AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
1110 AM EDT THU JUL 3 2014

.SYNOPSIS...
VERY MOIST AND RATHER UNSTABLE AIR MASS AHEAD OF A SLOW MOVING FRONT
WILL SET THE STAGE FOR SCATTERED SHOWERS AND THUNDERSTORMS INTO
THIS EVENING...ESPECIALLY ACROSS THE WESTERN HALF OF THE AREA.
MORE WIDESPREAD SHOWERS/THUNDERSTORMS WITH LOCALLY HEAVY RAINFALL
ARE EXPECTED FRIDAY. TROPICAL STORM ARTHUR WILL PASS SOUTHEAST OF
OUR REGION FRIDAY NIGHT INTO SATURDAY HAVING A SIGNIFICANT IMPACT
ON THE MARINE COMMUNITY. HIGH PRESSURE THEN BUILDS OVER NEW
ENGLAND WITH FAIR AND DRY WEATHER FOR THE WEEKEND.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
WARM VERY HUMID AIRMASS WITH DEWPOINTS IN THE LOWER 70S. MORE
CLOUDS AROUND THAN WAS THE CASE YESTERDAY SO TEMPS ARE EXPECTED TO
TOP OUT IN THE 80S. BUT SB CAPES ARE ALREADY TO 1000 J/KG AND MAY
GROW LARGER.

MAIN ISSUES FOR TODAY CONTINUE TO BE SEVERE POTENTIAL AND FLASH
FLOOD POTENTIAL. SBCAPES FORECAST AT 1500 TO 2000 J/KG THIS
AFTERNOON AND OTHER CONVECTIVE INDICES INDICATE AT LEAST MODERATE
INSTABILITY COMBINED WITH 0-6 KM SHEAR 35 TO 40 KT GENERALLY CT
VALLEY AND WEST. MOST OF INTERIOR SOUTHERN NEW ENGLAND IS IN A
SLIGHT RISK AREA. DO NOT THINK ENOUGH FOCUS FOR A WIDESPREAD
OUTBREAK BUT COULD SEE A FEW STRONG TO SEVERE TSTMS W OF A LWM-
ORH-IJD LINE. WITH REGARD TO FLASH FLOOD POTENTIAL...SURFACE
FRONTAL BOUNDARY AND UPPER RIGHT ENTRANCE REGION OF JET GRADUALLY
APPROACHING BUT STILL W OF OUR CWA. HOWEVER...AS WAS THE CASE
YESTERDAY...HAVE HIGH PWATS NEAR 2 INCHES AND POTENTIAL EXISTS FOR
VERY HIGH RAFL RATES WITH RISK OF 2 OR 3 CELLS PASSING OVER AN
AREA IN SUCCESSION. FLASH FLOOD WATCH CONTINUES IN WESTERN MASS
AND SOUTHWEST NH WHICH ARE CLOSER TO THE FOCUSING MECHANISMS. THIS
AREA ALSO HAD THE HEAVIER RAINFALL YESTERDAY. WE MAY NEED TO
EXPAND THE WATCH EAST AND SOUTH DURING THE AFTERNOON AS CONVECTION
GEARS UP.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM FRIDAY/...
WILL BE WARM AND MUGGY WITH MOST LOW TEMPS VERY HIGH 60S TO LOWER
70S. EXPECT FAIRLY WIDESPREAD LOW CLOUDINESS AND AREAS OF FOG SE
COASTAL SECTIONS AND PERHAPS CT VALLEY. MAY HAVE A SEVERE THREAT
EARLY BUT MAIN ISSUE FOR TONIGHT WILL BE RISK OF MORE DOWNPOURS.
HAVE SET THE FLASH FLOOD WATCH TO GO UNTIL MIDNIGHT. AFTER
MIDNIGHT...CONSENSUS OF MODELS POINT TO START OF WHAT MAY EVOLVE
INTO THE MAIN HEAVY RAIN EVENT FOR A LARGER PART OF OUR AREA.
ANTICIPATING LATE TONIGHT FOR THE RIGHT ENTRANCE REGION OF THE
UPPER JET TO BECOME A BIGGER PLAYER ALONG WITH APPROACH OF THE
SURFACE FRONTAL BOUNDARY AND ASSOCIATED LOW LEVEL MOISTURE
CONVERGENCE. IN ADDITION...THINK WE MAY SEE PLUME OF MOISTURE FROM
ARTHUR WORKING ITS WAY ALONG THE MID ATLC COASTAL PLAIN INTO
SOUTHERN NEW ENGLAND...PERHAPS INITIALLY CT AND THEN SPREADING
EASTWARD TOWARD MORNING. NOT REAL CONFIDENT YET JUST HOW THIS WILL
PLAY OUT BUT THINK MAY SEE MORE ORGANIZED BAND OR BANDS OF HEAVY
SHOWERS/EMBEDDED TSTMS DEVELOP SW TO NE INTO SOUTHERN NEW ENGLAND
LATE TONIGHT/EARLY FRIDAY.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
HIGHLIGHTS...
* TROPICAL STORM ARTHUR LIKELY TO PASS SOUTHEAST OF US FRI NIGHT-SAT
* HIGH PRESSURE RETURNS FOR THE WEEKEND
* INCREASING HEAT AND HUMIDITY EARLY NEXT WEEK

HAVE SPENT THE MAJORITY OF TIME ON THE FRIDAY TO SATURDAY TIME FRAME
FOCUSING ON ARTHUR DUE TO LIMITED RESOURCES.  A BLEND OF AVAILABLE
MODEL GUIDANCE APPEARS ADEQUATE IN FAIRLY QUIET WEATHER LATE THIS
WEEKEND INTO EARLY NEXT WEEK.

THE MODELS ARE IN DECENT AGREEMENT ON THE GENERAL SYNOPTIC PATTERN
AS WELL AS THE TRACK OF ARTHUR.  HOWEVER...THERE ARE STILL
DIFFERENCES IN BOTH TRACK AND INTENSITY.  THE 03/00Z GFS IS THE
FARTHEST NORTHWEST TRACK...PASSING JUST BARELY SOUTH OF THE 40/70
BENCHMARK LATE FRIDAY NIGHT INTO SATURDAY MORNING.  THE 03/00Z NAM
IS THE FARTHEST OUTSIDE THE BENCHMARK AND THE 03/12Z ECMWF LAYS IN
BETWEEN AND IS THE CLOSEST TO THE NATIONAL HURRICANE CENTER
FORECAST.  THIS TRACK BRINGS ARTHUR NORTHEAST FROM THE CAROLINAS...
PASSING ABOUT 50 MILES SOUTHEAST OF THE 40/70 BENCHMARK.  THE NHC
TRACK ALSO IS REASONABLY WELL MODELED BY THE 03/12Z GEFS MEAN AND
THE OTHER GLOBAL MODELS.  NEEDLESS TO SAY...THERE IS STILL SOME
UNCERTAINTY ON THE EXACT IMPACTS ARTHUR WILL HAVE ON SOUTHERN NEW
ENGLAND.

FRIDAY /8 AM TO 8 PM/...SHOWERS AND THUNDERSTORMS ARE LIKELY TO
CONTINUE ACROSS SOUTHERN NEW ENGLAND THROUGH THE MORNING AND INTO
THE EARLY AFTERNOON AT LEAST AS A COLD FRONT MARCHES THROUGH
SOUTHERN NEW ENGLAND.  THERE REMAINS PLENTY OF MOISTURE IN THE
REGION AS TROPICAL MOISTURE CONTINUES TO GET FED UP THE EAST COAST
FROM ARTHUR.  THE QUESTION REMAINS HOW MUCH INSTABILITY WILL REMAIN
AFTER TWO DAYS OF THUNDERSTORMS /WEDNESDAY AND THURSDAY/. MODELS ARE
INDICATING SOME MODEST INSTABILITY REMAINING BUT MUCH WILL REMAIN
UNCERTAIN UNTIL WE SEE WHERE THUNDERSTORMS OCCUR TODAY.  THE DAYTIME
PERIOD IS NOT EXPECTED TO BE A WASHOUT THOUGH.  THERE WILL BE
PERIODS OF DRY WEATHER...THOUGH IT WILL BE OVERCAST AND VERY MUGGY.

ARTHUR WILL MAKE HIS WAY UP THE EAST COAST DURING THE DAY FRIDAY.
HOW QUICKLY HE MOVES UP TOWARDS SOUTHERN NEW ENGLAND DEPENDS UPON
HOW HE INTERACTS WITH THE MID LEVEL TROUGH MOVING TOWARDS SOUTHERN
NEW ENGLAND FROM THE GREAT LAKES.  AT THE MOMENT...MODELS INDICATE
HE WILL BE JUST EAST OF THE DELMARVA PENINSULA BY 8 PM.  WE SHOULD
ALREADY BE SEEING SOME RAIN FROM ARTHUR...DEPENDING ON TRACK...
MAINLY ACROSS RI AND SE MA.

FRIDAY NIGHT /8 PM TO 8 AM/...WHAT IS FORECAST TO BE HURRICANE
ARTHUR BY THIS POINT WILL MAKE HIS CLOSEST PASS TO SOUTHERN NEW
ENGLAND SOMETIME DURING THE OVERNIGHT PERIOD.  AS DISCUSSED ABOVE...
THERE IS SOME UNCERTAINTY WITH THE EXACT TRACK.  HOWEVER...THE
CURRENT FORECAST TRACK OF THE STORM /PASSING ABOUT 50 MILES
SOUTHEAST OF THE 40/70 BENCHMARK/ WILL RESULT IN A MAINLY MARINE
IMPACT.  VERY HEAVY RAIN IS LIKELY ACROSS ALL OF SOUTHERN NEW
ENGLAND WITH THE HIGHEST AMOUNTS FOCUSED ACROSS EASTERN
MASSACHUSETTS AND RHODE ISLAND.  THE CAPE AND ISLANDS WILL LIKELY
SEE SOME TROPICAL STORM FORCE WIND GUSTS /34 KTS OR GREATER/ DURING
THE OVERNIGHT HOURS.  OTHERWISE...THE HIGHER WINDS WOULD REMAIN WELL
OFFSHORE ON THE EASTERN SIDE OF THE STORM.

SATURDAY...ARTHUR CONTINUES TO MOVE TO THE NORTHEAST...EVENTUALLY
BECOMING ABSORBED IN THE MID LEVEL TROUGH OVER NOVA SCOTIA.  HEAVY
RAIN AND GUSTY WINDS EARLY ALONG THE EAST COAST WILL MOVE OFFSHORE
LIKELY BY MID-MORNING AND DEFINITELY BY NOON.  SKIES WILL CLEAR AS
HIGH PRESSURE BUILDS IN BEHIND THE COLD FRONT.  DRIER AIR MOVES IN
AND WITH COOLER TEMPERATURES THE REST OF THE AFTERNOON SHOULD BE
NICE AND FRESH.

SATURDAY NIGHT AND SUNDAY...HIGH PRESSURE CONTINUES TO DOMINATE
THROUGH THE REMAINDER OF THE WEEKEND.  QUIET AND DRY WEATHER IS
EXPECTED.

MONDAY THROUGH WEDNESDAY...EXPECT INCREASING HEAT AND HUMIDITY
MONDAY AND TUESDAY AS SOUTHWESTERLY SURFACE WINDS RETURN.  A COLD
FRONT LATE TUESDAY MAY BRING SHOWERS AND THUNDERSTORMS BEFORE COOLER
DRIER WEATHER RETURNS WEDNESDAY.

&&

.AVIATION /15Z THURSDAY THROUGH MONDAY/...
FORECASTER CONFIDENCE LEVELS...

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

MODERATE CONFIDENCE WITH CONSIDERABLE VARIABILITY IN SPACE AND TIME.

LINGERING IFR IN FOG AND STRATUS ALONG THE SOUTH COAST ESPECIALLY
AROUND THE CAPE AND ISLANDS. EXPECT THESE LOWER CONDITIONS SLOWLY
IMPROVING TO VFR MOST AREAS MIDDAY OR EARLY AFTERNOON. CONDITIONS
LOWERING AGAIN TONIGHT WITH NUMEROUS AREAS OF IFR CIGS DUE TO
LOW CLOUDS AND IFR VSBYS IN FOG DEVELOPING.

A FEW TSTMS W OF A MHT-ORH-IJD LINE MAY CONTAIN STRONG SURFACE
WIND GUSTS AND IFR CONDITIONS IN HEAVY RAIN DURING THE AFTERNOON
AND EVENING.

KBOS TAF...MODERATE CONFIDENCE. CIGS NEAR MVFR/IFR THRESHOLD SHOULD
RETURN AGAIN TONIGHT. SCT TSTMS...MAINLY W OF BOS THIS AFTERNOON/EVENING.

KBDL TAF...MODERATE CONFIDENCE. RISK OF MVFR CIGS SHOULD IMPROVE
TO VFR THIS AFTERNOON AND THEN LOWER AGAIN TONIGHT. SCT TSTMS IN
AREA THIS AFTERNOON AND EVENING. MORE CONCENTRATED SHOWER ACTIVITY
POSSIBLE LATE TONIGHT WITH MVFR CIGS AND VSBYS IN THE RAIN AND
FOG.

OUTLOOK...FRIDAY THROUGH MONDAY...

FRIDAY...LOW CONFIDENCE.  MVFR/IFR CONDITIONS LIKELY IN LOW
CLOUDS...FOG...AND HEAVY RAIN.

FRIDAY NIGHT THROUGH 18Z SATURDAY...LOW CONFIDENCE.  MVFR/IFR
CONDITIONS LIKELY IN LOW CLOUDS...FOG...AND HEAVY RAIN. TROPICAL
STORM FORCE WINDS POSSIBLE ON THE CAPE AND ISLANDS BETWEEN 00Z AND
18Z SATURDAY.

18Z SATURDAY THROUGH MONDAY...HIGH CONFIDENCE.  MAINLY VFR.

&&

.MARINE...
FORECASTER CONFIDENCE LEVELS...

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

AREAS OF FOG LINGERING ALONG THE SOUTH COAST BUT SHOULD SLOWLY
LIFT THIS AFTERNOON.

WINDS SHOULD REMAIN RELATIVELY LIGHT IN THE SHORT TERM BUT
INCREASING SOUTHERLY SWELL HAS TRIGGERED NEED FOR SMALL CRAFT
ADVISORY FOR OUTER S COAST WATER TONIGHT...WHERE SEAS ARE EXPECTED
TO BUILD TO 5 FT. PATCHY NIGHT/MORNING FOG ACROSS THE
WATERS...ESPECIALLY THE SOUTH COASTAL WATERS.

AFTER COORDINATION WITH THE HURRICANE CENTER AND OCEAN PREDICTION
CENTER...WE WILL BE ISSUING A TROPICAL STORM WARNING FOR THE
COASTAL WATERS OUTSIDE OF NANTUCKET. THESE ARE ANZ254 AND ANZ255.
TROPICAL STORM FORCE WINDS POSSIBLE ON THESE WATERS WITHIN 36
HOURS. VALID TIME WILL BE 01Z-08Z.

OUTLOOK...FRIDAY THROUGH MONDAY...

FRIDAY...MODERATE CONFIDENCE. PERSISTENT LONG SOUTH TO SOUTHWEST
FETCH SHOULD YIELD SCA SEAS...BETWEEN 3 AND 6 FT...ACROSS MOST OF
THE OUTER WATERS.  SMALL CRAFT ADVISORIES HAVE BEEN ISSUED FOR THE
SOUTHERN OUTER WATERS.  THESE MAY NEED TO BE EXTENDED FOR THE
EASTERN OUTER WATERS AS WELL LATER TODAY. THERE IS A RISK OF
FOG...PARTICULARLY DURING THE EARLY MORNING HOURS WITH DEEP LOW
LEVEL MOISTURE IN PLACE. IN ADDITION...HEAVY RAIN IS POSSIBLE AT
TIMES.

FRIDAY NIGHT AND SATURDAY...LOW CONFIDENCE.  TROPICAL STORM ARTHUR
IS FORECAST TO PASS NEAR THE BENCHMARK TOWARD DAYBREAK SATURDAY.
THIS WILL BRING A PERIOD OF HIGH SEAS AND STRONG WINDS TO THE
SOUTHEAST WATERS FRI NIGHT INTO SATURDAY.  THIS SYSTEM IS LIKELY TO
HAVE A SIGNIFICANT IMPACT ON THE MARINE COMMUNITY.  WINDS AND SEAS
DIMINISH SLOWLY SATURDAY AFTERNOON AS ARTHUR MOVES AWAY FROM THE
REGION.

SATURDAY NIGHT THROUGH SUNDAY...MODERATE CONFIDENCE.  QUIET BOATING
WEATHER.

SUNDAY NIGHT THROUGH MONDAY...LOW CONFIDENCE.  EXPECT INCREASING
SEAS ON THE OUTER WATERS WITH SMALL CRAFT SEAS LIKELY.

&&

.HYDROLOGY...
THE ATMOSPHERE IS JUICY WITH PRECIP WATER VALUES 1.7 TO 2.0
INCHES. WITH NO SIGNIFICANT CHANGE EXPECTED THROUGH FRIDAY
NIGHT...THERE IS THE POTENTIAL FOR SHOWERS AND THUNDERSTORMS
PRODUCING HEAVY RAINFALL THROUGH THIS TIME. THIS WILL MEAN A
CHANCE FOR URBAN AND SMALL STREAM FLASH FLOODING. RIVERS AND
STREAMS ARE GENERALLY AT NORMAL LEVELS FOR THIS TIME OF
YEAR...EXCEPT BELOW NORMAL ACROSS EASTERN MA AND NORTHERN RI.
BECAUSE OF THIS...LARGER TRIBUTARY AND MAINSTEM RIVERS WOULD BE
MORE DIFFICULT TO FLOOD.

A FLASH FLOOD WATCH CONTINUES THIS AFTERNOON AND EVENING ACROSS
PORTIONS OF WESTERN MASSACHUSETTS AND SOUTHWESTERN NEW HAMPSHIRE.
THIS MAY NEED TO BE EXPANDED AS CONVECTION FIRES UP.

FLASH FLOOD WATCHES WILL LIKELY BE NEEDED FOR AT LEAST SE HALF OF
AREA FOR FRIDAY BUT WILL WAIT TIL THIS EVENING BEFORE PULLING
TRIGGER ON THAT.

&&
