AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
157 PM EDT THU MAR 17 2016
.SYNOPSIS...
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS WITH GUSTY WINDS AND
SMALL HAIL WILL BE POSSIBLE BETWEEN 2 AND 8 PM. A POLAR FRONT
FRIDAY WILL BRING ANOTHER ROUND OF SCATTERED SHOWERS ALONG WITH
GUSTY WINDS AND MUCH COLDER WEATHER INTO THE WEEKEND. A STRONG
COASTAL STORM REMAINS POSSIBLE LATE SUNDAY INTO MONDAY ALONG WITH
THE POTENTIAL FOR SIGNIFICANT RAIN AND/OR SNOW.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
***SCATTERED SHOWERS/THUNDERSTORMS WITH GUSTY WINDS AND SMALL
HAIL POSSIBLE THROUGH 8 PM***
2 PM UPDATE...
LEFTOVER FOG ACROSS NANTUCKET IS EXPECTED TO DISSIPATE AND SLIP
EAST BY 4 PM. AN AREA OF SHOWERS WITH POTENTIAL FOR ISOLATED
THUNDER HAS DEVELOPED ACROSS SE MA AIDED BY SOME LOW LEVEL
CONVERGENCE. A MORE GENERAL AREA OF SCT SHOWERS AND ISOLATED TSTMS
WERE AT 145 PM APPROACHING THE BERKSHIRES. RADAR RETURNS INDICATE
THAT ENOUGH MOISTURE TO SUPPORT SCATTERED SHOWERS AS WELL AS
ISOLATED THUNDER THROUGH MUCH OF THE AREA THIS AFTERNOON.
INSTABILITY IS QUITE IMPRESSIVE WITH MID LEVEL LAPSE RATE AT OR
GREATER 8C/KM INDICATED ON SPC MESOANALYSIS PAGE ALONG WITH EVEN
500 J/KG ACROSS WEST CENTRAL AREAS. MUCH OF SOUTHERN NEW ENGLAND
IS FORECAST TO HAVE TOTAL TOTALS APPROACH...IF NOT EVEN EXCEED A
LITTLE...60 WITH A POOL OF -32C TEMPS ADVECTING INTO THE AREA.
DEEP MIXING WILL RESULT IN THE POTENTIAL FOR GUSY WINDS AND SMALL
HAIL. ISOLATED SEVERE CANNOT BE RULED OUT.
TEMPERATURE FORECAST LOOKS FAIRLY GOOD. WILL BE ADJUSTING POPS TO
BE CONSISTENT WITH RADAR TRENDS DURING THE AFTERNOON.
11 AM UPDATE...
AS OF 11 AM...FOG HAD ERODED EVERYWHERE EXCEPT CAPE COD...MARTHAS
VINEYARD...AND NANTUCKET. IT SHOULD CLEAR UP THERE IN THE NEXT
HOUR OR TWO. SUNSHINE WAS THE RULE ACROSS MOST OF THE REGION AND
AS A RESULT...TEMPERATURES WERE ZOOMING INTO THE 50S. WINDS WERE
BEGINNING TO GUST TO 10 TO 20 MPH. HAVE NOT MADE ANY CHANGES TO
THE HIGH TEMPERATURE OR WIND FORECASTS FOR THIS AFTERNOON.
EXPECTING SURFACE TEMPERATURES TO REACH 60 TO 65 AWAY FROM THE
COAST AND WINDS TO GUST TO 20 TO 30 MPH AT TIMES.
THE MAIN CONCERN FOR THE AFTERNOON IS THE FACT THAT THE AIR AT 500
MB...OR 18000 FT...IS -32C. THAT WILL MAKE FOR VERY UNSTABLE
CONDITIONS. DESPITE DRIER DEWPOINTS MIXING DOWN FROM ALOFT...THE
MESOSCALE MODELS ARE FORECASTING THE RAPID DEVELOPMENT OF SHOWERS
BY 17Z OR 1 PM...INCREASING IN COVERAGE AND SPREADING
EASTWARD...THEN EXITING THE COAST BY 23Z/7 PM. A FEW THUNDERSTORMS
ARE EXPECTED. ANY SHOWERS OR THUNDERSTORMS COULD PRODUCE HAIL UP
TO THE SIZE OF DIMES OR NICKELS THIS AFTERNOON DUE TO THE COLD
AIR ALOFT AND MIX DOWN ISOLATED BRIEF WIND GUSTS TO 40 TO 50 MPH.
THE MESOSCALE ANALYSIS PAGE FROM SPC SHOWS 250-500 JOULES/KG OF
CAPE ACROSS THE REGION THIS AFTERNOON.THE STORM PREDICTION CENTER
HAS PORTIONS OF MASSACHUSETTS IN A MARGINAL RISK FOR SEVERE
THUNDERSTORM ACTIVITY...WHICH WOULD MEAN QUARTER SIZE HAIL OR
GUSTS TO 58 MPH. WE ARE EXPECTING MOST ACTIVITY TO REMAIN BELOW
THESE THRESHOLDS.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM FRIDAY/...
THE BULK OF THE SHOWERS/ISOLATED THUNDERSTORMS SHOULD COME TO AN
END BY LATE EVENING. MAINLY DRY WEATHER EXPECTED FOR THE REST OF
THE NIGHT OTHER THAN A FEW PASSING RAIN/SNOW SHOWERS ALONG THE
EAST SLOPES OF THE BERKSHIRES. LOW TEMPS WILL MAINLY BE IN THE
UPPER 30S TO THE LOWER 40S.
&&
.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
UPDATED 415 PM
HIGHLIGHTS...
* POLAR FRONT FRI BRINGS SCATTERED RAIN SHOWERS/SQUALLS
* EXTENDED PERIOD OF CHILLY TEMPERATURES FRI NIGHT THRU TUESDAY
* DRY WEATHER FRI NIGHT INTO EARLY SUNDAY
* SIGNIFICANT COASTAL STORM REMAINS POSSIBLE LATE SUNDAY INTO MON
WITH POTENTIAL HEAVY RAIN AND/OR SNOW
OVERVIEW AND MODEL PREFERENCES...
A COMPLEX PATTERN WITH NEAR NEUTRAL TELECONNECTIONS DEFINES THE
MEDIUM RANGE OF THE UPCOMING FORECAST. HOWEVER...ONE COMPONENT
REMAINS PERSISTENT...THAT A CONDUIT FOR COLD AIR DIRECT FROM
HUDSON BAY WILL SPILL INTO THE NE CONUS THROUGH THE WEEKEND. THIS
WILL IMPACT SENSIBLE WX...ANOTHER ROUND OF SHOWERS/SQUALLS
POSSIBLE FOR FRI...COOL TEMPS FOR THE WEEKEND...AND THE COASTAL
STORM WE CONTINUE TO MONITOR SUNDAY NIGHT INTO MON. THEREAFTER...A
ZONAL FLOW PATTERN DEVELOPS...FORCING THE COLD AIR BACK TO THE N.
REGARDING THE POTENTIAL COASTAL STORM. STILL TOO MUCH UNCERTAINTY
TO LEAN DIRECTLY ON ANY ONE TRACK. IN FACT 17.00Z CMC/GFS ARE
PERFECT EXAMPLES OF WHAT COULD HAPPEN IF NO PHASING OCCURS...A
FAST MOVING...AND NOT VERY DEEP RESULTANT LOW PRES. THE
ECMWF/UKMET AND SOME GEFS/ECENS ENSEMBLES ALLOW FOR PHASING OF A
TRAILING ARCTIC WAVE...NEGATIVELY TILTING THE TROUGH...ENHANCING
CYCLOGENESIS AND PULLING THE SYSTEM FURTHER NW. COMPLICATING THE
MATTER IS A MEANDERING BLOCK ACROSS SRN CANADA/NRN PLAINS THAT
COULD SPEED UP/SLOW DOWN THE INITIAL SHORTWAVE MOVING OUT OF THE
PACIFIC. UNTIL THESE FEATURES ARE BETTER RESOLVED...A BLEND OF
AVAILABLE GUIDANCE...WITH MORE WEIGHT ON ENSEMBLES IS FAVORED WITH
THIS UPDATE.
DETAILS...
FRI AND FRI NIGHT...
COLD FRONT WILL CROSS THE REGION LATE FRI. THIS WITHIN A REGIME
OF H5 TEMPS BELOW -30C. CONVERGENCE OF MODEST MOISTURE WILL LEAD
TO SOME SHRA DEVELOPMENT. INVERTED-V PROFILE APPARENT ON BUFKIT
WITH MIXING NOT QUITE AS DEEP AS THU...BUT ENOUGH TO MIX DOWN
30-40 KT MOMENTUM. THEREFORE..ANOTHER RISK FOR SQUALLS WITH SMALL
HAIL/WIND POSSIBLE. IN FACT...IF DYNAMIC COOLING IS STRONG ENOUGH
CHANGE TO SNOW IS POSSIBLE IN SPITE OF SFC TEMPS IN THE 40S AND
50S. BEHIND THE FRONT...STRONG PRES RISES COULD CONTINUE TO
SUPPORT GUSTY WINDS INTO THE OVERNIGHT HOURS...WITH 30-40 MPH
GUSTS POSSIBLE. AMBIENT TEMPS WILL FALL BACK INTO THE 20S...SO
EXPECT WIND CHILLS AS LOW AS THE SINGLE DIGITS. GIVEN THE RISK OF
MIXING TO NEAR 40 KT...A WIND ADVISORY MAY NEED TO BE CONSIDERED.
SAT AND SUN...
HIGH PRES BUILDS ACROSS QUEBEC AND NRN NEW ENGLAND WITH TEMPS
MUCH COOLER THAN LAST. H92 TEMPS SETTLE TO AROUND -4C SAT... AND
-6C ON SUN. THEREFORE...IN SPITE OF THE EXPECTED SUNSHINE...HIGHS
ON THE THE LOW-MID 40S AND LOWS IN THE UPPER TEENS AND 20S ARE
EXPECTED. WHILE THIS IS ACTUALLY STILL CLOSER TO SEASONAL
NORMALS...IT WILL FEEL COLD IN COMPARISON TO LAST WEEKEND
ESPECIALLY.
SUN NIGHT INTO MON...
POTENTIAL COASTAL STORM CONTINUES TO HIGHLIGHT THE MEDIUM RANGE
FORECAST. WHILE WE MIGHT ALL LIKE TO SAY...HERE ARE THE ANSWERS...
IT IS STILL JUST TOO SOON TO NAIL DOWN EXACT SENSIBLE WX DETAILS
AS THE SHORTWAVE ENERGY HAS YET TO BE FULLY SAMPLED BY ONSHORE
REMOTE SENSING NETWORK...AND MODELS CONTINUE TO STRUGGLE WITH THE
BLOCK ACROSS THE NRN CONUS AND SRN CANADIAN PRAIRIE. THE FASTER
CMC/GFS SOLUTION WOULD PRODUCE LESS OVERALL QPF...EVEN THOUGH
THEIR CURRENT PATH IS NEAR OR JUST INSIDE THE 40/70
BENCHMARK...MAINLY BECAUSE THE TROWAL/F-GEN DYNAMICS ARE NOT AS
STRONG. MEANWHILE...THE ECMWF/UKMET ARE STRONGER...BUT POTENTIALLY
TOO CLOSE..FOR THE ERN HALF OF THE REGION. GIVEN THESE
UNCERTAINTIES...AND UNTIL THE PHASING/LACK THEREOF CAN BE BETTER
RESOLVED...HERE ARE THE POTENTIAL IMPACTS.
SNOW/RAINFALL...
A CLOSER PASS MEANS INCREASED RISK FOR OVERALL PRECIPITATION...
HOWEVER IT WOULD INTRODUCE A HIGHER RISK FOR RAIN FOR PORTIONS OF
EASTERN MA...PARTICULARLY THE CAPE/ISLANDS. SHOULD THE LOW PASS
INLAND...HEAVY RAINFALL AND THERE IS AN INCREASED RISK FOR
URBAN/SMALL STREAM FLOODING. A PASS OUT TO SEA...BUT CLOSE ENOUGH
TO THE BENCHMARK...SUGGESTS HIGHER RISK FOR SNOWFALL EVERYWHERE
AS THE H92 0C LINE WOULD REMAIN WELL OFFSHORE AS WELL. IN ANY
SOLUTION...THE SNOWFALL COULD BE RELATIVELY LOW RATIO...HEAVY AND
WET ESPECIALLY CLOSER TO THE COASTLINES...AND WOULD BE PLOWABLE IN
TOTAL AMOUNTS...WITH HIGHER AMOUNTS FARTHER INLAND THANKS TO A
BENT BACK WARM FRONT. AT THIS TIME...QPF TOTALS GENERALLY RANGE
FROM 0.5 INCHES TO AS MUCH AS 1.25.
WINDS...
TYPICAL NOR-EASTER WIND DIRECTION...BUT THE WIND RADII AND
STRENGTH WILL ALSO DEPEND ON TRACK. THERE IS THE RISK FOR STRONG
WINDS AS CURRENT PROJECTS SUGGEST H92 WINDS OF 50 KT AVAILABLE.
WHILE THIS IS MOST LIKELY FOR THE CAPE/ISLANDS...COINCIDENT WITH
THE HIGHEST RISK FOR WET SNOW...AND SHIFT FARTHER INLAND MEANS
THE REST OF MA/RI/CT COULD SEE STRONG WINDS ALONG WITH THE WET
SNOW.
COASTAL FLOODING...
SUN NIGHT THROUGH MON EVENING HIGH TIDES ON THE EAST COAST
/BOSTON/ ARE AROUND 10 FT. NOT ASTRONOMICALLY HIGH. THEREFORE...TO
PRODUCE SURGE/WAVE ACTION HIGH ENOUGH TO PROMOTE A RISK FOR
COASTAL FLOODING WOULD REQUIRE A PASSAGE CURRENTLY PROJECTED BY
THE ECMWF/UKMET. IN ESSENCE A STRONGER/CLOSER PASS...AND EVEN THAT
MAY NOT QUITE MAKE IT GIVEN THE 2.0+ FT SURGE IT WOULD REQUIRE TO
REACH MINOR LEVELS. THE GFS/CMC WOULD BE TOO PROGRESSIVE.
THEREFORE..IT IS A RELATIVELY LOW RISK AT THIS TIME BUT WILL BE
WORTH WATCHING ONCE THE TRACK IS BETTER AGREED UPON.
MON NIGHT INTO TUE...
STRONG NW FLOW FOLLOWS THE LOW PRES PASSAGE REGARDLESS OF THE
TRACK. A BRIEF COOL DOWN WITH COLD WINDCHILLS FOLLOWS.
WED AND THU...
ZONAL FLOW WITH SEVERAL WEAKER SHORTWAVES SUGGEST THE RATHER
ACTIVE PATTERN CONTINUES. HOWEVER...SLIGHT TRAJECTORY SHIFT LOOKS
TO ALLOW MILD TEMPS TO ONCE AGAIN RETURN.
