AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
809 PM EDT WED MAY 16 2012

.SYNOPSIS...
SCATTERED SHOWERS AND A FEW THUNDERSTORMS ARE EXPECTED AHEAD OF A
COLD FRONT INTO THIS EVENING...MAINLY ACROSS WESTERN NEW ENGLAND.
THE COLD FRONT WILL THEN BRING DRY WEATHER FROM THU INTO THE
WEEKEND ALONG WITH A WARMING TREND. UNSETTLED WEATHER MAY RETURN
TO SOUTHERN NEW ENGLAND EARLY NEXT WEEK.

&&

.NEAR TERM /UNTIL MIDNIGHT TONIGHT/...
***A FEW STRONG TO SEVERE THUNDERSTORMS ARE POSSIBLE ACROSS THE
 INTERIOR THIS EVENING***

***SEVERE THUNDERSTORM WATCH IS IN EFFECT FOR PORTIONS OF NORTHERN
 CONNECTICUT...WESTERN-CENTRAL MASSACHUSETTS...AND SOUTHERN NEW HAMPSHIRE
 UNTIL 10 PM***

815 PM UPDATE...

HAVE EXPANDED THE SVR TSTM WTCH TIL 10 PM AND AREAL EXTENT
EASTWARD INTO WORCESTER COUNTY...NORTHWEST MIDDLESEX COUNTY AND
HILLSBORO COUNTY OF SOUTHWEST NH. REASONING IS A MESO COLD POOL
HAS DEVELOPED WITH EARLIER CONVECTION AND THIS WILL LIKELY SUSTAIN
CONVECTION EASTWARD AS WELL AS DURATION. STORMS ARE MINI
SUPERCELLS WITH PERSISTENT MID LEVEL ROTATION...ALBEIT WEAK
ROTATION. SFC DEW PTS IN THE L60S CONTINUE TO ADVECT NORTHWARD
ACROSS THE REGION ALONG WITH SFC TEMPS NEAR 70 COMBINED WITH H5
TEMPS OF -16C. THESE PARAMETERS ARE YIELDING ML CAPES ON THE ORDER
OF 1500 J/KG ACROSS NORTHWEST MA INTO SOUTHWEST NH ALONG WITH DEEP
LAYER SHEAR OF 40 KT COMBINED WITH MID LEVEL LAPSE RATES OF AROUND
6.5C/KM. THIS SHOULD SUSTAIN STRONG TO PERHAPS SVR TSTMS TIL 10 PM
ACROSS NORTHWEST-CENTRAL MA INTO SOUTHWEST NH.

THE MAIN THREATS CONTINUE TO BE STRONG TO DAMAGING WINDS ALONG
WITH LARGE HAIL. STORMS WILL WEAKEN AFTER 10 PM.

MAY NEED TO ISSUE A DENSE FOG ADVISORY FOR RI AND SOUTHEAST MA AS
PREFRONTAL AIRMASS IS BECOMING SATURATED AS BLYR COOLS. VSBYS WILL
IMPROVE 06Z-09Z WITH THE FRONTAL PASSAGE.

&&

.SHORT TERM /MIDNIGHT TONIGHT THROUGH THURSDAY NIGHT/...
TONIGHT...

THE COLD FRNT ITSELF SHOULD BE OFFSHORE AFTER MIDNIGHT BY WHICH
POINT COOLER AND DRIER AIR ADVECTED BY W/NWLY FLOW WILL FOLLOW.
THERE IS THE POSSIBILITY FOR FOG DEVELOPMENT ALONG THE S/SE COAST
AHEAD OF THE COLD FRNT INITIALLY...LIKELY TO DISSIPATE INTO THE
EARLY MORNING HRS AS W/NW FLOW BRINGS IN DRIER AIR AT THE SFC.
SHOULD BE A MILD NGT MORESO FOR THE S/E...WHILE N/W WHICH WILL SEE
CLEARING CONDITIONS AFTER MIDNIGHT INTO MORNING WILL FALL INTO THE
MID 40S.

THURSDAY AND THURSDAY NIGHT...

NW FLOW THRU THE DAY WITH MOSTLY CLEAR CONDITIONS. CANT RULE OUT
SOME DIURNAL SCTD CU...BUT THE ABUNDANCE OF COOLER AND DRIER AIR
PUSHING INTO THE RGN WILL LIKELY MIX-DOWN AND MIX-OUT THE LOWER
ATMOS. LOW RH VALUES AT THE SFC. MAY ALSO SEE A FEW MINOR GUSTS
AROUND 15 MPH. H85 TEMPS FALLING DOWN TO AROUND +3C...SO HIGH TEMPS
INTO THE LOW 70S IS PSBL. SEA BREEZES ANTICIPATED NEAR THE WATERS
DUE TO THE LIGHT W/NW FLOW. OVRNGT...HIGH PRES PUSHING ACROSS THE
RGN WILL LEND TO LGT WINDS AND CONTINUED CLEAR CONDITIONS.
NOCTURNAL COOLING LIKELY. TEMPS TO W MA INTO S NH SHOULD FALL INTO
THE MID 30S SO FROST WILL BE PSBL...WITH LOW- MID 40S ELSEWHERE.
FROST HEADLINES MAY BE NECESSARY.

&&

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

* DRY WITH MODERATING TEMPERATURES THROUGH SUN
* SHOWERS POSSIBLE MON INTO WED

WILL BE BRIEF GIVEN THE EXPECTED CONVECTION THIS AFTERNOON AND
EVENING ACROSS WESTERN NEW ENGLAND. NICE WEATHER REMAINS IN THE
FORECAST FROM FRI INTO THE WEEKEND AS LOW AMPLITUDE MID LEVEL
TROUGHING OVER THE NORTHEAST FRI IS REPLACED BY BUILDING MID LEVEL
RIDGE OVER THE OH VLY AND EVENTUALLY THE NORTHEAST THIS WEEKEND.
THIS WILL PROVIDE LARGE SCALE SUBSIDENCE OVER SOUTHERN NEW ENGLAND
YIELDING DRY WEATHER ALONG WITH WARM MAY SUNSHINE. EXPECT MILD DAYS
AND COOL NIGHTS WITH HIGHS IN THE 70S TO NEAR 80 INLAND SAT AND SUN.
SEABREEZES EXPECTED ALL THREE DAYS GIVEN PROXIMITY OF HIGH PRES AND
ASSOCIATED LIGHT PGRAD. THUS COOLER ALONG THE IMMEDIATE SHORE.
NONETHELESS NICE MAY-LIKE WEATHER EXPECTED.

BY NEXT WEEK FORECAST CONFIDENCE DECREASES RAPIDLY AS MODELS DIFFER
ON THE MAGNITUDE OF TROUGHING LEFT BEHIND OVER THE GULF STATES AND
THE EVOLUTION OF THIS TROUGH POTENTIALLY UP THE EASTERN SEABOARD. AT
84 HRS THE 12Z GFS DOESN/T HAVE SUPPORT FROM THE 12Z NAM/00Z ECMWF
AND UKMET...WHICH ALL HAVE MORE TROUGHING OVER THE GULF STATES THAN
THE 12Z GFS. THEREAFTER THE 00Z ECMWF AND NOW THE NEW 12Z UKMET BOTH
INDICATE A MID LEVEL TROUGH OR CLOSED LOW POTENTIALLY COMING UP THE
EASTERN SEABOARD IN RESPONSE TO BUILDING WESTERN ATLC RIDGE. THE GFS
ONLY OFFERS A FRONTAL PASSAGE AROUND THE TUE TIMEFRAME. FORECAST
CONFIDENCE IS BELOW AVERAGE HERE GIVEN THE TIME RANGE AND MODEL
SPREAD BUT GIVEN THE UKMET AND THE ECMWF ARE CLOSE...WE WILL FOLLOW
A NON-GFS SOLUTION HERE WITH CHANCE POPS FROM MON INTO WED. THIS IS
CLOSE TO OUR PREVIOUS FORECAST AS WELL.

IN ADDITION DID BRING HIGHS DOWN A NOTCH MON-WED GIVEN POTENTIAL
CLOUD COVER AND PRECIP ALONG WITH ONSHORE FLOW. BLENDED THE 2 METER
TEMPS FROM THE ECMWF TO ACCOMPLISH THIS. OVERALL NOT MUCH CHANGE
FROM OUR PREVIOUS FORECAST.

&&

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
FORECASTER CONFIDENCE LEVELS...
  LOW...LESS THAN 30 PERCENT
  MODERATE...30 PERCENT TO 60 PERCENT
  HIGH...GREATER THAN 60 PERCENT

OVERVIEW...

TONIGHT...TWO AREAS OF CONCERN THIS EVENING...FIRST TSTMS OVER
NORTHWEST MA AND SOUTHERN VT. THESE STORMS SHOULD HOLD TOGETHER
THRU 01Z AND TRACK NE...PASSING CLOSE TO MHT 00Z-02Z...THEN WEAKEN
THEREAFTER. STRONG WINDS AND HAIL ARE POSSIBLE WITH THESE STORMS.
SECOND AREA OF CONCERN IS REGION OF IFR OVER COASTAL RI AND
SOUTHEAST MA. THIS AREA WILL MOVE ONSHORE IMPACTING MUCH OF RI AND
SOUTHEAST MA THROUGH MIDNIGHT OR SO THEN IMPROVE THEREAFTER WITH
THE FRONTAL PASSAGE/WIND SHIFT. FORECAST CONFIDENCE HIGH BUT LOWER
ON AREAL EXTENT OF TSTMS AND IFR.

THU/THU NIGHT...HIGH CONFIDENCE FOR VFR.

KBOS TAF...
MARGINAL VFR/MVFR WITH ANY IFR CONDITIONS REMAINING SOUTH OF THE
TERMINAL. WIND SHIFT OVERNIGHT WITH THE FRONTAL PASSAGE. VFR THU
AND THU NIGHT. FORECAST CONFIDENCE MODERATE TO HIGH.

KBDL TAF...
VFR TO START AND THEN MVFR CIGS IN CLOUD DEBRIS FROM UPSTREAM
TSTMS. MOST IF NOT ALL TSTMS SHOULD REMAIN NORTH OF THE TERMINAL.
THUS JUST A LOW RISK OF A TSTM TIL 01Z. LOW PROBABILITY OF MVFR
VSBYS IN FOG UNTIL FRONTAL PASSAGE/WIND SHIFT 03Z-06Z.

OUTLOOK...

FRI THROUGH MON...HIGH CONFIDENCE FOR VFR AND DRY WEATHER. MON...LOW
CONFIDENCE. VFR TO START BUT POSSIBLY LOWERING TO MVFR IN SHOWERS.

&&

.MARINE...
MODERATE TO HIGH CONFIDENCE. MODEST S/SWLY WINDS GUSTING TO 25 KTS
WILL CONTINUE SWELL AND HIGH SEAS OVER THE OUTER WATERS...WITH 6-8
FT S AND E OF RI OUT TO CAPE COD AND THE ISLANDS. COLD FRNT SHOULD
BE ACROSS THE WATERS DURING THE EARLY MORNING HRS FOLLOWED BY WEAKER
W/NWLY FLOW. MAY BE SOME GUSTS AROUND 15 KTS...BUT NOT CONSIDERING
ANYTHING GREATER. SHOWERS...AND FOG WILL BE PSBL DOWN TO A HALF TO
QUARTER MILE...FOR THE S/SE WATERS OVRNGT AND PRIOR TO THE PASSAGE
OF THE COLD FRNT. SEAS TO DIMINISH BY LATE THURS ALLOWING SMALL
CRAFT ADV TO DROP.

OUTLOOK...FRIDAY THROUGH MONDAY

PLEASANT BOATING WEATHER FRI THROUGH SUN WITH HIGH PRES OVER
SOUTHERN NEW ENGLAND. ONLY WRINKLE COULD BE SOME MODEST SE SWELLS ON
THE OCEAN WATERS FROM LOW PRES SOUTHEAST OF NEW ENGLAND SAT AND SUN.
FORECAST CONFIDENCE DECREASES NEXT WEEK AS THE MAGNITUDE AND TRACK
OF THIS LOW BECOMES UNCERTAIN.
