AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
354 AM EDT MON MAR 9 2009
.SYNOPSIS...
LOW PRESSURE TRACKING SOUTH OF NEW ENGLAND TODAY WILL BRING
ACCUMULATING SNOWS TO NORTHERN MASSACHUSETTS AND SOUTHERN NEW HAMPSHIRE.
DRY WEATHER FOLLOWS TONIGHT AND TUESDAY AS HIGH PRESSURE BUILDS OVER
THE REGION. MORE WINTRY PRECIPITATION IS POSSIBLE INLAND TUESDAY
NIGHT...THEN CHANGING OVER TO ALL RAIN WEDNESDAY. DRIER AND COLDER
THAN NORMAL WEATHER IS EXPECTED LATE IN WEEK AND INTO NEXT WEEKEND.
&&
.NEAR TERM /UNTIL NOON TODAY/...
THE PREVIOUS FORECAST IS PRETTY MUCH ON TRACK. RAIN HAS MOVED ONTO
MUCH OF NORTHEAST CONNECTICUT AND FAR SOUTHWEST MASSACHUSETTS EARLY
THIS EVENING. THE PRECIPITATION SHIELD CONTINUE TO ADVANCE
NORTHEAST OVERNIGHT...FINALLY REACHING NORTHEAST MA AFTER MIDNIGHT.
THEREFORE...WILL CONTINUE TO SHOW CATEGORICAL POPS WORKING NORTHEAST
OVER THE NEXT 6 HOURS.
ITS QUITE WARM IN THE BOUNDARY LAYER THIS EVENING...SO WHEN THE
PRECIPITATION ARRIVES IT WILL BE IN THE FORM OF RAIN ACROSS MOST OF
THE REGION EVEN INTO THE LOWER ELEVATIONS OF SOUTHERN NH. IN
FACT...ALL THE PRECIPITATION WILL REMAIN RAIN IN AREAS SOUTH OF THE
MA PIKE THROUGH 12Z MONDAY. AS WE WORK NORTHWARD...AREAS FROM THE
MA PIKE TO ROUTE 2 SHOULD INITIALLY SEE RAIN.
HOWEVER...EVAPORATIONAL COOLING IN THIS REGION SHOULD RESULT IN THE
PRECIPITATION CHANGING TO SLEET/SNOW BETWEEN 9Z AND 12Z MONDAY. THE
MID LEVEL TEMPERATURES IN THIS REGION REMAIN MARGINAL BETWEEN SLEET
AND SNOW...AND POSSIBLY EVEN STILL SOME RAIN ON THE IMMEDIATE COAST
BECAUSE OF BOUNDARY LAYER ISSUES. HOWEVER...WHEN THE PRECIPITATION
COMES DOWN HEAVY THERE MAY BE ENOUGH COOLING IN THE COLUMN TO RESULT
IN A CHANGE OVER TO SNOW. FINALLY...WORKING UP FROM ROUTE 2 IN FAR
NORTHERN MA AND INTO SOUTHERN NH AN INITIAL PERIOD OF RAIN/SLEET
SHOULD CHANGE MAINLY TO SNOW BETWEEN 6Z AND 9Z.
AS THE PREVIOUS FORECAST MENTIONED...IT LOOKS LIKE MOST OF THE
ACCUMULATING SNOW THROUGH 12Z WILL BE FOUND NORTH OF ROUTE 2 IN FAR
NORTHERN MA AND INTO SOUTHERN NH. THE NAM SHOWS A FAIRLY IMPRESSIVE
BURST OF OMEGA IN THE SNOWGROWTH REGION...WHILE THE GFS HAS SOME DRY
AIR IN THE MID LEVELS STRUGGLING TO SATURATE. THINKING IS THAT WE
COULD SEE A PRETTY GOOD BURST OF SNOW FOR A FEW HOURS IN THIS REGION
BEFORE MID LEVEL DRY AIR MOVES BACK INTO THE REGION.
OTHERWISE...A MIXTURE OF SLEET AND SNOW MAY BE FALLING ALL THE WAY
DOWN TO THE MA TURNPIKE AT 12Z AND A SMALL SLUSHY ACCUMULATION MAY
OCCUR ON THE GRASS...BUT THINK THE ROADS WILL BE WET EXCEPT PERHAPS
IN THE HIGHER TERRAIN OF THE WORCESTER HILLS.
ALL IN ALL...NO CHANGES ANTICIPATED TO ANY OF THE WINTER WEATHER
ADVISORY HEADLINES AT THIS POINT.
&&
.SHORT TERM /NOON THROUGH 6 PM TODAY/...
LOW PRESSURE WILL CONTINUE TO DEVELOP SOUTH OF LONG ISLAND AT THE
BEGINNING OF THE FORECAST PERIOD. IT WILL LIKELY BE RAINING ACROSS
MUCH OF THE FORECAST AREA ALONG AND SOUTH OF THE MASS PIKE AT THIS
TIME...WITH SNOW...SLEET...OR SNOW/SLEET MIXED NORTH OF THE
PIKE...ESPECIALLY ACROSS THE HIGHER ELEVATIONS AS WELL AS SOUTHERN
NEW HAMPSHIRE. AS THE EARLY MORNING PROGRESSES...THE MIXED PRECIP
ALONG AND NORTH OF THE PIKE SHOULD GRADUALLY CHANGE TO SNOW AS THE
COLUMN COOLS. AREAS TO THE SOUTH OF THE PIKE SHOULD GRADUALLY CHANGE
TO SNOW STARTING LATE MORNING TO EARLY AFTERNOON AS COLD AIR
CONTINUES TO FILTER SOUTHWARD AS THE LOW CONTINUES TO DEVELOP AND THE
STRONG SHORT WAVE APPROACHES.
BASED ON WHAT WE/RE SEEING IN THE DATA...SUCH AS MODELED QPF...SNOW
GROWTH...OMEGA PROFILES...TEMPERATURE PROFILES...AND CLIMO WE THINK
THE BEST COURSE OF ACTION AT THIS TIME IS TO ISSUE A WINTER WEATHER
ADVISORY FOR AREAS ALONG AND NORTH OF THE MASS PIKE...INCLUDING
SOUTHERN NEW HAMPSHIRE. THE ADVISORY /AT THIS TIME/ DOES NOT INCLUDE
SUFFOLK COUNTY. WE/LL GO WITH 2 TO 4 INCHES IN THE MASS PORTION OF
THE ADVISORY /WITH LOCALLY HIGHER AMOUNTS AT THE HIGHER ELEVATIONS/
WITH 3 TO 6 INCHES IN NEW HAMPSHIRE.
TO THE SOUTH OF THE ADVISORY AREA WILL GO WITH A COATING TO 2
INCHES...WITH SLIGHTLY HIGHER LOCAL AMOUNTS POSSIBLE ACROSS THE
HIGHER TERRAIN.
THERE MAY BE A BRIEF BREAK IN THE PRECIPITATION LATE MORNING OR VERY
EARLY AFTERNOON AS NARROW DRY SLOT MOVES ACROSS SOUTHERN ZONES.
HOWEVER...THAT SHOULD BE SHORT LIVED AS THE MID LEVELS MOISTEN UP
AGAIN WITH THE APPROACH OF THE SHORT WAVE ITSELF. EVEN AREAS SUCH AS
PROVIDENCE TO TAUNTON TO PLYMOUTH SHOULD SEE SNOW BY AFTERNOON WITH
AN INCH OR SO POSSIBLE. RAIN/SLEET MAY TRANSITION TO A BRIEF PERIOD
OF SNOW BEFORE ENDING ON THE CAPE AND ISLANDS.
TEMPS SHOULD GRADUALLY FALL THROUGHOUT THE DAY. WINDS WILL INCREASE
NOTICEABLY AS THE MORNING PROGRESSES.
OVERALL...THERE IS STILL QUITE A BIT OF UNCERTAINTY IN THE SNOWFALL
FORECAST AND CHANGEOVER TIMES. THE NEXT SHIFT SHOULD GET A BETTER
IDEA ON HOW THINGS WILL EXACTLY PAN OUT AS THE DATA SHOULD BECOME
CLEARER. SOME CHANGES TO THE SNOW AMOUNTS AND ADVISORY AREA MAY BE
NECESSARY.
&&
.LONG TERM /TONIGHT THROUGH SUNDAY/...
GIVEN THE WINTRY WEATHER EXPECTED TODAY WE DID NOT DEVOTE MUCH TIME
TO THE EXTENDED...WITH NO CHANGES TO THE FORECAST BEYOND TUE NIGHT.
HOWEVER THE FOLLOWING ARE SOME THOUGHTS REGARDING THE NEW 00Z MODEL
GUIDANCE.
MONDAY NIGHT...
MID LEVEL TROF AND ASSOCIATED COASTAL LOW WILL EXIT SOUTHEAST NEW
ENGLAND AND MOVE SEAWARD. BACK EDGE OF DEEPER MOISTURE AND
NORTHEAST FLOW MAY RESULT IN SOME LINGERING LIGHT SNOW OR FLURRIES
MON EVENING ACROSS EASTERN MA AND RI. OTHERWISE EXPECT DECREASING
CLOUDS AS DEEP LAYER RIDGE BUILDS EASTWARD INTO THE REGION. IT WILL
BE A CHILLY NIGHT ESPECIALLY ACROSS NORTHERN MA AND SOUTHWEST NH
WHERE TODAY/S EXPECTED SNOWFALL WILL COMBINE WITH LIGHT WINDS AND
CLEAR SKIES FOR TEMPS TO PLUMMET INTO THE TEENS. ELSEWHERE LOWS WILL
BE IN THE 20S.
TUESDAY...
RIDGING AT ALL LEVELS WILL PROMOTE SUNSHINE EARLY IN THE DAY.
HOWEVER UPPER AIR PATTERN IS PROGRESSIVE WITH RIDGE AXIS MOVING
OFFSHORE DURING THE AFTERNOON. THIS WILL YIELD INCREASING CLOUDS TUE
AFTERNOON. 00Z GFS HAS TRENDED SLOWER WITH ONSET OF PRECIP FROM NEXT
SYSTEM...KEEPING THE REGION DRY MOST OF TUE WITH JUST A LOW PROB OF
RAIN ENTERING WESTERN NEW ENGLAND LATE IN THE DAY. THIS IS IN
AGREEMENT WITH THE 00Z NAM/RGEM AND 21Z SREF.
TUESDAY NIGHT...
PRECIP LIKELY LATER TUE NIGHT AS WARM FRONT APPROACHES SOUTHERN NEW
ENGLAND FROM THE SOUTHWEST. COLD AIR OVER THE INTERIOR TAKES SOME
TIME TO ERODE...SO A WINTRY MIX OF PRECIP IS POSSIBLE IN THIS AREA.
MODEL SOUNDINGS AND SREF PTYPES SUGGEST THE MOST LIKELY PTYPE WILL
BE SLEET AND FREEZING RAIN. THEREFORE COULD BE SOME SLIPPERY TRAVEL
LATE TUE NIGHT INTO EARLY WED ACROSS THE INTERIOR. HOWEVER THIS
SHOULD NOT BE A PROLONG EVENT AS INCREASING SOUTHERLY LOW LEVEL FLOW
SHOULD EVENTUALLY WIN OUT AND COMPLETELY ERODE LOW LEVEL COLD AIR.
WEDNESDAY...
SHOWERS EXPECTED WEDNESDAY AS A COLD FRONT MOVES ACROSS THE REGION.
ANY FROZEN PRECIP EARLY WED MORNING WILL RAPIDLY CHANGE TO ALL RAIN
IN RESPONSE TO STRONG SOUTHERLY FLOW AHEAD OF APPROACHING COLD
FRONT. THIS STRONG WARM AIR ADVECTION MAY PUSH HIGHS INTO THE 50S
WED AFTN BEFORE THE FRONTAL PASSAGE. 00Z MODELS IN GOOD AGREEMENT ON
FRONT CLEARING THE REGION LATE WED/WED EVENING.
THURSDAY THROUGH SUNDAY...
00Z MODEL GUIDANCE IN GOOD AGREEMENT THIS PERIOD WITH A BROAD COLD
TROF SETTING UP ACROSS SOUTHEAST CANADA AND THE NORTHEAST. 00Z GFS
AND GGEM COOLING 850 TEMPS DOWN TO -12C TO -14C HERE THU AND
FRI...THEN EASING TO -6C TO -8C NEXT WEEKEND. THIS WILL RESULT IN
BELOW NORMAL TEMPS WITH HIGHS LIKELY ONLY IN THE 30S THU AND
FRI...THEN POSSIBLY WARMING TO 40 OR SO OVER THE WEEKEND. IN FACT
TROF IS SOMEWHAT ANOMALOUS FOR THIS TIME OF YEAR...AS IT SUPPRESSES
STORM TRACK SOUTH OF NEW ENGLAND. THIS RESULTS IN A STALLED FRONTAL
BOUNDARY OVER THE MID ATLC OR SE STATES WITH WAVES OF LOW PRES
RIDING THE FRONT...BUT PASSING WELL TO THE SOUTH OF THE AREA. WILL
HAVE TO WATCH THIS CLOSELY AS THE WEEK PROGRESSES GIVEN THE COLD
AIRMASS OVER THE NORTHEAST...YIELDING THE POTENTIAL FOR WINTRY
WEATHER IF THE STORM TRACK SHIFTS NORTHWARD.
&&
.AVIATION /08Z MONDAY THROUGH FRIDAY/...
TODAY...INITIALLY...MAINLY RAIN SOUTH OF THE MA PIKE WITH
SNOW/SLEET/RAIN NORTH OF THE MA PIKE. THE SNOW/SLEET LINE WILL PUSH
TOWARDS THE SOUTH COAST DURING THE DAY MONDAY AS COLDER AIR WORKS
INTO THE SYSTEM.
OUTLOOK /TONIGHT THROUGH FRIDAY/...

IMPROVING TO VFR WITH CLEARING SKIES.
TUESDAY...VFR...BUT LOWERING CIGS AFTERNOON BAF/BDL WITH CHC RA/SN

POTENTIAL FOR A WINTRY MIX BDL/BAF/ORH/MHT...CHANGING TO RAIN BY WED
MORNING. ELSEWHERE MAINLY RAIN EXPECTED.
THURSDAY AND FRIDAY...VFR.

.MARINE...
TODAY...WAVE OF LOW PRESSURE REDEVELOPING SOUTH OF LONG ISLAND TODAY WILL
ALLOW FOR STRENGTHENING EASTERLY WINDS MONDAY...WHICH MAY RESULT IN
MARGINAL GALES NEAR AND AROUND NANTUCKET. HAVE ISSUED A GALE WATCH
FOR THAT AREA ATTM AS WE ARE A BIT UNCERTAIN IF WE/LL GET WIDESPREAD
LOW END GALES OR HIGH END SCA CONDITIONS. FOR ALL OTHER WATERS WE
HAVE ENOUGH CONFIDENCE TO GO WITH SCA.
OUTLOOK /MONDAY NIGHT THROUGH FRIDAY/...
TONIGHT...MARGINAL NE GALE POSSIBLE EARLY THE WATERS SOUTHEAST OF THE
CAPE AND NANTUCKET. OTHERWISE N-NE WINDS DIMINISHING OVERNIGHT AS
HIGH PRES BUILDS FROM W TO E. NE SWELL WILL PERSIST. VSBY IMPROVING.
TUE...LIGHT AND VARIABLE WINDS BECOMING SSE AS HIGH PRES MOVES
OFFSHORE. MODEST NE SWELL PERSISTING ACROSS THE OUTER OCEAN WATERS.
TUESDAY NIGHT AND WEDNESDAY...STRONG COLD FRONT APPROACHING THE
REGION FROM THE WEST. STRONG WINDS ALOFT WILL LIKELY NOT MIX TO THE
SURFACE GIVEN THE COLD OCEAN WATERS. SOUNDING DATA SUGGEST S WINDS
OF 15-20 KT WITH GUSTS TO 25 POSSIBLE. VSBY WILL BE REDUCED IN FOG
AND SHOWERS. COLD FRONT SWEEPS ACROSS THE AREA SOMETIME LATE WED OR
WED EVENING. BEHIND THE FRONT...IMPROVING VSBYS WITH A WIND SHIFT TO
THE WNW WITH WIND SPEEDS OF 20-30 KT.
