AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 408 PM EDT WED JUN 3 2009 .SYNOPSIS... A FRONTAL SYSTEM WILL CONTINUE TO MOVE SLOWLY THROUGH OUR AREA BEFORE SETTLING TO OUR SOUTH TONIGHT. A WEAK AREA OF HIGHER PRESSURE WILL TRY TO BUILD IN THURSDAY. A WAVE OF LOW PRESSURE WILL MOVE ALONG THE STALLED BOUNDARY AND MOVE UP THE MIDDLE ATLANTIC COAST FRIDAY. THE SYSTEM MOVES OFFSHORE LATE FRIDAY MAKING WAY FOR A RELATIVELY DRY WEEKEND. UNSETTLED WEATHER WILL REMAIN THROUGH THE MUCH OF NEXT WEEK AS ANOTHER FRONT IS EXPECTED TO STALL LATE IN THE WEEKEND. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... SEVERE THUNDERSTORM WATCH 325 REMAINS IN EFFECT THROUGH 8PM FOR PARTS OF OUR SOUTHERN AREAS AS THUNDERSTORMS DEVELOP AND MOVE ACROSS THE REGION. RAIN TO THE NORTH, ASSOCIATED WITH A SLOWLY SAGGING FRONTAL BOUNDARY, HAS HELPED TO STABILIZE THE AIR AS WINDS SHIFT FROM A SOUTHERLY DIRECTION TO MORE OF A NORTHERLY DIRECTION THIS AFTERNOON. THE GREATEST INSTABILITY THIS AFTERNOON REMAINS ACROSS THE DELMARVA AND THIS IS WHERE THE GREATEST THREAT FOR SEVER WEATHER WILL BE. DANGEROUS LIGHTENING, HEAVY RAIN, DAMAGING WINDS AND LARGE HAIL COULD FALL WITH ANY THUNDERSTORMS THAT DEVELOP WITHIN THIS REGION THROUGH THIS EVENING. THE CHANCE FOR THUNDERSTORMS SHOULD DECREASE AS WE LOSE SURFACE HEATING AND THE FRONT MOVES THROUGH THE REST OF THE AREA. PRECIPITABLE WATERS REMAIN QUITE HIGH AND WE HAVE THEREFORE LEFT IN THE MENTION FOR MODERATE RAIN/SHOWERS THROUGH THE OVERNIGHT PERIOD AND INTO THURSDAY. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/... ONCE THE FRONT IS SETTLED TO OUR SOUTH, A WEAK AREA OF HIGH PRESSURE WILL ATTEMPT TO MOVE ACROSS THE AREA. UNFORTUNATELY, THIS WILL NOT KEEP THE REGION DRY THROUGHOUT. OVERRUNNING WILL LIKELY KEEP SOME SHOWERS AROUND AND WAVE MOVING ALONG THE STALLED BOUNDARY WILL HELP CONTRIBUTE TO SOME PRECIPITATION AS WELL. ONCE AGAIN THE GREATEST INSTABILITY LIES IN THE DELMARVA AND WE HAVE SHAVED BACK ON THUNDER IN THE NORTHERN AREAS FOR THURSDAY. THIS WAVE OF LOW PRESSURE WILL MOVE UP THE MIDDLE ATLANTIC COAST FRIDAY BEFORE MOVING OFFSHORE FRIDAY NIGHT. ALL IN ALL, THE UNSETTLED WEATHER WILL CONTINUE THROUGH THE END OF THE WEEK. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... HIGH PRESSURE IS EXPECTED TO BUILD IN FOR SATURDAY WITH IMPROVING CONDITIONS FOR THE WEEKEND. A COLD FRONT WILL APPROACH LATE SATURDAY INTO SUNDAY AND COULD POSSIBLY STALL ACROSS THE REGION FOR FOR MONDAY. EVEN WITH THIS SYSTEM EXPECTED TO MOVE ACROSS THIS WEEKEND IT LOOKS RELATIVELY DRY AND THEREFORE THE WEEKEND LOOKS TO BE THE BEST DAYS WITHIN THE FORECAST. ANOTHER FRONTAL SYSTEM IS EXPECTED TO MOVE INTO THE AREA ON TUESDAY WITH THE ASSOCIATED COLD FRONT MOVING THROUGH EARLY WEDNESDAY. THIS WOULD KEEP US IN AN ACTIVE WEATHER PATTERN AND WE HAVE DECIDED TO LEAVE THE CHANCE FOR SHOWERS AND THUNDERSTORMS THROUGH THE PERIOD. WITH INCREASED UNCERTAINTY THROUGH THE PERIOD AND LACK OF CONSENSUS AMONG MODELS, WE HAVE DECIDED TO STICK WITH HPC GUIDANCE THROUGHOUT THE EXTENDED. && .AVIATION /20Z WEDNESDAY THROUGH MONDAY/... THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY AND SURROUNDING AREAS. SEVERE THUNDERSTORM WATCH UNTIL 8 PM EDT FOR TAF SITES SOUTH OF PHL. TSTMS WILL BE SCATTERED OVER THE DELAWARE VALLEY NEXT COUPLE HOURS BUT WAITING FOR A SQUALL LINE TO FORM AROUND 2030Z TO THE WEST AND MOVE INTO TAF SITES BETWEEN 21-2130Z. INSERTED BRIEF GUSTY WIND PERIOD WITH HIGHEST GUSTS OVER SOUTHERN SITES. OTHERWISE...REMAINING AT LEAST HIGH MVFR TO VFR EXCEPT IN HEAVIER SHOWERS. WEST-EAST SURFACE FRONT WITH DEVELOP A LOW ON IT PLAYING HAVOC WITH WIND DIRECTION. UNDER 10 KTS SO LIKELY TO SWING AROUND DEPENDING UPON AMOUNT OF SUN/CLDS TO UNEVENLY DISTRIBUTE HEATING. THE FRONTAL BOUNDARY IS GOING TO REMAIN WITH US INTO THE WEEKEND WITH MOST AREAS NORTH OF THE WARM FRONT. THUS...CEILINGS WILL BE MVFR TO IFR FROM LATE THURSDAY INTO FRIDAY AS THE EAST TO NORTHEAST WINDS PREVAIL. OUTLOOK... IMPROVEMENT FOR SATURDAY AND SUNDAY WITH HIGH PRESSURE BUILDING OVER THE TRACON AND GOOD VFR RETURNING. && .MARINE... SEVERE THUNDERSTORM WATCH IN EFFECT FOR THE DELAWARE BAY UNTIL 8 PM EDT. ALTHOUGH FOR DELAWARE BAY, SOME STRONG STORMS ARE ALSO POSSIBLE OVER THE SOUTHERN COASTAL WATERS OF NJ AND DELAWARE. WEAK PRESSURE PATTERN OVER THE REGION AS WEST TO EAST FRONT ACTING AS BOUNDARY BETWEEN STABLE RAINS NORTH AND POSSIBLY STRONG TSTMS SOUTH OF IT. THE THUNDERSTORMS ON TUESDAY WERE ACCOMPANIED BY VIVID LIGHTNING. BETWEEN THE HOURS OF 5 AND 6 PM, THERE WERE 880 LIGHTNING STRIKES WHEN THE STORMS MOVED THROUGH. DONT SEE ANY DIFFERENCE TODAY SO BE CAUTIOUS ON THE WATER. SEAS ARE 2 TO 3 FEET ON THE OPEN OCEAN AND 1 TO 2 ON THE DELAWARE BAY. WEAK LOW FORMS ON THE FRONT THIS EVENING AND STRENGTHENS A LITTLE AS IT MOVES AWAY FROM THE DE COAST TONIGHT. SOME GUSTY EAST WINDS MAY BRING SEAS UP A COUPLE FEET BUT AT THIS TIME NOT RAISING SMALL CRAFT ADVISORIES. MUCH BIGGER LOW PRESSURE IS FORMING OVER GULF COAST STATES ON THURSDAY AND MOVES NORTHEAST WITH A MUCH TIGHTER GRADIENT OR ASSOCIATED WIND FLOW. THE ELONGATE LOW PRESSURE REACHES THE COASTAL WATERS FRIDAY AFTERNOON AND EXTENDS TO THE FLORIDA PANHANDLE. THE ENTIRE SYSTEM MOVES OFFSHORE BY SATURDAY AFTERNOON AS HIGH PRESSURE BUILDS OVER THE COASTAL WATERS OVER THE WEEKEND. PLENTY OF ACTION AROUND US BUT THE PATTERN REMAINS RATHER TRANQUIL FOR US INTO MONDAY AND TUESDAY. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...NONE. NJ...NONE. DE...NONE. MD...NONE.
