AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
1157 AM EDT FRI JUN 27 2008

.SYNOPSIS...
AN UNUSUALLY STRONG UPPER LEVEL LOW PRESSURE SYSTEM OVER THE GREAT
LAKES WILL TRANSPORT WARM AND HUMID WEATHER INTO SOUTHERN NEW
ENGLAND THROUGH EARLY NEXT WEEK.  THIS ALSO WILL RESULT IN SEVERAL
ROUNDS OF STRONG TO SEVERE THUNDERSTORMS THAT WILL BRING TORRENTIAL
RAINFALL AND PROBABLY SOME URBAN AND POOR DRAINAGE STREET FLOODING.
DRIER WEATHER SHOULD RETURN TO THE REGION BY THE MIDDLE OF NEXT WEEK
AS THE UPPER LEVEL SYSTEM FINALLY LIFTS OFF TO THE NORTHEAST.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
MWN 11AM WET BULB OF 52F SUGGESTS NR 90 BOS/BDL METRO AREAS. 12Z ALB
SOUNDING REVIEWED. PRESUMING OUR ASSESSMENT THAT WE PASS 88F... WE SHOULD
DO WELL ON HEAVY CONVECTION. THE ONE FLY IN THE OINTMENT WOULD BE TOO
MUCH CLOUD COVER. ATTM...MID LVL MOISTURE POOL MOVING ENE FROM N PA
AND NYS INTO SNE ALONG AND S OF MA PIKE DURING FORENOON SHOULD THIN
OUT.

THE INITIAL FOCUS IS N OF THE MASS PIKE EARLY MID AFTN AND THEN
SINKING INTO AN AXIS VCNTY BDL-PYM BETWEEN 4PM AND 7 PM.

12Z GFS CONTINUES RATHER BULLISH. I MAY BE WRONG AND TOO AGGRESSIVE
ON THE POTENCY DUE TO CLOUD COVER BUT ATTM WE ARE SETTING UP FOR SVR
WX OPS MID AFTN.

SKYWARN SHOULD BE IN THE OFFICE FOR A 130PM START FOR POTENTIAL SVR
CONVECTION.

88F IS THE TRIGGER TEMP.

THIS APPEARS TO BE PRIMARILY AN AFTERNOON/EARLY EVENING EVENT WITH
INITIATION SOMEWHERE N MA OR S NH AND OUTFLOWS CASTING ESEWD PER THE
500 AND 300 UPPER LVL FLOW. THAT WOULD/SHOULD PUSH THE HEAVIEST
CONVECTION S OF THE MASS PIKE AROUND 5PM.

WE HAVE SEEN THE SPC WRF FROM THE 00Z RUN WHICH HAS QUITE A NE-SW
ORIENTED BAND OF HEAVY CONVECTION ROLLING ARCED BOS-HVN AT 21Z. AM
NOT WITH HIGH CONFIDENCE ON THIS SPECIFIC OUTPUT...SOMETIMES ITS VERY
GOOD...SOMETIMES NOT...BUT IN TANDEM WITH THE GFS SIGNALS...WARRANTS
CONSIDERATION.

AFTER 00Z THE POTENTIAL BIGGER TROUBLE SHOULD BE WELL OFF THE COAST
WITH FOCUS MAYBE LAGGING S COAST DURING THE NIGHT BUT AM NOT OVERLY
ENTHUSIASTIC ABOUT ANY SVR CONVECTION AFTER 00Z /MANY MWSS AND OR
SMWS/.

SO WHILE WIND FIELDS AOB 500MB ARE MARGINAL /30KTS/...STEEP LAPSE RATES
INCLUDING LARGE EQUIV POTENTIAL TEMP LAPSE RATES...MAYBE WEAK
ROTATION /STM MOTION ESEWD ARD 20 KTS/ WITH TT NR 50 SHOULD BE ENOUGH TO
CAUSE SCT STRONG TO SVR STORMS.

PER ANALYSIS OF THE ALB 12Z SOUNDING USING 90/67 WBZ NR 12K...ZL
12.8 EL 41K TROP 43K AND CLOUD TOP 50K. ANY VIL OVER 50 WILL NEED TO
BE CLOSELY MONITORED.

PRECIPITABLE WATER VALUES ARE FORECAST AT 1.5 TO 1.9 SO HEAVY DOWNPOURS
ARE POSSIBLE...WITH LOCAL STREET FLOODING POSSIBLE IN POOR DRAINAGE
AREAS.

SINCE FREEZING LEVEL AND WET BULB ZERO LEVEL ARE BETWEEN 12K AND 13K
FEET. THIS IS A TAD HIGH FOR HAIL. STRONG WIND GUSTS ARE MORE LIKELY
ESPECIALLY IN ANY WATER-LOADED STORMS.

AN AIR QUALITY ALERT HAS BEEN ISSUED FOR A PART OF SOUTHEAST
MASSACHUSETTS AND S RI.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/...
TONIGHT...WHERE DOES THE COLD FRONT STALL. SOME OF THE MODELS TONIGHT
SUGGEST A STALL NORTH OF THE MASS PIKE. BUT THERE IS ENOUGH NORTHWEST
FLOW ALOFT THIS EVENING TO PUSH THE FRONT TO THE SOUTH COAST. EITHER
WAY...CLOUDS LINGER THROUGH THE FIRST PART OF THE NIGHT AS WELL AS
SCATTERED SHOWERS/ISOLATED TSTMS. MODELS SUGGEST A SECOND SURGE OF
RAINFALL OVERNIGHT...PEAKING AROUND 2 AM SATURDAY BUT CONFIDENCE IS
VERY LOW ON THIS SECONDARY PULSE.

WITH PLENTY OF WET GROUND AND A WEAK WIND FIELD...AND LITTLE DRYING
OF THE HUMID AIR...WE EXPECT ANOTHER FOGGY NIGHT ALL AROUND SOUTHERN
NEW ENGLAND.

SATURDAY...
ANY LEFT OVER CONVECTION FROM A POSSIBLE MCS SHOULD HAVE EXITED THE
SOUTHEAST NEW ENGLAND COAST BY EARLY SATURDAY MORNING.
OTHERWISE...THE NAM/ECMWF/UKMET ARE FAIRLY AGGRESSIVE WITH THE
BACKDOOR COLD FRONT WHILE THE GFS IS NOT SO MUCH.  HOWEVER...WILL
LEAN TOWARDS MODEL CONSENSUS AND BRING THE BACKDOOR FRONT THROUGH
THE COASTAL PLAIN.  THEREFORE...WILL TREND HIGHS FROM THE 70S ALONG
THE IMMEDIATE EASTERN MA COAST TO THE UPPER 80S IN THE CONNECTICUT RIVER
VALLEY.

AS FOR CONVECTIVE CHANCES...ANOTHER SHORTWAVE LOOKS TO APPROACH FROM
THE WEST DURING THE AFTERNOON.  MODELS NOT THAT AGGRESSIVE WITH QPF
AND THAT IS PROBABLY BECAUSE THE SHORTWAVE DOES NOT ARRIVE UNTIL MID
TO LATE AFTERNOON.  HOWEVER...SURFACE DEWPOINTS AROUND 70 ACROSS THE
INTERIOR WHICH SHOULD RESULT IN A FAIR AMOUNT OF LOW LEVEL
INSTABILITY.  THEREFORE...WILL GO WITH CHANCE POPS TO THE FROM THE
LATE AFTERNOON AND INTO THE EVENING FOR SCATTERED
SHOWERS/THUNDERSTORMS NORTHWEST OF I-95 WITH THE BEST CHANCE ACROSS
SOUTHWEST NH...WESTERN MA...CONNECTICUT.  WIND FIELDS COULD BE
BETTER...BUT THERE SHOULD BE ENOUGH CAPE TO BRING THE POTENTIAL FOR
AT LEAST A FEW SEVERE THUNDERSTORMS TO THE INTERIOR.  IN
ADDITION...HIGH PWATS WILL BRING THE POTENTIAL FOR LOCALLY HEAVY
RAINFALL WITH ANY OF THE ACTIVITY THAT DEVELOPS.  ALONG THE COASTAL
PLAIN...WILL CARRY JUST SLIGHT CHANCE POPS AS THE STABILIZING MARINE
LAYER MAY LIMIT CONVECTIVE POTENTIAL.

SATURDAY NIGHT...
CONTINUED WARM ADVECTION AND ELEVATED INSTABILITY SHOULD A THREAT OF
SCATTERED SHOWERS/THUNDERSTORMS OVERNIGHT...ALTHOUGH THIS ACTIVITY
WILL BE HIT AND MISS AND MOST OF THE NIGHT IT MAY END UP DRY.  THE BEST
CHANCE LOOKS TO BE OVER THE NORTHWEST SECTIONS AND THAT IS WHERE WE
WILL RUN WITH LIKELY POPS AND TAPER TO LOW CHANCE ON THE COASTAL PLAIN.
WITH THE LOSS OF DAYTIME HEATING...WE SHOULD SEE THE BACKDOOR COLD
FRONT PUSH FURTHER WEST THROUGH MUCH OF OUR REGION.  WITH VERY HIGH
DEWPOINTS IN PLACE WE MAY SEE AREAS OF DENSE FOG DEVELOP BRINING
POOR VISIBILITIES TO MUCH OF THE REGION.  LOWS SHOULD MAINLY BE IN
THE 60S.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
SUNDAY...
THE BACKDOOR COLD FRONT LOOKS TO WASHOUT AS DEEP
MERIDIONAL FLOW CONTINUES BRINGS COPIOUS AMOUNTS OF LOW LEVEL
MOISTURE INTO OUR REGION. DEWPOINTS MAY EXCEED 70 ACROSS PORTIONS OF
OUR REGION. SEVERAL SHORTWAVE DISTURBANCES WILL BRING SEVERAL ROUNDS
OF SHOWERS/THUNDERSTORMS TO THE REGION. AGAIN...THE BULK OF THE
ACTION LOOKS TO BE FOCUSED ACROSS THE INTERIOR CLOSER TO THE BETTER
DYNAMICS AND INSTABILITY. WILL RUN WITH HIGH END LIKELY POPS ACROSS
THE INTERIOR...AND TAPER TO CHANCE ALONG THE COASTAL PLAIN. ANY
SHOWERS/THUNDERSTORMS WILL BRING THE POTENTIAL FOR TORRENTIAL
RAINFALL AND LOCALIZED FLOODING ACROSS THE INTERIOR. THERE IS ALSO
THE POTENTIAL FOR MORE SEVERE WEATHER TO THE NORTHWEST OF I-95 WITH
GOOD WIND FIELDS AND DEEP LOW LEVEL MOISTURE. THE PRIMARY SEVERE
WEATHER RISK WILL BE DAMAGING WET MICROBURSTS. WHETHER OR NOT THIS IS
REALIZED WILL DEPEND ON THE AMOUNT OF INSOLATION WE SEE. WE DO EXPECT
A FAIR AMOUNT OF CLOUDINESS AROUND FOR MUCH OF THE DAY...BUT IF WE
CAN MUSTER A FEW PEEKS OF SUNSHINE IT WONT TAKE MUCH TO DESTABILIZE
WITH 70+ DEWPOINTS SO THE SEVERE WEATHER POTENTIAL ACROSS THE
INTERIOR WILL HAVE TO BE MONITORED. WE BLENDED MAV/MET TEMPERATURES
AND EXPECT HIGHS MAINLY IN THE UPPER 70S TO LOWER 80S.

SUNDAY NIGHT...
WILL HAVE LIKELY POPS ACROSS MOST OF THE REGION FOR THE CONTINUED
POTENTIAL OF SHOWERS AND THUNDERSTORMS.  HEAVY RAINFALL AND
LOCALIZED FLOODING WILL CONTINUE TO BE A CONCERN ACROSS THE INTERIOR
AS THE UPPER LEVEL SYSTEM IS VERY SLOW MOVING AND THE ATMOSPHERE
WILL BE JUICED.

MONDAY AND TUESDAY...
WILL CONTINUE WITH A CHANCE OF POPS FOR SHOWERS AND THUNDERSTORMS AS
UPPER LEVEL TROUGH REMAINS TO OUR WEST.  WE MAY THE BULK OF THE
PRECIPITATION BEGIN TO SHIFT TOWARDS THE COASTAL PLAIN AS THE SYSTEM
VERY SLOWLY INCHES TO THE EAST AND WE ALSO BEGIN TO LOSE OUR REAL
DEEP MOISTURE.

WEDNESDAY AND THURSDAY...
UPPER LEVEL TROUGH FINALLY LIFTS OFF TO THE NORTHEAST.  IT SHOULD
MAINLY BE DRY...BUT ANOTHER APPROACHING COLD FRONT LATE THURSDAY MAY
TRIGGER A FEW AFTERNOON/EVENING SHOWERS/THUNDERSTORMS.  JUST WENT
WITH SLIGHT CHANCE POPS FOR NOW SINCE ITS 7 DAYS OUT AND WE HAD SO
MUCH UPCOMING WEATHER DID NOT HAVE TIME TO ANALYZE THIS TOO MUCH.
HIGHS SHOULD MAINLY BE IN THE 80S AWAY FROM THE IMMEDIATE SOUTH
COAST/CAPE/ISLANDS.

&&

.AVIATION /16Z FRIDAY THROUGH TUESDAY/...
VFR HAZY THIS AFTERNOON MVFR/IFR IN SCATTERED THUNDERSTORMS...CONTINUING
THROUGH THE FIRST HALF OF TONIGHT. WET GROUND-LIGHT WIND-MOIST AIR WILL
COMBINE FOR SOME PATCHY FOG LATER TONIGHT.

OUTLOOK...SATURDAY THROUGH TUESDAY...

VFR CONDITIONS WILL BE MIXED WITH TIMES OF MVFR/IFR IN ROUNDS OF
SHOWERS/THUNDERSTORMS...PARTICULARLY ACROSS THE INTERIOR. IN
ADDITION...AREAS OF PATCHY DENSE FOG PARTICULARLY DURING THE
OVERNIGHT HOURS WILL RESULT IN SOME MVFR/IFR CONDITIONS AND THIS
WILL BE MOST PREVALENT ALONG THE COAST.

&&

.MARINE...
TODAY AND TONIGHT...TSTMS DEVELOPING THIS AFTERNOON AND MOVING ACROSS
THE WATERS. OVERALL WINDS AND SEAS LOOK TO STAY BELOW SMALL CRAFT
THRESHOLDS...BUT WITH 5 FOOT SEAS ON THE BORDER OF OUR SOUTHERN OUTER
WATERS. ISOLATED SMW STORMS FOR 35 OR 40 KTS ANTICIPATED BOS HARB TO
NARR BAY INCLUDING W PART OF CAPE COD BAY 4PM-8PM.

OUTLOOK...SATURDAY THROUGH TUESDAY...

WNA APPEARS TO BE SUFFERING A CONTINUED PROBLEM OF OVER FORECASTING
WAVE HEIGHTS WITH AN INVERSION OVER THE COOL OCEAN.
NONETHELESS...SCA CONDITIONS ARE POSSIBLE ACROSS THE SOUTHERN OUTER
WATERS LATE THIS WEEKEND INTO EARLY NEXT WEEK WITH A PERSISTENT
SOUTH TO SOUTHWEST FLOW. WE MAY SEE SCA WIND GUSTS ACROSS THE WATERS
LATER SUNDAY INTO MONDAY AS LOW LEVEL JET INCREASES.
REGARDLESS...FEEL WNA MODEL IS TOO HIGH WITH THE SEAS OVER THIS
PERIOD AND UNDERCUT THEM. THE OTHER CONCERN WILL BE FOR AREAS OF
DENSE FOG AT TIMES.  THIS A RESULT OF DEEP MOISTURE OVER RUNNING THE
COOL OCEAN.

&&

.HYDROLOGY...
PRECIPITABLE WATER VALUES INCREASE TO THE 1.5 TO 1.8 INCH RANGE BY
THIS AFTERNOON. THIS WILL SUPPORT SOME HEAVY DOWNPOURS. GENERAL
FLOODING LOOKS DIFFICULT AS AREAL FLOODING VALUES ARE 2-3 INCHES IN
ONE HOUR AND 3-4.5 INCHES IN 3 HOURS. HOWEVER THE JUICINESS OF THE
AIRMASS COULD STILL LEAD TO LOCALLY HEAVY DOWNPOURS THIS AFTERNOON AND
EARLY TONIGHT THAT COULD BRING URBAN AND POOR DRAINAGE FLOODING.
