The episode as NWS PHI wrote it up.
Scattered strong to severe thunderstorms developed ahead of an approaching cold front, producing pockets of very heavy rain and some wind damage across northern parts of the Eastern Shore during the early evening of the 22nd. Delmarva Power and Light reported about 20,000 of its customers lost power in New Castle and Cecil Counties. Power was not fully restored until the night of the 24th.
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 22, 4:58 PM EST, 41 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 558 PM EDT FRI JUN 22 2012 .SYNOPSIS... A COLD FRONT WILL SWEEP THROUGH THE REGION EARLY THIS EVENING FOLLOWED BY WEAK HIGH PRESSURE ON SATURDAY AND SUNDAY. ANOTHER COLD FRONT WILL APPROACH THE REGION LATE SUNDAY NIGHT INTO MONDAY MORNING. THE FRONT WILL MOVE THROUGH ON MONDAY AND THEN HIGH PRESSURE WILL AFFECT OUR WEATHER THROUGH THE UPCOMING WEEK. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... THE SEVERE THUNDERSTORM WATCH WAS CANCELLED FOR THE 6 NORTHWEST COUNTIES...CARBON, MONROE, BERK, LEHIGH, NORTHAMPTON IN PENNSYLVANIA AND SUSSEX AND WARREN IN NEW JERSEY. THE WATCH REMAINS FOR THE REMAINDER OF THE AREA. ACTIVE SEVERE WEATHER OPERATIONS ONGOING. HEAT RELATED ADVISORIES AND WARNINGS ARE ALLOWED TO EXPIRE. RERGED POSTED. PHL REACHED 94F. MOST OF THE STORMS IN OUR AREA THROUGH 330 PM WERE SEABREEZE INITIATED AND THEN REFIRED A BIT ON SOME OF THE OUTFLOWS. WATCHES CONTINUE BUT THERE IS SOME DOUBT ABOUT HOW MUCH WILL OCCUR IN E PA FROM KRDG TO KABE TO KFWN NORTHWESTWARD. BLV MOST OF THE FOCUS WILL SHIFT TO DE/MD BY THIS EVENING WHERE EXCESSIVE RAIN IS POSSIBLE. NO WATCH DUE TO UNCERTAINTY BUT WONT BE SURPRISED AT 4 INCHER SOMEWHERE DOWN THERE. SAME PHILOSOPHY AS EARLIER... HIGH PWAT OF 1.9 INCHES ALONG AND E OF THE I95 CORRIDOR...TT GROWING TO 48-51 WITH MARGINAL SHEAR SHOULD LEAD TO SLOW EWD MOVING BUT SEWD DEVELOPING STRONG TSTMS THIS AFTN. USING 00Z-12Z/22 NMM/ARW COMPARISON WITH 00Z-12Z/22 SPC WRF TO GUIDE THE FCST. EXPECTING HEAVIEST TSTMS FROM NE MD THRU S NJ WHERE BETTER INSTABILITY...CLOSER TO DIFFLUENT THICKNESS. STORM OUTFLOW GUSTS SHOULD BE NW 30-45 KTS EXCEPT IF ANY SVR STORMS. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/... THE CONVECTIVE POTENTIAL WILL CONTINUE THROUGH ABOUT 0300 UTC...AS THE MARGINAL SHEAR MAXES OUT IN PROXIMITY TO THE CONVECTION. THE SLOWLY MOVING COLD FRONT WILL ACT AS A FOCUS FOR CONVECTION MOST OF THE NIGHT...BUT THE STRONG WIND GUSTS SHOULD BE LIMITED TO THE EVENING HOURS. WITH THE TRUE AIRMASS CHANGE STILL RUNNING BEHIND THE FRONT...LOWS WERE BASED ON A COMBINATION OF THE WARMER GFS MOS NUMBERS AND THE PREVIOUS FORECAST. HEAVIEST CONVECTION SLOWLY WANES DURING THE NIGHT. BLENDED NCEP MOS GUIDANCE BUT APPEARS TO BE FOCUSED IN DE/MD SOUTHWARD. SATURDAY...ANY LINGERING SHOWERS ALONG THE COASTS END QUICKLY BUT HIGH CLOUDINESS MAY LINGER A BIT THRU FORENOON. NCEP BLENDED GUIDANCE FOR A MUCH MORE COMFORTABLE DAY. POSSIBILITY THAT THE HEAT WAVE MAY CONTINUE FROM THE VICINITY OF PHL SOUTHWARD TOMORROW BUT WITH MUCH LOWER DEWPOINTS. && .LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/... HIGH PRESSURE AT THE SURFACE SHOULD BE OVERHEAD SATURDAY NIGHT AND SUNDAY MORNING. WE SHOULD DECOUPLE NICELY AND TEMPERATURES AND DEWPOINTS WILL BE A LITTLE BELOW SEASONAL NORMS (AND MUCH LESS THAN WHAT WE SAW DURING THE RECENT HEAT WAVE). HIGH PRESSURE SLIDES TO THE EAST ON SUNDAY AND A COLD FRONT BRINGING A REINFORCING PUSH OF COOLER AIR WILL SWEEP THROUGH THE REGION SUNDAY NIGHT INTO MONDAY MORNING. THE FRONT IS EXPECTED TO TOUCH OFF ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS BEFORE MOVING OFFSHORE LATER IN THE DAY. MODELS HAVE BEEN CONSISTENTLY SHOWING A PATTERN CHANGE BACK TO EAST COAST TROUGHING. UPPER LEVEL LOW PRESSURE OVER HUDSON BAY WILL KEEP US IN A CYCLONIC FLOW. AS THE LOW BEGINS TO SAG TOWARDS THE SOUTH AND EAST MULTIPLE VORT MAXES PASS THROUGH EACH DAY FROM TUESDAY THROUGH THURSDAY KEEPING US IN A FAIRLY UNSETTLED PATTERN WITH COOLER THAN NORMAL TEMPERATURES. TEMPERATURES BEGIN TO WARM TOWARD MORE NORMAL VALUES ON FRIDAY. && .AVIATION /22Z FRIDAY THROUGH WEDNESDAY/... THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY AND SURROUNDING AREAS. REMAINDER THIS AFTERNOON...VFR SCT-BKN CLOUD AOA 7000 FT. IFR IN CLUSTERS OF SHOWERS AND TSTMS WITH SOME OUTFLOW GUSTS OF 30-40 KTS...MAINLY I95 CORRIDOR SEWD. TONIGHT...STRONGEST TSTMS HAVE OCCURRED PRIOR TO 00Z AND SO SHOULD BE VFR CIGS IN SCT SHOWERS WITH POSSIBLE ISO TSTM MVFR CONDS? IF PERSISTENT HEAVIER SHOWERS OCCUR...THEY WILL BE DE/MD AND FAR S NJ...POSSIBLY UP TO KMIV AND KACY. OVERALL LIGHT WIND. SATURDAY...VFR. ANY REMAINING CIGS NEAR 5000 FT IN THE MORNING ALONG THE COAST INCLUDING KACY CLEAR OUT BY 15Z. NW WIND G UNDER 15 KTS. OUTLOOK... SUNDAY - VFR CONDITIONS WITH NORTHWEST WINDS BECOMING SOUTHERLY BY THE AFTERNOON. EVENING THUNDERSTORMS COULD DEVELOP. MONDAY - COLD FRONT PASSAGE WITH WINDS OUT OF THE SOUTHWEST TURNING NORTHWEST. SHOWERS AND THUNDERSTORMS POSSIBLE. TUESDAY - VFR WITH SHOWERS ACROSS THE NORTH. WEDNESDAY - VFR WITH SHOWERS ACROSS THE NORTH. && .MARINE... WINDS AND SEAS ARE EXPECTED TO REMAIN BELOW SMALL CRAFT LEVELS THROUGH SATURDAY. OUTLOOK... SUB-ADVISORY CONDITIONS EXPECTED THROUGH THE OUTLOOK PERIOD. WEAK HIGH PRESSURE SATURDAY NIGHT THROUGH SUNDAY. ANOTHER COLD FRONT WILL MOVE THROUGH LATE ON SUNDAY NIGHT INTO MONDAY MORNING. HIGH PRESSURE THEN MOVES BACK INTO THE REGION FOR THE MIDDLE OF NEXT WEEK. SCATTERED SHOWERS WILL OCCUR AS AN UPPER LEVEL LOW KEEPS CLOSE TO THE REGION. && .HYDROLOGY... NMM VS ARW. NMM CAN BE A GOOD PRODUCT TO USE. THE 00Z/22 VSN APPEARS TO SIGNAL NE MD...N DE OR SNJ AS THE HEAVIEST WITH SPOTTY 3 TO 4 INCH AMTS THERE WHEREAS THE ARW FOCUSES IN JUST TO THE W OF NYC. MY TAKE IS THINK MORE UNSTABLE AIRMASS AND CLOSER TO ANY WEAK DIFFLUENT THICKNESS...IE...SOUTH OR IN THIS CASE S NJ TO NE MD. FOR THE MOST PART...ONE HOUR FLASH FLOOD GUIDANCE NUMBERS ARE NEAR 3 INCHES. THE EXCEPTIONS ARE MUCH OF NORTHWEST AND NORTH CENTRAL NEW JERSEY...WHERE THE NUMBERS DIP TO AS LOW AS 1.50 INCHES IN CENTRAL MORRIS COUNTY. THE OTHER VULNERABLE LOCATION IS CARBON COUNTY... WHERE ONE HOUR NUMBERS ARE AS LOW AS TWO INCHES. GIVEN THE CONVECTIVE NATURE OF THE HEAVY RAIN...AND THE DIFFICULTY DETERMINING THE LOCATION OF THE HEAVIEST RAIN...WE ILL FORGO THE FLASH FLOOD WATCH OPTION THIS MORNING...BUT CONTINUE TO MENTION HEAVY RAIN IN THE FORECAST. && .RIP CURRENTS... AWARENESS. PART OF RIP RISK PROBLEM MAY BE THE WARM SEA SURFACE TEMPERATURES THAT ENCOURAGE MANY TO GO SWIMMING ON THESE HOT DAYS. DOING SO... AT UNGUARDED BEACHES OR NEAR ANY JETTY OR PIER CAN BE LIFE THREATENING IS NOT ADVISED...EVEN ON A LOW RISK DAY. THE SEA SURFACE TEMPERATURES ARE WELL ABOVE NORMAL /AROUND 5 TO 9F DEGREES/ DUE TO THE RESIDUAL EFFECT OF LAST WINTERS EXCESSIVE WARMTH AND THE LACK OF A PERSISTENT BERMUDA HIGH SO FAR THIS YEAR A BERMUDA HIGH WOULD PROMOTE UPWELLING WITHIN AND NEAR THE COASTAL SURF ZONE AS EKMAN TRANSPORT REMOVES WARM SURFACE WATER SEAWARD. IN THIS SITUATION THIS WARM ANOMALY MAY CONTINUE INDEFINITELY UNTIL THE PATTERN CHANGES. && .CLIMATE...
