Severe Thunderstorm Warning 243, NWS Boston/Norton, MA

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
506 PM EDT SUN AUG 10 2008

.SYNOPSIS...
AN UPPER LEVEL LOW OVER SOUTHERN ONTARIO WILL CONTINUE TO PRODUCE
ROUNDS OF SHOWERS AND THUNDERSTORMS THROUGH EARLY TUESDAY AS IT
TRACKS SOUTH OF NEW ENGLAND. DRIER CONDITIONS SHOULD RETURN FOR MID
TO LATE WEEK.

&&

.NEAR TERM /UNTIL 9 PM THIS EVENING/...
AXIS OF HIGHEST ML CAPE /NEAR 1000/ REMAINS JUST W OF REGION...FROM
EASTERN NY INTO MID ATLANTIC REGION. SO FAR STORMS HAVE BEEN FOCUSED
NEAR HIGHER TERRAIN...ESPECIALLY NEAR BERKSHIRES AND MONADNOCKS...
WITH A FEW ALSO TRYING TO FORM NEAR SEA BREEZE BOUNDARIES ALONG BOTH
E AND E COASTS. POINT LAPS SOUNDINGS STILL SHOW A WEAK CAP IN PLACE
NEAR 700 MB WHICH PARTIALLY EXPLAINS WHY STORMS HAVE HAD A HARD TIME
STRENGTHENING THIS FAR E.

TREND SHOULD BE FOR STORMS TO REMAIN MOST NUMEROUS ACROSS INTERIOR
THROUGH THIS EVENING. STILL HAVE POTENTIAL FOR ISOLATED SEVERE STORMS
WITH LARGE HAIL...THOUGH MANY OF THE STRONGER STORMS WILL BE CAPABLE
OF PRODUCING PEA SIZED HAIL. DEBRIS CLOUDS STREAMING UP FROM MID
ATLANTIC MAY EVENTUALLY SUPPRESS CONVECTION IN OUR REGION LATE THIS
AFTERNOON...ESPECIALLY ACROSS CT AND WESTERN MA.

&&

.SHORT TERM /9 PM THIS EVENING THROUGH 6 PM MONDAY/...
ONCE CONVECTION DIMINISHED THIS EVENING...WE SHOULD HAVE ANOTHER
ROUND TO CONTEND WITH OVERNIGHT. 12Z GFS REMAINS AGGRESSIVE IN
BRINGING CONVECTIVE COMPLEX UP THROUGH CT/RI/SE MA FROM MID ATLANTIC
STATES AS SHORT WAVE ROTATES AROUND UPPER LOW. THIS IS NOT COMPLETELY
SUPPORTED BY 09Z SREFS OR 12Z NAM...BUT BASED UPON LATEST RADAR
TRENDS WE WOULD THINK AT VERY LEAST AN AREA OF SHOWERS/EMBEDDED
THUNDER WILL WORK ITS WAY INTO MUCH OF REGION TONIGHT. THERE IS
PLENTY OF INSTABILITY ALOFT WITH ML CAPE NEAR 1000 AND INCREASING LOW
LEVEL SHEAR TO SUPPORT ISOLATED SEVERE STORMS...ESPECIALLY OVER SE
NEW ENGLAND. WE WILL BRING LIKELY POPS INTO MOST OF REGION LATER THIS
EVENING AND MENTION ISOLATED SEVERE POTENTIAL IN HWO.

ONCE THIS AREA OF CONVECTION HEADS OFFSHORE MON MORNING...WE GET INTO
PERSISTENT E/NE FLOW WHICH SHOULD MAINTAIN CLOUDINESS THROUGH DAY.
DESPITE WHAT LOOKS TO BE A STABILIZING AIRMASS AT SURFACE...APPROACH
OF UPPER LOW AND ITS ASSOCIATED COLD POOL ALOFT SHOULD BE ABLE TO
PRODUCE ANOTHER ROUND OF SHOWERS/STORMS MON AFTERNOON AS ML CAPES
INCREASE TO AROUND 1000 OR SO. ISOLATED SEVERE STORMS CAN ONCE AGAIN
BE EXPECTED WITH HAIL BEING MAIN THREAT.

&&

.LONG TERM /MONDAY NIGHT THROUGH SUNDAY/...
ANOMALOUSLY STRONG UPPER TROF WILL TRAVERSE THE REGION MONDAY NIGHT.
AND FINALLY BE ON ITS WAY EASTWARD TOWARD NOVA SCOTIA BY TUE AFTERNOON.
WILL KEEP LIKELY POPS FOR SHOWERS AND POSSIBLE TSTMS IN THE NORTHERN
AND EASTERN PORTIONS OF THE FORECAST AREA EARLY MON NIGHT...TAPERING
DOWN TO A CHANCE BY MIDNIGHT.

A FLATTER FLOW ENSUES ON TUE...BUT CYCLONIC FLOW AND INSTABILITY WILL
ALLOW FOR A SMALL CHANCE OF SHOWERS AND ISOLATED THUNDERSTORMS...MAINLY
IN THE AFTERNOON.

TEMPERATURES AT 500 MB WARM TO A WHOPPING -12C TO -13C WED. ALTHOUGH
THIS IS MORE STABLE THAN IT HAS BEEN...STILL CANNOT RULE OUT A SLIGHT
CHANCE OF A DIURNAL SHOWER OR ISOLATED TSTM.

THU AND FRI CONTINUE TO LOOK MAINLY DRY WITH TEMPERATURES REACHING
THE LOWER 80S. GFS AND ECMWF CONTINUE TO HINT AT SMALL CHANCES OF SHOWERS
ALONG THE SOUTHERN COAST OF NEW ENGLAND AND LONG ISLAND. HAVE KEPT
SLIGHT CHANCE POPS WHICH APPEAR IN THE GRID BUT NOT THE ZFP.

EXPECT HIGH PRESSURE FROM NEW ENGLAND EASTWARD OUT SEA SAT PROVIDING
A MOSTLY SUNNY DAY WITH SEASONABLY WARM TEMPERATURES. RETURN FLOW
AROUND THE HIGH PROMISES TO BRING MORE MOISTURE LATE SUNDAY WITH A
CHANCE OF AFTERNOON SHOWERS AND THUNDERSTORMS...MAINLY IN WESTERN
SECTIONS. AFTER THAT...A BERMUDA HIGH SETS UP WITH LOW PRESSURE TO
OUR WEST...KEEPING US IN A WARM AND MOIST FLOW.

&&

.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
SCATTERED TSTMS WILL BRING LOCAL IFR THROUGH 23Z...MAINLY KBAF/KBDL
AND KORH TERMINAL AREAS. STORMS WILL BE MOST NUMEROUS FROM BERKSHIRES
TO MONADNOCKS AND WORCESTER HILLS WITH SMALL HAIL IN STRONGER STORMS.
ISOLATED SEVERE STORMS POSSIBLE WITH LARGE HAIL.

KBOS TAF COLLABORATED WITH CWSU ZBW. EXPECT TSTMS TO REMAIN W OF
TERMINAL AREA THROUGH THIS EVENING...ALTHOUGH ISOLD TSTMS POSSIBLE
W/NW.

TONIGHT...SHOWERS MOVE INTO REGION 02Z CT VALLEY AND 08Z COAST WITH
MVFR CONDITIONS. ISOLATED TSTMS POSSIBLE DUE TO INSTABILITY ALOFT.
POTENTIAL FOR IFR ALONG S COAST BUT NOT ENOUGH CONFIDENCE TO INCLUDE
IN KFMH/KHYA/KACK TAFS.

MON...MVFR CEILINGS IN SHOWERS AND SCATTERED TSTMS. IFR POSSIBLE S
COASTAL TERMINALS ESPECIALLY MON AFTERNOON.

OUTLOOK...MONDAY NIGHT THROUGH FRIDAY...

MVFR TO IFR CONDITIONS IN SHOWERS AND ISOLATED TSTMS ARE EXPECTED
MONDAY NIGHT FOR MUCH OF SOUTHERN NEW ENGLAND. IMPROVEMENT IS
FORECASTED TUE...BUT PERIODS OF MVFR CONDITIONS ARE LIKELY. WED
THROUGH FRI...MAINLY VFR EXPECTED.

&&

.MARINE...
POTENTIAL FOR SCATTERED STRONG STORMS TONIGHT INTO MON MORNING AS
ACTIVITY OVER MID ATLANTIC REGION TRACKS INTO SE NEW ENGLAND...WITH
WIND GUSTS TO 40KT POSSIBLE. ADDITIONAL STORMS POSSIBLE MON
AFTERNOON.

OTHERWISE WINDS AND SEAS BELOW SCA INTO MON. INCREASING SE FLOW MAY
BRING SEAS CLOSE TO 5 FT ON OUTER SE WATERS MON AFTERNOON.

OUTLOOK...MONDAY NIGHT THROUGH FRIDAY... NEAR SMALL CRAFT ADVISORY
CONDITIONS ARE POSSIBLE...ESPECIALLY ON THE OUTER WATERS...MON NIGHT
INTO EARLY TUE AS LOW PRESSURE SLOWLY MOVES AWAY FROM THE REGION. FOR
NOW...AM EXPECTING WIND GUSTS TO 20 KNOTS WITH 4 FOOT SEAS...JUST
BELOW THE CRITERIA OF 25 KNOTS AND 5 FOOT SEAS.

A STRONG STORM SYSTEM WILL MOVE FROM THE SOUTHERN STATES TO THE
CAROLINAS THEN PASSING OUT TO SEA WELL TO THE SOUTHEAST OF NANTUCKET
LATE WED NIGHT AND THU. THIS SHOULD LITTLE IMPACT ON OUR FORECAST BUT
SEAS ARE FORECAST TO BUILD TO NEAR 7 FT IN THE WATERS NEAR GEORGES
BANK.

OTHERWISE...RATHER TRANQUIL CONDITIONS ARE EXPECTED ON THE COASTAL
WATERS WED AND THU. SEAS WILL BUILD TO 4 OR PERHAPS 5 FEET AS
SOUTHERLY WINDS GUST TO 20 KNOTS ON FRI...CLOSE TO SMALL CRAFT
ADVISORY THRESHOLDS.

&&

.HYDROLOGY...
POTENTIAL FOR LOCALLY HEAVY RAINFALL TONIGHT INTO MON AS SHOWERS AND
SCATTERED THUNDERSTORMS MOVE THROUGH REGION. MOST AREAS SHOULD
RECEIVE UP TO ONE INCH...WITH AS MUCH AS 2 INCHES LOCALLY.

ALTHOUGH PRECIPITABLE WATER VALUES ARE NOT ESPECIALLY HIGH...MAINLY
AROUND 1.75 INCHES...LARGER SCALE PATTERN OF ANOMALOUS CLOSED LOW
IS FAVORABLE FOR AN INCREASED LOCALIZED FLASH FLOOD POTENTIAL MON
INTO TUE. MAIN AREA OF CONCERN IS ALONG AND N OF MASS PIKE...WHERE
ANTECEDENT CONDITIONS ARE ESPECIALLY MOIST. ANOTHER 1 TO 2 INCHES OF
RAIN MAY FALL LOCALLY MON NIGHT AND TUE.

MINOR URBAN AND POOR DRAINAGE FLOODING CAN BE EXPECTED IN AREAS OF
HEAVIER RAIN. FLOOD WATCHES MAY BE NEEDED IN LATER FORECASTS IF THE
POTENTIAL FOR HEAVIER RAIN INCREASES OVER A LARGE AREA.
