As the offshore low pressure system continued to intensify, the approximately eighty millibar surface pressure difference between it and a strong high pressure system in the middle of the United States produced strong winds in Sussex County Delaware during the first part of the day on the 12th. Peak wind gusts in Sussex County averaged around 50 mph and knocked down weak tree limbs and wires.

The episode as NWS PHI wrote it up.
As the offshore low pressure system continued to intensify, the approximately eighty millibar surface pressure difference between it and a strong high pressure system in the middle of the United States produced strong winds in Sussex County Delaware during the first part of the day on the 12th. Peak wind gusts in Sussex County averaged around 50 mph and knocked down weak tree limbs and wires. They included 52 mph in Lewes and 48 mph in Dewey Beach. Peak wind gusts elsewhere in Delaware were closer to 40 mph. The strongest wind gusts ceased around sunrise on the 12th as the low pressure system started to weaken as it was moving through the Canadian Maritimes.

NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Feb 11, 9:52 PM EST, 3 hours 8 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 952 PM EST SAT FEB 11 2012 .SYNOPSIS... LOW PRESSURE EXITING TO THE CANADIAN MARITIMES AND HIGH PRESSURE TO OUR WEST OVER THE PLAINS STATES WILL PRODUCE A STRONG NORTHWESTERLY FLOW WITH COLDER AIR MOVING INTO OUR REGION. A FRONTAL BOUNDARY, CURRENTLY OVER EASTERN PORTIONS OF THE FORECAST AREA, WILL EXIT TO THE EAST TONIGHT. HIGH PRESSURE WILL BUILD INTO THE MID ATLANTIC REGION MONDAY, FOLLOWED BY A COUPLE OF WEAK SYSTEMS AFFECTING THE AREA DURING THE MIDDLE TO END OF THE UPCOMING WEEK. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... TWO FORECAST ISSUES FOR TONIGHT INCLUDE SNOW SHOWERS/SQUALLS WITH THE ARCTIC FRONT...AND WIND GUSTS IN THE COLD AIR ADVECTION BEHIND THE FRONT. A WIND ADVISORY HAS BEEN ISSUED FOR SOUTHERN PORTIONS OF THE AREA. CURRENTLY...THE ARCTIC FRONT, AND ASSOCIATED SNOW SHOWERS/SQUALLS, IS OVER NEW JERSEY. THE FRONT WILL EXIT TO THE EAST BY AROUND MIDNIGHT BRINGING AN END TO THE HEAVIER SNOW SHOWERS/SQUALLS. A FEW LIGHTER SNOW SHOWERS OR FLURRIES COULD LINGER INTO THE EARLY MORNING HOURS. SNOW ACCUMULATIONS WITH THE HEAVIER SHOWERS/SQUALLS HAVE GENERALLY BEEN IN THE 1/2 TO 1 1/2 INCH RANGE AND MOSTLY ON NON ROADWAY SURFACES. ALTHOUGH, WITH THE COLDER AIR PUSHING IN, SOME SECONDARY AND NON-TREATED ROADWAYS HAVE BECOME OR ARE BECOMING SNOW COVERED. THE ACCUMULATING SNOW WILL END AS THE HEAVIER SNOW SHOWERS MOVE OFF TO THE EAST DURING THE NEXT 3 OR 4 HOURS. BEHIND THE ARCTIC FRONT, WE ARE LOOKING AT IMPRESSIVE COLD AIR ADVECTION AND A TIGHTENING GRADIENT THAT WILL BRING STRONG WINDS OVERNIGHT, MAINLY ACROSS SOUTHERN AREAS. THE PRESSURE GRADIENT LOOKS TO FALL OUT ACROSS THE SOUTHERN HALF OF THE FORECAST AREA...WITH THE TIGHTEST GRADIENT BETWEEN 0600 AND 1200 UTC SUNDAY. DURING THE BEST COLD AIR ADVECTION...MODEL SOUNDINGS FROM BOTH THE 1200 UTC NAM AND GFS SHOW 45 KNOT WINDS AT THE TOP OF THE INVERSION NEAR 2100 FEET...PEAKING BETWEEN 0600 UTC AND 0900 UTC. THIS IS PROBABLY BORDERLINE FOR WIND ADVISORY CRITERIA...BUT 3 HOUR PRESSURE RISES NEAR 5 MB MAY BE ENOUGH TO ALLOW SOME OF THAT MOMENTUM TO REACH THE SURFACE. THE WIND ADVISORY COVERS NORTHEAST MARYLAND...DELAWARE...A PART OF SOUTHEAST PENNSYLVANIA (INCLUDING PHILADELPHIA)...AND THE SOUTHERN HALF OF NEW JERSEY. WHILE THE STRONGEST WINDS MAY BE JUST SOUTH OF AN KMQS-KPHL-KMJX...THE NORTHERN EDGE OF THE WIND ADVISORY WILL INCLUDE THE METRO AREA. LOWS TONIGHT SHOULD OCCUR TOWARD DAYBREAK IN THE BEST COLD AIR ADVECTION. GIVEN WHAT IS OCCURRING TO THE WEST NOW...LOWS WERE BASED ON THE COLDER GFS MOS NUMBERS. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY/... COLD AIR ADVECTION WILL BE IN PROGRESS SUNDAY MORNING...AS THE STRONGEST LOW TO MID LEVEL WINDS MOVE JUST OFFSHORE. THE PRESSURE GRADIENT IS AT ITS TIGHTEST IN THE MORNING...AND AT THIS POINT DOES NOT APPEAR TO SUPPORT WIND ADVISORY LEVELS GUSTS. MODEL SOUNDINGS ALSO SUGGEST THAT THE GUST POTENTIAL REMAINS BELOW WIND ADVISORY LEVELS AS WELL. A SECONDARY COLD FRONT WILL CROSS THE REGION IN THE AFTERNOON... SUPPORTED BY A FAIRLY VIGOROUS MID LEVEL SHORT WAVE. THE COLD AIR ADVECTION BEHIND THESE FEATURES COULD RESULT IN WIND GUSTS GETTING CLOSE TO WIND ADVISORY LEVELS DURING THE MID TO LATE AFTERNOON (WHICH IS SUPPORTED BY MODEL SOUNDINGS AROUND 2100 UTC). WHILE THERE IS SOME POTENTIAL FOR GUSTS TO REACH 45 MPH SUNDAY AFTERNOON...WILL HOLD OFF ON DOING THAT JUST YET. SOME CLEARING IS POSSIBLE IN THE MORNING AS THE COLD AIR ADVECTION MAXIMIZES AND DRY AIR SETTLES IN BEHIND THE ARCTIC FRONT. THIS MAY END UP BEING SHORT LIVED HOWEVER...AS THE CONVECTIVE TEMPERATURES PLUMMET IN THE NEW AIRMASS. MODEL SOUNDINGS SUGGEST THAT CUMULUS WILL DEVELOP DURING THE MID MORNING HOURS...AND WILL SPREAD OUT UNDER THE INVERSION DURING THE AFTERNOON. IN ADDITION...MID LEVEL CLOUDINESS WITH THE ABOVEMENTIONED SHORT WAVE PROBABLY COVERS MOST OF THE NORTHERN TWO THIRDS OF THE AREA IN THE AFTERNOON. SO...MOST PLACES SHOULD SEE SOME SUNSHINE FADE BEHIND CLOUDINESS (WHILE THE TERRAIN MAY SEE LITTLE IF ANY SUN DURING THE DAY SUNDAY. THE SHORT WAVE WILL ALSO INCREASE THE UPSLOPE FLOW ACROSS THE HIGHER TERRAIN...AND THIS COULD RESULT IN SCATTERED SNOW SHOWERS IN THE MOUNTAINS DURING THE MORNING. THE REINFORCING COLD FRONT IN THE AFTERNOON MAY ENHANCE THIS...BUT FOR NOW THE SNOW SHOWER CHANCES WERE CAPPED. IN ADDITION...FLURRIES WITH THE SHORT WAVE WERE CARRIED ACROSS THE UPPER DELAWARE VALLEY...AS WELL AS MUCH OF NORTHERN NEW JERSEY. 850 MB TEMPERATURES STABILIZING NEAR MINUS 14 CELSIUS SUGGEST THAT HIGHS IN MOST PLACES OUTSIDE THE TERRAIN SHOULD TOP OUT NEAR THE FREEZING MARK. THIS IS CLOSER TO THE COLDER NAM MOS NUMBERS...WHICH WERE USED FOR HIGHS. && .LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/... TO BEGIN THE LONG TERM, A STRONG MID LEVEL TROUGH AND A WEAK FRONT WILL BE EXITING OFF TO OUR EAST. OTHER THAN SOME LEFTOVER FLURRIES IN THE NORTHWEST FLOW OVER THE HIGHER TERRAIN OF THE POCONOS, A DRY FORECAST HAS BEEN MAINTAINED FOR SUNDAY NIGHT AS THE ABOVE FEATURES MOVE EAST AND HIGH PRESSURE TO OUR SOUTHWEST GRADUALLY BEGINS TO BUILD INTO THE REGION. HIGH PRESSURE NEARBY WILL YIELD FAIR WEATHER ACROSS THE REGION ON MONDAY WITH AMPLE SUN AND TEMPERATURES A FEW DEGREES MILDER THAN OVER THE WEEKEND. FOR THE TUESDAY TO WEDNESDAY TIMEFRAME, THE ECMWF AND GFS CONTINUE TO SHOW A FAIRLY DISORGANIZED MID LEVEL DISTURBANCE PASSING THROUGH THE MID ATLANTIC REGION. WITH DIFFERENCES BETWEEN THE MODELS ON THE HANDLING OF THIS SYSTEM, FEW CHANGES WERE MADE IN THIS TIMEFRAME WITH SLIGHT CHANCE POPS FOR RAIN/SNOW SHOWERS MAINTAINED. OF NOTE WILL BE THE MODERATING TREND IN TEMPERATURES AS MORE OF A SOUTHWESTERLY FLOW WILL BE IN PLACE DURING THIS TIMEFRAME. FOR THE END OF THE WEEK, A STRONGER SYSTEM MAY POTENTIALLY AFFECT THE REGION. FOR NOW, THE MODELS HAVE LOW PRESSURE APPROACHING FROM THE OHIO VALLEY REGION ON THURSDAY, WITH THIS SYSTEM REACHING OUR AREA THURSDAY NIGHT INTO FRIDAY. HOWEVER, THERE IS QUITE A BIT OF DIFFERENCE BETWEEN THE MODELS WITH THE TRACK AND STRENGTH OF LOW PRESSURE. FOR NOW, CHANCE AND SLIGHT CHANCE POPS WERE KEPT FROM THURSDAY NIGHT INTO FRIDAY WITH THE PASSAGE OF THIS SYSTEM. WHAT DOES LOOK TO CONTINUE THROUGH THE END OF THE WEEK ARE THE MODERATING TEMPERATURES, WITH HIGH TEMPERATURES RANGING FROM THE MID 40S NORTH TO THE LOW 50S SOUTH ON FRIDAY. FOR THE MOST PART, A BLEND OF MOS AND HPC GUIDANCE ALONG WITH CONTINUITY WAS USED FOR TEMPERATURES THROUGH THE LONG TERM PERIOD. && .AVIATION /03Z SUNDAY THROUGH THURSDAY/... THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY AND SURROUNDING AREAS. VARYING CONDITIONS, RANGING FROM IFR TO VFR THIS EVENING, WILL IMPROVE AS THE SHOW SHOWERS END FROM WEST TO EAST AND THE ARCTIC FRONT MOVES OFF THE COAST. EXPECT VFR CONDITIONS TO RETURN AFTER 0600 UTC SUNDAY. HOWEVER...THE GRADIENT BEHIND THE ARCTIC FRONT TIGHTENS FAIRLY QUICKLY...AND SHOULD EASILY SUPPORT SUSTAINED WINDS BETWEEN 17 AND 22 KNOTS ACROSS THE BOARD. MODEL SOUNDINGS SUGGEST THAT WINDS WILL RANGE BETWEEN 35 AND 41 KNOTS AT THE TOP OF THE INVERSION DURING THE BEST OF THE COLD AIR ADVECTION...SO GUSTS TO 35 KNOTS ARE EXPECTED DURING THE OVERNIGHT HOURS...WITH THE STRONGEST GUSTS FROM KPHL SOUTH. VFR CEILINGS COULD BREAK FOR A TIME LATER TONIGHT AND SUNDAY MORNING. THE NEW AIRMASS HAS FAIRLY LOW CONVECTIVE TEMPERATURES ASSOCIATED WITH IT...SO SUNSHINE WILL BE SELF DESTRUCTIVE...ALLOWING CUMULUS/STRATOCUMULUS TO DEVELOP. THE GRADIENT CONTINUES TO SUPPORT SUSTAINED WINDS BETWEEN 18 AND 25 KNOTS FOR THE REMAINDER OF THE DAY...AFTER A BRIEF LULL NEAR SUNRISE. MODEL SOUNDINGS SUGGEST THAT THE GUST POTENTIAL IS NOT QUITE AS HIGH AS TONIGHT...AS THE MOMENTUM TRANSFER IS NOT AS EFFICIENT AS TONIGHT. OUTLOOK... WITH HIGH PRESSURE GRADUALLY BUILDING INTO THE REGION FROM SUNDAY NIGHT THROUGH MONDAY, VFR CONDITIONS ARE EXPECTED. IN THE LATE TUESDAY TO WEDNESDAY TIMEFRAME, A WEAK SYSTEM MAY BRING PRECIPITATION AND SOME LOWERING IN CEILINGS OR VISIBILITIES TO THE AREA. && .MARINE... THE GRADIENT IS STARTING TO INCREASE AS THE SURFACE LOW DEEPENS WELL TO THE EAST OF THE NORTH CAROLINA COAST. WINDS AND SEAS ARE ON THE THRESHOLD OF SMALL CRAFT LIMITS...ESPECIALLY ACROSS THE SOUTHERN WATERS. AN ARCTIC COLD FRONT WILL CROSS THE WATERS BY AROUND MIDNIGHT. THE GRADIENT BEHIND THE FRONT IN THE COLD AIR ADVECTION IS IMPRESSIVE OVER LAND TO THE WEST...WHERE GUSTS TO 35 KNOTS HAVE BEEN COMMON. THE GALE FORCE GUSTS ARE EXPECTED TO COMMENCE SHORTLY AFTER THE PASSAGE OF THE ARCTIC FRONT. THE PRESSURE GRADIENT REACHES IT MAXIMUM BETWEEN 0600 UTC AND 1200 UTC SUNDAY. DURING THIS TIME...THE GRADIENT LOOKS TO SUPPORT GALE FORCE WINDS ACROSS ALL WATERS...WITH THE HIGHEST GUST POTENTIAL ACROSS THE SOUTHERN OCEAN WATERS AND LOWER DELAWARE BAY. THE GRADIENT MAINTAINS AN INTENSITY SLIGHTLY LOWER THAN LATE TONIGHT FOR MOST OF SUNDAY. THE HIGHEST WINDS GUSTS PROBABLY OCCUR IN THE MORNING ACROSS THE SOUTHERN WATERS. IN FACT...WINDS COULD DROP BELOW GALE FORCE FOR A TIME LATE IN THE MORNING AND EARLY AFTERNOON. ANOTHER COLD FRONT DROPPING ACROSS THE WATERS IN THE AFTERNOON COULD BRING WINDS BACK TO GALE FORCE...AS ANOTHER SHORT OF COLD AIR CROSSES THE WATERS. MODEL SOUNDINGS SUGGEST THAT GUSTS BETWEEN 35 AND 40 KNOTS ARE POSSIBLE ACROSS THE NORTHERN OCEAN WATERS...WITH SLIGHTLY LESS POTENTIAL ACROSS THE SOUTHERN WATERS. GALE CONDITIONS ARE ANTICIPATED TO LINGER INTO SUNDAY NIGHT, WITH DECREASING WINDS AND DIMINISHING SEAS GOING INTO EARLY MONDAY. IN FACT, FROM MONDAY THROUGH MID-WEEK, WINDS AND SEAS ARE EXPECTED TO BE BELOW ADVISORY CRITERIA, WITH HIGH PRESSURE OVER THE REGION ON MONDAY AND A WEAK SYSTEM MOVING THROUGH THE AREA FOR MID-WEEK. && .TIDES/COASTAL FLOODING... AS THE STRONG NORTHWEST FLOW DEVELOPS...ANY POSITIVE TIDE DEPARTURES ON THE OCEAN AND ACROSS THE BAYS SHOULD DISAPPEAR. NONE OF THE TIDAL GUIDANCE SUGGESTS THAT BLOWOUT TIDES WILL BE AN ISSUE TONIGHT AND SUNDAY. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...WIND ADVISORY UNTIL 5 AM EST SUNDAY FOR PAZ067-070-071.
