Flash Flooding and Hail in Massachusetts, July 8, 2011

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
730 AM EDT FRI JUL 8 2011

.SYNOPSIS...
A FRONT WILL REMAIN STALLED ALONG THE SOUTH COAST OF NEW ENGLAND
TODAY. A LOW PRESSURE WILL MOVE ALONG THIS FRONT AND PASS SOUTH
OF NEW ENGLAND TONIGHT AND EARLY SATURDAY. HIGH PRESSURE RETURNS
BRIEFLY FOR SATURDAY NIGHT INTO EARLY MONDAY. A COLD FRONT SHOULD
GRADUALLY SLIDE THROUGH THE REGION THROUGH TUESDAY...BRINGING A
CHANCE OF SHOWERS AND THUNDERSTORMS. HIGH PRESSURE RETURNS
WEDNESDAY INTO THE END OF THE WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
MID-LEVEL INSTABILITY HAS INCREASED...AND STARTING TO SEE SIGNS OF
GOOD MOISTURE LOW-LEVEL MOISTURE TRANSPORT. DEW POINTS ALONG THE
SOUTH COAST...WHICH IS WHERE A STALLED FRONT WAS LOCATED EARLY
THIS MORNING...HAVE CLIMBED TO NEAR 70F. LATEST MESOANALYSIS FROM
SPC SHOWING 20 KTS OF EFFECTIVE BULK SHEAR...WHICH HAS TURNED OUT
TO PROVIDE ENOUGH ORGANIZATION TO GENERATE ISOLATED SHOWERS AND
THUNDERSTORMS THIS MORNING.

GIVEN THE CONVECTIVE NATURE OF THE PRECIPITATION THIS MORNING...
HAVE LOW CONFIDENCE IN TIMING AND COVERAGE FOR ANY SPECIFIC
LOCATION...ESPECIALLY THIS MORNING. WILL SLOWLY RAMP UP RAINFALL
CHANCES IN THIS FORECAST TO LIKELY AROUND NOON...MAINLY SOUTH OF
THE MASS PIKE. TEMPERATURES WILL BE SIGNIFICANTLY LOWER TODAY
COMPARED TO THE PAST SEVERAL...BUT THE COMBINATION OF ELEVATED
INSTABILITY AND PROXIMITY OF A STALLED FRONT...SHOULD BE
SUFFICIENT TO TRIGGER CONVECTION LATER TODAY.

USED A BLEND OF THE GUIDANCE FOR TEMPERATURES...BUT MODIFIED
GUIDANCE DEW POINTS TO BRING THEM UP QUICKER.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/...
A MID-LEVEL SHORTWAVE CROSS OUR REGION THIS EVENING...AND WILL
LIKELY GENERATE A WEAK SURFACE WAVE ALONG THE FRONTAL BOUNDARY
AS IT MOVES BY. NOT VERY CONFIDENT IN THE DETAILS OF SUCH A WEAK
FEATURE. AS SUCH...USED A BLEND OF THE GFS AND NAM TO PROVIDE SOME
TIMING.

DRIER WEATHER RETURNS FOR SATURDAY AS A HIGH PRESSURE ARRIVES FROM
SOUTHERN CANADA AND FINALLY PUSHES THIS FRONT OFFSHORE.

USED A BLEND OF THE GUIDANCE FOR TEMPERATURES.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
MAIN POINTS...
*COOLER AND DRIER WEATHER ASSOC WITH HIGH PRES FOR SUNDAY
*COLD FRONT WITH SHOWERS AND THUNDERSTORMS MONDAY INTO TUESDAY
*UNSEASONABLY COOL WEATHER BEGINNING WEDNESDAY INTO THE END OF THE WEEK
*ANOTHER WET WEATHER SYSTEM POSSIBLE INTO THE WEEKEND

OVERVIEW...
0Z NAM HAS FINALLY COME INTO CONSENSUS WITH MDL SOLNS...MORESO WITH
THE OUTCOMES FCST BY THE GFS FOR THE LAST SEVERAL DAYS CONCERNING
SHRTWV ENERGY THRU THE SRN BRANCH OF THE MID-LVL TROF INTO THE END
OF THIS WEEK USHERING CYCLOGENESIS OFF THE SHORELINE OF THE DELMARVA
PENINSULA AND ELONGATING ALONG THE STALLED QUASI-STATIONARY FRONTAL
BOUNDARY S OF NEW ENGLAND. AS SUCH FOR THE EXTENDED PD PLACED
GREATER WEIGHT UPON THE 0Z GFS...WHILE TAKING INTO CONSIDERATION THE
CONSISTENT NATURE OF THE ECMWF. WEIGHTED MORESO WITH BIAS-CORRECTED
MAV GUIDANCE TRANSITIONING TO THE BIAS-CORRECTED MOS GUIDANCE.

DETAILS...

SATURDAY NIGHT THRU SUNDAY NIGHT...
SFC HIGH PRES SETTLES ACROSS THE RGN SATURDAY NIGHT INTO SUNDAY
MORNING...GRADUALLY PROGRESSING E INTO SUNDAY NIGHT...ALLOWING FOR A
PERIOD OF SEASONABLY/DRY WX. LGT/VRB SFC FLOW COUPLED WITH NVA-
SUBSIDENCE AND MUCH DRIER /SLIGHTLY COOLER/ AIR WILL MAKE FOR A GOOD
CASE OF NOCTURNAL COOLING AT THE SFC FOR SUNDAY MORNING LOWS.
EXPECTING LOW SFC DEWPOINTS ATTENDANT WITH THE SFC HIGH PRES WILL
ALLOW FOR MINS TO FALL INTO THE MID-UPR 50S ACROSS THE N/W NH AND
MA...INTO THE LOW 60S FURTHER S AND CLOSER TO SHORE. SUNDAY WILL SEE
RETURN ONSHORE SFC SLY FLOW AS THE SFC HIGH SHUNTS E...WITH SW FLOW
AT MID-LVLS ADVECTING WARM AND MOIST AIR OVER THE RGN. SFC S FLOW
MAY BE LIGHT ENOUGH TO ALLOW SEA-BREEZES ALONG THE E SHORELINE.
OTHERWISE EXPECT WITH THE MOISTURE RETURN FOR SOME CU DVLPMNT
TOWARDS THE AFTN...YET ANTICYCLONIC FLOW WILL STILL BE PREVALENT
EXPECT SCT /RATHER THAN BKN/ CU MIXING UP TO H85/5-7 KFT...
ESPECIALLY ALONG W SLOPES OF TERRAIN WHERE MID-LVL MOIST AND Q-VECT
CONV MAY BE BETTER DEFINED. RETURN OF H925 TEMPS TO +18-20C SHOULD
ALLOW SFC TEMPS TO REBOUND INTO THE UPR 70S/LOW 80S. SUNDAY NIGHT
WILL CONTINUE TO SEE CONTINUED WARMING/MOISTENING AT MID-LVLS AIDED
BY W/SW FLOW ALOFT. SHOULD BE A SLIGHTLY WARMER NIGHT IN TERMS OF
MINS AS MID-UPR LVL CLOUDS WILL LIKELY BE STREAMING ACROSS THE RGN
ALONG THE MEAN LYR FLOW AHEAD OF THE NEXT SYS FOR THE BEGINNING OF
THE WEEK.

MONDAY THRU TUESDAY NIGHT...
MATURATION PHASE OF LOW PRES ACROSS ERN CANADA WILL AMPLIFY THE E-W
THERMAL AXIS/H3 JET STREAK IN PROXIMITY OF THE N GRT LKS RGN INTO N
NEW ENGLAND THEREBY AMPLIFYING ATTENDANT SHRTWV DISTURBANCES ALONG
THE MEAN LYR FLOW. ALTHO MDL DISCREPANCIES EXIST AMONGST THE GFS/
ECMWF IN HANDLING THE AFOREMENTIONED FEATURES...THERE IS AGREEMENT
UPON A GENERAL TREND IN WHERE SHRTWV DISTURBANCES SHOULD AT LEAST
PROVIDE ENHANCED ASCENT OF AVAILABLE MOISTURE/INSTABILITY THAT HAS
BEEN PUMPED ACROSS THE RGN ALONG THE WRN PERIPHERY OF THE DEPARTING
SFC HIGH PRES...WITH BETTER DYNAMICS CONFINED TO N NEW ENGLAND
MONDAY NIGHT INTO TUESDAY. HAVE GREATER CONFIDENCE IN 0Z GFS
OUTCOME...AMPLIFICATION OF SHRTWV ENERGY THRU N NEW ENGLAND SHOULD
DRAG COOLER AIR SEWD ALONG AND BEHIND A COLD FRONT...ESPECIALLY AT
MID-LVLS...WHICH SHOULD PROVIDE ENOUGH FRONTOGENETICAL FORCING OF
WARM/MOIST UNSTABLE AIR ALONG AND AHEAD. TIMING OF THIS FRONTAL
BOUNDARY REMAINS STILL IN QUESTION...AND WHETHER INSTABILITY ALONG
AND AHEAD WILL BE SFC BASED. SHOULD CONVECTION FIRE IN THE VICINITY
OF THE E GRT LKS AND PROGRESS E WITH THE COLD FRONT MON AFTN
CONTINUING INTO TUE...NOT CERTAIN IF SFC DESTABILIZATION WILL
OCCUR WITH POTENTIAL CLOUD COVER OVERSPREADING THE RGN FROM THE W.
DETAILS ARE STILL SKETCHY AT THIS TIME...NEVERTHELESS FEEL BEST POP
CHS FOR SHOWERS/THUNDERSTORMS WILL BE ON TUESDAY INTO TUESDAY NIGHT
AS WARM/MOIST UNSTABLE AIR...AIDED BY STRONG AND POTENTIALLY GUSTY
SW FLOW...WILL BE READILY AVAILABLE ALONG AND AHEAD OF THE EXPECTED
COLD FRONT.

WEDNESDAY INTO THE END OF THE WEEK...
MDL SOLNS CONTINUE TO HIGHLIGHT A STRONG SFC HIGH PRES RIDGE IN
CONTROL OF THE RGNS WX BRINGING COOLER AND MUCH DRIER CONDITIONS TO
THE RGN. INITIALLY MODEST N/NW FLOW...WITH GUSTS 20-25 KTS...BEHIND
THE EXITING SYS WILL USHER SOME VERY COOL MID-LVL AIR SEWD WITH H925
TEMPS AS +10C. WILL SEE MIN TEMPS FALL INTO THE LOW TO MID 50S...
WARMER ALONG THE SHORE. SOME AREAS REPORTING UPR 40S FOR MINS
WED/THURS MORN IS NOT OUT OF THE QUESTION. MAX TEMPS FOR THESE TWO
DAYS WILL RANGE IN THE LOW TO MID 70S...COOLER ALONG THE SHORE. VERY
UNSEASONABLE WX! WILL SEE LGT/VRB NLY FLOW ON THURS GRADUALLY VEER
OUT OF THE S/SW BY FRIDAY...SO THEREAFTER EXPECT A GRADUAL WARMING
TREND ALONG AND AHEAD OF ANOTHER WET WX SYS FOR THE WEEKEND.
ANTICIPATE MOSTLY CLEAR CONDITIONS FOR MUCH OF THE TIMEFRAME...
PERHAPS DIURNAL CU DURING THE DAY WEDNESDAY...WITH INCREASING CLOUDS
RETURNING INTO LATE FRI INTO SAT.

SLOWLY VEERING OUT OF THE S/SW INTO SUNDAY NIGHT. COULD STILL SEE
SOME RESIDUAL FOG THRU THE OVRNGT HRS FOR THE WEEKEND ALONG THE SE
TERMINALS OUT ALONG THE CAPE/ISLANDS. LOW CONFIDENCE AT THIS TIME.

MONDAY INTO TUESDAY NIGHT...
MEDIUM CONFIDENCE VFR/MVFR. ANOTHER COLD FRONT APPROACHING THE
TERMINALS ALONG AND AHEAD OF WHICH SHRA/TSRA WILL DEVELOP. FEEL LOW
VSBY/CIG IMPACTS WILL BE PRIMARILY SUITED FOR THE N/W TERMINALS
MONDAY...TRANSITIONING SEWD TOWARDS SE NEW ENGLAND INTO TUESDAY.
S/SW FLOW GUSTING AT TIMES 15 TO 20 KTS PSBL. ANY TSRA IMPACTING
THE TERMINALS WILL LIKELY RESULT IN TEMPO IFR/LIFR VSBYS AND CIGS.
SIGNIFICANT WEATHER SHOULD BE THRU THE TERMINALS BY TUESDAY NIGHT.

&&

.MARINE...
WINDS AND SEAS EXPECTED TO REMAIN BELOW SMALL CRAFT ADVISORY
THRESHOLDS THROUGH TONIGHT. AREAS OF FOG AND LOW CLOUDS WILL
RESULT IN POOR VSBYS...MAINLY ACROSS THE SOUTHERN COASTAL WATERS
FOR A PORTION OF THIS MORNING. THE PASSAGE OF A WEAK SURFACE LOW
AND THE ARRIVAL OF A STRONG SOUTHERLY SWELL SATURDAY IS EXPECTED
TO BUILD SEAS TOWARDS 5 FT ACROSS THE OUTER SOUTHERN COASTAL
WATERS.

OUTLOOK...SATURDAY NIGHT THROUGH TUESDAY NIGHT...

SATURDAY NIGHT INTO SUNDAY NIGHT...
SEAS OF AROUND 5 TO 6 FEET WILL CONTINUE ACROSS THE S OPEN WATERS AS
A RESULT OF SWELL GENERATED BY SLY WINDS S OF A STATIONARY FRONTAL
BOUNDARY DRAPED S OF NEW ENGLAND. ANTICIPATE SEAS BELOW SCA
THRESHOLDS BY SUNDAY.

MONDAY INTO TUESDAY NIGHT...
A COLD FRONT APPROACHES THE REGION ALONG AND AHEAD OF WHICH S/SW
WINDS WILL INCREASE...WITH GUSTS UP TO 25 KTS POSSIBLE PRIMARILY FOR
TUESDAY. WILL SEE SEAS BUILD IN CONCERT WITH STRONG AND GUSTY SW
