AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
447 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/...
AN EXTREMELY CHALLENGING FORECAST IN REGARDS TO PRECIPITATION TYPE
AND SNOWFALL AMOUNTS.
A VERY DYNAMICAL UPPER LEVEL DISTURBANCE WILL GENERATE A PERIOD OF
VERY STRONG OMEGA IN THE SNOWGROWTH REGION TO MANY AREAS ALONG AND
NORTH OF THE PIKE THIS MORNING. THE SOUNDINGS ACROSS MUCH OF THIS
REGIONAL BECOME ISOTHERMAL AND TAKEN VERBATIM...PRODUCE SEVERAL
HOURS OF HEAVY WET SNOW. THE PRIMARY TIME OF CONCERN WOULD BE BETWEEN
6 AM AND NOON...BUT WE DO NOT WANT TO GET TO PRECISE SINCE THERE ARE
A FEW DIFFERENCES IN TIMING. WE HAVE NOTED THAT THE DRIER AIR IS COMING
DOWN FROM THE NORTHEAST AND THIS IS APPARENT IN THE LATEST
OBSERVATIONS. DEWPOINTS HAVE NOW FALLEN INTO THE 20S ACROSS NORTH
CENTRAL/NORTHEAST MA SETTING THE STAGE FOR SOME GOOD EVAPORATIONAL
COOLING.
AGAIN...THE SOUNDINGS ARE SO CLOSE A SMALL MODEL ERROR CAN MAKE THE
DIFFERENCE BETWEEN RAIN/SLEET AND SEVERAL HOURS OF HEAVY SNOW THAT
QUICKLY ACCUMULATES. THERE IS NO WAY TO HAVE HIGH CONFIDENCE IN
THESE SITUATIONS. HOWEVER...BASED ON THE TREMENDOUS OMEGA IN THE
SNOW GROWTH REGION THAT THE NAM SHOWS...FEEL BOSTON...TO NEAR
WORCESTER...TO ORANGE POINTS NORTHWARD WILL SEE RAIN CHANGE TO A
PERIOD OF HEAVY WET SNOW THIS MORNING WITH INTENSE VERTICAL
MOTION. WITH ALL THAT SAID...WILL GO AHEAD AND EXTEND THE WINTER
WEATHER ADVISORY INTO COASTAL NORTHEAST MA...AS WELL AS BOSTON.
ACCUMULATIONS ARE TRICKY IN THIS REGION AND WILL DEPEND ON HOW
QUICKLY WE TRANSITION TO SNOW AND INTENSITY. HOWEVER...WILL STICK
WITH 2 TO 5 INCHES ACROSS MOST OF NORTHERN MA.
WE ALSO UPGRADED SOUTHERN NH ALONG WITH FAR NORTHWEST MIDDLESEX AND
WESTERN ESSEX COUNTIES TO WARNINGS. SNOW GROWTH AND DYNAMICS ARE
QUITE IMPRESSIVE...SO WE EXPECT RAIN/SLEET TO QUICKLY CHANGE TO A
PERIOD OF HEAVY WET SNOW THIS MORNING. WHETHER OR NOT WE MEET THE
SPECIFIC WARNING CRITERIA IN THIS AREA IS A BIT UNCERTAIN...BUT
CERTAINLY POSSIBLE. HOWEVER...SINCE THIS WILL BE A HEAVY WET SNOW
IT WILL HAVE THE POTENTIAL FOR A FEW DOWNED TREE LIMBS/ISOLATED
POWER OUTAGES. THIS GAVE US ENOUGH INFORMATION TO UPGRADE TO A
MARGINAL WARNING WITH 4 TO 7 INCHES OF ACCUMULATION. WE WILL HAVE
TO WATCH THE REST OF NORTH CENTRAL/NORTHEAST MA FOR A POSSIBLE
UPGRADE. THESE DYNAMICAL SITUATIONS CAN QUICKLY EVOLVE AND RESULT
IN RAIN CHANGING TO HEAVY WET SNOW.
MEANWHILE...TO THE SOUTH OF THE MA PIKE EXPECT MAINLY RAIN AND
PERHAPS SOME SLEET THIS MORNING. HOWEVER...AFTER THE MAIN BATCH OF
LIFT GOES THROUGH THE REGION...THE MODELS SHOW PRECIPITATION
LINGERING THIS AFTERNOON WITH THE INVERTED TROUGH ACROSS EASTERN
SECTIONS. WE SHOULD SEE COOLING IN THE MID LEVELS SENDING THE
RAIN/SNOW LINE TO THE SOUTH COAST.
TO THE SOUTH OF THE MA PIKE...STUCK WITH ONE HALF TO 2 INCHES OF
SNOW. HOWEVER...WE DID NOTE THAT THE 6Z NAM HAS COME IN A TAD
COLDER. ITS CERTAINLY POSSIBLE THAT WE COULD END UP WITH A BIT
MORE...BUT THE SOUNDINGS STILL SHOWED A MID LEVEL WARM AREA SO KEPT
AMOUNTS CONSERVATIVE.
ALSO...ISSUED A WIND ADVISORY FOR NANTUCKET WITH INCREASING GRADIENT
IN ASSOCIATION WITH THE LOW PRESSURE SYSTEM.
&&
.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 /09Z MONDAY THROUGH FRIDAY/...
TODAY...MVFR/IFR CONDITIONS TO THE SOUTH OF THE PIKE...WHERE RAIN
WILL CHANGE TO A PERIOD OF SNOW DURING THE AFTERNOON. TO THE NORTH
OF THE PIKE...RAIN/SLEET WILL CHANGE TO HEAVY WET SNOW AND LIKELY
RESULT IN A PERIOD OF LIFR CONDITIONS FROM THE MORNING INTO THE
EARLY AFTERNOON. WIND GUSTS OF 25 TO 30 KNOTS WILL ALSO DEVELOP ON
THE COAST THIS MORNING...WITH EVEN STRONGER WINDS AT NANTUCKET.
OUTLOOK /TONIGHT THROUGH FRIDAY/...
TONIGHT...AREAS OF MVFR POSSIBLE EARLY BOS/PVD/HYA AND ACK...OTHERWISE
IMPROVING TO VFR WITH CLEARING SKIES.
TUESDAY...VFR...BUT LOWERING CIGS AFTERNOON BAF/BDL WITH CHC RA/SN
LATE.
TUESDAY NIGHT AND WEDNESDAY...LOWERING TO MVFR/IFR WITH THE
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...EAST TO NORTHEAST WINDS INCREASE WITH THE LOW PRESSURE
RESULTING IN AN INCREASING IN THE PRESSURE GRADIENT.
THEREFORE...ISSUED GALE WARNINGS ACROSS OUR SOUTHEASTERN WATERS
INCLUDING CAPE COD BAY/NANTUCKET SOUND. WE EXPECT TO SEE 35 TO 40
KNOT WIND GUSTS DEVELOP. THE REST OF THE REGION WILL SEE SCA
CONDITIONS DEVELOP BY MID MORNING WITH 25 TO 30 KNOT GUSTS THROUGH
THE AFTERNOON.
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.
THURSDAY...DRY WEATHER WITH MODEST NW WINDS OF 20-30 KT.
FRIDAY...DIMINISHING WINDS /15-20 KT/ AS HIGH PRES BUILDS OVER THE
