AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
701 PM EDT WED SEP 11 2013

.SYNOPSIS...
A VERY WARM AND HUMID AIRMASS WILL REMAIN OVER THE REGION THROUGH
THURSDAY. A FEW THUNDERSTORMS WITH STRONG WINDS AND HAIL MAY AFFECT
THE FAR INTERIOR THIS EVENING WITH MORE WIDESPREAD SHOWERS AND
THUNDERSTORMS CONTAINING HEAVY RAIN LATE THURSDAY INTO THURSDAY
NIGHT...AS A COLD FRONT ENTERS THE REGION. THE FRONT MOVES
OFFSHORE FRIDAY FOLLOWED BY HIGH PRESSURE THIS WEEKEND WITH DRY
AND MUCH COOLER WEATHER. A WEAK BUT DRY COLD FRONT WILL MOVE
THROUGH ON MONDAY FOLLOWED BY YET ANOTHER AREA OF HIGH PRESSURE
THEREAFTER.

&&

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

*** A FEW STRONG STORMS REMAIN POSSIBLE FAR INTERIOR ***

7 PM UPDATE...

POTENTIAL CONVECTION...

TSTMS REMAIN JUST WEST OF NEW ENGLAND ACROSS EASTERN NY.
ATMOSPHERE IS PRIMED FOR CONVECTION OVER WESTERN MA WITH DEEP
LAYER MOISTURE AS K INDICES HAVE INCREASED TO 40...MLCAPES UP TO
4500J/KG AND MID LEVEL LAPSE RATES OF 7C/KM. DEEP LAYER SHEAR IS
LACKING AT LESS THAN 30 KT HOWEVER STILL THINK INCREASING HEIGHT
FALLS FROM APPROACHING SHORT WAVE WILL PROVIDE THE NECESSARY
FORCING FOR ASCENT FOR CONVECTION TO ADVANCE NORTHEAST INTO
WESTERN MA AND SOUTHWEST NH. IN ADDITION COLD POOL EMANATING FROM
THE CONVECTION MAY BE SUFFICIENT FOR CONVECTION TO SUSTAIN ITSELF
INTO WESTERN NEW ENGLAND. SEVERAL CONSECUTIVE RUNS OF THE HRRR
CONTINUE TO SIMULATE CONVECTION INTO WESTERN MA AND SOUTHWEST NH
FROM 00Z TO ABOUT 04Z THEN WEAKENING.

IF CONVECTION DOES FIRE STRONG WINDS/LARGE HAIL AND HEAVY RAIN
REMAIN THE MAIN THREATS...ESPECIALLY WIND DAMAGE GIVEN THE HIGH
CAPE ENVIRONMENT. FARTHER EAST DRY WEATHER WILL PREVAIL.

TEMPERATURES...

VERY WARM AND MUGGY NIGHT AHEAD AS DEW PTS IN THE LOW TO MID 70S
WILL PRECLUDE MUCH BLYR COOLING. THIS LOW LEVEL MOISTURE WILL
RESULT IN PATCHY FOG LATE TONIGHT INTO EARLY THU MORNING.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...

*** LOW RISK OF FLOODING AND A FEW STRONG STORMS ***

THURSDAY...

MID LEVEL TROUGH OVER THE GREAT LAKES BEGINS TO SHARPEN/AMPLIFY.
THIS SLOWS THE EASTWARD PROGRESSION OF THE COLD FRONT A BIT...SO
IT LOOKS LIKE PRECIP WILL BE SLOWER TO ENTER THE REGION FROM WEST
TO EAST. IN FACT THERE MAY BE SUFFICIENT MID LEVEL DRY AIR TO
PRECLUDE MUCH IF ANY SHOWER/TSTM ACTIVITY TOMORROW ESPECIALLY
ACROSS RI AND EASTERN MA. THIS WILL ALSO YIELD AT LEAST PARTIAL SUNSHINE
AND WARM TEMPS...ALTHOUGH NOT AS HOT AS TODAY. HIGHS TOMORROW WILL
CLIMB INTO THE 80S BUT DEW PTS IN THE 70S WILL YIELD VERY
UNCOMFORTABLE CONDITIONS.

AS THE DEEP MOISTURE ARRIVES LATER IN THE DAY ALONG WITH STRONGER
JET DYNAMICS EXPECTING SHOWERS AND TSTMS TO BECOME MORE WIDESPREAD
ACROSS WESTERN NEW ENGLAND AFTER 4PM/5PM AND MAY HOLD OFF UNTIL
AFTER DARK ACROSS EASTERN MA AND RI. ANY STORMS THAT FORM ACROSS
WESTERN CT/MA AND SOUTHWEST NH LATE THU MAY BE STRONG GIVEN CAPES
OF 1500-2500 ALONG WITH MARGINAL DEEP LAYER SHEAR OF 20-30 KT.
HEAVY RAIN ALSO A CONCERN WITH THE HIGH THETA-E AIRMASS.

THURSDAY NIGHT...

STRONG JET DYNAMICS ARRIVE WITH SIGNS OF A DUAL JET COUPLET WITH
SOUTHERN NEW ENGLAND UNDER THE RRQ OF NORTHERN STREAM JET AND LFQ
OF OFFSHORE SOUTHERN STREAM JET /POSSIBLY ASSOCIATED WITH TS
GABRIELLE/. THIS STRONG LIFT COUPLED WITH WEAK INSTABILITY AND
INCREASING WIND FIELDS WILL YIELD A LOW RISK OF A FEW STORMS
CONTAINING STRONG/GUSTY WINDS. IN ADDITION...THIS INSTABILITY AND
STRONG FORCING WITH PWATS +1 TO +2 STD ABOVE CLIMO WILL YIELD A
RISK FOR FLASH FLOODING. LATER SHIFTS WILL HAVE TO EVALUATE THE
POTENTIAL FOR A FLASH FLOOD WATCH FROM LATE THU AND THU NIGHT.
MOST OF THE ACTIVITY SHOULD BE FOCUSED 00Z-06Z WESTERN NEW ENGLAND
AND THEN 06Z-12Z EASTERN MA AND RI.

ANOTHER WARM AND MUGGY NIGHT AS COLD FRONT DOESN/T MOVE OFFSHORE
UNTIL EARLY FRI.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
HEADLINES...

* WET WEATHER LINGERS FRIDAY MORNING...POTENTIAL FLOOD THREAT
* HIGH PRESSURE USHERS COOL AND DRY AIR FOR THE WEEKEND
* DRY COLD FRONTAL PASSAGE MONDAY...SLIGHT CHANCE OF SHOWERS
* RENEWED HIGH PRESSURE WITH EVEN COOLER AND DRIER AIR FOR THE WEEK

*/OVERVIEW AND MODEL CONSENSUS...

WHILE THE 11.0Z OPERATIONAL ECMWF DIVERGES FROM ITS ENSEMBLE
COUNTERPART BY MIDWEEK...IT IS NOTABLY SUCCINCT WITH THE 11.12Z
OPERATIONAL GFS. WILL CONSIDER A BLEND OF THE TWO AS THERE IS BROAD
AGREEMENT ON THE TRENDS OF COOLER AND DRIER CONDITIONS PREVAILING
UNDER THE INFLUENCE OF HIGH PRESSURE.

*/DAY-TO-DAY DETAILS...

*/FRIDAY...

CONSIDERING THE REMNANTS OF GABRIELLE INTERACTING WITH THE MID- TO
UPPER-LEVEL TROUGH...POPS ARE LIKELY AS LARGE-SCALE FORCING PREVAILS
ACROSS EASTERN AND SOUTHEASTERN PORTIONS OF NEW ENGLAND. CONSIDERING
THE COLLOCATION OF DECENT WARM-MOIST AIR AHEAD OF THE SURFACE COLD
FRONT LENDING TO SOME WEAK ELEVATED INSTABILITY...THUNDER WILL BE
INCLUDED IN THE FORECAST. THERE REMAINS A VIABLE FLOODING THREAT
ESPECIALLY FOR URBAN CORRIDORS AND DURING THE MORNING COMMUTE FOR
THOSE AREAS PREVIOUSLY MENTIONED...WILL INCLUDE WORDING OF HEAVY
RAIN AS PWATS UP TO 2 INCHES ARE ANTICIPATED. SHOULD SEE MOST OF THE
ACTIVITY SHIFT OFFSHORE BY AS LATE AS MIDDAY...WITH WINDS BACKING
WEST-NORTHWESTERLY USHERING COOLER AND DRIER AIR ACROSS THE REGION.

*/FRIDAY NIGHT INTO SUNDAY NIGHT...

COOL AND DRY FORECAST. HIGH PRESSURE BUILDS SOUTHEAST OUT OF CANADA
TOWARDS THE MID-ATLANTIC. WEST-NORTHWESTERLY WINDS INITIALLY WEAKEN
SUNDAY MORNING AS THE HIGH PUSHES OUT TO SEA ALLOWING RETURN
SOUTHERLY WINDS. SATURDAY WILL SEE A MIX OF CLOUDS WITH SOME BREEZY
CONDITIONS. SATURDAY NIGHT INTO SUNDAY THE COOLEST OF CONDITIONS ARE
EXPECTED WITH A H85 AIRMASS AROUND +6C. WILL LEAN A FEW DEGREES
LOWER THAN MOS GUIDANCE. FORECAST HIGHS AROUND THE MID-60S WITH LOWS
DOWN AROUND THE MID-40S. THIS GREATLY CONTRASTS MID-SEPTEMBER NORMAL
HIGHS OF AROUND THE MID-70S...WITH AROUND THE MID-50S FOR NIGHTTIME
LOWS ACROSS SOUTHERN NEW ENGLAND.

*/MONDAY INTO MONDAY NIGHT...

OPERATIONAL ECMWF/GFS EXHIBIT A CONSISTENT SIGNAL OF A REINFORCING
COLD FRONT ACROSS THE REGION. THE WESTERLY LOW- TO MID-LEVEL FLOW
SIGNALS THE ADVECTION OF A MORE CONTINENTAL AIRMASS...SO THERE IS A
LOW EXPECTATION OF WIDESPREAD RAIN AHEAD OF THE COLD FRONT. WILL PUT
IN A SLIGHT CHANCE MENTION OF SHOWERS WITH NO THUNDER. BREEZY
CONDITIONS ANTICIPATED IN PROXIMITY TO THE COLD FRONT...ESPECIALLY
WITH PASSAGE AROUND MIDDAY MONDAY OUT OF THE WEST-NORTHWEST. SHOULD
CLEAR OUT FAIRLY QUICK TOWARDS THE EVENING.

*/TUESDAY INTO THE END OF THE WEEK...

CONTINUED CONSISTENT SIGNAL BETWEEN THE OPERATIONAL ECMWF/GFS OF
RENEWED HIGH PRESSURE OUT OF CANADA BRINGING WITH IT EVEN COOLER
CONDITIONS ACROSS NEW ENGLAND WELL-BELOW NORMAL. HIGH PRESSURE LOOKS
TO BE SITUATED ACROSS NEW ENGLAND LATE TUESDAY INTO WEDNESDAY
MORNING SHIFTING EAST THEREAFTER ALLOWING RETURN SOUTHERLY FLOW AND
WARMER CONDITIONS /COULD GET BREEZY AT TIMES/. A WET WEATHER SYSTEM
IS POSSIBLE INTO NEXT WEEKEND.

&&

AFTER 06Z MVFR CIGS AND VSBYS ENTER THE AREA WITH A LOW PROB OF
IFR IN PATCHY FOG OVER SOUTHEAST MA AND RI. FOG/HAZE ALREADY
OVERSPREADING SOUTH COAST OF MA AND RI.

THURSDAY...

ANY EARLY MVFR/IFR WILL ERODE FAIRLY QUICKLY AND GIVE WAY TO VFR BY
MID MORNING. THEN LATE IN THE DAY MVFR CONDITIONS IN SCATTERED
SHOWERS AND TSTMS FROM WEST TO EAST.

THURSDAY NIGHT...

MVFR BECOMES WIDESPREAD WITH EMBEDDED IFR POSSIBLE AS NUMEROUS
SHOWERS AND TSTMS OVERSPREAD THE AREA FROM WEST TO EAST. HEAVY RAIN
