AREA FORECAST DISCUSSION...AVIATION UPDATE
NATIONAL WEATHER SERVICE TAUNTON MA
449 PM EDT SUN JUL 26 2009
.SYNOPSIS...
LOW PRESSURE IN SOUTHEAST CANADA AND HIGH PRESSURE OVER THE WESTERN
ATLANTIC WILL CONTINUE TO CIRCULATE A WARM AND HUMID AIRMASS INTO
SOUTHERN NEW ENGLAND FOR THE UPCOMING WEEK AND PROBABLY INTO NEXT
WEEKEND. WHILE THERE WILL BE MANY PERIODS OF DRY WEATHER SCATTERED
SHOWERS AND THUNDERSTORMS CAN BE EXPECTED...ESPECIALLY TONIGHT AND
MONDAY...THEN AGAIN WEDNESDAY NIGHT INTO THURSDAY.
&&
.NEAR TERM /UNTIL 6 AM MONDAY MORNING/...
SCATTERED THUNDERSTORMS WERE DEVELOPING THIS AFTERNOON WITH 1000 TO
1500 J/KG OF MLCAPE AND 0 TO 6 KM SHEAR VALUES OF 30 TO 40 KNOTS.
SOME OF THESE THUNDERSTORMS WILL LIKELY BECOME SEVERE AND PRODUCE
DAMAGING STRAIGHT LINE WINDS THROUGH EARLY THIS EVENING. ALSO...A
SECONDARY CONCERN WILL BE LARGE HAIL WITH ANY STORM THAT ROTATES.
THERE ALSO IS A LOW PROBABILITY OF A TORNADO WITH 0 TO 1 KM HELICITY
VALUES ARE CURRENTLY AROUND 100 M/S ACROSS THE REGION. A SEVERE
THUNDERSTORM WATCH IS IN EFFECT UNTIL 11 PM FOR MOST OF OUR
REGION...EXCEPT FOR THE CAPE/ISLANDS.
ADDITIONAL SHOWERS AND THUNDERSTORMS ARE ALSO EXPECTED TO MOVE INTO
THE REGION DURING THE OVERNIGHT HOURS FROM THE MID ATLANTIC STATES.
IN FACT...BOTH THE GFS/NAM SHOW 0 TO 6 KM SHEAR VALUES INCREASING TO
BETWEEN 40 AND 50 KNOTS LATER THIS EVENING AND OVERNIGHT HOURS.
SURFACE DEWPOINTS NEAR 70 SHOULD RESULT IN SURFACE CAPE VALUES
REMAINING IN THE 500 TO 1000 J/KG RANGE. THEREFORE...THE POTENTIAL
FOR A FEW ADDITIONAL SEVERE THUNDERSTORMS WILL REMAIN POSSIBLE
DURING THE OVERNIGHT HOURS. FINALLY...PWAT VALUES APPROACHING 2
INCHES WILL BRING HEAVY RAIN WITH THE STORMS AS WELL AS THE RISK FOR
LOCALIZED FLOODING. WE HAVE EXPANDED THE FLOOD WATCH INTO SOUTHERN
NH.
&&
.SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/...
MONDAY...
THE SHOWERS AND THUNDERSTORMS SHOULD EXIT THE REGION SOMETIME DURING
THE EARLY TO MID MORNING HOURS. WE MAY HAVE A FEW HOURS OF DRY
WEATHER DURING THE MORNING AND POSSIBLY SOME DECENT SUNSHINE.
HOWEVER...ANOTHER SHORTWAVE IN SOUTHWEST FLOW ALOFT WILL LIKELY
TRIGGER ANOTHER ROUND SCATTERED SHOWERS AND THUNDERSTORMS DURING THE
AFTERNOON AND EVENING. 0 TO 6 KM SHEAR VALUES OF 35 TO 40 KNOTS AND
DECENT INSTABILITY WILL BRING THE POTENTIAL FOR SCATTERED SEVERE
THUNDERSTORMS.
MONDAY NIGHT...
THE FOCUS FOR SHOWERS/THUNDERSTORMS DURING THE EVENING SHOULD
GRADUALLY PUSH INTO OUR SOUTHERN ZONES. THE BULK OF THE ACTION
SHOULD BE OVER BY LATE EVENING. AREAS OF FOG...PERHAPS LOCALLY DENSE
WILL AFFECT THE REGION WITH LOTS OF LOW LEVEL MOISTURE IN THE REGION.
&&
.LONG TERM /TUESDAY THROUGH SUNDAY/...
TUESDAY AND WEDNESDAY...
UPPER AIR PATTERN REMAINS UNCHANGED WITH VORTEX SOUTH OF HUDSON BAY
YIELDING BROAD CYCLONIC FLOW ACROSS THE NORTHEAST. HOWEVER THERE IS
SOME SHORT WAVE RIDGING /ALBEIT WEAK/ THAT DEVELOPS OVER SOUTHERN
NEW ENGLAND BEHIND DEPARTING SHORT WAVE MON AND NEXT SHORT WAVE TROF
PROGGED TO ARRIVE HERE LATE WED OR WED NIGHT. THEREFORE SHOULD BE
SUFFICIENT SUBSIDENCE AND DEEP LAYER DRY AIR /AT LEAST IN THE MID
AND UPPER LEVELS/ FOR MAINLY DRY WEATHER WITH ANY SHOWER/TSTM
DEVELOPMENT TO BE ISOLATED OR WIDELY SCATTERED. THE EXCEPTION WILL
BE EARLY TUE AS SURFACE TROF MAY BE SLOW TO DEPART SOUTHEAST MA.
THEREFORE THE RISK OF SHOWERS/TSTMS MAY LINGER ACROSS THIS AREA INTO
TUE MORNING. HOWEVER A DRYING TREND IS EXPECTED AS THE DAY
PROGRESSES.
A GREATER CHANCE OF SHOWERS AND TSTMS WILL BE WED NIGHT AHEAD OF AN
APPROACHING SHORT WAVE AND ATTENDING FRONTAL BOUNDARY FROM THE WEST.
IT WILL REMAIN WARM AND MUGGY TUE AND WED WITH DEW PTS 65 TO 70 TUE
AND POSSIBLY LOW TO MID 70S WED. NAM AND GFS BOTH OFF 850 MB TEMPS
OF AROUND +15C/+16C. THIS COMBINED WITH SSW SURFACE WINDS AND GOOD
BOUNDARY LAYER MIXING WILL SUPPORT DAYTIME HIGHS WELL INTO THE 80S.
COOLER TEMPS EXPECTED ALONG THE SOUTH COAST OF MA AND RI GIVEN SSW
SURFACE WINDS. THERE IS A LOW PROBABILITY THAT A FEW LOCATIONS MAY
HIT 90 DEG WED AS 850 TEMPS PUSH +16C/+17C. HIGH DEW PTS WILL ALSO
KEEP OVERNIGHT MINS IN THE UPPER 60S TO LOW 70S. BOTTOM LINE...VERY
SUMMER LIKE.
THURSDAY THROUGH SUNDAY...
BROAD MID LEVEL TROF REMAINS OVER THE GREAT LAKES INTO NEW ENGLAND
THIS PERIOD...AS ANOMALOUS RIDGE BUILDS NORTHWARD INTO WESTERN
CANADA /+PNA/. DIFFICULT TO TIME THE EMBEDDED SHORT WAVES/JET
STREAKS WITHIN THIS BROAD FLOW...BUT IN THE MEDIUM RANGE THERE IS
ABOVE AVERAGE AGREEMENT AMONG 12Z ECMWF/GFS AND GGEM OF A MODEST
SHORT WAVE AND ATTENDING COLD FRONT TO MOVE ACROSS THE REGION WED
NIGHT INTO THU. THEREFORE HIGHEST POPS WILL PLACED IN THIS TIME
PERIOD. THEREAFTER /FRI THRU SUN/ EXPECT MAINLY DRY WEATHER WITH A
SLIGHT CHANCE TO CHANCE OF A SHOWER OR TSTM AT ANY TIME WITH
PROBABLY THE HIGHEST CHANCE DURING THE AFTN AND EARLY EVENING.
AS FOR TEMPS...HIGHS IN THE 80S SHOULD CONTINUE WITH 850 TEMPS
AROUND +15C. HUMID CONDITIONS WILL CONTINUE AS WELL WITH DEW PTS IN
THE 60S...ALSO YIELDING WARM NIGHTS.
&&
.AVIATION /21Z SUNDAY THROUGH FRIDAY/...
TONIGHT...SCATTERED SHOWERS ADN THUNDERSTORMS WILL BRING POCKETS OF
MVFR/IFR CONDITIONS TO THE REGION. IN ADDITION...LOW CLOUDS AND FOG
PATCHES WILL LIKELY RE-DEVELOP TONIGHT BRINGING WIDESPREAD IFR
MONDAY...IFR CONDITIONS IN LOW CLOUDS AND FOG PATCHES SHOULD IMPROVE
TO MARGINAL MVFR/VFR LATER IN THE MORNING/AFTERNOON. THE EXCEPTION
MIGHT BE THE FMH/HYA/ACK SITES WHERE LOW CLOUDS AND FOG PATCHES MAY
HANG TOUGH. IN ADDITION...SCATTERED SHOWERS/THUNDERSTORMS SHOULD
RE-DEVELOP DURING THE AFTERNOON BRINGING LOCALIZED MVFR/IFR
CONDITIONS.
OUTLOOK /TUESDAY THROUGH THURSDAY/...
VFR CONDITIONS EXPECTED DURING THE DAYTIME HOURS WHILE PATCHY FOG
AND LOW CLOUDS WILL BRING CONDITIONS DOWN TO MVFR/IFR DURING THE
OVERNIGHT HOURS INTO EARLY MORNING EACH DAY. MVFR/IFR MAY BECOME
MORE WIDESPREAD WED NIGHT INTO THU AS SHOWERS AND TSTMS ACCOMPANY
THE PASSAGE OF A COLD FRONT. IMPROVING CONDITIONS LATER THU INTO
FRI.
&&
.MARINE...
SCA ADVISORIES POSTED FOR OUR SOUTHERN OUTER-WATERS TONIGHT THROUGH
MONDAY NIGHT. WNA MODEL IS OVERDONE WITH ITS WAVE HEIGHT
FORECASTS...BUT DO EXPECT 4 TO 6 FOOT SEAS TO DEVELOP WITH
PERSISTENT SOUTHWEST FLOW LATER TONIGHT AND CONTINUE THROUGH MONDAY
NIGHT. WE ALSO MAY NEED NEAR SHORE SCA HEADLINES MONDAY AFTERNOON AS
GOOD MIXING OVER LAND MAY SUPPORT 25 KNOT WIND GUSTS.
THE OTHER CONCERNS WILL BE FOR AREAS OF FOG...WHICH WILL BE LOCALLY
DENSE ESPECIALLY DURING THE OVERNIGHT AND EARLY MORNING HOURS.
CONVECTION WILL ALSO AFFECT PORTIONS OF THE WATERS TONIGHT AS WELL
AS MONDAY AFTERNOON AND EVENING.
OUTLOOK /TUESDAY THROUGH FRIDAY/...
TRANQUIL WEATHER TUE AND WED WITH POSSIBLY SOME LEFTOVER SHOWERS
SOUTH COAST TUE. POOR VSBY AT NIGHT AND EARLY MORNING IN PATCHY
DENSE FOG. SHOWERS AND TSTMS MAY BECOME WIDESPREAD WED NIGHT AND THU
AS COLD FRONT APPROACHES THE REGION. IMPROVING WEATHER LATER THU
INTO FRI.
&&
.HYDROLOGY...
WITH 70+ DEWPOINTS IN PLACE AND PWAT VALUES APPROACHING 2 INCHES A
FLASH FLOOD WATCH IS IN EFFECT MAINLY ALONG AND NORTHWEST OF A
BOSTON TO PROVIDENCE LINE. SOME STORMS WILL BE CAPABLE OF DROPPING
1 TO 2 INCHES OF RAIN IN A VERY SHORT TIME. CONCERN IS HEIGHTENED
AS A RESULT OF THE SATURATED GROUND FROM THE RECENT HEAVY RAINS.
