The episode as NWS PHI wrote it up.
A squall line of strong thunderstorms moved through Delaware during the morning of June 9th. Lightning from the thunderstorms caused a couple of house fires in Rehoboth Beach and Dagsboro.
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 9, 8:08 AM EST, 22 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 908 AM EDT TUE JUN 9 2009 .SYNOPSIS... A FRONTAL BOUNDARY WILL REMAIN ACROSS OUR REGION TODAY INTO WEDNESDAY. THIS FRONT SHOULD LIFT NORTHWARD AS A WARM FRONT LATER WEDNESDAY INTO THURSDAY AS LOW PRESSURE NEARS OUR REGION. THIS LOW WILL CROSS THE AREA THURSDAY INTO FRIDAY, WITH AN ASSOCIATED COLD FRONT FINALLY SWINGING THROUGH OUR REGION FRIDAY MORNING. HIGH PRESSURE IS THEN FORECAST TO GRADUALLY BUILD TOWARD OUR REGION SATURDAY AND SUNDAY. && .NEAR TERM /THROUGH TONIGHT/... THE DENSE FOG ADVISORY WAS ALLOWED TO EXPIRE AT 9 AM EDT AND WE HAVE UPDATED ALL PUBLIC PRODUCTS TO REFLECT THIS. VERY EARLY ON, THE NAM HAD BOTH THE INSTABILITY TO THE WEST AND THE MARINE FLOW COMING IN OFF THE OCEAN TO THE EAST, AND WE STARTED BY FAVORING THAT MODEL, WHICH IS TO SAY WE DID NOT LIFT THE WARM FRONT THROUGH THE ENTIRE AREA. THE NAM ALSO WAS SUPPORTING SPCS DEPICITION OF A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR TODAY OVER ABOUT THE WESTERN HALF OF OUR AREA. THERE WAS AN APPROACHING UPPER JETLET, AN APPROACHING SHORT WAVE THIS MORNING WITH PERHAPS ANOTHER WEAKER ONE LATER THIS AFTERNOON, SOME VERY GOOD CAPES AS ONE MOVED WEST /INCLUDING CAPES IN THE 0 TO -20 DEG C PART OF THE SOUNDINGS/, DIRECTIONAL SHEAR, ALBEIT WITH FAIRLY WEAK SPEEDS IN THE LOWER LAYERS, AND SOME ROBUST MOISTURE WITH MORNING VALUES IN EXCESS OF 1.5 INCHES. SOME OF THAT MOISTURE LOOKED TO GET TAKEN EAST BY THE FIRST SHORT WAVE, BUT VALUES STAYED ABOVE 1.25 THROUGH THE DAY. HPC WAS CONCERNED THAT THE NAM WAS WEAK WITH THE SOUTHERN EDGE OF ENERGY COMING THROUGH TODAY, AND STILL THE NAM DID SHOW DECENT LOWER LEVEL FRONTOGENESIS MOVING IN THIS AFTERNOON, SO WE WERE NOT AT ALL CERTAIN THAT THE THREAT TO OUR WESTERN COUNTIES WOULD DIMINISH WITH THE PASSING OF THE FIRST IMPULSE. WE STARTED BY CARRYING ENHANCED WORDING WEST AND CENTRAL WITH NO REGARD TO TIMING. WE MENTIONED HAIL, WIND, LIGHTNING AND HEAVY DOWNPOURS. TEMPERATURES LEANED TOWARD THE MET EAST /ESPECIALLY NORTHEAST/ AND TOWARD THE MAV WEST CENTRAL AND SOUTHWEST. && .SHORT TERM /WEDNESDAY THROUGH WEDNESDAY NIGHT/... THE NAM HOLDS TOUGH WITH THE HIGH TO THE NORTHEAST AND THE ONSHORE FLOW TONIGHT. THE GFS AND THE ECMWF DEVELOP A LOW NEAR THE DELMARVA BY THE END OF THE NIGHT, AND SO ALSO EVENTUALLY DEVELOP AN EASTERLY FLOW. THE THREE MODELS HAVE VARIOUS DEPICITIONS OF ENERGY COMING OVER A WEAKLY BUILDING RIDGLET, AND WEVE BASICALLY GONE WITH A PRECIP FORECAST THAT STARTS WITH ASSUMED PERSISTENCE /FROM WHAT WE ARE FORECASTING FOR THE FIRST PERIOD/ AND ENDS WITH CLIMATOLOGY /LOW POPS/. AGAIN, OUR TEMPERATURES LEAN MET NORTHEAST AND THEN BLEND MET AND MAV MOVING FURTHER SOUTHWEST. BY WEDNESDAY, WE WOULD LIKE TO FAVOR CLIMATOLOGY IN THAT IT WOULD BE HARD TO KEEP THE WARM FRONT AT BAY WITH SUCH A HIGH SUN ANGLE AND A PROGRESSIVE /SLOWLY PROGRESSIVE/ SURFACE HIGH TO THE NORTHEAST, BUT SAID HIGH KEEPS GETTING STRONGER ON ALL MODELS. WE COULDNT FIND A TRIGGER FOR CONVECTION AT THE MID LEVELS AND SO OUR POPS ARE LOW FOR NOW, BUT WE DID GO CLOSE TO PERSISTENCE VIS A VIS TODAY ON TEMPERATURES. WITH A SYSTEM APPROACHING FROM THE WEST ON WEDNESDAY NIGHT, WE BROUGHT POPS BACK IN. THE NAM LOOKS OVERDONE WITH THE STRENGTH OF THIS SYSTEM, SO WE DID NOT RAISE MINIMUM TEMPERATURES BASED ON ITS STRONG H925 FLOW AT THIS POINT BUT RATHER MAINTAINED CONTINUITY. && .LONG TERM /THURSDAY THROUGH MONDAY/... BY THURSDAY, THE WARM FRONT WILL BEGIN LIFTING BACK NORTHWARD, WITH AN AREA OF LOW PRESSURE LIFTING TOWARD THE AREA OVERNIGHT THURSDAY INTO FRIDAY. FINALLY THE COLD FRONT WILL MOVE THROUGH THE AREA OVERNIGHT THURSDAY INTO FRIDAY. THIS WILL HELP TO KEEP A CHANCE OF SHOWERS AND THUNDERSTORMS ACROSS THE AREA FROM THURSDAY INTO FRIDAY. WE COULD SEE SOME STRONG STORMS DEPENDING OF THE TRACK OF THE WARM FRONT AND LOW PRESSURE SYSTEM AND IF WE REMAIN IN THE WARM SECTOR LONG ENOUGH. EITHER WAY, WE WILL LIKELY SEE SOME HEAVY RAIN WITH SOME SHOWERS/THUNDERSTORMS. BY LATE FRIDAY AND INTO THE WEEKEND, AFTER THE COLD FRONT MOVES THROUGH, HIGH PRESSURE WILL BUILD IN. THIS WILL PROVIDE FOR A NICE WEEKEND. WITHOUT ANY STRONG WARM OR COLD AIR ADVECTION, TEMPERATURES SHOULD REMAIN COMFORTABLE. IN FACT, TEMPERATURES THROUGHOUT THE EXTENDED ARE EXPECTED TO BE CLOSE TO AVERAGE FOR THIS TIME OF YEAR. && .AVIATION /13Z TUESDAY THROUGH SATURDAY/... THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY AND SURROUNDING AREAS. A RATHER TRICKY FORECAST AS A FRONTAL BOUNDARY IS DRAPED FROM FAR SOUTHERN NEW JERSEY BACK TO NEAR KILG THEN JUST SOUTHWEST OF KRDG. LOW PRESSURE IS FORECAST TO TRACK WELL TO OUR WEST AND NORTH TODAY INTO TONIGHT, WHICH MAY NOT ALLOW THE AFOREMENTIONED SURFACE BOUNDARY IN OUR AREA TO WORK VERY FAR NORTHWARD. THE MOIST ONSHORE FLOW IS RATHER EVIDENT IN SURFACE OBSERVATIONS AS WELL AS SATELLITE IMAGERY BY A SOLID STRATUS DECK ALONG WITH SOME FOG. THIS STRATUS DECK HAS BEEN GRADUALLY SLIDING WESTWARD WITH TIME AND ALL OUR TERMINALS ARE EXPECTED TO HAVE AT LEAST SOME IFR TO LIFR CEILINGS. THERE ARE DIFFERENCES AMONG THE COMPUTER MODELS ON THE EXTENT OF THE LOWER CONDITIONS AND HOW LONG THEY LAST TODAY. WE LEANED MORE TOWARD THE SLOWER APPROACH AS THE TRACK OF THE MAIN LOW PRESSURE SYSTEM FAR REMOVED FROM OUR AREA COULD BE ENOUGH TO MAINTAIN A MORE ONSHORE FLOW. A POSSIBLE CONCERN IS THAT THE STRONG JUNE SUNSHINE MAY BE ABLE TO MIX OUT THE LOW-LEVEL MOISTURE ENOUGH, ALLOWING CEILINGS TO RISE MORE THAN ANTICIPATED. THE LOWER CEILINGS HELD ON LONGER THAN INITIALLY THOUGHT YESTERDAY, THEREFORE WE DID NOT WANT TO RUSH THE IMPROVEMENTS GIVEN A MORE WIDESPREAD SCENARIO THIS MORNING. WITH THE BOUNDARY IN THE AREA COMBINED WITH UPPER-LEVEL ENERGY AND A SURFACE TROUGH ARRIVING FROM THE WEST THROUGH THE DAY, SHOWERS AND THUNDERSTORMS ARE EXPECTED. WHILE SOME ACTIVITY WILL BE AROUND THIS MORNING ESPECIALLY KRDG AND KABE, PERHAPS MORE WIDESPREAD SHOWERS AND STORMS OCCUR FROM ABOUT MIDDAY ON FROM WEST TO EAST. TIMING THE ACTIVITY IS CHALLENGING, HOWEVER THIS WOULD CHANGE ONCE THE ACTIVITY INITIATES AND BECOMES MORE ORGANIZED. WE ARE MONITORING A ROBUST LINE OF CONVECTION EXITING OUT OF CENTRAL PENNSYLVANIA AND HEADED FOR THE KRDG AND KABE AREAS. FOR NOW, WE CONTINUED WITH VCSH/VCTS AND THE CB DESCRIPTOR AND WILL ISSUE AMENDMENTS AS NEEDED TO FINE TUNE THE DETAILS. IF THE FRONTAL BOUNDARY IS SLOWER IN LIFTING NORTHWARD AS A WARM FRONT THROUGH THE DAY, THIS MAY LIMIT THE SEVERITY OF THE THUNDERSTORMS. EITHER WAY, THERE IS PLENTY OF MOISTURE IN THE ATMOSPHERE, THEREFORE LOCALLY HEAVY RAIN WOULD TEND TO REDUCE THE VISIBILITY AT TIMES AND FREQUENT LIGHTNING IS EXPECTED WITH MANY STORMS. SHOWERS AND THUNDERSTORMS ARE EXPECTED TO CONTINUE FOR THIS EVENING THEN DIMINISH WITH TIME. A FRONTAL BOUNDARY LOOKS TO MEANDER IN OUR VICINITY TONIGHT, AND THIS MAY TEND TO KEEP THE CLOUD BASES LOWER. IF THE CEILINGS ARE ABLE TO IMPROVE, THEY MAY TEND TO LOWER ONCE AGAIN IN THE EVENING AS PLENTY OF LOW-LEVEL MOISTURE REMAINS. OUTLOOK... AREAS OF LOW CLOUDS AND FOG WILL BE POSSIBLE OVERNIGHT AND WEDNESDAY MORNING AS A PESKY BOUNDARY LOOKS TO LINGERS NEAR OUR AREA. WE MAY BE ABLE TO SQUEEZE IN A DRY DAY WEDNESDAY BEFORE THE NEXT LOW PRESSURE SYSTEM MOVES IN FOR THURSDAY. THIS LOOKS TO BRING ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS THURSDAY INTO FRIDAY BEFORE A COLD FRONT SETTLES TO OUR SOUTH AND EAST. HIGH PRESSURE THEN GRADUALLY BUILDS TOWARD OUR AREA LATER FRIDAY AND SATURDAY. && .MARINE... A FRONTAL BOUNDARY IS NEARLY STALLED ACROSS OUR SOUTHERN WATERS WITH AN EASTERLY FLOW TO ITS NORTH. WHILE THERE IS NO REAL STRONG PRESSURE GRADIENT, THE PLACEMENT OF THE SURFACE BOUNDARY WILL GOVERN THE WIND DIRECTION. THERE ARE DIFFERENCES AMONG THE COMPUTER MODELS ON HOW FAR NORTH THIS BOUNDARY LIFTS THROUGH WEDNESDAY, AND WE ARE LEANING MORE TOWARD THE SLOWER SOLUTION GIVEN THE MAIN SURFACE LOW BEING FAR REMOVED FROM OUR AREA TODAY AND TONIGHT. THIS WILL KEEP AN EASTERLY COMPONENT TO THE WIND LONGER ACROSS THE NORTHERN COASTAL WATERS. WE ARE ANTICIPATING WINDS TO BE ABOUT 10 KNOTS GIVEN THE FAIRLY WEAK PRESSURE GRADIENT THROUGH WEDNESDAY. AS LOW PRESSURE APPROACHES ON THURSDAY THEN SLIDES NEARBY THURSDAY NIGHT, THE LOW-LEVEL WIND FIELD IS FORECAST TO INCREASE FROM THE SOUTH AND SOUTHWEST. THE FORECAST SOUNDINGS DO INDICATE A LOW-LEVEL INVERSION HOLDING WITHIN THE WAA REGIME. THIS WOULD TEND TO LIMIT THE STRONGER WINDS ALOFT FROM REACHING THE SURFACE. WE WILL CONTINUE TO GO IN THIS DIRECTION. THE INCREASED FLOW THOUGH WILL BUILD THE SEAS SOME, HOWEVER WAVEWATCH ONLY TOPS SEAS TO 5 FEET LATER THURSDAY FOR A SHORT PERIOD OF TIME. FOR NOW, WE CONTINUED WITH THE IDEA OF CAPPING THE SEAS AT 4 FEET GIVEN THE UNCERTAINTY WITH THE DETAILS AND THE LACK OF A MUCH STRONGER GRADIENT. HOWEVER, WINDS AND SEAS WILL BE LOCALLY HIGHER NEAR THUNDERSTORMS. THE SYSTEM LOOKS TO FINALLY BE SLIDING TO OUR EAST FRIDAY MORNING WHICH WILL PULL A COLD FRONT THROUGH. HIGH PRESSURE IS FORECAST TO GRADUALLY BUILD TOWARD OUR AREA SATURDAY, HOWEVER A FRONTAL BOUNDARY MAY NOT BE TO FAR AWAY TO OUR SOUTH. OVERALL, CONDITIONS CONTINUE TO BE FORECAST BELOW SMALL CRAFT ADVISORY CRITERIA THROUGH THE PERIOD. && .HYDROLOGY... FLASH FLOOD AND HEADWATER GUIDANCE ONE HOUR VALUES START TO GET EXCITED AT AROUND 1.5 INCHES, AND WE DIDNT THINK THAT WOULD HAPPEN ON A WIDE ENOUGH SCALE TO ISSUE ANY WATCHES. HOWEVER, THE PARAMETERS MENTIONED ABOVE IN THE NEAR TERM SECTION MAY CAUSE A FEW CELLS TO DROP ENOUGH RAIN TO CAUSE LOCALIZED FLOODING AND WE HAVE MENTIONED THIS IN THE HWO. && .PHI WATCHES/WARNINGS/ADVISORIES...
