NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Jun 16, 1:56 PM EST, 2 hours 26 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 256 PM EDT MON JUN 16 2008 .SYNOPSIS... A COLD FRONT WILL MOVE SOUTHEAST FROM THE GREAT LAKES REGION AND CROSS THE REGION TONIGHT. LOW PRESSURE IS FORECAST TO MEANDER OVER SOUTHERN QUEBEC AND NEW ENGLAND ON TUESDAY AND WEDNESDAY BEFORE LIFTING TO THE NORTH ON THURSDAY. HIGH PRESSURE SHOULD BUILD IN FROM THE WEST FOR FRIDAY AND THE COMING WEEKEND. && .NEAR TERM /THROUGH TONIGHT/... A SEVERE THUNDERSTORM WATCH REMAINS IN EFFECT FOR THE ENTIRE FORECAST AREA UNTIL 9 PM THIS EVENING. THUNDERSTORMS HAVE DEVELOPED OVER CENTRAL NEW YORK AND CENTRAL PENNSYLVANIA EARLY THIS AFTERNOON AND WILL MOVE INTO THE AREA OVER THE NEXT FEW HOURS. A FAIR AMOUNT IF INSTABILITY EXISTS AHEAD OF THE LINE OF STORMS WITH CAPE VALUES EXCEEDING 1000 J/KG AND LIS OF -5 OR MORE. MAIN THREAT WILL BE DAMAGING WINDS AND LARGE HAIL. THESE STORMS SHOULD MOVE THROUGH RATHER QUICKLY, FROM NORTHWEST TO SOUTHEAST, THIS EVENING AS A COLD FRONT APPROACHES FROM THE WEST. THE FRONT SHOULD CROSS THE REGION BY EARLY MORNING WITH MUCH COOLER TEMPERATURES AND A WEST TO NORTHWEST FLOW LINGERING IN ITS WAKE. && .SHORT TERM /TUESDAY THROUGH THURSDAY/... THE COLD FRONT WILL CLEAR THE REGION BY TUESDAY MORNING USHERING IN SOME COOLER TEMPERATURES. A NICE BIG UPPER LEVEL LOW WILL SWING DOWN FROM THE GREAT LAKES REGION AND INFLUENCE OUR WEATHER FOR A FEW DAYS WITH SEVERAL SHORTWAVES EXPECTED TO ROTATE AROUND THE LOW. WHEN COMBINE WITH DAYTIME HEATING, THIS WILL BRING SOME INSTABILITY SHOWERS TUESDAY AND WEDNESDAY. BEING THAT THIS IS THE METEOROLOGICAL SUMMER, THUNDER REMAINS A POSSIBILITY BUT CONFIDENCE IS TOO LOW AT THE MOMENT TO INCLUDE IT IN THIS FORECAST PACKAGE. THE 12Z GFS/12Z NAM/09Z SREF HAVE 850MB TEMPS STAYING BELOW +10C THROUGH THE END OF THE PERIOD WHILE THE 00Z ECMWF WAS A LITTLE BIT WARMER, AROUND +10C FOR THE PERIOD. TEMPS WILL REMAIN ON THE COOL SIDE WITH TEMPS REACHING UP NEAR 80, MAYBE SLIGHTLY HIGHER, FOR PHL AND SOUTH AND 70S NORTH AND WEST ON TUESDAY. TEMPS ON WEDNESDAY AND THURSDAY LOOK TO REMAIN IN THE 70S THROUGHOUT THE CWA. && .LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/... THE UPPER LEVEL LOW WILL SPIN OFF TO THE NORTH THURSDAY AFTERNOON OR EVENING. HOWEVER, AS THE LOW SPINS NORTHWARD A PIECE BREAKS OFF AND SPINS BACK TOWARD OUR REGION. THIS LOW, HOWEVER, DOES NOT HANG AROUND FOR LONG AND CLEARS OUT RELATIVELY QUICKLY. HIGH PRESSURE WILL BUILD IN FOR FRIDAY INTO THE WEEKEND, WHICH SHOULD KEEP THE AREA RELATIVELY DRY. THE NEXT SYSTEM WILL APPROACH FROM THE SOUTHWEST AND IS EXPECTED TO SKIRT THE SOUTHERN ZONES MONDAY INTO TUESDAY. && .AVIATION /19Z MONDAY THROUGH SATURDAY/... ALTHOUGH VFR CONDITIONS COVERED THE REGION AT 2 PM, TSTMS WERE FORMING UPSTREAM AND ARE HEADED TO THE SE AND E. ALL TAF SITES COULD BE AFFECTED BY THE TSTMS. ALSO, A SEVERE TSTM WATCH IS IN EFFECT UNTIL 9 PM. I AM NOT CERTAIN ALL SITES WILL SEE STRONG TSTMS, THEREFORE, I ONLY BROUGHT CIG/VSBY DOWN TO MVFR IN TSTMS, BUT SOME AREAS COULD SEE IFR/LIFR IN THE STORMS IF THE HEART OF THE STORM MOVES OVER AN AIRPORT. AFTER MIDNIGHT, CONDITIONS WILL AGAIN IMPROVE TO VFR. HOWEVER, SOME VSBY COULD DROP TO 3-5 MI IN EARLY MORNING HAZE OR LIGHT FOG SINCE THE DRIER WESTERLY FLOW IS NOT EXPECTED TO ARRIVE UNTIL AFTER SUNRISE. SUNSHINE COMBINED WITH A WESTERLY FLOW ALOFT WILL ALLOW FOR GUSTY WINDS TO DEVELOP WITH DAYTIME HEATING AND WINDS COULD GUST TO 20 KTS DURING TUESDAY. OUTLOOK...SCATTERED SHOWERS COULD DEVELOP EACH AFTERNOON, HOWEVER, MOST AREAS SHOULD SEE VFR CONDITIONS CONTINUE. ISOLATED TSTMS ARE ALSO POSSIBLE WED AND THU AFTN. && .MARINE... EXPECT AN EXTENDED PERIOD OF TRANQUIL CONDITIONS TO CONTINUE ON THE WATERS. A COLD FRONT MOVES THROUGH EARLY TUESDAY. THIS COLD FRONT WAS CAUSING TSTMS OVER NY/PA/MD THIS AFTN AND THESE STORMS SHOULD REACH THE COASTAL WATERS THROUGH EARLY TONIGHT AND THEN WEAKEN TO SHOWERS LATE TONIGHT. SOME TSTMS COULD BECOME SEVERE THIS EVENING. WEAK HIGH PRESSURE WILL BUILD IN FROM THE WEST THROUGH THE MIDDLE OF THE WEEK WHILE AN UPPER LOW ROTATES TO OUR NORTH. THIS LOW COULD ALLOW SOME UNSETTLED WEATHER EACH AFTERNOON, BUT WINDS AND SEAS SHOULD REMAIN BELOW SCA CRITERIA. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...NONE. NJ...NONE. DE...NONE. MD...NONE.
