AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
700 PM EDT TUE MAY 19 2015
.SYNOPSIS...
A FEW STRONG THUNDERSTORMS ARE POSSIBLE THIS EVENING ACROSS WESTERN
MASSACHUSETTS AND NORTHERN CONNECTICUT IN ASSOCIATION WITH A COLD
FRONT. OTHERWISE...DRY AND NICE WEATHER IS ON TAP FOR WEDNESDAY WITH
NEAR OR JUST BELOW NORMAL TEMPERATURES. DRY WEATHER RETURNS FOR
THURSDAY WITH A FEW SHOWERS POSSIBLE ON FRIDAY AHEAD OF A COLD
FRONT. COOLER BUT DRY WEATHER RETURNS FOR THE WEEKEND.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
***A FEW STRONG TO PERHAPS A MARGINALLY SEVERE THUNDERSTORM OR TWO
POSSIBLE BETWEEN 7 AND 10 PM ACROSS WESTERN MA/NORTHERN CT***
7PM UPDATE...
LATEST OBS SUGGEST THAT THE COLD FRONT IS JUST NOW MAKING IT INTO
THE HUDSON RIVER VALLEY AND CATSKILLS...WITH A BAND OF WEAK
CONVECTION MOVING ALONG WITH IT. AHEAD OF THIS FRONT...SOME
ISOLATED SVR STORMS HAVE DEVELOPED...BUT CONTINUE TO DIMINISH AS
THEY APPROACH SRN NEW ENGLAND...WHICH DESTABILIZED LATE IN THE
DAY. BEST INSTABILITY NOW RESIDES MAINLY IN SRN NW AND SW CT
THROUGH EXTREME SW MA. SO WILL NEED TO CONTINUE TO WATCH THIS AREA
AS THE FRONT MOVES THROUGH...ESPECIALLY THANKS TO NEARLY 40 KT OF
0-6KM SHEAR TO HELP IT ALONG. HOWEVER...AS THE SUN CONTINUES TO
SET...SUSPECT WE WILL SEE A GRADUAL END TO THE CONVECTION...WHICH
SHOULD BE DONE COMPLETELY BY ABOUT 03-04Z. HAVE TIMED AND ADJUSTED
POPS TOWARD THIS THINKING...HIGHLIGHTING MAINLY JUST THE SW
PORTIONS OF THE FORECAST AREA THROUGH 04Z. WILL ALSO CONTINUE
MENTION OF TSRA/GUSTY WINDS/HEAVY RAIN FOR THE TIME BEING.
PREVIOUS DISCUSSION...
JUST SOME LEFT OVER SHOWERS ACROSS THE FAR SOUTHEAST NEW ENGLAND
COAST AT LATE AFTERNOON. THIS ACTIVITY SHOULD EXIT THE REGION OVER
THE NEXT FEW HOURS. MEANWHILE...PARTIAL SUNSHINE HAS DEVELOPED
ACROSS OUR WESTERN ZONES. THIS WILL LIKELY ALLOW FOR TEMPS TO SURGE
INTO THE 70S TOWARD EVENING. HOWEVER...LOW CLOUDS AND PATCHY FOG
WILL REMAIN ENTRENCHED ACROSS THE SOUTHEAST NEW ENGLAND COAST
KEEPING TEMPS IN THE UPPER 50S AND 60S.
THE MAIN QUESTION BECOMES HOW MUCH INSTABILITY DEVELOPS THIS EVENING
ACROSS WESTERN MA/NORTHERN CT AHEAD OF THE PRE-FRONTAL TROUGH/COLD
FRONT. BASED ON THE LATEST DATA WE ARE THINKING THAT 500 TO 1000
J/KG OF CAPE DEVELOP TOWARD EVENING. AT THE SAME TIME...0 TO 6 KM
SHEAR VALUES ARE INCREASING TO BETWEEN 35 AND 45 KNOTS AS A STRONG
SHORTWAVE WORKS INTO THE REGION.
THIS SETUP IN SOUTHERN NEW ENGLAND IS RATHER MARGINAL.
DESPITE...VERY GOOD SHEAR RATHER MARGINAL INSTABILITY WILL BE A
LIMITING FACTOR. IN ADDITION...TIMING LOOKS TO BE BETWEEN 5 AND 10
PM THIS EVENING SO A FEW HOURS AFTER TYPICAL PEAK
HEATING/INSTABILITY.
ALL IN ALL...NOT REALLY MUCH CHANGE FROM THE PREVIOUS FORECAST. A
FEW STRONG THUNDERSTORMS WITH PERHAPS A MARGINALLY SEVERE
THUNDERSTORM OR TWO ARE POSSIBLE BETWEEN 6 AND 10 PM THIS EVENING
ACROSS WESTERN MA/NORTHERN CT. THE MAIN CONCERN IS VERY LOCALIZED
STRONG TO DAMAGING WIND GUSTS WITH HAIL A SECONDARY CONCERN. ACROSS
EASTERN NEW ENGLAND...INSTABILITY WILL BE QUITE LIMITED. SO DESPITE
GOOD FLOW ALOFT THE ACTIVITY WILL WEAKEN AS IT TRIES TO MOVE EAST.
IF ANY ACTIVITY DOES SURVIVE...PROBABLY JUST A FEW SHOWERS ARRIVE
ACROSS EASTERN MA/RI LATE THIS EVENING.
MUCH DRIER AND COOLER AIR WORKS INTO THE REGION BEHIND THE COLD
FRONT AFTER MIDNIGHT. LOW TEMPS BY DAYBREAK WILL BE DOWN INTO THE
UPPER 40S TO THE MIDDLE 50S. LEFT OVER LOW CLOUDS/FOG PATCHES WILL
SCOUR OUT TOWARD DAYBREAK ACROSS THE FAR SOUTHEAST NEW ENGLAND
COAST.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH 6 PM WEDNESDAY/...
WEDNESDAY...
MUCH DRIER AIR CONTINUES WILL WORK INTO SOUTHERN NEW ENGLAND BEHIND
THE COLD FRONT. PARTLY SUNNY SKIES ARE EXPECTED BUT THERE WILL BE
SOME SCATTERED DIURNAL CUMULUS CLOUDS ESPECIALLY ACROSS OUR NORTHERN
ZONES. 850 MB TEMPS DROP TO BETWEEN 0C AND +4C BY 18Z...BUT THERE
WILL BE DEEP MIXING. THEREFORE...EXPECT HIGHS TO REACH WELL INTO
THE 60S...WITH PERHAPS A FEW LOCATIONS TOUCHING 70 ACROSS RHODE
ISLAND/SOUTHEAST MA. IT WILL BE BLUSTERY AS GOOD MIXING WILL RESULT
IN A FEW HOURS OF NORTHWEST WIND GUSTS OF 25 TO 30 MPH DURING THE
AFTERNOON.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
*/ HIGHLIGHTS...
- SEASONABLE AND DRY UNDER HIGH PRESSURE THURSDAY
- SWEEPING COLD FRONT FRIDAY
- RETURN OF DRY AND COOLER CONDITIONS FOR THE WEEKEND
- PERHAPS A RETURN OF WET-WEATHER EARLY NEXT WEEK
OVERVIEW AND MODEL PREFERENCES...
WITH 19.12Z MODEL GUIDANCE CONTINUING TO SHOW REASONABLY GOOD
AGREEMENT THROUGH THE LONG TERM...A BLEND OF OPERATIONAL GUIDANCE
AND PERSISTENCE WILL BE USED AS A BASELINE. THERE ARE A FEW TWEAKS
TO MAKE. THE LONGWAVE TROF THAT SETTLES ACROSS ERN CANADA AND THE
NE CONUS WILL ALLOW FOR A FAIRLY COLD AIRMASS TO ADVECT ACROSS THE
REGION WITH A STRONG VORTEX MOVING THROUGH ON FRI...MANIFESTING AS
A COLD FRONT. MODEL DWPTS ARE LIKELY TOO HIGH HERE. WHICH MEANS
THAT SHOULD THE PRES GRADIENT SLACKEN ENOUGH BOTH FRI AND SAT
NIGHTS...MAY NEED TO MONITOR FOR A PERIOD WHERE FROST IS POSSIBLE.
ALSO...AS NOTED BY PREVIOUS FORECASTER...THIS DRY AIR WOULD ALSO
SUGGEST HIGHER FIRE WEATHER POTENTIAL DEPENDENT ON RAINFALL
TODAY/THIS EVENING.
DETAILS...
WED NIGHT INTO THU NIGHT...
MAINLY DRY WX EXPECTED AS HIGH PRES MOVES ACROSS THE REGION. WILL
LIKELY SEE SOME PERSISTENT CLOUD COVER AT TIMES THOUGH...GIVEN
UPPER LVL CYCLONIC CURVATURE AND MODEST MID LVL MOISTURE. +3C TO
+5C H85 TEMPS SHOULD STILL BE REACHED...IF NOT EVEN SLIGHTLY
HIGHER. THEREFORE...SUSPECT MAX/MIN VALUES NEAR SEASONAL NORMALS.
FRI...
FAIRLY ROBUST ARCTIC INFLUENCED VORTEX WILL BE MOVING THROUGH THE
BASE OF THE LONGWAVE TROF ACROSS THE NE CONUS AND ERN CANADA. THE
SFC REFLECTION IS ITSELF A STRONG COLD FRONT WITH DECENT
BAROCLINIC PACKING EVIDENT. THEREFORE...PLENTY OF POTENTIAL FOR
LIFT WITH THIS FEATURE AS IT MOVES ACROSS THE REGION FRI. THE
LIMITING FACTOR IS MOISTURE AS PREVIOUS LONG TERM FORECASTER
NOTED. PWATS REALLY ONLY TOP OUT AROUND 0.60 INCHES. BY THE
AFTERNOON. STILL FEEL THE SLIGHT CHANCE POPS ADVERTISED ARE
WARRANTED...ESPECIALLY JUST GIVEN HOW HIGH THE LIFT POTENTIAL IS
WITH THE FRONT ITSELF. THERE IS A LITTLE BIT OF LOW LVL
INSTABILITY INVOF THE BL TO WORK WITH AS WELL. THEREFORE...WILL
MAINTAIN PRECIP CHANCES AS THEY STAND FOR THE TIME BEING.
FRI NIGHT INTO SAT...
AS MENTIONED ABOVE THE KEY FOR THIS TIME PERIOD IS THE
POTENTIALLY DRY AND COOL AIRMASS WHICH IS PROGGED TO SETTLE ACROSS
THE REGION. IN FACT 1000-500 THICKNESS VALUES ARE SUB 540DAM FOR
MUCH OF THE REGION. WITH H85 TEMPS DIPPING BELOW 0C FOR SAT.
THEREFORE...WILL NEED TO MONITOR FOR LOW DWPTS AND RH VALUES BY
DAY...AND POTENTIALLY NEAR FREEZING TEMPERATURES FOR COLDER
VALLEYS AT NIGHT. CONFIDENCE IS NOT HIGH ENOUGH TO ALARM ON FROST
POTENTIAL AT THIS POINT GIVEN THERE IS SOME QUESTION IN THE PRES
GRADIENT AND WINDS REMAINING ELEVATED...BUT FEEL IT IS AT LEAST
WORTH MENTIONING/MONITORING.
EARLY NEXT WEEK...
SUBTROPICAL RIDGING WILL ONCE AGAIN BE GAINING STRENGTH THROUGH
THE PERIOD...ALLOWING FOR A WARMING OF THE COLUMN ACROSS THE NE
THROUGH THE PERIOD. ASIDE FROM THE WARMING...INDICATIONS OF A WARM
FRONTAL PASSAGE WITH POTENTIAL FOR PRECIP/CONVECTION INDICATED FOR
TUES. SOMETHING TO KEEP AN EYE ON.

VFR MAINLY W OF A PVD-BOS LINE WILL REMAIN THROUGH THE OVERNIGHT
HOURS. THE ONLY CAVEAT WILL BE THE POSSIBILITY OF A BRIEF
TSRA/SHRA ESPECIALLY AT TERMINALS IN CT AND EXTREME SW MA. THIS
RISK ENDS BY ABOUT 04Z.
TO THE E OF THIS LINE. A PERIOD OF IFR/MVFR CONDITIONS PERSISTS IN
LOW CLOUDS AND FOG. UNTIL A COLD FRONT MOVES THROUGH MAINLY
BETWEEN 04Z-07Z. AFTER WINDS SHIFT TO THE W EXPECT IMPROVEMENT TO

TONIGHT...MODERATE TO HIGH CONFIDENCE. MAIN CONCERN WILL BE FOR
AREAS OF FOG ACROSS OUR SOUTHERN WATERS FOR THE FIRST PART OF THE
NIGHT...SOME OF WHICH MAY BE LOCALLY DENSE. OTHERWISE...SOUTHWEST
WINDS AT 10 TO 15 KNOTS WILL SHIFT TO THE NORTHWEST AFTER MIDNIGHT
BEHIND A STRONG COLD FRONT. SOME GUSTS INTO THE LOWER 20 KNOTS ARE
EXPECTED WITH PRESSURE RISES BEHIND THE FRONT.
WEDNESDAY...HIGH CONFIDENCE. A FEW HOURS OF NORTHWEST WIND GUSTS OF
25 KNOTS EXPECTED NEAR SHORE WITH DEEP MIXING OVER THE LAND. HAVE
HOISTED SCA HEADLINES MAINLY FOR OUR NEAR SHORE WATERS. STRONGEST

THRESHOLDS THROUGH THIS PERIOD. WINDS WILL BE SHIFTING FROM
