AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
431 AM EDT TUE JUL 6 2010
.SYNOPSIS...
EXCESSIVE HEAT TODAY WILL GIVE WAY TO A SOMEWHAT COOLER BUT MORE
HUMID AIR MASS FOR MID TO LATE WEEK AS WINDS GRADUALLY TURN
ONSHORE. TEMPERATURES WILL STILL REMAIN ABOVE NORMAL THROUGH
FRIDAY HOWEVER. THE PATTERN LOOKS TO BREAK DOWN A BIT OVER THE
WEEKEND AS A COLD FRONT SLOWLY CROSSES THE REGION WITH SHOWERS AND
THUNDERSTORMS.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
DANGEROUS HEAT INDICES OF 100-104 DEGREES EXPECTED FOR SEVERAL
HOURS THIS AFTERNOON AND EARLY EVENING. HAVE SLIGHTLY EXPANDED
HEAT ADVISORY...MAINLY FOR AREAS AWAY FROM THE IMMEDIATE COAST AND
HIGHER TERRAIN. DECIDED TO INCLUDE SUFFOLK COUNTY...EVEN WITH A
SEA BREEZE EXPECTED LATER TODAY FOR AREAS WELL AWAY FROM THE
COAST AS HEAT INDICES WILL BE CLOSE TO 100 DEGREES.
MAV GUIDANCE HANDLED TEMPERATURES WITH THE SEA BREEZE MONDAY MUCH
BETTER THAN THE MET GUIDANCE...WHICH WAS TOO HIGH. WITH SIMILAR
SITUATION TODAY...STAYED WITH THE MAV FOR THE IMMEDIATE EAST
COAST. FARTHER INLAND...GUIDANCE IS VERY CLOSE SO WENT WITH THE
CONSENSUS.
MID-LEVEL CLOUDS WILL BE EXITING TO THE EAST THIS MORNING.
MOISTURE PROFILES INDICATE SOME LOW-LEVEL MOISTURE MAY LEAD TO
SCT-BKN CUMULUS CLOUDS ACROSS EASTERN NEW ENG. THE MAIN
UNCERTAINTY FOR THIS AFTERNOON LIES IN THE POTENTIAL FOR ANY
THUNDERSTORMS. AIR MASS DOES DESTABILIZE AS LOW-LEVEL MOISTURE
INCREASES...AND SOUNDINGS LOOK TO BE QUITE TROPICAL.
BUT WARM TEMPS ALOFT MAY PROVIDE A CAP AND NAM AND GFS SOUNDINGS
SHOW THIS WELL WITH CAP AT 12-13 KFT. THIS CAP COULD BE BROKEN IF
DEW POINTS GET INTO THE LOWER 70S. BEST CHC OF AN ISOLATED
THUNDERSTORM WILL BE ACROSS EASTERN NEW ENGLAND ALONG THE SEA
BREEZE BOUNDARY...WHERE CONVERGENCE AND MOISTURE POOLING WILL BE
GREATEST. MAINTAINED A MENTION OF THESE ISOLATED THUNDERSTORMS.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/...
TONIGHT...AN OCEAN LOW BEGINS TO RETROGRADE TOWARD THE MID
ATLANTIC COAST...WITH A LOW PROBABILITY OF A FEW SHOWERS NEAR THE
SOUTH COAST AND CAPE COD. OTHERWISE MID-LEVEL RIDGING REMAINS IN
PLACE. UNCOMFORTABLY WARM AND HUMID NIGHT EXPECTED WITH DEW
POINTS NEAR 70. MINS 65 TO 70 EXCEPT LOW/MID 70S IN THE URBAN
CENTERS. PATCHY LATE NIGHT FOG AS ONSHORE FLOW MAINTAINS ITSELF.
SKY COVER WILL BE TRICKY LATE TONIGHT INTO WEDNESDAY. EASTERLY
FLOW COULD LEAD TO THE FORMATION OF MARINE STRATUS...WHICH COULD
REALLY CHANGE TEMPERATURE FORECAST LATE TONIGHT INTO WEDNESDAY.
THINK THE NAM IS OVERDOING ITS BOUNDARY LAYER MOISTURE...SO WHILE
HAVE SOME CLOUDS IN THE FORECAST NOW...DID NOT GO WITH AN OVERCAST
MOST OF WEDNESDAY MORNING. THIS WILL NEED TO BE WATCHED.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
BLOCKY PATTERN ALONG THE EAST COAST WILL RESULT IN A STAGNANT
PATTERN THROUGH THE END OF THE WEEK. THIS WILL MEAN WARMER THAN
NORMAL TEMPERATURES AND MAINLY RAIN-FREE WEATHER. HUMIDITY LEVELS
WILL GRADUALLY COME UP.
ANY ISOLD SHOWERS OR THUNDERSTORMS IN THE WEST OWING TO WEAK
SYNOPTIC SCALE SFC CONVERGENCE OR DIFFERENTIAL HEATING SHOULD
DISSIPATE EARLY WEDNESDAY EVENING...ALLOWING FOR A DRY NIGHT.
RIDGING WILL CONTINUE TO HOLD FIRM THURSDAY AND FRIDAY. WHILE AN
ISOLD POP-UP SHOWER OR THUNDERSTORM IS POSSIBLE...MOST LOCATIONS
WILL REMAIN DRY. WE EXPECT MAXES AROUND 90 AWAY FROM THE COAST.
BLOCKY PATTERN BEGINS TO BREAK DOWN FRIDAY NIGHT AS SHORT WAVE
TROUGH OVER ONTARIO ACTS AS A KICKER AS IT PROGRESSES EASTWARD.
THIS WILL ALLOW A COLD FRONTAL BOUNDARY TO SAG CLOSER TO SOUTHERN
NEW ENGLAND...AND ALONG WITH IT INCREASING CHANCES FOR SHOWERS AND
THUNDERSTORMS FRIDAY NIGHT THROUGH SATURDAY /THE FRONT WILL BE
SLOW-MOVING/. A SURFACE WAVE MAY DEVELOP ALONG THIS FRONT TO OUR
SOUTH SATURDAY NIGHT AND THIS MAY ALLOW FOR SHOWERY WEATHER TO
LINGER INTO SUNDAY. CONFIDENCE IS LOW ON THIS THOUGH...IN FACT WE
ARE NOT QUITE SURE HOW FAR SOUTH THE COLD FRONT WILL PROGRESS IN
THE FIRST PLACE.
FAIR WEATHER IS EXPECTED TO RETURN FOR LATE SUNDAY AND MONDAY.
&&
.AVIATION /09Z TUESDAY THROUGH SATURDAY/...
TODAY...MODERATE TO HIGH CONFIDENCE VFR. AREAS OF HAZE MAY REDUCE
VISIBILITIES TO MVFR AT TIMES. COASTAL SEA BREEZES SHOULD DEVELOP
AGAIN...BUT MAY BE DELAYED UNTIL EARLY OR MID AFTERNOON. SCT-BKN
CUMULUS DEVELOPING THIS AFTERNOON...MAINLY ACROSS THE COASTAL
PLAIN. THERE IS A LOW PROB FOR AN ISOLATED TSTM DEVELOPING NEAR THE
SEA BREEZE BOUNDARY THIS AFTERNOON.
KBOS...SEA BREEZE EXPECTED TO DEVELOP BY AFTERNOON. ONSHORE FLOW
EXPECTED TO MAINTAIN ITSELF OVERNIGHT...BUT BECOME LIGHTER. THIS
COULD LEAD TO MARINE STRATUS LATE TONIGHT INTO WEDNESDAY.
CONFIDENCE IS NOT YET HIGH ENOUGH TO PLACE THIS STRATUS IN THE
TAF.
TONIGHT AND WEDNESDAY...MODERATE TO HIGH CONFIDENCE FOR VFR. SCT
MVFR CEILINGS AND VSBYS WITH AFTERNOON SCT SHRA/TSRA POSSIBLE
ACROSS THE INTERIOR FROM KBDL-KORH-KMHT AND POINTS W.
OUTLOOK...WEDNESDAY NIGHT THROUGH SATURDAY...
MAINLY VFR CONDITIONS ARE EXPECTED WEDNESDAY NIGHT THROUGH FRIDAY.
HOWEVER...THIS COMES WITH ONLY MEDIUM CONFIDENCE AS MOISTENING
SOUTHERLY FLOW MAY AID IN THE DEVELOPMENT OF NIGHTTIME/MORNING
STRATUS AND FOG WHICH WILL PROBABLY LEAD TO IFR
CONDITIONS...MAINLY ON THE COAST...BUT COULD OCCUR INLAND AS WELL.
A COLD FRONT WILL APPROACH FRIDAY NIGHT AND SATURDAY...WITH AT
LEAST SCATTERED SHOWERS AND TSTMS OCCURRING DURING THIS TIME.
LOCALLY LOWER CONDITIONS ARE EXPECTED WITH THIS ACTIVITY...ALONG
WITH THE PROBABILITY OF FOG AND STRATUS.
&&
.MARINE...
WINDS AND SEAS WILL REMAIN BELOW SMALL CRAFT ADVISORY LEVELS
THROUGH WEDNESDAY.
OUTLOOK...WEDNESDAY NIGHT THROUGH SATURDAY....
WEDNESDAY NIGHT AND THURSDAY...WINDS AND SEAS EXPECTED TO REMAIN
BELOW SCA CRITERIA WITH WEAK PRESSURE PATTERN IN PLACE.
FRIDAY AND SATURDAY...SSE SWELL MAY APPROACH 5 FT ACROSS THE
SOUTHERN COASTAL WATERS. OTHERWISE...WINDS REMAIN BELOW SCA.
