AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 841 PM EDT MON SEP 10 2007 .SYNOPSIS... THE REMNANTS OF GABRIELLE WERE WELL EAST OF DELMARVA AND MOVING AWAY FROM THE REGION THIS EVENING. MEANWHILE, A MEANDERING FRONTAL BOUNDARY GENERALLY BISECTED THE FORECAST AREA NORTHEAST TO SOUTHWEST. LIGHT WINDS, NORTH BEHIND THE FRONT AND SOUTH TO SOUTHEAST TO THE EAST OF THE FRONT, HELPED DEFINE THE BOUNDARYS ZONE. A WEAK AREA OF LOW PRESSURE IS EXPECTED TO MOVE ALONG THE FRONT, CROSSING THE REGION EARLY TUESDAY MORNING. A COLD FRONT IS FORECAST TO CROSS THE REGION FROM THE NORTHWEST LATE TUESDAY AFTERNOON OR EARLY TUESDAY NIGHT. HIGH PRESSURE FROM CANADA WILL BUILD IN BEHIND THE FRONT FOR WEDNESDAY AND THURSDAY. ANOTHER COLD FRONT IS ANTICIPATED FOR SATURDAY. && .NEAR TERM /THROUGH TUESDAY/... THE MEANDERING FRONTAL BOUNDARY ALLOWED SOME LIGHT NORTHERLY WINDS TO DEVELOP IN EASTERN PENNSYLVANIA, NORTHERN DELAWARE, AND NORTHEASTERN MARYLAND, WHILE WEAK ONSHORE WINDS REMAINED OVER EASTERN NEW JERSEY WITH A FRONTAL BOUNDARY IN BETWEEN. THIS ALLOWED SOME WEAK BOUNDARY LAYER CONVERGENCE AND ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS FORMED THIS AFTERNOON, BUT THESE DIMINISHED WITH THE CESSATION OF DIURNAL HEATING. INFRARED SATELLITE IMAGERY SHOWED A BREAK BETWEEN THE HIGH CLOUDS ASSOCIATED WITH THE AFTERNOON CONVECTION AND THAT WHICH WAS UPSTREAM, BUT THE UPSTREAM CLOUDS WILL BE MOVING OVERHEAD SHORTLY SO MOSTLY CLOUDY TERMINOLOGY WILL BE USED FOR TONIGHT. LATER TONIGHT, A WEAK AREA OF LOW PRESSURE WILL MOVE NORTHEAST ALONG THE FRONT, CROSSING THE AREA NEAR PHILADELPHIA EARLY TUESDAY MORNING. SATELLITE SUPPORTS A WET SOLUTION WITH CLOUDS ENHANCING ON A BAROCLINIC ZONE IN KENTUCKY. MODELS BRING THIS MOISTURE NORTHEAST ACROSS THE AREA AFTER MIDNIGHT. SINCE RAIN IS NOT YET WIDESPREAD IN KENTUCKY, IT WAS NOT DESIRED TO GO WITH THE 100 PROBABILITIES SOME OF THE MET MOS GUIDANCE INDICATED, HOWEVER, IT DOES LOOK LIKE A HIGH ENOUGH PROBABILITY FOR LIKELY PROBABILITIES FOR MUCH OF THE AREA AND A CORE OF 80/CATEGORICAL POPS FOR SOUTHEAST PENNSYLVANIA NORTHEASTWARD INTO CENTRAL NEW JERSEY. THE ONLY AREA WHERE POPS ARE 50 OR LESS IS SOUTHERN DELAWARE, SINCE THIS AREA IS JUST TO THE SOUTH OF WHERE THE LIFT IS LOCATED. BY AFTERNOON, THIS SHORT WAVE/LOW MOVES OFF TO THE EAST AND A COLD FRONT APPROACHES FROM THE NORTHWEST. SOME INSTABILITY REMAINS AND THE FRONT COULD KICK OFF ANOTHER ROUND OF SHOWERS OR THUNDERSTORMS, BUT THE PRECIPITATION, IF IT FORMS, SHOULD NOT BE AS WIDESPREAD AS WHAT IS ANTICIPATED EARLIER IN THE MORNING. WITH QUITE A BIT OF CLOUDS AROUND, TEMPERATURES TUESDAY SHOULD NOT BE AS WARM AS MONDAY, BUT THE HUMIDITY WILL STILL BE RATHER ELEVATED. EVEN SO, THERE MAY BE SOME BREAKS OF SUNSHINE IN THE AFTERNOON, AND AFTER RELATIVELY HIGH MINIMUMS TONIGHT, THIS SHOULD BE ENOUGH FOR THE AFTERNOON HIGHS TO REACH THE LOW OR MID 80S SOUTH AND MID TO UPPER 70S NORTH. && .SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY/... SOME SHOWERS OR TSTMS COULD STILL BE AROUND TUESDAY EVENING BEFORE MUCH DRIER AIR /MUCH LOWER HUMIDITY/ ARRIVES LATER TUESDAY NIGHT. ON WEDNESDAY, HIGH PRESSURE WILL PROVIDE SOME BEAUTIFUL WEATHER WITH LOW HUMIDITY, AND COOLER TEMPERATURES. && .LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/... HIGH PRESSURE AND FAIR WEATHER ARE EXPECTED FOR THURSDAY AND FRIDAY. ANOTHER COLD FRONT IS ANTICIPATED FOR SATURDAY WITH ANOTHER POSSIBILITY OF SHOWERS AND TSTMS. EVEN COOLER WEATHER IS EXPECTED SUNDAY AS WE CONTINUE TO STAIR STEP OUR WAY TOWARD COOLER AUTUMNAL TEMPS. && .AVIATION /01Z TUESDAY THROUGH SATURDAY/... ALTHOUGH THE REGION CONTINUES TO EXPERIENCE MAINLY BROKEN CONDITIONS, ALL THE TAFS ARE RUNNING VFR. A WEAK WAVE OF LOW PRESSURE WILL MOVE NORTHEAST UP THE COLD FRONT THAT IS ACROSS THE REGION THIS AFTERNOON. THE VFR CONDITIONS WE ARE CURRENTLY EXPERIENCING WILL TRANSITION INTO MVFR THIS EVENING AND COULD VERY WELL CYCLE DOWN INTO THE IFR RANGE OVERNIGHT. THE WAVE WILL MAKE ITS WAY OUT OF HERE TOMORROW MORNING. ANOTHER COLD FRONT, RIGHT ON THE HEELS OF THE FIRST ONE, WILL CROSS THE REGION LATE TOMORROW. IMPROVEMENT IS EXPECTED BY MIDDAY TOMORROW AS THE WAVE MOVES OFFSHORE. MORE RESTRICTIONS TO CEILINGS AND VISIBILITIES CAN BE EXPECTED WITH THE SECOND FRONT LATER IN THE DAY ALTHOUGH THE PRECIPITATION LOOKS MORE CONVECTIVE AND SPOTTY RATHER THAN THE OVERRUNNING TYPE. HIGH PRESSURE WILL BRING FAIR WEATHER INTO THE REGION WEDNESDAY THROUGH FRIDAY. ANOTHER COLD FRONT IS EXPECTED ON SATURDAY. && .MARINE... THE NAM INDICATES AN EASTERLY COMPONENT TO THE FAIRLY LIGHT WINDS TONIGHT OVER THE NRN WATERS, AND IT INDICATES FAIRLY LIGHT SRLY WINDS ELSEWHERE. THIS VERIFIES WELL AGAINST THE 22Z OBS AND HAS BEEN FOLLOWED. SWELLS FROM GABRIELLE HAVE CAUSED SEAS TO REACH 5 FT AT 44025, WHILE SEAS AT 44009 ARE AROUND 3 FT. BECAUSE OF FEEDBACK FROM OUR MARINE COMMUNITY, WE WILL AVOID ISSUING A SCA FOR SWELLS OF AROUND 5 FT, BUT WE WILL REVISIT THAT DECISION IF THE SWELLS CONTINUE TO BUILD. SW WINDS WILL PICK UP AHEAD OF A SECONDARY COLD FRONT TOMORROW. THIS FRONT IS EXPECTED TO PASS OFF THE COAST TOMORROW NIGHT. ALTHOUGH WINDS WILL INCREASE TOMORROW (SEAS WILL FOLLOW), SCA CONDITIONS ARE NOT EXPECTED. THERE IS A BETTER CHANCE OF 25 KT AND 5 FOOT SEAS IN THE POST FRONTAL ENVIRONMENT TUESDAY NIGHT INTO WEDNESDAY. ANY INCREASE WILL BE SHORT LIVED THOUGH AS HIGH PRESSURE IS EXPECTED TO BUILD ACROSS AREA WATERS LATER WEDNESDAY INTO THURSDAY. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...NONE. NJ...NONE. DE...NONE.
