The episode as NWS PHI wrote it up.
An intense low pressure that passed east of New Jersey on the 2nd combined with an approaching high pressure system to bring strong northwest winds into Eastern Pennsylvania mainly during the late morning and early afternoon of the 2nd. Peak wind gusts averaged 45 to 50 mph. The strong winds knocked down weak trees, tree limbs and wires and caused scattered power outages. This was particularly true in southeast Pennsylvania where many trees still had leaves on them as October was unseasonably warm. In Delaware County, a shed was tossed in Media and two vehicles were damaged by a downed tree in Havertown. In Philadelphia, newspaper dispensers were knocked over. About 22,600 homes and businesses lost power, 20,000 in PECO Energy's service area in southeastern Pennsylvania. Most of the outages were in Delaware and Montgomery Counties. The majority of customers had service restored the evening of the 2nd. The strong winds also caused arrival delays of about 90 minutes at Philadelphia International Airport.
Peak wind gusts included 50 mph in Bushkill Township (Northampton County), 49 mph in Lenhartsville (Berks County), 48 mph at the Philadelphia International Airport, 47 mph in Mount Pocono (Monroe County), 45 mph in West Chester (Chester County), 44 mph in Perkasie (Bucks County), 43 mph in Pottstown (Montgomery County) and 41 mph at the Lehigh Valley International Airport.
A developing low pressure over the Carolinas moved offshore on the morning of November 1st. As it passed east of Cape Hatteras, North Carolina during the early evening of November 1st, the pressure gradient (difference) between it and a high pressure system in the Mississippi Valley started to increase and winds became stronger. This pressure difference over Eastern Pennsylvania maximized during the late morning of the 2nd. At 7 a.m. EST on November 2nd, the low pressure system was well east of the New Jersey coast and as it reached the coastal waters east of Massachusetts that afternoon, strong winds ceased across Eastern Pennsylvania.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Nov 2, 7:53 AM EST, 7 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 753 AM EST SUN NOV 2 2014 .SYNOPSIS... STRONG LOW PRESSURE WILL CONTINUE TO MOVE INTO THE CANADIAN MARITIMES THROUGH TONIGHT. HIGH PRESSURE WILL BUILD TO OUR SOUTH MONDAY INTO EARLY TUESDAY, BEFORE MOVING OFFSHORE TUESDAY NIGHT AHEAD OF THE NEXT FRONTAL BOUNDARY EXPECTED EARLY WEDNESDAY. AN AREA OF LOW PRESSURE MAY DEVELOP ALONG THIS BOUNDARY TO OUR SOUTHWEST, THEN COMBINE WITH ANOTHER LOW MOVING IN FROM THE MIDWEST AND CREATE ANOTHER COASTAL STORM THURSDAY NIGHT INTO FRIDAY. HIGH PRESSURE IS THEN EXPECTED TO BUILD TO OUR SOUTH SATURDAY. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... THE BIG STORY TODAY WILL BE THE WINDS. FIRST THIS MORNING, THERE IS A THREAT THAT STRONGER WINDS FROM A LOW LEVEL JET COULD MIX DOWN SHORTLY AFTER SUNRISE UNTIL THE JET DIMINISHES BY ABOUT 15Z. KDIX DERIVED WINDS CURRENTLY SHOW WINDS AROUND 50KT ABOUT 3000 FT AGL. HOWEVER, FOR NOW HAVE CHOSEN NOT TO ISSUE A WIND ADVISORY AS CLOUD COVER WILL BE SLOW TO ERODE WHICH WILL HINDER ANY MORNING MIXING. WHILE A TIGHT PRESSURE GRADIENT WILL MEAN WINDY CONDITIONS WILL CONTINUE THROUGH THE DAY, THE OTHER PERIOD WHICH WILL BE WATCHED CLOSELY FOR APPROACHING WIND ADVISORY CONDITIONS WILL BE FROM 21Z THROUGH SUNSET THE HEIGHT GRADIENT IN THE MID AND UPPER LEVELS INCREASES. THROUGH THIS PERIOD MODEL SOUNDINGS SHOW A NEARLY DRY ADIABATIC LAPSE RATE THROUGH 850 MB SUGGESTING DEEPER MIXING. HOWEVER, THE LARGEST HEIGHT GRADIENTS ARE NOT EXPECTED UNTIL AFTER SUNSET AND THE PRESSURE GRADIENT WILL BE A BIT MORE RELAXED AFTER 18Z. THUS, DO NOT HAVE ENOUGH CONFIDENCE TO ISSUE A WIND ADVISORY FOR THIS PERIOD EITHER. AMPLE COLD AIR ADVECTION WILL CONTINUE TODAY. THUS, EXPECT HIGHS GENERALLY LOWER THAN YESTERDAY AND 10 TO 15 DEGREES BELOW NORMALS. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 AM MONDAY/... AS MENTIONED PREVIOUSLY, THE LARGEST MID AND UPPER LEVEL HEIGHT GRADIENTS ARE EXPECTED TO BE OVER THE REGION AFTER SUNSET THIS EVENING, BUT WITH A NOCTURNAL INVERSION, DO NOT EXPECT WIND ADVISORY CONDITIONS. INSTEAD, EXPECT THE BIG STORY TONIGHT TO BE TEMPERATURES WITH ALL OF THE REGION NEAR OR BELOW FREEZING, AND MUCH OF THE REGION LIKELY TO BOTTOM OUT IN THE 20S. SINCE GROWING SEASON HAS ENDED HOWEVER, NO FREEZE WARNINGS WILL BE ISSUED. && .LONG TERM /MONDAY THROUGH SATURDAY/... ON MONDAY AND MONDAY NIGHT, HIGH PRESSURE WILL BUILD TO OUR SOUTH AND NOSE ITS WAY NORTHWARD ACROSS OUR AREA. WITH LITTLE MOISTURE TO WORK WITH AS EVIDENT FROM PW VALUES 0.5 INCHES OR LESS, AND NO STRONG SHORT WAVE/VORTICITY IMPULSES IN THE NORTHWEST FLOW ALOFT, NO PRECIPITATION IS EXPECTED THROUGH MONDAY NIGHT. THERE MAY BE AN INCREASE IN CLOUDS LATE MONDAY INTO MONDAY NIGHT AS SOME MID-LEVEL MOISTURE SLIDES ACROSS THE AREA, OTHERWISE, DRY WEATHER WILL PREVAIL THROUGH MONDAY NIGHT. ON TUESDAY, THE HIGH PUSHES OFF THE SOUTHEAST COAST, SETTING UP A RETURN FLOW ACROSS THE AREA WHICH WILL ALLOW TEMPERATURES TO WARM AND AN INCREASE IN SURFACE DEWPOINTS. WE DO NOT EXPECT ANY PRECIPITATION THROUGH THE DAY TUESDAY AS PW VALUES REMAIN LOW AND STILL NO STRONG SHORT WAVE/VORTICITY IMPULSES ARE EXPECTED IN THE DEVELOPING SOUTHWEST FLOW ALOFT. AN INCREASE IN CLOUD COVER IS LIKELY, MAINLY LATER IN THE DAY TUESDAY. AS WE MOVE INTO TUESDAY NIGHT AND EARLY WEDNESDAY, A COLD FRONT IS EXPECTED TO APPROACH FROM THE WEST. MODELS ARE SHOWING THE PRECIPITATION DRYING OUT/DISSIPATING BEFORE IT REACHES OUR AREA, HOWEVER, THERE IS A SMALL CHANCE SOME ISOLATED/SCATTERED SHOWERS MAY MOVE INTO MOSTLY OUR NORTHWESTERN AREAS. THEN THINGS GET INTERESTING AGAIN. MEDIUM RANGE MODELS ARE NOW SLOWING DOWN THE FRONTAL BOUNDARY AS IT SAGS INTO OUR AREA WEDNESDAY, THEN DEVELOP AN AREA OF LOW PRESSURE TO OUR SOUTHWEST WEDNESDAY NIGHT ALONG THIS BOUNDARY. MEANWHILE, THEY MOVE ANOTHER LOW THROUGH THE MIDWEST TOWARD OUR AREA, BEFORE IT MERGES WITH THE AFOREMENTIONED LOW ALONG THE BOUNDARY INTO A STRONG COASTAL LOW THURSDAY NIGHT INTO FRIDAY. THERE'S GOOD AGREEMENT IN THIS OCCURRING, ALTHOUGH THERE IS SLIGHT TIMING AND PLACEMENT DIFFERENCES. THIS WOULD LEAD TO ANOTHER PERIOD OF HEAVY RAIN POTENTIAL, STRONG WINDS, AND COASTAL FLOODING. THIS WILL NEED TO BE WATCHED CLOSELY OVER THE NEXT FEW DAYS. THE LOW IS FORECAST TO CONTINUE TO LIFT TO OUR NORTH FRIDAY NIGHT INTO SATURDAY. A SHARP DROP IN TEMPERATURES WILL LIKELY OCCUR AGAIN BEHIND THIS SYSTEM, AND DEPENDING ON HOW FAST THE LOW LIFTS TO THE NORTH, THERE COULD BE A PERIOD OF RAIN CHANGING OVER TO SNOW FOR OUR HIGHER ELEVATIONS LATER ON FRIDAY INTO FRIDAY EVENING. SATURDAY IS EXPECTED TO BE PRECIPITATION FREE AS PW VALUES DROP BEHIND THE DEPARTING LOW, BUT WINDS WILL LIKELY REMAIN GUSTY THROUGH THE DAY. && .AVIATION /13Z SUNDAY THROUGH THURSDAY/... THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY AND SURROUNDING AREAS. FOR THE 12Z TAFS...VFR CONDITIONS WILL CONTINUE ACROSS THE REGION THROUGH THE TAF PERIOD. NORTHWESTERLY WINDS UP TO 25G35KT ARE EXPECTED ACROSS THE REGION TODAY. A FEW GUSTS TO 40KT CAN NOT BE RULED OUT ESPECIALLY THROUGH 15Z AND AGAIN BETWEEN 21 AND 00Z. WINDS WILL BE SLOW TO DIMINISH AFTER 00Z, BUT SHOULD SETTLE IN TO 10G20KT FOR MUCH OF THE OVERNIGHT HOURS. OUTLOOK... MONDAY-TUESDAY NIGHT ...VFR. WEST-NORTHWEST WIND GUSTS 15-20 KNOTS MONDAY AFTERNOON. WINDS DIMINISH AFTER SUNSET MONDAY. WEDNESDAY-WEDNESDAY NIGHT...VFR THROUGH THE DAY WITH INCREASING CLOUDS AND POSSIBLE SHOWERS OVERNIGHT WHICH MAY LEAD TO MVFR CONDITIONS OVERNIGHT. THURSDAY...DIMINISHING CONDITIONS WITH MVFR OR LOWER POSSIBLE, WITH PERIODS OF RAIN AND WINDY CONDITIONS ALSO POSSIBLE. && .MARINE... GALE CONDITIONS ARE EXPECTED TO CONTINUE THROUGH THIS EVENING AT LEAST. A FEW GALE GUSTS MAY OCCUR ON THE OCEAN WATERS AFTER MIDNIGHT, BUT WILL NOT EXTEND THE GALE WARNING AT THIS TIME UNTIL WE SEE HOW THE WINDS TODAY EVOLVE. EVEN AFTER WINDS DROP BELOW GALE CONDITIONS, BOTH WINDS AND SEAS ARE EXPECTED TO REMAIN IN SMALL CRAFT ADVISORY CONDITIONS FOR MUCH OF THE OVERNIGHT HOURS. OUTLOOK... MONDAY-MONDAY NIGHT...SMALL CRAFT ADVISORY LEVELS EARLY, THEN DROPPING BELOW ADVISORY LEVELS DURING THE DAY. TUESDAY-WEDNESDAY NIGHT...SUB SMALL CRAFT ADVISORY LEVEL CONDITIONS EXPECTED, ALTHOUGH WINDS MAY GUST NEAR 20 KNOTS AT TIMES. THURSDAY...INCREASING LIKELIHOOD OF AT LEAST SMALL CRAFT ADVISORY CONDITIONS AS LOW PRESSURE DEVELOPS TO OUR SOUTHWEST. && .TIDES/COASTAL FLOODING... THE WATER LEVELS ARE FALLING FOLLOWING HIGH TIDE, HOWEVER THE DEPARTURES STILL REMAIN ELEVATED. GIVEN THE STRONG OFFSHORE FLOW THOUGH TODAY, WE ARE ANTICIPATING THE RISK FOR MINOR COASTAL FLOODING TO GREATLY DECREASE BY THE NEXT HIGH TIDE CYCLE. THEREFORE, THE COASTAL FLOOD ADVISORY WAS ALLOWED TO EXPIRE. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...NONE. NJ...NONE. DE...NONE. MD...NONE.
