NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Jul 6, 3:58 AM EST, 1 hour 27 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 458 AM EDT SUN JUL 6 2008 .SYNOPSIS... A WEAK FRONTAL BOUNNDARY ACROSS THE REGION WILL TEND TO DISSIPATE OVER THE NEXT COUPLE OF DAYS AS THE BERMUDA HIGH BECOMES RE- ESTABLISHED OVER THE MID-ATLANTIC REGION. A COLD FRONT WILL CROSS THE AREA AROUND MID-WEEK...FOLLOWED BY HIGH PRESSURE ON THURSDAY AND FRIDAY. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... THE PREVIOUS EVE TSTMS HAVE DIED OFF OVERNIGHT...ALTHO THERE IS SOME SCT CNVTN EARLY THIS MRNG OVER PARTS OF DELMARVA..JUST TO THE SOUTH OF OUR FCST AREA. THE ATMOS REMAINS MRGNLY UNSTABLE OVER THIS AREA SO WE ARE KEEPING A CHC OF SHRA IN THE MRNG FCST. BETTER CHC FOR SHRA/TSRA WILL BE THIS AFTN WITH DAYTIME HTG AND ABUNDANT LOW LVL MSTR RESULTING IN MORE INSTBY. ALSO...THE UPPER LOW CLOSING OFF OVER THE OH VLY WILL PROVIDE MORE SLY FLOW AND INCREASING MSTR FOR TODAY. THUS WE ARE EXPECTING MORE WIDESPRD TSTM ACTVTY THAN YDA AND THE MOIST ENV WILL ALLOW FOR LOCALLY HEAVY DOWNPOURS. WE DO NOT EXPECT ANY SGFNT FLOODING AS OVERALL CONDS ARE RATHER DRY...HWVR IF MULTIPLE STORMS TRAIN ACROSS A PARTICULAR AREA THERE COULD BE SOME PROBLEMS SO THIS BEARS WATCHING. && .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/... THE UPPER TROF REMAINS TO OUR WEST DURING THIS PERIOD AND THE AIRMASS WILL REMAIN QUITE MOIST AND SMWHT UNSTABLE. SHRA/TSTM ACTVTY FROM SUN WILL LIKELY PERSIST INTO THE EVE BUT GRADLY WEAKEN OVERNIGHT. THE WEAK Q-STNRY FNTL BNDRY ACROSS THE MID-ATLANTIC REGION IS FCST TO MOVE N AND/OR DISSIPATE BY MONDAY SO THERE MAY BE LESS OF A LOW- LVL FOCUSING MECH FOR CNVTN. STILL...THE AIRMASS AND OVERALL SYNOP PATN SHOULD SUPPORT SCT AFTN/EVE TSTMS. && .LONG TERM /MONDAY NIGHT THROUGH SATURDAY/... THE UPPER TROF IS FCST TO MOVE EWD OFF THE COAST AND WEAKEN ON TUE WITH THE FLOW ALOFT BECOMING MORE ZONAL ACROSS THE MID- ATLANTIC REGION. WITH THE UPPER PATN LESS FVRBL FOR CNVTN BUT THE SAME AIRMASS IN PLACE WE HAVE KEPT BASICALLY A MINIMAL CHC FOR AFTN/EVE TSTMS ACROSS ROUGHLY THE NW HALF OF THE FCST AREA. DAYTIME MAX TEMPS SHOULD SHOW A GRADUAL WARMING TREND MON AND TUE AS SMWHT WARMER AIR AT 850MB MOVES IN FROM THE WEST. FOR WED...AN UPPER TROF AND ASSOCD SFC CDFNT ARE FCST TO APPROACH FROM THE NW. THE CDFNT IS EXPECTED TO CROSS THE AREA WED EVE BUT SHOULD BE PRECEDED BY AFTN TSTMS...ALSO AIDED BY LEE TROF FCST OVER ERN PA. DYNAMICS MAY BE SUFF TO SUPPORT SOME SVR TSTMS AT THAT TIME. AFTER THE FRONTAL PASSAGE THE REMAINDER OF THE WEEK LOOKS MOSTLY DRY ALTHO WITH CONTD WARM TEMPS. && .AVIATION /08Z SUNDAY THROUGH THURSDAY/... .AVIATION... NEARLY STATIONARY FRONTAL ZONE OVER OUR FORECAST AREA WILL CONTINUE TO BE A FOCUS FOR CONVECTIVE ACTIVITY FOR THE NEXT 48 HOURS. SOME DRIER AIR TO OUR NORTH IS TRYING TO PUSH SOUTH BUT HAVING A DIFFICULT TIME DOING SO. WITH VERY LIGHT WINDS, ONLY SOME MID AND HIGH CLOUDS, AND PLENTY OF LOW LEVEL MOISTURE, FOG AND HAZE WILL PREVAIL THIS MORNING. CONDITIONS ARE CURRENTLY MVFR/IFR WITH A FEW AREAS DOWN TO LIFR. THIS WILL PERSIST UNTIL MID OR LATE MORNING WHEN CONDITIONS ARE EXPECTED TO IMPROVE TO VFR/MVFR. NOT MUCH IN THE WAY OF LOW LEVEL FLOW, SO VSBY IN MANY AREAS MAY REMAIN MVFR IN HAZE. DIFFICULT TO PINPOINT WHERE CONVECTION WILL FIRE UP AND LIKE YESTERDAY, STORMS WILL MOVE QUITE SLOWLY. EXPECT MOST CONVECTIVE ACTIVITY TO OCCUR IN THE AFTERNOON AND EVENING, WITH ONLY AN ISOLATED SHOWER OR TWO AT OTHER TIMES. ONCE THE CONVECTION TAPERS OFF LATER THIS EVENING, WELL START THE CYCLE ALL OVER AGAIN. OUTLOOK... THE FRONTAL ZONE WILL GRADUALLY WEAKEN AS A LARGE BERMUDA HIGH PRESSURE SYSTEM TAKES OVER THE CIRCULATION. THIS WILL BRING AN INCREASINGLY WARM AND HUMID FLOW TO OUR AREA AND CONTINUE THE THREAT OF SHOWERS AND THUNDERSTORMS THROUGH MIDWEEK. A COLD FRONT APPROACHING FROM THE NORTHWEST MAY WORK ITS WAY INTO THE FORECAST AREA WEDNESDAY NIGHT. && .MARINE... THE QUASI-STATIONARY FRONT OVER OF NEAR OUR WATERS IS FORECAST TO WEAKEN GRADUALLY OR LIFT NORTH AS A BERMUDA HIGH TO THE SOUTHEAST AND ASSOCIATED MID LEVEL RIDGE GRADUALLY BUILD. WE THEREFORE ARE MAINTAINING CONTINUITY AND FORECASTING A SOUTHERLY FLOW TO BE INCREASINGLY DOMINANT OVER ALL THE WATERS WITH TIME. EVENTUALLY, WHAT IS LEFT OF THE MID LEVEL LOW TO THE WEST AND AN ASSOCIATED COLD FRONT SHOULD MOVE ACROSS OUR AREA AND CAUSE WINDS TO SHIFT TO THE WEST. THIS PROBABLY WILL HAPPEN LATE IN THE FORECAST PERIOD, EITHER WEDNESDAY NIGHT OR THURSDAY. WINDS THROUGH THE FORECAST ARE PROGGED TO BE LIGHT TO MODERATE AND SEAS ARE CAPPED BELOW THE ADVISORY CRITERIA. SCATTERED SHOWERS AND TSTMS REMAIN IN THE FORECAST GIVEN THE MID LEVEL LOW TO THE WEST AND THE WARM AND HUMID AIR MASS. BECAUSE OF THE RISING DEW POINTS AND THE RELATIVELY COOL WATER TEMPERATURES, SOME FOG MAY OCCUR, ESPECIALLY IN THE OVERNIGHT AND MORNING PERIODS. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...NONE.
