The episode as NWS PHI wrote it up.
The combination of an unseasonably hot and humid air mass, an approaching cold front and strong winds aloft caused a squall line of strong to severe thunderstorms to move through Delaware during the late afternoon and early evening of the 23rd. Hardest hit was the northern part of the state. A wind gust of 66 mph was recorded at the New Castle County Airport. Delmarva Power and Light reported 63,000 of its customers lost power on the Delmarva Peninsula (14,000 in New Castle County) and it took until the 26th to fully restore power in Delaware. Verizon phone service was also interrupted.
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 Jun 23, 3:20 PM EST, 1 hour 15 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
420 PM EDT TUE JUN 23 2015
.SYNOPSIS...
A COLD FRONT WILL MOVE ACROSS THE AREA THIS EVENING, PUSHING SOUTH
OF THE AREA AND STALLING NEAR THE CAROLINAS WEDNESDAY. HIGH
PRESSURE BRIEFLY BUILDS ACROSS THE AREA WEDNESDAY INTO WEDNESDAY
NIGHT. SEVERAL WAVES OF LOW PRESSURE ARE FORECAST TO DEVELOP ALONG
THE FRONTAL BOUNDARY, AND COULD AFFECT OUR AREA FOR THE END OF THE
WEEK INTO THE WEEKEND. WEAK HIGH PRESSURE MAY BRIEFLY AFFECT THE
AREA EARLY NEXT WEEK, BEFORE ANOTHER FRONT APPROACHES THE AREA.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
A SEVERE THUNDERSTORM WATCH IS IN EFFECT FOR THE ENTIRE FORECAST
AREA THROUGH 1100 PM.
THE ATMOSPHERE REMAINS RIPE WITH SBCAPES NOW EXCEEDING 3K J/KG.
FINALLY SOME CU POPPING UP ACROSS THE REGION WITH THE CAP BREAKING
DOWN.
HEAT INDICES ARE IMPRESSIVE...AROUND 100 ACROSS THE I95 CORRIDOR. UP
TO 103 ACROSS THE DELMARVA. THE HEAT ADVISORY WILL RUN UNTIL 6 PM.
THE COLD FRONT WILL MOVE OFF THE COAST OVERNIGHT. SURFACE HIGH
PRESSURE, CENTERED ACROSS THE UPPER MISSISSIPPI VALLEY THIS
AFTERNOON, WILL MOVE EAST BEHIND THE DEPARTING COLD FRONT.
DEWPOINTS BEHIND THE FRONT WILL DROP ABOUT 10 DEGREES BY MORNING.
LOWS WILL FALL INTO THE UPPER 50S NORTH AND WEST, TO AROUND 70
ACROSS THE I95 CORRIDOR, AND INTO THE LOWER 70S ACROSS THE
SOUTHEASTERN ZONES.
SKIES WILL CLEAR OVERNIGHT. LOTS OF SUNSHINE EXPECTED BY TOMORROW'S
SUNRISE.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH 6 PM WEDNESDAY/...
WEAK SURFACE HIGH PRESSURE WILL TRACK ACROSS THE ENTIRE REGION
ON WEDNESDAY WITH JUST ENOUGH STRENGTH TO HELP KEEP THE SKIES BLUE.
DOESN'T LOOK LIKE CONVECTIVE TEMPS ARE GOING TO BE REACHED TOMORROW,
UNTIL VERY LATE IN THE DAY, IF AT ALL. SO LOTS OF SUN, COMFORTABLE
DEWPOINTS AND TEMPERATURES CAN BE EXPECTED. SHAPING UP TO BE A
REALLY NICE DAY.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
WEAK HIGH PRESSURE BEGINS TO LOSE ITS GRIP ON THE AREA WEDNESDAY
NIGHT INTO THURSDAY MORNING WITH GENERALLY DRY WEATHER EXPECTED
WEDNESDAY NIGHT INTO THURSDAY MORNING. MEANWHILE, AN AREA OF LOW
PRESSURE IS FORECAST TO BE MOVING THROUGH THE OHIO RIVER VALLEY,
WHICH WILL LIKELY BEGIN TO LIFT THE FRONT LOCATED TO OUR SOUTH
BACK NORTHWARD TOWARD THE AREA. THE FRONT MAY NOT FULLY MAKE IT
BACK INTO OUR AREA, HOWEVER, ADDITIONAL WAVES OF LOW PRESSURE ARE
EXPECTED TO DEVELOP ALONG THE FRONT AND SKIRT JUST TO OUR SOUTH
DURING THE WEEKEND. AGAIN, WHILE THE LOW PRESSURE SYSTEMS MAY NOT
FULLY CROSS OVER THE AREA, THEY WILL LIKELY BE CLOSE ENOUGH TO
BRING OUR AREA A FEW PERIODS OF RAINFALL THROUGH THE WEEKEND.
THURSDAY INTO THURSDAY NIGHT LOOKS TO BE THE ONLY TIME PERIOD WHEN
THERE IS ANY INSTABILITY FORECAST, SO WE WILL ONLY CARRY A CHANCE
OF THUNDERSTORMS THURSDAY INTO THURSDAY NIGHT, WITH JUST PLAIN
SHOWERS THE REST OF THE PERIOD.
AFTER THE LAST OF THE LOW PRESSURE SYSTEMS PASSES EAST AND PULLS
AWAY FROM THE AREA SUNDAY NIGHT, HIGH PRESSURE IS FORECAST TO
BRIEFLY BUILD ACROSS THE AREA MONDAY INTO MONDAY NIGHT. THIS SHOULD
PROVIDE A BRIEF DRY PERIOD MONDAY INTO MONDAY NIGHT. A FEW SCATTERED
SHOWERS ARE POSSIBLE MONDAY AFTERNOON, BUT OVERALL DRY WEATHER IS
EXPECTED.
ON TUESDAY INTO TUESDAY NIGHT, A COLD FRONT IS EXPECTED TO APPROACH
AND MOVE ACROSS THE AREA. THIS WILL BRING ANOTHER CHANCE OF
SHOWERS AND THUNDERSTORMS TO THE AREA.
TEMPERATURES COOL DOWN FOR THE END OF THE WEEK, AND ESPECIALLY INTO
THE WEEKEND AS THERE WILL LIKELY BE QUITE A BIT OF CLOUD COVER, AND
AN EAST/NORTHEAST FLOW SHOULD HELP KEEP THE AREA COOLER THAN
NORMAL. TEMPERATURES ARE EXPECTED TO BEGIN TO WARM EARLY NEXT
WEEK, BUT MAY NOT RETURN TO NORMAL UNTIL TUESDAY.
&&
.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
