AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
1250 AM EST WED JAN 21 2015

.SYNOPSIS...
DRY AND SEASONABLY COLD WEATHER THROUGH WEDNESDAY. LOW PRES
PASSING WELL SOUTH OF NEW ENGLAND WED NIGHT INTO THU MAY BRING A
PERIOD OF LIGHT SNOW SHOWERS/FLURRIES. HIGH PRESSURE WILL BUILD
INTO THE REGION THU NIGHT AND FRI BRINGING MORE DRY...SEASONABLE
CONDITIONS. LOW PRESSURE WILL MOVE UP THE EASTERN SEABOARD...
PASSING WELL SOUTHEAST OF NANTUCKET SATURDAY NIGHT INTO SUNDAY
MORNING...POSSIBLY BRINGING SOME LIGHT SNOW ACCUMULATIONS. HIGH
PRESSURE RETURNS EARLY NEXT WEEK. ANOTHER LOW MAY APPROACH AROUND
TUESDAY...THOUGH TIMING AND INTENSITY ARE UNCERTAIN.

&&

.NEAR TERM /THROUGH TODAY/...

100 AM UPDATE...

CURRENT TRENDS IN THE FORECAST REMAIN ON TRACK FOR THE OVERNIGHT
HOUR. HIGH PRESSURE EAST OF THE GREAT LAKES WILL CONTINUE TO BUILD
ACROSS THE REGION. STILL ENOUGH MOISTURE IN THE DEPARTING
SHORTWAVE TO ALLOW FOR HIGH LEVEL CLOUDS TO CONTINUE. THIS HAS
SLOWED TEMPS FROM RADIATING OUT. HOWEVER UPSTREAM SEE CLEAR SKIES
SO ONCE CLOUDS MOVE OFFSHORE...TEMPS WILL PLUMMENT AS WINDS ARE
LIGHT ACROSS THE INTERIOR. COLD AIR OVER THE RELATIVELY WARM WATER
HAS ALLOWED FOR GUSTS TO REMAIN UP ALONG THE COASTAL REGION.
EXPECT THIS CONTINUE FOR ANOTHER HOUR OR TWO.

TODAY...

HIGH PRESSURE WILL CONTINUE TO BUILD NORTH OF THE REGION TODAY
KEEPING THE INTERIOR DRY. ATTENTION THEN TURNS TO THE CLIPPER
SYSTEM DIVING INTO THE MIDWEST. THIS CLIPPER TRANSFERS ITS ENERGY
OFFSHORE TO A SECONDARY SFC LOW OFF THE MID ATLANTIC COAST. THIS
LOW WILL DEVELOP BRINGING AN INCREASE OF MOISTURE INTO THE
REGION. ANTICIPATE CLOUDS TO INCREASE THROUGHOUT THE DAY AND
NORTHERLY WINDS TO A MORE EASTERLY FLOW. WITH THE COLD AIR MOVING
OVER THE WATERS AND THE NORTHERLY FLOW DURING THE DAY...COULD SEE
SOME SNOW SHOWERS DEVELOP OVER THE WATERS. DELTA TEMP UP TO 700MB IS
CLOSE TO 17C. AS THE FLOW MOVES EASTWARD...COULD SEE THE SNOW MOVE
ONSHORE AHEAD OF THE APPROACHING SYSTEM. TIMING WILL BE CLOSER TO
EVENING. OTHERWISE TEMPS WILL BE COOLER THAN YESTERDAY WITH
DIURNAL HEATING LIMITED.

&&

.SHORT TERM /TONIGHT THROUGH 6 PM THURSDAY/...
WEDNESDAY NIGHT...LOW PRESSURE MOVES NORTHEASTWARD FROM THE VIRGINIA
COAST...PASSING WELL SOUTHEAST OF NANTUCKET BY THURSDAY MORNING.
THIS WILL BRING A PERIOD OF LIGHT SNOW TO AT LEAST THE SOUTH
COAST...CAPE...AND ISLANDS.  EXPECT A COATING UP TO ABOUT AN INCH OF
SNOW.  THERE IS A POSSIBILITY THAT AN INVERTED TROUGH
DEVELOPS...EXTENDING FROM THE LOW PRESSURE INTO SOUTHERN NEW
ENGLAND.  THIS WOULD BRING FLURRIES AND LIGHT SNOW FARTHER INTO THE
REGION THAN CURRENTLY FORECAST.  STILL WOULD NOT EXPECT ANY MORE
THAN A COATING OF SNOW.

THURSDAY...SNOW COMES TO AN END QUICKLY THURSDAY MORNING AS THE LOW
MOVES INTO THE MARITIMES AND HIGH PRESSURE STARTS TO BUILD IN.
TEMPERATURES SHOULD GET INTO THE LOW TO MID 30S BY MIDDAY.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
HIGHLIGHTS...

* LOW PRESSURE PASSING SE OF THE REGION MAY BRING LIGHT RAIN
  AND/OR SNOW SATURDAY NIGHT INTO EARLY SUNDAY
* DRY AND SEASONABLY CHILLY WEATHER SUNDAY INTO MONDAY
* HIGH UNCERTAINTY ON ANOTHER LOW POSSIBLY EFFECTING REGION LATE
  MONDAY INTO NEXT TUESDAY

DETAILS...

THURSDAY NIGHT AND FRIDAY...
HIGH PRESSURE RIDGE BUILDS NE INTO THE REGION THU NIGHT...THEN
PUSHES OFFSHORE FRIDAY. THIS WILL BRING MORE DRY CONDITIONS. WINDS
SHIFT TO SW DURING FRIDAY...SO MAY SEE TEMPS REACH CLOSE TO
SEASONABLE READINGS. HIGHS WILL BE MAINLY IN THE 30S.

FRIDAY NIGHT AND SATURDAY...
AS THE HIGH SHIFTS E FRIDAY NIGHT...MAY START TO SEE CLOUDS
INCREASE. 12Z MODELS AND ENSEMBLES CONTINUE TO SIGNAL LOW PRES
DEVELOPING ACROSS THE GULF OF MEXICO FRI NIGHT...THEN TRYING TO
RUN UP THE EASTERN SEABOARD DURING SATURDAY. AT THIS POINT...LOOKS
LIKE THE BULK OF ANY PRECIP WILL REMAIN S OF THE REGION UNTIL
SATURDAY NIGHT.

SATURDAY NIGHT INTO EARLY SUNDAY...
12Z MODEL SUITE HAS BROUGHT THE DEVELOPING COASTAL LOW CLOSER TO
THE COAST DURING THIS TIMEFRAME. ONE OPERATIONAL MODEL /CANADIAN
GGEM/ WAS SOMEWHAT OF AN OUTLIER IN KEEPING THIS LOW FURTHER
OFFSHORE. THIS LOW DOES INTENSIFY QUICKLY AS IT MOVES OFF THE
OUTER BANKS SAT AFTERNOON/EVENING...BUT QUESTION IS HOW CLOSE WILL
IT COME TO THE COAST. RIGHT NOW...LOOKS LIKE THE LOW PASSES JUST
SE OF THE 40N/70W BENCHMARK...WITH A RATHER SHARP NORTH EDGE TO
PRECIP SHIELD AS WELL. DOES LOOK LIKE A DECENT SHOT OF PRECIP
MAINLY S OF THE MASS PIKE BUT COULD ALSO REACH INTO NE COASTAL
MASS AS WELL. CURRENT QPF SUGGESTS NO MORE THAN 0.5 INCHES...
HIGHEST OVER THE CAPE AND ISLANDS WHERE PRECIP WILL BE MAINLY RAIN
TO START THEN CHANGE TO SNOW BEFORE ENDING.

AT THIS POINT...LOOKS LIKE LIGHT RAIN AND/OR SNOW TO START SAT
NIGHT...THEN CHANGING OVER TO SNOW AS COLDER AIR WORKS IN ON
BACKSIDE OF EXITING LOW SUN MORNING. FOR NOW...GOING WITH GLANCING
BLOW BUT WILL CONTINUE TO MONITOR THIS LOW/S TRACK AND INTENSITY
CLOSELY.

LATE SUNDAY AND SUNDAY NIGHT...
AS THE LOW EXITS...HIGH PRES RETURNS WITH MORE DRY CONDITIONS BUT
COOLER THAN NORMAL TEMPS.

MONDAY AND TUESDAY...
VERY LOW CONFIDENCE DURING THIS TIMEFRAME. OPERATIONAL MODELS
HAVING DIFFICULTY WITH DEVELOPMENT OF LONG WAVE TROUGHING ACROSS
THE EASTERN HALF OF THE COUNTRY...WITH THE POSSIBILITY OF A CUTOFF
UPPER LOW. NOTING THAT THE ECMWF IS MORE AGGRESSIVE WITH THIS
DIGGING...WHILE THE GFS MORE PROGRESSIVE. HOWEVER...ALSO NOTING
ANOTHER LOW TRYING TO DEVELOP AS IT MOVES OUT OF THE UPPER
PLAINS...WHICH LOOKS TO REACH THE MID ATLC COAST LATE MON. A LOT
OF QUESTIONS ON THIS SURFACE DEVELOPMENT AND POTENTIAL IMPACTS
ACROSS THE REGION. DID MENTION ONLY SLIGHT CHANCE TO CHANCE POPS
FOR PORTIONS OF THE REGION AT THIS POINT...THOUGH COULD BE A MISS
TOO.

&&

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
FORECASTER CONFIDENCE LEVELS...

LOW...LESS THAN 30 PERCENT.
MODERATE...30 TO 60 PERCENT.
HIGH...GREATER THAN 60 PERCENT.

.SHORT TERM /THROUGH THURSDAY/...

BEFORE 00Z...HIGH CONFIDENCE. VFR.

TODAY...HIGH CONFIDENCE. VFR. INCREASING CLOUD COVER FROM SW TO
NE. ONSHORE FLOW COULD DROP CIGS TO MVFR ACROSS THE CAPE AND
ISLANDS AFTER 18Z.

TONIGHT AND TOMORROW...MODERATE CONFIDENCE. PERIOD OF MVFR
CIGS/VSBYS POSSIBLE IN LOW CLOUDS SOUTH OF A LINE FROM KFIT-KBDL.
IFR CONDITIONS POSSIBLE ACROSS THE CAPE AND ISLANDS IN HEAVY SNOW
SHOWERS. CONDITIONS IMPROVING BY 18Z THURS. GUSTY NORTHERLY WINDS
UP TO 25 KTS ALONG THE EAST COASTLINE.

KBOS TAF...HIGH CONFIDENCE IN TAF. LOW CONFIDENCE ON MVFR TIMING.

KBDL TAF...HIGH CONFIDENCE IN TAF.

OUTLOOK /THURSDAY NIGHT THROUGH SUNDAY/...

FRIDAY AND FRIDAY NIGHT...HIGH CONFIDENCE. VFR CONDITIONS.

SATURDAY...LOW TO MODERATE CONFIDENCE. MAINLY VFR CONDITIONS
SAT MORNING...THEN LOW END VFR OR MVFR CIGS/VSBYS MOVE IN FROM
S-N BEGINNING ALONG S COAST MIDDAY SAT AS LOW PRES APPROACHES.

SATURDAY NIGHT AND SUNDAY...LOW CONFIDENCE. WILL LIKELY SEE
MVFR CONDITIONS...WITH PERIODS OF IFR IN RAIN AND/OR SNOW.
LOWER CONDITIONS GENERALLY S OF THE MASS PIKE...BUT DEPENDENT
UPON TRACK OF LOW PRES PASSING SE OF NANTUCKET.

&&

.MARINE...
FORECASTER CONFIDENCE LEVELS...

LOW...LESS THAN 30 PERCENT.
MODERATE...30 TO 60 PERCENT.
HIGH...GREATER THAN 60 PERCENT.

.SHORT TERM /THROUGH THURSDAY/...HIGH CONFIDENCE.

EXPECT SMALL CRAFT ADVISORIES TO LOWER AS WINDS AND SEAS SUBSIDE
EARLY TONIGHT. MAY LINGER THROUGH MOST OF THE NIGHT ACROSS THE
EASTERN OUTER WATERS THOUGH.

WILL SEE FAIRLY QUIET SEAS AND WINDS ON WEDNESDAY. LOW PRESSURE
PASSES WELL SOUTHEAST OF NANTUCKET WEDNESDAY NIGHT AND
THURSDAY...BUT SHOULD HAVE LITTLE EFFECT ON THE WINDS AND SEAS
OUTSIDE OF SOME LIGHT SNOW SHOWERS.

OUTLOOK /THURSDAY NIGHT THROUGH SUNDAY/...

THURSDAY NIGHT AND FRIDAY...MODERATE TO HIGH CONFIDENCE.
LEFTOVER SEAS AROUND 5 FT ON THE OUTER WATERS THURSDAY
NIGHT...OTHERWISE EXPECT NW WINDS GUSTING UP TO 20 KT THROUGH
MIDDAY FRIDAY...THEN DIMINISHING.

FRIDAY NIGHT AND SATURDAY...MODERATE CONFIDENCE.
EXPECT W-NW WINDS GUSTING UP TO 20 KT...MAINLY AFTER MIDNIGHT
FRIDAY. SEAS UP TO AROUND 5 FT ON THE OUTER WATERS. RAIN AND/OR
SNOW MAY DEVELOP LATER SATURDAY.

SATURDAY NIGHT AND SUNDAY...LOW CONFIDENCE.
WINDS/SEAS WILL DEPEND UPON STRENGTHENING LOW PRES AS IT TRACKS
NEAR OR SOUTH OF THE 40N/70W BENCHMARK. FOR NOW...LOOKS LIKE
NORTHERLY WINDS GUSTING UP TO SMALL CRAFT LEVELS WITH BUILDING
SEAS. LOW PROB OF GALE FORCE GUSTS.
