The strong pressure gradient (difference) between an intensifying strong low pressure system and a high pressure system in the Ohio Valley caused strong to high northwest winds to occur across Delaware from the evening of the 12th following a cold frontal passage through the daytime hours on the 13th. The highest winds occurred overnight on the 12th.

The episode as NWS PHI wrote it up.
The strong pressure gradient (difference) between an intensifying strong low pressure system and a high pressure system in the Ohio Valley caused strong to high northwest winds to occur across Delaware from the evening of the 12th following a cold frontal passage through the daytime hours on the 13th. The highest winds occurred overnight on the 12th. Peak wind gusts averaged 50 to 60 mph and knocked down weak tree limbs, trees and power lines. Scattered power outages occurred and affected the city of Wilmington. A pole fire occurred in Elsmere (New Castle County). Peak wind gusts included 62 mph in Lewes (Sussex County), 55 mph in Dewey Beach (Sussex County), 54 mph in Milton (Sussex County), 53 mph at the New Castle County Airport, 50 mph in Bellevue (New Castle County), 49 mph in Harrington (Kent County) and Dover (Kent County), 48 mph in Ellendale (Sussex County) and 46 mph in Newark (New Castle County).
The low pressure system responsible for the strong winds emerged from the Rockies on the evening of the 10th. It reached central Missouri on the evening of the 11th and western Pennsylvania on the afternoon of the 12th. It already was an intense 984 millibar low pressure system. The northeast moving 982 millibar low pressure system reached central New Jersey at 8 p.m. EDT on the 12th as its cold front was moving through Delaware. The 981 millibar low pressure system was near Boston, Massachusetts at 11 p.m. EDT on the 12th and reached Nova Scotia as a 976 millibar low pressure system at 5 a.m. EDT on the 13th. It continued to move northeast through the Canadian Maritimes during the day on the 13th and very slowly weakened. By evening on the 13th, the high pressure system was close enough to Delaware that the pressure gradient (difference) weakened and the strong winds stopped.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
711 PM EDT WED MAR 12 2014
.SYNOPSIS...
STRONG LOW PRESSURE WILL CONTINUE TO MOVE TO OUR NORTHEAST TONIGHT
PULLING A STRONG COLD FRONT ACROSS THE AREA THIS EVENING. HIGH
PRESSURE WILL BUILD TO OUR SOUTH THROUGH THURSDAY NIGHT AND FRIDAY.
A WARM FRONT MAY LIFT ACROSS THE AREA FRIDAY AS AN AREA OF LOW
PRESSURE MOVES THROUGH SOUTHEASTERN CANADA. A COLD FRONT ASSOCIATED
WITH THIS LOW WILL MOVE ACROSS THE AREA EARLY SATURDAY, FOLLOWED BY
ANOTHER EARLY SUNDAY. HIGH PRESSURE WILL TRY TO BUILD OUT OF SOUTH
CENTRAL CANADA AND DOWN ACROSS THE NORTHEAST LATE IN THE WEEKEND
INTO EARLY NEXT WEEK WHILE ANOTHER COASTAL STORM MAY DEVELOP OFF THE
SOUTHEAST COAST AND MOVE NEAR THE MID ATLANTIC REGION SUNDAY NIGHT
INTO MONDAY.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
A SEVERE THUNDERSTORM WATCH CONTINUES FOR PARTS OF THE FORECAST
AREA UNTIL 10PM THIS EVENING, INCLUDING FOR DELAWARE, THE EASTERN
SHORE OF MARYLAND, AND PORTIONS OF SOUTHERN NEW JERSEY. AS OF MID
EVENING, A RELATIVELY NARROW LINE OF SHOWERS WITH ASSOCIATED
STRONG WIND GUSTS UP TO AROUND 45MPH THUS FAR WAS TRACKING ACROSS
EASTERN PENNSYLVANIA AND INTO NORTHWEST NJ, WITH THE SOUTHERN EDGE
OF THIS LINE EXTENDING INTO NORTHERN DELAWARE AND FAR NORTHEAST
MARYLAND. THIS LINE OF SHOWERS WILL CONTINUE TO RACE EASTWARD AND
WILL LIKELY CLEAR MUCH OF THE REGION BY ABOUT 01Z. IN ITS WAKE,
STRONG AND GUSTY WINDS FROM THE NORTHWEST WILL CONTINUE THROUGH
LATE EVENING AND OVERNIGHT, WITH RAPIDLY FALLING TEMPERATURES.
SOME ADJUSTMENTS WERE MADE TO TEMPS/DEWPOINTS OVER THE NEXT FEW
HOURS, AS WELL AS TIMING OF THE LINE OF STRONG SHOWERS THROUGH THE
AREA, BUT OVERALL TONIGHTS FORECAST LOOKS IN LINE.
OTHERWISE, BAND OF SHOWERS MOVING THRU THE CWA NOW IN THE 23Z-
02Z TIME FRAME WITH POSSIBLE ISOLATED LOW TOPPED TSTM WITH THE
COLD FRONT. ML CAPE IS ALMOST NON EXISTENT BUT SHEAR IS LARGE AND
ITS A VERY DYNAMIC INTENSIFYING SYSTEM SO WE CANNOT RULE OUT A
GUST 50 KT WITH THE REMNANTS OF WHATEVER SQLINE PASSES THRU OUR
CWA EARLY THIS EVENING. PLS SEE SPC DISCUSSIONS AND FURTHER
UPDATES FROM OUR OFFICE THIS EVENING.
THE SPS CONTINUES WITH UPDATES FOR A RELATIVELY EXTREME CHANGE WITH
WIND DRIVEN COLD ARRIVING BY MIDNIGHT. 20 DEGREE DROPS FORESEEN IN
4 HRS.
IN ESSENCE... THE 12Z/12 NAM FOLLOWS SUIT FROM PRIOR MULTI MODEL
CONSENSUS. THAT MEANS WE DID NOT USE THE 12Z/12 MET MOS GUIDANCE
WHICH AT MIDNIGHT FOR PHL SHOWS A SFC TEMP OF 41F (5C) WHILE THE
12Z/12 NAM BL TEMP OF 14C AT 00Z/13 (MIGHT BE 2C TOO LOW? UNLESS
ITS RAINING AT 00Z) PLUNGES TO -7C AT 06Z (A DROP OF 21C OR 38F IN
6 HOURS). OUR PREVIOUS NUMBERS AND TREND REMAIN THE SAME AS
POSTED IN THE 330 AM FCST.
OTHERWISE...THE GUSTY SSW WINDS TO 25-35 MPH PHL AREA SOUTHWARD WILL
SHIFT NW THIS EVENING.
TONIGHT...COLD FRONT WILL SWEEP THROUGH THE REGION BETWEEN ROUGHLY
23Z AND 02Z WITH A PROBABLE 1 HR DELAY OF TEMPS FALLING SUBSTANTIALLY
AFTER THE WIND SHIFTS FROM SW TO NW. ANY REMAINING SEVERE RISK
WILL BE PRIMARILY OVER DELMARVA, FAR SE PA, AND S NJ AND THIS
SHOULD END NO LATER THAN 02Z.
WINDS: THE STRONGEST WINDS ON LAND ARE EXPECTED IN THE POCONOS,
WHERE TERRAIN EFFECTS WILL HELP MIXING, AND IN THE SOUTHERN HALF
OF THE CWA WHERE THE ISALLOBARIC WIND COMPONENT IS EXPECTED TO BE
THE STRONGEST. THE WIND ADVISORY CONTINUES AS POSTED EARLY THIS
MORNING. THERE IS RISK OF HIGH WIND WARNING CRITERIA FOR MDS
EASTERN SHORE AND DELAWARE WHERE THE COMBINATION 8 TO 10MB 3 HRLY
PRES RISES AND WINDS OF 45-50 KT DEVELOP DOWN TO NEAR 925 MB WITH
VERY STEEP LAPSE RATES DEVELOPING BY 03Z. AN UPGRADE MAY OCCUR
HERE NEAR 02Z IF UPSTREAM EVIDENCE SUPPORTS.
SNOW: NOT MUCH QPF EXPECTED AFTER 00Z AND SO SNOW ACCUMS WILL BE
MINIMAL IN THE FLASH FREEZE AREA OF MONROE COUNTY AND POSSIBLY
ELEVATED SUSSEX COUNTY NJ. FIRST IT HAS TO TURN COLD ENOUGH TO SNOW
AND THAT MAY NOT OCCUR IN MONROE AND SUSSEX COUNTIES TIL 9 OR 10 PM
WHEN MOST OF THE QPF HAS ENDED. STAY TUNED FOR UPDATES ON THIS SNOW
SECTION AS THIS IS A FINE LINE LINE BETWEEN LESS THAN ONE HALF INCH
SNOW AND 2 INCHES IN 2 HRS. OTHERWISE FLURRIES POSSIBLE OVERNIGHT
ELSEWHERE IN NJ AND PA
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH 6 PM THURSDAY/...
THURSDAY...BLUSTERY AND COLD WITH NW WIND GUSTS 35 TO NEAR 45 MPH AND
TEMPERATURES NEARLY 20 DEGREES COLDER THAN NORMAL, WIND CHILL VALUES
WILL REMAIN IN THE SINGLE DIGITS, POSSIBLY BELOW ZERO ACROSS THE
NORTHERN ZONES, FOR MOST OF THE DAY.
&&
.LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/...
FAIRLY GOOD AGREEMENT WITH THE LONG TERM MODELS FOR THE END OF
THE WEEK INTO THE WEEKEND, FOLLOWED BY SOME MODEL SPREAD AND LARGER
DIFFERENCES STARTING MONDAY INTO THE MIDDLE OF THE WEEK.
HIGH PRESSURE WILL BRIEFLY BUILD ACROSS THE AREA THURSDAY NIGHT THEN
WILL PUSH TO THE SOUTH OF THE AREA FRIDAY WHILE A WARM FRONT
LIFTS NORTH OF THE AREA. WE EXPECT DRY CONDITIONS THURSDAY NIGHT
INTO FRIDAY AS VERTICAL MOISTURE WILL BE LIMITED AND NO STRONG
SHORT WAVES/VORT MAXES ARE EXPECTED TO AFFECT THE AREA.
AS WE MOVE INTO FRIDAY NIGHT AND SATURDAY, A COLD FRONT WILL BE
APPROACHING THE AREA FROM THE WEST AS AN AREA OF LOW PRESSURE SWINGS
THROUGH SOUTHEASTERN CANADA. AGAIN, MOISTURE IS MOSTLY LACKING WITH
THE FRONTAL BOUNDARY, AND THE MAIN SHORT WAVE/VORT MAX IS EXPECTED
TO PASS NORTH OF THE AREA. SO FOR NOW WE DO NOT EXPECT MUCH
WIDESPREAD PRECIPITATION, ALTHOUGH THERE COULD BE ENOUGH FOR SOME
LIGHT SHOWERS TO AFFECT THE NORTHERN HALF OF THE AREA FRIDAY NIGHT
INTO SATURDAY MORNING. MODEL GUIDANCE HAS ANY PRECIPITATION
DISSIPATING AS IT MOVES INTO OUR AREA.
ANOTHER RELATIVELY DRY FRONTAL BOUNDARY IS EXPECTED OVERNIGHT
SATURDAY INTO SUNDAY MORNING, SO FOR NOW, WE WILL KEEP THE
WEATHER DRY FOR THIS PERIOD. HOWEVER, PRECIPITATING CHANCES
INCREASE ONCE LATER SUNDAY INTO MONDAY AS MODELS ARE INDICATING A
COASTAL STORM DEVELOPING AND MOVING NEAR THE MID-ATLANTIC COAST.
THERE ARE SOME TIMING AND PLACEMENT DIFFERENCES WITH ALL OF THE
MODEL GUIDANCE WHICH WOULD HAVE AN EFFECT ON PRECIPITATION CHANCES.
THE CANADIAN IS THE FARTHEST NORTHWEST, WITH THE ECMWF FARTHEST
OFFSHORE, AND THE GFS IN BETWEEN WITH THEIR RESPECTIVE
PRECIPITATION FIELDS. AS USUAL, THIS IS ALL DEPENDENT ON THE TRACK
OF THE LOW AND HOW FAR NORTHWEST THE MOISTURE PUSHES. FOR NOW WE
KEEP THE HIGHEST PROBABILITIES ACROSS THE SOUTHERN HALF OF THE
AREA FOR SUNDAY NIGHT INTO MONDAY. CANADIAN HIGH PRESSURE WILL BE
SLIDING TO OUR NORTH SUNDAY NIGHT INTO MONDAY, WHICH WILL USHER IN
COLDER AIR ACROSS THE AREA. THIS WOULD MAKE THE P-TYPE MOSTLY SNOW
FOR MUCH OF THE PERIOD.
PRECIPITATION CHANCES DIMINISH AS WE MOVE INTO MONDAY NIGHT AND
TUESDAY AS THE AFOREMENTIONED STORM MOVES TO OUR NORTHEAST AND HIGH
PRESSURE BRIEFLY BUILDS ACROSS THE AREA. THEN MODELS DIVERGE WITH
WHAT TO DO WITH THE NEXT POTENTIAL SYSTEM. FOR TUESDAY NIGHT INTO
WEDNESDAY, THE GFS BRINGS A LOW ACROSS SOUTHEASTERN CANADA, WHILE
THE ECMWF BRINGS A LOW RIGHT OVER OUR AREA. WITH THE SPREAD AND
UNCERTAINTY, WE FOLLOWED CLOSELY TO WPC WHICH IS SOMEWHERE IN
BETWEEN AND INTRODUCES CHANCE POPS ACROSS THE AREA AROUND WEDNESDAY.
&&
.AVIATION /00Z THURSDAY THROUGH MONDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.
REMAINDER OF TODAY...VFR CIGS WERE DEGRADING TO MVFR CONDS IN SHOWERS.
THERE IS A RISK FOR ISOLATED TSRA WITH A WEST GUST 30-40 KT BETWEEN
22Z AND 01Z NEAR THE COLD FRONTAL PASSAGE. OTHERWISE THE GRADIENT
SSW WIND GUSTS TO NEAR 25 KT KPHL REGION SOUTHWARD. LIGHT VARIABLE
MAINLY NE WINDS VCNTY KABE AND KRDG.
TONIGHT...THE COLD FRONT THIS EVENING WILL BRING AN ABRUPT WIND SHIFT
TO NW WITH GUSTS 34-44 KT. CONDITIONS SHOULD IMPROVE TO MAINLY VFR
CIGS AOA 3000 FT WITHIN A FEW HOURS OF THE WIND SHIFT TO NORTHWEST.
THURSDAY...VFR. GUSTY NORTHWEST WINDS 30 TO 38 KNOTS.
OUTLOOK...
THURSDAY NIGHT-FRIDAY...VFR. GUSTY SW 20-25 KT WINDS FRIDAY.
FRIDAY NIGHT-SATURDAY...MOSTLY VFR. SIGHT CHANCE OF RAIN OR SNOW
SHOWERS NORTH. GUSTY SW WINDS 20-25 KT SATURDAY.
SATURDAY NIGHT-SUNDAY...VFR. GUSTY NW WINDS 15-20 KT SUNDAY.
SUNDAY...VFR.
SUNDAY NIGHT-MONDAY...MVFR/IFR CONDITIONS POSSIBLE WITH SNOW
POSSIBLE FOR SOUTHEAST/COASTAL AREAS. MOSTLY VFR EXPECTED FOR
CENTRAL AND NORTHWESTERN TAFS OUTSIDE OF SNOW. GUSTY NE WINDS
20-25 KT.
&&
.MARINE...
GLW AND STW POSTED FOR TONIGHT. FUNNELING EFFECT OF DE BAY MAY
ASSIST IN GUSTY NW WINDS REACHING 50-55 KT FOR A TIME NEAR 06Z
TONIGHT.
NW GALES OF 35-40 KT THROUGH THE DAY THURSDAY AND SUBSIDE THURSDAY
EVENING.
OUTLOOK...
THURSDAY NIGHT...GALE WARNING CONTINUING EARLY, THEN DIMINISHING TO
SMALL CRAFT ADVISORY CONDITIONS OVERNIGHT.
FRIDAY-SATURDAY...CONDITIONS MAY DROP BELOW ADVISORY LEVELS EARLY,
THEN INCREASE TO ADVISORY CONDITIONS LATER IN THE DAY FRIDAY AND
CONTINUE INTO SATURDAY.
SATURDAY NIGHT-SUNDAY...CONDITIONS MAY DROP BELOW ADVISORY LEVELS,
BUT STILL REMAIN GUSTY AROUND 20 KT.
SUNDAY NIGHT-MONDAY...RETURN TO SMALL CRAFT ADVISORY CONDITIONS
POSSIBLE WITH POSSIBLE COASTAL LOW.
&&
.FIRE WEATHER...
AFTER COORDINATING WITH PARTNERS, WE WILL LIKELY ISSUE A FIRE
WEATHER SPS FOR THURSDAY OVERNIGHT TONIGHT/THURSDAY MORNING, AND
POSSIBLY ANOTHER FRIDAY MORNING FOR A PORTION OF THE AREA. AREAS
NORTH OF I-195 IN NEW JERSEY AS WELL AS EASTERN PENNSYLVANIA ARE
EXPECTED TO HAVE MOIST ENOUGH FUELS TO PRECLUDE THE NEED FOR ANY
SPS STATEMENTS. AREAS SOUTH OF I-195 IN NEW JERSEY AS WELL AS
DELAWARE AND THE EASTERN SHORE OF MARYLAND COULD BE DRY ENOUGH TO
ISSUE AN SPS FOR ENHANCED FIRE WEATHER CONCERNS AS IT WILL BE
QUITE WINDY THURSDAY AND RH VALUES LOWER CLOSE TO 30 PERCENT.
SIMILAR RH CONDITIONS MAY OCCUR ON FRIDAY, BUT WINDS ARE NOT
EXPECTED TO BE AS STRONG.
&&
.HYDROLOGY...
OPERATIONAL QPF AMOUNTS ARE NOT EXPECTED TO MAKE ANY OF OUR RIVERS
REACH FLOOD LEVELS, THERE WILL BE RISES DUE TO THE COMBINED RAINFALL
AND MELT OFF OF THE SNOW ACROSS THE NORTHERN HALF OF THE AREA.
WITH ANY THUNDERSTORMS LATE IN THE DAY, THERE COULD ALSO BE SOME
HEAVY RAINFALL THAT COULD PRODUCE URBAN AND POOR DRAINAGE TYPE
FLOODING.
SOMETHING TO KEEP AN EYE...PER THE HYDRO ENSEMBLES, WHICH ARE RUNNING
WITH MORE RAINFALL THAN OPERATIONAL SOLUTIONS, 1.00 TO 1.50 INCHES
OF BASIN-WIDE RAINFALL WOULD INCREASE THE FLOOD THREAT ACROSS THE
NORTHERN HALF OF THE HSA.
LUCKILY, WE DO HAVE SOME WIGGLE ROOM WITH 0.50 TO 0.75 INCHES IN THE
FORECAST.
