NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Jun 30, 8:50 PM EST, 1 hour 10 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 950 PM EDT MON JUN 30 2008 .SYNOPSIS... A SECONDARY COLD FRONT OVER THE GREAT LAKES IS EXPECTED TO MOVE SOUTHEAST THROUGH THE REGION OVERNIGHT. THE UPPER AIR SYSTEM DRIVING THE COLD FRONT WILL MOVE THROUGH THE REGION ON TUESDAY NIGHT. A HIGH PRESSURE SYSTEM WILL THEN BRIEFLY BUILD OVER THE REGION ON WEDNESDAY AND EARLY THURSDAY BEFORE MOVING OFFSHORE. ANOTHER COLD FRONT IS FORECAST TO REACH THE GREAT LAKES ON THURSDAY AND MOVE SOUTHEAST AND THEN STALL OVER OR CLOSE TO THE REGION ON INDEPENDENCE DAY AND INTO THE HOLIDAY WEEKEND. && .NEAR TERM /THROUGH TONIGHT/... LIKE THE GFS INITIALIZATION SLIGHTLY BETTER THAN THE WRF-NMM AT 500MB HAS IT HAS MORE OF A TIGHTER CLOSED LOW LOOK TO IT. BOTH MODELS LOOKED OK AT 850MB AND WERE A TAD TOO COOL AT 925MB. THIS HAS NOT WORKED ITS WAY DOWN TO THE SURFACE AS TEMPS ARE RUNNING LOWER THAN EXPECTED TODAY. WE WILL TREND TOWARD THE GFS SOLUTION BECAUSE OF ITS BETTER HANDLING OF TUESDAYS POTENTIAL WX, IT HAD IT ALL ALONG. THE MAIN UPPER AIR TROF IS GOING TO REMAIN WEST OF OUR CWA THROUGH TONIGHT. EVEN THOUGH THE APPEARANCE CHANGES, THE FLOW BACKS MORE TO THE SOUTH, THE FCST HEIGHT FIELDS CHANGE LITTLE. THUS WHAT SHORT WAVES ARE FORECAST TO PASS THROUGH OUR CWA IN THE EARLY MORE ACTIVE PART OF THE NIGHT ARE IN OUR NW ZONES. THUS POPS HAVE A NW TO SE GRADIENT TO THEM FOR THE EVENING HOURS. UNLIKE YESTERDAY THE INITIAL FRONT HAS TAKEN THE DEEP MOISTURE WITH IT. CURRENT SFC BASED CAPES ARE MAINLY BLO 1000J WITH THE HIGHEST CAPES (SE CWA) AT ODDS WITH THE BETTER DYNAMICS WHICH ARE W OF US. SO WE ARE EXPECTING MOST IF NOT ALL OF THE THUNDER THAT DOES OCCUR INTO THIS EVE TO REMAIN WELL BELOW SVR LIMITS. MODEL FCST SOUNDINGS DEVELOP A CAP OVERNIGHT AND WE DROPPED THE MENTION OF THUNDER. WE DID MAINTAIN LOWER POPS THOUGH AS ANOTHER SHORT WAVE IS FCST TO MOVE THRU OUR CWA. NO DIFFERENCES FROM MOS GUIDANCE. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... THE UPPER TROF IS FORECAST TO PASS ACROSS OUR CWA LATE IN THE NIGHT ON TUESDAY. THIS HAS TRENDED A BIT STRONGER AND MORE UNSTABLE THAN THE PAST TWO DAY SHIFT SOUNDING RUNS. THE PROTECTIVE CAP IS FCST TO BE GONE EVEN WITH THE WRF-NMMS FCST SOUNDINGS. PRETTY IMPRESSIVE 100KT PLUS JET ALSO FCST TO BE OVER OUR CWA. FCST CAPES ON THE GFS DO EXCEED 1000J AND SFC BASED LIFTED INDICES ARE FCST TO BE LESS THAN -5C. THIS IS OVERDONE AS ITS BASED ON FCST UPR 60S DEW POINTS. NEVERTHELESS EVEN TAKEN ABOUT 5F OFF THE DEW POINTS SHOULD BE ENOUGH FOR THUNDER AND WE WILL CONTINUE THE MENTION. THE FCST WBZ WILL BE IN A BETTER PLACE FOR HAIL AS THE OVERALL FREEZING LVL IS EXPECT TO DROP TO ABT 12K. WELL KEEP AN EYE ON WHAT OCCURS W OF US AS WE SHOULD HAVE A SIMILAR SCENARIO OVER OUR CWA ON TUE. SO SOME SMALL HAIL WOULD NOT BE OUT OF THE QUESTION. AS FAR AS THE FCST WIND FIELDS GO, THEY WILL BE VERY TOP HEAVY TOMORROW. ANYONE WITH ACCESS TO VISIBLE SATELLITES SHOULD SEE THE CB ANVILS GET BLOWN WELL UPSTREAM OF THE PARENT CELLS. BELOW 10K SOUTH AND 15K NORTH, THE FCST WIND FIELDS ARE QUITE WEAK, SO WEAK THAT THE 0-4KM BULK SHEARS ARE APPROACHING 10KTS, NOT EXACTLY ROBUST. THERE WILL BE SOME FCST DRY AIR BELOW 10K, BUT RIGHT NOW THE PULSE TYPE PARAMETERS (GENERALLY LESS THAN A 20C DROP OF EQUIVALENT PTNL TEMP WITH HEIGHT) IS NOT STELLAR. IN A PERFECT PROG WORLD, THIS WOULD BE AN SPS TYPE SCATTERED TSRA DAY WITH POSSIBLY SOME SMALL HAIL. THE POSITIONING OF THE H5 TROF AND THE FORECAST LOCATION OF THE DEEPER MOISTURE FAVORS A GREATER CHANCE IN THE NW PART OF OUR CWA THAN SE AND POPS ARE FCST IN THIS MANNER. MOS TEMPS LOOK GOOD BASED ON FCST H8 TEMPS AND THICKNESSES. THE GFS MDL H8 TEMP FCSTS HAVE WARMED ABOUT 3C FROM YDA AND NOW ITS MOS FCST IS ATTAINABLE BASED ON THOSE PARAMETERS. SOUNDS LIKE A BROKEN RECORD, BUT PRECIPITATION SHOULD DIMINISH WITH THE SETTING SUN ON TUESDAY NIGHT. THE GFS IS TRYING TO HINT AT POPS FOR OUR EASTERN ZONES ON WED, BUT ITS TOO HIGH DEW POINT DRIVEN AGAIN AND FOR AT LEAST ONE DAY WE WILL KEEP THAT DRY FCST GOING. FCST 1000-850MB THICKNESSES ARE ABOUT 6 HOURS TOO LATE FOR US TO REACH GFS MOS LEVELS AND WE WILL SIDE WITH THE LOWER ETA MOS MOST AREAS. NOT TOO MANY JULY DAYS WITH FCST DEW POINTS IN THE 50S, ENJOY IT. AS MUCH AS ONE CAN DO IT ON A JULY NIGHT, A DECENT RADIATIONAL COOLING NIGHT IS EXPECTED ON WED. && .LONG TERM /THURSDAY THROUGH MONDAY/... FOR THE LONG TERM PERIOD THE MODELS HAVE BEEN SETTLING INTO THEIR PERSPECTIVE CORNERS AS TO THE IMPENDING COLD FRONT, STALLING AND WAVES ALONG IT. AT LEAST ALONG THE LEADING EDGE THERE IS BETTER AGREEMENT WHICH ALSO SEEMS LOGICAL. PCPN CHANCES WILL INCREASE LATE IN THE DAY WITH THE HIGHEST CHANCES IN THE NORTHWEST ZONES. EACH AND EVERY MODEL KEEPS OUR SERN ZONES DRY THROUGH THURSDAY DAY AND THIS THOUGHT WILL BE FOLLOWED. MODEL FORECAST SOUNDINGS SHOW SOME PRETTY WARM AIR ADVECTING IN AT AROUND 925MB. REACHING 90F BY THE END OF THE DAY ALONG THE COASTAL PLAIN NOT OUT OF THE QUESTION. FRONT AND CONVECTION EXPECTED TO LOSE STEAM THU NIGHT WITH GENERALLY A LOW CHC MAINTAINED ACROSS OUR CWA. THEN THE DIFFERENCES START. THE ECMWF REMAINS AMONG THE NORTHERN ENVELOP OF MODEL SOLUTIONS WITH THE FRONTAL LOCATION WITH THE DGEX THE NEXT CLOSEST. THE UKMET/GFS AND CAN GGEM ALL FAVOR A MORE SOUTHERN (SOMETIMES SOUTH OF OUR CWA) SOLUTION OF THE FRONT AND WAVES ALONG IT. BELIEVE THE ECMWF SOLUTION WILL NOT COME TO FRUITION ONE BECAUSE OF ITS WARM BIAS AND ALSO IN EARLY JULY FRONTS TEND TO STILL MAKE SOME SOUTHWARD MOVEMENT INTO AND THROUGH OUR CWA. AS FOR THE HOLIDAY WEEKEND, OF THE THREE DAYS, SATURDAY (FAMOUS LAST WORDS) RIGHT NOW IS THE DAY WITH THE GREATEST MODEL CONSENSUS OF PCPN OCCURRING AND THEN IT SPLITS AGAIN AS TO WHETHER THE FRONTAL BOUNDARY WILL SLIP ENOUGH FAR TO THE SOUTH FOR SUNDAY AND HOW MUCH ACTIVITY WILL RIDE ALONG THE FRONTAL BOUNDARY FOR THE 4TH ITSELF. THE LATEST GFS HAS SLID TOWARD THE MCS TYPE SOLUTIONS THAT THE ECMWF HAS HAD FOR A COUPLE OF RUNS. THE LATEST GFS RUN FOR THE 4TH HAS A CONVECTIVE FEEDBACK LOOK TO IT, BUT WE HAVE FOUND IF CONSISTENCY OR AN EVERY OTHER RUN SHOWS IT, CHANCES ARE GREATER THAT IT WILL OCCUR. FIRST RUN WE HAVE SEEN THIS IN OUR CWA, SO WE WILL SEE WHERE IT GOES FROM HERE. LATEST HPC THINKING AND OUR SOLUTION WILL LEAN MORE TOWARD AN ENSEMBLE CONSENSUS. NONE OF THESE DAYS LOOKS LIKE IT WILL BE A TOTAL WASHOUT, JUST IF YOU HAVE OUTDOOR PLANS, JUST REMAIN ALERT FOR POSSIBLE CONVECTION AND HAVE CONTINGENCY PLANS. THERE IS ABOUT A 3-5C DIFFERENCE BETWEEN THE FCST H8 TEMPS OF THE ECMWF AND GFS IN THE LONGER TERM. THE TRUTH WILL PROBABLY LIE BETWEEN AS THE ECMWF SUMMER WARM BIAS AROUND US HAS CONTINUED SO FAR. MAX TEMPS WILL LEAN TOWARD THE HIGH END OF THE MEX MOS ENSEMBLE MEAN AND MIN TEMPS WILL GENERALLY BE ACCEPTED. && .AVIATION /02Z TUESDAY THROUGH SATURDAY/... THE PRECIPITATION THAT DEVELOPED DURING THE AFTERNOON AND EARLY EVENING HOURS IN OUR REGION SHOULD CONTINUE TO WEAKEN AND DISSIPATE BY 0400Z OR 0500Z. UNTIL THAT TIME, IT SHOULD HAVE LIMITED IMPACT ON KPHL, KILG, KMIV, KACY, KPNE, KTTN, KABE AND KRDG WITH A PASSING LIGHT SHOWER POSSIBLE, AT MOST. CONDITIONS ARE EXPECTED TO REMAIN VFR. FOR LATE TONIGHT, A MAINLY SCATTERED CLOUD COVER OF MID AND HIGH LEVEL CLOUDS IS EXPECTED. THE WIND WILL BE FAIRLY LIGHT. BEING THAT SOMEWHAT DRIER AIR HAS BUILT INTO OUR REGION, WE ARE EXPECTING ON SCATTERED VISIBILITY RESTRICTION FROM LATE TONIGHT INTO EARLY TUESDAY MORNING. WE HAVE MENTIONED MIST AT KRDG, KTTN AND KMIV. AS AN UPPER LEVEL DISTURBANCE FROM THE WEST MOVES CLOSER TO OUR REGION ON TUESDAY, WE ARE AGAIN EXPECTING SCATTERED AFTERNOON AND EARLY EVENING SHOWERS AND THUNDERSTORMS. FOR NOW, WE HAVE SIMPLY MENTIONED CUMULONIMBUS IN THE TAFS FOR THAT TIME PERIOD. OUTLOOK... MAINLY DRY WEATHER IS ANTICIPATED FRO WEDNESDAY INTO THURSDAY, WITH THE POSSIBILITY OF SHOWERS AND THUNDERSTORMS EXPECTED TO RETURN FOR THURSDAY NIGHT, FRIDAY AND SATURDAY. && .MARINE... SEAS DROPPED BELOW 5 FT THIS EVENING AND SHOULD STAY SO FOR THE NEXT FEW DAYS UNTIL LATER IN THE WEEK AROUND THE THURSDAY TIME PERIOD. WINDS THE NEXT SEVERAL DAYS SHOULD REMAIN BELOW SMALL CRAFT ADVISORY AS WELL AND REMAIN GENERALLY OUT OF THE SOUTH OR WEST DIRECTION. THE FRONT LOCATED JUST ALONG THE COAST WILL SLOWLY DRIFT OUT TO SEA TOMORROW WHILE A WEAK SURFACE TROUGH CROSSES THE AREA. THEREFORE WE COULD SEE SOME SHOWERS OR THUNDERSTORMS ON TUESDAY. WEDNESDAY WE SHOULD SEE A BREAK FROM THE RAIN, BUT BY THURSDAY ANOTHER FRONT DIPS DOWN AND STALLS OUT, WHICH MAY PRODUCE SHOWERS THROUGH THE END OF THE WEEK. && .CLIMATE... ANOTHER DAY CLOSER TO THAT TOP TEN JUNE. WE ARE HAVING A HOT START TO THE SUMMER OF 2008. IF THE MONTH ENDED YESTERDAY, IT WOULD BE THE 4TH WARMEST JUNE ON RECORD IN PHILADELPHIA: 78.0 DEGREES IN 1994 78.0 DEGREES IN 1925 76.7 DEGREES IN 1943 76.3 DEGREES THRU 6/29 76.2 DEGREES IN 1934 ATLANTIC CITY INTERNATIONAL: PUT A FORK IN IT RIGHT NOW ITS DONE. ITS LIKE TIGER WOODS HAVING THE LEAD GOING INTO THE LAST DAY OF A MAJOR, JUST HAVE TO WAIT FOR THE FINAL NUMBER TO BE POSTED 74.7 DEGREES THRU 6/29 73.6 DEGREES IN 1984 PRESENT RECORD.
