NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Jun 14, 1:38 PM EST, 3 hours 52 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 238 PM EDT SAT JUN 14 2008 .SYNOPSIS... A COLD FRONT WILL DROP SOUTHEAST FROM THE GREAT LAKES AND MOVE THROUGH THE REGION LATE TONIGHT FOLLOWED BY WEAK HIGH PRESSURE SUNDAY. ANOTHER COLD FRONT WILL APPROACH FROM THE WEST MONDAY AND THEN MOVE THROUGH THE REGION EARLY TUESDAY. ON WEDNESDAY THROUGH FRIDAY, LOW PRESSURE WILL REMAIN OVER NORTHERN NEW ENGLAND WHILE HIGH PRESSURE REMAINS OVER THE MIDWEST. && .NEAR TERM /UNTIL EARLY SUNDAY MORNING/... A SURGE OF WARM HUMID AIR AHEAD OF A COLD FRONT MOVING IN FROM THE GREAT LAKES REGION WILL ALLOW SHOWERS AND TSTMS TO SPREAD IN FROM THE WEST THIS EVENING. THE SHOWERS AND TSTMS SHOULD CONTINUE TO DEVELOP THIS EVENING IN RESPONSE TO AN UNSTABLE AIRMASS IN PLACE COMBINED WITH DIFLUENCE ALOFT AND AN APPROACHING COLD FRONT. WINDS ALOFT ARE GENERALLY LIGHT, SO THE THREAT OF WIDESPREAD SEVERE IS UNLIKELY. HOWEVER, SOME TSTMS COULD HAVE STRONG GUSTY WINDS, AND TORRENTIAL DOWNPOURS AS WELL AS DANGEROUS LIGHTNING. THE COLD FRONT MOVES THROUGH FROM THE NORTHWEST EARLY SUNDAY MORNING. SCATTERED SHOWERS AND TSTMS REMAIN POSSIBLE UNTIL THE FRONT MOVES THROUGH, THEN DRY AIR SHOULD MOVE IN FROM THE WEST. THERE IS A POSSIBILITY OF SOME SHOWERS LINGERING INTO SUNDAY MORNING OVER THE SOUTHEAST ZONES, EVEN AFTER THE FRONT CROSSES. THIS IS DUE TO THE FACT THAT A SHORT WAVE ALOFT LINGERS BEHIND THE FRONT AND COULD SLOW THE PROGRESSION OF THE DRYING ON SUNDAY. && .SHORT TERM /SUNDAY MORNING THROUGH MONDAY NIGHT/... DURING SUNDAY MORNING, AND CERTAINLY BY AFTERNOON, THE DRY AIR COMES IN FROM THE NORTHWEST ALLOWING SKIES TO BECOME PARTLY SUNNY. TEMPERATURES WILL STILL BE WARM, AS THE 850 TEMPS WILL STILL BE AROUND PLUS 14, BUT HUMIDITY WILL BE LOWER THAN THIS AFTERNOON. SUNDAY NIGHT LOOKS DRY. SKIES SHOULD BE PARTLY CLOUDY AS WE CONTINUE TO HAVE SHORT WAVES MOVE THROUGH ALOFT. ON MONDAY, ANOTHER COLD FRONT WILL APPROACH FROM THE NORTHWEST. WARM AIR WILL REMAIN OVER THE REGION AS A SW FLOW AHEAD OF THE FRONT BRINGS IN SOME MORE MOISTURE FROM THE SOUTHWEST. INITIALLY, THIS WILL CAUSE AN INCREASE IN CLOUDS. BUT BY LATE AFTERNOON, THERE COULD BE ENOUGH INSTABILITY TO GENERATE SCATTERED SHOWERS OR TSTMS. I WENT A BIT BELOW MAV TEMPS FOR HIGHS, DUE TO UNCERTAINTY AS CLOUDS COULD LIMIT HOW WARM WE GET. MONDAY NIGHT AGAIN LOOKS WET WITH THE FRONT MOVING THROUGH FROM THE WEST AND A WEAK AREA OF LOW PRESSURE COULD BE ON THE FRONT. DEPENDING OF IF THE WEATHER INGREDIENTS COME TOGETHER LIKE THE GFS SHOWS, WE COULD HAVE SOME HEAVY RAIN WITH THE FRONT. AGAIN MAV TEMPS WERE GENERALLY USED. && .LONG TERM /TUESDAY THROUGH SATURDAY/... COOL CYCLONIC FLOW ALOFT WILL ALLOW FOR BELOW NORMAL TEMPERATURES OVER THE REGION. A COLD FRONT THAT MOVES THROUGH EARLY TUESDAY MORNING THEN LOW PRESSURE OVER NEW ENGLAND WILL KEEP A WEST TO NORTHWEST FLOW OVER THE REGION WEDNESDAY THROUGH FRIDAY. THE UPPER FLOW SHOULD WEAKEN ENOUGH ON SATURDAY TO ALLOW AN AREA OF HIGH PRESSURE TO FORM OVER THE APPLACHIANS. THE COOL CYCLONIC FLOW ALOFT WILL MEAN THAT SOME SHOWERS ARE POSSIBLE WEDNESDAY AND THURSDAY AFTERNOON IN RESPONSE TO DAYTIME HEATING AND INSTABILITY CAUSED BY THE CYCLONIC FLOW. THIS MIGHT EXTEND INTO FRIDAY, BUT FOR NOW POPS WILL BE KEPT AT 20 PERCENT. ON SATURDAY, HIGH PRESSURE SHOULD PROVIDE DRY WEATHER AND TEMPERATURES THAT ARE A BIT WARMER. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... IT IS VFR ACROSS THE TAF SITES THIS AFTERNOON AND IT LOOKS LIKE THE EARLIER HAZE/SMOKE HAS MIXED OUT IN MOST AREAS. SHOWERS AND THUNDERSTORMS HAVE DEVELOPED TO THE WEST, AND THESE SHOULD MOVE INTO OUR AREA THIS EVENING AND OVERNIGHT. I HAVE DECIDED TO USE THE VCSH AREA-WIDE OVERNIGHT AND TRY TO TIME TWO PERIODS WHEN THE CHANCES WILL BE GREATER IN TEMPO GROUPS. THERE IS LIMITED CONFIDENCE IN THE TIMING FOR THE TEMPO GROUPS HOWEVER. ONCE THE PERIOD OF SHOWERS END LATE TONIGHT, SOME LIGHT FOG IS EXPECTED, AND WAS RETAINED FROM THE PREVIOUS TAFS. VFR AND A DRYING NW WIND EXPECTED AFTER 14Z OR 15Z SUN. OUTLOOK...FINE WEATHER EXPECTED SUNDAY THROUGH MOST OF MONDAY. ANOTHER LOW PRESSURE SYSTEM AND FRONT WILL BRING LOWER CONDITIONS MONDAY NIGHT AND POSSIBLY INTO TUE MORNING. && .MARINE... CONDITIONS WILL REMAIN SUB-SCA OVER THE WATERS TONIGHT AND THE REST OF THE WEEKEND. WINDS WILL BE GUSTY AND SEAS CHOPPY LOCALLY IN ANY THUNDERSTORM WHICH MAY VISIT THE WATERS TONIGHT, BUT OVERALL CONDITIONS WILL NOT BE THAT BAD. SEAS WILL INCREASE LATER MONDAY INTO MONDAY NIGHT AS THE NEXT LOW AND FRONT APPROACH, BUT OUR PRESENT FORECAST KEEPS CONDITIONS SCA THEN TOO. A BETTER CHANCE FOR SCA CONDITIONS WILL ARRIVE TUE AS THE COOLER AND DRIER AIR ARRIVE. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...NONE. NJ...NONE. DE...NONE. MD...NONE. MARINE...NONE. && SYNOPSIS...STAUBER NEAR TERM...STAUBER SHORT TERM...STAUBER LONG TERM...STAUBER AVIATION...OHARA MARINE...OHARA
