The episode as NWS PHI wrote it up.
Strong to high winds occurred across Delaware from around Midnight EST into the middle of the afternoon on the 31st. Peak wind gusts reached between 45 mph and 65 mph and downed weak trees, tree limbs and power lines and caused scattered outages. Delmarva Power reported about 5,400 of its customers lost power. All of the high winds and most of the highest wind gusts occurred in the south to southwest flow preceding a cold frontal passage during the early morning on the 31st. However, strong wind gusts near 50 mph continued in the westerly flow following the cold frontal passage during the morning and early afternoon on the 31st. The cold front moved through the state between 5 a.m.EST and 6 a.m. EST.
Peak wind gusts included 63 mph in Lewes (Sussex County), 61 mph in Dewey Beach (Sussex County), 56 mph in Dover (Kent County) and Georgetown (Sussex County) and 47 mph at the New Castle County Airport.
The strong to high winds were caused by a land bombing low pressure system that intensified rapidly as it moved through the Great Lakes on January 30th and into Quebec Province on January 31st. The central pressure of the low pressure system over Illinois deepened from 992 millibars at 7 a.m. EST on the 30th to 968 millibars at 7 a.m. EST on the 31st when it was in Quebec Province. The low pressure system continued to deepen and the following morning, the pressure was 944 millibars as it was crossing the Labrador Sea (The lowest analyzed pressure with this system was 940 millibars.). The rapid deepening of the surface low intensified the southerly flow preceding its cold front and then the pressure gradient (difference) between the low pressure system and a high pressure system entering the Northern Plains continued strong winds into the afternoon of the 31st. The low pressure system movement away from Delaware caused the strong winds to stop later that day.
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 Jan 30, 8:55 PM EST, 2 hours 5 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
855 PM EST WED JAN 30 2013
.SYNOPSIS...
A VERY STRONG COLD FRONT WILL PUSH THROUGH THE REGION OVERNIGHT.
A WEAK LOW PRESSURE SYSTEM WILL QUICKLY MOVE ACROSS THE MID
ATLANTIC FRIDAY MORNING, THEN HIGH PRESSURE BUILDS TO OUR SOUTH
FRIDAY NIGHT AND SATURDAY. THE NEXT COLD FRONT IS SCHEDULED TO
ARRIVE SUNDAY, THEN HIGH PRESSURE BRIEFLY ARRIVES SUNDAY NIGHT
INTO MONDAY, BEFORE ANOTHER COLD FRONT MOVES THROUGH TUESDAY.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
A STRONG COLD FRONT EXTENDED SOUTHWARD FROM LOW PRESSURE IN MICHIGAN
TO THE CENTRAL GULF COAST THIS AFTERNOON. THE BOUNDARY WILL RACE TO
THE EAST AND IT SHOULD PASS THROUGH OUR REGION BETWEEN ABOUT 200 AM
AND 600 AM. UNTIL THAT TIME WE ARE EXPECTING WINDY CONDITIONS AND
RAIN SHOWERS.
A BATCH OF SHOWERS EARLIER MADE ITS WAY ACROSS SE PA AND THE
DELMARVA...BUT STALLED BEFORE MOVING INTO WRN NJ. ANOTHER BATCH OF
SHOWERS IS NOW ORGANIZING ACORSS THE WRN PARTS OF THE CWA AND WILL
SWEEP NE ACROSS THE REGION OVERNIGHT. THESE SHOWERS WILL BE HEAVY
AT TIMES AND BE ACCOMPANIED BY VERY GUSTY WINDS AT TIMES. THE MODEL
CONSENSUS IS SETTLING ON ABOUT A HALF INCH TO AN INCH OF RAIN ON
THE COASTAL PLAIN. FROM THE FAR UPPER DELMARVA THROUGH OUR
COUNTIES IN EASTERN PENNSYLVANIA AND INTO NORTHWESTERN NEW JERSEY,
AMOUNTS OF ONE TO ONE AND A HALF INCHES SHOULD BE COMMON WITH
ISOLATED TOTALS AROUND 2 INCHES. AS A RESULT, THE FLOOD WATCH WILL
BE LEFT IN PLACE FOR TONIGHT. WITH THE STRONG LIFT, WE WILL ALSO
CONTINUE TO MENTION SCATTERED THUNDERSTORMS IN ADVANCE OF THE COLD
FRONT.
A VERY IMPRESSIVE SOUTH TO SOUTHWEST LOW LEVEL JET HAS DEVELOPED
AHEAD OF THE COLD FRONT. WIND SPEEDS AT 925 HPA WILL BE IN EXCESS
OF 80 KNOTS AROUND MIDNIGHT, MAINLY NEAR THE COAST. AS A RESULT,
THE HIGH WIND WARNING AND THE WIND ADVISORY WILL BE CONTINUED. DUE
TO THE SLIGHTLY SLOWLY TIMING OF THE FRONT, THE ENDING TIMES FOR
BOTH HAVE BEEN EXTENDED BY ABOUT AN HOUR. ANY MODERATE TO HEAVY
RAIN SHOWERS AND THUNDERSTORMS WILL EASILY MIX VERY STRONG WIND
GUSTS TO THE SURFACE.
AFTER THE COLD FRONT PASSES, THE WIND WILL SHIFT TO THE WEST
SOUTHWEST AND STRONG COLD ADVECTION WILL BEGIN. TEMPERATURES SHOULD
REMAIN VERY MILD AHEAD OF THE BOUNDARY AND THEY WILL FALL RAPIDLY
AFTER IT PASSES.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH 6 PM THURSDAY/...
THURSDAY WILL FEATURE STRONG COLD ADVECTION, ESPECIALLY IN THE
MORNING. TEMPERATURES WILL BE MUCH CLOSER TO SEASONABLE LEVELS THAN
THEY WERE TODAY. DUE TO THE COLD ADVECTION, WE ARE ANTICIPATING A
FAIR AMOUNT OF STRATOCUMULUS, ESPECIALLY OVER OUR NORTHERN AND
WESTERN COUNTIES.
THE WESTERLY WIND WILL BECOME QUITE STRONG FOR THURSDAY AND WIND
GUSTS MAY NEAR THE ADVISORY CRITERION. WE WILL WAIT UNTIL THE
CURRENT HIGH WIND WARNING AND WIND ADVISORY EXPIRE BEFORE ADDRESSING
THE POTENTIAL WIND ADVISORY FOR THURSDAY.
&&
.LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/...
COLD AIR ADVECTION WILL CONTINUE THROUGH SATURDAY MORNING AS THE
MID-LEVEL RIDGING SLIDES TO OUR EAST ALLOWING MEAN TROUGHING TO
SETUP ACROSS THE REGION. THE FIRST OF MANY MID-LEVEL SHORTWAVE
TROUGHS OF LOW PRESSURE WILL APPROACH FROM THE WEST EARLY FRIDAY
MORNING. THIS SYSTEM IS CONSIDERED TO BE A LOW AMPLITUDE PIECE OF
ENERGY AS IT MAKES NEARLY A B-LINE FROM THE OHIO VALLEY AND PASSES
JUST SOUTH OF OUR REGION. MODELS ARE SHOWING THERE IS A LITTLE BIT
OF QPF ASSOCIATED WITH THE EVENT...COUPLE HUNDREDTHS MAINLY ACROSS
OUR SOUTH AS THE SURFACE WAVE MOVES BY. GIVEN THE THERMAL PROFILES
WILL BE WELL BELOW FREEZING AND THERE IS A DECENT AMOUNT OF
MID-LEVEL LIFTING ASSOCIATED WITH THE VORT MAX, WE COULD SQUEEZE OUT
A FEW TENTHS OF AN INCH OF SNOW ACROSS A MAJORITY OF OUR AREA. THERE
IS STILL THE REALLY STRONG UPPER LEVEL JET JUST TO THE EAST OF THE
REGION WHICH COULD HELP TO INCREASE OMEGA PROVIDING A SLIGHTLY
BETTER CHANCE OF DENDRITIC SNOW GROWTH...THIS COULD INCREASE
SNOWFALL ACROSS THE SOUTHERN PORTIONS SPECIFICALLY.
HIGH PRESSURE THEN FOLLOWS FOR SATURDAY BEFORE THE NEXT SHORTWAVE
DIVES TO OUR SOUTH HELPING TO BRING A REINFORCING SHOT OF COLDER AIR
ON SUNDAY. BASED ON EXACTLY HOW FAR SOUTH THIS WAVE DIVES AND THE
POSITIONING OF THE JET DICTATE WHERE A SURFACE WAVE WILL FORM.
MODELS INDICATE MORE THAN LIKELY CYCLOGENESIS TAKES PLACE ALONG THE
NATURAL BAROCLINICITY OF THE COAST SUNDAY AFTERNOON. AS IT MOVES
FURTHER OFFSHORE IT DEEPENS AND COULD PROVIDE ANOTHER ROUND OF LIGHT
SNOW WITH MINIMAL ACCUMULATIONS.
AFTER SUNDAYS MID-LEVEL SYSTEM MOVES THROUGH THE FLOW LOOKS TO
BECOME MORE ZONAL AND MORE PROGRESSIVE THAN THE PRIOR FEW DAYS. WEAK
SURFACE RIDGING TO OUR SOUTH SHOULD KEEP THE MAJORITY OF MONDAY DRY
UNTIL THE THIRD EMBEDDED SHORTWAVE PUSHES EASTWARD. THIS SYSTEM
TAKES MORE TIME TO DEVELOP AS IT ENTERS THE GREAT LAKES REGION ON
TUESDAY. THE LOW-LEVEL FLOW TURNS MORE SOUTHERLY AS IT APPROACHES
AND WAA INDUCED PRECIPITATION IS POSSIBLE PROVING A MIXTURE OF
RAIN/SNOW ACROSS OUR REGION...AGAIN NOT MUCH QPF ASSOCIATED WITH IT.
THE ASSOCIATED COLD FRONT THEN SWINGS THROUGH LATER ON TUESDAY WITH
ANOTHER SHOT OF COLDER AIR AND RAIN/SNOW SHOWERS POSSIBLE. WITH A
MORE NORTH TRAJECTORY OF THE SURFACE WINDS ON WEDNESDAY CAN NOT
RULE OUT A FEW OROGRAPHICALLY INDUCED SNOW SHOWERS AND LAKE
STREAMERS THAT COULD MAKE IT INTO OUR AREA.
&&
.AVIATION /02Z THURSDAY THROUGH MONDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.
A VERY STRONG COLD FRONT FROM THE WEST SHOULD PASS ACROSS OUR TAF
SITES BETWEEN ABOUT 0800Z AND 1000Z. UNTIL THAT TIME, CONDITIONS
WILL VARY BETWEEN VFR AND MVFR WITH SOME IFR CONDITIONS LIKELY IN
THE HEAVIEST OF THE RAIN SHOWERS. SCATTERED THUNDERSTORMS ARE ALSO
POSSIBLE AFTER DARK. HOWEVER, THEIR TIMING AND COVERAGE REMAINS VERY
UNCERTAIN SO THEY HAVE NOT BEEN INCLUDED IN THE TAFS AT THIS POINT.
A GUSTY SOUTH WIND WILL CONTINUE UNTIL THE FRONT PASSES. ALSO, LOW
LEVEL WIND SHEAR WILL BE AN ISSUE. A VERY STRONG SOUTH SOUTHWEST
JET, WITH WIND SPEEDS IN EXCESS OF 70 KNOTS WITHIN A COUPLE THOUSAND
FEET OF THE GROUND, IS FORECAST FOR THIS EVENING AND FOR THE HOURS
AROUND MIDNIGHT.
AFTER THE COLD FRONT PASSES, CONDITIONS SHOULD IMPROVE TO VFR. A
GUSTY WEST WIND IS ANTICIPATED FOR THURSDAY. SUSTAINED SPEEDS MAY
BE IN THE 20 KNOT RANGE FOR MUCH OF THE DAY WITH GUSTS INTO THE 30S.
OUTLOOK...
THURSDAY NIGHT...STRONG WEST-NORTHWEST WINDS WITH GUSTS UPWARDS OF
40KTS STILL POSSIBLE...VFR.
FRIDAY...VFR WITH CONTINUED WEST WINDS AND STRONGER GUSTS. A FEW
SNOW SHOWERS ARE POSSIBLE WHICH COULD LOWER VSBYS...ESPECIALLY WITH
THE STRONGER WINDS.
SATURDAY...VFR WITH NW WINDS.
SUNDAY...MVFR OR LOWER IN SNOW SHOWERS.
MONDAY...VFR.
&&
.MARINE...
THE GALE WARNING WILL REMAIN IN EFFECT FOR TONIGHT AND THURSDAY.
FOR TONIGHT, A STRONG SOUTHERLY FLOW WILL CONTINUE UNTIL THE ARRIVAL
OF A COLD FRONT FROM THE WEST TOWARD DAYBREAK. A VERY STRONG SOUTH
SOUTHWESTERLY LOW LEVEL JET WILL BRING WIND SPEEDS IN EXCESS OF 70
KNOTS VERY CLOSE TO THE WATERS SURFACE. HOWEVER, WATER TEMPERATURES
ARE IN THE 40S AND THE AIR ADVECTING UP FROM THE SOUTH SHOULD BE IN
THE 60S. THAT CONTRAST WILL NOT ALLOW FOR EFFICIENT MIXING. WHILE
SOME GUSTS AROUND 50 KNOTS MAY REACH THE WATER'S SURFACE, MOST GUSTS
ARE EXPECTED TO BE IN THE GALE FORCE RANGE.
FOR THURSDAY, A STRONG WESTERLY FLOW IS ANTICIPATED TO DEVELOP IN
THE WAKE OF THE COLD FRONT. WIND GUSTS AGAIN MAY BE IN THE GALE
FORCE RANGE IN THE STRONG COLD AIR ADVECTION.
OUTLOOK...
A CONTINUED LOW-END OR HIGH END SMALL CRAFT LOOKS LIKELY THURSDAY
NIGHT INTO AT LEAST FRIDAY NIGHT AS A CONTINUED SURGE OF COLD AIR
MOVES ACROSS THE WATERS. HIGH PRESSURE WILL MOVE ACROSS ON SATURDAY
ALLOWING THE PRESSURE GRADIENT TO SLACKEN A BIT AND THE WINDS TO
DECREASE. A WAVE OF LOW PRESSURE LOOKS TO AFFECT OUR WATERS ON
SUNDAY AND COULD PROVIDE ANOTHER ROUND OF SMALL CRAFT/GALE FORCE
GUSTS THROUGH MONDAY.
&&
.TIDES/COASTAL FLOODING...
WE HAVE DECIDED TO ISSUE A COASTAL FLOODING ADVISORY FOR THE EASTERN
SHORE OF MARYLAND COUNTIES NEAR THE CHESAPEAKE BAY. THE STRONG SOUTH
WIND IS ALREADY IN PLACE AND THE TIDAL DEPARTURES HAVE RESPONDED
ACCORDINGLY. THESE DEPARTURES WILL CONTINUE TO RISE OVERNIGHT AND
MAY NOT DROP THAT QUICKLY...EVEN AFTER FRONTAL PASSAGE EARLY
THURSDAY MORNING. THE SURGE UP THE BAY EARLY THURSDAY EARLY MORNING
MAY BE DIRECTED AT THE WRN SHORE INITIALLY...BUT THEN WHEN THE WINDS
SHIFT...MAY BECOME MORE DIRECTED AT THE ERN SHORE.
THE HIGH TIDE TONIGHT WAS BELOW MINOR TIDAL FLOODING LEVELS. THE
HIGH TIDE THURSDAY MORNING WITH PROBABLY HAVE A BETTER CHC AT
REACHING MINOR TIDAL FLOODING LEVELS.
WE HAVE LOOKED AT THE FCST DEPARTURES ALONG THE COASTAL ATLANTIC AND
THE DELAWARE BAY/RIVER. AT THIS TIME IS DOES NOT APPEAR THAT ANY
MINOR TIDAL FLOODING LEVELS WILL BE REACHED IN THESE AREAS...BUT WE
WILL CONTINUE TO MONITOR...SINCE SOMETIMES THE LEVELS SHOOT UP
QUICKLY IN A STRONG SOUTH WIND.
OUTLOOK...
AFTER THE THREAT OF MINOR TIDAL FLOODING AS PASSED THERE COULD BE
SOME ISSUES WITH BLOW-OUT TIDES ON FRIDAY. STRONG WEST-NORTHWEST
WINDS COULD PUSH WATER LEVELS TO AROUND -1.5 TO -2.0 IN SOME
SPOTS. THE STRONG SOUTHERLY FLOW CURRENTLY TAKING PLACE ACROSS OUR
WATERS IS ALLOWING FOR A MASS TRANSPORT OF THE SURFACE WATER 90
DEGREES TO THE RIGHT...OUT TO SEA...AT LEAST IN THEORY.
GUIDANCE HAS BEEN SHOWING THE POTENTIAL FOR BLOW-OUTS FOR A FEW
DAYS NOW BUT IT IS NOT A DEFINITE SCENARIO. THE ADDED FRESH WATER
FROM THE OVERNIGHT RAINS ON WEDNESDAY AND THURSDAY COULD HELP TO
INHIBIT BLOW-OUT FROM OCCURING.
