The pressure gradient (difference) between an intensifying low pressure system that moved northeast through the Saint Lawrence River Valley and a high pressure system building into Delaware from the southwest produced strong west winds during the day on the 17th. This was in addition to the strong to severe thunderstorms that moved through the state during the early morning of the 17th.

The episode as NWS PHI wrote it up.
The pressure gradient (difference) between an intensifying low pressure system that moved northeast through the Saint Lawrence River Valley and a high pressure system building into Delaware from the southwest produced strong west winds during the day on the 17th. This was in addition to the strong to severe thunderstorms that moved through the state during the early morning of the 17th. Daytime peak wind gusts averaged around 45 mph and tore down weak tree limbs.
The calendar day peak winds (some of these occurred during the early morning thunderstorms) included 56 mph in Dover (Kent County), 50 mph in Lewes (Sussex County) and 40 mph at the New Castle County Airport.

NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Nov 17, 8:40 AM EST, 20 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
840 AM EST WED NOV 17 2010
.SYNOPSIS...
LOW PRESSURE TRACKING THROUGH EASTERN CANADA WILL QUICKLY PUSH A
COLD FRONT ACROSS OUR AREA EARLY THIS MORNING. BEHIND THIS COLD
FRONT, HIGH PRESSURE WILL GRADUALLY BUILD IN THIS AFTERNOON AND
EVENING. AS THIS HIGH SETTLES TO OUR SOUTH TONIGHT AND THURSDAY,
A SECONDARY COLD FRONT WILL CROSS OUR AREA THURSDAY EVENING. HIGH
PRESSURE WILL SETTLE IN DURING FRIDAY, THEN BECOME NEARLY
STATIONARY OVER THE SOUTHEASTERN UNITED STATES LATE FRIDAY AND
DURING THE WEEKEND. A WEAK FRONTAL BOUNDARY HOWEVER SHOULD SETTLE
SOUTHWARD ACROSS OUR AREA LATE SATURDAY BEFORE MOVING BACK
NORTHWARD AS A WARM FRONT LATE SUNDAY AND MONDAY.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
THE COLD FRONT, CURRENTLY CROSSING OUR AREA, WILL MOVE RAPIDLY OFF
TO THE EAST THIS AFTERNOON. SHOWERS HAVE ALL BUT ENDED OVER OUR
AREA AND SKIES HAVE CLEARED IN THE SOUTH AND EAST. THERE ARE STILL
A FEW LIGHT SHOWERS IN THE EXTREME NORTH. THESE WILL BE ENDING
BY MID MORNING. CLOUDS ARE PUSHING BACK IN FROM THE WEST NORTHWEST.
THIS WILL LEAVE US WITH PARTLY SUNNY CONDITIONS NORTH AND WEST AND
MOSTLY SUNNY SOUTH AND EAST FOR THE REMAINDER OF THE DAY.
WE THEN TURN TO OUR ATTENTION TO THE SYNOPTIC SCALE WINDS. AS THE
CAA DEVELOPS DURING THE DAY, A TIGHT PRESSURE GRADIENT WILL BE IN
PLACE WITH THE SURFACE LOW TO THE NORTH AND HIGH PRESSURE BUILDING
INTO THE OHIO VALLEY. THE FORECAST SOUNDINGS INDICATE AROUND 45
KNOTS OF WIND AT THE TOP OF THE MIXED LAYER. AS THE LOW-LEVEL
LAPSE RATES STEEPEN DURING THE COURSE OF THE DAY, THE VERTICAL
MIXING IS EXPECTED TO BECOME MORE EFFICIENT. BASED ON THIS, WE
WILL MAINTAIN THE WIND ADVISORY THAT WAS ALREADY ISSUED BUT EXPAND
IT TO INCLUDE THE ENTIRE CWA. ACROSS THE DELMARVA AREA, THE WIND
ADVISORY MAY BE MORE MARGINAL BUT SOME OF THE FORECAST SOUNDINGS
INDICATE A WINDOW OF OPPORTUNITY LATER THIS MORNING AND EARLY THIS
AFTERNOON WHERE THE WINDS COULD BE RIGHT AROUND ADVISORY CRITERIA.
THEREFORE AFTER COLLABORATION WITH WFO STERLING, VIRGINIA, WE
EXPANDED THE ADVISORY TO INCLUDE THE ENTIRE AREA.
AS FOR TEMPERATURES, WE GENERALLY TOOK A BLEND OF THE GFS/NAM MOS
BUT DID ADJUST UPWARD TO ACCOUNT FOR THE MILDER AIR IN PLACE EARLY
THIS MORNING. FOR MOST, THE HIGHS MAY ACTUALLY OCCUR THIS MORNING
ALTHOUGH THERE COULD BE SOME RECOVERY THIS AFTERNOON DESPITE THE CAA
GIVEN INCREASING SUNSHINE AND DEEPER MIXING.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY/...
A STRONG AREA OF LOW PRESSURE WILL BE MOVING INTO THE CANADIAN
MARITIMES TONIGHT. MEANWHILE, HIGH PRESSURE WILL BE BUILDING INTO
THE SOUTHEASTERN UNITED STATES. THE PRESSURE GRADIENT BETWEEN THESE
TWO SYSTEMS WILL REMAIN TIGHTENED ACROSS OUR AREA THIS EVENING, BUT
THEN RELAX THROUGH THE NIGHT AS THE SURFACE LOW MOVES FARTHER AWAY.
DESPITE A RATHER ROBUST WIND FIELD TO LINGER THROUGH AT LEAST THE
FIRST HALF OF THE NIGHT, THE FORECAST SOUNDINGS INDICATE THAT THE
LOW-LEVEL LAPSE RATES WEAKEN AS LOW-LEVEL COOLING TAKES PLACE. THIS
DECREASES THE VERTICAL MIXING SUBSTANTIALLY DURING THE EVENING
HOURS. AS A RESULT, WE WILL MAINTAIN THE WIND ADVISORY UNTIL 01Z. IF
CONDITIONS DROP BELOW ADVISORY CRITERIA THEN THE ADVISORY CAN BE
TAKEN DOWN EARLIER.
OTHERWISE, THE UPPER-LEVEL TROUGH LIFTS OUT OF THE AREA TONIGHT AS A
STRONG SHORT WAVE ROUNDS ITS BASE AND CLIPS OUR NORTHERN AREAS. EVEN
THOUGH THE AIRMASS IS DRYING OUT, THERE MAY BE SOME BANDS OF
STRATOCUMULUS DURING THE NIGHT WITHIN THE CAA REGIME. THIS MAY
ESPECIALLY BE TRUE ACROSS THE NORTHERN PORTIONS OF THE CWA, CLOSER
TO THE SHORT WAVE. THERE SHOULD BE ENOUGH WIND AT THE SURFACE TO
KEEP TEMPERATURES FROM REALLY BOTTOMING OUT.
FOR THURSDAY, CLOUDS ARE EXPECTED TO BE ON THE INCREASE AS AN
UPPER-LEVEL TROUGH AND SHORT WAVE MOVE INTO THE AREA. AT THE
SURFACE, A SECONDARY COLD FRONT IS EXPECTED TO CROSS THE AREA LATE
IN THE DAY. THE AIRMASS IS FORECAST TO BE GETTING COLDER THROUGH THE
DAY ESPECIALLY ABOVE THE SURFACE /500 MB TEMPERATURES DOWN AROUND
-25C/. THE FORECAST SOUNDINGS INDICATE THAT THE CONVECTIVE
TEMPERATURES SHOULD BE REACHED, ALLOWING CUMULUS TO DEVELOP AND
BECOME MORE VERTICAL. THERE DOES NOT APPEAR TO BE STRONG SYNOPTIC
FORCING OVERALL, HOWEVER ISOLATED TO SCATTERED SHOWERS CANNOT BE
RULED OUT IN THE AFTERNOON AND EARLY EVENING ESPECIALLY ACROSS THE
CENTRAL AND NORTHERN ZONES.
FOR FRIDAY, HIGH PRESSURE BUILDS IN FROM THE WEST AS SOME
UPPER-LEVEL RIDGING ARRIVES. AS THIS OCCURS, THE CAA DWINDLES AND
TURNS INTO WAA BY LATE IN THE DAY AS A STORM TRACKS ACROSS THE UPPER
GREAT LAKES REGION. THIS MAY ALLOW FOR SOME MID TO HIGH LEVEL CLOUDS
TO ARRIVE ACROSS OUR AREA ESPECIALLY ACROSS THE NORTHERN ZONES.
FOR TEMPERATURES, WE MAINLY TOOK AN EVEN BLEND OF THE GFS/NAM MOS.
&&
.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
OVERALL, FAIR WEATHER WILL BE ACROSS THE MIDDLE ATLANTIC REGION THIS
WEEKEND AS A SURFACE HIGH PRESSURE SYSTEM WILL BE IN CONTROL.
HOWEVER, A WEAK FRONT LOOKS TO SETTLE SOUTHWARD ACROSS OUR CWA LATE
SATURDAY BEFORE TURNING BACK NORTHWARD AS A WARM FRONT. A SURFACE
LOW WILL BE MOVING ACROSS SOUTHERN CANADA, SO A WARM SOUTHWEST FLOW
WILL DEVELOP ACROSS THE REGION.
A STORM TRACK LYING ACROSS THE SOUTHERN PLAINS INTO THE GREAT LAKES
WILL SEND A LOW PRESSURE SYSTEM NORTH OF OUR CWA MONDAY AND
TUESDAY. THE SYSTEM WILL PROBABLY BE CLOSE ENOUGH TO SEND SOME EXTRA
CLOUDINESS AND PRECIPITATION TO NORTHERN PARTS OF THE FORECAST AREA.
POPS WERE LEFT IN THE SLGT CHC/LOW CHC RANGE ATTM. CONFIDENCE IS
LIMITED WITH THE SYSTEM WITH THE LATEST MODELS OFFERING SOMEWHAT
DIFFERENT SOLUTIONS. TEMPERATURES WILL LIKELY BE TOO WARM TO SUPPORT
ANY FROZEN PRECIPITATION WITH THE SYSTEM. A FEW FLAKES ACROSS THE
SOUTHERN POCONOS WOULD NOT BE TOO SURPRISING THOUGH. OVERALL, WE DID
NOT MAKE ANY SIGNIFICANT CHANGES, ALTHOUGH DID BLEND IN A SMALL
PERCENTAGE OF THE 00Z MOSGUIDE TO SOME FIELDS TO INTRODUCE SOME NEW
GUIDANCE INTO THE DATABASE.
