AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
525 AM EST THU JAN 6 2011

.SYNOPSIS...
WEAK HIGH PRESSURE WILL RESULT IN ONE MORE DRY AND COLD DAY ACROSS
SOUTHERN NEW ENGLAND TODAY. THE POTENTIAL CONTINUES FOR A MODERATE
TO LOCALIZED HEAVY SNOWFALL LATE FRIDAY INTO SATURDAY. HOWEVER...
CONFIDENCE ON SNOWFALL LOCATIONS AND DETAILS REMAINS LOW. DRY AND
SEASONABLY COLD WEATHER SHOULD RETURN TO THE REGION SUNDAY AND
MONDAY. THERE IS THE RISK FOR ANOTHER LOW DEVELOPING OFF THE EASTERN
SEABOARD TUESDAY AND/OR WEDNESDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
PARTLY SUNNY SKIES THIS MORNING SHOULD GIVE WAY TO MOSTLY CLOUDY
SKIES BY AFTERNOON.  THIS AS MID/HIGH LEVEL MOISTURE STREAM OUT
AHEAD OF A STRONG SHORTWAVE DIVING SOUTHEAST TOWARDS THE GREAT
LAKES.  HOWEVER...DRY BOUNDARY LAYER AND LACK OF FORCING WILL KEEP
THE WEATHER DRY TODAY.

A WEAK RIDGE OF HIGH PRESSURE SHOULD KEEP THE WINDS LIGHT AND LIMIT
MIXING.  THIS WILL RESULT IN HIGH/S A FEW DEGREES COLDER THAN
YESTERDAY.  HIGH/S SHOULD RANGE FROM THE UPPER 20S TO LOWER 30S
ACROSS THE INTERIOR HIGH TERRAIN...TO THE LOWER TO MIDDLE 30S
ELSEWHERE.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...
TONIGHT...
A MOSTLY CLOUDY AND COLD NIGHT IS ON TAP FOR MOST OF SOUTHERN NEW
ENGLAND.  LIGHT EASTERLY FLOW WILL GRADUALLY CAUSE CLOUDS TO LOWER
AND THICKEN...BUT MOST OF THE FORCING/DYNAMICS FOR PRECIPITATION
SHOULD REMAIN TO OUR WEST MOST OF THE NIGHT.  HOWEVER...WE MAY SEE
SOME SPOTTY LIGHT SNOW BREAK OUT TOWARDS 12Z FRIDAY ACROSS OUR
WESTERN ZONES WITH THE BEST CHANCE ACROSS THE EAST SLOPES OF THE
BERKSHIRES.  WE MAY ALSO SEE SOME OCEAN EFFECT SNOW FLURRIES BREAK
OUT ACROSS NORTHEAST MA TOWARD/S DAYBREAK.  OTHERWISE...GENERALLY A
DRY NIGHT WITH CLOUD COVER HOLDING OVERNIGHT LOWS MAINLY BETWEEN 20
AND 25.

FRIDAY...
A RATHER COMPLEX SITUATION WILL BEGIN TO UNFOLD ACROSS SOUTHERN NEW
ENGLAND.  THE INITIAL LOW PRESSURE SYSTEM WILL LIFT NORTH WELL TO
THE EAST OF SOUTHERN NEW ENGLAND.  AT THE SAME TIME...VERY STRONG
UPPER LEVEL ENERGY WILL CAUSE AN INVERTED TROUGH TO SETUP AND
POSSIBLY CAUSE A SECONDARY LOW PRESSURE SYSTEM TO DEVELOP CLOSER TO
THE COAST.

THE MODELS USUALLY DO NOT HANDLE THIS TYPE OF SETUP WELL EVEN IN THE
VERY SHORT TERM.  THEREFORE...FORECAST CONFIDENCE IS BELOW NORMAL.
NONETHELESS...WE ARE CONFIDENT THAT EASTERLY FLOW AT THE SURFACE AND
SOUTHERLY FLOW ALOFT SHOULD GENERATE WEAK LIFT ACROSS THE ENTIRE
REGION.  BASED ON THAT WILL RUN WITH LIKELY TO CATEGORICAL POPS
ACROSS THE REGION FOR LIGHT SNOW.

IT ALSO APPEARS THAT THROUGH SATURDAY 00Z...THE BEST FORCING AND
DYNAMICS SHOULD BE LOCATED MAINLY TO OUR SOUTH AND WEST WITH THE
INVERTED TROUGH.  THEREFORE...WE THINK MOST OF OUR REGION WILL JUST
SEE LIGHT SNOW WITH ACCUMULATIONS ON THE ORDER OF A COATING TO 1
INCH.

THERE ARE TWO EXCEPTIONS TO THIS WHERE SOME LOCALIZED AREAS COULD
SEE AT LEAST A FEW INCHES OF SNOW BY 00Z SATURDAY.  THE FIRST AREA
WILL BE ACROSS OUR FAR WESTERN ZONES...ESPECIALLY ACROSS THE EAST
SLOPES OF THE BERKSHIRES AND HIGHER TERRAIN OF HARTFORD COUNTY. THIS
AREA WILL BE CLOSEST TO WHERE THE INITIAL INVERTED TROUGH IS
EXPECTED TO SETUP AND ALSO WILL SEE SOME BENEFITS OF UPSLOPE.  THE
SECOND AREAS IS ACROSS EASTERN MA AND PARTICULARLY NORTHEAST MA.
THIS IS WHERE SOME OCEAN ENHANCEMENT WILL OCCUR WITH COLD AIR
ALOFT/NORTHEAST SURFACE WINDS.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
HIGHLIGHTS...

* THE POTENTIAL CONTINUES FOR A MODERATE TO HEAVY SNOWFALL LATE
  FRIDAY AND SATURDAY.
* TEMPERATURES SEASONABLY COLD THROUGH THE PERIOD.

FRIDAY NIGHT AND SATURDAY...THE MAJORITY OF THE 00Z MODEL SUITE
CONTINUES TO SIGNAL THE OCEAN LOW MOVING WELL SE OF NANTUCKET. FOR
THE LAST SEVERAL MODEL RUNS...A SIGNIFICANT INVERTED TROUGH...ALSO
KNOWN AS A NORLUN TROUGH...HAS BEEN SEEN EXTENDING WNW FROM THE
OCEAN LOW ACROSS LONG ISLAND AND SE NY STATE BACK TO ANOTHER LOW
OVER THE EASTERN GREAT LAKES. WITH GOOD CONVERGENCE ALONG THIS
TROUGH...A NARROW BAND OF MODERATE TO HEAVY SNOWFALL /FROM ABOUT 30
TO 60 MILES WIDE/ IS LIKELY. THE BIG QUESTION REMAINS...WHERE DOES
THIS OCCUR. THIS IS A MESOSCALE FEATURE...AND POSITIONING IS NOT
HANDLED VERY WELL BY OUR SYNOPTIC SCALE MODELS. THIS CONTINUES TO
PRESENT A BIG DILEMMA FOR OUR FORECAST DURING THIS TIMEFRAME.

SOME OF THE MODELS ARE ACTUALLY SHOWING MULTIPLE BANDS...INCLUDING A
WEAKER ONE EXTENDING ACROSS SOUTHERN NEW ENGLAND...WHILE THE
STRONGER BAND SETS UP FURTHER S AS MENTIONED ABOVE. AT THIS POINT...
THINK THERE IS MODERATE CONFIDENCE FOR AT LEAST A FEW INCHES OF SNOW
POSSIBLY TO ADVISORY LEVEL FOR LATE FRIDAY THROUGH SATURDAY FROM
BOTH THIS MULTIPLE SNOW BANDS AS WELL AS GENERAL LOW LEVEL
CONVERGENCE AND CONTINUED ONSHORE FLOW. STILL A BIT TOO SOON TO
ISSUE ADVISORIES. HOWEVER...STILL HAVE LOW CONFIDENCE FOR WINTER
STORM WATCHES OR WARNINGS AT THIS TIME.

HAVE KEPT LIKELY TO CATEGORICAL POPS GOING THROUGH FRIDAY NIGHT. THE
MODELS THEN SLOWLY PUSH THE TROUGH N DURING SATURDAY. AGAIN...THIS
TREND WILL HAVE TO BE WATCHED AS ANY SNOW BANDING COULD STALL LATE
FRIDAY NIGHT OR SATURDAY MORNING. FOR NOW...HAVE TRENDED TO TAPER
THE SNOW OFF ACROSS N CT/RI DURING THE AFTERNOON. SNOW SHOWERS MAY
LINGER ACROSS S NH/E MA INTO SATURDAY NIGHT...THEN SHOULD MOVE OUT.

TO REITERATE...STILL HAVE QUITE A BIT OF UNCERTAINTY AS TO THE
POSITIONING OF THE INVERTED TROUGH AS IT SETS UP. FEEL THERE WILL BE
LIGHT SNOW ACCUMULATIONS FOR MOST AREAS...AND POSSIBLY LOCALLY
MODERATE TO HEAVY SNOWFALL NEAR THE INVERTED TROUGH/S/. HAVE
CONTINUED TO INDICATE THE RISK FOR ACCUMULATING SNOWFALL.

SUNDAY-MONDAY...EXPECT SEASONABLY COLD AND DRY WEATHER AS THE OCEAN
LOW DEEPENS NEAR THE MARITIMES. BLUSTERY N-NW WINDS WILL BRING COLD
WIND CHILL VALUES...MAINLY DURING SUNDAY. MAY SEE LEFTOVER SNOW
SHOWERS EARLY SUNDAY ACROSS S NH/E MA.

TUESDAY-WEDNESDAY...00Z OP MODEL RUNS CONTINUE TO SHOW THE POTENTIAL
FOR COASTAL OR OCEAN LOW PRESSURE OFF THE MID ATLANTIC COAST.
HOWEVER...THEY ARE NOW SPLIT AS TO WHETHER THIS LOW MOVES HARMLESSLY
S OF THE REGION /ECMWF/ OR MAKES A RUN UP THE COAST /GFS AND GGEM/.
GFS ENSEMBLE MEANS BRING THE LOW A BIT CLOSER...BUT STILL OFFSHORE.
THIS IS STILL A WEEK AWAY...SO MUCH CAN AND WILL CHANGE. FOR NOW...
CONTINUED WITH FORECAST CONTINUITY. WENT WITH CHANCE POPS FOR MOST
AREAS FOR LATE TUESDAY THROUGH WEDNESDAY.

&&

.AVIATION /10Z THURSDAY THROUGH MONDAY/...
FORECASTER CONFIDENCE LEVELS...
  LOW...LESS THAN 30 PERCENT
  MEDIUM...30 PERCENT TO 60 PERCENT
  HIGH...GREATER THAN 60 PERCENT

TODAY...MEDIUM CONFIDENCE IN MAINLY VFR CONDITIONS.  HOWEVER...LOW
PROBABILITY OF SOME MARGINAL MVFR CEILINGS DEVELOPING DURING THE
AFTERNOON.

TONIGHT...MEDIUM CONFIDENCE IN MARGINAL MVFR CONDITIONS DEVELOPING
ACROSS A GOOD CHUNK OF THE REGION.  TIMING REMAINS UNCERTAIN...BUT
WE MAY SEE THIS FIRST ACROSS THE DISTANT INTERIOR AND ALSO ALONG THE
EASTERN MA COAST.

FRIDAY...MEDIUM TO HIGH CONFIDENCE IN MAINLY MVFR/IFR.  THIS IS FOR
LIGHT SNOW THAT IS EXPECTED TO DEVELOP ACROSS THE REGION.

KBOS TAF...MEDIUM TO HIGH CONFIDENCE IN MAINLY VFR CONDITIONS INTO
THIS AFTERNOON.  MEDIUM CONFIDENCE THAT MVFR CEILINGS DEVELOP
SOMETIME TONIGHT.  HIGH CONFIDENCE IN AT LEAST MVFR CONDITIONS ON
FRIDAY WITH PERIODS OF IFR CONDITIONS POSSIBLE IN SNOW.

OUTLOOK...FRIDAY NIGHT THROUGH MONDAY...

FRIDAY NIGHT AND SATURDAY...MVFR LIKELY IN SNOW. MEDIUM PROBABILITY
OF IFR CONDITIONS. MODERATE TO HEAVY SNOW ACCUMULATION POSSIBLE.
CONFIDENCE REMAINS LOW AS SWATH OF HEAVY SNOW WILL LIKELY BE A
NARROW BAND OF ONLY 30-60 MILES WIDE.

SUNDAY...MODERATE TO HIGH CONFIDENCE FOR VFR CONDITIONS. STRONG N-NW
WIND GUSTS POSSIBLE.

MON...MODERATE TO HIGH CONFIDENCE FOR VFR CONDITIONS ALONG WITH
BRISK NW WINDS.

&&

.MARINE...
TODAY AND TONIGHT...
WEAK RIDGE OF HIGH PRESSURE WILL KEEP WINDS AND SEAS WELL BELOW SCA
THRESHOLDS.

FRIDAY...
DEVELOPING OCEAN STORM WILL ALLOW NORTHEAST WINDS TO STRENGTHEN.
THE POTENTIAL EXISTS FOR MARGINAL AFTERNOON WIND GUSTS OF 20 TO 25
KNOTS OVER THE OPEN WATERS.  HOWEVER...SINCE ITS A LATE THIRD PERIOD
EVENT AND VERY MARGINAL WILL DEFER TO THE NEXT SHIFT FOR ANY
POSSIBLE HEADLINES.  IN ADDITION...SNOW WILL BE DEVELOPING ACROSS
THE WATERS AND REDUCE VISIBILITIES.

OUTLOOK...FRIDAY NIGHT THROUGH MONDAY...

FRIDAY NIGHT AND SATURDAY...OCEAN STORM EXPECTED TO INTENSIFY AS IT
PASSES WELL SE OF NANTUCKET. EXPECT E-NE WINDS TO START OFF FRIDAY
NIGHT...WITH SOME GUSTS UP TO 20 KT...THEN SHIFTING TO W AS AN
ASSOCIATED TROUGH MOVES N ACROSS THE WATERS SATURDAY. GUSTS UP TO
SMALL CRAFT CRITERIA POSSIBLE. VSBY MAY BE POOR IN AREAS OF MODERATE
TO HEAVY SNOW.

SUNDAY-MONDAY...THE OCEAN LOW WILL INTENSIFY TO A GALE CENTER...SO
EXPECT N-NW GALE GUSTS TO DEVELOP ACROSS THE OPEN WATERS SUNDAY AND
SUNDAY NIGHT...SLOWLY DIMINISHING MONDAY. FREEZING SPRAY POSSIBLE.

CURRENT TIMING DURING FRIDAY NIGHT AND SATURDAY. THERE IS EVEN A
LOW CHANCE OF WARNING CRITERIA SNOWFALL...DEPENDING UPON IF OR
