AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TAUNTON MA
150 PM EDT WED JUL 14 2010
.SYNOPSIS...
LOW PRESSURE TRACKING ALONG A WARM FRONT WILL BRING SHOWERS AND
SCATTERED THUNDERSTORMS TODAY. TYPICAL SUMMERTIME WEATHER WILL
THEN PREVAIL INTO THE WEEKEND. A COOL FRONT MAY BRING SCATTERED
SHOWERS AND THUNDERSTORMS FRIDAY AND SATURDAY.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
WARM FRONT HAS BEEN PUSHED BACK TO THE SOUTH COAST WITH NORTHEAST
WINDS ACROSS MUCH OF THE AREA...EXCLUDING THE IMMEDIATE SOUTH
COAST AND THE ISLANDS WHERE SOUTH WINDS PREVAIL. AREA OF SHOWERS
OVER SOUTHERN NEW ENGLAND HAS STARTED TO FILL BACK IN OVER THE
LAST HOUR OR SO WITH SOME STRONGER SHOWERS DEVELOPING OVER
NORTHEASTERN CONNECTICUT AND NORTHERN RHODE ISLAND. RAINFALL RATES
IN THESE STRONGER STORMS ARE ROUGHLY 1 INCH PER HOUR ON THE RADAR
ESTIMATED RAINFALL...HOWEVER...WITH PWAT VALUES STILL IN THE 2 TO
2.5 INCH RANGE...WOULD NOT BE SURPRISED TO SEE RAINFALL RATES UP
TO TWO TO THREE INCHES PER HOUR. ANOTHER AREA OF PRECIPITATION
OVER EASTERN PA...NJ...AND EXTREME SOUTHERN NYS HAS REMAINED
NEARLY STATIONARY OVER THE LAST COUPLE OF HOURS...RESULTING IN
SOME FLASH FLOODING THERE.
WE HAVE OPTED TO LEAVE THE FLASH FLOOD WATCH IN PLACE FOR THE TIME
BEING...PARTICULARLY SINCE THE MODELS ARE NOT HANDLING THIS
RAINFALL WELL. SEVERAL HAVE AT LEAST AN INCH OR TWO MORE OF RAIN
FALLING OVER THE AREA THIS AFTERNOON. WHILE WE HESITATE TO BUY
INTO THIS SOLUTION...GIVEN THEIR HANDLING OF THE PRECIP THUS
FAR...WE CANNOT COMPLETELY RULE IT OUT EITHER. OVERALL...WE HAVE
A VERY LOW CONFIDENCE FORECAST FOR THE REMAINDER OF THE AFTERNOON.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/...
SLOW IMPROVEMENT EXPECTED TONIGHT AS SYSTEM HEADS OFFSHORE...
THOUGH NE FLOW IN ITS WAKE SHOULD KEEP CLOUDS/FOG ALONG COAST.
HIGH PRESSURE BUILDS INTO REGION THU WITH CLEARING SKIES
THROUGHOUT.
&&
.LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/...
UPPER LOW PRESSURE MOVES ACROSS CANADA THIS WEEK...PASSING NORTH
OF NEW ENGLAND SATURDAY BEFORE GETTING ABSORBED INTO LABRADOR
UPPER LOW EARLY NEXT WEEK. WITH HIGH PRESSURE ENCAMPED OVER THE
SOUTHERN TWO-THIRDS OF THE USA...THIS BRINGS A GENERALLY ZONAL
FLOW TO THE NORTHERN TIER LATE THIS WEEK AND EARLY NEXT WEEK. AS A
CONSEQUENCE...NO MAJOR CHANGES IN TEMPERATURE OR HUMIDITY ARE
EXPECTED DURING THE PERIOD.
TWO COLD FRONTS...OR /ARGUABLY/ TWO REMNANTS OF COLD FRONTS MOVE
THROUGH NEW ENGLAND DURING THE PERIOD. THE FIRST CROSSES ON
SATURDAY AND EITHER MOVES OFFSHORE OR DISSIPATES SATURDAY NIGHT AS
THE UPPER LOW PASSES TO OUR NORTH AND THE UPPER FLOW BRIEFLY TURNS
NORTHWEST. THE FLOW THEN FLATTENS AGAIN AS A SHORTWAVE ROTATES
AROUND THE LABRADOR LOW...THIS SHORTWAVE SHOULD MOVE THROUGH LATE
MONDAY OR MONDAY NIGHT. THE FLOW AGAIN TURNS NORTHWEST AFTER THE
WAVE PASSES.
EACH FRONT HAS JET SUPPORT AS IT MOVES THROUGH...THE SATURDAY
FRONT SUPPORTED BY THE RIGHT ENTRANCE REGION OF A 85 KNOT JET AND
THE MONDAY FRONT BY THE LEFT EXIT REGION OF A 95 KNOT JET.
SUFFICIENT INSTABILITY AHEAD OF EACH FRONT TO SUPPORT CONVECTION.
PRECIPITABLE WATER VALUES WILL BE AROUND 2 INCHES FRIDAY
NIGHT/SATURDAY...AND 1.5 TO 2 INCHES ON MONDAY. SO BOTH SETS OF
CONVECTION SHOULD SUPPORT LOCALLY HEAVY DOWNPOURS.
AS NOTED BY THE PRIOR LONG TERM FORECASTER THIS ACTIVITY SHOULD BE
SCATTERED...SO MUCH OF THE TIME WILL BE RAINFREE. THE AIRMASS WILL
REMAIN VERY WARM AND VERY HUMID MUCH OF THE TIME. THERE MAY BE
BRIEF DRYING SATURDAY NIGHT AFTER THE FIRST PASSAGE...BUT WINDS
SHIFT BACK TO SOUTHWEST BY SUNDAY PUTTING US BACK IN THE SOUPY
AIR. WIND SHIFT TUESDAY MAY ALSO BRING MARGINALLY LOWER
DEWPOINTS...BUT VALUES SHOULD STILL LINGER AROUND 60-65.
TEMPS ALOFT REMAIN IN THE MID TO UPPER TEENS THROUGH THE PERIOD.
SO TEMPERATURES WILL HAVE A FULL MIXING POTENTIAL IN THE UPPER 80S
AND LOWER 90S...WITH THE EXTENT OF ANY CLOUD COVER DETERMINING
WHETHER EACH DAY REACHES ITS POTENTIAL. WE USED A BLEND OF MOS AND
HPC GUIDANCE...WITH MAX TEMPS IN THE UPPER 80S/LOW 90S LATE THIS
WEEK AND IN THE MID TO UPPER 80S EARLY NEXT WEEK. MIN TEMPS AND
DEWPOINTS SHOULD REMAIN IN THE UPPER 60S AND LOW 70S THROUGH
SATURDAY...AND IN THE 60S NEXT WEEK.
&&
.AVIATION /17Z WEDNESDAY THROUGH SUNDAY/...
THROUGH 00Z...LOW CONFIDENCE. WIDESPREAD MVFR/IFR EXPECTED AS RAIN
CONTINUES OR DEVELOPS ACROSS MUCH OF THE AREA THIS AFTERNOON. EVEN
IN AREAS WHERE RAIN DOES NOT DEVELOP...EXPECT LOW CLOUDS TO REMAIN
IN PLACE.
TONIGHT...HIGHER CONFIDENCE. MVFR CIGS WITH PATCHY FOG. IFR
EXPECTED ALONG COAST DUE TO ONSHORE FLOW.
THU...HIGH CONFIDENCE. IMPROVEMENT TO VFR BY MID MORNING...BUT
MVFR MAY LINGER AROUND CAPE COD AND ISLANDS INTO THU AFTERNOON.
KBOS...LOW CONFIDENCE EARLY BUILDING TO MEDIUM CONFIDENCE LATE
TONIGHT. LOW PROBABILITY OF A THUNDERSTORM LATER THIS AFTERNOON.
RAIN SHOWERS MAY MOVE THROUGH AND DISSIPATE THROUGH THE AFTERNOON.
