The episode as NWS PHI wrote it up.
A strong cold front associated with a low pressure system moving through New York State swept across the area during the late evening hours of April 2nd and early morning hours of April 3rd, accompanied by thunderstorms, very strong convectively driven winds, and small hail. As colder air behind this front drained south, precipitation changed to snow showers, with a coating reported in isolated spots in northern Delaware from squalls. The parent low pressure system then quickly intensified as it continued to move northeast away from the area. The gradient between this low pressure system and incoming high pressure produced strong winds gusting over 60 MPH in some localities from late overnight through the morning hours of April 3rd. Some reported peak wind gusts included: 51 MPH at Dover Air Force Base at 0515EST (Kent County), 62 MPH at Wilmington New Castle County Airport at 0728EST (New Castle County), and 48 MPH at Sussex County Airport at 0042EST (Sussex County).
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 Apr 2, 8:11 PM EST, 1 hour 54 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
911 PM EDT SAT APR 2 2016
.SYNOPSIS...
LOW PRESSURE TRACKING THROUGH THE GREAT LAKES AND INTO NEW ENGLAND
WILL LEAD TO A STRONG COLD FRONTAL PASSAGE ACROSS OUR AREA TONIGHT.
AN ALBERTA CLIPPER WILL MOVE ACROSS THE AREA MONDAY, FOLLOWED BY
HIGH PRESSURE LATER TUESDAY INTO WEDNESDAY. A COMPLEX AND STRONG
LOW PRESSURE SYSTEM WILL DEVELOP ALONG THE EAST COAST THURSDAY
INTO FRIDAY. HIGH PRESSURE MOVES INTO THE OHIO VALLEY SATURDAY.
&&
.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...
AN ARCTIC FRONT WILL APPROACH THE AREA FROM THE WEST THIS EVENING
BEFORE QUICKLY SWEEPING THROUGH THE AREA BETWEEN ABOUT 11 PM AND 2
AM. HI-RES MODELS CONTINUE TO ADVERTISE AN ORGANIZED LINE OF LOW-
TOPPED CONVECTION ALONG AND JUST AHEAD OF THIS FRONT. FORECAST
SOUNDINGS SHOW VERY STEEP LAPSE RATES THROUGHOUT THE TROPOSPHERE
WITH SEVERAL HUNDRED J/KG OF MUCAPE AVAILABLE FOR THIS CONVECTION
TO TAP INTO. A FEW EMBEDDED THUNDERSTORMS ARE CERTAINLY PLAUSIBLE.
ADDED THUNDER TO THE GRIDS WITH AN ENHANCED WORDING OF GUSTY WINDS
AND SMALL HAIL (THOUGH IT MAY BE GRAUPEL TOO).
THE HIGH WIND WARNING GOES INTO EFFECT AT MIDNIGHT TONIGHT AND
CONTINUES THROUGH NOON SUNDAY. THERE WILL BE A LARGE ISALLOBARIC
COMPONENT TO THE WIND FIELD ESPECIALLY OVER EASTERN PA AND NJ DURING
THE EARLY MORNING. THIS IS WHERE AND WHEN THE 12Z NAM AND GFS BOTH
INDICATE THE GREATEST PRESSURE RISES OF 9-12 MB IN 3 HOURS TO OCCUR
BEHIND THE DEEPENING LOW OVER NEW ENGLAND. AT THE SAME TIME, LAPSE
RATES WILL BECOME STEEP OWING TO THE IMPRESSIVE POST-FRONTAL
CAA...AND YIELD EFFICIENT DOWNWARD TRANSPORT OF STRONG WINDS ALOFT
TO THE SURFACE (EVEN WITHOUT THE AIDE OF SOLAR HEATING). THE
STRONGEST WINDS ALOFT ARE FORECAST TO BE FARTHER SOUTH ACROSS SE PA,
S NJ, DELMARVA (AROUND THE BACKSIDE OF THE LOW). BASED ON THE ABOVE,
WE ARE THINKING THE GREATEST POTENTIAL TO SEE 60 MPH WIND GUSTS AND
WIND DAMAGE WILL BE FROM ABOUT 3-9 AM AND ACROSS THE SOUTHERN TWO-
THIRDS OF THE CWA. WE ADDED SOME OF THESE DETAILS IN THE NPW.
ADDITIONALLY, THE FREEZE WATCH WAS UPGRADED TO A WARNING FOR THE
WESTERN SUBURBS OF PHILA AND WILMINGTON. INTERESTINGLY, AN
OVERWHELMING MAJORITY OF THE 12Z RAW NWP OUTPUT (IN ADDITION TO 60-
80 PERCENT OF 09Z SREF MEMBERS) PREDICT TEMPS FALLING BELOW FREEZING
AND EVEN INTO THE 20S WHILE MIN TEMPS FROM THE MAV AND MET MOS
GUIDANCE ARE IN THE MID 30S.
THERMAL PROFILES COOL QUICKLY OVERNIGHT AND RAIN SHOWERS WILL TURN
TO SNOW ACROSS NE PA AND NW NJ. SNOW SQUALLS BECOME A CONCERN ALONG
THE I-80 CORRIDOR LATE TONIGHT AND EARLY SUNDAY MORNING, ESPECIALLY
IN THE POCONOS. FORECAST SNOWFALL AMOUNTS WERE ADJUSTED UPWARD A BIT
WITH 1-2 INCHES EXPECTED IN OUR FAR NORTHERN ZONES ABOVE 1000 FT IN
ELEVATION. COULD NOT RULE OUT AN ISOLATED REPORT OF 3-4 INCHES AT
OUR HIGHEST RIDGES IN NORTHERN MONROE/CARBON COUNTIES IF A HEAVIER
STREAMER COMING OFF THE GREAT LAKES REACHES THE AREA.
IT WILL FEEL RATHER BRUTAL OUTSIDE DURING THE EARLY MORNING WITH
WIND CHILLS IN THE SINGLE DIGITS IN THE POCONOS, TEENS IN THE LEHIGH
VALLEY AND NW NJ, AND 20S ALONG THE I-95 CORRIDOR AND COASTAL
PLAIN.
CURRENT FCST LOOKS ON TRACK. THERE ARE A FEW LIGHTNING STRIKES,
BUT OTHERWISE, ITS GENERALLY RAIN SHOWERS. HOWEVER WILL KEEP SOME
T IN THE FCST, BUT CHC LOOK TO BE LOW. OTHERWISE, MADE SOME
ADJUSTMENTS TO TIMING AND POPS BASED ON LATEST RADAR TRENDS.
&&
.SHORT TERM /6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY/...
LOW PRESSURE WILL CONTINUE TO DEEPEN AS IT MOVES OFF INTO THE GULF
OF MAINE SUNDAY MORNING AND THEN INTO THE CANADIAN MARITIMES SUNDAY
AFTERNOON.
AS STATED IN THE NEAR TERM SECTION, THE STRONGEST WINDS (50-60 MPH
GUSTS) WILL OCCUR DURING THE EARLY MORNING. WINDS WILL GRADUALLY
WEAKEN OVER THE COURSE OF THE DAY.
COLD TEMPERATURES WILL BE A SHOCK TO THE SYSTEM SINCE WE JUST HAD
80F TEMPERATURES YESTERDAY. HIGHS TOMORROW WILL ONLY BE NEAR
FREEZING IN THE NE PA/NW NJ MOUNTAINS AND IN THE 40S ELSEWHERE BUT
THE BRISK WINDS WILL MAKE IT FEEL 10-20 DEGREES LOWER THAN THE
AMBIENT TEMPERATURE.
&&
.LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/...
AN AMPLIFIED MID-LEVEL FLOW WILL BE IN PLACE DURING THE SUNDAY NIGHT
THRU SATURDAY PORTION OF THE FORECAST. THIS CONTINUES AN ACTIVE
STRETCH OF WEATHER THROUGH THIS TIME FRAME.
SUNDAY NIGHT AND MONDAY...ANOTHER CLIPPER SYSTEM WILL BRING THE
POTENTIAL FOR SNOWFALL, MAINLY ACROSS FAR NORTHWEST NJ AND THE
POCONOS. THERE IS THE POTENTIAL FOR ADVISORY LEVEL SNOWFALL OVER THE
AFOREMENTIONED AREA /~ 3 INCHES/ BEFORE CHANGING OVER TO RAIN MONDAY
MORNING. HOWEVER, FORECAST AMOUNTS ARE JUST SHY OF ADVISORY
CRITERIA AT THIS TIME. FOR THE REMAINDER OF THE AREA, RAIN SHOWERS
ARE EXPECTED MONDAY AS THE CLIPPER SYSTEM MOVES THROUGH.
MONDAY NIGHT THRU WEDNESDAY...FAIR WEATHER AND CHILLY WITH CALENDAR
DAY AVERAGE TEMPERATURES 10-15 DEGREES BELOW AVERAGE. WITH THE
EXPECTED LOW TEMPERATURES AOB FREEZING AND GIVEN THE EARLY START TO
THE GROWING SEASON, FROST OR FREEZE WARNINGS MAY BE NEEDED TUE AND
WED MORNINGS. BREEZY CONDITIONS ARE ALSO EXPECTED MON NIGHT AND TUE
BEHIND THE DEPARTING CLIPPER SYSTEM. PATTERN RECOGNITION AND
COMPARISON TO RECENT EVENTS SUGGESTS THIS SHOULD BE FAIRLY BENIGN
WITH NORTHWEST WIND GUSTS UP TO AROUND 30 MPH. BUT WHEN COMBINED
WITH THE DRY AIR IN PLACE, FIRE WEATHER CONCERNS DURING THIS TIME
FRAME, WHICH WILL BE DEPENDENT ON FUEL MOISTURE.
WEDNESDAY NIGHT THRU SATURDAY...THE MID-LEVEL TROUGH OVER EASTERN
NOAM IS MODELED TO AMPLIFY, CULMINATING IN A CUT-OFF LOW OVER THE
NORTHEAST BY NEXT WEEKEND. AT THE SURFACE, A SLOW MOVING COLD FRONT
IS EXPECTED TO MOVE THRU THE REGION ON THURSDAY WITH A BRISK
SOUTHERLY FLOW PRECEDING IT. SOME HEAVIER RAINFALL IS POSSIBLE,
ESPECIALLY IF THUNDERSTORMS ARE ABLE TO DEVELOP. THURSDAY NIGHT INTO
FRIDAY, CYCLOGENISIS ALONG THE AFOREMENTIONED FRONT IS ANTICIPATED,
BUT MODEL SOLUTIONS DIVERGE FROM MAINE TO THE CAROLINAS. THERE IS
THE POTENTIAL FOR SNOWFALL, ESPECIALLY ACROSS THE HIGHER TERRAIN,
BUT THIS WILL BE DEPENDENT ON THE EVENTUAL TRACK AND EXTENT OF
PRECIPITATION, BOTH OF WHICH ARE HIGHLY UNCERTAIN AT THIS
JUNCTURE.
&&
.AVIATION /01Z SUNDAY THROUGH THURSDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY AND SURROUNDING AREAS.
GENLY VFR THRU THE TAF PD. KACY HAD SOME MVFR EARLIER AS THERE
WERE SOME LOW CLOUDS MOVG WWD FROM OFFSHORE. THEY ARE BACK TO VFR
NOW, BUT WITH THE CLOUDS NEARBY, CAN'T RULE OUT MORE MVFR OR IFR.
A STRONG COLD FRONT WILL MOVE THROUGH THE AREA SHORTLY AFTER
MIDNIGHT. AHEAD OF THE FRONT, A CONVECTIVE LINE OF SHOWERS WILL
SWEEP THRU THE REGION BETWEEN 03Z AND 06Z. THERE IS A POTENTIAL
FOR EMBEDDED THUNDER WITHIN IT BUT CONFIDENCE TOO LOW TO INCLUDE
IN TAFS RIGHT NOW. REGARDLESS, THIS CONVECTION HAS THE POTENTIAL
TO BRING DOWN GUSTY WLY WINDS OF 30-40 KT WITH IT. W-NW WINDS WILL
STRENGTHEN BEHIND THE FRONT TO AROUND 20-30 KT WITH GUSTS OF 45-50
KT DURING THE OVERNIGHT AND EARLY MORNING HOURS. WINDS GRADUALLY
SUBSIDE AFTER 12Z SUNDAY BUT WILL STILL BE GUSTING 30-40 KT IN THE
MORNING AND 25- 30 KT IN THE AFTERNOON.
OUTLOOK...
MVFR POSSIBLE IN LOWER CEILINGS AND SN/SHRA SUNDAY NIGHT AND
MONDAY. OTHERWISE, VFR THRU PERIOD.
&&
.MARINE...
A STRONG COLD FRONT APPROACHES FROM THE WEST THIS EVENING. THERE
WILL LIKELY BE A LINE OF SHOWERS AND ISOLATED LOW-TOPPED STORMS
AHEAD OF IT. THIS LINE WILL APPROACH THE DE BAY CLOSE TO 11 PM AND
ATLANTIC WATERS AT OR JUST AFTER MIDNIGHT. THERE IS A POTENTIAL
FOR GUSTY WLY WINDS OF 35-40 KT AND SMALL HAIL WITH THIS
CONVECTION. WINDS OVER ALL OF THE WATERS WILL INCREASE DRASTICALLY
BEHIND THE FRONT OVERNIGHT. THE STRONGEST WINDS WHEN STORM-FORCE
GUSTS UP TO 55 KT ARE EXPECTED IS FROM ABOUT 3-8 AM IN THE DE BAY
AND 4-10 AM IN COASTAL ATLANTIC WATERS OF NJ/DE.
OUTLOOK...
SCA FOR WINDS POSSIBLE IN THE SOUTHWEST FLOW AHEAD OF A COLD FRONT
MONDAY...BUT MORE LIKELY IN THE NORTHWEST FLOW BEHIND THIS FRONT
MONDAY NIGHT INTO TUESDAY. THE APPROACH OF ANOTHER COLD FRONT MAY
LEAD TO SCA SOUTHERLY WINDS WEDNESDAY NIGHT AND THURSDAY.
&&
.FIRE WEATHER...
AFTER COORDINATING WITH STATE FORESTRY OFFICIALS, WE WILL HOLD
OFF ON ISSUING A FIRE WEATHER WATCH FOR TOMORROW. OUR PARTNERS
FELT THE RAIN TODAY WAS WIDESPREAD AND HEAVY ENOUGH TO KEEP FUELS
MOIST ENOUGH TO POTENTIALLY LIMIT THE FIRE WEATHER THREAT. WE
PLAN ON COORDINATING AGAIN WITH THEM TOMORROW MORNING TO VERIFY
HOW FUELS HAVE RESPONDED.
FOR SUNDAY...NORTHWEST WINDS GUSTING TO 40-60 MPH WILL COMBINE
WITH AFTERNOON RELATIVE HUMIDITY VALUES DROPPING INTO 20S FOR A
TIME. THE EXCEPTION IS THE HIGHER ELEVATIONS OF NORTHEASTERN
PENNSYLVANIA AND FAR NORTHWESTERN NEW JERSEY, WHERE IT WILL BE
COLDER WITH A CHANCE OF SOME FLURRIES OR SNOW SHOWERS. AS STATED
ABOVE, A KEY QUESTION IS HOW RAPIDLY THE FUELS DRY OUT FOLLOWING
THE WIDESPREAD RAINFALL THIS MORNING. HOWEVER GIVEN THE EXTENT OF
THE WINDS, ANY FIRES COULD SPREAD QUICKLY WITH THIS BECOMING
ENHANCED IF THE FUELS ARE VERY DRY.
&&
.TIDES/COASTAL FLOODING...
WE'VE CHECKED A LOCAL REGRESSION EQUATION FOR BLOW OUT TIDE
POTENTIAL AT REEDY POINT DE FOR 230 AM SUNDAY AND 315 PM SUNDAY AS
WELL AS LEWES DE AT 11 AM SUNDAY. NEGATIVE DEPARTURES ARE LESS
THAN ETSS AND THE STEVENS MULTI MODEL OUTPUT AS WELL AS THE
STEVENS NYHOPS ENSEMBLE. THEREFORE, FOR NOW, BLOW OUT TIDES
EQUALING OR EXCEEDING -2.0 MLLW ARE NOT EXPECTED SUNDAY. (WE MAY
YET NEED TO REVISIT BASED ON THE REALITY OF THE WIND AND LOW TIDE
DEPARTURES COMING UP TONIGHT BUT FOR NOW THE CHANCE OF A BLOW OUT
TIDE EQUALING OR EXCEEDING -2.0 MLLW APPEARS TO BE LESS THAN 20
PERCENT WITH ONLY A COUPLE OF MODEL MEMBERS HIGHLIGHTING THE
POTENTIAL.
