE GULF OF MAINE BY WEDNESDAY
AFTERNOON. BOTH THE NAM AND GFS CONTINUE TO INDICATE ADDITIONAL
OCEAN EFFECT SNOW SHOWERS ACROSS THE IMMEDIATE EAST COAST AND
ESPECIALLY THE CAPE AND THE ISLANDS FOR WEDNESDAY MORNING INTO THE
AFTERNOON HOURS. MODELS ARE INDICATING THAT CAPE VALUES COULD
REACH BETWEEN 200-300 J/KG ACROSS THE CAPE AND THE ISLANDS WITH A
GOOD NORTHERLY FETCH SLOWLY SWITCHING TO THE NORTHWEST. LAPSE
RATES ARE 8-6 C/KM AND WITH MOISTURE STILL IN THE SNOW GROWTH
REGION...ONE CAN EXPECT AN ADDITIONAL 3 TO 5 INCHES ON WEDNESDAY.

THE OTHER MAIN CONCERN IS THE WIND POTENTIAL. AS THE SYSTEM
CONTINUES TO DEEPEN BY WEDNESDAY MORNING...A GOOD 925 MB JET STREAK
OF 40-50KTS WILL MOVE OVERHEAD THE CAPE AND THE ISLANDS. BECAUSE OF
THE STEEP LAPSE RATES BELIEVE WE WILL TAP INTO THESE HIGHER WINDS
AND WILL SEE GUSTS ABOVE 35KTS FROM PLY TO MVY AND POINTS
EASTWARDS...AT LEAST THAT IS FORECASTERS HIGHEST CONFIDENCE. IN FACT
40 TO 45KTS ARE NOT OUT OF THE QUESTION. THESE STRONG WINDS WILL
RESULT IN SIGNIFICANT BLOWING AND DRIFTING SNOW...ESPECIALLY AS THE
SNOW WILL BE VERY FINE...POWDERY. EXPECT THESE GUSTY WINDS TO SLOWLY
DIMINISH BY LATE WEDNESDAY INTO THURSDAY MORNING.

FINALLY...TEMPERATURES WILL REMAIN WELL BELOW AVERAGE ON WEDNESDAY
ESPECIALLY DUE TO THE ARCTIC FRONT. IF WINDS DIE DOWN BY LATE
WEDNESDAY NIGHT/EARLY THURSDAY MORNING...EXPECT TEMPS TO PLUMMENT
BELOW GUIDANCE BECAUSE OF THE FRESH SNOWPACK ON THE GROUND. HAVE
TRENDED THE FORECAST THIS WAY BY JUST A FEW DEGREES...ESP IN NW
PORTION OF THE REGION. WIND CHILL ADVISORIES MAY NEED TO BE
CONSIDERED.

THURSDAY INTO FRIDAY....
REINFORCING ARCTIC AIR WILL STICK AROUND ON THURSDAY AND FRIDAY.
CONDITIONS WILL BE MAINLY DRY. BECAUSE OF HOW STRONG THE COLD AIR
WILL BE ALOFT AND MOVING OVER THE SOMEWHAT WARMER WATERS...EXPECT
A TEMP DIFFERENCE OF 15C OR MORE FROM THE SURFACE TO 850MB. THIS
INDICATES THAT OCEAN EFFECT SNOW SHOWERS WILL STREAM ACROSS THE
WATERS...ESP IN A WESTERLY FLOW. THIS WILL LAST WELL IN FRIDAY

THE WEEKEND...
STILL A SPREAD IN GUIDANCE WITH A POTENTIAL SYSTEM OVER THE
WEEKEND. THE EC BRINGS IT ON SATURDAY WHICH THE GFS PUSHES IT INTO
SOUTHERN NEW ENGLAND BY SUNDAY. LEANED MORE TOWARDS THE SATURDAY
SOLUTIONS AS WE ARE IN A VERY PROGRESSIVE PATTERN. REGARDLESS
TEMPS WILL WARM SLIGHTLY ON SATURDAY AHEAD OF APPROACHING
SYSTEM...BUT IT LOOKS LIKE ANOTHER COOL DOWN IS IN STORE BY NEXT
WEEK.

&&

.AVIATION /21Z MONDAY THROUGH SATURDAY/...

MODERATE...30 TO 60 PERCENT.
HIGH...GREATER THAN 60 PERCENT.

INTO TUESDAY NIGHT.  NORTHWESTERLY WINDS SHIFT TO THE NORTHEAST...
INCREASING TUESDAY NIGHT.  GALE WARNINGS HAVE BEEN ISSUED FOR ALL
WATERS BEGINNING AT 7 PM TUESDAY NIGHT.  VISIBILITIES WILL BE
GREATLY REDUCED IN NEAR BLIZZARD TO BLIZZARD CONDITIONS AS SNOW
BEGINS LATE TUESDAY AFTERNOON.  MODERATE FREEZING SPRAY IS POSSIBLE
TUESDAY NIGHT.

OUTLOOK...WEDNESDAY THROUGH SATURDAY...
