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 14, 3:15 PM EST, 3 hours 25 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 415 PM EDT THU AUG 14 2008 .SYNOPSIS... OUR AREA WILL REMAIN UNDER THE INFLUENCE OF AN UPPER LEVEL LOW PRESSURE AREA WELL INTO THE WEEKEND, AS SEVERAL DISTURBANCES CROSS THE REGION. A COLD FRONT WILL MOVE SLOWLY THROUGH THE AREA FRIDAY AND FRIDAY NIGHT. AS THE UPPER LEVEL LOW MOVES EAST OF THE AREA SUNDAY, A SURFACE HIGH PRESSURE SYSTEM WILL BUILD ACROSS THE REGION AND CONTINUE INTO EARLY NEXT WEEK. A COLD FRONT IS EXPECTED TO AFFECT THE AREA TUESDAY INTO WEDNESDAY, BUT HIGH PRESSURE IS EXPECTED TO FOLLOW FOR THE END OF NEXT WEEK. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... AN APPROACHING SHORT WAVE ALOFT AND TERRAIN EFFECTS HAVE COMBINED TO INITIATE SCATTERED CONVECTION OVER OUR NORTHWESTERN ZONES AT MID AFTERNOON, AS WELL AS TO AREAS JUST TO OUR WEST AND SOUTHWEST. THE MOST NUMEROUS COVERAGE THIS EVENING IS EXPECTED TO BE OVER OUR NORTHERN ZONES WHERE THE BEST LIFT AND FORCING IS LOCATED. DIURNAL EFFECTS ARE AIDING THE MODERATE INSTABILITY LATE THIS AFTERNOON AND SHOULD SUBSIDE LATER THIS EVENING, BUT AS A SURFACE COLD FRONT DRIFTS SOUTHEASTWARD INTO OUR AREA LATE TONIGHT AND EARLY FRIDAY, ADDITIONAL CONVECTION IS EXPECTED. AGAIN, THE HIGHER LIKELY PROBABILITIES WERE LEFT FOR THE NORTHERN AREAS, WITH HIGH CHANCE FURTHER SOUTH. ENHANCED WORDING WAS ADDED, ALTHOUGH REPORTS FROM MID AFTERNOON SO FAR HAVE NOT INDICATED MUCH IN THE WAY OF SEVERE WEATHER YET. WITH THE LOW FREEZING LEVEL, THE LARGEST OF ANY THREAT THIS EVENING APPEARS TO BE LARGE HAIL, BUT HEAVY RAIN COULD OCCUR IN A FEW PLACES. FLASH FLOOD GUIDANCE IS FAIRLY HIGH AT THIS TIME. WITH CONVECTION AND CLOUDS, RADIATION WILL NOT BE IDEAL TONIGHT. THE VARIOUS MOS GUIDANCE PRODUCTS WERE PRETTY CLOSE ON MINIMUM TEMPERATURES, IDENTICAL IN SOME CASES, SO THE GFS MOS WAS ACCEPTED AND USED. && .SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY/... WITH A SURFACE FRONT MOVING THROUGH THE AREA, COUPLED WITH THE UPPER TROUGH ROTATING THROUGH THE MID ATLANTIC REGION AND WITH GOOD INSTABILITY, NUMEROUS SHOWERS AND THUNDERSTORMS SHOULD RESULT, WITH SOME CONVECTION REACHING NEAR OR OVER SEVERE LEVELS. OUR AREA CONTINUES TO REMAIN UNDER THE CRITERIA FOR A SLIGHT RISK FOR SEVERE THUNDERSTORMS, BUT IT APPEARS TO BE CLOSE TO IT. THE RESPONSIBLE FORCING MECHANISMS APPEAR TO BE ON THEIR WAY OUT, WITH MORE STABLE AIR RESULTING, BY LATER FRIDAY NIGHT. FOR NOW, IT WAS DECIDED TO LEAVE PRECIPITATION OUT OF THE FORECAST FOR SATURDAY MORNING, BUT REINTRODUCE IT FOR SATURDAY AFTERNOON AS DIURNAL EFFECTS ACT ON THE RESIDUAL MOISTURE AND INSTABILITY ASSOCIATED WITH THE UPPER TROUGH AXIS RIGHT OVER THE AREA. MORE DIVERGENCE WAS NOTED IN MOS GUIDANCE SOLUTIONS FOR FRIDAY AND SATURDAY. WITH CLOUDS AND CONVECTION FRIDAY, AS WELL AS A SLIGHTLY COOLER WEST TO NORTHWEST FLOW SATURDAY, A BLEND OF MOS WAS USED. && .LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/... THE SHARP TROUGH AXIS IS MOVED OUT OF THE AREA SATURDAY NIGHT, BUT CYCLONIC FLOW ALOFT IS STILL RETAINED BY THE MODELS SUNDAY AND MONDAY. WITH A WEST TO NORTHWEST FLOW ALOFT, AND STABILITY LIKELY REMAINING MARGINAL, ISOLATED CONVECTION ESPECIALLY OVER TERRAIN AREAS CANNOT BE RULED OUT ENTIRELY SUNDAY AND MONDAY, BUT IT WAS LEFT OUT OF THE FORECAST FOR NOW. RISING HEIGHTS COULD LEAD TO SOME WARM ADVECTION TUESDAY, BUT THERE APPEARS TO BE SOME LOW LEVEL FORCING WHICH COULD INITIATE ADDITIONAL CONVECTION, ESPECIALLY LATER TUESDAY INTO WEDNESDAY AS ANOTHER FRONT MOVES THROUGH. FOR NOW, DRY WEATHER WAS FORECAST FOR THURSDAY WITH HIGH PRESSURE FOR NOW. HPC GUIDANCE TEMPERATURES WERE USED, AND THIS AGREED ACCEPTABLY WELL WITH EXTENDED GFS MOS GUIDANCE. && .AVIATION /20Z THURSDAY THROUGH TUESDAY/... ISSUED TAFS HAVE A LOWER CONFIDENCE THAN AVERAGE FORECAST FOR THIS TAF PERIOD BECAUSE OF SCATTERED TO WIDELY SCATTERED CONVECTION EXPECTED. WHILE IN GENERAL VFR CONDITIONS ARE SHOULD PREVAIL INTO THIS EVENING, IFR CONDITIONS MIGHT OCCUR DURING ANY THUNDERSTORMS. AT THE MOMENT BEST CONFIDENCE OF THIS AFFECTING ANY TERMINAL IS KABE, WE WOULD EXPECT THE LEAST AFFECT FROM THE TSRAS AT KACY AND KMIV. THUNDERSTORMS ARE DEVELOPING OVER THE HIGHER TERRAIN WHICH MEANS THROUGH THE AFTERNOON HOURS, THE HIGHEST CHANCES OF THEM AFFECTING TERMINAL LOCATIONS WOULD BE KABE AND KRDG IN THAT ORDER. TAFS HAVE BEEN AMENDED TO INCLUDE TSRAS AT KRDG AND WE JUST AMENDED THE TAFS AROUND THE LOCAL PHILLY AREA TO TIME THE ARRIVAL OF THE CONVECTION AT OR ABOUT 22Z. AN OUTFLOW BOUNDARY OR GUST FRONT FROM THE THUNDERSTORM NEAR LONG BEACH ISLAND NJ WILL BE FOLLOWED TO SEE IF IT WILL HAVE ENOUGH ENERGY TO POSSIBLY INDUCE TSRAS EARLIER AT THE OTHER TERMINAL LOCATIONS. OTHERWISE THROUGH THE AFTERNOON A BAY BREEZE WIND SHIFT WAS INCLUDED FOR KILG AND A SEA BREEZE WIND SHIFT FOR KACY. BEST CHANCES FOR ANY TSRA ACTIVITY TO REACH THE TERMINAL REGION WILL BE DURING THE EVENING HOURS AS AN UPPER AIR DISTURBANCE OVER WESTERN PENNSYLVANIA MOVES CLOSER TO THE REGION. BELIEVE AS THE NIGHT CONTINUES THE CHANCES OF A TSRA AFFECTING ANY OF THE TERMINALS WILL DECREASE. DEW POINTS IN GENERAL ARE HIGHER THAN A COUPLE OF DAYS AGO AND WE CONTINUED TO MENTION SOME LIGHT MVFR FOG AT MOST TERMINALS OVERNIGHT. IF A TERMINAL DOES HAVE A TSRA, THE CHANCES FOR IFR CONDITIONS DUE TO MORNING FOG WILL INCREASE. WE USED THE APPROXIMATE DISSIPATION TIME OF THE FOG THIS MORNING (12Z-13Z) TO BRING BACK VFR CONDITIONS. OUTLOOK... A MORE ORGANIZED AREA OF SHOWERS AND THUNDERSTORMS IS LIKELY LATER IN THE DAY FRIDAY INTO FRIDAY EVENING. THIS COULD BRING MORE WIDESPREAD IFR CONDITIONS AS IT MOVES THROUGH ALONG WITH STRONG GUSTY WINDS AND FREQUENT LIGHTNING. THEN GENERALLY VFR CONDITIONS (OUTSIDE OF POSSIBLY SOME EARLY MORNING FOG OR HAZE) IS EXPECTED TO PERSIST INTO MONDAY WITH THE NEXT CHANCE FOR PRECIPITATION INDUCED CIG AND VSBY RESTRICTIONS ON TUESDAY. && .MARINE... SCA CONDITIONS ARE NOT EXPECTED THROUGHOUT THE FORECAST PERIOD. A PAIR OF UPPER AIR DISTURBANCES IN THE GENERAL SW FLOW ALOFT WILL HELP TRIGGER SHOWERS AND THUNDERSTORMS INTO FRIDAY NIGHT. THE SOUTHERLY FLOW PRECEDING THE TWO IMPULSES WILL START TO INCREASE SEAS OVER THE OCEAN, BUT THE SWELLS ARE EXPECTED TO REMAIN BELOW SCA CRITERIA INTO FRIDAY. SEAS SHOULD THEN SUBSIDE TOWARD THE WEEKEND AS A WEAK OFFSHORE FLOW DEVELOPS. WEAK HIGH PRESSURE BUILDING INTO THE REGION ON THE WEEKEND SHOULD PROVIDE CHAMBER OF COMMERCE CONDITIONS WITH WINDS AND SEAS WELL BELOW SCA CRITERIA. THIS SHOULD CONTINUE INTO MONDAY. THE NEXT THREAT FOR POSSIBLY ORGANIZED PRECIPITATION AS WELL AS HIGHER WINDS AND SEAS WILL BE WITH THE NEXT APPROACHING COLD FRONT TUESDAY. FOR NOW OUTSIDE OF ANY TSTMS, WINDS AND SEAS ARE EXPECTED TO REMAIN BELOW SCA CRITERIA. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...NONE. NJ...NONE. DE...NONE. MD...NONE.
