AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
237 PM EDT WED JUL 21 2010

.SYNOPSIS...
AN APPROACHING COLD FRONT WILL BRING THE POSSIBILITY OF SEVERE
THUNDERSTORMS THROUGH EARLY TONIGHT. HOT AND HUMID WEATHER WILL
RETURN BY SATURDAY...BEFORE ANOTHER COLD FRONT BRINGS A FEW
THUNDERSTORMS SATURDAY AFTERNOON/NIGHT. RELIEF FROM THE HEAT AND
HUMIDITY SHOULD ARRIVE EARLY NEXT WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
SEVERE THUNDERSTORM WATCH 507 WHICH IS IN EFFECT UNTIL 8 PM HAS
BEEN EXPANDED INTO RI AND EASTERN MA. WE EXCLUDED CAPE COD...MARTHAS
VINEYARD AND NANTUCKET WHERE OUR CONFIDENCE IS LOWER FOR SEVERE
WEATHER TO OCCUR. SOUTHERLY FLOW SHOULD KEEP AIRMASS MORE STABLE...
ALTHOUGH ELEVATED STORMS ARE CERTAINLY POSSIBLE.

MAX INSTABILITY AXIS EXTENDS ACROSS CT...RI AND INTERIOR SE MA.
0-6KM SHEAR HAS ALSO INCREASED THIS AFTERNOON BUT HIGHER VALUES
/40KT/ AND BETTER MID LEVEL LAPSE RATES ARE STILL BACK ACROSS
CENTRAL AND EASTERN NY. INTERESTING TO NOTE ACTIVITY SO FAR HAS
BEEN IN FORM OF DISCRETE CELLS AS OPPOSED TO ORGANIZED LINE
SEGMENTS...AND LATEST HRRR/COSPA INDICATE THIS WILL BE TREND AS
ACTIVITY BECOMES MORE WIDESPREAD IN SOUTHERN NEW ENGLAND THIS
EVENING. MAIN HAZARDS CONTINUE TO BE DAMAGING WINDS AND LARGE HAIL
BUT ANY RIGHT MOVING CELLS WOULD CERTAINLY HAVE TORNADIC
POTENTIAL. LOW CONFIDENCE ON THAT OCCURRING HOWEVER.

INCREASED POPS TO LIKELY THROUGH EARLY TONIGHT...THEN EXPECT
ACTIVITY TO SUBSIDE AFTER MIDNIGHT AS COLD FRONT PUSHES THROUGH.
MAIN WINDOW FOR STORMS IS 4-7 PM FROM KEENE TO HARTFORD AND 6-10
PM MANCHESTER TO BOSTON AND PROVIDENCE. PATCHY FOG EXPECTED
OVERNIGHT...ESPECIALLY ALONG S COAST AND WHERE ANY RAINFALL
OCCURS.

&&

.SHORT TERM /THURSDAY THROUGH THURSDAY NIGHT/...
DRIER AIR ARRIVES THU AND THU NIGHT AS HIGH PRESSURE BUILDS INTO
REGION.

FAIRLY DEEP MIXING LAYER EXPECTED THU PER MODEL SOUNDINGS SO WE
CONTINUE TO INDICATE 25-30 MPH GUSTS...ESPECIALLY INLAND. HIGHS
SHOULD REACH WELL INTO 80S WITH DOWNSLOPING W/NW FLOW.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
HIGHLIGHTS...
*A ROUND OF SCATTERED RAIN SHOWERS POSSIBLE FRIDAY AFTERNOON/NIGHT
*VERY WARM/HUMID WEATHER RETURNS BY SATURDAY WITH THE CHANCE OF A
FEW SHOWERS/STORMS IN THE AFTERNOON OR NIGHT
*RELIEF FROM THE HEAT/HUMIDITY EARLY NEXT WEEK WITH MAINLY DRY
WEATHER

DETAILS...

THURSDAY NIGHT...
A WEAK RIDGE OF HIGH PRESSURE WILL BRING A DRY AND SEASONABLE
NIGHT.  SKIES WILL START OFF MOSTLY CLEAR...BUT WEST TO NORTHWEST
FLOW ALOFT SHOULD BRING AN INCREASE IN AT LEAST SOME HIGH CLOUDS
FROM THE WEST AFTER MIDNIGHT.  LOW TEMPERATURES SHOULD MAINLY BE IN
THE 60S...WITH SOME UPPER 50S EXPECTED ACROSS PORTIONS OF SOUTHWEST
NH/NORTHWEST MA.  WE MAY SEE A TOUCH OF PATCHY GROUND FOG DEVELOP IN
THE TYPICALLY PRONE LOCATIONS LATE.

FRIDAY AND FRIDAY NIGHT...
FORECAST CONFIDENCE IS WELL BELOW NORMAL OVER THIS TIME.  A WARM
FRONT WILL EXTEND SOUTHEASTWARD ACROSS SOUTHERN NEW ENGLAND FROM A
LOW PRESSURE SYSTEM OVER THE GREAT LAKES.  THIS PATTERN IS FAVORABLE
FOR MCS DEVELOPMENT ACROSS THE LAKES WITH THE COMPLEX LIKELY
PROPAGATING EAST SOUTHEASTWARD.  AS IS USUALLY THE CASE WITH THESE
MCS/S...THE MODELS ARE ALL OVER THE PLACE WITH THEIR TRACK AND
TIMING.

CONFIDENCE IN WHERE THIS MCS WILL GO AND HOW EXACTLY IT WILL AFFECT
OUR WEATHER IS VERY LOW.  HOWEVER...ALL THE MODELS SHOW THE BEST
INSTABILITY WILL BE LYING TO OUR SOUTH AND WEST.  THESE COMPLEX/S
OFTEN BEND TOWARDS THE HIGHER INSTABILITY AXIS.  THEREFORE...OUR
BEST ESTIMATE IS THAT WE WILL BE ON THE NORTHEAST FRINGE OF THE
COMPLEX WITH THE HEAVIEST ACTION PROBABLY PASSING TO OUR SOUTH AND
WEST.  HOWEVER...STILL THINK WE MAY SEE SOME SHOWERS WITH THE WARM
FRONTAL PASSAGE SOMETIME FRIDAY AFTERNOON AND/OR NIGHT.
THEREFORE...WILL RUN WITH CHANCE POPS FOR THE POTENTIAL OF A PERIOD
OF SCATTERED RAIN SHOWERS WITH THE HIGHEST IN OUR WESTERN/SOUTHERN
ZONES.  FOR NOW WE DID NOT INCLUDE THUNDER AS INSTABILITY LOOKS
RATHER LIMITED IN SOUTHERN NEW ENGLAND...BUT AND ISOLATED RUMBLE OR
TWO IS CERTAINLY NOT OUT OF THE QUESTION.

SATURDAY AND SATURDAY NIGHT...
THE WARM FRONT WILL LIFT NORTH OF SOUTHERN NEW ENGLAND.  THIS WILL
BRING A RETURN TO VERY WARM WEATHER ALONG WITH HIGH HUMIDITY
VALUES.  A GOOD PORTION OF THE DAY WILL BE DRY...BUT AS THE COLD
FRONT APPROACHES ITS POSSIBLE THAT WE SEE SOME SCATTERED
SHOWERS/THUNDERSTORMS SOMETIME DURING THE AFTERNOON OR NIGHT.
CONFIDENCE ON THIS IS LOW BECAUSE OF A STRONG MID LEVEL CAP WHICH IF
IT HANGS TOUGH WOULD LIMIT CONVECTIVE POTENTIAL.

SUNDAY THROUGH TUESDAY...
THE LONG RANGE MODELS ARE IN FAIRLY GOOD AGREEMENT THAT WE WILL
FINALLY UNDERGO A PATTERN CHANGE.  AN UPPER LEVEL TROUGH DEVELOPS TO
OUR NORTHEAST WHICH SHOULD KEEP OUR WEATHER MAINLY DRY WITH
SEASONABLE TEMPERATURES.  HUMIDITY VALUES WILL BE LOWER AND MUCH
MORE COMFORTABLE THAN WHAT WE HAVE EXPERIENCED FOR MUCH OF THIS
MONTH.

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
MEDIUM CONFIDENCE ON IFR/LIFR RETURNING TO S COAST AROUND SUNSET.
TAFS MAY BE A COUPLE OF HOURS EARLY ON TIMING. TSTMS WITH MVFR/IFR
EXPECTED TO BECOME NUMEROUS BAF/BDL 21Z-23Z AND PVD/BOS/MHT
00Z-02Z AS ACTIVITY ACROSS EASTERN NY HEADS INTO SOUTHERN NEW
ENGLAND. POTENTIAL FOR DAMAGING WINDS AND LARGE HAIL DURING THIS
TIME FRAME.

SHOULD SEE IMPROVEMENT TO VFR AFTER 06Z EXCEPT FOR FMH HYA ACK
WHERE FOG WILL PERSIST UNTIL DAYBREAK THU.

THU AND THU NIGHT...HIGH CONFIDENCE VFR. W/NW WIND GUSTS TO 25KT
12Z- 22Z. PATCHY FOG POSSIBLE LATE THU NIGHT.

KBOS TERMINAL...TAF COORDINATED WITH CWSU ZBW. HIGH CONFIDENCE ON
SEA BREEZE SUBSIDING 23Z-01Z. TSRA MOST LIKELY 00Z-02Z BUT ISOLD
TSTMS COULD AFFECT TERMINAL AS EARLY AS 21Z.

OUTLOOK...FRIDAY THROUGH MONDAY...

FRIDAY THROUGH SATURDAY NIGHT...A PERIOD OF TWO OF MVFR-IFR
CONDITIONS ARE POSSIBLE IN SCATTERED SHOWERS/STORMS AND ALSO
PATCHY LOW CLOUDS/FOG DURING THE OVERNIGHT/EARLY MORNING HOURS.

SUNDAY AND MONDAY...MAINLY VFR CONDITIONS EXPECTED.

&&

.MARINE...
WINDS AND SEAS EXPECTED TO REMAIN BELOW SCA THROUGH THU NIGHT.
SOUTHERLY SWELL COULD BRING 5 FT SEAS BACK INTO S COASTAL WATERS
THU AND THU EVENING...BUT CONFIDENCE IS NOT HIGH ENOUGH TO ISSUE
SCA AT THIS TIME...ESPECIALLY GIVEN W/NW FLOW.

OUTLOOK...FRIDAY THROUGH SUNDAY...

THURSDAY NIGHT...A WEAK RIDGE OF HIGH PRESSURE OVER THE WATERS
SHOULD ALLOW SOUTHERLY SWELL TO DIMINISH BELOW SCA THRESHOLDS ACROSS
THE SOUTHERN OUTER-WATERS TOWARD DAYBREAK FRIDAY MORNING.

FRIDAY...THE WEAK RIDGE OF HIGH PRESSURE SHOULD KEEP WINDS AND SEAS
BELOW SCA THRESHOLDS.

SATURDAY INTO SUNDAY...INCREASING SOUTHWEST FLOW AHEAD OF AN
APPROACHING COLD FRONT MAY BRING A RETURN OF 4 TO 6 FOOT SEAS ACROSS
THE SOUTHERN OUTER-WATERS LATE SATURDAY AFTERNOON LINGERING INTO
SUNDAY.  AN INVERSION WILL LIKELY KEEP WIND GUSTS BELOW CRITERIA
ACROSS THE OPEN WATERS.
