AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
410 PM EDT FRI AUG 10 2012
.SYNOPSIS...
UPPER LEVEL LOW GRADUALLY EJECTS OUT OF THE GREAT LAKES REGION
INTO THE SAINT LAWRENCE VALLEY. CONSEQUENTIALLY...A PERIOD OF
SHOWERS AND THUNDERSTORMS WITHIN A TROPICAL AIRMASS WILL CONTINUE
INTO THE END OF THE WEEK. THUNDERSTORMS MAY CONTAIN EMBEDDED HEAVY
DOWNPOURS POSING A LOCALIZED FLOODING THREAT. SOME STORMS MAY
BECOME SEVERE WITH DAMAGING WINDS.
DRIER AND LESS HUMID AIR RETURNS FOR LATE THIS WEEKEND INTO EARLY
NEXT WEEK. ANOTHER LOW PRESSURE WITH ASSOCIATED WARM AND COLD
FRONTS WILL IMPACT OUR REGION DURING THE MIDDLE OF NEXT WEEK.
&&
.NEAR TERM /UNTIL 9 PM THIS EVENING/...
4 PM UPDATE...
TORNADO WATCH 571 IN EFFECT ACROSS E/SE NEW ENGLAND. STRONG SHRTWV
DISTURBANCE ASSOCIATED WITH ROBUST CYCLONIC FLOW IS RESULTING IN
BRIEF SPIN-UPS ALONG THE S SHORELINE OF NEW ENGLAND. ALREADY...
TORNADO WARNINGS HAVE BEEN ISSUED ACROSS LONG ISLAND AND ADJACENT
WATERS AS WSR-88D HAS INDICATED DISCREET ROTATION ALONG THE S
PERIPHERY OF APPROACHING RAIN.
A TRAIN OF THOUGHT IS TO TREAT THE ONSHORE BANDING SIMILAR TO
TROPICAL RAINBANDS COMING ASHORE AHEAD OF A LAND FALLING
HURRICANE. STRONG CYCLONIC FLOW WITHIN THE SYS INTERACTING WITH
FRICTIONAL EFFECTS OF TOPOGRAPHY NETS BRIEF ISOLATED SPIN UPS.
THE ANTICIPATION WITH THE LATEST TORNADO WATCH IS THAT THE E
COASTAL PLAIN WHICH HAS SEEN LITTLE RAIN...BUT REGISTERS TEMPS
INTO THE LOW 80S WITH LOW 70 DWPTS...IS A PRIME ENVIRONMENT OF
INSTABILITY. COUPLED WITH THE LOW-MID LVL STRONG SHEAR ASSOC WITH
ONSHORE SHRTWV DISTURBANCE...AND THERE EXISTS THE POSSIBILITY FOR
BRIEF ISOLATED SPIN-UPS.
THE ACTIVITY SHOULD BE OUT OF THE RGN AROUND 8 PM. FLOODING
THREATS STILL PERSIST AS OUTLINE IN THE 2 PM DISCUSSION BELOW.
PRIOR DISCUSSION...
PRIOR TO...EXPECT IMPINGING LOW-LVL FLOW TO THE REAR OF THE
DISTURBANCE RESULTING IN A WIDESPREAD AREA OF RAIN WITH EMBEDDED
HEAVIER DOWNPOURS AND THUNDERSTORMS. FLASH FLOODING IS STILL A
POSSIBILITY...BUT FEEL THE SEVERITY OF THE STORMS IS LIMITED WITH
BOTH MARGINAL SHEAR /30-40 KT/ AND MID-LVL LAPSE RATES. THERE IS
STILL DECENT INSTABILITY THRU THE RGN...LIKELY TO BE FORCED BY THE
APPROACHING SHRTWV DISTURBANCE...FUELING MOISTURE THRU THE ATMOS
/PWATS ADVERTISED AROUND 2 INCHES DURING THIS TIMEFRAME/. 1-2 INCH
RAINFALL RATES AN HOUR WILL BE PSBL.
AFTER...EXPECTING ACTIVITY TO DIMINISH AS IT HAS DONE SO UPON
EXITING THE MID-ATLANTIC /DOWNWARD MOTION WITH NVA POST SHRTWV/.
NEVERTHELESS...CONTINUED STRONG LOW-LVL FLOW OVRNGT PER DECOUPLED
BOUNDARY LYR COULD RESULT IN CONTINUED ACTIVITY TO THE REAR...
ALBEIT SCT-ISOLATED. MDL FCST GUIDANCE SHIFTS TRAILING ACTIVITY
MAINLY OFFSHORE...AND THIS PATTERN IS SEEN PRESENTLY TAILING THE
MAIN IMPULSE IMPACTING LONG ISLAND. HAVE ADJUSTED TO CHC POPS THRU
THE INTERIOR...LIKELY ALONG THE S COASTLINE OUT ONTO THE CAPE.
&&
.SHORT TERM /9 PM THIS EVENING THROUGH 6 PM SATURDAY/...
TONIGHT...
SHRTWV DISTURBANCE EJECTS NWD OUT OF THE RGN. FEEL THE THREAT OF
HEAVY DOWNPOURS AND LOCALIZED FLOODING WILL DIMINISH AFTER 8 PM AS
THE BULK OF THE PRECIP ACROSS CENTRAL NEW ENGLAND LIFTS OUT.
ACTIVITY WILL CONTINUE THRU THE OVRNGT PD ALONG THE S/SE NEW ENGLAND
WHERE WITH BOUNDARY LYR DECOUPLING...LOW-LVL FLOW WILL ENHANCE TO
THE REAR OF THE DEPARTING SHRTWV /SWLY 30-40 KT/ JUST ABOVE THE SFC.
VERY MOIST TROPICAL LOW-MID LVL FLOW WILL ISENTROPICALLY LIFT WITHIN
A RGN OF FAVORABLE HEIGHT FALLS INVIGORATING FURTHER SHOWERS AND
THUNDERSTORMS. WHILE THIS ACTIVITY MAY REMAIN OFFSHORE...WILL KEEP
LIKELY POPS WITH THE SUSPICION OF ACTIVITY REDEVELOPING LATER
TONIGHT. BOTH 10/0Z AND 10/12Z CANADIAN INITIALIZED WELL WITH THE
MORNING ACTIVITY INTO THE MIDDAY-AFTN PD. AM LEANING FAVORABLE
TOWARDS ITS MDL FCST OUTPUT.
THEREFORE...FEEL THE THREAT OF HEAVY DOWNPOURS AND LOCALIZED
FLOODING WILL DIMINISH AFTER 8 PM AS THE BULK OF THE PRECIP ACROSS
CENTRAL NEW ENGLAND LIFTS OUT. CHC TO LIKELY SHOWERS AND
THUNDERSTORMS TO CONTINUALLY IMAPCT S/SE NEW ENGLAND COUPLED WITH
STRONG SLY ONSHORE FLOW WITH PSBL GUSTS OF 20-25 KTS. PWATS
ADVERTISED BY FCST GUIDANCE IS AROUND 2 INCHES FOR THIS TIMEFRAME.
FLOODING IS PSBL FOR COASTAL PLAIN LOCALES.
SHOULD BE A MILD NGT WITH MODEST SFC SLY FLOW AND CONTINUED HIGH
DWPTS IN THE LOW 70S.
SATURDAY...
INTO THE MORNING...ACTIVITY MAY STILL BE ONGOING ALONG S/SE NEW
ENGLAND. ATTENTION FOCUSES ACROSS INTERIOR NEW ENGLAND WHERE A
TROPICAL AIRMASS RESIDES...AND WITH PARTIAL CLEARING...ANTICIPATE
DESTABILIZING OF THE LOCAL ATMOS RESULTING IN THE DEVELOPMENT OF
SCTD SHOWERS AND THUNDERSTORMS ALONG AND AHEAD OF AN APPROACHING
COLD FRNT. LAPSE RATES ARE MARGINAL /STILL WITHIN THE WARM TONGUE
OF AIR WRAPPING AROUND THE UPR LVL LOW OVER THE ERN GRT LKS...
BETTER COLD AIR AND STEEP LAPSE RATES WILL BE WELL W/.
WITH PWATS ADVERTISED UP TO 2 INCHES...ONCE AGAIN THERE IS THE
THREAT WITH ANY STORMS THAT HEAVY DOWNPOURS WILL OCCUR RESULTING
IN LOCALIZED FLOODING. EXPECT MAX TEMPS INTO THE LOW-MID 80S WITH
MUGGY CONDITIONS.
&&
.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
* PRECIP COMES TO AN END WITH DRIER AIR MOVING IN SUN
* SHOWERS AND THUNDERSTORMS POSSIBLE MIDWEEK
OVERVIEW...
MODELS ARE IN EXCELLENT AGREEMENT THROUGH THE FIRST PART OF NEXT
WEEK. AFTER ABOUT TUESDAY...THERE STARTS TO BE SOME DISCREPANCIES
IN THE SYNOPTIC SCALE PATTERN BETWEEN THE GFS AND THE ECMWF. SO FOR
THE OVERALL PATTERN...SOUTHWEST FLOW WILL CONTINUE ACROSS SOUTHERN
NEW ENGLAND THROUGH THE FIRST PART OF THE WEEK...WITH THE UPPER LOW
OVER THE GREAT LAKES MOVING INTO NORTHERN ONTARIO. AT THE
SURFACE...LOW PRESSURE MOVES THROUGH SOUTHERN CANADA WITH A COLD
FRONT MOVING THROUGH SOUTHERN NEW ENGLAND ON SUNDAY. THIS IS
FOLLOWED BY WEAK HIGH PRESSURE MONDAY AND TUESDAY. MIDWEEK WE
EITHER STICK WITH THE SW FLOW WITH A NEW UPPER LOW MOVING INTO THE
GREAT LAKES AND THEN OVER SOUTHERN NEW ENGLAND LATER IN THE WEEK PER
THE GFS...OR WE TRANSITION TO A MORE WESTERLY FLOW WITH WEAK UPPER
LEVEL RIDGING PER THE ECMWF.
GIVEN THE TIME FRAME...AND THE SIMILARITIES IN THE SENSIBLE
WEATHER...WILL LIKELY USE A BLEND OF THE TWO MODELS WITH THE
PREVIOUS FORECAST FOR WEDNESDAY THROUGH THE END OF THE FORECAST
PERIOD.
SATURDAY NIGHT AND SUNDAY...SOUTHWEST FLOW CONTINUES OVER THE REGION
WITH THE NEARLY STACKED LOW MOVING NORTHEASTWARD INTO QUEBEC. THIS
WILL LEAD TO PRECIPITATION DIMINISHING FROM WEST TO EAST WITH RAIN
LINGERING ON THE CAPE SUNDAY AFTERNOON AND EVENING. EXPECT MOSTLY
CLOUDY SKIES...GRADUALLY CLEARING FROM WEST TO EAST ON SUNDAY.
TEMPERATURES WILL BE IN THE MID TO UPPER 80S ACROSS MOST OF THE
REGION.
MONDAY AND TUESDAY...THESE SHOULD BE THE QUIETER DAYS OF THE WEEK
WITH HIGH PRESSURE BUILDING INTO THE AREA. MOSTLY SUNNY SKIES
MONDAY AND TEMPERATURES IN THE LOW TO MID 80S. THEN INCREASING
CLOUDS ON TUESDAY WITH TEMPERATURES IN THE MID 80S.
WEDNESDAY THROUGH FRIDAY...AS STATED ABOVE THIS IS THE PERIOD OF
MOST UNCERTAINTY IN THE MODELS. REGARDLESS OF THE DIFFERENCES IN
THE SYNOPTIC LEVEL PATTERN...THE DETAILS ARE REMARKABLY SIMILAR WHEN
IT COMES TO THE SENSIBLE WEATHER. EXPECT SHOWERS AND THUNDERSTORMS
ON WEDNESDAY...WITH EITHER LOW PRESSURE AND A SURFACE TROF OVER THE
AREA PER THE ECMWF OR A MID LEVEL SHORTWAVE MOVING ACROSS THE AREA
PER THE GFS. EXPECT SHOWERS WILL BE MORE DIURNAL THURSDAY AND
FRIDAY...IF THERE IS ANY...WITH MID LEVEL RIDGING MOVING OVER SNE
PER ECMWF AND MID LEVEL SHORTWAVE DEPARTING THE AREA PER THE GFS.
EXPECT THINGS TO CHANGE AS WE GET CLOSER TO THIS TIME PERIOD.
