AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
149 AM EST SUN FEB 17 2013
.SYNOPSIS...
A STRENGTHENING OCEAN STORM WILL PASS OFFSHORE LATER THIS
MORNING...BRINGING SNOW TO MOST OF THE REGION. IT WILL ALSO
GENERATE STRONG WINDS THAT WILL BRING UNSEASONABLY COLD WEATHER
FOR THE START OF THE WEEK. ANOTHER THREAT FOR RAIN AND/OR SNOW IS
POSSIBLE TUESDAY INTO TUESDAY NIGHT. UNSEASONABLY COLD WEATHER
RETURNS TOWARDS THE END OF NEXT WEEK.
&&
.NEAR TERM /UNTIL 6 AM THIS MORNING/...
INTENSIFYING OFFSHORE LOW PRESSURE IS SOUTH OF NEWPORT RI AND EAST
OF NEWPORT NEWS VA. PRESSURE FALLS OF 1MB/HOUR HAVE REACHED
SOUTHERN NEW ENGLAND WITH STRONGER VALUES OFFSHORE. EXPECT THE
WIND WILL INCREASE THROUGH THE NIGHT ESPECIALLY IN RI AND EASTERN
MASSACHUSETTS. SURFACE REPORTS SHOW LIGHT SNOW IN MANY AREAS SOUTH
OF THE MASS PIKE BUT VSBYS ARE STILL RELATIVELY HIGH SO ANY
ACCUMULATION IS HAPPENING SLOWLY.
WITH THE SURFACE LOW WELL OFFSHORE...LAND-BASED RADARS HAVE AT
BEST BEEN CATCHING THE EDGE OF THE ASSOCIATED PRECIP SHIELD. BUT
THERE ARE SIGNS OF IT FILLING IN EAST OF DELMARVA AND SOUTHERN NEW
JERSEY. THIS IS IN THE AREA WHERE MODELS SHOW DEVELOPING COUPLING
OF LOW LEVEL CONVERGENCE AND 300-400 MB DIVERGENCE. THIS AREA IS
FORECAST TO MOVE UP ACROSS THE WATERS NEAR NANTUCKET BY 12Z. THE
GFS SHOWS OMEGA IN EXCESS OF 60 MB/HOUR. SO WE ARE SHOWING
INCREASING POPS FOR THE REMAINDER OF THE NIGHT WITH CATEGORICAL
POPS IN RI AND SOUTHEAST MASS. EXPECT SIGNIFICANT ACCUMULATIONS
TO DEVELOP AROUND 4-6 AM.
MODELS HAVE FORECAST GOOD FRONTOGENETIC FORCING OVER NEW ENGLAND
DURING THE NIGHT. THIS HAS SUPPORTED THE LIGHT SNOW THAT HAS
OCCURRED. BUT DEWPOINTS HAVE BEEN LOWERING DURING THE
NIGHT...ESPECIALLY IN NORTHERN AND WESTERN SECTIONS WHERE VALUES
ARE IN THE SINGLE NUMBERS TO MID TEENS. PCPN FALLING INTO THIS AIR
HAS BEEN EVAPORATING...THUS THE RADAR ECHOES WITH LITTLE OR NO
SNOW. DEWPOINTS 20-32 IN RI AND SOUTHEAST MASS WILL BE A LITTLE
MORE HOSPITABLE FOR SNOW REACHING THE GROUND. THIS WILL LIMIT
ACCUMULATION CHANCES IN WESTERN NEW ENGLAND.
&&
.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM MONDAY/...
AS THE LOW PASSES WELL E OF THE CAPE HEADING TOWARD NOVA SCOTIA
SUNDAY...IT CONTINUES TO DEEPEN CAUSING A VERY TIGHT PRES
GRADIENT. WILL SEE STRONGEST WINDS DURING SUNDAY MORNING ALONG THE
COAST...WITH SUSTAINED WINDS AT 25-40 KT. MAY SEE SOME HIGH GUSTS
ACROSS THE HIGHER INLAND TERRAIN.
SNOW WILL CONTINUE THROUGH THE DAY ACROSS THE ADVISORY AND
WARNINGS AREAS...WHILE IT WILL TAPER OFF ACROSS THE CT VALLEY
DURING THE AFTERNOON. ANOTHER BIG QUESTION FOR THE CAPE AND
ISLANDS WILL BE HOW LOW THE VISIBILITIES WILL DROP WITH THE
HEAVIER SNOWFALL SUNDAY MORNING ALONG WITH THE INCREASING WINDS.
AT THIS POINT...FEEL THAT THE VSBYS WILL REMAIN ABOVE 1/4 MILE...
SO OPTED TO NOT PUT A BLIZZARD WARNING OUT...FOR NOW.
WILL BE A VERY COLD DAY AS WELL...WITH HIGHS ONLY IN THE
20S...EXCEPT AROUND 30 ON THE OUTER CAPE. HOWEVER...WITH THE
STRONG WINDS...EXPECT WIND CHILLS DOWN IN THE SINGLE DIGITS TO
AROUND 10.
&&
.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
HEADLINES...
* COLD AND VERY BLUSTERY SUNDAY NIGHT INTO MONDAY NIGHT
* BRIEF WET WEATHER FOR TUESDAY...PERHAPS AN INITIAL WINTRY MIX
* TURNING COLD AGAIN FOR WEDNESDAY INTO FRIDAY
* AN UNCERTAIN FORECAST FOR NEXT WEEKEND AND BEYOND
*/OVERVIEW AND MODEL CONSENSUS...
OUT TO FRIDAY...THERE IS FAIRLY DECENT AGREEMENT IN TRENDS AMONGST
THE MODEL SOLUTIONS. AN ACTIVE WEATHER PATTERN IS ANTICIPATED AS
A SERIES OF PACIFIC DISTURBANCES AMPLIFY ACROSS THE CONUS. THIS
DISTURBANCES SHOULD PROVIDE BRIEF PERIODS OF MILD WEATHER ALONG
AND AHEAD...FOLLOWED BY DRIER AND MUCH COLDER AIR BEHIND THEM.
OF NOTE IS THE PLAUSIBILITY OF A SHIFT TOWARDS A NEGATIVE PNA
/PACIFIC-NORTH AMERICAN/ TELECONNECTION IN WHICH TROUGHING IS
AMPLIFIED ACROSS THE WESTERN CONUS...WITH A PREVAILING RIDGING
PATTERN AND MILDER WEATHER FOR THE EASTERN CONUS. AM HESITANT TO
PLACE ANY BETS AS DAILY FORECASTED NORTHERN HEMISPHERIC TELE-
CONNECTIONS PER CPC HAVE BEEN INCONSISTENT FOR THE LATER HALF OF
FEBRUARY.
GENERALLY FOLLOWED A BLEND OF THE 16/12Z GFS AND ECMWF TO TREND
THE EXISTING FORECAST. DID NOT FOCUS TOO MUCH ON THE DETAILS FOR
THIS PORTION OF THE FORECAST WITH THE IMPENDING WINTER STORM LATE
TONIGHT INTO SUNDAY. WE CONTINUE TO HAVE LITTLE CONFIDENCE IN
THE DETAILS AFTER THURSDAY.
*/DAY-TO-DAY DETAILS...
SUNDAY NIGHT INTO MONDAY NIGHT...
EXPECTING WIND ADVISORIES FOR SUNDAY NIGHT INTO EARLY MONDAY WITH
W/NW GUSTS UP TO 46 MPH /40 KTS/. GALE WARNINGS OVER THE WATERS FROM
SUNDAY NIGHT THROUGH THE MAJORITY OF MONDAY. WHILE SOME LIGHT SNOW
SHOWER ACTIVITY WILL LINGER FOR THE CAPE AND ISLANDS EARLY SUNDAY
NIGHT...THE REMAINDER OF THE FORECAST SHOULD BE MOSTLY CLEAR AS A
WEAK AREA OF HIGH PRESSURE BUILDS ACROSS NEW ENGLAND LATE MONDAY
INTO THE EVENING PERIOD ALLOWING WINDS TO RELAX. CLOUDS WILL BE ON
THE INCREASE MONDAY NIGHT AHEAD OF TUESDAY/S DISTURBANCE.
WITH REGARDS TO TEMPERATURES...THE COLDER OF THE TWO NIGHTS WILL BE
SUNDAY NIGHT WITH MIN TEMPERATURES REACHING THE SINGLE DIGITS.
INCREASING CLOUDS MONDAY NIGHT WILL LIMIT MIN TEMPERATURES TO
AROUND THE TEENS. HIGHS ON MONDAY AROUND THE UPPER 20S.
TUESDAY INTO TUESDAY NIGHT...
FIRST THOUGHTS THAT COME TO MIND CONCERN THE PRE-EXISTING SNOWPACK
AND THE AGEOSTROPHIC FLOW WITHIN THE BOUNDARY LAYER. STILL HAVE
SUBSTANTIAL SNOW DEPTHS ACROSS THE INTERIOR...COUPLED WITH A
MODEL FORECASTED NORTHEASTERLY AGEOSTROPHIC FLOW FROM H975-H925...
KEY UPON THE PLAUSIBILITY OF A SHALLOW COLD AIR MASS REMAINING
AT THE SURFACE ACROSS INTERIOR NEW ENGLAND /MAINLY WITHIN THE
VALLEYS OF S NH AND W MA...AND PERHAPS N CT/. SUBSEQUENTLY...AS
A WARM FRONT SWEEPS NORTH AND EAST TOWARDS NEW ENGLAND...THERE IS
UNCERTAINTY AS TO WHETHER A COLD AIR DAMMING SETUP MAY PRE-EXIST
RESULTING IN ANY OVERRUNNING PRECIPITATION FALLING AS A WINTRY
MIX AT THE ONSET. BOTH THE GFS AND ECMWF KEY UPON THE PREVAILING
S/SW FLOW ALONG AND AHEAD TO ERODE ANY SHALLOW COLD LAYER
RESULTING IN MOST OF THE PRECIPITATION TO FALL IN THE FORM OF
RAIN OR A RAIN/SNOW MIX TUESDAY AFTERNOON INTO TUESDAY EVENING.
OTHERWISE...BOTH THE GFS AND ECMWF KEY UPON A NEARLY-STACKED
OCCLUDING LOW CENTER WELL NORTH AND WEST OF NEW ENGLAND. IT APPEARS
THAT THE DRY CONVEYOR BELT WRAPS INTO THE REAR OF THE SYSTEM AND
ACROSS SOUTHERN NEW ENGLAND THEREBY KEEPING MOST OF THE PRECIP LIGHT
FOR THE LATTER HALF OF TUESDAY. MUCH OF THE REGION IS DRIED OUT AND
CLEARING UNDER COLDER WESTERLY FLOW BY TUESDAY EVENING. STILL NOT
OVERLY CONFIDENT ON THIS OUTCOME. THE BETTER DYNAMICS ARE NORTH
AND WEST OF THE FORECAST REGION...WHICH ALSO FINDS ITSELF UNDER
THE RIGHT EXIT REGION OF THE UPPER-LEVEL JET.
WEDNESDAY INTO FRIDAY...
MUCH LIKE SUNDAY NIGHT INTO MONDAY NIGHT...W/NW FLOW ADVECTS
COLDER ARCTIC AIR ACROSS THE REGION. DEPENDING ON THE PROXIMITY
AND STRENGTH OF THE LOW ASSOCIATED WITH TUESDAY/S WEATHER
DEPARTING OVER THE EASTERN CANADIAN MARITIMES...NW WINDS MAY GUST
UP TO WIND ADVISORY CRITERIA. LOW CONFIDENCE WITH THIS FORECAST...
BUT SOMETHING TO BE MINDFUL. WINDS SHOULD GUST TO GALE FORCE TO
WARRANT GALE WARNINGS OVER THE WATERS. LOOKING AT NIGHTTIME LOWS
AROUND THE TEENS TO SINGLE DIGITS...WITH HIGHS AROUND THE 20S.
LOOKING LIKE THE COLDEST PERIOD WILL BE WEDNESDAY NIGHT INTO
THURSDAY.
WEEKEND...
LITTLE CONFIDENCE IS GIVEN TO THE FORECAST HEREAFTER. AS MENTIONED
EARLIER...WILL START OUT WITH A BLEND OF THE 16/12Z GFS AND ECMWF.
BOTH THE GFS AND ECMWF HINT AT SECONDARY CYCLOGENESIS SOMEWHERE OF
THE MID ATLANTIC COAST FRIDAY NIGHT INTO SATURDAY. VERY LITTLE
CONFIDENCE IN THE DETAILS AS THERE ARE A LOT OF MOVING PARTS.
&&
.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
FORECASTER CONFIDENCE LEVELS...
LOW...LESS THAN 30 PERCENT.
MODERATE...30 TO 60 PERCENT.
HIGH...GREATER THAN 60 PERCENT.
SHORT TERM...
THROUGH 12Z...MODERATE TO HIGH CONFIDENCE.
MOSTLY VFR CIGS WITH MVFR VSBYS IN SNOW...AND WITH AREAS OF HIGH-
END IFR VSBYS. CIGS AND VSBYS WILL SLOWLY FALL THE REMAINDER OF
THE NIGHT WITH IFR OR LIFR CIGS/VSBYS MOVING ONTO THE RI/SE MASS
SOUTH COAST AND ISLANDS 10-12Z/5-7 AM. SURFACE WINDS GUSTING 20-30
KNOTS MOSTLY IN SOUTHEAST MASS. EXPECT WINDS TO INCREASE THE REST
OF THE NIGHT...ESPECIALLY IN THIS AREA. TAUNTON/BOX RADAR SHOWS
NORTH WINDS 30 KNOTS AT 2000-4000 FEET. THESE WINDS WILL INCREASE
THE REMAINDER OF THE NIGHT WITH SPEEDS OF 40-50 KNOTS BY 12Z.
SUNDAY...MODERATE CONFIDENCE.
ACROSS THE CT VALLEY...MAINLY VFR. ANY MVFR VSBYS SHOULD BECOME
VFR IN THE MORNING. NORTH TO NORTHWEST WIND GUSTS TO 35 KNOTS.
CENTRAL AREAS...MAINLY MVFR BUT WITH SOME IFR ESPECIALLY HILLY
LOCATIONS SUCH AS WORCESTER. CONDITIONS IMPROVE TO VFR THIS
AFTERNOON. NORTH TO NORTHWEST WINDS INCREASE WITH GUSTS TO 40
KNOTS.
EASTERN AREAS...PERIOD OF IFR OR LIFR IN SNOW THIS
MORNING...IMPROVING TO VFR BY EVENING. NORTH WINDS GUSTING TO 45
KNOTS BECOMING NORTHWEST.
SUNDAY NIGHT...HIGH CONFIDENCE.
LINGERING MVFR CLOUDS AND SCATTERED SNOW SHOWERS IN THE EVENING ON
CAPE COD. OTHERWISE CLEARING SKIES AND VFR. NORTHWEST WINDS WILL
CONTINUE TO GUST 30-40 KNOTS.
KBOS TAF...MODERATE CONFIDENCE IN TAF...MAINLY DUE TO TIMING
ISSUES.
KBDL TAF...MODERATE CONFIDENCE IN TAF. STILL SOME UNCERTAINTY HOW
FAR WEST PRECIPITATION FROM THE COASTAL STORM REACHES. MOST OF IT
SHOULD STAY EAST OF THE CONNECTICUT VALLEY. BUT THERE WILL BE A
SHARP CUTOFF.
OUTLOOK...MONDAY THROUGH THURSDAY...
MONDAY AND MONDAY NIGHT...MODERATE TO HIGH CONFIDENCE.
PREVAILING VFR WITH BLUSTERY NW WINDS GUSTING UP TO AROUND 40 KTS
EARLY MONDAY...GRADUALLY DECLINING THEREAFTER.
TUESDAY INTO TUESDAY NIGHT...MODERATE CONFIDENCE.
LOW VFR TO MVFR FOR THE PERIOD WITH -RA...POSSIBLE WINTRY MIX
ACROSS S NH/W MA/N CT INITIALLY. S WINDS BACKING OUT OF THE W/NW AND
BECOMING BLUSTERY LATE.
WEDNESDAY INTO THURSDAY...MODERATE CONFIDENCE.
VFR WITH BLUSTERY W/NW WINDS. GUSTS UP TO AROUND 35 KTS ANTICIPATED.
&&
.MARINE...
MODERATE TO HIGH CONFIDENCE THROUGH SUNDAY.
EXPECT N WINDS TO INCREASE OVERNIGHT AS LOW PRES DEEPENS S OF THE
REGION. HAVE ISSUED STORM WARNINGS FOR MOST OF THE WATERS AS GUSTS
INCREASE TO AROUND 50 KT SUNDAY. KEPT GALES GOING ON BOSTON HARBOR
AND NARRAGANSETT BAY. SEAS WILL ALSO BUILD UP TO 15-16 FT ON THE
EASTERN OUTER WATERS. LIGHT FREEZING SPRAY LIKELY LATE
TONIGHT/SUNDAY.
OUTLOOK...SUNDAY NIGHT THROUGH THURSDAY...
SUNDAY NIGHT INTO MONDAY NIGHT...MODERATE TO HIGH CONFIDENCE.
GALE WARNINGS ANTICIPATED THROUGH MONDAY...DOWNGRADING TO SMALL
CRAFT ADVISORIES FOR MONDAY NIGHT. LOW CONFIDENCE ON STORM WARNINGS
FOR THE SOUTHEAST OUTERMOST WATERS. ANTICIPATING GUSTS AROUND 40 TO
45 KTS INITIALLY...SLOWLY DIMINISHING THROUGH THE PERIOD. CHANCE OF
FREEZING SPRAY FOR THE ENTIRE PERIOD. SEAS INITIALLY AROUND 12 FEET
ON THE OUTER WATERS THROUGH MONDAY...DIMINISHING MONDAY NIGHT.
TUESDAY INTO TUESDAY NIGHT...MODERATE CONFIDENCE.
COLD FRONT SLIDES ACROSS THE WATERS TUESDAY EVENING ALONG AND AHEAD
OF WHICH SOUTHWESTERLY WINDS WILL GUST IN EXCESS OF 25 KTS. WHILE
THERE MAY BE AN INITIAL LULL IN THE SEAS MONDAY NIGHT INTO
TUESDAY...ANTICIPATING SEAS OF 5 TO 7 FEET ACROSS THE OUTER WATERS
IN RESPONSE TO THE ENHANCED SOUTHERLY WINDS.
WEDNESDAY INTO THURSDAY...MODERATE CONFIDENCE.
WINDS BACKING OUT OF THE WEST-NORTHWEST IN WAKE OF A COLD FRONT.
ANTICIPATING GALE FORCE WINDS OVER ALL WATERS FOR THE PERIOD. SEAS
BUILDING TO AROUND 8 TO 10 FEET FOR WEDNESDAY NIGHT INTO LATE
THURSDAY BEFORE DIMINISHING THURSDAY NIGHT.
