AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
1129 AM EDT WED AUG 5 2009

.SYNOPSIS...
A COOL FRONT CROSSING OUR AREA THIS AFTERNOON MAY STALL ACROSS THE
WATERS LATE TONIGHT BEFORE EVENTUALLY MOVING OFFSHORE LATE THU.
DRIER AND COOLER AIR WITH A HIGH PRESSURE MOVES INTO THE MID
ATLANTIC STATES FRI. THIS HIGH PRESSURE WILL BRING SEASONABLY WARM
AND DRY CONDITIONS THROUGH SAT. HEAT AND HUMIDITY IS EXPECTED TO
RETURN FOR A TIME EARLY NEXT WEEK AS A WARM FRONT LIFTS NORTH OF OUR
AREA.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
STRATUS AND PATCHY FOG CONTINUES TO DISSIPATE ACROSS CAPE COD AND THE
ISLANDS. EXPECTING PLENTY OF SUNSHINE THIS AFTERNOON. 05/12Z
SOUNDINGS INDICATE SURFACE-BASED CAPE OF 1500-2000 J/KG POSSIBLE WITH
TEMPERATURES IN THE LOWER 80S. WIND SHEAR IS A BIT ON THE WEAK SIDE
FOR ORGANIZED CONVECTION ACROSS SOUTHERN NEW ENGLAND...BUT GETS
STRONGER FARTHER NORTH.

OTHERWISE...ONLY MINOR TWEAKS TO PREVIOUS FORECAST BASED ON LATEST
OBSERVATIONS THIS MORNING.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/...
THE COOL FRONT STALLS IN THE CW LATER TONIGHT AND THEN EDGES OFFSHORE
LATE THU. IN THE STALL PERIOD...A WEAK WAVE OF LOW PRES MAY SLIDE NE
ALONG THE FRONT PRODUCING SHOWERS AND ISO TSTMS...ESPECIALLY SE OF A
BOS-IJD LINE SOMETIME LATER TONIGHT OR THU. MODEL UNCERTAINTY AND
THEREFORE SREF POPS AND GFS MOS TEMPS AND 50 50 NAM/GFS WINDS  WERE
THE BASELINE PREDICTORS. GFS MOSGUIDE FOR SKY. -2SBLI FOR THUNDER.

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
THURSDAY NIGHT...ALL MODELS DEVELOP LOW PRESSURE OFF THE COAST
UNDERNEATH THE RIGHT REAR QUADRANT OF A H25 JET STREAK...ALSO AS A
SHORT WAVE TRACKS ACROSS NEW YORK STATE. THE GFS IS FURTHEST NORTH
WITH THIS AREA OF LOW PRESSURE WHILE THE UKMET/NAM SOLUTIONS ARE
WEAKER AND MORE PROGRESSIVE. PREFER THE UKMET/NAM SOLUTIONS AT THIS
TIME AND THEREFORE ADVERTISED SLIGHT CHANCE TO LOW CHANCE POPS ACROSS
THE CAPE AND ISLANDS.

FRIDAY AND SATURDAY...HIGH PRESSURE PREVAILS OVER THE AREA WITH
SEASONABLY MILD AND DRY CONDITIONS EXPECTED. A SHORT WAVE TRACKING
ALONG THE OLD FRONTAL BOUNDARY SATURDAY SHOULD REMAIN SOUTHWEST
OF THE REGION.

SUNDAY AND SUNDAY NIGHT...A WARM FRONT WILL GRADUALLY APPROACH
THE AREA FROM THE SOUTHWEST. HAVE DECIDED TO TREND MAXIMUM
TEMPERATURES DOWN A BIT DURING SUNDAY GIVEN PREVAILING SOUTH TO
SOUTHEAST BOUNDARY LAYER FLOW IN ADVANCE OF THE FRONT. MAINTAINED LOW
CHANCE POPS ACROSS THE INTERIOR WITH SLIGHT CHANCE POPS ELSEWHERE
SUNDAY NIGHT INTO MONDAY MORNING. CONCENTRATED THE HIGHER POPS WHERE
THE BEST ISENTROPIC LIFT IS POSSIBLE NORTH OF THE WARM FRONT.
GENERALLY FOLLOWED THE 00Z ECMWF/18Z HPC SOLUTIONS. THE GFS HAS HAD
A DIFFICULT TIME PINPOINTING THE WARM FRONT WITH SPURIOUS VORTICITY
CENTERS ARRIVING DUE TO CONVECTIVE FEEDBACK ISSUES SO GENERALLY DID
NOT PUT TOO MUCH CREDENCE INTO THE LATEST 00Z RUN.

MONDAY THROUGH TUESDAY...A BRIEF PERIOD OF HOT AND HUMID WEATHER IS
EXPECTED BEFORE A COLD FRONT APPROACHES FROM CANADA. TEMPERATURES
MAY NEED TO BE RAISED A FEW DEGREES ON MONDAY DEPENDING ON THE
ARRIVAL TIME OF THE HOTTEST AIR. STILL A BIT EARLY TO SPECIFY THE
DETAILS.

IF THE 00Z ECMWF VERIFIES WIDESPREAD 90 TO 95 DEGREE TEMPERATURES
COULD OCCUR AWAY FROM THE SOUTH COAST MONDAY. HIGH HUMIDITY COULD
ALSO BRING NEAR HEAT ADVISORY CRITERIA TO THE REGION THAT DAY. WILL
CONTINUE TO MONITOR. STILL ANOTHER VERY WARM AND HUMID DAY EXPECTED
TUESDAY. GIVEN DECENT AGREEMENT AMONGST THE ENSEMBLES REGARDING
HEIGHT FALLS TUESDAY...INCLUDED A LOW CHANCE POPS FOR SHOWERS AND
THUNDERSTORMS AT THAT TIME.

&&

.AVIATION /15Z WEDNESDAY THROUGH SUNDAY/...
TODAY...IFR ST/FOG MAY LINGER PORTIONS OF CAPE COD AND THE ISLANDS
ALL DAY. MAINLY VFR ELSEWHERE.
