Severe Thunderstorm Warning 15, NWS Boston/Norton, MA

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
323 PM EDT SUN JUN 2 2013

.SYNOPSIS...
ONE MORE DAY OF WARM TEMPERATURES WILL GIVE WAY TO SCATTERED
THUNDERSTORMS THIS AFTERNOON AND EVENING. SOME OF THESE STORMS
MAY BE SEVERE ACROSS WESTERN NEW ENGLAND. TONIGHT AND MONDAY...A
SLOW MOVING COLD FRONT WILL DELIVER PERIODS OF POTENTIALLY HEAVY
RAIN UNTIL THE FRONT SLIDES OFFSHORE BY MONDAY NIGHT. DRIER AND
MUCH COOLER WEATHER FOLLOWS BEHIND THE COLD FRONT BEGINNING MON
NIGHT THROUGH MIDWEEK. A COASTAL STORM MAY BRING MORE SHOWERS BY
THE END OF THE WEEK.

&&

.NEAR TERM /UNTIL 8 PM THIS EVENING/...
* SEVERE THUNDERSTORM WATCH REMAINS IN EFFECT UNTIL 8 PM *

2 PM UPDATE...

NOT MUCH CHANGE TO PREVIOUS THINKING. STORMS ARRIVE IN WESTERN
CT/MA AND SOUTHWEST NH BETWEEN 2PM - 5 PM...THEN INTO CENTRAL MA
FROM 5 PM TO 8 PM. THEREAFTER STORMS WILL WEAKEN AND BECOME LESS
ORGANIZED AND AS INSTABILITY WANES WITH SUNSET. IN FACT MUCH OF
THE ACTIVITY MAY DRY UP BEFORE REACHING RI AND EASTERN MA. SEVERE
THREATS CONTINUE TO BE DAMAGING WINDS...ISOLATED LARGE HAIL AND
VERY HEAVY RAINFALL. PROBABILITY IS GREATEST ACROSS WESTERN CT/MA
AND SOUTHWEST NH.

SOME INTERESTING FEATURES ON SATELLITE AT 2 PM. CU FIELD REFUSES
TO DEVELOP EAST OF THE CT RIVER VALLEY. SPC MESO ANALYSIS PAGE
INDICATES THIS IS THE DIVIDING LINE BETWEEN CONVECTIVE INHIBITION
EAST OF THE CT RVR AND SB INSTABILITY TO THE WEST. 12Z MODELS
CAPTURING THIS VERY WELL AND KEEP THETA-E/SB INSTABILITY AXIS
ALONG AND WEST OF CT RVR VLY THROUGH 00Z. THUS THIS IS THE AREA OF
GREATEST RISK FOR SEVERE STORMS.

ALSO STRATUS HAS BEEN HANGING ON TOUGH ACROSS MVY/ACK AND OUTER
CAPE. 12Z CHH SOUNDING INDICATES VERY DRY COLUMN...WHICH IS
PROBABLY CAUSED BY SUBSIDENCE/DRYING THROUGH THE COLUMN.

HIGHS AT 2 PM WERE MAINLY IN THE U80S TO L90S AWAY FROM THE SOUTH
COAST. FOR SOME LOCATIONS THIS WILL BE THE 4TH CONSECUTIVE DAY OF
90+ HEAT! MEANWHILE STRATUS HOLDING MVY/ACK/CQX TO THE MU60S!
GOTTA LOVE NEW ENGLAND WEATHER.

&&

.SHORT TERM /8 PM THIS EVENING THROUGH 6 PM MONDAY/...
TONIGHT...
ANY CONVECTION THAT IS MOVING THROUGH OR INITIATED IN THE REGION
WILL GRADUALLY BECOME ELEVATED THROUGH THE EARLY OVERNIGHT HOURS
AS THE LOSS OF DIURNAL HEATING CUTS OFF SFC BASED INSTABILITY.
GIVEN MARGINAL LAPSE RATES...THIS WILL TEND CONVECTION TOWARD MORE
OF A HEAVY RAIN THREAT RATHER THAN WIND THREAT. ELEVATED PWATS
NEAR 2.0 INCHES...ELEVATED INSTABILITY AND THE POTENTIAL FOR BACK
BUILDING CONVECTION IS POSSIBLE. THEREFORE...WILL NEED TO MONITOR
FOR OVERNIGHT URBAN/POOR DRAINAGE OR EVEN FLASHY SMALL STREAM
FLOODING AS THE CONVECTION WANES INTO THE EARLY MORNING HOURS.

THERE IS ONE CAVEAT HERE...GUIDANCE OF LATE HAS BEEN SHOWING THE
POSSIBILITY OF A BRIEF BREAK IN PRECIP ACTIVITY AS CONVECTION DIES
AND INITIAL SHORTWAVE ENERGY PUSHES ENE...WITH SOME SLIGHT RIDING
NOTED IN MASS FIELDS AHEAD OF A SECOND FRONTAL WAVE ASSOCIATED
WITH THE ACTUAL COLD FRONT. THEREFORE...THERE MAY ACTUALLY BE A
BRIEF BREAK IN PRECIPITATION OVERNIGHT LEADING INTO MON MORNING
UNTIL THE SECONDARY WAVE ARRIVES AND LIFT PROVIDED BY THE ACTUAL
COLD FRONT APPROACHES.

MON...
SECONDARY FRONTAL WAVE APPROACHES AS COLD FRONT CONTINUES TO MAKE
SLOW PROGRESSION ACROSS THE REGION. STILL NOTING SOME ELEVATED
INSTABILITY AND DECENT MOISTURE ASSOCIATED WITH THIS WAVE...SO THE
HEAVY RAIN THREAT CONTINUES...POSSIBLY EFFECTING THE MORNING
COMMUTE. THERE WILL STILL NEED TO MONITOR THE URBAN AND SMALL
STREAM FLOODING THREAT. GIVEN THE FRONT IS NEARLY PARALLEL WITH
STEERING FLOW...IT WILL LIKELY TAKE MOST OF THE DAY FOR PRECIP TO
END ACROSS THE REGION...WITH ONLY SOME CLEARING POSSIBLY BE
EVENING IN THE N AND W.

&&

.LONG TERM /MONDAY NIGHT THROUGH SUNDAY/...
HIGHLIGHTS...

  * COOLER...DRIER WEATHER EXPECTED MON NIGHT THROUGH THU
  * STORM SYSTEM THE END OF THE WEEK MAY BRING WET WEATHER TO SNE.

MODELS ARE IN PRETTY GOOD AGREEMENT THROUGH THE MIDDLE OF THIS WEEK.
TOWARDS THE END OF THE WEEK THERE START TO BE GREATER DISCREPANCIES
BETWEEN THE ECMWF AND GFS AS WELL AS THEIR ENSEMBLES.  WILL START
THE LONG TERM WITH COOLER...DRIER WEATHER AS THE COLD FRONT MOVES
OFFSHORE MONDAY NIGHT AND COOL HIGH PRESSURE BUILDS IN BEHIND.
EARLY THIS WEEK...THE ECMWF AND MEMBERS OF BOTH THE GEFS AND ECENS
START TO DEVELOP A TROPICAL CYCLONE IN THE GULF OF MEXICO.  THE
ECMWF BRINGS THIS CYCLONE THROUGH THE GULF...OVER FLORIDA AND TO THE
GEORGIA COAST BY THURSDAY.  THE ECMWF BRINGS IT NORTH TO THE
CAROLINAS BEFORE SENDING IT EAST OUT TO SEA SOUTH OF SOUTHERN NEW
ENGLAND.  AS ITS FORECAST RIGHT NOW...IMPACT ON SOUTHERN NEW ENGLAND
WOULD BE LIMITED TO HIGH SURF AT THE SHORELINES AND HIGH SEAS ON THE
COASTAL WATERS.  AGAIN...THERE ARE OTHER SOLUTIONS STILL BEING
MODELED BY THE GFS AND OTHER MEMBERS OF THE ENSEMBLES.  THE 02/12Z
GFS HAS ENOUGH SHEAR THAT A CYCLONE WOULD BE UNABLE TO FORM AND LOW
PRESSURE DEVELOPS OVER THE APPALACHIANS AND MOVES NORTHEASTWARD JUST
OFF THE COAST OF SOUTHERN NEW ENGLAND.  THIS PRESENTS A VERY
DIFFERENT SENSIBLE WEATHER SCENARIO OVER SOUTHERN NEW ENGLAND.  THIS
IS DEFINITELY A PATTERN TO KEEP AN EYE ON AS THE MODEL TRENDS EVOLVE.

MONDAY NIGHT...THE COLD FRONT THAT HAS BEEN AFFECTING OUR WEATHER
FOR THE PAST DAY OR SO WILL FINALLY FINISH MOVING ACROSS SOUTHERN
NEW ENGLAND OVERNIGHT.  EXPECT THE COLDEST TEMPERATURES OVERNIGHT
OVER THE NORTHWESTERN ZONES WHERE THE FRONT WILL MOVE THROUGH FIRST.
EXPECT LOWS IN THE 40S IN THE NORTHWESTERN ZONES AND 50S FARTHER
EAST WHERE THE FRONT TAKES ITS TIME MOVING THROUGH.  BEHIND THE
FRONT EXPECT CLEARING SKIES AND CALMER WINDS THAT WILL AID IN THIS
COOLING WHILE MOSTLY CLOUDY TO OVERCAST SKIES IN THE EAST WILL
SLOWLY CLEAR OUT.

TUESDAY THROUGH THURSDAY...COOL HIGH PRESSURE BUILDS INTO SOUTHERN
NEW ENGLAND.  THIS WILL BRING MORE SEASONABLE WEATHER TO THE REGION
WITH HIGHS IN THE UPPER 60S TO LOWER 70S...LOWS IN THE UPPER 40S TO
LOWER 50S...MOSTLY SUNNY/CLEAR SKIES AND LIGHT WINDS.

FRIDAY THROUGH SUNDAY...THIS IS THE PERIOD TO WATCH FOR THE NEXT
POTENTIAL FOR SIGNIFICANT WEATHER.  AS DISCUSSED ABOVE...SOME OF THE
MODELS AND ENSEMBLE MEMBERS INDICATE THE POTENTIAL FOR A TROPICAL
CYCLONE NEARING OUR AREA DURING THIS TIME FRAME.  HOWEVER...THERE IS
MUCH UNCERTAINTY AT THIS POINT...ESPECIALLY CONSIDERING THAT THE
MOST BULLISH MODELS HAVE THE STORM TAKING A TURN TO THE RIGHT OFF
THE NORTH CAROLINA SHORE...WITH LITTLE IMPACT ON SOUTHERN NEW
ENGLAND OUTSIDE THE COASTAL WATERS AND PERHAPS THE BEACHES.  THE
ALTERNATE SOLUTION CURRENTLY IS A NON TROPICAL LOW PRESSURE SYSTEM
DEVELOPING IN THE APPALACHIANS AND MOVING NEAR TO SOUTHERN NEW
ENGLAND AS A COOL COASTAL STORM.  THIS SOLUTION BRINGS SUBSTANTIALLY
COOLER THAN NORMAL TEMPS TO THE REGION ALONG WITH RAIN.  WILL BE
KEEPING A CLOSE EYE ON THE MODEL TRENDS OVER THE COMING WEEK.

&&

.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
FORECASTER CONFIDENCE LEVELS...

LOW...LESS THAN 30 PERCENT.
MODERATE...30 TO 60 PERCENT.
HIGH...GREATER THAN 60 PERCENT.

2 PM UPDATE...

OVERVIEW...MODERATE TO HIGH CONFIDENCE ON TSTM FORECAST BUT LOWER
CONFIDENCE ON TIMING AND AREAL EXTENT OF IFR CONDITIONS TONIGHT
AND MON.

THROUGH 00Z...
TSTMS WILL BE CONFINED TO WESTERN NEW ENGLAND/EASTERN NY BORDER
THROUGH 21Z. AFTER 21Z TSTMS WILL GET VERY CLOSE TO KBDL-KCEF-
KORE-KAFN-KCON AND POINTS WEST. 21Z-00Z STORMS MAY GET CLOSER TO
KORH-KFIT-KASH-KMHT. STRONGEST STORMS WILL BE ALONG AND NORTHWEST
OF BDL-CEF-ORE-AFN-CON. MAIN HAZARDS ARE STRONG WINDS...LARGE HAIL
AND VERY HEAVY RAIN. IFR CIGS WILL SLOWLY ERODE ACROSS CAPE COD
AND THE ISLANDS.

AFTER 00Z...
LINE OF TSTMS ACROSS WESTERN-CENTRAL NEW ENGLAND SLIDE SOUTHEAST
BUT WEAKEN AND LIKELY BECOME A BROKEN LINE. HIGH PROBABILITY OF
IFR CONDITIONS IN FOG/RAIN SHOWERS ACROSS EASTERN CT/RI AND
EASTERN MA AFTER 03Z AND ESPECIALLY AFTER 06Z.

MON...
MAINLY MVFR IN SHOWERS BUT IFR LIKELY ACROSS SOUTHEAST MA. SHOWERS
WITH EMBEDDED TSTMS LIKELY ACROSS CT/RI AND EASTERN MA INCLUDING
KORH-KBOS. MAIN THREATS WILL BE LIGHTNING AND VERY HEAVY RAINFALL.
AREA OF SHOWERS/TSTMS WILL SLOWLY SLIDE SOUTHEAST THROUGH THE DAY
AND MOVING OFFSHORE TOWARD 00Z TUE.

KBOS TERMINAL...HIGH CONFIDENCE IN TAF. VFR CONDITIONS UNTIL
OVERNIGHT TONIGHT WITH ANY TSTMS HOLDING OFF UNTIL 00Z-03Z AT THE
EARLIEST.

KBDL TERMINAL...HIGH CONFIDENCE IN TAF. STRONG STORMS POSSIBLE
21Z-00Z WITH DAMAGING WINDS...LARGE HAIL AND HEAVY RAINFALL.

OUTLOOK...MONDAY NIGHT THROUGH FRIDAY...

MONDAY NIGHT...MODERATE TO HIGH CONFIDENCE. GUSTY SOUTHWEST WINDS
WILL SHIFT TO THE NORTHWEST AS A COLD FRONT MOVES THROUGH SOUTHERN
NEW ENGLAND.  ANY MVFR/IFR CONDITIONS IN LOW CLOUDS/FOG WILL IMPROVE
TO VFR THROUGH THE NIGHT.

TUESDAY AND WEDNESDAY...HIGH CONFIDENCE.  VFR.

THURSDAY AND FRIDAY...LOW CONFIDENCE.  MAINLY VFR.  MVFR/IFR
CONDITIONS POSSIBLE IN SHOWERS/LOW CLOUDS/FOG.

&&

.MARINE...
FORECASTER CONFIDENCE LEVELS...

LOW...LESS THAN 30 PERCENT.
MODERATE...30 TO 60 PERCENT.
HIGH...GREATER THAN 60 PERCENT.

1030 AM UPDATE...
TIMING OF TSTMS...SHOULD HOLD OFF UNTIL AFTER DARK...THEN MOVING
ACROSS THE WATERS LATER THIS EVENING AND OVERNIGHT. FOG AND
REDUCED VSBY ACROSS CAPE COD AND ISLANDS CONTINUES TO BURN OFF AND
SHOULD BE COMPLETELY GONE BY NOON.

MODERATE CONFIDENCE THROUGH THE PERIOD.

HAVE DROPPED THE GALE WATCH IN FAVOR OF A HIGHER END SMALL CRAFT
ADVISORY FOR EASTERN MA WATERS. CAN/T RULE OUT THAT A FEW GUSTS
MAY BREAK 34 KT THIS AFTERNOON...BUT THEY WOULD LIKELY BE
GENERALLY AROUND 30 KT WITH ONLY A FEW GUSTS TO GALE FORCE.
THEREFORE...WAS NOT CONFIDENT ENOUGH FOR A FULL FLEDGED GALE...BUT
WILL BOATERS WILL STILL NEED TO KEEP AN EYE ON WIND GUSTS THROUGH
THE AFTERNOON. OTHERWISE...WILL CONTINUE SMALL CRAFT ADVISORIES
THROUGH THE OVERNIGHT HOURS AND INTO MONDAY FOR THE SOUTHERN
OCEAN WATERS.

WILL ALSO NEED TO MONITOR FOR LATE AFTERNOON/EVENING THUNDERSTORMS
AS THESE WILL HAVE THE ABILITY TO CREATE VERY STRONG WIND
GUSTS...FREQUENTLY LIGHTNING AND SOME HEAVY RAIN.

OUTLOOK...MONDAY NIGHT THROUGH FRIDAY...

WINDS AND SEAS DIMINISH SLOWLY MONDAY NIGHT THROUGH TUESDAY.
SOUTHWESTERLY WINDS WILL SHIFT TO THE NORTHWEST AS A COLD FRONT
CROSSES THE WATERS LATE MONDAY NIGHT INTO TUESDAY MORNING.  WINDS
AND SEAS REMAIN BELOW SMALL CRAFT ADVISORY CRITERIA THROUGH MUCH OF
THE WEEK AS HIGH PRESSURE BUILDS OVER THE WATERS.  WINDS AND SEAS
MAY INCREASE FRIDAY IN RESPONSE TO A LOW PRESSURE SYSTEM NEAR THE
WATERS.

&&

.BOX WATCHES/WARNINGS/ADVISORIES...
CT...NONE.
MA...NONE.
NH...NONE.
RI...NONE.
