AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
933 AM EDT MON JUL 27 2015

.SYNOPSIS...
RISK OF SHOWERS AND THUNDERSTORMS CONTINUES THROUGH TUESDAY.
STORMS MAY PRODUCE HEAVY RAIN AND A FEW MANY BECOME STRONG TO
SEVERE. HOT AND HUMID TUESDAY THROUGH THURSDAY. A COLD FRONT MAY
BRING SCATTERED THUNDERSTORMS LATE THURSDAY AND THURSDAY NIGHT.
WARM AND DRY WEATHER IS EXPECTED FRIDAY INTO NEXT WEEKEND.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

***SCATTERED SHOWERS AND EMBEDDED THUNDERSTORMS WILL DEVELOP
  NORTHWARD MUCH OF SOUTHERN NEW ENGLAND THIS AFTERNOON WITH LOCALLY
  HEAVY RAINFALL/STREET FLOODING THE MAIN CONCERN***

930 AM UPDATE...

NUMEROUS SHOWERS AND EMBEDDED THUNDERSTORMS WITH LOCALLY HEAVY
RAINFALL HAVE BEEN OCCURRING THROUGH MID MORNING ACROSS RHODE ISLAND
AND INTO SOUTH COASTAL MASSACHUSETTS.  ACTIVITY WAS MOVING QUITE
SLOWLY PRODUCING LOCALLY HEAVY RAINFALL AND AT THE VERY LEAST SOME
POOR DRAINAGE STREET FLOODING.  WE ARE GOING TO HAVE TO KEEP A CLOSE
EYE ON THIS REGION TO SEE IF AN AREA OR TWO RECEIVES MORE
SIGNIFICANT FLOODING...REQUIRING A LOCALIZED FLASH FLOOD WARNING.

OTHERWISE...WE SHOULD SEE SCATTERED SHOWERS AND EMBEDDED
THUNDERSTORMS DEVELOP FURTHER NORTH ACROSS MUCH OF SOUTHERN NEW
ENGLAND THIS AFTERNOON.  THERE ARE AT LEAST PEAKS OF SUN IN THIS
REGION AND THIS SHOULD ALLOW FOR MLCAPE VALUES FROM AROUND 1000 TO
1500 J/KG TO DEVELOP.  IN ADDITION...WEAK WARM ADVECTION AND A
RELATIVELY UNCAPPED ATMOSPHERE WILL ASSIST IN SCATTERED SHOWER AND
THUNDERSTORM DEVELOPMENT.  ITS REALLY TOUGH TO PIN AN AREA THAT HAS
A HIGHER RISK OF SEEING MORE WIDESPREAD ACTIVITY.  HOWEVER...SEA
BREEZE FRONT SHOULD DEVELOP ACROSS PORTIONS OF EASTERN MA WHICH MAY
PROVIDE A LITTLE BETTER FOCUS.  ALSO MAYBE SOME TERRAIN INFLUENCES
WILL AID IN THE PROCESS.

MAIN CONCERN WILL BE FOR VERY LOCALLY HEAVY RAINFALL/STREET FLOODING
WITH ANY STORMS...SINCE THEY WILL BE MOVING QUITE SLOW.  WE ALSO CAN
NOT RULE OUT AN ISOLATED FLASH FLOOD EVENT OR TWO IF ACTIVITY CAN
TRAIN OVER A PARTICULAR LOCATIONS.  SEVERE WEATHER THREAT WILL BE
RATHER LIMITED GIVEN VERY WEAK 0 TO 6 KM SHEAR.  HOWEVER...AN
ISOLATED SEVERE THUNDERSTORM OR TWO CAN NOT BE RULED OUT GIVEN
DECENT MLCAPES WITH 500 MB TEMPS AROUND -11C WHICH IS RATHER CHILLY
FOR OUR CURRENT AIRMASS AT THE SURFACE.

HIGH TEMPS THIS AFTERNOON WILL MAINLY BE IN THE UPPER 70S TO THE
MIDDLE 80S.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/...
TONIGHT...

A REPEAT OF LAST NIGHT ANTICIPATED. SCATTERED SHOWER / THUNDERSTORM
ACTIVITY WILL SHIFT E/SE WITH THE MEAN WIND SLOWLY. WHILE DAYTIME
HEATING CONCLUDES...THERE STILL IS A LOT OF INSTABILITY AVAILABLE
WITHIN THE LOW-MID LEVELS ALOFT WHERE LAPSE RATES ARE CONDITIONALLY
UNSTABLE. THREATS OF HEAVY RAIN AND FREQUENT LIGHTNING CONTINUE AND
WITH THE SLOW MOVEMENT OF THE STORM THERE IS A CONCERN FOR LOCALIZED
FLOODING. A MUGGY NIGHT IN STORE WITH LOWS IN THE MID- TO UPPER-
60S. STORM ACTIVITY MAY DISSIPATE TOWARDS MORNING.

TUESDAY...

CONTINUED MID-LEVEL ENERGY THROUGH THE BROADER CYCLONIC FLOW ON WHAT
APPEARS TO BE NNW-SSE FRONTAL BOUNDARY WHEN EVALUATING THE LOW- TO
MID-LEVEL THERMAL PROFILE. SEEMS TO BE SOME LEVEL OF ENHANCED ASCENT
THROUGH THE ATMOSPHERIC LAYER. COLLOCATED JET STREAK AND DECENT NNW-
SSE UNIDIRECTIONAL BULK SHEAR WITH LAPSE RATES EXCEEDING 6C/KM.
SURFACE REFLECTION OF A CONVERGENT BOUNDARY ALONG THE E-COASTLINE
OF NEW ENGLAND APPEARS PLAUSIBLE. WITH A WARM MUGGY AIRMASS STILL
IN PLACE MAY BE DEALING WITH SHOWER / THUNDERSTORM ACTIVITY ACROSS
E- HALF OF NEW ENGLAND...POTENTIALLY LINE-CONVECTION ALONG THE
LEADING EDGE OF THE MID-LEVEL IMPULSE.

CONSIDERING SHEAR / INSTABILITY / INVERTED-V PROFILES WITHIN THE
BOUNDARY-LAYER COULD BE LOOKING AT A MULTI-THREAT OUTCOME WITH ANY
CONVECTION AS IT WOULD APPEAR. GOING TO HAVE TO TAKE A LOOK AT
THIS MORE CLOSELY OVER THE NEXT 24-HOURS. COLLABORATING WITH OTHER
WEATHER FORECAST OFFICES...WILL GO WITH ENHANCED WORDING OF HEAVY
RAIN / GUSTY WINDS / SMALL HAIL. GOOD DEEP- LAYER FORCING AND NEAR
A LOBE OF H5 COLDER AIR DROPPING S WITH THE MID-LEVEL VORTEX.

WITH ANTICIPATED WEATHER / CLOUD COVER PERHAPS SOME ISSUES WITH HIGH
TEMPERATURES. MAYBE AN ONSHORE FLOW ALONG THE E-COAST IF THE ZONE OF
CONVERGENCE HOLDS OVER THE E-HALF OF NEW ENGLAND. WILL LEAN COOLER
IN THIS AREA BUT GO INTO THE UPPER-80S TO THE W.

&&

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

* TRIPLE-H WEATHER WED/THU WITH HIGHS IN 90S.
* SCATTERED STORMS THU/THU NIGHT.
* DRIER BUT STILL VERY WARM FRI THRU SUN.

LARGE SCALE PATTERN FEATURES BUILDING RIDGE OVER NORTHEAST WED/THU
WHICH WILL BRING OUR NEXT SHOT OF HEAT AND HUMIDITY. HOWEVER THIS
SHOULD BE RELATIVELY SHORT LIVED AS UPPER LOW DIGS ACROSS CANADIAN PRAIRIES
AND EVENTUALLY BECOMES CENTERED NEAR HUDSON BAY...RESULTING IN
MORE IN WAY OF CYCLONIC FLOW FOR LATER THIS WEEK INTO NEXT
WEEKEND. STILL LOOKS SUMMERLIKE BEYOND THU BUT CHANGE IN UPPER AIR
PATTERN SHOULD BREAK HUMIDITY AND KEEP TEMPERATURES CLOSER TO
AVERAGE FOR LATE JULY.

WED INTO THU...HIGH CONFIDENCE.

RISING HEIGHTS SHOULD SUPPRESS CONVECTION WED SO AM CONTINUING WITH
DRY FORECAST. NAM SUGGESTION OF DEVELOPMENT ALONG SEA BREEZE FRONT
IS POSSIBLE BUT IS OUTLIER AT THIS POINT. HIGHS SHOULD TOP OUT IN
LOW TO MID 90S AWAY FROM S COAST BUT WITH DEWPOINTS IN MID 60S TO
AROUND 70 HEAT INDICES WILL PROBABLY FALL SHORT OF ADVISORY CRITERIA
/100F FOR 2+ HOURS/.

ANOTHER HOT/HUMID DAY EXPECTED THU BUT HIGHS SHOULD BE SLIGHTLY
LOWER THAN WED GIVEN INCREASING CLOUD COVER AHEAD OF COLD FRONT
APPROACHING FROM GREAT LAKES. DECENT CAPE/0-6KM SHOULD BE PRESENT
ALONG WITH MARGINAL MID LEVEL LAPSE RATES...SO BETTER CHANCE OF
SHOWERS/STORMS DURING AFTERNOON AND EVENING AS FRONT PROVIDES
FOCUS FOR LIFT.

FRI THROUGH SUN...MODERATE CONFIDENCE.

HIGH PRESSURE BUILDS ACROSS NORTHEAST AS UPPER FLOW BECOMES MORE
CYCLONIC. THIS WILL BRING SOME RELIEF FROM HEAT/HUMIDITY BUT HIGHS
SHOULD STILL TOP OUT WELL INTO 80S AWAY FROM S COAST. GOING WITH DRY
FORECAST AS ENSEMBLES SHOW FAIRLY LOW PROBABILITIES OF MEASURABLE
RAINFALL DURING THIS TIME FRAME.

&&

.AVIATION /13Z MONDAY THROUGH FRIDAY/...
FORECASTER CONFIDENCE LEVELS...

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

SHORT TERM /THROUGH TUESDAY/...

NUMEROUS SHOWERS/TSTMS NEAR S COAST WITH MVFR/IFR CIGS/VSBYS WILL
SLOWLY WORK N INTO MA BY EARLY AFTERNOON...BUT ACTIVITY SHOULD
BECOME MORE SCATTERED IN NATURE. OTHERWISE EXPECT VFR CIGS 040-060
TO DOMINATE TODAY WITH LIGHT S/SW WINDS GIVING WAY TO SEA BREEZES
NEAR COAST.

SCATTERED SHOWERS/TSTMS PERSIST TONIGHT WITH MVFR/IFR CIGS/VSBYS.

TUESDAY...LOW-END VFR. FOCUS OVER E-HALF OF S NEW ENGLAND WHERE
RENEWED CHANCES OF SHRA/TSRA. THREATS OF SMALL HAIL / WINDS / +RA
/ LIGHTNING ALL ANTICIPATED. ONSHORE FLOW EXPECTED ALONG E-COAST.

KBOS TERMINAL...MODERATE CONFIDENCE IN TAF.
MAINLY VFR. WEAK SEA BREEZE DEVELOPS LATER THIS MORNING AND VEERS
TO S THIS AFTERNOON. BEST CHANCE OF TSTMS ROUGHLY 19Z-22Z.

KBDL TERMINAL...MODERATE CONFIDENCE IN TAF.
MAINLY VFR. BEST CHANCE OF TSTMS IS ROUGHLY 20Z-22Z BUT CONFIDENCE
IS LOW ACROSS W NEW ENGLAND.

OUTLOOK /TUESDAY NIGHT THROUGH FRIDAY/...

TUESDAY NIGHT AND WEDNESDAY...HIGH CONFIDENCE. MVFR/IFR IN SCT
SHRA/TSRA TUESDAY EVENING...OTHERWISE VFR.

THURSDAY...MODERATE CONFIDENCE. MVFR/IFR IN SCT SHRA/TSRA MAINLY
DURING AFTERNOON AND EVENING.

FRIDAY...MODERATE CONFIDENCE. VFR.

FORECASTER CONFIDENCE LEVELS...

SHORT TERM /THROUGH MONDAY NIGHT/...HIGH CONFIDENCE.

SCATTERED SHOWERS / THUNDERSTORMS TO PERSIST OVER ALL OF THE S NEW
ENGLAND REGION WHICH WILL AT TIMES IMPACT THE WATERS. ANTICIPATE
HEAVY RAIN AND FREQUENT LIGHTNING WITH ANY STORMS. CAN NOT RULE
OUT THE POSSIBILITY OF SMALL HAIL ALONG WITH GUSTY WINDS...THOUGH
THINKING BELOW GALE FORCE. OTHERWISE SEAS REMAINING BELOW 4-FEET
AS WINDS PREDOMINANTLY REMAIN OUT OF THE S.

OUTLOOK /TUESDAY NIGHT THROUGH FRIDAY/...

TUESDAY NIGHT AND WEDNESDAY...HIGH CONFIDENCE.

WINDS AND SEAS REMAIN BELOW SCA. SCA. MAY SEE LEFTOVER
SHOWERS/STORMS ON WATERS DURING EVENING.

THURSDAY...MODERATE CONFIDENCE.

INCREASING S/SW WINDS EXPECTED AHEAD OF COLD FRONT...BUT GUSTS
SHOULD PEAK AROUND 20KT MAINLY ON S COASTAL WATERS. BUILDING S SWELL
MAY REACH 5 FT ON OUTER WATERS S OF ISLANDS. MAY SEE THUNDERSTORMS
LATER IN DAY AND THU EVENING.
