AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
1028 AM EDT FRI AUG 9 2013

.SYNOPSIS...

PERIODS OF HEAVY RAIN WITH EMBEDDED THUNDERSTORMS EXPECTED TODAY.
WET WEATHER WILL PUSH OFFSHORE AS A COLD FRONT SWEEPS ACROSS THE
REGION TONIGHT. HIGH PRESSURE WILL BUILD INTO SOUTHERN NEW ENGLAND
THIS WEEKEND WITH DRY AND PLEASANT CONDITIONS WITH SEASONABLE
TEMPERATURES. ANOTHER COLD FRONT MAY BRING A FEW SHOWERS AND
THUNDERSTORMS TO THE REGION TUESDAY AND TUESDAY NIGHT...BUT A
WASHOUT IS NOT EXPECTED. DRY WEATHER RETURNS FOR WEDNESDAY AND
THURSDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

1030 AM UPDATE...

BROAD DEEP-LAYER ASCENT OF THE WARM-MOIST CONVEYOR BELT WITH
TROPICAL CHARACTERISTICS IS PRESENTLY ONGOING ACROSS NEW ENGLAND
AHEAD OF AN APPROACHING COLD FRONT CURRENTLY SITUATED ACROSS THE
EASTERN GREAT LAKES REGION.

AS A RESULT...WIDESPREAD RAIN IS ENVELOPING THE REGION WITH
EMBEDDED HEAVIER SHOWERS AND ISOLATED THUNDERSTORMS. ONE-HOUR
RAINFALL AMOUNTS HAVE BEEN AROUND A QUARTER TO A HALF AN
INCH...BUT FURTHER SOUTH AND WEST RAINFALL AMOUNTS AROUND AND
EXCEEDING 1 INCH HAVE BEEN OBSERVED LIKELY WHERE LOW-LEVEL
CONVERGENCE BENEATH DEEP-LAYER LIFT IS MAXIMIZED.

ALSO SEEING THE BEGINNING ENHANCEMENT OF SOUTHWESTERLY FLOW AHEAD
OF THE APPROACHING COLD FRONT. DRAG DOWN OF MOMENTUM TO THE
SURFACE VIA RAIN PROCESSES IS YIELDING GUSTY WINDS ESPECIALLY
ALONG THE SOUTH COAST OF NEW ENGLAND.

EXPECTATIONS THIS AFTERNOON...

1.) FLOODING

FLASH FLOOD WATCH EXPANDED TO INCORPORATE NORTHERN CONNECTICUT AND
THE WORCESTER MASSACHUSETTS MUNICIPALITY. MAY NEED TO EXPAND
FURTHER SOUTH AND EAST LATER TODAY...AND OUT LATER IN TIME.

BROADLY...EXPECTING ENHANCEMENT OF LOW-LEVEL SOUTHWESTERLY WINDS
AHEAD OF THE APPROACHING THE COLD FRONT. THIS SHOULD FUEL
CONTINUED WIDESPREAD RAIN...WITH EMBEDDED HEAVIER SHOWERS AND
THUNDERSTORMS WHERE LOW-LEVEL CONVERGENCE IS MAXIMIZED. ONE-HOUR
RAINFALL RATES UP TO AROUND 1 INCH ANTICIPATED.

MONITORING THE SOUTHERN PERIPHERY OF THE RAIN SHIELD SOUTH AND
WEST ALONG WITH VISIBLE SATELLITE. WITH CLOUD BREAKS...EXPECT
BOUNDARY LAYER DESTABILIZATION AND THIS MAY YIELD STRONG TO
SEVERE THUNDERSTORMS THIS AFTERNOON TOWARDS EVENING WHICH MAY
PRODUCE ONE-HOUR RAINFALL RATES WELL IN EXCESS OF 1 INCH AN HOUR.

NO CERTAINTY ON WHERE EXACTLY THE GREATEST THREATS WILL
MATERIALIZE...OTHER THAN THE FACT THAT THE TIMING OF FLOODING
THREATS WILL CENTER AROUND NOW INTO THIS EVENING...INCORPORATING
THE AFTERNOON COMMUTE.

2.) SEVERE WEATHER

THE KEY TO THE INTENSITY OF SEVERE WEATHER IS SUBSEQUENT TO
WHETHER THE CLOUDS WILL BREAK ACROSS SOUTHERN NEW ENGLAND ALLOWING
FOR DAYTIME HEATING AND BOUNDARY LAYER DESTABILIZATION. THIS COULD
BE POSSIBLE INTO CONNECTICUT AND MAYBE RHODE ISLAND LATER BY THIS
AFTERNOON INTO EVENING.

CONSIDERING NOTABLE TURNING OF THE ATMOSPHERIC WIND PROFILE WITHIN
THE LOW-LEVELS AND STRONG EFFECTIVE SHEAR UP TO AROUND 35 KTS...
ALONG WITH INSTABILITY VALUES /MLCAPE/ POTENTIALLY RISING TO
AROUND 1000 J/KG...ECHO THE SPC CONVECTIVE OUTLOOK FOR POTENTIAL
STRONG TO DAMAGING WINDS ALONG WITH THE POSSIBILITY OF A BRIEF
TORNADO. WITH MARGINAL MID-LEVEL LAPSE RATES AND THIN CAPE
PROFILES...NOT ANTICIPATING LONG-LIVED STORMS.

FEEL THE ENHANCEMENT OF WINDS ALOFT COUPLED WITH DRAGGING OF
MOMENTUM TO THE SURFACE FURTHER HEIGHTENS THE THREAT OF STRONG TO
DAMAGING WINDS WITH ANY STORMS AND HEAVY RAIN CORES.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SATURDAY/...

TONIGHT...
EXPECT COLD FRONT TO WORK OFF THE COAST AS UPPER LEVEL SYSTEM
ROTATES ACROSS HUDSON BAY. GOOD W-NW FLOW WILL WORK IN BEHIND THE
FRONT...BRINGING COOLER AND DRIER AIR TO THE REGION. LEFTOVER
SHOWERS AND A THUNDERSTORM OR TWO MAY LINGER ALONG THE S
COAST...CAPE COD AND THE ISLANDS INTO THE EARLY MORNING HOURS.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...

BIG PICTURE/PREFERENCES...
SUBTROPICAL RIDGE HOLDS ACROSS THE SOUTHERN USA AND BUILDS OVER
THE ROCKIES INTO WESTERN CANADA. CLOSED UPPER LOW RIDES THROUGH
EASTERN CANADA. A SHORTWAVE DRIVES SOUTH FROM THE CANADIAN ARCTIC
AND GRABS THE OTHER LOW...FORMING A CLOSED CIRCULATION THAT
ROTATES AROUND NORTHERN QUEBEC. THE RIDGE WEST/TROUGH EAST PATTERN
MAINTAINS THROUGH MOST OF NEXT WEEK.

THE ECMWF DIGS A LITTLE DEEPER AND FARTHER SOUTH WITH THE SECOND
SHORTWAVE THAN DOES THE GFS.  IT IS ALSO A LITTLE SLOWER WITH THE
PASSAGE OF ITS ASSOCIATED SURFACE COLD FRONT TUESDAY/TUESDAY NIGHT.
THERMAL FIELDS ALOFT ARE A COUPLE OF DEGREES COOLER ON THE ECMWF VS
THE GFS THIS WEEKEND...AND EVEN A LITTLE MORE COOLER MID TO LATE
WEEK NEXT WEEK.

OUR MAIN PREFERENCE WAS HPC/WPC GRIDS WHERE AVAILABLE...A BLEND OF
ECMWF/GFS GRIDS OTHERWISE.

THE DAILIES...

SATURDAY THROUGH MONDAY...
AS THE CLOSED LOW PASSES TO OUR NORTH ACROSS CANADA...IT DRIVES A
COLD FRONT OFFSHORE EARLY SATURDAY. BY SUNRISE WE EXPECT THIS TO
BE MOVING OFFSHORE BUT COULD STILL BE CLOSE ENOUGH FOR A LINGERING
SHOWER OR TSTM ON THE CAPE AND ISLANDS. OTHERWISE THE TREND FOR
SATURDAY WILL BE CLEARING WITH DECREASING DEWPOINTS. MOS WAS A TAD
LIGHT ON POST FRONTAL WINDS...LAPSE RATES SHOW MIXING REACHING UP
INTO 20 KNOT NORTHWESTERLIES AND 25 KNOTS WOULD NOT BE A
SURPRISE. WE ADJUSTED GUST VALUES ACCORDINGLY.

HIGH PRESSURE FROM THE MIDWEST BUILDS IN FOR SUNDAY AND MONDAY.
EXPECT DRY WEATHER. MOISTURE FIELDS DO SUGGEST SOME CLOUDS PART OF
THE TIME BUT NO PRECIPITATION.  THE GFS SHOWS MIXING REACHING TO 850
MB EACH DAY...BUT THE MODEL TENDS TO UNDERFORECAST THE ACTUAL DEPTH.
THE NAM MIXES TO 825 MB SATURDAY AND 850 MB SUNDAY.  WE ASSUMED
MIXING TO 800 MB INLAND WHERE TEMPS ARE 8C SAT AND SUN...AND 10C
MONDAY.  SO MAX TEMPS SHOULD REACH THE LOW TO MID 80S INLAND.  LIGHT
FLOW WILL ALLOW SEABREEZES TO DEVELOP SUNDAY.  NOT SURE ABOUT MONDAY.

TUESDAY...
THE SHORTWAVE FROM THE FAR NORTH SWINGS EAST ACROSS CANADA ON
TUESDAY. THE GFS HAS THIS BRINGING A SURFACE COLD FRONT THROUGH
NEW ENGLAND TUESDAY AFTERNOON/EVENING. THE ECMWF...BEING DEEPER
ALOFT...IS ALSO SLOWER BRINGING THE COLD FRONT ACROSS NEW ENGLAND
WITH TIMING MORE LIKE TUESDAY NIGHT. EITHER WAY...THE FRONT HAS
UPPER SUPPORT FROM THE RIGHT ENTRANCE REGION OF A 95 KNOT JET.
PRECIP WATER VALUES JUMP BACK TO AROUND 1.5 INCHES. PUT IT
TOGETHER...EXPECT A CHANCE OF SHOWERS WITH THE FROPA.

WEDNESDAY-THURSDAY...
HIGH PRESSURE BUILDS OVER THE REGION WITH A RETURN TO DRY AIR AND
NO PRECIP. THE UPPER TROUGH WILL MEAN COOLER TEMPS ALOFT...THE
ECMWF HAS 850 TEMPS 10C WEDNESDAY AND 7C THURSDAY. SEASONABLE TO
SEASONABLY COOL TEMPS WITH HIGHS MAINLY IN THE 70S AND LOWS IN THE
50S...POSSIBLY A FEW HIGH 40S.

&&

.AVIATION /14Z FRIDAY THROUGH TUESDAY/...

FORECASTER CONFIDENCE LEVELS...

LOW...LESS THAN 30 PERCENT.
MODERATE...30 TO 60 PERCENT.
HIGH...GREATER THAN 60 PERCENT.

OVERVIEW /THROUGH TONIGHT/...MODERATE CONFIDENCE.

15Z UPDATE...

MVFR-IFR CIGS PREVAILING WITH TEMPO MVFR-IFR VSBYS AT TIME LIKELY
WITH +RA. TRENDS WILL BE TROUBLESOME AND THE TAFS AT TIMES WILL
NOT BE PREVAILING CORRECTLY AS IT IS TEDIOUS TO TIME 1-2SM +RA BR.

OTHERWISE MAY SEE SOME CLEARING OVER FAR SOUTHERN NEW ENGLAND AS
BROKEN CLOUD DECKS SLOWLY MOVE NORTH AND EAST OUT OF THE DELMARVA
PENINSULA REGION LATE. DIFFICULT TO PIN DOWN POTENTIAL TSRA. IF
WE SEE SOME SUN THERE A GOOD CHANCE...HAVE BETTER CONFIDENCE OVER
N CT AND MAY NEED TO EXPAND INTO RI. WITH ANY TSRA...THERE IS A
THREAT OF STRONG TO DAMAGING WINDS.

SOUTHWEST WINDS BECOMING BLUSTERY INTO AFTERNOON. GUSTS 20-25 KTS
THE GREATEST OF WHICH WILL BE ALONG THE SOUTH-COAST INCLUDING THE
CAPE AND ISLANDS.

WILL SEE A GRADUAL CLEARING TREND NORTHWEST TO SOUTHEAST AS A COLD
FRONT SWEEPS ACROSS THE TERMINALS INTO SATURDAY MORNING. MVFR
CONDITIONS LINGER.

KBOS TERMINAL...MODERATE CONFIDENCE IN TAF

KBDL TERMINAL...MODERATE CONFIDENCE IN TAF. HAVE A MENTION OF VCTS
FOR THE AFTERNOON INTO EVENING PERIOD.

OUTLOOK...SATURDAY THROUGH TUESDAY...

SATURDAY...LINGERING MVFR VSBYS CAPE AND ISLANDS AT SUNRISE. MOST
AREAS SHOULD BE VFR AND THE TREND IN ANY CASE WILL BE IN THAT
DIRECTION.  NORTHWEST WINDS WILL BECOME GUSTY WITH 20-KNOTS EXPECTED
AND 25 KNOTS NOT OUT OF THE QUESTION. THE STRONGER GUSTS WILL BE
MAINLY AFTERNOON AND THEN DIMINISH IN THE EVENING.

SUNDAY-MONDAY...VFR WITH LIGHT WINDS.  SEA BREEZES ALONG THE COAST
WITH DAYTIME WIND SHIFTS TO SOUTHEAST AT BOSTON AND POSSIBLY
PROVIDENCE. PATCHY LOW VSBYS IN EARLY MORNING FOG EACH DAY.

TUESDAY...COLD FRONT MOVES THROUGH DURING AFTERNOON OR EARLY NIGHT.
THIS MAY BRING SCATTERED SHOWERS/TSTMS WITH BRIEFLY LOWER CIGS AND
VSBYS. OTHERWISE VFR.

&&

.MARINE...

FORECASTER CONFIDENCE LEVELS...

LOW...LESS THAN 30 PERCENT.
MODERATE...30 TO 60 PERCENT.
HIGH...GREATER THAN 60 PERCENT.

OVERVIEW /THROUGH TONIGHT/...MODERATE CONFIDENCE.

EXPECT SW WINDS TO INCREASE...GUSTING UP TO 25-30 KT OVER THE OPEN
WATERS INTO THIS EVENING. SEAS WILL BUILD UP TO 5-8 FT...HIGHEST
ON THE SOUTHERN OUTER WATERS. WILL WILL DIMINISH TONIGHT AS THEY
SHIFT TO W-NW BEHIND THE COLD FRONT BUT SEAS AOA 5 FT WILL LINGER.
PATCHY FOG AND SHOWERS/TSTMS WILL CAUSE REDUCED VSBYS AT TIMES.
MAY SEE SQUALLY CONDITIONS IN ANY TSTMS.

OUTLOOK...SATURDAY THROUGH TUESDAY...MODERATE CONFIDENCE.

SATURDAY...LINGERING ROUGH SEAS ON THE SOUTHERN OUTER WATERS DURING
THE MORNING...BUT SEAS WILL DIMINISH IN THE AFTERNOON.  NORTHWEST
WINDS GUSTING AROUND 20 KNOTS IN THE AFTERNOON ESPECIALLY AROUND
MASSACHUSETTS BAY.

SUNDAY AND MONDAY...WINDS AND SEAS SHOULD BE BELOW SMALL CRAFT
LEVELS.

TUESDAY...A COLD FRONT APPROACHES NEW ENGLAND AND MAY BRING A SHOWER
OR TSTM TO THE WATERS IN THE AFTERNOON.  SOUTHWEST WINDS PICK UP A
LITTLE BUT SHOULD STAY BELOW 25 KNOTS. SEAS REMAIN BELOW 5 FEET.

&&

.HYDROLOGY...

VERY WARM AND HUMID AIRMASS IN PLACE ALONG WITH INCREASING PWATS...
2 TO 2.5 INCHES BY THIS AFTERNOON...WILL CAUSE LOCALLY HEAVY RAINFALL.
RAINFALL AMOUNTS WILL AVERAGE FROM 1 TO 3 INCHES...WITH LOCALIZED
AMOUNTS UP TO 4 INCHES OR MORE. THE FRONT MAY SLOW FOR A TIME OVER
S NH/N MA DURING THE DAY BEFORE A SHORT WAVE MOVES ACROSS...
PUSHING IT ALONG LATER TODAY AND TONIGHT. THOSE AREAS THAT ARE
PRONE TO QUICKLY RISING SMALL STREAMS AS WELL AS URBAN AND POOR
DRAINAGE FLOODING WILL BE SUSCEPTIBLE ESPECIALLY IF ANY RAIN SLOWS
AND TRAINS OVER THE SAME AREAS.

FLASH FLOOD WATCH CONTINUES FOR SOUTHERN NEW HAMPSHIRE...WESTERN
AND CENTRAL MASSACHUSETTS...AND NORTHERN CONNECTICUT.
