AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
248 PM EDT WED MAY 16 2007

.SYNOPSIS...
A WEAK BACK DOOR COLD FRONT HAS SLIPPED DOWN OVER ESSEX COUNTY AND AS
FAR WEST AS FITCHBURG. THE WESTERN PORTION OF THIS FRONT WILL LIFT
BACK NORTH AS WARM FRONT. HOWEVER EXPECT ESSEX COUNTY TO REMAIN IN A
NORTHEAST FLOW OFF THE OCEAN FOR MUCH OF THE DAY. MEANWHILE A LOW
PRESSURE CENTERED NEAR LAKE ONTARIO AND ITS ASSOCIATED COLD FRONT
WILL MOVE ACROSS SOUTHERN NEW ENGLAND THIS AFTERNOON AND EARLY
TONIGHT. THE FRONT WILL STALL EAST OF NEW ENGLAND...WHILE LOW
PRESSURE DEVELOPS OFF THE SOUTHEAST U.S. COAST. THIS LOW WILL MAKE
ITS WAY UP THE EASTERN SEABOARD THURSDAY...THEN WILL SLOW AS IT
APPROACHES SOUTHERN NEW ENGLAND LATER FRIDAY AND THROUGH THE WEEKEND.
THIS WILL BRING A PERIOD OF RAINFALL TO MOST OF THE REGION...
ESPECIALLY ACROSS EASTERN AND CENTRAL AREAS. THE LOW WILL SLOWLY
SHIFT EAST DURING MONDAY AS ANOTHER COLD FRONT APPROACHES. HIGH
PRESSURE WILL TAKE OVER TUESDAY AND NEXT WEDNESDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
TORNADO WATCH 277 IN EFFECT UNTIL 6 PM FOR NORTHERN CT...NORTHERN RI...
WESTERN AND CENTRAL MA AND CHESHIRE COUNTY NH.

FRONT HAS MOVED LITTLE THIS AFTERNOON AND EXTENDS FROM ORANGE TO
WORCESTER...NORWOOD AND MARSHFIELD. STORMS CONTINUE TO FORM OVER
CENTRAL/WESTERN MA WHERE STRONG MOISTURE CONVERGENCE IS LOCATED ALONG
WITH SUFFICIENT INSTABILITY...BUT CONVECTION BECOMES MORE ELEVATED AS
IT RIDES ONTO COOL SIDE OF BOUNDARY.

WE HAVE SEEN STORMS ORGANIZE INTO BOWS OR LINE SEGMENTS WITH A FEW
SHOWING POTENTIAL FOR 50KT WINDS...ESPECIALLY IN WORCESTER COUNTY...
BUT ALSO IN NORTHERN CT. THESE STORMS WILL CONTINUE TO BRING THREAT
OF STRONG WINDS AS THEY HEAD THROUGH CT AND CENTRAL MA...BUT SHOULD
WEAKEN AS THEY ENTER EASTERN MA.

FARTHER UPSTREAM...MORE ACTIVITY HAS FIRED ACROSS EASTERN PA AND
NORTHERN NJ AND THAT WILL GET INTO SOUTHERN NEW ENGLAND A BIT LATER
THIS AFTERNOON.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM THURSDAY/...
HEAVY RAFL WILL BE A THREAT ACROSS EASTERN ZONES TONIGHT AS COLD
FRONT PUSHES EWD ACROSS THE REGION.  STRONG LOW LEVEL CONVERGENCE
ACTING ON HIGH PWATS GREATER THAN 1.5 WILL BRING HEAVY RAIN.
THUNDERSTORMS WILL ALSO BE LIKELY BUT INSTABILITY IS MAINLY ELEVATED
THIS EVENING IN THE EAST SO SEVERE THREAT IS MARGINAL.

SIGNIFICANT LOW CLOUDINESS WILL PERSIST IN THE WAKE OF THE FRONT AS
WINDS TURN TO THE NORTHEAST TONIGHT ACROSS THE REGION.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
MEDIUM RANGE MODELS APPEAR TO BE IN TWO CAMPS WITH THE EVOLUTION OF
A DEVELOPING CUTOFF UPPER LEVEL LOW AND LONG WAVE TROUGH ALONG THE
EASTERN SEABOARD...WHICH WILL HAVE BIG IMPLICATIONS IN DETERMINING
THE SENSIBLE WEATHER FOR THE FRIDAY-MONDAY TIMEFRAME. TWO MAIN
MODELS...THE GFS AND CANADIAN GGEM...HAVE NOT BEEN NEARLY AS
AMPLIFIED WITH THE LONG WAVE TROUGH...KEEPING IT MORE PROGRESSIVE.
THREE OTHER MODELS...THE WRF/NAM...ECMWF AND UKMET...HAVE BEEN
CONSISTENT IN A DEEPER LONG WAVE TROUGH AND CUTOFF SYSTEM FURTHER
WEST ALONG THE EASTERN SEABOARD BY THE END OF THE WEEK. NOTED A
VERY IMPRESSIVE SHORT WAVE DIVING OUT OF CENTRAL CANADA INTO
NORTHERN MINNESOTA AND LAKE SUPERIOR ON THIS MORNINGS WATER VAPOR
CHANNEL SATELLITE...WHICH WOULD LEND CREDENCE TO THE MORE AMPLIFIED
SOLUTION. THIS IS THE WAY THIS FORECAST PACKAGE HAS LEANED.

TODAYS COLD FRONT WILL STALL EAST OF NEW ENGLAND BY THURSDAY
MORNING. A WEAK HIGH PRESSURE RIDGE WILL BUILD INTO CENTRAL AND
NORTHERN NEW ENGLAND...BUT THE REGION WILL REMAIN IN A COOL
NORTHEAST FLOW WITH CLOUDS LINGERING ALONG THE EAST COAST...AND
ESPECIALLY THE CAPE AND ISLANDS.  DURING THIS...LOW PRESSURE WILL
DEVELOP OFF THE FLORIDA COAST AND...WITH THE DEVELOPING LONG WAVE
TROUGH OVER THE MID ATLANTIC STATES...WILL WORK SLOWLY NORTHWARD
ALONG THE STALLED FRONT. EXPECT CLOUDS TO MOVE BACK INTO THE REGION
FROM S-N THURSDAY NIGHT...AND EVEN THE THREAT OF SHOWERS MOVING IN
OFF THE OCEAN AS THE DEFORMATION ZONE SHIFTS BACK NORTHWESTWARD.
HAVE CARRIED BEST CHANCE OF PRECIPITATION ALONG THE COAST AND OVER
THE CAPE AND ISLANDS ON FRIDAY AND FRIDAY NIGHT.

BY SATURDAY MORNING...EXPECT THE SURFACE LOW TO BE S OF NEW ENGLAND.
FROM THERE...THE MODELS ARE HAVING A DIFFICULT TIME ON ITS MOVEMENT
AS THE SURFACE SYSTEM MAY BECOME CAPTURED BY THE CUTOFF UPPER LEVEL
LOW...WHICH BY SATURDAY MAY BE NEAR THE DELMARVA PENINSULA. BOTH THE
WRF/NAM AND EC TRY TO BRING IT NEAR THE LONG ISLAND/CT COAST DURING
SATURDAY...THEN THE EC TRIES TO LOOP IT BACK TOWARD NYC AND THE NJ
COAST BY SUNDAY MORNING. NCEP IS LEANING TOWARD THIS SOLUTION...
WHICH WILL KEEP THE REGION IN A PRETTY GOOD...LONG TERM ONSHORE FLOW
THROUGH THIS WEEKEND AND INTO MONDAY. THE LOW IS NOT TERRIBLY
STRONG...BUT WILL BE A PRETTY GOOD SLUG OF MOISTURE DUE TO THE LOWS
TROPICAL CONNECTION. AT THIS POINT...WENT WITH QPF TOTALS ON THE
ORDER OF 0.75 TO 1.25 IN THE FRIDAY-SATURDAY TIMEFRAME...WITH THE
HIGHEST AMOUNTS NEAR THE COAST.  WOULD NOT BE SURPRISED TO SEE THESE
INCREASE. THIS WILL NEED TO BE MONITORED. ALSO...PROLONGED NORTHEAST
WINDS...THOUGH NOT QUITE TO WIND ADVISORY CRITERIA...MAY BRING THE
SEAS UP OVER THE WEEKEND INTO MONDAY.

NEEDLESS TO SAY...NOT A WHOLE LOT OF CONFIDENCE WITH THIS PORTION OF
THE FORECAST...BUT A LITTLE MORE THAN YESTERDAY. STARTING
SATURDAY...KEPT CHANCE POPS GOING FOR NOW...BUT FEEL THESE WILL
INCREASE LATER TODAY FOR THE SATURDAY NIGHT AND SUNDAY TIME PERIODS.

APPEARS THAT THE CUTOFF LOW WILL SLOWLY SHIFT EAST...PUSHING THE LOW
OUT TO SEA DURING MONDAY. A RATHER STRONG COLD FRONT MAY APPROACH
FROM THE NORTHWEST TO AID IN THIS MOVEMENT. BY TUESDAY...HIGH
PRESSURE APPEARS TO TAKE OVER...WHICH WILL CONTINUE INTO NEXT
WEDNESDAY.

&&

.AVIATION /19Z WEDNESDAY THROUGH MONDAY/...
SKIES HAVE CLEARED OUT OVER ALL OF SOUTHERN NEW ENGLAND EARLY THIS
MORNING. ONLY A FEW LOCATIONS HAD SOME LOCALLY DENSE FOG...SUCH AS
AT WESTOVER AIRPORT. THIS SHOULD BURN OFF RAPIDLY AFTER SUNRISE
SINCE THERE IS NO CLOUD COVER ABOVE IT.

EXPECT SCATTERED CUMULUS TO FORM AT 4000 FT LATE THIS MORNING AND
EARLY AFTERNOON. THEN EXPECT A SQUALL LINE OF SEVERE THUNDERSTORMS
TO MOVE INTO WESTERN MA AND WESTERN CT AROUND 19Z...SPREADING
EASTWARD TO THE COAST BY 00Z. WIND GUSTS TO 45 KNOTS ARE MENTIONED
IN THE TERMINAL FORECASTS...HOWEVER GUSTS TO 60-70 KNOTS IN THE
STRONGEST STORMS WILL BE POSSIBLE.  PLEASE SEE SHORT TERM FORECAST
SECTION ABOVE FOR DETAILS ON WHY THIS SQUALL LINE IS EXPECTED.
ASSUMING IT DOES FORM...IFR VISIBILITY AND MVFR CIG CONDITIONS ARE
EXPECTED IN THE THUNDERSTORMS.

A BACKDOOR COLD FRONT WILL PLAY HAVOC WITH WIND DIRECTION AT LOGAN
AIRPORT. AM PREDICTING THAT LIGHT NORTHEAST WINDS WILL BE TEMPORARY
EARLY THIS MORNING...BECOMING SOUTH-SOUTHWEST AS THE LOW APPROACHES
FROM THE WEST...THEN BACK TO THE NORTHEAST THIS EVENING AFTER THE
CONVECTIVE LINE PASSES THROUGH.

MODEL GUIDANCE FORECASTS CEILINGS AROUND 1000 FT TONIGHT...
ESPECIALLY FOR MHT/ORH/BOS/HYA/ACK...AS THE NORTHEAST WINDS TAKE
HOLD.

OUTLOOK THURSDAY THROUGH SUNDAY...
LOCAL MVFR CEILINGS AND VSBYS ARE POSSIBLE THURSDAY MORNING ACROSS
CENTRAL AND EASTERN AREAS...BUT WILL IMPROVE TO VFR BY MIDDAY.
HOWEVER...MVFR CEILINGS MAY LINGER ON CAPE COD AND THE ISLANDS. VFR
CONDITIONS WILL CONTINUE EARLY THURSDAY NIGHT...THEN MVFR CEILINGS
WILL APPROACH THE SOUTH COAST AFTER MIDNIGHT.

BY FRIDAY MORNING...MOST AREAS WILL HAVE MVFR-IFR CEILINGS AND VSBYS
WITH RAIN MOVING IN ESPECIALLY ACROSS CENTRAL AND EASTERN
MASSACHUSETTS...RHODE ISLAND AND EASTERN CONNECTICUT. EXPECT PERIODS
OF MVFR-IFR CEILINGS AND VSBYS TO CONTINUE THROUGH SATURDAY AND
SUNDAY AS LOW PRESSURE EITHER STALLS S OF NEW ENGLAND OR MOVES INTO
THE SOUTH COAST.

&&

.MARINE...
SHORT TERM...SMALL CRAFT ADVISORIES ARE POSTED FOR THE SOUTHERN
WATERS TODAY AND FOR ALL WATERS TONIGHT.  GUSTY SW WINDS WILL REACH
20-30 KNOTS TODAY.  NORTHEAST WINDS UP TO 20 TO 30 KNOTS WILL SNEAK
DOWN THE COAST INTO THE MERRIMACK TO PLYMOUTH WATERS LATE THIS
AFTERNOON AND TONIGHT.

A COLD FRONT WILL LIKELY TRIGGER A SQUALL LINE OF POTENTIALLY SEVERE
THUNDERSTORMS THIS AFTERNOON...EXITING THE COASTAL WATERS BETWEEN 7
PM AND 10 PM. HAIL AND DAMAGING WINDS ARE POSSIBLE...ALTHOUGH IT
WILL LIKELY BE STRONGEST OVER THE INTERIOR SECTIONS OF SOUTHERN NEW
ENGLAND DURING THE AFTERNOON.  THE ACTUAL FRONT WILL EXIT THE WATERS
BY EARLY THU.

LONG TERM...
WEAK HIGH PRESSURE WILL BUILD INTO NORTHERN NEW ENGLAND...BUT
NORTHEAST WINDS WILL CONTINUE AS THE FRONT REMAINS STALLED EAST OF
THE REGION THURSDAY NIGHT INTO FRIDAY.

LOW PRESSURE WILL MOVE UP THE COAST DURING FRIDAY...BRINGING A
SOMEWHAT STRONG PRESSURE GRADIENT...WITH SMALL CRAFT CONDITIONS
DEVELOPING ON THE OUTER WATERS AS WELL AS THE SOUTH SOUNDS AND
BUZZARDS BAY BY FRIDAY NIGHT AND CONTINUING THROUGH SATURDAY. GALE
FORCE GUSTS ARE POSSIBLE ON THE SOUTHERN OUTER WATERS SATURDAY
MORNING AS THE LOW APPROACHES THE WATERS.

DEPENDING UPON THE MOVEMENT OF THE LOW...WINDS MAY DIMINISH AS IT
CROSSES OVER THE WATERS TOWARD THE SOUTH COAST...THEN WILL LINGER
EITHER NEAR LONG ISLAND OR EVEN SHIFT SOUTH DURING SUNDAY.
HOWEVER...THERE COULD BE SOME SMALL CRAFT GUSTS ON THE EAST COAST
SATURDAY NIGHT INTO SUNDAY.  SEAS WILL ALSO REMAIN ABOVE 5 FEET
FRIDAY THROUGH SUNDAY.

THE EARLY SAT MORNING ASTRONOMICAL HIGH TIDE AT BOS IS HIGHER THAN
NORMAL AT 11.8 FEET BUT FORECASTED WAVE ACTION NOT HIGH ENOUGH TO
CAUSE SIGNIFICANT COASTAL FLOOD PROBLEM ALONG EAST COASTAL MA.
