The episode as NWS PHI wrote it up.
An approaching cold front triggered a series of thunderstorms through the Eastern Shore during the daytime hours of the 25th.
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 Aug 25, 5:28 AM EST, 2 hours 32 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 628 AM EDT THU AUG 25 2011 .SYNOPSIS... A COLD FRONT WILL MOVE INTO OUR REGION LATER THIS AFTERNOON, THEN TEND TO STALL NEAR THE COAST TONIGHT AND FRIDAY. HURRICANE IRENE WILL THEN MOVE NORTHWARD DURING THE WEEKEND, HOWEVER HOW CLOSE TO THE COAST CARRIES SOME UNCERTAINTY. THE STORM IS FORECAST TO EXIT TO OUR NORTH AND NORTHEAST LATER SUNDAY WITH A FRONTAL BOUNDARY SHIFTING TO OUR EAST INTO MONDAY. A STRENGTHENING AREA OF HIGH PRESSURE GENERALLY BUILDS IN FOR TUESDAY AND WEDNESDAY. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... SHOWERS AND THUNDERSTORMS IN ADVANCE OF AN APPROACHING COLD FRONT EXTENDED ACROSS EASTERN NEW YORK, CENTRAL AND WESTERN PENNSYLVANIA AND SOUTHERN OHIO AT 630 AM. THE CONVECTION REMAINED RATHER ROBUST DURING THE NIGHT. IT MAY WEAKEN A BIT THIS MORNING BEFORE BECOMING REINVIGORATED DURING THE MIDDAY HOURS. IT APPEARS AS THOUGH THE CONVECTION WILL MAKE ITS WAY ACROSS MUCH OF EASTERN PENNSYLVANIA AND NORTHERN NEW JERSEY DURING THE AFTERNOON AND EARLY EVENING. IT SHOULD AFFECT MUCH OF SOUTHERN NEW JERSEY AND THE UPPER DELMARVA MAINLY DURING THE EVENING HOURS. WITH THE INCREASED LOW LEVEL MOISTURE IN THE SOUTHERLY FLOW, CAPE VALUES SHOULD RISE INTO THE 1500 TO 2000 J/KG RANGE FOR THIS AFTERNOON IN OUR REGION. WITH THE INSTABILITY, SOME OF THE THUNDERSTORMS THIS AFTERNOON INTO THIS EVENING MAY BECOME SEVERE. THE STORM PREDICTION CENTER HAS MAINTAINED OUR REGION UNDER THEIR SLIGHT RISK DESIGNATION FOR TODAY. WE WILL MENTION THE POSSIBILITY OF GUSTY WINDS, HEAVY RAIN AND FREQUENT LIGHTNING WITH THE STORMS. WITH PRECIPITABLE WATER VALUES GETTING UP AROUND 2 INCHES THIS AFTERNOON INTO THIS EVENING, SOME SPOTS WILL LIKELY RECEIVE HEAVY RAIN. WE HAVE CONSIDERED A FLOOD WATCH. HOWEVER, OUR CURRENT THINKING IS THAT ANY STREAM AND RIVER FLOODING WILL NOT BE WIDESPREAD ENOUGH TO WARRANT A WATCH AT THIS POINT. THERE MAY BE A FAIR AMOUNT OF POOR DRAINAGE AREA FLOODING. MAXIMUM TEMPERATURES SHOULD RANGE FROM THE MIDDLE AND UPPER 70S IN THE POCONOS WHERE THERE WILL BE MORE CLOUD COVER AND AN EARLIER ONSET OF THE PRECIPITATION TO NEAR 90 DEGREES IN EXTREME SOUTHEASTERN PENNSYLVANIA, SOUTHERN NEW JERSEY AND THE UPPER DELMARVA. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 AM FRIDAY/... A COLD FRONT FROM THE NORTHWEST WILL BE SLOW TO MOVE THROUGH OUR REGION TONIGHT. THUNDERSTORMS WILL LIKELY LINGER IN SOUTHERN NEW JERSEY, DELAWARE AND NORTHEASTERN MARYLAND THIS EVENING. WITH A FAIR AMOUNT OF LOW LEVEL MOISTURE EXPECTED TO REMAIN IN OUR REGION LATE TONIGHT, WE HAVE MENTIONED PATCHY FOG. TEMPERATURES ARE FORECAST TO DROP TO AROUND 60 DEGREES IN THE POCONOS AND FAR NORTHERN NEW JERSEY. READINGS MAY FALL ONLY TO AROUND 70 IN SOUTHEASTERN PENNSYLVANIA, SOUTHERN NEW JERSEY AND THE UPPER DELMARVA. && .LONG TERM /FRIDAY THROUGH WEDNESDAY/... THE SATURDAY AND SUNDAY FORECAST HAS BEEN ADJUSTED BASED ON THE NEW 5 AM TRACK FORECAST FROM THE NHC. IT LOOKS LIKE THE TRACK HAS EDGED CLOSER TO THE COAST AND THE WIND FORECAST HAS RESPONDED AS A RESULT. THE WIND GUSTS WERE RUN MAINLY USING A NON-MIXING TYPE TOOL WITH A CAP OF ABOUT 90 KNOTS FOR NOW. THE MIXING INCORPORATED WIND GUST TOOL HAS BEEN GIVING REALLY RAMPED UP VALUES. THE MAIN FOCUS FOR THIS PERIOD CONTINUES TO BE THE TRACK AND IMPACTS OF HURRICANE IRENE. WE WANT TO STRESS THAT IT IS IMPORTANT TO NOT FOCUS ON THE EXACT FORECAST TRACK OF THE STORM, ESPECIALLY FOR THE LONGER RANGE, SINCE ERRORS ARE AROUND 200 MILES /THE STORM IS NOT A SINGLE POINT/. WE EXPECT IMPACTS FROM THIS HURRICANE ACROSS THE CWA WITH THE PEAK GENERALLY OCCURRING SATURDAY NIGHT THROUGH ABOUT MIDDAY SUNDAY. THE EXACT TRACK OF THE HURRICANE AS IT MOVES BY OUR REGION WILL DETERMINE THE OVERALL IMPACTS, HOWEVER THERE REMAINS A RATHER ELEVATED POTENTIAL FOR SERIOUS IMPACTS ON OUR AREA FROM THIS HURRICANE. EVERYONE SHOULD BE PREPARING FOR THIS LARGE STORM AS NOW IS THE TIME. HAVE A PLAN IN PLACE. WE BEGIN ON FRIDAY AS GENERALLY THE CALM BEFORE THE STORM. A FRONTAL BOUNDARY FROM THE NEAR/SHORT TERMS IS ANTICIPATED TO BE STALLED PROBABLY NEAR THE COAST. THIS MAY TURN INTO A COASTAL FRONT OR WARM FRONT AS THE ONSHORE FLOW BEGINS TO INCREASE WELL AHEAD OF IRENE. THE ADVECTION OF WARM AND INCREASINGLY MOIST AIR IN CONJUNCTION WITH POTENTIALLY A ZONE OF LOW-LEVEL CONVERGENCE MAY ALLOW FOR SOME CONVECTION TO DEVELOP ESPECIALLY ACROSS THE SOUTHEASTERN PORTION OF THE CWA. WE WILL MAINTAIN SOME LOW POPS FOR THIS REASON. SATURDAY AND SUNDAY IS THE TIME FRAME OF MOST CONCERN. THE MODEL GUIDANCE CONTINUES TO WIGGLE WEST TO EAST WITH THE TRACK OF HURRICANE IRENE AS IT TURNS NORTHWARD TOWARD THE NORTHEASTERN U.S. IT APPEARS THAT THE MAIN PLAYER IS THE UPPER-LEVEL TROUGH MOVING THROUGH THE NORTHERN TIER OF STATES. AN INITIAL TROUGH IS FORECAST TO LIFT OUT WITH SOME WEAKNESS LEFT BEHIND. A SECONDARY TROUGH THEN MOVES THROUGH THE GREAT LAKES AND SOUTHEASTERN CANADA SATURDAY INTO SUNDAY. THE FORWARD SPEED IN CONJUNCTION WITH THE TIMING AND AMPLIFICATION OF THE TROUGH IS CRUCIAL IN DETERMINING THE WESTERN EXTENT OF THE HURRICANES TRACK. THIS IS DANGEROUS AS A LATER TIMING IN THE TROUGH AMPLIFYING SOME MORE WILL TEND TO ALLOW THE HURRICANE TO TRACK CLOSER TO THE COAST. THERE ARE SEVERAL COMPUTER MODELS CONTINUING TO SHOW THE CLOSER LAND TRACK SCENARIO WHICH IS RATHER CONCERNING. THIS LOOKS TO BE A LARGE HURRICANE AS IT GOES BY OUR REGION, THEREFORE EVEN IF THE CENTER STAYS OFF THE COAST WE WILL STILL HAVE IMPACTS FROM IT. OUR WIND FORECAST IS BASED OFF OF THE GRIDDED WIND FIELD FROM THE OFFICIAL NATIONAL HURRICANE CENTER /NHC/ FORECAST. WE GENERALLY BASED OUR POPS MORE TOWARD A BLEND WHICH ENDS UP SIMILAR TO THE GFS. IF THE CENTER TRACKS FARTHER OFF THE COAST, THEN THERE MAY BE A RATHER TIGHT GRADIENT IN THE RAIN SHIELD ACROSS THE CWA FROM EAST TO WEST /LIKE THE 00Z CMC SHOWS/. EVERYTHING REMAINS ON THE TABLE WITH THIS HURRICANE, WHICH INCLUDES WIDESPREAD DAMAGING WINDS, TORRENTIAL RAIN, COASTAL FLOODING, DANGEROUS RIP CURRENTS/WAVES AND BEACH EROSION. INTERESTING TO NOTE IS THE DEVELOPMENT OF A STRONG 250 MB JET NORTH OF THE HURRICANE SATURDAY INTO SUNDAY, GENERALLY FROM THE EASTERN GREAT LAKES TO NORTHERN NEW ENGLAND. SOME OF THE MODELS INDICATE THAT THE ORIENTATION OF THIS JET IS SUCH THAT IRENE IS WITHIN THE RIGHT ENTRANCE REGION AS SHE TRACKS NORTHWARD. THIS SCENARIO COULD HELP WITH A POLEWARD UPPER-LEVEL OUTFLOW CHANNEL AND ASSIST IN THE INTENSITY OF THE SYSTEM AS A WHOLE. AS STATED BEFORE, LOTS TO IRON OUT WITH THE DETAILS AS IT DEPENDS ON THE EXACT TRACK OF THE CENTER. THE SYSTEM SHOULD BE PICKING UP FORWARD SPEED AS IT GAINES LATITUDE AND BECOMES EMBEDDED IN THE STRONGER WESTERLIES. THEREFORE, WE TAPERED THE POPS FROM SOUTH TO NORTH A BIT FASTER AS WE GO THROUGH SUNDAY AND SUNDAY NIGHT. THE PW VALUES FORECAST ACROSS THE REGION ARE RATHER IMPRESSIVE WITH 2.0-2.5 INCHES OVERSPREADING THE REGION LATE SATURDAY INTO SUNDAY. IF THE CENTER GETS CLOSE ENOUGH TO THE COAST, SOME GUIDANCE INDICATES THE PW VALUES INCREASE TO JUST OVER 3.0 INCHES. THIS AMOUNT OF MOISTURE IN THE ATMOSPHERE WILL LEAD TO EXCESSIVE RAINFALL RATES AND TOTALS. THIS COMBINED WITH ANY UPSLOPE ENHANCEMENT AND/OR LOCALLY ENHANCED CONVERGENCE WILL ADD TO THE RAIN RATES. THE INITIAL INFLUX OF THIS HIGHER MOISTURE CONTENT AIR ALONG WITH THE PRESENCE OF A COASTAL TYPE FRONT COULD LEAD TO BOUTS OF LOCALLY HEAVY DOWNPOURS WELL BEFORE THE HURRICANE GETS TO OUR LATITUDE. WE WILL CONTINUE TO CARRY A HEAVY RAIN MENTION IN THE FORECAST AND ALSO THE HAZARDOUS WEATHER OUTLOOK. IT APPEARS THE SEVERE WEATHER/TORNADO POTENTIAL IS ON THE LOW SIDE ALTHOUGH THIS STILL NEEDS TO BE MONITORED GIVEN THE LOW-LEVEL SHEAR ASSOCIATED WITH TROPICAL CYCLONES, ESPECIALLY IF IT TRACKS FURTHER WEST. FOR MONDAY, A MORE TRANQUIL TIME FRAME IS EXPECTED IN THE WAKE OF IRENE. WINDS WILL DIMINISH AS MONDAY PROGRESSES AND SUBSIDENCE AROUND IT SHOULD ALLOW FOR LESS CLOUDS. FOR TUESDAY AND WEDNESDAY, A WEAK SURFACE BOUNDARY AND UPPER-LEVEL TROUGH GENERALLY SLIDES ACROSS NEW ENGLAND. THERE DOES NOT APPEAR TO BE MUCH FORCING TO LATCH ONTO THIS FAR OUT, THEREFORE WE OPTED TO GO WITH A DRY FORECAST. && .AVIATION /12Z THURSDAY THROUGH MONDAY/... AT 1030Z, CONDITIONS WERE MAINLY VFR IN OUR REGION. HOWEVER, SOME MVFR CEILINGS HAD DEVELOPED AROUND KRDG, KABE AND KTTN IN THE SOUTHERLY FLOW. MAINLY VFR CONDITIONS ARE ANTICIPATED THIS MORNING WITH A SOUTH WIND AROUND 6 TO 10 KNOTS. BY LATE MORNING, WIND SPEEDS SHOULD INCREASE INTO THE 8 TO 12 KNOT RANGE WITH GUSTS NEAR 20 KNOTS AS THE ATMOSPHERE CONTINUES TO MIX. THUNDERSTORMS APPROACHING SLOWLY FROM THE WEST AND NORTHWEST MAY BEGIN TO AFFECT KRDG AND KABE DURING THE MIDDAY HOURS. THE THUNDERSTORMS ARE EXPECTED TO BECOME STRONG TO SEVERE AS THEY MAKE THEIR WAY THROUGH OUR REGION DURING THE AFTERNOON AND EVENING HOURS. AS A RESULT, AVIATION WILL LIKELY BE IMPACTED SIGNIFICANTLY. THE SHOWERS AND THUNDERSTORMS WILL BE SLOW TO PASS OFF THE COAST EARLY TONIGHT. A FAIR AMOUNT OF LOW LEVEL MOISTURE WILL BE LEFT IN THEIR WAKE. AS A RESULT, THERE MAY BE SOME LOW CLOUDS AND VISIBILITY RESTRICTIONS DUE TO FOG LATE TONIGHT. THE WIND SHOULD REMAIN GUSTY AND FROM THE SOUTH AND SOUTHWEST THIS AFTERNOON. WIND SPEEDS ARE ANTICIPATED TO DIMINISH FOR TONIGHT, EVEN WITH THE COLD FRONT EXPECTED TO DRIFT THROUGH OUR REGION AT THAT TIME. OUTLOOK... FRIDAY...A FRONTAL BOUNDARY SITUATED NEAR THE COAST MAY HELP FOCUS SOME SHOWERS AND THUNDERSTORMS MAINLY IN THE AFTERNOON AND AT NIGHT. OVERALL, SHOULD BE MAINLY VFR WITH THE EXCEPTION WITH ANY CONVECTION. A SOUTH TO SOUTHEAST WIND UP TO 10 KNOTS IS ANTICIPATED. SATURDAY AND SUNDAY...HURRICANE IRENE IS FORECAST TO TRACK NORTHWARD AND MOVE NEAR OUR AREA. WHILE THERE IS UNCERTAINTY WITH THE EXACT TRACK, THERE CONTINUES TO BE AN INCREASED THREAT TO OUR AREA. AT THIS TIME, IT APPEARS WIDESPREAD SUB-VFR CONDITIONS WILL SET IN WITH GUSTY ONSHORE WINDS EVENTUALLY TURNING NORTH AND THEN NORTHWEST AS THE STORM MOVES ON BY. AS WE GET CLOSER TO THE EVENT AND THE TRACK BECOMES MORE CERTAIN, WE WILL BE ABLE TO BE MORE SPECIFIC WITH THE DETAILS. BOTTOM LINE IS THE INCREASED POTENTIAL FOR SIGNIFICANT IMPACTS TO OUR TERMINALS, WHICH INCLUDES STRONG WINDS AND TORRENTIAL RAIN. THE STORM SHOULD EXIT TO OUR NORTHEAST LATER SUNDAY WITH IMPROVING CONDITIONS. MONDAY...A CALMER TIME FRAME AS IRENE IS WELL TO OUR NORTH AND NORTHEAST AND WEAKENING. THIS WILL RESULT IN ANY ELEVATED NORTHWESTERLY WINDS DIMINISHING THROUGH THE DAY. && .MARINE... A SOUTHERLY WIND IS EXPECTED TO GUST AROUND 25 KNOTS ON OUR OCEAN WATERS TODAY AND WAVES SHOULD BE AROUND 5 FEET. AS A RESULT, A SMALL CRAFT ADVISORY WILL REMAIN IN PLACE. GUSTS SHOULD BE A LITTLE LOWER ON DELAWARE BAY THAN ON THE OCEAN, SO AN ADVISORY IS NOT IS EFFECT THERE. WHILE THE WIND SPEEDS ARE FORECAST TO DIMINISH TONIGHT, WAVES ON OUR OCEAN WATERS WILL LIKELY REMAIN IN THE NEIGHBORHOOD OF 5 FEET. THE SMALL CRAFT ADVISORY FOR OUR OCEAN WATERS HAS BEEN EXTENDED INTO FRIDAY. STRONG TO SEVERE THUNDERSTORMS IN ADVANCE OF A COLD FRONT APPROACHING FROM THE NORTHWEST WILL LIKELY IMPACT THE COASTAL WATERS OF NEW JERSEY AND DELAWARE THIS EVENING AND SPECIAL MARINE WARNINGS ARE POSSIBLE. OUTLOOK... FRIDAY...A FRONTAL BOUNDARY SHOULD BE DRAPED NEAR THE COAST IN A NEARLY STATIONARY FASHION. THIS COULD HELP FOCUS SOME CONVECTION, OTHERWISE A SOUTHEASTERLY WIND IS EXPECTED. THE FLOW SHOULD BE ON THE LIGHTER SIDE, HOWEVER INCOMING SWELLS FROM THE HURRICANE SHOULD HELP KEEP THE SEAS TO NEAR 5 FEET THUS A CONTINUATION OF THE SMALL CRAFT ADVISORY THROUGH 22Z. SATURDAY AND SUNDAY...THERE IS AN INCREASING POTENTIALLY FOR SERIOUS IMPACTS ACROSS THE WATERS FROM HURRICANE IRENE AS IT TRACKS NORTHWARD. THERE STILL REMAINS UNCERTAINTY ON THE EXACT TRACK OF THIS HURRICANE, WHICH WILL ULTIMATELY GOVERN THE WINDS ACROSS THE AREA. HOWEVER, SIGNIFICANT WINDS AND SEAS ARE EXPECTED BASED ON A VARIETY OF GUIDANCE TRACKS. THE INCREASING SWELLS ALONG WITH THE OVERALL INCREASING SEAS WILL TEND TO TURN CONDITIONS ON THE WATERS ROUGH TO EXTREMELY DANGEROUS. WE WILL HAVE TO PARTICULARLY WATCH DELAWARE BAY DUE TO POSSIBLE FUNNELING UP OF A SOUTHEAST WIND FOR A TIME PRECEDING THE HURRICANE. IN THE EVENT WATCHES OR WARNINGS ARE ISSUED FROM THE NATIONAL HURRICANE CENTER /NHC/, WE WOULD MORE THAN LIKELY DROP ANY OTHER MARINE HEADLINES THAT ARE UP AS THE EVENT DRAWS CLOSER AND THE EXACT TRACK BECOMES MORE CERTAIN. WE GENERALLY ARE USING A WIND GUST TOOL WITH NO MIXING AS IT WAS GIVING US RATHER RAMPED UP GUSTS, THEREFORE GENERALLY CAPPING THE GUSTS AT ABOUT 90 KNOTS AT THIS POINT. ALL INTERESTS SHOULD PAY VERY CLOSE ATTENTION TO THE FORECASTS THROUGH THE WEEKEND. THE CONDITIONS ACCOMPANYING THE HURRICANE WILL MORE THAN LIKELY LEAD TO THE FIRST HIGH RISK OF RIP CURRENTS THIS WEEKEND. THE HURRICANE IS FORECAST TO BE LIFTING WELL TO OUR NORTH LATER SUNDAY, THEREFORE IMPROVEMENTS WILL BEGIN TO TAKE PLACE. MONDAY...IRENE WILL BE OUT OF THE AREA THEREFORE ANY LINGERING GUSTY NORTHWESTERLY WINDS ARE ANTICIPATED TO LESSEN THROUGH THE DAY. && .HYDROLOGY... FOR LATER FRIDAY AND SATURDAY, PW VALUES START TO SURGE NORTHWARD WITH THE FLOW TURNING ONSHORE. THIS COULD BE LOCALLY ENHANCED ESPECIALLY IF A COASTAL FRONT IS IN PLACE OWING TO LOW- LEVEL CONVERGENCE AND LIFT. THE TIME FRAME TO KEY IN ON STILL APPEARS TO BE SATURDAY NIGHT THROUGH ABOUT MIDDAY SUNDAY AS HURRICANE IRENE MOVES UP THE COAST. WHILE THE TRACK WILL DETERMINE HOW MUCH RAIN FALLS ACROSS THE REGION AND WHERE THE MAIN AXIS IS, PLENTY OF HIGH MOISTURE CONTENT AIR IS FORECAST TO SURGE UP THE COAST. THIS IS SEEN IN THE PW VALUES FORECAST WHICH REACHES 2.0 TO 2.5 INCHES THROUGH SATURDAY. SOME MODEL GUIDANCE INDICATES THAT THESE VALUES SURGE TO A LITTLE OVER 3.0 INCHES ACROSS THE EASTERN PART OF THE CWA IF THE CENTER OF THE STORM IS RIGHT AT THE COAST. THE COMBINATION OF RATHER DEEP, HIGH MOISTURE CONTENT AIR AND LARGE SCALE LIFT FROM THE HURRICANE AND THE POTENTIAL DEVELOPMENT OF AN UPPER-LEVEL JET SEGMENT ACROSS NEW ENGLAND, WOULD LEAD TO EXCESSIVE RAINFALL RATES AND TOTALS. THIS WOULD BE ENHANCED EVEN FURTHER WITHIN CONVECTIVE BANDS. AS OF NOW, SEVERAL INCHES OF RAIN IS ANTICIPATED FOR AT LEAST A PORTION OF THE REGION. HOWEVER IF THE HURRICANE TRACKS FAR ENOUGH OFF OF OUR COAST, THE GRADIENT IN THE RAIN SHIELD MAY BE RATHER TIGHT FROM WEST TO EAST ESPECIALLY IF ENOUGH SUBSIDENCE OCCURS TO THE WEST OF THE TRACK. A CLOSER TO LAND TRACK WOULD SHIFT THE HEAVY RAIN AXIS WESTWARD. THIS NEEDS TO BE MONITORED VERY CLOSELY ESPECIALLY SINCE MOST OF THE AREA HAS BEEN RATHER WET THIS MONTH. WE WILL CONTINUE TO MENTION THIS IN THE HAZARDOUS WEATHER OUTLOOK AND CARRY A HEAVY RAIN MENTION IN THE FORECAST. && .RIP CURRENTS...
