Flooding in Massachusetts, September 10, 2015

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
1049 AM EDT THU SEP 10 2015

.SYNOPSIS...
A WEAK COLD FRONT WILL STALL ALONG THE SOUTHERN NEW ENGLAND
COASTLINE THIS AFTERNOON. A WAVE OF LOW PRESSURE WILL TRAVEL ALONG
THE FRONT LATE AFTERNOON AND TONIGHT...BRINGING WIDESPREAD
SHOWERS AND SOME THUNDERSTORMS ALONG WITH LOCALLY HEAVY RAINFALL.
THE LOW DEPARTS ON FRIDAY. WEAK HIGH PRESSURE THEN BRINGS DRY AND
MILD CONDITIONS FOR SATURDAY. AN ANOMALOUS WEATHER SYSTEM MOVES
EAST...WITH MORE RAIN MOVING IN LATE THIS WEEKEND BEFORE EXITING
MONDAY. HIGH PRESSURE LOOKS TO RETURN WITH DRY CONDITIONS AND
ABOVE NORMAL TEMPERATURES INTO THE MIDDLE OF NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

MOIST AIR REMAINS IN PLACE OVER SOUTHERN NEW ENGLAND WITH DEEP
MOISTURE IN PLACE. PRECIPITABLE WATER VALUES OF 1.8 TO 2.1 INCHES
EXTEND FROM CAPE COD TO LONG ISLAND SOUND. VALUES DIMINISH TO 1.5
NEAR THE NH BORDER.

FAVORABLE STABILITY PARAMETERS AND DEEP MOISTURE ARE IN PLACE. LOW
PRESSURE OVER THE MID ATLANTIC STATES IS DIRECTING SOUTHERLY LOW
LEVEL WINDS UP THE COAST AND OVER THE STALLED FRONT. THIS MEANS LOW
LEVEL CONVERGENCE ALONG THE STALLED FRONT AT THE SURFACE...AND ITS
REFLECTIONS UP TO 5000 FEET. ALL OF THIS WILL WORK FAVORABLY TO
GENERATE ADDITIONAL SHOWERS/SCATTERED TSTMS DURING THE AFTERNOON.
THE DEEP MOISTURE IS AROUND 2 STD DEV ABOVE NORMAL. ALL OF THIS
MEANS POTENTIAL FOR LOCALLY HEAVY DOWNPOURS WITH URBAN/POOR
DRAINAGE FLOODING A CONCERN THAT WE WILL MONITOR.

WITH THE COASTAL AREAS WORKED OVER DURING THE MORNING...THE FOCUS
FOR CONVECTION MAY SHIFT FARTHER NORTH/WEST FOR THE
AFTERNOON/EVENING. MOVEMENT OF EXISTING CONVECTION UPSTREAM NEAR
NYC WOULD ALSO SUGGEST THIS.

NO CHANGES TO THE TEMPERATURE FORECASTS.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...
LOW PRESSURE DEVELOPS ALONG THIS STALLED FRONT OFF THE MID
ATLANTIC COAST TONIGHT...THEN PASSES BY SOUTHERN NEW ENGLAND
FRIDAY MORNING. THIS IS MORE OF A CLASSIC COLD SEASON SCENARIO
THAN OF SUMMER. THUS EXPECTING PROLONGED PERIOD OF WIDESPREAD
SHOWERS TONIGHT. SHOWERS DIMINISH...WITH CLEARING FROM WEST TO
EAST FRIDAY AS THE LOW PRESSURE MOVES BY.

INSTABILITY REMAINS LIMITED ACROSS SOUTHERN NEW ENGLAND...BUT NOT
COMPLETELY MISSING. WILL CONTINUE TO MENTION AT LEAST A FEW
THUNDERSTORMS TONIGHT INTO FRIDAY. THE MAIN THREAT REMAINS LOCALLY
HEAVY RAINFALL LEADING TO POOR-DRAINAGE FLOODING. STORM TOTAL
RAINFALL OF 1-2 INCHES...WITH LOCALLY HIGHER AMOUNTS REMAIN
POSSIBLE BY FRIDAY AFTERNOON.

SEASONABLE TEMPERATURES EXPECTED TONIGHT AND FRIDAY.

&&

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

* WEAK HIGH PRESSURE BRINGS DRY AND MILD CONDITIONS SATURDAY
* WET WEATHER RETURNS ALONG WITH A FEW THUNDERSTORMS POSSIBLE SUNDAY
  INTO EARLY MONDAY
* LOOKING FOR DRY AND WARM CONDITIONS INTO THE MIDDLE OF NEXT WEEK

OVERVIEW...
AFTER LOW PRES AND COLD FRONT MOVE OFFSHORE...RATHER ANOMALOUS
PATTERN SETS UP FOR THIS WEEKEND. MODELS REMAIN IN GOOD AGREEMENT
WITH DIGGING H5 TROUGH WITH LOW TRYING TO CLOSE OFF ON SOME RUNS.
PROGRESSIVE PATTERN IS IN PLACE THOUGH...SO THIS LOW WILL MOVE NE
OVER THE WEEKEND. ANOTHER PERIOD OF RAINFALL FOR SUNDAY INTO
MONDAY AS THIS SYSTEM PROGRESSES. ONCE THIS SYSTEM MOVES
OFF...MODELS AND ENSEMBLES CONTINUE TO SIGNAL HIGH AMPLITUDE
RIDGING REDEVELOPING ACROSS THE NORTHEAST INTO EASTERN CANADA WITH
SURFACE HIGH RE- ESTABLISHING AS TROUGH DIGS ALONG THE WEST COAST.
WILL ALSO SEE A RETURN TO WARM TEMPS INTO THE MIDDLE OF NEXT
WEEK...WITH HIGHS RUNNING 5 TO 10 DEGREES ABOVE SEASONAL NORMALS
FOR MID SEPTEMBER.

DETAILS...

FRIDAY NIGHT-SATURDAY...
AS LOW PRES PUSHES OFFSHORE FRI NIGHT...WILL SEE DRY CONDITIONS
MOVE IN THOUGH CLOUDS MAY LINGER EARLY ACROSS EASTERN AREAS. MAY
ALSO SEE SOME PATCHY FOG DEVELOP ESPECIALLY IN AREAS WHERE HEAVIER
RAIN FELL DURING FRIDAY. BUBBLE HIGH PRES MOVES ACROSS LATE FRI
NIGHT AND SAT...SO WILL REMAIN DRY. LIGHT N-NW WINDS WILL BE IN
PLACE...THOUGH SEA BREEZES WILL LIKELY DEVELOP ALONG THE E COAST.
EXPECT SATURDAYS HIGHS IN THE MID 70S TO AROUND 80.

UNUSUALLY STRONG UPPER LEVEL LOW/TROUGH MOVING OUT OF THE OHIO
VALLEY MAY START TO BRING SOME CLOUDS AND POSSIBLY SOME SCT
SHOWERS INTO WESTERN AREAS SAT AFTERNOON...MAYBE EVEN AN ISOLD
THUNDERSTORM MAINLY ACROSS THE E SLOPES OF THE BERKSHIRES THOUGH
THE AIRMASS IS ONLY MARGINALLY UNSTABLE.

SATURDAY NIGHT-SUNDAY NIGHT...
CUTOFF H5 LOW MOVES E-NE THROUGH NY/PA DURING THIS TIMEFRAME...
WITH COMPLEX SURFACE LOW AND FRONT MOVING INTO THE REGION. NOTING
SOME DECENT PWATS MOVING INTO CENTRAL AND SOUTHERN AREAS...UP TO
1.5 TO 1.7 INCHES DURING SUNDAY. MAY SEE SOME LOCALLY HEAVIER
RAINFALL ACROSS THE CT VALLEY INTO THE E SLOPES OF THE BERKSHIRES
AS WINDS SHIFT TO E-SE BRINGING UPSLOPE LOW LEVEL MOISTURE IN.

MOST OF THE ORGANIZED ENERGY AND INSTABILITY REMAINS CLOSER TO
THE LOW W OF THE REGION...BUT COULD STILL SEE SOME ISOLD
THUNDERSTORMS ANYTIME AS THE TRIPLE POINT SYSTEM STARTS TO MOVE
ACROSS. LOOKS LIKE BEST SHOT FOR MAINLY ELEVATED CONVECTION WILL
BE DURING SUNDAY INTO EARLY SUNDAY NIGHT.

MONDAY...
CUTOFF LOW OPENS TO A TROUGH AS IT CROSSES THE REGION. SURFACE
SYSTEM WILL SHIFT OFFSHORE MON MORNING. WILL SEE SOME LINGERING
SHOWERS ACROSS THE REGION WHICH LOOK TO LIFT N-NE DURING THE DAY.

DURING THE AFTERNOON...WHILE SOME SPOTTY SHOWERS COULD LINGER
THROUGH MOST OF THE DAY MAINLY ACROSS N MA. WITH THE UPPER LEVEL
COLD POOL CROSSING THE REGION...EXPECT HIGHS IN THE LOWER-MID
70S...WHICH IS ACTUALLY CLOSE TO SEASONAL NORMALS.

TUESDAY-WEDNESDAY...
LARGE HIGH PRES WILL BUILD IN ACROSS AND S OF THE REGION DURING
THIS TIMEFRAME AS UPPER LEVEL RIDGING RETURNS. WILL SEE TEMPS
SOAR BACK TO ABOVE NORMAL LEVELS WITH HIGHS RUNNING IN THE MID 70S
TO AROUND 80. MODELS AND ENSEMBLES CONTINUE TO SIGNAL SW WINDS
TAKING OVER... WHICH ALSO MEANS A RETURN TO MORE HUMID CONDITIONS
ESPECIALLY ON WEDNESDAY.
