AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
1012 PM EDT SUN OCT 19 2014

.SYNOPSIS...
GUSTY NORTHWEST WINDS WILL BRING COLDER AIR TO SOUTHERN NEW
ENGLAND TONIGHT. HIGH PRESSURE MOVES OVER THE REGION ON MONDAY. A
DISTURBANCE DROPPING THROUGH THE GREAT LAKES WILL GENERATE A LONG
DURATION COASTAL STORM TUESDAY THROUGH FRIDAY WITH PERIODS OF
HEAVY RAIN. CONDITIONS LOOK TO IMPROVE SLOWLY BY NEXT WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...

10 PM UPDATE...

HIGH PRESSURE IN UPSTATE NY WILL CONTINUE TO MOVE EASTWARD TOWARDS
SOUTHERN NEW ENGLAND. PRESSURE GRADIENT IS STILL RELATIVELY TIGHT
FROM DEPARTING SYSTEM SO WIND GUSTS ARE STILL UP FOR PORTIONS OF
THE REGION...ESP HIGHER TERRAIN. STRONG CAA COMBINED WITH THE
RELATIVELY WARM WATERS WILL KEEP COASTAL LOCATIONS GUSTY AS WELL.
THIS WILL LIMIT THE RADIATIONAL COOLING ASPECT.

UPSTREAM...HIGH CIRRUS IS MOVING ACROSS UPSTATE NY IN CONJUCTION
WITH THE SURFACE RIDGE AXIS. THESE CLOUDS WILL MAKE THERE WAY INTO
WESTERN CT AND MA. BIGGEST QUESTION IS THERE THICKNESS AND HOW/IF
THEY WILL LIMIT RADIATIONAL COOLING. RIGHT NOW BELIEVE THE AIRMASS
WILL BE COLD ENOUGH THAT WE WILL STILL SEE FREEZING TEMPS AFTER
THE WINDS DECOUPLE IN A FEW HOURS.

OTHERWISE DRY WEATHER WILL PREVAIL OVERNIGHT AND NO CHANGES ARE
PLANNED FOR THE FROST/FREEZE HEADLINES.

&&

.SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/...
MONDAY...
HIGH PRESSURE CRESTS OVER THE REGION. WINDS WILL SHIFT AROUND TO
SOUTHWEST DURING THE AFTERNOON. EXPECT SOME INCREASE IN MID AND
HIGH CLOUDS BUT OVERALL A FAIR WEATHER DAY. MIXING SHOULD REACH TO
925 MB...POSSIBLY A LITTLE HIGHER. TEMPS EQUIVALENT TO -1C/-3C AT
850 MB...SUPPORTS MAX TEMPS IN THE 50S.

MONDAY NIGHT...
RIDGE MOVES OFF TO THE EAST WHILE A TROUGH DIGS OVER THE GREAT
LAKES. THIS TURNS OUR UPPER FLOW INTO A SOUTHWEST FLOW. WEAK HINTS
IN THE MODEL DATA OF A 70-KNOT JET OVERHEAD OF THE NORTHEAST
USA. THE RIGHT ENTRANCE REGION OF THIS POSSIBLE JET IS LOCATED
SOUTH OF THE REGION SUGGESTING THE BEGINNING OF CYCLOGENESIS ALONG
THE MID ATLANTIC COAST. MEANWHILE THE SOUTHWEST FLOW WILL BE
TRANSPORTING MOISTURE UP THE COAST IN CLOUDS. EXPECT INCREASING
AND THICKENING CLOUDS THROUGH THE NIGHT WITH POTENTIAL FOR
INCREASING LIFT. THE MOISTURE AND LIFT WOULD LEAD TO A CHANCE OF
RAIN LATE AT NIGHT. TEMPS WILL INITIALLY COOL IN THE EVENING WITH
ENOUGH TIME TO DROP 10-15 DEGREES FROM DAYTIME HIGHS. WE USED A
RANGE OF MIN TEMPS IN THE UPPER 30S AND 40S.

&&

.LONG TERM /TUESDAY THROUGH SUNDAY/...
HIGHLIGHTS...

* A LONG DURATION COASTAL STORM WILL IMPACT NEW ENGLAND FROM TUE
  THROUGH AT LEAST THU. PERIODS OF HEAVY RAIN APPEAR TO BE THE
  PRIMARY THREAT. A BRIEF PERIOD OF GUSTY WINDS ARE ALSO POSSIBLE
  TUE NIGHT AND WED ALONG THE IMMEDIATE NE MASS COAST.
* THE LOW LOOKS TO PUSH SLOWLY NE DURING THU...THOUGH INCLEMENT
  WEATHER MAY LINGER INTO FRI AS THE UPPER LOW SLOWLY MOVES AWAY.
* EXPECT GENERALLY DRY WEATHER NEXT WEEKEND...THOUGH MAY SEE A FEW
  SHOWERS LATE SAT NIGHT/SUN AS COLD FRONT PASSES.

OVERVIEW AND MODEL PREFERENCES...

OVERALL 12Z OP MODELS AS WELL AS ENSEMBLE GUIDANCE CONTINUE TO
SIGNAL DEVELOPMENT OF H5 CUTOFF LOW PRES ACROSS NORTHEAST AND MID
ATLC STATES DURING MOST OF THIS TIMEFRAME. BY THE BEGINNING OF
THIS TIMEFRAME...THE UPPER LOW ALREADY TAKING SHAPE OVER THE
APPALACHIANS...PUSHING OFF THE NJ/DELMARVA COASTLINE BY MID WEEK.
QUESTION WILL BE WHERE THE SURFACE FEATURE FORMS AND EVENTUALLY
SETS UP SHOP. ANOTHER ISSUE WILL BE DEVELOPING STRONG E-NE LOW
LEVEL JET AND HOW CLOSE THIS WILL COME TO THE E COAST...OR IF IT
REMAINS N OF THE REGION LATE TUESDAY INTO WEDNESDAY. THE UPPER
SYSTEM AND SURFACE LOW MEANDER THROUGH LATE THU...THEN LOOKS TO
SLOWLY EXIT TO NOVA SCOTIA...THOUGH STILL SOME TIMING ISSUES NOTED
ON OPERATIONAL MODELS. GENERAL SIGNAL ON DETERMINISTIC AND
ENSEMBLE MODELS SIGNALING IMPROVED CONDITIONS BY NEXT WEEKEND.

USED A BLEND OF AVAILABLE GUIDANCE INTO THURSDAY...THEN
TRANSITIONED OVER TO ENSEMBLE GUIDANCE WHERE HIGHER TIMING
UNCERTAINTY STILL IN PLAY.

DAILIES...

TUESDAY...
VIGOROUS H5 SHORT WAVE TROUGH CONTINUES TO DIG AS IT SHIFTS SE
OUT THE EASTERN LAKES EARLY TUE. QUICKLY DEEPENING TROUGH TAKES
SHAPE LATE TUE/TUE NIGHT...WHILE SURFACE LOW STARTS TO FORM TUE
NIGHT SOMEWHERE OFF THE DELMARVA/NJ COAST. AREA OF RAIN CONTINUES
TO DEVELOP AND EXPAND FROM E-W ACROSS THE REGION. NOTING BAND OF
HEAVIER RAINFALL OFFSHORE...BUT QUESTION WILL BE WHETHER SOME OF
THIS WILL WORK INLAND. AT THIS POINT...SHOULD REMAIN OFFSHORE BUT
SOMETHING TO MONITOR. MAY SEE SOME HEAVIER PRECIP MAKE IT INTO NE
MA/S CENTRAL NH OVERNIGHT TUE NIGHT.

QUESTION REMAINS ABOUT STRONGER E-NE WINDS THAT MAY TRY TO WORK
ONSHORE WITH THE STRONG LOW LEVEL JET WORKING AROUND THE DEVELOP
CUTOFF UPPER LOW. AT THIS POINT...STILL LOOKS LIKE THEY WILL HAVE A
TOUGH TIME MIXING DOWN AS LAPSE RATES REMAIN LOW /AROUND 2-3C/KM/
BUT COULD SEE SOME GUSTY WINDS WORK DOWN WITH ANY HEAVIER RAINFALL
TUE NIGHT MAINLY ACROSS NE COASTAL MA.

HIGHS ON TUE WILL MAKE IT TO BETWEEN 60 AND 65 ALONG THE
COAST...BUT ONLY THE MID-UPPER 50S ACROSS THE HIGHER TERRAIN.

TUESDAY NIGHT THROUGH THURSDAY NIGHT...
EXACT TIMING AND STORM IMPACTS REMAIN UNCERTAIN...THOUGH DOES LOOK
LIKE THE MAIN THREAT WILL BE PERIODS OF HEAVY RAINFALL. USING A
BLEND OF AVAILABLE MODEL GUIDANCE...QPF TOTALS FOR THIS TIMEFRAME
LOOK TO BE A BIT LESS THAN PREVIOUS FORECAST...GENERALLY AROUND
1.25 INCHES ON THE S COAST RANGING UP TO 1.75 TO AROUND 2 INCHES
ACROSS NE MA INTO S NH. QPF COULD INCREASE IF HEAVIER RAIN BANDS
MOVE ACROSS...THOUGH. EXPECT STEADY RAIN FROM TUE NIGHT INTO THU
NIGHT...THEN SHOULD BEGIN TO TRANSITION TO SHOWERS ACROSS THE CT
VALLEY AFTER MIDNIGHT THU NIGHT AS THE SURFACE LOW LOOKS TO SLOWLY
HEAD NE WHILE THE UPPER LEVEL SYSTEM LINGERS ACROSS THE REGION.

MODELS CONTINUE TO SIGNAL THE STRONG WIND THREAT TO REMAIN N OF THE
REGION...BUT CAN NOT TOTALLY RULE OUT SOME GUSTS UP TO 25 KT OR SO
ACROSS NE MA INTO S CENTRAL NH DEPENDING UPON POSITION OF JET AXIS
DURING TUE NIGHT INTO WED. SOMETHING TO MONITOR.

WITH STRONGEST E-NE WINDS PUSHING N OF THE REGION...THREAT FOR
COASTAL FLOODING REMAINS LOW. SEAS DO BUILD OFF THE E MA COAST AND
COULD SEND SOME HIGHER SWELLS TOWARD THE SHORE BY WED/THU...AND WILL
CONTINUE TO MONITOR THE LOW LEVEL HIGH WIND AXIS TO SEE IF IT SHIFTS
FURTHER S.  WITH INCREASING SWELLS...RISK CONTINUES FOR COASTAL
BEACH EROSION WITH THE WAVE ACTION OVER SEVERAL HIGH TIDE CYCLES.

FRIDAY...
QUESTION AT THIS POINT IS HOW QUICKLY WILL THE SURFACE LOW DEPART
DURING FRIDAY. MODELS HAVE DIFFERENT TIMING ON THIS...BUT
GENERALLY LOOKS TO PUSH TOWARD NOVA SCOTIA BY LATE FRIDAY.
HOWEVER...COULD STILL SEE SOME LINGERING SHOWERS ON BACK SIDE INTO
FRI NIGHT ACROSS E MA/S CENTRAL NH AS UPPER LEVEL SYSTEM SLOWLY
PUSHES E. AT THIS POINT...SHOULD SEE IMPROVING CONDITIONS
OVERNIGHT FRI.

NEXT WEEKEND...
LOOKS TO BE A DRY SEASONABLE WEEKEND AS NW WINDS AT THE SURFACE
AND ALOFT TAKE OVER. SOME QUESTION AS TO APPROACH OF FAST MOVING
H5 SHORT WAVE AS ASSOCIATED SURFACE COLD FRONT QUICKLY CROSSING
THE REGION SAT NIGHT/EARLY SUN. NOT MUCH MOISTURE AT SURFACE...FOR
NOW...BUT COULD SEE A FEW SHOWERS ACROSS S NH/N MA AS THE FRONT
PASSES.

THE EASTERN OPEN WATERS TO 5-8 FT BY EARLY WED...WITH THE HIGHEST
SEAS ON THE FAR OUTER WATERS...THEN UP TO 5 FT ON THE SOUTHERN

SEAS WILL REMAIN AOA 5 FT. PERIODS OF HEAVY RAIN AND PATCHY FOG
WILL REDUCE VSBY.
