Measured wind gusts included a 45 mph gust in Brandywine (New Castle County), and a 43 mph gust was recorded in Lewes (Sussex County) and also at Dewey Beach (Sussex County).

The episode as NWS PHI wrote it up.
An area of low pressure along the Middle Atlantic coast produced several strong easterly wind gusts during the morning of the 10th in Delaware. Measured wind gusts included a 45 mph gust in Brandywine (New Castle County), and a 43 mph gust was recorded in Lewes (Sussex County) and also at Dewey Beach (Sussex County). The low pressure slowly tracked along the Eastern Seaboard from around the Tidewater of Virginia early in the day, crossing the lower Delmarva Peninsula and eventually emerging off the southern New Jersey coast by the evening. In addition to some strong wind gusts, this coastal area of low pressure also produced rainfall amounts ranging mostly between 1.5 inches to 3.0 inches of rain in Delaware.

NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Nov 10, 4:01 AM EST, 2 hours 33 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
401 AM EST TUE NOV 10 2015
.SYNOPSIS...
THE SURFACE LOW WILL SLIDE UP THE EASTERN SEABOARD TODAY INTO
TONIGHT. HIGH PRESSURE FOLLOWS ON WEDNESDAY. THE NEXT LOW WILL LIFT
NORTHEAST THROUGH THE GREAT LAKES REGION LATE THIS WEEK, BRINGING A
PAIR OF COLD FRONTS TO OUR REGION, FIRST ON THURSDAY, THEN A
ANOTHER COLD FRONT ON SATURDAY. HIGH PRESSURE SHOULD SLOWLY BUILD
IN FROM THE WEST EARLY NEXT WEEK.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
AN AREA OF LOW PRESSURE CENTERED OVER EASTERN NORTH CAROLINA EARLY
THIS MORNING WILL GRADUALLY TRACK NORTHEASTWARD TODAY, EMERGING OFF
THE EASTERN SEABOARD AROUND THE VIRGINIA TIDEWATER AREA AROUND
DAYBREAK, THEN TRACKING JUST EAST OF THE DELMARVA PENINSULA AND THE
SOUTHERN NEW JERSEY COAST THIS AFTERNOON TO EARLY EVENING. LIGHT TO
MODERATE INTENSITY RAIN WILL PERSIST THIS MORNING, CONTINUING A
GRADUAL NORTHWARD PROGRESSION THROUGH OUR FORECAST AREA. EAST-
NORTHEAST WINDS WILL ALSO BE STEADILY PICKING UP, WITH SOME GUSTS
RANGING 15 TO 20MPH. SOMEWHAT STRONGER GUSTS ARE POSSIBLE FOR
EASTERN PARTS OF THE CWA, CLOSER TO 25 TO 30MPH, ESPECIALLY FOR THE
NORTHERN NEW JERSEY COAST. WE MAY THEN GET A BIT OF A LULL IN THE
STEADIER RAIN TOWARD THE MIDDLE OF THE DAY, BEFORE ANOTHER ROUND OF
STEADIER PRECIP AFFECTS THE AREA INTO LATE AFTERNOON TO EVENING
ASSOCIATED WITH A SHORTWAVE/VORT MAX PASSING OVER EASTERN
PENNSYLVANIA TO NORTHERN/CENTRAL NEW JERSEY. MOST LOCATIONS CAN
EXPECT RAINFALL AMOUNTS IN THE ONE-HALF TO THREE QUARTERS OF AN INCH
RANGE, BUT SOME AREAS COULD SEE AROUND AN INCH OF PRECIPITATION
THROUGH THIS EVENING. TEMPERATURES ARE EXPECTED TO RUN A FEW DEGREES
ABOVE AVERAGE, WITH HIGHS RANGING MOSTLY FROM THE MID 50S ACROSS THE
NORTH TO THE MID 60S INTO SOUTHERN NJ AND THE DELMARVA.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM WEDNESDAY/...
THE PREVIOUSLY MENTIONED UPPER-LEVEL SHORTWAVE/VORT MAX WILL BE
PASSING OVER NORTHERN PORTIONS OF THE FORECAST AREA THROUGH TONIGHT,
BRINGING ANOTHER ROUND OF STEADIER PRECIP TO MUCH OF OUR AREA.
MEANWHILE, THE COASTAL LOW PRESSURE WILL BE TRACKING NORTHEAST AND
AWAY FROM THE SOUTHERN NEW JERSEY COAST, ON ITS WAY TO THE SOUTHERN
NEW ENGLAND COASTAL WATERS BY EARLY WEDNESDAY. STEADIER RAIN WILL
GRADUALLY BE TAPERING OFF FROM SOUTH TO NORTH ACROSS THE FORECAST
AREA DURING THE EARLY MORNING HOURS, AND AS THE COASTAL LOW PRESSURE
PULLS AWAY, WINDS WILL TURN MORE NORTHERLY TO NORTH-NORTHWEST.
OVERNIGHT MINIMUM TEMPERATURES WERE A MET/MAV GUIDANCE BLEND WITH
CONTINUITY, WITH LOWS RANGING FROM THE MIDDLE 40S ACROSS THE NORTH
TO THE LOWER 50S INTO THE DELMARVA.
&&
.LONG TERM /WEDNESDAY THROUGH MONDAY/...
WEDNESDAY...UPPER LEVEL SHORT WAVE RIDGE SLIDES EAST TOWARDS THE
REGION. HOWEVER, CLOUD COVER WILL LIKELY LINGER THROUGH THE DAY,
SO WENT WITH THE LOWER SIDE OF GUIDANCE FOR HIGHS.
THURSDAY...THE NEXT LOW LIFTS INTO THE GREAT LAKES REGION.MODELS
CONTINUE TO SHOW A NEARLY VERTICALLY STACKED LOW. THUS, EXPECT A
BRIEF PERIOD OF PRECIPITATION WHILE THE REGION IS UNDER THE WARM
SECTOR IN RESPONSE TO THE APPROACHING MID AND UPPER LEVEL
VORTICITY MAX. ALSO, AT 250 MB THE REGION WILL BE UNDER THE LEFT
FRONT QUADRANT OF THE JET AT THAT LEVEL THROUGH THE DAY TIME
HOURS. PWAT VALUES COULD BE WELL ABOVE NORMAL, SO LEFT MENTION IN
THE HWO OF POTENTIAL FOR FLOODING IN POOR DRAINAGE AREAS.
HOWEVER...STORM MOTIONS WILL BE RELATIVELY FAST, AND THE PERIOD OF
OPPORTUNITY FOR PRECIPITATION WILL LIKELY BE BRIEF, SO FLOODING
THREAT IS SOMEWHAT LIMITED.
THURSDAY NIGHT THROUGH FRIDAY...COLD FRONT IS EXPECTED TO SWEEP
THROUGH THE REGION EARLY THURSDAY NIGHT BRINGING AN ABRUPT WIND
SHIFT AND AN ABRUPT END TO THE PRECIPITATION AS DRIER AIR FILTERS
INTO OUR REGION.
SATURDAY...A SECOND COLD FRONT MOVES THROUGH THE REGION. ALSO
THROUGH THIS TIME FLOW ALOFT TRANSITIONS TO MORE NORTHWESTERLY
WHICH COULD LEAD TO LAKE EFFECT PRECIPITATION TO OUR NORTHWEST.
HOWEVER, IT APPEARS UNLIKELY THAT THIS PRECIPITATION WILL MAKE IT
INTO OUR REGION GIVEN THE VERY DRY AIR THROUGH THE BOUNDARY LAYER
SUNDAY THROUGH TUESDAY...COULD SEE SOME MODEST AIR MASS
MODIFICATION AS A HIGH OVER THE SOUTHEAST TRIES TO BUILD INTO OUR
REGION, LEADING TO A MODEST WARMING TREND THROUGH THIS PERIOD.
&&
.AVIATION /08Z TUESDAY THROUGH SATURDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY, AND SURROUNDING AREAS.
TODAY...A CONTINUING TREND OF LOWERING CEILINGS AND VSBYS TO MVFR
LEVELS IS EXPECTED THROUGH THE EARLY MORNING AS RAIN CONTINUES TO
SLOWLY SPREAD FROM SOUTH TO NORTH THROUGH THE AREA. IFR CONDITIONS
ARE THEN ANTICIPATED WITHIN A COUPLE OF HOURS OF DAYBREAK FOR THE
TAF SITES AND ARE EXPECTED TO PERSIST THROUGH THE DAYTIME WITH SOME
PERIODS OF MORE MODERATE, STEADY RAINFALL PASSING ACROSS THE REGION.
OVERALL, EAST-NORTHEAST WINDS WILL CONTINUE EARLY AND THROUGH THE
DAYTIME, WITH GUSTS DURING THE DAY TO AROUND 20 KNOTS OR SO FOR THE
TAF SITES.
TONIGHT...MOSTLY IFR CONDITIONS WILL LIKELY CONTINUE THROUGH THE
FIRST PART OF THE NIGHT, WITH SOME IMPROVEMENT BACK TO MVFR
OVERNIGHT TO EARLY MORNING WEDNESDAY AS RAIN COVERAGE DECREASES
ACROSS THE AREA WITH LOW PRESSURE MOVING AWAY. SUSTAINED NORTHEAST
WINDS BETWEEN 10 TO 15 KNOTS WILL BECOME MORE NORTHERLY TO NORTH-
NORTHWEST OVERNIGHT.
OUTLOOK...
WEDNESDAY...MOSTLY VFR CONDITIONS EXPECTED. ON WEDNESDAY NIGHT THERE
IS A CHANCE FOR LOWER CLOUDS TO MOVE IN FROM THE WEST LEADING TO
MVFR CONDITIONS PRIMARILY AT KABE AND KRDG.
THURSDAY...FOR LOCATIONS THAT DO NOT SEE LOW CLOUDS WEDNESDAY NIGHT,
EXPECT MOSTLY VFR CONDITIONS WITH OCCASIONAL REDUCTIONS TO MVFR IN
RAIN SHOWERS. FOR TAF SITES THAT DO SEE CEILING REDUCTIONS WEDNESDAY
NIGHT, MVFR CEILINGS COULD LINGER THROUGH THE DAY WITH OCCASIONAL
REDUCTIONS IN VISIBILITY DUE TO RAIN SHOWERS.
FRIDAY...VFR CONDITIONS EXPECTED. GUSTY WESTERLY WINDS BEHIND THE
COLD FRONT (WITH GUSTS ABOVE 20 KT POSSIBLE).
SATURDAY...VFR CONDITIONS EXPECTED. GUSTY WESTERLY WINDS WITH GUSTS
ABOVE 20 KT POSSIBLE.
&&
.MARINE...
THROUGH TODAY EAST-NORTHEAST WIND GUSTS WILL BE INCREASING FOR OUR
ATLANTIC COASTAL WATERS AND INTO DELAWARE BAY AS A COASTAL LOW
PRESSURE SYSTEM TO OUR SOUTH GRADUALLY TRACKS NORTHEASTWARD. SMALL
CRAFT ADVISORY HEADLINES ARE IN PLACE AS GUSTS WILL REACH AROUND 30
KNOTS AT TIMES, WITH SEAS ALSO BUILDING THROUGH THE DAY. WHILE SOME
GUSTS COULD APPROACH GALE CRITERIA FOR OUR NORTHERN WATERS OFF THE
NJ COAST LATER THIS AFTERNOON TO EVENING, FORECAST SOUNDING DATA DID
NOT LEND ENOUGH CONFIDENCE TO ISSUE ANY GALE HEADLINES. THEREFORE,
SCA FLAGS WILL CONTINUE FOR OUR WATERS THROUGH THIS EVENING AND
TONIGHT, AS WINDS BECOME MORE NORTHERLY WITH TIME.
OUTLOOK...
WEDNESDAY...WINDS SHOULD DROP BELOW SCA CRITERIA BY MID DAY, BUT
WAVE HEIGHTS ABOVE 5 FT COULD LINGER FOR MUCH OF THE DAY. FOR NOW
HAVE KEPT THE EXPIRATION TIME OF THE SCA AT 11 AM DUE TO UNCERTAINTY
IN HOW QUICKLY THE WAVES WILL SUBSIDE.
THURSDAY THROUGH FRIDAY...SCA CONDITIONS ARE LIKELY, FIRST WITH
SOUTHERLY WINDS FOR MUCH OF THE DAY ON THURSDAY, THEN AN ABRUPT
SHIFT TO WESTERLY WINDS WITH A COLD FRONT THURSDAY NIGHT.
SATURDAY...SCA CONDITIONS ARE LIKELY. THERE IS A SMALL CHANCE FOR
GALE FORCE GUSTS AROUND 35 KT ON THE OCEAN WATERS THROUGH THE DAY.
&&
.TIDES/COASTAL FLOODING...
NEW MOON WILL BE WEDNESDAY LEADING TO ASTRONOMICAL HIGH TIDES
AROUND A FOOT BELOW MINOR FLOODING THRESHOLDS FOR BOTH THE
WEDNESDAY MORNING AND THURSDAY MORNING HIGH TIDE CYCLES. GUSTY
SOUTHERLY WINDS ARE EXPECTED TO DEVELOP EARLY IN THE DAY ON
THURSDAY. THUS THE HIGHEST RISK FOR ANY TIDAL FLOODING WOULD BE
WITH THE HIGH TIDE ON THURSDAY MORNING. ETSS GUIDANCE SUGGESTS
SOME OCEAN SIDE SITES COULD REACH MINOR FLOODING THRESHOLDS.
HOWEVER WE THINK THIS IS UNLIKELY ESPECIALLY CONSIDERING THE
LOCAL REGRESSION PROGRAM INDICATES TIDES SHOULD STAY BELOW
COASTAL FLOOD ADVISORY CRITERIA.
