AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
1248 AM EDT WED OCT 31 2012
.SYNOPSIS...
WEAKENING LOW PRESSURE OVER THE EASTERN GREAT LAKES WILL GRADUALLY
MOVE INTO QUEBEC TONIGHT AND THURSDAY. MEANWHILE, HIGH PRESSURE
FROM CENTRAL CANADA WILL SPREAD SOUTHWARD INTO THE MIDWEST STATES
AND EVENTUALLY INTO THE MID ATLANTIC REGION OVER THE WEEKEND. THE
NEXT LOW PRESSURE SYSTEM WILL APPROACH THE REGION FROM THE
SOUTHWEST BY MONDAY.
&&
.NEAR TERM /UNTIL 8 AM THIS MORNING/...
MAY BE CANCELING MOST OF THE REST OF THE COASTAL FLOOD ADVISORIES
DURING THE NIGHT WITH ONLY CAMBRIDGE THE PRIMARY RISK SENSOR
RELATED COUNTIES.
BANDS OF MAINLY LIGHT RAIN CONTINUE TO DRIFT NORTH AHEAD OF MID
LEVEL SHORT WAVES ROTATING THROUGH BROAD CYCLONIC FLOW CENTERED
OVER WESTERN PENNSYLVANIA.
THE COLUMN IS IN THE PROCESS OF COOLING FROM SOUTH TO NORTH...AS
SEEN ON THE KIAD SOUNDING. THIS RAISES AN INTERESTING PRECIPITATION
TYPE ISSUE.
THE COLUMN DOES NOT YET APPEAR TO BE COLD ENOUGH TO ALLOW SUPPORT
SNOW REACHING MUCH BELOW THE FREEZING LEVEL NEAR 3500 FEET ACROSS
NORTHWEST AREAS. THE DUAL POL PRODUCTS INDICATE SNOW IN THE COLUMN
THROUGH ABOUT 4000 FEET. AS HEIGHTS DROP WITH THE APPROACH OF THE
SHORT WAVE...A WINDOW OF OPPORTUNITY FOR THE COLUMN TO COOL JUST
ENOUGH TO SUPPORT A FEW SNOWFLAKES IN THE HIGHEST TERRAIN COULD
OPEN. 1800 UTC NAM MODEL SOUNDINGS SUPPORT THIS IN THE SOUTHERN
POCONOS...WHERE THE COLUMN IS A BIT COOLER THAN NEARBY NORTHWEST
NEW JERSEY.
THERE IS A SMALL AMOUNT OF WET BULB COOLING AVAILABLE...SO A MIX
OF LIGHT RAIN AND SNOW HAS BEEN INTRODUCED IN ELEVATIONS ABOVE
1600 FEET (WHERE THE FREEZING LEVEL SHOULD LIE AFTER 0500 UTC. IT
IS POSSIBLE THAT ONLY THE HIGHEST TERRAIN SEES THE POTENTIAL...AND
THE MIX WAS PLACED ABOVE 1600 FEET.
ELSEWHERE...AS THE COLUMN COOLS...LOWS COULD EASE BACK INTO THE
UPPER 30S ACROSS THE LEHIGH VALLEY...AND TEMPERATURES THERE WERE
BACKED DOWN A BIT TO ACCOMMODATE. ELSEWHERE...LOW TEMPERATURES
LOOKED OK BASED ON TRENDS.
&&
.SHORT TERM /8 AM THIS MORNING THROUGH 6 AM THURSDAY/...
EX-SANDY CIRCULATION IS FCST TO MOVE NEWD ON WEDNESDAY RESULTING IN
WINDS SHIFTING FROM S TO SW BUT REMAINING RATHER LIGHT. CLOUDS AND
MOISTURE ASSOCD WITH THE CIRCLN WILL CONTINUE TO AFFECT THE AREA
ALTHOUGH THERE SHOULD BE A PARTIAL CLEARING TREND FROM THE SOUTH IN
THE AFTN. THERE IS NO ORGANIZED UVV TO PRODUCE PCPN SO POPS ARE LOW
EXCEPT FOR CHC IN THE POCONOS...LEHIGH VALLEY AND NW NJ. CLOUD
COVER WILL LIMIT HEATING BUT PARTIAL CLEARING SOUTH WOULD ALLOW
FOR TEMPS A FEW DEGS WARMER THAN TODAY.
WED NIGHT...PARTLY CLOUDY TO CLOUDY WITH MID LVL CIGS IN THE
LEFTOVER CYCLONIC CIRCULATION. LIGHT SW WIND.
TEMPS/DEWS/WINDS A 50 50 BLEND OF THE 00Z/31 NAM/GFS MOS GUIDANCE.
&&
.LONG TERM /THURSDAY THROUGH TUESDAY/...
AT THE START OF THE LONG TERM, LOW PRESSURE ASSOCIATED WITH THE
REMNANTS OF SANDY WILL CONTINUE TO SLOWLY PROGRESS NORTH NORTHEAST
FROM WESTERN NEW YORK STATE INTO SOUTHERN CANADA FROM WEDNESDAY
NIGHT THROUGH FRIDAY. THE BROAD CYCLONIC FLOW AROUND THIS LOW
PRESSURE WILL CONTINUE TO YIELD THE POSSIBILITY FOR A FEW SHOWERS
MAINLY ACROSS OUR NORTHWEST ZONES, AND WE HAVE RETAINED SLIGHT
CHANCE OR CHANCE POPS WITH THIS IN MIND. MAINLY WESTERLY WINDS ARE
EXPECTED FOR THE AREA THROUGH THE END OF THE WEEK, AND TEMPERATURES
WILL BE RUNNING NEAR TO SLIGHTLY BELOW AVERAGE WITH MAXIMUM TEMPS
RANGING FROM THE MIDDLE AND UPPER 40S IN THE SOUTHERN POCONOS TO THE
MIDDLE 50S ACROSS THE DELMARVA.
THROUGH THE END OF THE WEEK, AN AREA OF HIGH PRESSURE WILL GRADUALLY
BUILD SOUTHWARD FROM CENTRAL CANADA AND INTO THE MIDWESTERN STATES.
BY THE WEEKEND, THIS HIGH PRESSURE WILL SPREAD EASTWARD AND
INFLUENCE OUR REGION. DRY WEATHER WITH AMPLE SUNSHINE AND TEMPS
RUNNING NEAR OR SLIGHTLY UNDER SEASONAL NORMALS IS EXPECTED. TEMPS
WERE A BLEND OF HPC GUIDANCE WITH CONTINUITY.
FROM LATE SATURDAY THROUGH SUNDAY, THE GFS AND EURO SHOW AN AREA OF
SURFACE LOW PRESSURE ORGANIZING AROUND THE LOWER OHIO VALLEY REGION
AND GRADUALLY PROGRESSING EAST-NORTHEAST TOWARD THE MID ATLANTIC
REGION BY LATE SUNDAY INTO MONDAY. OVERALL THROUGH MONDAY, THE EURO
KEEPS THE PROGRESSION OF THIS LOW PRESSURE A LITTLE FARTHER SOUTH
THAN THE GFS, AND OVERALL THE SYSTEM LOOKS A LITTLE LESS ORGANIZED.
BY MONDAY NIGHT INTO TUESDAY, THIS LOW PRESSURE IS PROGGED TO MOVE
EAST AND OFF THE MID ATLANTIC COAST. AS THIS LOW PRESSURE MOVES
MAINLY SOUTH OF OUR AREA AND THEN OFF THE COAST, SOME SHOWERS ARE
EXPECTED WITH SLIGHT CHANCE TO LOW CHANCE POPS FOR NOW IN THE FCST
AT THIS EXTENDED TIMEFRAME.
&&
.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.
OVERNIGHT...VFR TO MVFR CIGS CONTINUE WITH BANDS OF LIGHT SHOWERS.
LIGHT SOUTH WIND.
WEDNESDAY...MVFR CONDITIONS SHOULD GIVE WAY TO VFR BKN CIGS BETWEEN
1400 UTC AND 1700 UTC AS THE LOW LEVEL INVERSION EASES. SOUTH
SOUTHWEST WINDS G10-15 KNOTS ARE EXPECTED IN THE AFTERNOON.
WED NIGHT...VFR WITH SCT CLOUDS TO BKN CIGS NEAR 9000 FT. LIGHT
SW WIND.
OUTLOOK...
WEDNESDAY NIGHT THROUGH FRIDAY...MAINLY VFR CONDITIONS EXPECTED.
POSSIBLE SHOWERS FOR AREAS NORTH AND WEST COULD BRIEFLY LOWER
CEILINGS AND/OR VSBYS.
FRIDAY NIGHT THROUGH SUNDAY...VFR CONDITIONS.
&&
.MARINE...
SCA PROBABLY TRIMMING TO SCA HAZARDOUS SEAS AT 330AM AND MAY EXTEND
THROUGH TONIGHT ON THE ATLC WATERS WHILE CONTINUING NO HEADLINE
FOR DE BAY IN THIS SHORT TERM FCST PERIOD.
OUTLOOK...
OVERALL, CONDITIONS WILL CONTINUE TO IMPROVE FOR OUR WATERS. BY
WEDNESDAY NIGHT, WIND GUSTS ARE EXPECTED TO DECREASE BELOW SCA
LEVELS, BUT SEAS WILL STILL BE EXCEEDING SCA CRITERIA. BY THURSDAY
NIGHT, SEAS ARE EXPECTED TO DIMINISH BELOW SCA. THE NEXT MAIN
TIMEFRAME FOR POTENTIAL SCA CONDITIONS WILL BE FROM FRIDAY NIGHT
THROUGH THE WEEKEND AS WIND GUSTS WILL BE AROUND THE SCA THRESHOLD.
&&
.TIDES/COASTAL FLOODING...
CFW AT 1113 PM EXPIRED NJ/DE COASTS. ANY WATER SEEN IN NJ I THINK
WOULD HAVE TO BE RELATED TO BEING TRAPPED BEHIND BARRIERS. AM THINKING
OF CANCELING THE TIDAL DELAWARE AT 1AM BASED ON A LAST CHECK OF
RP AND PHL SENSOR TRENDS. VERY LITTLE CHC FOR FLOODING ON RP
RELATED COUNTIES. SENSOR TRACE TRENDS ARE NOT FAVORING ANY SORT
OF TIDAL FLOODING THERE AND ONLY CAMBRIDGE ON THE CHESAPEAKE IS
THE REMAINING SOLID OPTION FOR MINOR AT WORST OVERNIGHT. MORE
CANCELLATION STATEMENTS MAY ENSUE BETWEEN 1245 AM AND 3 AM.
