AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
1033 AM EDT WED JUL 2 2014

.SYNOPSIS...
VERY HUMID CONDITIONS WILL CONTINUE THROUGH THE END OF THE WEEK.
SCATTERED STRONG THUNDERSTORMS ARE POSSIBLE IN THE INTERIOR TODAY
WITH MORE WIDESPREAD SHOWERS/THUNDERSTORMS WITH LOCALLY HEAVY
RAINFALL EXPECTED THURSDAY AND FRIDAY. TROPICAL STORM ARTHUR WILL
PASS SOUTHEAST OF OUR REGION FRIDAY NIGHT INTO SATURDAY...PERHAPS
HAVING A SIGNIFICANT IMPACT ON THE MARINE COMMUNITY.

&&

.NEAR TERM /THROUGH TONIGHT/...

10 AM UPDATE...
LINGERING LOW CLOUDS ALONG THE SOUTH COAST...BUT WITH A THINNING
TREND. OTHERWISE MOSTLY SUNNY AROUND THE REGION. TEMPERATURES ARE
CLIMBING...AND WERE 1-3F WARMER THAN THE FORECAST AT MID MORNING.

SURFACE AND UPPER RIDGE ARE OFFSHORE WITH SOUTHWEST FLOW ACROSS
SOUTHERN NEW ENGLAND. DEWPOINTS ARE IN THE UPPER 60S AND LOW 70S.
PRECIP WATER VALUES CURRENTLY BELOW 1.5 INCHES BUT WITH 1.5 TO 2
INCH VALUES ACROSS PA AND LONG ISLANDS POISED TO MOVE NORTH. CAPES
ARE BUILDING...AT MID MORNING THERE WAS STILL A FAIR AMOUNT OF CIN
IN PLACE BUT THIS SHOULD CHANGE BY AFTERNOON.

SURFACE TROUGH OVER CENTRAL NY/PA THIS MORNING WILL MOVE EAST INTO
SOUTHERN NEW ENGLAND THIS AFTERNOON. SB CAPES ARE CLIMBING AND
SHOULD REACH NEAR 2000 J/KG IN THE INTERIOR. MID LEVEL LAPSE RATES
AROUND 6C/KM OVER NEW ENGLAND AND 6.5C/KM OVER NEW YORK. SYNOPTIC
FORCING VIA THE UPPER JET...THIS REMAINS FARTHER WEST OVER WESTERN
NY/PA. SO NOT EVERYTHING IS IDEAL FOR CONVECTION...BUT ENOUGH IS
THERE FOR SCATTERED TSTMS TO DEVELOP. CONDITIONS BECOME MORE
FAVORABLE LATER IN THE AFTERNOON AND SPREAD FARTHER EAST BY
EVENING. WE CONTINUE TO INCLUDE EXTRA WORDING IN THE FORECAST FOR
STRONG WIND GUSTS AND SMALL HAIL. WINDS ALOFT FAVOR A CONVECTIVE
MODE OF MULTICELL LINES...SO WIND EVENTS ARE FAVORED OVER HAIL
EVENT. NOTE THAT SPC HAS EXPANDED EAST THE SLIGHT RISK AREA FOR
SEVERE WEATHER. WE HAVE ALSO EXPANDED CHANCE POPS A LITTLE EAST OF
OUR PREVIOUS MANCHESTER-WORCESTER LINE.

MORNING OBSERVED 850 MB TEMPS SHOWED 18C WITH EQUIV TEMPS
ELSEWHERE IN THE MIXED LAYER. THIS WOULD FAVOR MAX SFC TEMPS IN
THE UPPER 80S AND LOW 90S. LATE MORNING OBSERVED TEMPS WOULD FAVOR
TEMPS IN THE 90S AWAY FROM THE IMMEDIATE COAST. SOUTH TO SOUTHWEST
WINDS MAY BUFFER THE HEAT THIS AFTERNOON ALONG THE SOUTH COAST AN
UNDETERMINED DISTANCE INLAND. HEAT INDEX VALUES INLAND SHOULD BE
IN THE MID 90S.

&&

.SHORT TERM /THURSDAY/...
TONIGHT...
EXPECT ONGOING CONVECTION IN THE EVENING IN THE INTERIOR
AND IT IS POSSIBLE SCT SHOWERS/TSTMS WILL MOVE EAST ACROSS SNE
DURING THE NIGHT AS GEFS ENSEMBLE INDICATE SFC INSTABILITY AXIS
MOVING EAST WITH SFC FRONT APPROACHING FROM THE WEST. LOCALLY
HEAVY DOWNPOURS WILL BE THE PRIMARY THREAT.

IT WILL BE A WARM AND HUMID NIGHT WITH AREAS OF STRATUS AND FOG
DEVELOPING...ESPECIALLY ALONG THE S COAST. MINS UPPER 60S TO LOWER
70S.

THURSDAY...
POTENTIAL BEGINNING OF A PRE AS TROPICAL MOISTURE AHEAD OF ARTHUR
SURGES NORTHWARD AND INTERACTS WITH COLD FRONT WHICH WILL BE JUST
WEST OF SNE. HOWEVER...RIGHT ENTRANCE REGION OF WELL DEFINED UPPER
JET IS STILL TO THE WEST AND IT IS POSSIBLE A PRE AND ANY ORGANIZED
HEAVY RAINFALL WILL WAIT UNTIL THU NIGHT/FRI WHEN THE UPPER JET
APPROACHES. REGARDLESS OF WHETHER WE HAVE AN ORGANIZED PRE ON
THURSDAY...VERY MOIST ENVIRONMENT WITH PWATS NEAR 2" AND DEWPOINTS
LOW/MID 70S WITH CAPES 1000-2000 J/KG SUGGEST A HIGH PROBABILITY OF
AT LEAST SCT TSTMS WITH LOCALLY VERY HEAVY RAINFALL AND POTENTIAL
FOR FLASH FLOODING. INSTABILITY EXTENDS FURTHER EAST ON THU SO
TSTM THREAT WILL EXTEND INTO THE COASTAL PLAIN.

CLOUD COVER AND MORE NUMEROUS SHOWERS/TSTMS WILL KEEP TEMPS MOSTLY
IN THE LOW TO MID 80S WITH UPPER 70S ALONG THE S COAST.

&&

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

* POTENTIAL PREDECESSOR HEAVY RAIN/FLOOD EVENT THU INTO FRI AFTERNOON
* TROPICAL STORM ARTHUR MAY PASS SOUTHEAST OF US FRI NIGHT-SAT
* HIGH PRESSURE RETURNS FOR THE WEEKEND
* INCREASING HEAT AND HUMIDITY EARLY NEXT WEEK

THE MODELS ARE IN DECENT AGREEMENT THROUGH THE END OF THE WEEK.
HOWEVER...THE ECMWF AND THE GFS HAVE LOST THE AGREEMENT THEY ONCE
HAD ON THE TRACK OF TROPICAL STORM ARTHUR.  THE 00Z GFS KEEPS ARTHUR
CLOSER TO THE SOUTHERN NEW ENGLAND COAST THAN EITHER THE NHC TRACK
OR THE 01/12Z ECMWF.  THE ECMWF TRACKS ARTHUR EAST NORTHEASTWARD
FROM THE CAROLINA COAST...PASSING WELL SOUTH OF THE 40/70 BENCHMARK.
THE NHC TRACK...INCORPORATING THESE TRACKS AS WELL AS A HOST OF
OTHER MODELS ENCOMPASSES THE WHOLE ENVELOPE OF SOLUTIONS
POSSIBLE...WITH THE OFFICIAL TRACK NEAREST TO THE UKMET AND CANADIAN
TRACKS. THE ECMWF TRACK WOULD RESULT IN MAINLY A MARINE IMPACT WHILE
THE GFS SOLUTION WOULD BRING MORE IMPACTS TO THE SOUTHERN NEW
ENGLAND COASTLINE.  NEEDLESS TO SAY...THERE IS STILL SIGNIFICANT
UNCERTAINTY ON THE EXACT IMPACTS ARTHUR WILL HAVE ON SOUTHERN NEW
ENGLAND.  AHEAD OF ARTHUR...THERE IS POTENTIAL FOR A PREDECESSOR
HEAVY RAIN EVENT THURSDAY INTO FRIDAY MORNING. MODELS DO NOT USUALLY
HANDLE THESE EVENTS WELL AT ALL...AND THIS IS NO EXCEPTION...THOUGH
ALL HAVE SOME RAIN OCCURRING WITHIN THE CWA DURING THIS TIME FRAME.
HOWEVER...AMOUNTS VARY SIGNIFICANTLY.  MORE INFORMATION FOLLOWS.

THURSDAY NIGHT AND FRIDAY...THIS PORTION OF THE FORECAST IS VERY LOW
CONFIDENCE. TROPICAL STORM ARTHUR IS EXPECTED TO MAKE ITS NEAREST
PASS TO SOUTHERN NEW ENGLAND FRIDAY NIGHT INTO SATURDAY. AHEAD OF
ARTHUR...SOUTHWESTERLY WINDS WILL BRING TROPICAL MOISTURE UP INTO
THE REGION...INCREASING PWATS TO AROUND 2 INCHES THURSDAY NIGHT AND
LINGERING ACROSS THE EASTERN ZONES INTO FRIDAY.  AS THE COLD FRONT
APPROACHES SOUTHERN NEW ENGLAND...EXPECT SHOWERS AND THUNDERSTORMS
TO DEVELOP THURSDAY NIGHT.  THESE STORMS WILL RESULT IN HEAVY RAIN.

THERE ARE INDICATIONS THAT THE APPROACHING MID LEVEL TROUGH
AND COLD FRONT COULD INTERACT WITH THE TROPICAL MOISTURE STREAMING
NORTHWARD FROM THIS TROPICAL SYSTEM...RESULTING IN A PREDECESSOR
RAIN EVENT.  THESE EVENTS ARE VERY POORLY FORECAST BY THE
MODELS...PARTICULARLY WHEN IT COMES TO WHERE THE AXIS OF HEAVY RAIN
SETS UP.  THEREFORE...KNOWING WHETHER THE RAIN WILL OCCUR ACROSS
SOUTHERN NEW ENGLAND OR FARTHER TO THE SOUTH AND WEST IS IMPOSSIBLE
TO SAY.

ALL OF THE ABOVE IS MOST LIKELY TO OCCUR THURSDAY NIGHT AND FRIDAY.
THERE IS STILL POTENTIAL FOR HEAVY RAIN FRIDAY NIGHT INTO SATURDAY.
HOWEVER...THIS WILL DEPEND ENTIRELY ON THE EVENTUAL TRACK OF
TROPICAL STORM ARTHUR.  THE HIGHEST LIKELIHOOD FOR PRECIPITATION
BASED ON THE CURRENT FORECAST TRACK IS ACROSS EASTERN MASSACHUSETTS
AND RHODE ISLAND SO WILL KEEP HIGHEST POPS IN THIS REGION.

SATURDAY AND SUNDAY...HIGH PRESSURE BUILDS INTO SOUTHERN NEW ENGLAND
WITH QUIET...SEASONABLY COOL WEATHER EXPECTED.

MONDAY AND TUESDAY...EXPECT INCREASING HEAT AND HUMIDITY AS
SOUTHWESTERLY SURFACE WINDS RETURN.  THERE IS POTENTIAL FOR SHOWERS
AND THUNDERSTORMS TUESDAY.

&&

.AVIATION /14Z WEDNESDAY THROUGH SUNDAY/...
FORECASTER CONFIDENCE LEVELS...

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

THIS AFTERNOON...MODERATE CONFIDENCE. VFR...PATCHES OF MVFR/IFR
CIGS ALONG THE SOUTH COAST EARLY. SW WIND GUSTS TO 20-25 KT S
COAST AND CAPE COD. SCATTERED SHOWERS/TSTMS WILL DEVELOP
ALONG/WEST OF A MHT-ORH- IJD LINE...WITH IFR CIGS/VSBYS IN ANY
TSTMS. HEAVY DOWNPOURS IN ANY TSTMS. TSTMS COULD SPREAD EAST OF
MHT-ORH LATE THIS AFTERNOON.

TONIGHT...MODERATE CONFIDENCE. AREAS OF MVFR/IFR AS STRATUS AND
PATCHY FOG REDEVELOPS. CHC SHOWERS/TSTMS.

THURSDAY...MODERATE CONFIDENCE. MORNING MVFR/IFR IMPROVING TO
VFR...BUT SHOWERS/TSTMS EXPECTED TO DEVELOP WITH MVFR/IFR
CIGS/VSBYS IN ANY TSTMS. HEAVY DOWNPOURS IN ANY TSTMS.

KBOS TAF...MODERATE CONFIDENCE IN TAF. THERE IS A LOW PROB OF IFR
STRATUS LATE TONIGHT.

KBDL TAF...MODERATE CONFIDENCE IN TAF. CHANCE OF TSTMS THIS
AFTERNOON WITH BRIEF MVFR/IFR CIGS/VSBYS. IFR STRATUS POSSIBLE
LATE TONIGHT.

OUTLOOK...THURSDAY NIGHT THROUGH SATURDAY...

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

SATURDAY AND SUNDAY...MODERATE CONFIDENCE. MAINLY VFR.

&&

.MARINE...
FORECASTER CONFIDENCE LEVELS...

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

TONIGHT THROUGH THURSDAY...HIGH CONFIDENCE.

EXPECT MAINLY SW WINDS 10-20 KT THROUGH THE PERIOD BUT CANT RULE
OUT A FEW HIGHER GUSTS APPROACHING SCA OVER NEARSHORE WATERS. 5 FT
SEAS OVER THE OUTER WATERS WILL GRADUALLY SUBSIDE TONIGHT BUT
LIKELY INCREASE AGAIN THURSDAY. SCA FOR HAZARDOUS SEAS CONTINUES.
AREAS OF FOG MAY REDUCE VSBYS TONIGHT. SCT SHOWERS/TSTMS EXPECTED
THU.

OUTLOOK...THURSDAY NIGHT THROUGH SUNDAY...

THURSDAY NIGHT AND FRIDAY...MODERATE CONFIDENCE. PERSISTENT LONG
SOUTH TO SOUTHWEST FETCH SHOULD YIELD SCA SEAS...BETWEEN 3 AND 6
FT...ACROSS MOST OF THE OUTER WATERS.  SCA HEADLINES WILL LIKELY BE
NEEDED FOR THE OUTER-WATERS. THERE IS A RISK OF FOG...PARTICULARLY
DURING THE LATE NIGHT/EARLY MORNING HOURS WITH DEEP LOW LEVEL
MOISTURE IN PLACE. IN ADDITION...HEAVY RAIN IS POSSIBLE AT TIMES
MAINLY ON FRIDAY.

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 COULD HAVE A
SIGNIFICANT IMPACT ON THE MARINE COMMUNITY.  WINDS AND SEAS DIMINISH
SLOWLY SATURDAY AFTERNOON AS ARTHUR MOVES AWAY FROM THE REGION.

SATURDAY NIGHT AND SUNDAY...MODERATE CONFIDENCE.  QUIET BOATING
WEATHER.  LOW PROBABILITY OF 5 FOOT SEAS ON THE OUTER WATERS LATE
SUNDAY.

&&

.HYDROLOGY...
THERE IS THE POTENTIAL FOR SHOWERS AND THUNDERSTORMS PRODUCING
HEAVY RAINFALL FROM THURSDAY INTO FRIDAY NIGHT. THERE IS 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.

&&

.BOX WATCHES/WARNINGS/ADVISORIES...
CT...NONE.
