AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
942 AM EDT SUN JUL 27 2014

.SYNOPSIS...
PERIODS OF SHOWERS AND THUNDERSTORMS ARE EXPECTED TODAY THROUGH
MONDAY AS LOW PRESSURE TRACKS FROM THE GREAT LAKES TO NEW ENGLAND
AND EVENTUALLY PUSHES A COLD FRONT THROUGH THE REGION. A FEW
STORMS COULD BE SEVERE ESPECIALLY MONDAY. THE COLD FRONT STALLS
OVER THE MARITIMES AND NEW ENGLAND OFFSHORE WATERS FROM MIDWEEK
THROUGH THE WEEKEND.

&&

.NEAR TERM /THROUGH TONIGHT/...

930 AM UPDATE...

*** WIDESPREAD SEVERE WEATHER APPEARS LESS LIKELY THIS AFTERNOON/
 EVENING...HOWEVER ISOLATED STRONG STORMS ARE POSSIBLE ***

WARM FRONTAL CONVECTION CONTINUES TO PUSH EASTWARD FROM EASTERN NY
INTO WESTERN NEW ENGLAND AT 930 AM. MODELS HANDLING THIS PRECIP
FAIRLY WELL AND TRANSLATE THESE SHOWERS/TSTMS EASTWARD ACROSS THE
REMAINDER OF SOUTHERN NEW ENGLAND THIS MORNING...REACHING EASTERN
MA BETWEEN NOON AND 2 PM...THEN OFFSHORE BY MID AFTERNOON. AS THIS
INITIAL SHORT WAVE TROUGH EXITS THE REGION EARLY THIS AFTERNOON
ALL MODEL GUIDANCE THEN ADVECTS SHORT WAVE RIDGING FROM THE
EASTERN LAKES AND WESTERN NY/PA INTO SOUTHERN NEW ENGLAND. AS THIS
SHORT WAVE RIDGING ADVECTS INTO OUR REGION SO DOES MID LEVEL DRY
WHICH GETS DEEPER WITH TIME LATER THIS AFTERNOON AND EVENING. THIS
WILL ESSENTIALLY PROVIDE A SUBSIDENCE CAP WITH DEEPENING DRY AIR
ALOFT CHOKING/MINIMIZING UPDRAFT POTENTIAL.

IN FACT THIS DEEPENING MID LEVEL DRY AIR AND ASSOCIATED CAP WILL
PRECLUDE SURFACE DEW PTS FROM MIXING OUT AND YIELDING FAIRLY HIGH
SB CAPES VALUES LATER THIS AFTERNOON. HOWEVER LARGE SCALE SUBSIDENCE
AND DEEPENING MID LEVEL DRY AIR SHOULD WIN OUT. NEVERTHELESS THERE
WILL BE A VERY SMALL WINDOW OF OPPORTUNITY FOR STRONG STORMS TO
DEVELOP AND THAT WILL OCCUR IMMEDIATELY BEHIND THE WARM FRONTAL
PRECIP AND ONLY IF SURFACE HEATING CAN COMMENCE QUICKLY BEFORE
SHORT WAVE RIDGING AND ASSOCIATED SUBSIDENCE/MID LEVEL DRY AIR
ARRIVE FROM THE WEST. THUS THE RISK FOR WIDESPREAD STRONG STORMS
IS VERY LOW WITH A SOMEWHAT HIGHER RISK FOR AN ISOLATED STRONG
TSTM MID TO LATE THIS AFTERNOON ACROSS THE INTERIOR.

OTHERWISE NO MAJOR CHANGES TO PREVIOUS FORECAST. EARLIER
DISCUSSION BELOW.

==================================================================

CLOUDS PUSHING INTO W NEW ENGLAND AHEAD OF SHORT WAVE MOVING OUT
OF EASTERN GREAT LAKES. FEW LIGHT SHOWERS/SPRINKLES WEAKENED AS
THEY REACHED BERKSHIRES...AND BULK OF SHOWERS WILL CONTINUE TO
PASS TO OUR N THROUGH SUNRISE.

MEANWHILE STORMS OVER ONTARIO WILL TRACK NE THIS MORNING AS
ADDITIONAL ACTIVITY DEVELOPS ACROSS WESTERN NY PER HIGH-RES
MODELS. FAVORABLE JET DYNAMICS COMBINED WITH APPROACHING SHORT
WAVE WILL YIELD DECENT Q-VECTOR CONVERGENCE AND WILL RESULT IN
BAND OF SHOWER/STORMS CROSSING SOUTHERN NEW ENGLAND THIS MORNING.
BACK EDGE OF THIS ACTIVITY SHOULD REACH CT VALLEY BY MID MORNING
AND E MA COAST BY EARLY AFTERNOON.

CONFIDENCE IS THEN MODERATE AT BEST IN HOW THINGS EVOLVE. CONCERN
IS WHETHER WE CAN DESTABILIZE ENOUGH BEHIND THIS SHORT WAVE TO
PRODUCE A ROUND OF SEVERE STORMS. ON LARGER SCALE SUBSIDENCE
BEHIND DEPARTING SHORT WAVE SHOULD BRING AT LEAST PARTIAL
CLEARING...BUT WOULD ALSO MITIGATE ORGANIZED STORM THREAT.
HOWEVER WITH PLENTY OF INSTABILITY AND LOW LEVEL MOISTURE /DEW
POINTS NEAR 70/ WE THINK AT LEAST A FEW STORMS SHOULD BE ABLE TO
DEVELOP...ALTHOUGH CONDITIONS ARE CERTAINLY MORE FAVORABLE WELL
TO OUR S AND W. WE WILL MAINTAIN CHANCE POPS THIS AFTERNOON FOR
SCATTERED STORMS.

ENVIRONMENT SHOULD FEATURE MODERATE CAPE AND DECENT 0-3KM SHEAR
AND MID LEVEL LAPSE RATES. SHOULD STORMS BE ABLE TO DEVELOP...MAIN
THREATS WOULD BE DAMAGING WINDS AND HAIL. WE CANNOT RULE OUT AN
ISOLATED TORNADO AS WELL IN W NEW ENGLAND WHERE FORECAST HODOGRAPHS
SHOW PLENTY OF TURNING AT LOWER LEVELS. AGREE WITH SPC DAY 1
OUTLOOK.

GIVEN UNCERTAINTY IN HOW MUCH CLEARING WE WILL SEE...LEANED ON
BLEND OF GUIDANCE WHICH GIVES HIGHS IN 70S TO AROUND 80. CERTAINLY
COULD REACH MID 80S SHOULD ENOUGH SUN BREAK OUT.

&&

.SHORT TERM /MONDAY/...

*** LOCALIZED FLASH FLOODING POSSIBLE TONIGHT ***
*** FEW SEVERE STORMS POSSIBLE AGAIN MON ***

CONCERN FOR TONIGHT IS POTENTIAL FOR LOCALIZED FLASH FLOODING AND
PERHAPS STRONG TO SEVERE STORMS...BUT AGAIN CONFIDENCE REMAINS
MODERATE AT BEST IN HOW THINGS EVOLVE.

ONCE ANY STORMS DIMINISH THIS EVENING...ATTENTION TURNS TO
POTENTIAL MCS DEVELOPMENT UPSTREAM ACROSS OHIO VALLEY. HIGHER-RES
MODELS INCLUDING 00Z NAM ARE MORE INSISTENT THAT ITS REMNANTS WILL
TRACK NEAR OR OVER SOUTHERN NEW ENGLAND TONIGHT...PROBABLY NEAR S
COAST IF NOT A BIT FARTHER INLAND. 00Z GFS SEEMS TO BE STRUGGLING
MORE WITH THIS FEATURE...PROBABLY DUE TO ITS COARSER RESOLUTION...
BUT ALSO HINTS AT SOME SORT OF ORGANIZED CONVECTION. WILL MAINTAIN
LIKELY POPS FOR MUCH OF REGION TONIGHT.

OVERALL SEVERE THREAT TONIGHT IS QUESTIONABLE AS WE REMAIN
UNSTABLE BUT 0-3KM SHEAR AND LAPSE RATES DROP OFF A BIT. CERTAINLY
MAIN THREAT APPEARS TO BE HEAVY RAIN WITH PLENTIFUL LOW LEVEL
MOISTURE. FLASH FLOOD THREAT DOES NOT APPEAR TO BE WIDESPREAD
ENOUGH TO ISSUE ANY WATCHES AT THIS TIME...NOR DO WE HAVE
CONFIDENCE IN GREATEST THREAT AREA.

UPPER LOW CUTS OFF TO OUR W MON AS SURFACE LOW LIKELY PASSES JUST
TO OUR W. THIS SHOULD FOCUS MOST OF SHOWERS/STORMS TO OUR W AND N
WHERE BETTER LARGE SCALE FORCING RESIDES. WE MAY EVEN END UP WITH
A DRY SLOT ACROSS SE NEW ENGLAND BUT PERSISTENT S/SW FLOW SHOULD
MAINTAIN CLOUDINESS THERE. ONCE AGAIN THERE ARE QUESTIONS AS TO
HOW MUCH CLEARING WE ACTUALLY SEE AND IF THAT GENERATES ENOUGH
INSTABILITY FOR ADDITIONAL STORM DEVELOPMENT MON AFTERNOON. IF
STORMS CAN DEVELOP...ENVIRONMENT WOULD FEATURE DECENT MID LEVEL
LAPSE RATES AND STRONG 0-3KM SHEAR WHICH WOULD SUPPORT A FEW
SEVERE STORMS.

DUE TO CONTINUED UNCERTAINTY...USED BLEND OF GUIDANCE WHICH GIVES
HIGHS IN 70S TO AROUND 80.

&&

.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
BIG PICTURE...

MODELS CONTINUE TO ADVERTISE A MERIDIONAL TYPE FLOW THROUGH THE
UPCOMING WEEK. FOUR LOBES OF THIS FLOW ARE THE GULF OF ALASKA
TROUGH...WESTERN NORTH AMERICA RIDGE...EASTERN NORTH AMERICA
TROUGH...AND WEST ATLANTIC RIDGE. THE EFFECT OF THIS PATTERN WILL BE
TO BRING SIMILAR WEATHER EACH DAY.

MODELS CONTINUE TO SHOW THE CORE OF THE EASTERN NO-AM TROUGH
EJECTING NORTH THROUGH QUEBEC FRIDAY AND SATURDAY. THIS MAY LEAVE
ROOM FOR THE ATLANTIC RIDGE TO SHIFT WEST BY SATURDAY.

THE SIMILARITY IN MODEL FIELDS FAVORS A BLEND OF AVAILABLE DATA.

THE DAILIES...

MONDAY NIGHT... SURFACE LOW PRESSURE LIFTS NORTH INTO CANADA...ALL
THE WHILE SWINGING A COLD FRONT ACROSS THE REMAINDER OF SOUTHERN NEW
ENGLAND AND THEN OFFSHORE. WINDS SHIFT TO WEST AND BECOME LIGHT. THE
AIRMASS WILL STABILIZE AND FAVORABLE DYNAMICS WILL MOVE OFF. EVENING
SHOWERS/THUNDERSTORMS WILL TAPER OFF AT NIGHT.  SUFFICIENT AIRMASS
DRYING IS INDICATED TO SUPPORT A CLEARING TREND OVERNIGHT.

TUESDAY THROUGH FRIDAY... WITH THE UPPER TROUGH TO OUR WEST AND
UPPER RIDGE TO OUR EAST...EXPECT THE UPPER FLOW TO REMAIN FROM THE
SOUTHWEST. THE DEPARTED COLD FRONT WILL STALL OVER THE MARITIMES AND
THE OFFSHORE WATERS.  MEANWHILE COLD POOL INSTABILITY UNDER THE
UPPER TROUGH WILL BE OVER NY AND ONTARIO WHILE NEW ENGLAND IS UNDER
THE LEFT ENTRANCE REGION OF THE UPPER JET...A SUBSIDENT ZONE.
SURFACE HIGH PRESSURE WILL BUILD OVER SOUTHERN NEW ENGLAND.

THIS WILL MEAN A CHANCE OF SHOWERS WELL OFFSHORE AND OVER NY/ONTARIO
WITH DRY WEATHER OVER SOUTHERN NEW ENGLAND.  IF THE UPPER FEATURES
SHIFT A LITTLE FURTHER EAST OR WEST...THEN IT IS POSSIBLE WE COULD
HAVE A CHANCE OF SHOWERS IN PART OF SOUTHERN NEW ENGLAND. BUT DRY
WEATHER IS THE LIKELY SCENARIO.

SATURDAY... AS THE UPPER TROUGH LIFTS NORTH...EXPECT THE OFFSHORE
FRONT TO SHIFT WEST CLOSER TO THE COAST.  THIS SHOULD BRING AN
INCREASE IN THE CHANCE OF SHOWERS...WITH THE BEST CHANCE ON THE CAPE
AND ISLANDS.

&&

.AVIATION /13Z SUNDAY THROUGH THURSDAY/...
FORECASTER CONFIDENCE LEVELS...

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

MODERATE CONFIDENCE THROUGH MON.

930 AM UPDATE...

ONLY CHANGE TO PREVIOUS FORECAST IS AFTER LATE MORNING/EARLY
AFTERNOON SHOWERS/TSTMS...WIDESPREAD STRONG STORMS LATE THIS
AFTERNOON/EARLY EVENING APPEAR LESS LIKELY. OTHERWISE FORECAST
REMAINS UNCHANGED. EARLIER DISCUSSION BELOW.

===============================================================

ACTIVITY OVER ONTARIO AND W NY IS EXPECTED TO AFFECT MUCH OF
REGION THIS MORNING. CIGS REMAIN VFR WITH THIS ACTIVITY BUT VSBYS
SHOULD LOWER TO MVFR. BACK EDGE MOVES OUT OF CT VALLEY BY 15Z AND
E MA COAST AROUND 18Z.

VFR CIGS AOA 050 REMAIN IN ITS WAKE THIS AFTERNOON. POTENTIAL FOR
ADDITIONAL SCATTERED SHOWERS/STORMS TO DEVELOP ESPECIALLY IN W NEW
ENGLAND WITH BRIEF MVFR/IFR.

IFR/LIFR CIGS/VSBYS BECOME MORE WIDESPREAD TONIGHT...FIRST ALONG S
COAST...CAPE COD AND ISLANDS AROUND SUNSET BEFORE SPREADING
INLAND. ALSO EXPECT NUMEROUS SHOWERS/STORMS WITH HEAVY RAINFALL.

CONDITIONS SLOWLY IMPROVE AFTER 12Z MON AS FOCUS FOR
SHOWERS/STORMS SHIFTS N AND W OF REGION.

KBOS TAF...MODERATE CONFIDENCE. PREVAILING SW FLOW. SHOWERS/STORMS
MOST LIKELY 15Z-18Z.

KBDL TAF...MODERATE CONFIDENCE. SHOWERS/STORMS MOST LIKELY
13Z-15Z WITH SCATTERED STORMS POSSIBLE AFTER 19Z.

OUTLOOK...MONDAY NIGHT THROUGH THURSDAY...MODERATE CONFIDENCE.

MONDAY NIGHT...LINGERING AREAS OF MVFR/IFR IN THUNDERSTORMS.
OTHERWISE VFR OR TRENDING TO VFR.  WINDS SHIFT TO WEST AND DIMINISH.

TUESDAY...VFR BUT WITH ISOLATED MVFR IN SHOWERS/TSTMS MAINLY SRN NEW
HAMPSHIRE AND WESTERN/CENTRAL MASS IN THE AFTERNOON/EVENING.

WEDNESDAY-THURSDAY...VFR.

.MARINE...
FORECASTER CONFIDENCE LEVELS...

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

MODERATE CONFIDENCE TODAY THROUGH MON.

SCA REMAINS POSTED TODAY FOR ALL WATERS DUE TO INCREASING SW FLOW
WITH GUSTS TO 25 KT...ESPECIALLY NEAR SHORE. THIS WILL ALSO
PRODUCE BUILDING SEAS TO 5 FT ON OUTER WATERS. SHOWERS AND STORMS
EXPECTED LATER THIS MORNING WITH ADDITIONAL STORMS POSSIBLE DURING
AFTERNOON.

SW WINDS DROP OFF A BIT TONIGHT AND MON BUT SEAS CONTINUE TO
BUILD ON OUTER WATERS TO 6 OR 7 FT. SHOWERS/STORMS SHOULD BECOME
MORE WIDESPREAD WITH AREAS OF FOG TONIGHT...BEFORE CONDITIONS
GRADUALLY IMPROVE MON.

OUTLOOK...MONDAY NIGHT THROUGH THURSDAY...MODERATE CONFIDENCE.

MONDAY NIGHT... COLD FRONT MOVES OVER THE WATERS. SOUTHWEST WINDS IN
THE EVENING WILL GUST TO 25 KNOTS...BUT SHOULD DIMINISH AFTER THE
COLD FRONT MOVES THROUGH AND WINDS SHIFT TO WEST.  SEAS 5-7 FEET IN
THE EVENING SHOULD SUBSIDE AFTER THE WIND SHIFT.

TUESDAY...WINDS AND SEAS WILL CONTINUE TO SUBSIDE AS THE COLD FRONT
SHIFTS EAST OF THE WATERS.  SEAS AT 5 FEET MAY LINGER ON THE OUTER
WATERS FOR PART OF THE DAY.

WEDNESDAY-THURSDAY...LIGHTER WINDS AND SEAS AS HIGH PRESSURE BUILDS
OVER THE WATERS.
