AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
702 AM EDT WED SEP 30 2015
.SYNOPSIS...
A COLD FRONT WILL MOVE INTO SOUTHERN NEW ENGLAND LATER THIS MORNING
THROUGH THE AFTERNOON...STALLING OFFSHORE TONIGHT. WAVES OF LOW
PRESSURE WILL MOVE ALONG THIS FRONT THROUGH LATE WEEK WITH POTENTIAL
FOR MORE HEAVY RAINFALL LATE THURSDAY THROUGH FRIDAY. IN
ADDITION...POTENTIAL REMAINS FOR STRONG COASTAL NORTHEAST WINDS AND
MINOR COASTAL FLOODING. THESE THREATS MAY PERSIST INTO THIS WEEKEND
DEPENDING ON THE EVENTUAL TRACK OF WHAT IS LIKELY TO BECOME
HURRICANE JOAQUIN...WHICH WILL NEED TO BE MONITORED CLOSELY.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
** FLOOD WATCH REMAINS IN EFFECT **
** COASTAL FLOOD STATEMENT WILL CONTINUE FOR THE SOUTH COAST TODAY**
7 AM UPDATE...
HEAVY RAINFALL IS LIFTING NORTH ACROSS THE REGION ASSOCD WITH THE
SOUTHERLY LLJ FOCUSING LOW LEVEL CONVERGENCE WITHIN DEEP THETA-E
PLUME AND ANOMALOUS +3SD PWAT AXIS. RAINFALL RATES UP TO AN INCH
PER HOUR IN THE HEAVIER RAIN BANDS AND CANT RULE OUT AN ISOLD
TSTM. RAIN AREA IS MOVING QUITE RAPIDLY AND EXPECT THE RAIN TO
TAPER OFF MID MORNING TO EARLY AFTERNOON FROM WEST TO EAST AS THE
LOW LEVEL JET MOVES EAST OF NEW ENG AFT 18Z.
COLD FRONT HAS MOVED INTO THE BERKSHIRES AND WILL BE SLOWLY MOVING
EAST ACROSS SNE REACHING BOS-PVD CORRIDOR LATE TODAY. MODELS
INDICATE STRONG LOW LEVEL FRONTOGENESIS AND DEEP MOISTURE REMAINS
SO CANT RULE OUT ADDITIONAL BRIEF HEAVY SHOWERS THIS AFTERNOON
ALONG THE COLD FRONT.
RATHER WARM AND HUMID TODAY AHEAD OF THE FRONT WITH TEMPS GETTING
WELL INTO THE 70S AND DEWPOINTS AROUND 70. TURNING SHARPLY COOLER
BEHIND THE FRONT WITH TEMPS FALLING INTO 50S THIS AFTERNOON ACROSS
WESTERN MA.
SOUTHEASTERLY LLJ CONTINUES TO STRENGTHEN PRE RADAR VWP THIS
MORNING. SOME WIND MAY MIX DOWN BUT OVERALL LAPSE RATES ARE NOT
STEEP ENOUGH EARLY THIS MORNING. HOWEVER WITHIN AND STRONG STORM
THAT MAY DEVELOP...WE COULD SEE A GUST OF 25-30 MPH. THIS LLJ WILL
ALSO INCREASE WAVE ACTION AND SWELL INCREASING THE POTENTIAL FOR
SPLASHOVER DURING THE MORNING HIGH TIDE ACROSS THE SOUTH COAST.
PLEASE SEE COASTAL FLOOD SECTION FOR MORE DETAIL.
THIS AFTERNOON...
SURFACE LOW WILL CONTINUE ITS NORTHEAST TRAJECTORY AND PUSH THE
BETTER FORCING AND LIFT NORTH OF THE AREA. SURFACE COLD FRONT WILL
CONTINUE TO MOVE EASTWARD ALLOWING FOR WINDS TO SWITCH TO A
NORTHERLY DIRECTION BEHIND THE FRONT. THIS WILL BRING IN COOLER
AND DRY AIR. IN FACT TEMPS WILL BE FALLING ACROSS THE DAY ESP IN
WESTERN AND NORTHERN MASS.
STILL THE POTENTIAL FOR A FEW ISO THUNDERSTORMS OUT AHEAD OF THE
FRONT AS IT MOVES OVER THE REGION THIS AFTERNOON. HIGH TEMPS ESP
ACROSS THE 95 CORRIDOR COULD WARM INTO THE MID TO UPPER 70S AS THE
FRONT TAKES IT TIME MOVING EASTWARD. THESE WARM TEMPS COMBINED WITH
HIGH DEWPOINTS COULD CREATE ENOUGH INSTABILITY TO TRIGGER A
THUNDERSTORM OR TWO. OTHERWISE APPEARS THAT THE BULK OF THE PRECIP
WILL BE WINDING DOWN AFTER 15Z AND MORE LIKELY BY 18Z. JUST SHOWERY
WEATHER WILL IMPACT SNE FOR THE AFTERNOON HOURS. SOME OF THESE
SHOWERS MAY STILL CONTAIN HEAVY RAINFALL AS PWAT STILL REMAIN ABOVE
2 INCHES FOR MUCH OF THE DAY.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM THURSDAY/...
TONIGHT...
PRECIP WILL BE WINDING DOWN TONIGHT WITH A SHOWER OR TWO LINGERING
ACROSS THE CAPE AND ISLANDS. SURFACE COLD FRONT LOOKS TO MAKE IT TO
THE CANAL BY 00Z AND THEN STALL OFFSHORE OVERNIGHT.
AS MENTIONED ABOVE...NORTHERLY WINDS BEHIND THE FRONT WILL ALLOW FOR
DRY AIR TO FILTER IN OVERNIGHT. THIS WILL BRING TEMPS DOWN INTO THE
UPPER 40S TO LOW 50S. FOG MAY BE AN ISSUE TONIGHT WITH THE POTENTIAL
FOR LOW LEVEL INVERSION SETTING UP TRAPPING THE LOW LEVEL MOISTURE
FROM THE RECENT RAINFALL. WILL LET DAY SHIFT DECIDED IF HEADLINES
ARE NEEDED.
&&
.LONG TERM /THURSDAY THROUGH TUESDAY/...
HIGHLIGHTS...
* MORE HEAVY RAINFALL THU NIGHT THROUGH FRIDAY NEAR THE SOUTH COAST
WITH STRONG COASTAL NE WINDS
* MINOR COASTAL FLOODING POSSIBLE DURING THE HIGH TIDES THU INTO FRI
* WEATHER IMPACTS THIS WEEKEND WILL DEPEND OF THE TRACK OF WHAT IS
LIKELY TO BECOME HURRICANE JOAQUIN
OVERVIEW...
FAIRLY HIGH CONFIDENCE FORECAST FOR LATE IN THE WEEK AS NORTH
ATLANTIC BLOCKING RIDGE KEEPS FRONT STALLED JUST SOUTH OF THE
REGION. WHILE AXIS OF HIGHEST PWATS REMAIN OFFSHORE WITH THE
FRONT...ANOMALOUS PWAT PLUME OF +2SD WILL EXTEND ACROSS SE NEW ENG
WITH INCREASING LOW LEVEL NE FLOW WHICH REACHES +3 TO +4SD. RESULT
WILL BE ANOTHER SURGE OF HEAVY RAINFALL ALONG THE SOUTH COAST.
LOOKING AHEAD TO THE WEEKEND...THE FORECAST ALL COMES DOWN TO THE
EVENTUAL TRACK OF JOAQUIN WHICH IS FORECAST TO BECOME A HURRICANE.
THERE IS STILL A FAIR AMOUNT OF SPREAD IN THE TRACK FORECAST AMONG
GLOBAL AND TROPICAL MODELS WITH ECMWF SOLUTION OF OUT TO SEA A
LIKELY OUTLIER GIVEN STRONG DOWNSTREAM BLOCKING. CONSENSUS FAVORS A
TURN TO THE NW WITH LANDFALL SOMEWHERE ALONG THE MID ATLC COAST FROM
NC TO SOUTHERN NJ LATE IN THE WEEKEND. HOW FAR N JOAQUIN GETS WILL
PLAY A SIGNIFICANT ROLE ON SENSIBLE WEATHER IN SNE. AT THE VERY
LEAST IT DOES APPEAR ANOTHER PULSE OF HEAVY RAIN AND GUSTY COASTAL
WINDS MAY AFFECT THE REGION OVER THE WEEKEND BUT THERE IS LOW
PREDICTABILITY AS TO THE DETAILS AND THE EXTENT OF RAIN AND WIND.
DAILIES...
THURSDAY INTO FRIDAY...
FRONT STALLS SOUTH OF THE REGION WITH ANOMALOUS HIGH PRES TO THE
NORTH RESULTING IN INCREASING NE FLOW. DEEPER MOISTURE WILL BE S OF
NEW ENG TO START THU...BUT WITH SOUTHERLY ALOFT THIS MOISTURE WILL
LIFT BACK N INTO SNE WITH RAIN DEVELOPING ALONG THE S COAST DURING
THU AFTERNOON. HOWEVER...THERE WILL BE A SHARP CUTOFF ON THE
NORTHERN FRINGE WITH MUCH OF THE RAIN CONFINED TO THE S COAST WITH
DRY WEATHER ALONG AND N OF THE MASS PIKE. RAIN WILL EVENTUALLY
EXPAND NORTH ACROSS REST OF SNE THU NIGHT INTO FRI AS DEEPER
MOISTURE LIFTS N IN THE FAVORABLE RIGHT ENTRANCE REGION OF UPPER
JET...WITH PERIODS OF HEAVY RAIN ALONG THE SOUTH COAST ASSOCD WITH
INCREASING LOW LEVEL CONVERGENCE AND FRONTOGENESIS. LOW LEVEL WIND
ANOMALIES INCREASE TO 3-4SD ABOVE NORMAL SO WE HAVE HIGH CONFIDENCE
OF HEAVY RAIN ALONG THE S COAST. RAINFALL AMOUNTS THU THROUGH FRI
WILL LIKELY RANGE FROM 1-2 INCHES ACROSS RI AND SE MA WITH LOCALLY 3
INCHES POSSIBLE...ESPECIALLY THE ISLANDS. GEFS ENSEMBLES INDICATE
HIGH PROBS OF GREATER THAN 2 INCHES NEAR THE SOUTH COAST. RAINFALL
AMOUNTS WILL DROP OFF CONSIDERABLY NORTH OF THE MASS PIKE. TEMPS THU
WILL BE UPPER 50S TO LOWER 60S...COOLING INTO THE LOW TO MID 50S
FRI...AND WITH THE RAIN AND GUSTY NE WINDS IT WILL FEEL QUITE RAW.
GUSTY NE WINDS WILL DEVELOP THU AND ESPECIALLY THU NIGHT INTO FRI IN
RESPONSE TO INCREASING LOW LEVEL WINDS. GOOD MIXING SUPPORTS GUSTS
TO 30-40 MPH NEAR THE COAST WITH HIGHER GUSTS OVER THE ISLANDS
WHERE WIND ADVISORIES MAY BE NEEDED.
SATURDAY INTO TUESDAY...
FORECAST DEPENDS ON TRACK OF JOAQUIN AND WHERE IT MAKES LANDFALL. WE
DO EXPECT ANOTHER PULSE OF HEAVY RAIN AND GUSTY WINDS...BUT DETAILS
ON TIMING AND MAGNITUDE OF RAIN AND WIND IS VERY MUCH UNCERTAIN.
LATEST GEFS ENSEMBLE GUIDANCE SUGGESTS SUNDAY INTO MONDAY WILL BE
THE WETTEST PERIOD WITH A LULL ON SATURDAY. MAGNITUDE OF COASTAL
WIND WILL DEPEND ON HOW FAR N JOAQUIN TRACKS.

IS UNCERTAIN AT THIS TIME RANGE. EXPECT PERIODS OF HEAVY RAIN AND
REDUCED VSBYS...ESPECIALLY LATE THU THROUGH FRI. MORE RAIN POSSIBLE
THIS WEEKEND.

.TIDES/COASTAL FLOODING...
WEDNESDAY ALONG SOUTH COAST...
COMBINATION OF HIGH ASTRONOMICAL TIDE AND SOUTHERLY FETCH WARRANTS
COASTAL FLOOD ADVISORY FOR PORTIONS OF THE RI AND MA SOUTH
COAST. ANTICIPATING A SURGE NEAR 1.0 FEET...JUST A FEW FEET ABOVE
THE ESTOFS GUIDANCE FOR THE WEDNESDAY MID TO LATE MORNING HIGH
TIDE IN THAT AREA. THAT IS THE ONLY HIGH TIDE CYCLE OF CONCERN FOR
THE SOUTH COAST.
WEDNESDAY NIGHT THROUGH FRIDAY ALONG EAST COAST...
BEHIND THE COLD FRONT THE WIND INCREASES FROM THE NE AND WE BEGIN
TO SEE POSITIVE SURGES ALONG THE MA EAST COAST...STARTING WED
NIGHT. A SURGE OF .5 TO 1.0 FEET MAY BE ENOUGH FOR AREAS OF MINOR
COASTAL FLOODING ALONG THE E COAST LATE WED NIGHT/VERY EARLY THU
AM. AS THE NE FLOW PERSISTS...WE SEE THE POTENTIAL FOR THE SURGE
TO INCREASE INTO THE 1.0 TO 1.5 FOOT RANGE WITH ADDITIONAL MINOR
COASTAL FLOODING POSSIBLE AROUND THE TIME OF HIGH TIDE...WITH
HIGHEST PROBABILITY DURING THE THU AND FRI AFTERNOON TIDE CYCLES.
COASTAL FLOOD ADVISORIES WILL LIKELY BE NEEDED FOR THE E COAST. SOME
IN ADDITION...BEACH EROSION IS LIKELY DUE TO THE HIGH WATER LEVELS
AND MODERATE WAVE ACTION THAT MAY APPROACH JUST 15 FEET OFFSHORE.
WEEKEND OUTLOOK... THE WEEKEND OUTLOOK IS HIGHLY UNCERTAIN AS IT
DEPENDS IN PART ON THE EVOLUTION OF JOAQUIN. PRELIMINARY INDICATIONS
SUGGEST A PERSISTENT NE FLOW THAT COULD KEEP THE SURGE RUNNING 1 TO
1.5 FEET WHILE THE ASTRONOMICAL HIGH TIDES GRADUALLY BECOME LESS.
