Area forecast discussion, Dec 16, 4:50 PM EST, 2 hours 26 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
450 PM EST SUN DEC 16 2012
.SYNOPSIS...
A WEAK LOW PRESSURE SYSTEM WILL BRING A WINTRY MIX OF
PRECIPITATION TO THE REGION TONIGHT. A SECONDARY LOW PRESSURE WILL
DEVELOP SOUTH OF LONG ISLAND MONDAY NIGHT...THEN WILL SHIFT NE
DURING TUESDAY. WEAK HIGH PRESSURE WILL MOVE ACROSS THE REGION
WEDNESDAY INTO THURSDAY...THEN ANOTHER FRONT WILL APPROACH LATE
THIS WEEK. SOME PRECIPITATION MAY LINGER INTO NEXT WEEKEND WITH
COLDER AIR MOVING IN.
&&
.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
PRECIPITATION NOW STARTING TO BLOSSOM ALONG THE SOUTH COAST.
RECENT OBSERVATIONS SHOWING WARM AIR TRYING TO OVERSPREAD
SOUTHERN NEW ENGLAND. COLD AIR DAMMING IN THE WORCESTER HILLS
NORTH OF A COASTAL FRONT HAS GENERATED NORTH WINDS...WHICH WILL
ONLY SERVE TO ENHANCE THIS FRONT. WORCESTER HAS SWITCHED TO
FREEZING RAIN THIS PAST HOUR WITH TEMPERATURES WELL BELOW
FREEZING. THIS IS A TESTAMENT TO THE STRENGTH OF THE WARM AIR
TRYING TO MOVE NORTH.
STILL EXPECTING A LOW PRESSURE TO MOVE EAST JUST TO THE SOUTH OF
NEW ENGLAND OVERNIGHT. GENERALLY FAVORED A CONSENSUS TIMING
OVERNIGHT. THE BIG QUESTION WILL BE THE THERMAL STRUCTURE. LOOKS
LIKE THERE WILL BE PLENTY OF LIFT WITHIN THE DENDRITIC SNOW GROWTH
REGION...BUT NOT MUCH MOISTURE. THUS NOT THINKING THERE WILL BE
COPIOUS AMOUNTS OF SNOW. THE REPORTS OF SLEET AND SNOW DO INDICATE
THE PRESENCE OF ACTIVE ICE NUCLEI THIS AFTERNOON.
THE QUESTION THEN BECOMES HOW QUICKLY THE WARM AIR PUSHES NORTH.
ONCE WE GET PAST THE INITIAL WET-BULBING THIS AFTERNOON AND
EVENING...AM EXPECTING TEMPERATURES TO RISE SLOWLY OR REMAIN
STEADY OVERNIGHT. THIS MAINTAINS THE POSSIBILITY OF FREEZING RAIN
FOR AT LEAST PORTIONS OF SOUTHERN NEW ENGLAND THROUGH TONIGHT.
BASED ON CURRENT REPORTS...AND EXPECTED PRECIPITATION TYPE...
EXPANDED THE WINTER WEATHER ADVISORY FOR FREEZING RAIN INTO
PORTIONS OF MIDDLESEX AND ESSEX COUNTIES.
&&
.SHORT TERM /6 AM MONDAY MORNING THROUGH 6 PM MONDAY/...
SURFACE LOW PRESSURE DEPARTS OFF TO THE EAST DURING THE
MORNING...BUT WILL STILL HAVE TO CONTEND WITH A DECENT MID-LEVEL
SHORTWAVE. THINKING PRECIPITATION WILL STILL BE MORE SHOWERY THAN
STRATIFORM. POTENTIAL FOR SHOWERS SHOULD LINGER THOUGH THE
DAY...BUT DEFINITELY NOT EXPECTING A WASHOUT. TEMPERATURES AT THIS
POINT SHOULD BE SUFFICIENTLY HIGH FOR ALL RAIN...EXCEPT FOR
PORTIONS OF SOUTHERN NH WHERE A WINTRY MIX COULD LINGER INTO THE
EARLY AFTERNOON AT ELEVATIONS ABOVE 1500 FT.
&&
.LONG TERM /MONDAY NIGHT THROUGH SUNDAY/...
MODEL DISCUSSION AND PREFERENCES...
MEDIUM RANGE MODEL SUITE IN FAIRLY GOOD AGREEMENT DURING THE EARLY
PORTION OF THIS FORECAST PERIOD...FROM MON NIGHT THROUGH ABOUT
THURSDAY...THEN MODELS START TO DIVERGE ON APPROACH OF NEXT SYSTEM
AS IT MOVES OUT OF THE MIDWEST TOWARD THE REGION LATE IN THE WEEK.
WHEN LOOKING AT THE ENSEMBLES...THOUGH...LOOKS LIKE THERE IS A BIT
BETTER CONTINUITY INTO NEXT WEEKEND. STILL NOTING A GENERAL
AMPLIFIED THOUGH PROGRESSIVE FLOW ACROSS THE NORTHERN TIER STATES
WITH GENERAL TROUGHING ACROSS THE NORTHEAST EXCEPT FOR THE LATE WED-
THU TIMEFRAME WITH WEAK RIDGING MOVING ACROSS. BIGGEST QUESTIONS AT
THIS POINT ARE DURING THE EARLY PORTION /MON NIGHT-EARLY WED/ THEN
INTO NEXT WEEKEND TIMEFRAMES...MAINLY FOR TIMING ISSUES ESPECIALLY
FOR THE THU NIGHT INTO FRI NIGHT SYSTEM.
APPEARS THAT THE NAM/ECMWF WERE IN PRETTY GOOD AGREEMENT FOR THE
EARLY PORTION OF THE FORECAST...GFS DID NOT APPEAR TO HANDLE TO
SECONDARY DEVELOPMENT S OF LONG ISLAND TOO WELL. THE GFS ALSO
APPEARS A BIT TOO FAST WITH THE MOVEMENT OF THE NEXT N-S ORIENTED
FRONT MOVING OUT OF THE MIDWEST...WHILE THE ECMWF AND GGEM HAVE GOOD
AGREEMENT SO LEANED TOWARD THE TIMING OF THOSE MODELS FOR THU NIGHT-
FRI NIGHT.
DETAILS...
MONDAY NIGHT AND TUESDAY NIGHT...
LOW PRES ENERGY FROM SE NY STATE TRANSFERS TO DEVELOPING SECONDARY
LOW NEAR OR S OF LONG ISLAND MON NIGHT. NOTING ANOTHER SURGE OF LOW
LEVEL MOISTURE CONVERGENCE AS WELL AS DECENT INSTABILITY MOVING
ACROSS MAINLY CENTRAL AND SOUTHERN AREAS. WENT WITH CATEGORICAL POPS
BASED ON THIS. WILL LIKELY SEE SOME BRIEF HEAVY DOWNPOURS WHICH MAY
CAUSE URBAN AND POOR DRAINAGE FLOODING LATE MONDAY NIGHT...IN TIME
FOR THE EARLY TUE MORNING COMMUTE. AS SOME COLD AIR WORKS INTO
NORTHERN CHESHIRE/HILLSBOROUGH COUNTIES NH AS THE SYSTEM PULLS AWAY
EARLY TUE...MAY SEE POCKETS OF FREEZING RAIN AROUND SUNRISE BEFORE
TEMPS SLOWLY RISE. SOME PRECIP MAY LINGER INTO TUE NIGHT AS THE
UPPER LEVEL SYSTEM MOVES THROUGH. MAY EVEN SEE A LITTLE BIT OF SNOW
BEFORE ENDING ACROSS S NH TUE NIGHT...BUT EXPECTING ONLY LIGHT
ACCUMULATIONS.
WEDNESDAY-WEDNESDAY NIGHT...
HIGH PRES RIDGE AT THE SURFACE AND ALOFT WILL STEADILY MOVE E ACROSS
THE REGION. WHILE TEMPS ONLY FALL BACK A FEW DEGS COLDER THAN ON
TUE...NW WINDS WILL BE BLUSTERY ESPECIALLY ACROSS THE HIGHER TERRAIN
AS PRES GRADIENT INCREASES WHILE THE DEPARTING LOW PRES STRENGTHENS
OVER THE MARITIMES. SOME OF THE SUSTAINED WINDS ALONG THE S
COAST...CAPE COD AND THE ISLANDS WILL APPROACH WIND ADVISORY
CRITERIA DURING WED INTO WED NIGHT. WINDS WILL START TO SHIFT TO SE-
S WED NIGHT AS NEXT SYSTEM APPROACHES.
THURSDAY-FRIDAY...STRONG LOW PRES OVER THE GREAT LAKES WITH ITS
ASSOCIATED COLD FRONT WILL SLOWLY BUT STEADILY MOVE E. APPEARS THAT
THE LEADING EDGE OF THE PRECIP WILL MOVE INTO WESTERN AREAS DURING
THU AFTERNOON...BUT THE BULK OF THE PRECIP WILL NOT ARRIVE UNTIL THU
NIGHT. EXPECT MAINLY RAIN WITH THIS SYSTEM AS WINDS REMAIN FROM THE
S-SW...BUT TEMPS MAY GET COLD ENOUGH FOR PERIOD OF FREEZING RAIN
LATE THU NIGHT-FRI MORNING ACROSS SW NH/N CENTRAL AND W MA. WILL
CONTINUE TO MONITOR MODEL RUNS...AS THIS IS STILL SEVERAL DAYS
AWAY...FOR TIMING AND TEMP CHANGES.
SATURDAY-SUNDAY...BIG QUESTION AT THIS POINT IS WHEN THIS SYSTEM
WILL MOVE NE INTO THE MARITIMES AS LARGE HIGH PRES BUILDS OUT OF
CENTRAL CANADA AND THE PLAINS STATES. MAY SEE PERIOD OF LIGHT SNOW
AT THE TAIL END OF THIS SYSTEM...THOUGH TIMING IS STILL VERY MUCH IN
QUESTION. FOR NOW...HAVE PRECIP ENDING EARLY SAT MORNING...WITH
CLOUDS LINGERING AS WELL AS LEFTOVER SNOW SHOWERS MAINLY ACROSS S
NH/N MA INTO SAT AFTERNOON. APPEARS BATCH OF COLDER AIR WORKS IN
DURING THE WEEKEND AS WELL.

HIGH CONFIDENCE FOR MVFR INTO THIS EVENING. ISOLATED IFR CIGS IN
THE HEAVIER SNOW SHOWERS. SOME SLEET AND FREEZING RAIN LIKELY...
ESPECIALLY WHEN TRAVERSING THE LOWEST 2000 FT AGL. HIGH CONFIDENCE
IN TAF TRENDS...LOWER CONFIDENCE IN TIMING PRECIPITATION
TRANSITIONS.
KBOS TAF...MAIN CONCERN WILL BE A PERIOD OF SLEET AT THE TERMINAL

PAST 22Z.

IFR CONDITIONS IN RAIN SHOWERS AND PATCHY FOG. MAY SEE BRIEF
PERIODS OF -FZRA ACROSS HIGHER TERRAIN OF S NH BETWEEN 06Z-12Z TUE.
TUESDAY NIGHT AND WEDNESDAY...MODERATE CONFIDENCE. MVFR CEILINGS
EVENTUALLY IMPROVE TO VFR. LEFTOVER SHOWERS ACROSS E MA/S NH TUE
NIGHT/EARLY WED MAY BRING BRIEF MVFR VSBYS.
WEDNESDAY NIGHT AND THURSDAY...MODERATE CONFIDENCE. MAINLY VFR
CONDITIONS INTO THU MORNING. MAY SEE CONDITIONS LOWER TO MVFR-IFR
THU AFTERNOON AS NEXT SYSTEM APPROACHES.
THURSDAY NIGHT AND FRIDAY...LOW TO MODERATE CONFIDENCE. GENERAL MVFR
CIGS/VSBYS WITH POCKETS OF IFR IN RAIN AND PATCHY FOG. MAY SEE AREA
OF -FZRA LATE THU NIGHT-FRI MORNING ACROSS SW NH/N CENTRAL AND W MA.
&&
.MARINE...
HIGH CONFIDENCE FOR SMALL CRAFT ADVISORY CONDITIONS OUTSIDE BOSTON
HARBOR AND NARRAGANSETT BAY. LOWER CONFIDENCE FOR SOME GALE FORCE
GUSTS SOUTH AND EAST OF NANTUCKET AND CAPE COD OVERNIGHT.
VISIBILITY WILL DETERIORATE LATER THIS EVENING...AND ESPECIALLY
AFTER MIDNIGHT.
OUTLOOK...MONDAY NIGHT THROUGH FRIDAY...
MONDAY NIGHT AND TUESDAY NIGHT...HIGH CONFIDENCE IN E WINDS...SHIFTING
TO S TUE NIGHT. EXPECT GUSTS TO 25-30 KT. SEAS MAY APPROACH OR
EXCEED 10 FEET ACROSS THE EASTERN OUTER WATERS.
WEDNESDAY-WEDNESDAY NIGHT...MODERATE CONFIDENCE. PERIOD OF GALE
FORCE NORTHWEST WIND GUSTS BEHIND THE DEPARTING LOW PRESSURE SYSTEM
IS LIKELY.
THURSDAY-FRIDAY...MODERATE CONFIDENCE. WINDS AND SEAS WILL SLOWLY
DIMINISH AS PRESSURE GRADIENT WEAKENS...THOUGH BOTH WILL LIKELY
REMAIN AOA SMALL CRAFT CRITERIA.
&&
.TIDES/COASTAL FLOODING...
EASTERLY WINDS WILL BE STRONGER DURING THE HIGH TIDES MONDAY AND
TUESDAY...SO THERE IS GREATER RISK OF BEACH EROSION/MINOR COASTAL
FLOODING EVEN THOUGH ASTRONOMICAL TIDES WILL BE A BIT LOWER. WE
EVENTUALLY MAY NEED A COASTAL FLOOD ADVISORY FOR MONDAY AND/OR
TUESDAY...BUT NOT EXPECTING ANYTHING MORE THAN MINOR FLOODING AT
WORST.
