Severe Thunderstorm Warning 157, NWS Boston/Norton, MA

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
133 PM EDT SUN JUL 20 2008

.SYNOPSIS...
A VERY WARM HUMID AND UNSTABLE PATTERN CONTINUES INTO EARLY NEXT
WEEK. A FRONTAL BOUNDARY OSCILLATING ACROSS NEW ENGLAND WILL YIELD
NEARLY DAILY ROUNDS OF SCATTERED SHOWERS AND THUNDERSTORMS INTO MID
WEEK...GENERALLY STRONGEST AND MOST WIDESPREAD DURING THE AFTERNOON
AND EVENING. A TREND TOWARD SEASONABLE TEMPERATURES AND LOWER
HUMIDITY IS EXPECTED THE MIDDLE AND END OF THE WORK WEEK. TROPICAL
STORM CRISTOBAL WILL LIKELY PASS SE OF NANTUCKET MON NIGHT...AND
COULD CONTRIBUTE TO HIGH SWELLS AND SURF ACROSS PORTIONS OF THE NEW
ENGLAND S AND SE COAST.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
WE ARE WATCHING FOR THE POTENTIAL OF CONVECTIVE DEVELOPMENT OVER THE
NEXT FEW HOURS ALONG A DIFFERENTIAL HEATING BOUNDARY.  THIS EXISTS
FROM OUR CONNECTICUT ZONES...NORTHEASTWARD INTO CENTRAL MA.  SPC
ANALYSIS SHOWS OVER 1000 J/KG OF MLCAPE IN THIS REGION AS SURFACE
TEMPERATURES HAVE REACHED INTO THE LOW 90S ACROSS PORTIONS OF THIS
REGION.  WILL HAVE TO WATCH THIS AREA FOR THE POTENTIAL OF A FEW
SEVERE THUNDERSTORMS DEVELOPING ACROSS THIS AREA OVER THE NEXT FEW
HOURS.

ALSO...PLENTY OF CLOUDS REMAINED NORTH OF THE MA PIKE.
HOWEVER...THERE WERE SOME BREAKS IN CLOUD COVER.  WE WILL HAVE TO
WATCH THIS AREA...ESPECIALLY FROM FAR NORTHERN MA INTO SOUTHERN NH
LATER THIS AFTERNOON/EVENING FOR THE POTENTIAL OF A FEW SEVERE
THUNDERSTORMS.  THE APPROXIMATE TIME FRAME IN THIS REGION LOOKS TO
BE BETWEEN 4 AND 10 PM.  THE MAIN THREAT CONTINUES TO BE THE
POTENTIAL FOR DAMAGING STRAIGHT LINE WIND GUSTS BUT AN ISOLATED
REPORT OR TWO OF LARGE HAIL IS ALSO POSSIBLE.

AS FOR PRECIPITATION CHANCES...WILL RUN WITH LIKELY POPS ACROSS THE
INTERIOR THIS AFTERNOON/EARLY EVENING BASED ON MODEL QPF AND OMEGA
FIELDS.  WILL TAPER JUST TO SLIGHT CHANCES ACROSS FAR SOUTHEAST
MA/CAPE/ISLANDS AS THE BETTER DYNAMICS WILL PASS TO THE NORTHWEST OF
THE REGION.

HIGH TEMPERATURES WILL STILL BE VERY WARM BUT MORE CLOUDS WILL KEEP
THEM LOWER THAN THE PAST FEW DAYS NORTH OF THE MA PIKE.  HIGHS SHOULD BE
IN THE MID TO UPPER 80S NORTH OF THE MA PIKE...WITH LOWER 90S SOUTH
OF THE MA PIKE AND AWAY FROM THE COAST.  IT WILL ALSO BE NOTICEABLE
MORE HUMID.

SURF ZONE: UPGRADED TO MODERATE RISK OF RIP CURRENTS ALONG SOUTH
FACING BEACHES OF THE SOUTH COAST/ISLANDS BASED ON LATEST GUIDANCE
AND REPORTS.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM MONDAY/...
THE 12Z NAM/GFS/CANADIAN ARE ALL IN AGREEMENT AT THE POTENTIAL FOR
HEAVY SHOWERS AND EMBEDDED THUNDERSTORMS ACROSS OUR INTERIOR ZONES
TONIGHT.  THIS WOULD BE SOUTHERN NH AND WESTERN MA.  PWATS ARE
EXPECTED TO BE BETWEEN 2 AND 2.25 INCHES ALONG WITH GOOD JET
DYNAMICS AND ELEVATED INSTABILITY.  ALL THESE MODELS SHOW 1 TO 3
INCHES OF RAINFALL ACROSS THIS REGION TONIGHT.  THEREFORE...WE WILL
BE CONSIDERING A FLASH FLOOD WATCH FOR THE POTENTIAL OF SOME URBAN
AND STREET FLOODING WITH THE AFTERNOON PACKAGE.  OUR CONFIDENCE ONLY
HAS TO BE AT 50 PERCENT FOR A WATCH AND WE WILL BE ASSESSING THIS
POTENTIAL OVER THE NEXT FEW HOURS.  WE WILL HAVE MORE INFORMATION
LATER THIS AFTERNOON.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
GOOD MODEL AGREEMENT ON A LONG WAVE TROF SETTING UP ACROSS THE GREAT
LAKES AND THE NORTHEAST NEXT WEEK. HOWEVER MODELS DIFFER ON THE
EVOLUTION OF THE LONG WAVE TROF...SPECIFICALLY THE TIMING OF IT
DEPARTING NEW ENGLAND MID TO LATE WEEK. THE 00Z GFS APPEARED TO BE
IN THE MIDDLE OF THE PACK REGARDING THESE DETAILS...ALONG WITH
SUPPORT FROM THE 00Z GEFS AND THE 00Z HI RESOLUTION ECMWF.
THEREFORE THIS PORTION OF THE FORECAST WAS WEIGHTED HEAVILY TOWARD
THE 00Z GFS AND ITS MOS OUTPUT.

THIS PATTERN FAVORS MULTIPLE DAYS OF CONVECTION ALONG WITH A TREND
TOWARD SEASONABLE TEMPERATURES AND LOWER HUMIDITY MID TO LATE WEEK.

MONDAY AND MONDAY NIGHT...

WIDESPREAD SHOWERS LIKELY GIVEN DEEP LAYER CYCLONIC FLOW ACROSS THE
NORTHEAST COMBINED WITH FAIRLY ROBUST BAROCLINIC/THERMAL GRADIENT
TROF-FRONTAL BOUNDARY SWEEPING ACROSS THE REGION. IN ADDITION...DEEP
LAYER MOISTURE IN PLACE WITH PWATS AT OR ABOVE 2.0 INCHES COMBINED
WITH DEW PTS IN THE LOW TO MID 70S  THUS...SHOWERS WILL LIKELY
CONTAIN HEAVY DOWNPOURS. VERY WARM AND HUMID CONDITIONS /ALMOST
TROPICAL-LIKE/ EXPECTED.

AS FOR TS CRISTOBAL...ALL OF THE 00Z GUIDANCE TRACKS THIS TROPICAL
CYCLONE SOUTHEAST OF THE 40N/70W BENCHMARK MON NIGHT-TUE. THIS IS
CONSISTENT WITH THE LATEST TPC LATEST FORECAST. THIS SEEMS
REASONABLE GIVEN THE MID LEVEL FLOW DOESN/T BACK SUFFICIENTLY TO THE
S-SW TO STEER CRISTOBAL MORE NORTHERLY AND CLOSER TO NEW ENGLAND. IN
ADDITION...IT IS EXPECTED TO REMAIN A MINIMAL TROPICAL STORM.
THEREFORE...AT THE MOMENT THE MOST LIKELY SCENARIO IS FOR CRISTOBAL
TO REMAIN OFFSHORE WITH LITTLE IF ANY DIRECT IMPACT TO SOUTHERN NEW
ENGLAND. THE MAIN CONCERN WITH CRISTOBAL WILL BE ITS WAVE FIELD
WHICH WILL LIKELY RESULT IN INCREASED SURF ALONG THE RI AND
SOUTHEAST MA BEACHES THIS UPCOMING WEEK. THIS WILL YIELD AN
INCREASED RISK OF STRONG RIP CURRENTS.

TUESDAY...
THERE ARE INDICATIONS THAT TUE MAY TURN OUT TO BE A MAINLY DRY DAY
AS LEAD SHORT WAVE TROF AND CRISTOBAL MOVE EAST OF THE AREA...
FOLLOWED BY SOME SHORT WAVE RIDGING AHEAD OF THE NEXT TROF TO IMPACT
THE REGION MID WEEK. THEREFORE ANY SHOWER/TSTM ACTIVITY SHOULD BE
ISOLATED IN COVERAGE AT MOST.

WEDNESDAY THROUGH SATURDAY...

NEXT BUNDLE OF JET ENERGY APPROACHES THE REGION WED AND WILL RESULT
IN AN INCREASED RISK OF SHOWERS AND THUNDERSTORMS. AS MENTIONED
ABOVE MODELS DIFFER ON THE TIMING OF MID LEVEL TROF EXITING THE
REGION. HOWEVER...THE BULK OF THE GUIDANCE SUGGEST A DRYING TREND
LATER THU INTO FRI...AS MID LEVEL TROF MOVES OFFSHORE. THIS WILL
ALSO USHER IN AN AIRMASS ACROSS THE REGION THAT IS NOT AS HOT AND
LESS HUMID.

&&

.AVIATION /13Z SUNDAY THROUGH THURSDAY/...

TODAY AND TONIGHT...
MARGINAL MVFR/VFR CONDITIONS ACROSS MOST OF THE REGION BY MID
MORNING IN HAZE.  THE EXCEPTION WAS THE CAPE AND ISLANDS WHERE IFR
CONDITIONS IN LOW CLOUDS WERE OBSERVED.  THESE MAY BREAK UP A BIT
FOR A TIME LATE THIS MORNING/EARLY AFTERNOON BUT SHOULD REFORM AGAIN
TOWARD EVENING.

ACROSS THE REST OF THE REGION...MARGINAL MVFR/VFR CONDITIONS IN HAZE
SHOULD CONTINUE INTO THE AFTERNOON.  SCATTERED STRONG THUNDERSTORMS
WITH THE POTENTIAL FOR 40 KNOT WIND GUSTS ARE EXPECTED MAINLY NORTH
OF THE MA TURNPIKE AFTER 18Z OR 19Z THIS AFTERNOON INTO THE
EVENING.

OUTLOOK...MONDAY THROUGH THURSDAY...

MAINLY VFR...WITH CONDITIONS LOWERING TO MVFR IN SCATTERED SHOWERS
AND THUNDERSTORMS EACH DAY. MVFR WILL BE MOST COMMON MON WITH VFR
PREVAILING TUE.

&&

.MARINE...

TODAY AND TONIGHT...
SCA SEAS CONTINUE THIS AFTERNOON FOR PORTIONS OF OUR SOUTHERN
WATERS.  THIS IS MAINLY FOR MARGINAL 5 FOOT SEAS...BUT SHOULD SEE
SOUTHWEST WIND GUSTS IN THE LOW 20 KNOTS DEVELOP IN THIS REGION
DURING THE AFTERNOON WITH MIXING.  A FEW STRONG THUNDERSTORMS WITH
GUSTY WINDS MAY IMPACT THE WATERS LATE THIS AFTERNOON/EVENING BUT
THE BULK OF THIS ACTIVITY SHOULD BE ACROSS THE WATERS NORTH OF
BOSTON HARBOR.

WE WILL LIKELY NEED TO EXTEND SCA FOR LEFT OVER SWELL ACROSS OUR
SOUTHERN OUTER-WATERS FOR TONIGHT.

OUTLOOK...MONDAY THROUGH THURSDAY...

MONDAY/MONDAY NIGHT...S-SW WINDS 15-20 KT ALONG WITH BUILDING SEAS.
SCATTERED TSTMS WITH COLD FRONT MOVING ACROSS THE WATERS.

TUESDAY...FRONT MOVES OFFSHORE WITH IMPROVING WEATHER. HOWEVER OCEAN
WATERS REMAIN ROUGH AS A COMBINATION OF LEFTOVER S WIND WAVES FROM
MON COMBINE WITH S SWELLS FROM CRISTOBAL.

WED AND THU...ANOTHER COLD FRONT ENTERS NEW ENGLAND YIELDING
SCATTERED SHOWERS AND THUNDERSTORMS. MODEST S SWELLS WILL PERSIST
ACROSS THE SOUTH OCEAN WATERS.
