AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
547 PM EDT TUE SEP 18 2012
.SYNOPSIS...
A COLD FRONT WILL BRING HEAVY RAIN AND A PERIOD OF STRONG TO
POSSIBLY DAMAGING WINDS TONIGHT. THREATS WILL DIMINISH INTO
WEDNESDAY MORNING AS THE COLD FRONT PUSHES OFFSHORE. MAINLY DRY
WEATHER WILL FOLLOW THROUGH THE FIRST PART OF SAT...OTHER THAN
PERHAPS A FEW SPOT SHOWERS ON THE COAST. ANOTHER COLD FRONT MAY
BRING A ROUND OF SHOWERS SOMETIME SATURDAY NIGHT AND/OR SUNDAY. DRY
WEATHER LIKELY FOLLOWS FOR THE START OF THE NEXT WORK WEEK.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
A STRONG BAROCLINIC TROF CONTINUES TO CYCLONICALLY DIG THRU THE GRT
LKS RGN AMPLIFIED BY AN ATTENDANT SHRTWV IMPULSE...USURPING ENERGY
AND SUB-TROPICAL MOISTURE FROM THE GULF OF MEXICO NEWD INTO NEW
ENGLAND. THE SUBSEQUENT ENHANCEMENT OF SFC-UPR LVL DYNAMICS IS
RESULTING IN STRONG ATMOS LIFT AND DEEPENING OF SFC LOW PRES
PRESENTLY ACROSS LAKE ONTARIO NEWD INTO THE ST LAWRENCE RVR VLY. THE
PRES COUPLET IS IMPRESSIVE RESULTING IN A STRONG PRES GRADIENT
AGAINST DOMINANT SFC HIGH PRES OVER THE ATLANTIC...RESULTING IN VERY
DOMINANT SFC-MID LVL SLY FLOW. CONSEQUENTIAL IMPACTS OF SUCH AN
ANOMALOUSLY STRONG SYNOPTIC SYSTEM ARE OUTLINED BELOW.
SEVERE WEATHER THREAT...
WATCHING CONVECTIVE ACTIVITY DEVELOPING ACROSS THE HUDSON VLY RGN IN
UPSTATE NY ALONG AND AHEAD OF A SFC COLD FRNT PRESENTLY N-S FROM
WATERTOWN NY INTO ERN PA CURVING SOUTHWESTWARD TOWARDS BLACKSBURG
VA.
AS THE COLD FRNT PROGRESSES EWD...A TONGUE OF ELEVATED INSTABILITY
/INDICATED BY LOW SHOWALTER AND SFC LIFTED INDICES/ WILL BUILD NWD
FUELING CONTINUING CONVECTIVE ACTIVITY ALONG AND AHEAD OF THE FRNT
IN THE FORM OF A NEAR-FRONTAL SQUALL LINE /SEEN IN THE RADAR
RETURNS WEST/ WITHIN THE ANTICIPATED HIGHLY SHEARED ENVIRONMENT.
HOW MUCH INSTABILITY REMAINS AN ISSUE. WEAK INSTABILITY WILL LEND
TO THE CONVECTIVE LINE WITH THE THREAT OF DAMAGING WINDS /PER HIGH
SHEAR AND PRECIPITATION DRAG PROCESSES MIXING-DOWN FASTER MOMENTUM
TO THE SFC...STRONGEST OF WHICH WILL BE ALONG AND AHEAD OF THE SFC
COLD FRNT/. BUT SHOULD SIGNIFICANT INSTABILITY DEVELOP ON THE
ORDER OF 500 J/KG COUPLED WITH THE HIGH SHEAR RESULTING IN PSBL
SUSTAINED UPDRAFTS...THEN THREATS OF DAMAGING WINDS ARE STILL
EXPECTED...BUT ALSO THERE IS THE PLAUSIBILITY OF ISOLATED
TORNADOES /THE HIGHLY SHEARED ENVIRONMENT EXHIBITS WELL-DEFINED
RIGHT TURNING HODOGRAPHS RESULTING IN IMPRESSIVE 0-1 AND 0-3 KM
HELICITY VALUES/. AM LEANING TOWARDS THE FORMER RATHER THAN THE
LATER. FEEL THE GREATEST THREAT WILL BE DAMAGING WINDS. THERE
COULD PSBLY BE AN ISOLATED BRIEF TORNADO THREAT...BUT HAVE LOW
CONFIDENCE.
THE SFC FRNT AND ATTENDANT THREATS WILL BE INTO THE WRN FCST AREA BY
DUSK...QUICKLY PROGRESSING ACROSS THE FCST AREA AND OFFSHORE AS LATE
AS WEDNESDAY MORNING. THE HEAVY RAIN THREAT IS OUTLINED BELOW.
HEAVY RAIN...
STRONG FRONTOGENETICAL LIFT OF A VERY MOIST SUB-TROPICAL ENVIRONMENT
AHEAD OF THE SFC COLD FRNT IS EXPECTED. PWATS AROUND 2 INCHES IS
ANTICIPATED WITH A CONDITIONALLY UNSTABLE MOIST ADIABATIC PROFILE.
THE HEAVIEST OF THE RAIN WILL BE ASSOC WITH THE AFOREMENTIONED
NEAR-FRONTAL SQUALL LINE AHEAD OF THE SFC COLD FRNT. RAINFALL
AMNTS OF 1 INCH PER HR WILL BE PSBL ALONG WITH VISIBILITY IMPACTS
WHICH CAN MAKE TRAVELING HAZARDOUS. TOTAL RAINFALL AMNTS WILL BE
AROUND 2 INCHES WITH LOCALLY HIGHER AMNTS.
WILL CONTINUE PRIOR THINKING OF THE GREATEST FLOODING THREAT TO BE
NUISANCE FLOODING OF URBAN AREAS ESPECIALLY WITH THE POSSIBILITY OF
HEAVY RAINFALL IN A SHORT PERIOD OF TIME. IT IS STILL PLAUSIBLE
SMALL BASINS...STREAMS...AND CREEKS MAY BECOME FLASHY...MAIN-STEM
RIVERS SHOULD BE FINE AS THE RGN HAS SEEN LITTLE RAIN OVER THE LAST
WEEK AND RIVERS REMAIN AT OR BELOW THEIR NORMAL LVLS.
WINDS...
WINDS CONTINUE TO INCREASE ACROSS THE RGN WITH GUSTS AROUND 40
MPH ACROSS NEW ENGLAND. AN AVERAGE OF 45 KT WINDS /55 MPH/ IS
PRESENTLY BEING OBSERVED AT H925 /2-3 KFT AGL/.
THINKING REMAINS THE SAME...STRONGEST OF WINDS CONTINUE TO PUSH
INTO NEW ENGLAND ALONG AND AHEAD OF THE COLD FRNT AS SFC LOW PRES
DEEPENS INTO THE ST LAWRENCE RVR VLY AGAINST HIGHER PRES INTO THE
ATLANTIC. WHILE A LLJ AXIS IS EXPECTED TO LIFT WITH THE SFC LOW
AND PARENT SHRTWV IMPULSE INTO THE ST LAWRENCE RVR VLY...A SECOND
JET AXIS IS EXPECTED TO AMPLIFY ALONG AND AHEAD OF THE COLD FRNT
AS IT APPROACHES THE SHORE /THIS DUE IN PART TO THE LACK OF SFC
FRICTIONAL IMPACTS OVER THE OCEAN AND DECOUPLING OF THE BOUNDARY
LYR/. MIX-DOWN OF FASTER MOMENTUM ALOFT IS EXPECTED INTO THE
EVENING WITH A CONDITIONALLY UNSTABLE ENVIRONMENT...YET THE
GREATEST POTENTIAL OF STRONG TO DAMAGING WINDS REACHING THE SFC
WILL BE WITH RGNS OF HEAVY RAINFALL...ESPECIALLY WITH THE
AFOREMENTIONED NEAR-FRONTAL SQUALL LINE ANTICIPATED TO SWEEP THRU
THE RGN AHEAD OF THE SFC COLD FRNT.
THE WIND ADVISORY CONTINUES TO PREVAIL WITH THE EXPECTATION OF
STRONG TO DAMAGING WINDS. IT IS POSSIBLE TO SEE HIGH WINDS REACH THE
SFC WITH GUSTS UP TO 60 MPH WITH THE FASTER JET EXPECTED AHEAD OF
THE FRONT PARENT WITH THE NEAR-FRONTAL SQUALL LINE /PRECIPITATION
DRAG OF FASTER MOMENTUM TO THE SFC/. HIGHER TERRAIN LOCALES ABOVE 1
KFT WILL ALSO BE UNDER RISK FOR A GREATER POSSIBILITY FOR HIGH WINDS
AT OR ABOVE 60 MPH.
COASTAL FLOODING...
SEE THE TIDES AND COASTAL FLOODING SECTION OF THE DISCUSSION BELOW.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH 6 PM WEDNESDAY/...
COLD FRNT AND ATTENDANT RAINS LINGER ALONG THE CAPE POSSIBLY FOR THE
FIRST HR OR TWO. OTHERWISE GRADUALLY CLEARING CONDITIONS WITH THE
EXPECTATION OF LOW-LVLS MIXING OUT DURING THE DAY WITH AMBIENT
SUNSHINE RESULTING IN FASTER W/NW FLOW ALOFT MIXING DOWN. DRIER AIR
MOVING INTO THE RGN...MAY SEE SOME DIURNAL CU THAT SHOULD QUICKLY
DISSIPATE. MAX TEMPS AROUND THE LOW 70S WITH GUSTY W/NW WINDS AROUND
15 MPH.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
HIGHLIGHTS...
* SLIGHTLY BELOW NORMAL TEMPS WED NIGHT AND THU
* MAINLY DRY THROUGH EARLY SAT OTHER THAN A SPOT SHOWER ON COAST
* A COLD FRONT MAY BRING A ROUND OF SHOWERS SOMETIME SAT NIGHT/SUN
* MAINLY DRY WEATHER LIKELY FOLLOWS NEXT MON-TUE
DETAILS...
WEDNESDAY NIGHT...
HIGH PRESSURE BUILDING ACROSS NEW ENGLAND BEHIND THE COLD FRONT WILL
BRING A DRY AND CHILLY NIGHT. LOW TEMPS WILL LIKELY BOTTOM OUT IN
THE MIDDLE TO UPPER 30S ACROSS THE NORMALLY COOLER OUTLYING
LOCATIONS OF SOUTHWEST NH/WESTERN MA...TO MAINLY THE 40S ELSEWHERE.
SOME FROST MAY OCCUR ACROSS OUR NORTHWEST INTERIOR ZONES...BUT ITS
UNCERTAIN WHETHER IT WILL BE WIDESPREAD ENOUGH TO WARRANT A FROST
ADVISORY. SOMETHING LATER SHIFTS WILL HAVE TO CONSIDER.
THURSDAY...
HIGH PRESSURE CENTERED OVER QUEBEC AND NORTHERN NEW ENGLAND WILL
RESULT IN GENERALLY DRY WEATHER WITH SLIGHTLY BELOW NORMAL TEMPS.
HIGH SHOULD BE HELD IN THE 60S TO AROUND 70...WITH THE COOLEST
READINGS ALONG THE COAST WITH AN ONSHORE FLOW.
THURSDAY NIGHT AND FRIDAY...
SOME UNCERTAINTY WITH A WEAK WAVE OF LOW PRESSURE TRACKING SOUTHEAST
OF THE BENCHMARK. IT LOOKS LIKE AT THIS POINT THAT MOST OF THE
PRECIPITATION WILL STAY OFFSHORE...ALTHOUGH A FEW SPOT SHOWERS MAY
GRAZE THE COAST. WE DID INCLUDE SOME LOW POPS FOR PERHAPS A FEW
SPOT SHOWERS ALONG THE COAST THU NIGHT/FRI WITH THE BEST CHANCE
ACROSS THE CAPE/NANTUCKET. HOWEVER...WERE STILL 60+ HOURS OUT SO
CAN/T COMPLETELY RULE OUT A WETTER SCENARIO IF LATER MODEL RUNS
TREND WEST. LATER SHIFTS WILL HAVE TO MONITOR TRENDS.
SATURDAY AND SUNDAY...
GENERALLY EXPECT A MILD AND MAINLY DRY DAY SATURDAY OUT AHEAD OF A
COLD FRONT. HIGH TEMPS SHOULD RECOVER WELL INTO THE 70S. A COLD
FRONT MAY BRING A ROUND OF SHOWERS SOMETIME SAT NIGHT AND/OR
SUNDAY...BUT TIMING IS LOW THIS FAR OUT.
MONDAY AND TUESDAY...
MAINLY DRY WEATHER WILL PROBABLY FOLLOW WITH NEAR OR JUST BELOW
NORMAL TEMPERATURES FOR THE BEGINNING OF THE NEXT WORK WEEK.
&&
.AVIATION /22Z TUESDAY THROUGH SUNDAY/...
FORECASTER CONFIDENCE LEVELS...
LOW...LESS THAN 30 PERCENT
MODERATE...30 PERCENT TO 60 PERCENT
HIGH...GREATER THAN 60 PERCENT
OVERVIEW...
MODERATE TO HIGH CONFIDENCE IN TRENDS INTO THE EVNG PD.
EXPECTATION IS FOR WINDS TO INCREASE AND CIGS TO LOWER AS THE SFC
COLD FRNT APPROACHES WITH A NEAR-FRONTAL SQUALL LINE /SEE IN THE
VICINITY OF KSYR/. ANTICIPATE THAT AS THE SQUALL LINE PUSHES
THRU THE TERMINALS...MVFR CIGS WILL PREVAIL WITH SOME INTERMITTENT
IFR. VSBYS WHILE PREVAILING MVFR MAY ALSO TEMPO IFR WITH +RA. LOW
CONFIDENCE ON TSRA...THINKING ISOLATED CHCS. MAY NEED TO BE
CONCERNED FOR ISOLATED TORNADOES. EXPECT STRONG TO DAMAGING SLY
WINDS GUSTING AROUND 40 KTS /MORESO ALONG THE EXPOSED S SHORE
TERMINALS/.
SFC COLD FRNT OUT BY MORNING...LINGERING ALONG THE CAPE. WINDS
BACK W/NW WITH GRADUAL CLEARING THRU THE DAY. ANTICIPATE
INCREASING GUSTS INTO THE MIDDAY-AFTN PD.
KBOS TAF...
MODERATE TO HIGH CONFIDENCE. CONVECTIVE LINE IS CENTERED AROUND
3Z WITH GREATEST IMPACTS.
KBDL TAF...
MODERATE TO HIGH CONFIDENCE. CONVECTIVE LINE IS CENTERED AROUND
0Z WITH GREATEST IMPACTS.
OUTLOOK...WEDNESDAY NIGHT THROUGH SATURDAY...
WEDNESDAY NIGHT THROUGH SATURDAY...
MODERATE CONFIDENCE. MAINLY VFR CONDITIONS EXPECTED OVER THIS TIME.
CAN/T RULE OUT A PERIOD OF MVFR CEILINGS ALONG THE COAST WITH
ONSHORE FLOW.
SATURDAY NIGHT AND SUNDAY...
LOW TO MODERATE CONFIDENCE. A PERIOD OF MVFR CONDITIONS ARE
POSSIBLE WITH A ROUND OF SHOWERS ASSOCIATED WITH A COLD FRONT. LOW
CONFIDENCE ON TIMING.
&&
.MARINE...
TONIGHT INTO WEDNESDAY...MODERATE CONFIDENCE.
COLD FRNT WILL SWEEP INTO THE WATERS AROUND MIDNIGHT...PUSHING
WELL OUT TO SEA AS LATE AS MIDDAY WEDNESDAY. CONVECTIVE ACTIVITY
IS EXPECTED WITH THE MAIN THREATS OF LIGHTNING...HEAVY RAIN...
REDUCED VISIBILITIES...AND STRONG WINDS ANTICIPATED. IN REGARDS TO
WINDS...STRONG SOUTHERLY FLOW IS EXPECTED AHEAD OF THE COLD FRNT
WITH GALE FORCE WINDS...BUT GUSTS UP TO 50 KTS /STORM FORCE/ ARE
PSBL. GALE WARNINGS REMAIN IN EFFECT. WAVES EXPECTED TO BUILD TO
AROUND 12 FT OVRNGT WITH THE SOUTHERLY FETCH GRADUALLY DIMINISHING
THRU WEDNESDAY.
IN WAKE OF THE COLD FRNT WEDNESDAY WINDS WILL BACK OUT OF THE W/NW
WITH GUSTS AROUND 15-20 KTS. CONDITIONS ACROSS THE WATERS SHOULD
DIMINISH TO SMALL CRAFT ADV ACCORDINGLY. SEAS LIKELY TO REMAIN
ABOVE 5 FT INTO THE EVNG PD.
OUTLOOK...WEDNESDAY NIGHT THROUGH SUNDAY...
MODERATE TO HIGH CONFIDENCE. NORTHEAST WINDS MAY GUST TO AROUND 25
KNOTS AT TIMES OVER THE OPEN OCEAN WED NIGHT INTO EARLY FRI IN THE
COOL AIR ADVECTION PATTERN. WHILE THE WINDS SHOULD DIMINISH SOME
LATER ON FRI...SCA SEAS MAY LINGER ACROSS THE OUTER-WATERS RIGHT
THROUGH THE WEEKEND. THIS A RESULT OF SWELL FROM A DISTANT LOW
PRESSURE SYSTEM WELL OFFSHORE.
&&
.TIDES/COASTAL FLOODING...
STRONG SOUTHERLY FLOW WILL BRING A STORM SURGE OF 1.5 TO PERHAPS 2
FEET TO SOUTH COASTAL MA/RI WITH TONIGHTS HIGH TIDE. THIS WILL
RESULT IN MINOR COASTAL FLOODING ESPECIALLY IN THE UPPER PARTS OF
BUZZARDS BAY AND NARRAGANSETT BAY WHERE CHANNELING MAY COME INTO
PLAY. A FEW LOCATIONS MAY EXPERIENCE BRIEF ROAD CLOSURES AROUND
THE TIME OF HIGH TIDE...OTHERWISE IMPACTS SHOULD BE MINIMAL.
USED ESTOFS STORM SURGE GUIDANCE BUT ADJUSTED SLIGHTLY UPWARD
BASED UPON AFTERNOON TIDAL DEPARTURES ABOUT A FOOT ALONG THE SOUTH
COAST. ETSS GUIDANCE IS WAY UNDERDONE AT ONLY HALF FOOT STORM
SURGE THIS EVENING.
