The episode as NWS PHI wrote it up.
A slow southward moving cold front located over the Philadelphia Delaware Valley during the morning of June 3rd helped trigger severe thunderstorms in northern Delaware during that evening.
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 2, 4:52 PM EST, 48 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 552 PM EDT TUE JUN 2 2009 .SYNOPSIS... A STATIONARY FRONT EXTENDED FROM SOUTHERN NEW JERSEY ACROSS DELMARVA. LOW PRESSURE FROM THE WEST WILL MOVE ALONG THE FRONT WEDNESDAY AND WEDNESDAY NIGHT WITH THE CIRCULATION FROM THE LOW PUSHING THE FRONT SOUTH AFTER THE LOW MOVES EAST WED NIGHT. HIGH PRESSURE WILL THEN BUILD ACROSS NEW ENGLAND THURSDAY AND FRIDAY WHILE THE OLD FRONTAL SYSTEM IS STATIONARY OVER SOUTHEAST VIRGINIA. A COLD FRONT FROM THE NORTHWEST SHOULD MOVE ACROSS THE MIDDLE ATLANTIC STATES SUNDAY AND THEN BECOME STATIONARY ON MONDAY. && .NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... THE FORECAST HAS BEEN UPDATED TO DROP THE SEVERE THUNDERSTORM WATCH. OTHERWISE, SOME MORE SHOWERS AND TSTMS ARE POSSIBLE LATE TONIGHT AS SHORT WAVES MOVE THROUGH FROM THE WEST. && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY/... DUE TO THE PROXIMITY OF THE FRONT OVER DELMARVA AND LOW PRESSURE MOVING ALONG THE FRONT, THERE COULD BE SHOWERS AND TSTMS WEDNESDAY...MAINLY SOUTH. OVER THE NORTHERN AREAS IT WILL BE MORE STABLE AND DRIER BUT STILL THE POSSIBILITY OF SHOWERS. AFTER THE LOW MOVES EAST OF THE AREA LATE WED NIGHT...THE FRONT SHOULD DROP FARTHER TO THE SOUTH AND ALLOW MORE DRYING OVER THE NORTHERN AREAS. THIS MEANS, IMPROVED CONDITIONS AND A DRY FORECAST NORTH THURSDAY, BUT STILL A CHANCE OF SHOWERS OR RAIN SOUTH DUE TO OVERRUNNING AND NE BLYR FLOW. DEPENDING ON WHERE THE FRONTAL SYSTEM IS LOCATED, THERE COULD BE SOME TSTMS THAT GO SEVERE. IF SEVERE TSTMS DO DEVELOP, THE AREAS TO THE SOUTH OF PHL WOULD HAVE A BETTER CHANCE OF SEEING THEN THAN TO THE NORTH. IN GENERAL A BLEND OF MAV/MET TEMPS WERE USED. ON THURSDAY, VERY COOL NE FLOW WILL COVER THE REGION AND TEMPERATURES PROBABLY WONT HIT 70 WITH THE SHORE STRUGGLING TO PERHAPS GET TO 65. && .LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/... CONFIDENCE IN THE LONG RANGE FORECAST IS NOT HIGH. ON FRIDAY...DRY WEATHER IS ANTICIPATED NORTH, BUT THE OLD FRONT AND APPROACHING LOW PRESSURE FROM THE SOUTH COULD BRING RAIN TO THE SOUTHERN PARTS OF THE AREA. ON SATURDAY...THE FRONT TO THE SOUTH RETREATS BACK TO THE SOUTH AND ANOTHER FRONT APPROACHES FROM THE NORTH. RIGHT NOW I WILL GO OPTIMISTIC WITH A DRY FCST. SUNDAY AND SUNDAY NIGHT...THE FRONT MOVES OVER THE AREA AND STALLS. THIS MEANS ANOTHER THREAT OF SHOWERS AND PERHAPS TSTMS. MONDAY...SHOWERS AND TSTMS ARE POSSIBLE WITH THE FRONT ACROSS THE REGION. TUESDAY...A NEW COLD FRONT MOVES DOWN FROM THE NW WITH PSBL SHOWERS AND TSTMS. && .AVIATION /22Z TUESDAY THROUGH SUNDAY/... THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY AND SURROUNDING AREAS. A WEATHER DISTURBANCE ROLLING ACROSS EASTERN PENNSYLVANIA THIS AFTERNOON WILL CONTINUE TO SLIDE TO THE EAST THROUGH EARLY THIS EVENING. SOME SHOWERS AND THUNDERSTORMS HAVE DEVELOPED ACROSS PARTS OF EASTERN PENNSYLVANIA. KRDG AND KABE WILL HAVE ACTIVITY AT LEAST IN THE VICINITY FOR A LITTLE WHILE LONGER. ELSEWHERE, SOME SHOWERS OR THUNDERSTORMS AT LEAST IN THE VICINITY THEREFORE WE CONTINUE TO HIGHLIGHT THIS IDEA WITH A VCSH AND CB DESCRIPTORS. RADAR DATA WILL CONTINUE TO BE MONITORED AND AMENDMENTS WILL BE ISSUED TO FINE TUNE THE TIMING. SOME STORMS COULD PRODUCE HEAVY RAIN AND GUSTY WINDS FOR A TIME, WHICH WOULD TEND TO LOWER CEILINGS TO AT LEAST MVFR LOCALLY. FOR TONIGHT, ANY ACTIVITY IS EXPECTED TO BE MOSTLY CONFINED TO THE EVENING HOURS THEN SOME MID LEVEL CLOUDS LINGER. THE LOW-LEVEL MOISTURE INCREASES THROUGH TONIGHT ESPECIALLY THE FARTHER SOUTH ONE GOES, THEREFORE WITH LIGHTER WINDS SOME FOG IS POSSIBLE TONIGHT AND EARLY WEDNESDAY MORNING. AS OF NOW, WE DID NOT HIT THE FOG POTENTIAL TO HARD AND ONLY CARRIED SUB-VFR CEILINGS WITH THE FOG AT KMIV AND KACY GIVEN BETTER LOW-LEVEL MOISTURE IN THOSE AREAS. ANOTHER DISTURBANCE MAY CROSS THE AREA SOMETIME TONIGHT, POSSIBLY TOUCHING OFF SOME MORE SHOWERS /ISOLATED THUNDER/. A COLD FRONT WILL BE SETTLING ACROSS OUR AREA TONIGHT AND WEDNESDAY, HOWEVER THERE IS UNCERTAINTY ON EXACTLY WHERE THE POSITION OF THIS FRONT WILL BE. DESPITE THE SURFACE WINDS LOOKING FAIRLY LIGHT TONIGHT AND WEDNESDAY MORNING, THE DIRECTION MAY BE TRICKY DEPENDING ON THE PLACEMENT OF THE FRONT. FOR SOME TERMINALS, WE WENT MORE TOWARD A LIGHT AND VARIABLE WIND. ON WEDNESDAY, THE BOUNDARY WILL BE IN THE VICINITY AND WITH ANOTHER WEATHER DISTURBANCE MOVING THROUGH, SOME SHOWER AND THUNDERSTORM ACTIVITY IS EXPECTED ESPECIALLY IN THE AFTERNOON. GIVEN THE LOWER CONFIDENCE REGARDING SHOWER/STORM INITIATION, WE ONLY CARRIED A VCTS AND CB MENTION AT KPHL AFTER 18Z /30-HOUR TAF/. WINDS LOOK TO BE NORTHEAST BUT MAY TEND TO SHIFT TO THE SOUTHEAST ESPECIALLY FROM KPHL METRO AREA ON EASTWARD. AGAIN, THE WINDS WILL BE DEPENDENT ON WHERE THE FRONT ACTUALLY BECOMES SITUATED. OUTLOOK... SOME SHOWERS AND THUNDERSTORMS LOOK TO BE AROUND THROUGH WEDNESDAY NIGHT AS A FRONTAL BOUNDARY LURKS NEARBY. A DISTURBANCE LOOKS TO TRACK ALONG THE FRONT THURSDAY, WHICH MAY ALLOW FOR A MORE ORGANIZED RAIN WITH EMBEDDED THUNDERSTORM CHANCE. THIS POTENTIAL MAY LINGER INTO FRIDAY AS WELL, THEN WE REMAIN BETWEEN TWO FRONTAL BOUNDARIES LATER FRIDAY AND SATURDAY. HOWEVER, A COLD FRONT TO OUR NORTHWEST LOOKS TO SETTLE INTO OUR AREA SATURDAY NIGHT INTO SUNDAY. && .MARINE... THE FORECAST HAS BEEN UPDATED TO DROP THE SEVERE THUNDERSTORM WATCH. A COLD FRONT WILL SETTLE ACROSS OUR AREA TONIGHT AND LINGER IN THE VICINITY THROUGH WEDNESDAY NIGHT. A WIND SHIFT WILL ACCOMPANY THIS FRONT AS IT SETTLES FROM NORTH TO SOUTH. THERE IS LOWER CONFIDENCE REGARDING THE EXACT PLACEMENT OF THIS FRONT WHICH WILL GOVERN THE BEHAVIOR OF THE SURFACE WINDS. A DISTURBANCE WILL MOVE ACROSS THE AREA LATE THIS AFTERNOON AND THIS EVENING AND BE ACCOMPANIED BY SOME SHOWER AND THUNDERSTORM ACTIVITY. SOME STORMS COULD BE LOCALLY STRONG/SEVERE WITH GUSTY WINDS. ANOTHER DISTURBANCE IS FORECAST TO CROSS THE AREA DURING WEDNESDAY. THIS WILL TEND TO INITIATE ADDITIONAL SHOWERS AND THUNDERSTORMS, WITH SOME STORMS ONCE AGAIN POTENTIALLY BECOMING STRONG TO SEVERE. WHILE THE WINDS AND SEAS OVERALL ARE EXPECTED TO REMAIN BELOW ADVISORY CRITERIA, CONDITIONS CAN BE LOCALLY GUSTY/ROUGH IN AND NEAR THUNDERSTORMS THROUGH WEDNESDAY. AN AREA OF LOW PRESSURE TRACKING ALONG THE FRONT THURSDAY INTO FRIDAY MAY PRODUCE A MORE WIDESPREAD PERIOD OF RAIN AND EMBEDDED THUNDERSTORMS. OUR AREA THEN REMAINS BETWEEN TWO FRONTAL BOUNDARIES AND THE ONE TO OUR NORTHWEST IS FORECAST TO ARRIVE LATE SATURDAY INTO SUNDAY. THE LATEST WAVEWATCH GUIDANCE HAS THROTTLED BACK ON THE SEAS SOME THROUGH THURSDAY WITH NOW NOT REACHING 5 FEET UNTIL EARLY FRIDAY MORNING AT BUOY 44009. THERE DOES NOT APPEAR TO BE MUCH OF A PRESSURE GRADIENT, THEREFORE WINDS ARE EXPECTED TO REMAIN BELOW ADVISORY CRITERIA. EVENTUALLY, A NORTHEASTERLY WIND LATER THIS WEEK COULD BE ENOUGH TO BUILD SEAS TO 5 FEET OR A LITTLE ABOVE. AS A RESULT, NO HEADLINES WILL BE ISSUED AT THIS TIME. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...NONE. NJ...NONE. DE...NONE. MD...NONE.
