AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
815 AM EDT MON MAR 21 2011
.SYNOPSIS...
LOW PRESSURE CROSSING NEW ENGLAND LATER TODAY WILL BRING A
MIXTURE OF RAIN AND SNOW...WITH SEVERAL INCHES OF ACCUMULATION
POSSIBLE ACROSS THE INTERIOR HIGH TERRAIN. ANOTHER AREA OF LOW
PRESSURE WILL PASS JUST SOUTH OF NEW ENGLAND LATE WEDNESDAY AND
WEDNESDAY NIGHT WITH POTENTIAL FOR ACCUMULATING SNOW THROUGH
THURSDAY. COLDER THAN NORMAL TEMPERATURES WILL PREVAIL DURING THE
LATTER HALF OF THE WEEK AND NEXT WEEKEND.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
A RELATIVELY QUICK SHOT OF PRECIP WILL MOVE THROUGH SNE TODAY WITH
MOST OF THE QPF LIKELY FALLING IN ABOUT 6 HOURS. PRECIP MOVES
INTO W ZONES AROUND 12Z REACHING E COASTAL MA AND CAPE COD AROUND
MIDDAY WITH THE PRECIP TAPERING OFF LATER IN THE AFTERNOON AS BEST
LIFT MOVES TO THE EAST AND MID LEVEL DRY SLOT APPROACHES.
THE CHALLENGE FOR TODAY IS PTYPE AND SNOWFALL AMOUNTS. DESPITE
SOUTHERLY FLOW...THE COLUMN IS QUITE COLD THIS MORNING AS THE
PRECIP MOVES IN. AND PRESENCE OF LOW LEVEL DRY AIR WILL INDUCE
COOLING FROM EVAPORATION. 850 MB TEMPS INITIALLY COOL AFTER PRECIP
MOVES IN AND NAM SHOWS NOTABLE COOLING IN 2M TEMPS. THIS WILL
ALLOW PRECIP TO BEGIN AS SNOW ACROSS MUCH OF THE REGION AND IF IT
IS RAIN TO START IT SHOULD CHANGE TO SNOW AS EVAP COOLING TAKES
PLACE. SREF PTYPE INDICATES A PERIOD OF SNOW EVEN ALONG THE COAST
15-18Z WITH POSSIBLE EXCEPTION OF THE ISLANDS.
HOWEVER...ABOVE FREEZING TEMPS AND HIGH SUN ANGLE WILL PRECLUDE
ANY ACCUM NEAR THE COAST AND PRECIP WILL CHANGE TO RAIN. FURTHER
IN THE INTERIOR...SNOW WILL LAST A BIT LONGER BUT SHOULD ALSO
EVENTUALLY CHANGE TO RAIN IN THE VALLEYS FROM SW TO NE BUT
NORTHERN HIGH TERRAIN WILL LIKELY REMAIN MOSTLY SNOW.
SNOW WILL BE FIGHTING HIGH SUN ANGLE AND NEAR OR SLIGHTLY ABOVE
FREEZING TEMPS WHICH WILL LIMIT APPRECIABLE ACCUM TO HIGHER
ELEVATIONS WHICH WILL BE A BIT COOLER. ACCUM 2-6" POSSIBLE OVER
THE BERKSHIRES...MONADNOCKS AND NORTHERN ORH COUNTY HIGH TERRAIN
WITH HIGHEST AMOUNTS OVER THE MONADNOCKS IN S NH. FOR THE REST OF
THE INTERIOR...ACCUM WILL LIKELY BE LIMITED TO AN INCH OR 2 ON
COLDER SURFACES...BUT COULD SEE LOCALLY HIGHER AMOUNTS UP TO 3" OVER
N CT HIGHER TERRAIN.
NO CHANGES TO CURRENT WINTER WEATHER ADVISORY.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM TUESDAY/...
DRY SLOT WILL BE MOVING INTO THE REGION BY THIS EVENING SO ANY
LINGERING RAIN SHOWERS SHOULD END QUICKLY. SECONDARY COASTAL LOW
WILL DEVELOP E OF NEW ENG AND AS THIS LOW INTENSIFIES NW FLOW
WILL BE INCREASING. SOME WRAP AROUND MOISTURE MAY AFFECT FAR N AND
W ZONES WITH A FEW SNOW SHOWERS...OTHERWISE PARTIAL CLEARING
EXPECTED OVERNIGHT.
&&
.LONG TERM /TUESDAY THROUGH SUNDAY/...
MEDIUM RANGE MODELS IN DECENT AGREEMENT EARLY...THEN DIFFERENCES
EXIST FOR THE MAIN SYSTEM MOVING S OF NEW ENGLAND LATE WEDNESDAY
THROUGH THURSDAY. BEYOND THIS...FAIR AGREEMENT WITH HIGH PRESSURE
BUILDING OUT OF CENTRAL CANADA. SHOULD SEE MAINLY DRY WEATHER BUT
COLDER THAN NORMAL CONDITIONS THROUGH NEXT WEEKEND. HAVE STARTED TO
NOTE TIMING ISSUES WITH SYSTEMS WORKING OUT OF THE WESTERN U.S. AS A
LONG WAVE TROUGH BREAKS DOWN TO BECOME A NEARLY ZONAL FLOW BY LATE
THIS WEEK ACROSS THE CENTRAL AND EASTERN U.S. USUALLY...TIMING OF
INDIVIDUAL SYSTEMS IS DIFFICULT WITH THIS FAST FLOW.
TUESDAY...HIGH PRES RIDGING BUILDING OUT OF QUEBEC AND EASTERN
ONTARIO WILL KEEP DRY BUT COOL WEATHER ACROSS THE REGION. WITH THE
EXITING LOW TO THE E AND STRONG HIGH PRES TO THE NORTH...EXCELLENT
MIXING AND A 35-40 KT LOW LEVEL JET BETWEEN 925 AND 850 HPA WILL
SUPPORT GUSTY NW WINDS. GUSTS COULD REACH 25-30 KT ESPECIALLY ACROSS
THE HIGHER TERRAIN AND ALONG THE COAST. THE WINDS WILL DIMINISH WITH
SUNSET.
WEDNESDAY-THURSDAY...LAST FEW OP MODEL RUNS CONTINUE TO SIGNAL LOW
PRES WORKING OUT OF THE OHIO VALLEY OFF THE NJ COAST DURING THIS
TIMEFRAME. HOWEVER...THERE ARE TIMING AND PLACEMENT DIFFERENCES
BETWEEN THE GFS/ECMWF AND THE GGEM/NAM. THE GFS/ECMWF REMAIN
CONSISTENT WITH THEIR TIMING AND TRACK...WHILE THE GGEM/NAM ARE A
BIT SLOWER AND ACTUALLY PUSH THE PRECIP SHIELD A BIT FURTHER S.
SO...STILL SOME ISSUES TO WORK OUT...BUT STILL HAVE MEDIUM
CONFIDENCE WITH THIS MORNINGS FORECAST.
EXPECT PRECIP SHIELD TO MOVE INTO THE CT VALLEY BY MID MORNING...
THEN WILL WORK E DURING THE AFTERNOON. DOES LOOK LIKE THE BEST LOW
LEVEL MOISTURE CONVERGENCE AND LIFT WILL OCCUR ACROSS CT/RI/SE
MA...SO KEPT LIKELY POPS...BUT COULD LIFT FURTHER N ACROSS MOST
AREAS BY EVENING.
WITH THE CONTINUED ONSHORE FLOW...MAINLY FROM THE E-NE...EXPECT
PRECIP TO BE MAINLY RAIN ALONG THE COAST AND ACROSS SOUTHERN AREAS
WITH MIX OF RAIN...SNOW AND SLEET WELL INLAND AND ACROSS THE HIGHER
TERRAIN FOR THE DAYLIGHT HOURS OF WEDNESDAY AND THURSDAY. WITH THE
BEST LIFT AND ENERGY MOVING S OF THE REGION WEDNESDAY NIGHT...EXPECT
MAINLY SNOW FOR MOST AREAS AWAY FROM THE COAST...OR AT LEAST A MIX
OF RAIN/SNOW.
NOW...THE BIG QUESTION...HOW MUCH SNOW WILL FALL. TOUGH CALL
ACTUALLY CONSIDERING THE GENERALLY LOW SNOW-TO-RAIN RATIO...BUT
THERE IS STILL THE POTENTIAL FOR AT LEAST ADVISORY LEVEL SNOWS
ACROSS THE EAST SLOPES OF THE BERKSHIRES...THE MONADNOCKS AND
WORCESTER HILLS. THIS WILL BE ALL DEPENDENT UPON WHETHER WINDS START
TO BACK QUICKER ON WEDNESDAY NIGHT ALLOWING THE COLDER AIR TO BE
DRAWN IN WHETHER EVEN MORE SNOW FALLS.
EXPECT PRECIP TO LINGER THROUGH MOST OF THURSDAY...THOUGH WILL TAPER
OFF TO RAIN AND/OR SNOW SHOWERS ACROSS WESTERN AREAS IN THE
AFTERNOON. RAIN SHOWERS COULD LINGER INTO EARLY THURSDAY NIGHT ALONG
THE COAST.
FRIDAY-SUNDAY...MODELS IN GENERAL AGREEMENT WITH HIGH PRES AGAIN
NOSING OUT OF CENTRAL CANADA BRINGING MORE DRY BUT UNSEASONABLY COLD
WEATHER TO THE REGION FOR FRIDAY AND SATURDAY. AS MENTIONED
EARLY...A NEARLY ZONAL UPPER LEVEL FLOW APPEARS TO BE SETTING UP SO
TIMING OF SYSTEMS MOVING IN THIS TYPE OF WIND FLOW IS TOUGH AT BEST.
SUCH IS THE CASE FOR A POTENTIAL SYSTEM WORKING ACROSS THE S CENTRAL
U.S. ON SUNDAY. LOOKS LIKE THIS SHOULD NOT AFFECT THE REGION...AT
LEAST AT THIS POINT. HOWEVER...IF ONE IS LOOKING AT THE 00Z OP GFS
RUN...THERE IS A MUCH DIFFERENT SOLUTION OFFERED. NOT ONLY ARE THE
EXTENDED OP MODEL RUNS SHOWING LITTLE CONTINUITY...EVEN THE
ENSEMBLES STARTING TO SHOW A WIDE VARIANCE OF SOLUTIONS DURING THIS
TIMEFRAME. THIS LENDS TO VERY LITTLE IF ANY CONFIDENCE ON THIS
PORTION OF THE FORECAST...MAINLY FOR NEXT WEEKEND.
&&
.AVIATION /12Z MONDAY THROUGH FRIDAY/...
FORECASTER CONFIDENCE LEVELS...
LOW...LESS THAN 30 PERCENT
MEDIUM...30 PERCENT TO 60 PERCENT
HIGH...GREATER THAN 60 PERCENT
TODAY...MEDIUM TO HIGH CONFIDENCE IN TAFS. EXPECT CIGS VSBYS TO
LOWER TO MVFR AND IFR WITH -RA AND -SN MOVING OVER THE REGION.
PRECIP WILL START BY MID MORNING W...AND THEN BY LATE MORNING E.
SSE WINDS AROUND 10 KTS MOST OF THE DAY.
TONIGHT...MEDIUM TO HIGH CONFIDENCE IN TAFS. EXPECT LINGERING MVFR
AND IFR CONDITIONS THROUGH THE EVENING IMPROVING TO VFR BY
MIDNIGHT ACROSS MOST TERMINALS. WINDS SHIFTING TO W WITH GUTS TO 25
KTS TOWARD MORNING.
KBOS TERMINAL...CONDITIONS TO GRADUALLY DECREASE TO IFR AROUND
MID DAY. CONFIDENCE IS MEDIUM TO HIGH IN TREND BUT ONLY MEDIUM IN
TIMING. EXPECT MIX OF -RA AND WET -SN TO BUILD OVER THE TERMINAL
THROUGH THE MORNING. ACCUMS OF -SN WILL BE LIGHT AND ONLY ON
NORMALLY COLDER SFCS. EXPECT A TRANSITION TO ALL -RA THROUGH THE
AFTERNOON. IFR AND MVFR CONDITIONS TO LINGER INTO THE EVENING THEN
EXPECT IMPROVEMENT TO VFR BY MIDNIGHT. WINDS SSE 10 TO 15 KTS
THROUGH THE DAY...SHIFTING TO WNW WITH GUSTS APPROACHING 25 KTS
OVERNIGHT INTO THE MORNING.
OUTLOOK...TUESDAY THROUGH FRIDAY...
TUESDAY...HIGH CONFIDENCE FOR VFR CONDITIONS. N-NW WINDS WILL GUST
UP TO 30 KT MAINLY NEAR THE COAST AND AROUND 25 KT ACROSS THE HIGHER
TERRAIN INLAND.
WEDNESDAY-THURSDAY...MEDIUM CONFIDENCE. EXPECT CIGS/VSBYS TO LOWER
TO MVFR-IFR FROM W-E STARTING BY MID MORNING OVER THE CT VALLEY THEN
IN THE AFTERNOON ACROSS THE E. EXPECT A MIX OF RAIN...SLEET AND/OR
SNOW WITH MAINLY RAIN ALONG THE COAST. SHOULD SEE PRECIP CHANGE OVER
TO ALL SNOW AWAY FROM THE COAST BY EARLY WEDNESDAY NIGHT. WILL
CHANGE BACK TO MIXED RAIN/SNOW OR ALL RAIN AS TEMPS RISE DURING
THURSDAY MORNING. EXPECT PRECIP TO TAPER OFF DURING THE AFTERNOON
ACROSS CENTRAL AND WESTERN AREAS...BUT MAY LINGER INTO THURSDAY
NIGHT ALONG THE E COAST. CONDITIONS SHOULD IMPROVE ACROSS ALL AREAS
BY AROUND MIDNIGHT.
FRIDAY...MEDIUM CONFIDENCE FOR VFR CONDITIONS. NW WINDS GUSTING TO
25 KNOTS MAINLY ACROSS THE HIGHER TERRAIN.
&&
.MARINE...
TODAY...WE KEPT THE SAME CONFIGURATION OF SCA AND GALES.
SOUTHERLY LLJ UP TO 50 KT MAY BRING A BRIEF PERIOD OF GALES TO THE
EASTERN WATERS LATE TODAY. RELATIVELY COLD LOW LEVEL TEMPS OVER
WARMER SST AND GOOD PRES FALLS WILL PROMOTE DECENT MIXING WHICH
SHOULD ALLOW FOR A BRIEF PERIOD OF G35 KT.
TONIGHT...LLJ MOVES TO THE E IN THE EVENING SO EXPECT WINDS TO
TEMPORARILY DIMINISH. BUT AS LOW PRES INTENSIFIES E OF NEW
ENG...NW WINDS WILL INCREASE AFTER MIDNIGHT WITH NEAR GALE FORCE
GUSTS POSSIBLE TOWARD DAYBREAK OVER THE OUTER WATERS.
OUTLOOK...TUESDAY THROUGH FRIDAY...
TUESDAY...MARGINAL NORTHWEST GALES POSSIBLE ON THE WATERS EAST AND
SOUTHEAST OF CAPE COD. OTHERWISE SMALL CRAFT ADVISORY CRITERIA ON
MOST WATERS FOR WINDS AND SEAS...DIMINISHING TUESDAY NIGHT.
OUTLOOK...TUESDAY THROUGH FRIDAY...
TUESDAY...EXPECT N WINDS TO GUST UP TO 30 KT. LOW PROBABILITY OF 35
KT GUSTS ON THE EASTERN OUTER WATERS EARLY. OTHERWISE...SMALL CRAFT
ADVISORY CRITERIA WINDS AND SEAS WILL CONTINUE INTO EARLY TUESDAY
NIGHT THEN DIMINISH.
WEDNESDAY...EXPECT SEAS AT 5-6 FT TO LINGER ON THE EASTERN OUTER
WATERS. OTHERWISE...WINDS AND SEAS BELOW SMALL CRAFT CRITERIA.
WEDNESDAY NIGHT-THURSDAY...E-NE WINDS WILL INCREASE...WITH GUSTS UP
TO 25-30 KT. LOW PROBABILITY OF GUSTS NEAR GALE FORCE E AND S OF
NANTUCKET. EXPECT SEAS TO BUILD TO 5-7 FEET ON MOST OPEN WATERS
ESPECIALLY ALONG THE E COAST.
THURSDAY NIGHT...WINDS BACK TO N AND DIMINISH BELOW SMALL CRAFT
LEVELS...BUT SEAS WILL LINGER AT 5-6 FT MAINLY ON THE OUTER WATERS.
FRIDAY...NW WINDS WILL GUST UP TO 25 KT FROM LATE MORNING THROUGH
THE AFTERNOON. SEAS WILL REMAIN AROUND 5 FT ON THE OUTER WATERS.
