AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
739 PM EDT SUN AUG 31 2014
.SYNOPSIS...
A WARM HUMID FLOW WILL CONTINUE ACROSS NEW ENGLAND THROUGH
TUESDAY WITH SCATTERED SHOWERS AND THUNDERSTORMS FROM TIME TO
TIME. A COLD FRONT WILL MOVE THROUGH TUESDAY NIGHT THEN WARM BUT
LESS HUMID WEATHER WILL FOLLOW FOR WEDNESDAY THROUGH FRIDAY.
ANOTHER COLD FRONT MAY BRING A CHANCE OF SHOWERS AND THUNDERSTORMS
NEXT SATURDAY.
&&
.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
730 PM UPDATE...
MOST UNSTABLE CAPE VALUES CONTINUE TO PLUMMET THIS EVENING...
HAVING DIMINISHED 400-600 J/KG WITHIN THE PAST 3 HOURS. WITH
VALUES OF 500-1000 J/KG STILL...CANNOT RULE OUT THE POSSIBILITY OF
ISOLATED THUNDERSTORMS FOR THE NEXT FEW HOURS. DESPITE THE
RELATIVELY LOW INSTABILITY...THERE IS DECENT EFFECTIVE BULK SHEAR
OF 30-40 KT TO MAXIMIZE IT. WE ARE NOT EXPECTING WIDESPREAD
SEVERE WEATHER THIS EVENING. RATHER THE MAIN THREATS WILL BE
FREQUENT LIGHTNING AND LOCALLY HEAVY RAINFALL. THOSE WITH PLANS
OUTDOORS THIS EVENING SHOULD GO INSIDE IMMEDIATELY IF
THUNDERSTORMS APPROACH YOUR PARTICULAR REGION. REMEMBER...IF YOU
CAN HEAR THUNDER...YOU ARE IN THE POTENTIAL LIGHTNING STRIKE ZONE.
OTHERWISE...ONLY MINOR TWEAKS NEEDED TO THE FORECAST THIS
EVENING. 31/20Z HRRR APPEARED TO HAVE A GOOD HANDLE ON THE TIMING
FOR CONVECTION...SO LEANED HEAVILY UPON IT FOR NEAR TERM RAINFALL
CHANCES.
PREVIOUS DISCUSSION...
CONVECTION FIRING ACROSS EASTERN PA AND NJ AND SE NY IN AXIS OF
SBCAPES 1500-2000 J/KG. CLOSER TO HOME...SBCAPES 500-1000 J/KG BUT
THERE ARE BREAKS DEVELOPING IN THE CLOUDS ACROSS SNE SO FURTHER
DESTABILIZATION IS LIKELY. HI-RES GUIDANCE CONTINUES TO POINT TO A
LATE SHOW WITH CONVECTION 21-00Z AS MID LEVEL SHORTWAVE MOVES IN
FROM THE WEST. PWATS ALREADY NEAR 2" AND EXPECTED TO PEAK AROUND
2.25" TOWARD 00Z SO HEAVY RAINFALL AND LOCALIZED FLASH FLOODING OF
URBAN AND POOR DRAINAGE AREAS IS THE PRIMARY THREAT. 0-6KM SHEAR
APPROACHING 40 KT IN THE WEST SO POTENTIAL EXISTS FOR A FEW STRONG
TO PERHAPS SEVERE TSTMS WITH DAMAGING WIND GUSTS ALSO A CONCERN IF
FURTHER DESTABILIZATION OCCURS.
MAIN FOCUS FOR CONVECTION WILL INITIALLY BE IN THE INTERIOR...BUT
EXPECT AT LEAST A FEW SHOWERS/TSTMS IN A WEAKENED STATE TO MAKE
IT TO THE COASTAL PLAIN LATER THIS EVENING AS SHORTWAVE MOVES
THROUGH. WHILE INSTABILITY WANES TONIGHT...THERE IS STILL
SOME SBCAPE AND HIGH KI VALUES TO SUPPORT CONVECTION. THE COLUMN
WILL WILL BEGIN TO DRY FROM THE N LATE TONIGHT ACROSS N ZONES.
AREAS OF STRATUS AND PATCHY FOG EXPECTED TO DEVELOP OVERNIGHT. IT
WILL BE A WARM AND HUMID NIGHT WITH MINS 65 TO AROUND 70 DEGREES.
&&
.SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/...
MONDAY...
WARM AND HUMID AIRMASS CONTINUES ACROSS THE REGION WITH WEAK SFC
BOUNDARY/FRONT DRAPED ACROSS FAR N NEW ENG. PWATS DECREASE BELOW
1.5" ACROSS THE N BUT TROPICAL PLUME WITH PWATS NEAR 2" WILL
PERSIST IN THE SOUTH. AIRMASS DESTABILIZES AGAIN WITH SBCAPES
1000-1500 J/KG. SCT SHOWERS/TSTMS EXPECTED TO
REDEVELOP...ESPECIALLY ALONG AND SOUTH OF THE MASS PIKE WHERE
DEEPER MOISTURE IS PRESENT IN THE RIGHT ENTRANCE REGION OF THE
UPPER JET. 0-6KM SHEAR IS CONSIDERABLY WEAKER SO SEVERE WX NOT
ANTICIPATED. HEAVY RAINFALL IS THE MAIN THREAT IN HIGH PWAT
AIRMASS. TEMPS WILL REACH LOW TO MID 80S AGAIN...COOLER S COAST.
DEWPOINTS 70+ SO VERY HUMID.
MONDAY NIGHT...
COLUMN MOISTURE GRADUALLY DECREASES THROUGH THE NIGHT. SOME
LINGERING CONVECTION POSSIBLE IN THE EVENING ALONG THE S
COAST...OTHERWISE MAINLY DRY WEATHER. AREAS OF STRATUS AND FOG
WILL LIKELY REDEVELOP OVERNIGHT. ANOTHER HUMID NIGHT.
&&
.LONG TERM /TUESDAY THROUGH SUNDAY/...
OVERVIEW AND MODEL PREFERENCES...
BROAD RIDGING REMAINS THE DOMINATE FEATURE ACROSS THE EASTERN USA
THROUGH MOST OF THIS FORECAST PERIOD. THIS IS MORE TYPICAL FOR THE
MIDDLE OF SUMMER RATHER THAN EARLY SEPTEMBER. EARLY IN THIS
PERIOD...THERE WILL BE A COUPLE OF FAST MOVING SYSTEMS IN THE BROAD
NORTHERN STREAM THAT WILL AFFECT OUR REGION. THIS STRONG RIDGE
FINALLY BECOMES ESTABLISHED AROUND MID WEEK ACROSS THE SOUTHERN
USA...WITH WARM BUT DRY CONDITIONS THROUGH THE END OF THIS WEEK.
SOME QUESTIONS AS TO WHEN THE RIDGING MAY BREAK DOWN...AS MODEL
SOLUTIONS LATE IN THE RUN TRY TO BREAK DOWN THE RIDGE WHILE BRINGING
A MID-LEVEL CUTOFF LOW ACROSS NORTH CENTRAL CANADA INTO NORTHERN
QUEBEC.
OVERALL...HAVE FAIRLY GOOD CONFIDENCE WITH MOST OF THIS FORECAST...
THOUGH SOME QUESTIONS WITH POSSIBLE CHANGES IN THE STEERING PATTERN
OVER THE NORTHERN TIER LATE THIS WEEK. HAVE LEANED TOWARD A BLEND OF
AVAILABLE GUIDANCE INTO FRIDAY...THEN PUSHED TOWARD A BLEND OF THE
ECENS AND GEFS MEANS WHICH SHOWED A SLOWER BREAKDOWN OF THE RIDGING
ACROSS THE REGION...WITH LOWER CONFIDENCE IN THE DETAILS OF
THIS FORECAST FOR THIS WEEKEND.
DAILIES...
TUESDAY...
ANOTHER FRONTAL SYSTEM STEADILY WORKS ITS WAY ACROSS OUT OF NY
STATE...THOUGH SOME TIMING ISSUES IN PLACE AMONGST THE OPERATIONAL
MODEL SUITE. KEPT CHANCE POPS ACROSS SOUTHWEST NH/WESTERN MA AROUND
MIDDAY. THEN PUSHED THIS FRONT....AND THE CORRESPONDING INCREASED
RAINFALL CHANCES...EAST THROUGH THE EVENING AND OVERNIGHT HOURS.
THIS TIMING MAY STILL BE TOO FAST.
WEDNESDAY...EXPECTING DRIER AIR TO SLOWLY ARRIVE DURING THE DAY ON
LIGHT WEST WINDS. HIGH PRESSURE WILL BUILD OUT OF THE APPALACHIANS.
TEMPERATURES WILL REMAIN WARM FOR THIS TIME OF YEAR...WITH A GENERAL
WEST WIND FLOW THROUGHOUT THE LAYER. COULD SEE SOME SHOWERS LINGER
ACROSS CAPE COD AND THE ISLANDS DURING THE EARLY MORNING HOURS.
THURSDAY AND FRIDAY...EXPECTING DRY AND MILD CONDITIONS CONTINUING
WITH DEWPOINTS FALLING INTO THE 50S...THOUGH AROUND 60 ALONG THE
IMMEDIATE COAST. CENTER OF HIGH PRESSURE SHIFTS OFFSHORE...RESULTING
AND LIGHT SOUTHWEST WINDS. THIS SHOULD MEAN SLIGHT ABOVE NORMAL
TEMPERATURES AWAY FROM THE IMMEDIATE COASTS.
SATURDAY AND SUNDAY...LOTS OF QUESTIONS DURING THIS TIMEFRAME...
MAINLY DUE TO TIMING ISSUES OF A COLD FRONT. KEPT MENTION OF CHANCE
POPS AS A COLD FRONT TRIES TO CROSS SOUTHERN NEW ENGLAND THIS
WEEKEND. LOW CONFIDENCE WITH THIS FEATURE. HIGH PRESSURE SHOULD
EVENTUALLY RETURN LATER SUNDAY.
&&
.AVIATION /00Z MONDAY THROUGH FRIDAY/...
FORECASTER CONFIDENCE LEVELS...
LOW...LESS THAN 30 PERCENT.
MODERATE...30 TO 60 PERCENT.
HIGH...GREATER THAN 60 PERCENT.
SHORT TERM /THROUGH MONDAY NIGHT/...HIGH CONFIDENCE IN TRENDS BUT
LOWER CONFIDENCE IN PRECISE DETAILS AND TIMING.
TONIGHT...CONVECTION MAY LINGER TONIGHT AND MOVE ACROSS THE
COASTAL PLAIN BEFORE DIMINISHING. AREAS OF STRATUS AND PATCHY FOG
EXPECTED TO DEVELOP AND EXPAND ACROSS THIS REGION...BUT HIGHEST
PROBABILITY NEAR THE S COAST. EXACT TIMING UNCERTAIN FARTHER
INLAND...BUT SEVERAL SITES ALONG THE IMMEDIATE SOUTH COAST ALREADY
SOCKED IN.
MONDAY...MVFR/IFR CIGS/VSBYS MAY LINGER MOST OF THE DAY ALONG THE
SOUTH COAST...BUT IMPROVING TO VFR IN THE INTERIOR AND ESPECIALLY
FAR N AREAS AS DRIER AIR MOVES IN FROM THE N. SCT SHOWERS/TSTMS
EXPECTED TO DEVELOP WITH BRIEF MVFR/IFR POSSIBLE IN ANY TSTMS.
MONDAY NIGHT...AREAS OF IFR STRATUS AND FOG EXPECTED TO REDEVELOP
BUT UNCERTAINTY ON AREAL EXTENT. A FEW SHOWERS/TSTM MAY LINGER
INTO THE EVENING ALONG THE SOUTH COAST.
KBOS TERMINAL...HIGH CONFIDENCE IN TAF REGARDING TRENDS BUT LOWER
CONFIDENCE ON PRECISE DETAILS AND TIMING.
KBDL TERMINAL...HIGH CONFIDENCE IN TAF REGARDING TRENDS BUT LOWER
CONFIDENCE ON PRECISE DETAILS AND TIMING.
OUTLOOK...TUESDAY THROUGH FRIDAY...
TUESDAY...MODERATE CONFIDENCE.
MVFR-IFR VSBYS THROUGH AROUND 14Z IN PATCHY FOG...THEN BRIEF
PERIOD OF VFR. MAY SEE PERIODS OF MVFR IN SCT SHOWERS/TSTMS
ESPECIALLY INLAND DURING THE AFTERNOON/EVENING. PRECIP SHOULD
TAPER OFF AFTER MIDNIGHT. PATCHY FOG RETURNS AFTER 05Z-06Z WITH
MVFR-IFR VSBYS IN NORMALLY PRONE INLAND LOCATIONS.
WEDNESDAY THROUGH FRIDAY...MODERATE CONFIDENCE. EXPECTING MAINLY VFR
CONDITIONS AS HIGH PRESSURE BUILDS IN. LOCAL MVFR-IFR VSBYS AND CIGS
IN LATE NIGHT PATCHY FOG AND STRATUS. MAIN AREAS OF CONCERN WILL BE
THE TYPICALLY PRONE LOCATIONS ACROSS THE FAR INTERIOR /SOUTHWEST NH
AND NORTH CENTRAL AND WESTERN MA/.

INTO THE EVENING ALONG THE SOUTH COASTAL NEARSHORE WATERS SO SCA
WILL CONTINUE. OVER THE OUTER WATERS...EXPECT WINDS TO REMAIN
BELOW SCA BUT BUILDING SEAS TO NEAR 5 FT SO SCA HERE AS WELL.
THE LOW LEVEL JET MOVES OFF THE COAST OVERNIGHT WITH DECREASING
WINDS. WINDS AND SEAS WILL BE BELOW SCA THRESHOLDS MONDAY INTO

The Boston radar (KBOX), 84 km away, was scanning. The volume nearest the first event began at 00:00 UTC.
2 flash flood, 1 tornado, 1 flood. Local standard time, as filed.
Gilbert Street was flooded and impassable. Flood waters extended into a home.
A tornado touchdown occurred near the intersection of Perry Avenue and Fairfax Road. A narrow well-defined damage path extended past Saint Vincent Hospital to Gordon Street. The most significant damage was to trees, some of which were uprooted or snapped. Some trees landed on cars causing significant damage to the cars. A couple of trees landed on houses, but there was little structural damage to the houses. A few windows were broken by tree branches.
Numerous streets in Worcester were flooded and impassable. Manhole covers popped on Park Avenue. A car was stuck in flood waters on southbound Route 146 at exit 12. Cars were flooded in a parking lot on Glennie Street near the W. B. Mason store.
Three lanes of Route 128 in Burlington were closed due to flooding. There was also 6 inches of flooding across the all lanes of Route 128 near North Street in Reading.
