NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Jun 29, 2:15 PM EST, 40 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 315 PM EDT SUN JUN 29 2008 .SYNOPSIS... A COLD FRONT OVER THE EASTERN GREAT LAKES WILL MOVE THROUGH THE REGION LATE TONIGHT. ANOTHER COLD FRONT IS EXPECTED TO MOVE THROUGH MONDAY EVENING WHILE THE UPPER AIR DISTURBANCE DRIVING THESE SYSTEMS PASSES THROUGH ABOUT TUESDAY EVENING. ON WEDNESDAY A HIGH PRESSURE SYSTEM WILL MOVE OVER THE AREA. ANOTHER COLD FRONT IS FORECAST TO REACH THE GREAT LAKES ON THURSDAY AND MOVE INTO AND THEN STALL OVER OR CLOSE TO THE REGION ON FRIDAY INTO THE WEEKEND. && .NEAR TERM /THROUGH TONIGHT/... THE GFS INITIALIZATION HAS CAUGHT UP TO THE WRF-NMM AND BOTH LOOKED PRETTY CLOSE WITH THEIR INITIALIZATION. THE ONE ODD COINCIDENCE THE 12Z IAD SOUNDING COULD NOT MEASURE ANY WINDS (NOT THAT THE WINDS WERE CALM). MEANWHILE BOTH THE GFS AND WRF-NMM INITIALIZED WITH CALM WINDS AROUND THE D.C. AREA. AT 850MB. SW FLOW EVENTS AGAIN PROVING TO BE MESSY AS LEFTOVER CLOUDS FROM YESTERDAY HAVE MUDDIED THE ATMOSPHERE PER SE. INSTEAD OF A CLEAN SLATE, WE FIND POCKETS OF CLOUDINESS WITH REDUCED INSTABILITY ACROSS THE REGION. THE WRF-NMM IS PICKING UP THESE FEATURES THE BEST. THE GREATEST INSTABILITY IS OVER CENTRAL AND SOUTHEASTERN NEW JERSEY AND ON CUE THE TSRAS ARE POPPING ACROSS THE REGION WITH POSSIBLY SEVERE STORM IN MONMOUTH COUNTY. IT LOOKS AS THOUGH THE SEVERE WEATHER THREAT WILL COME IN A COUPLE OF STAGES. THE FIRST IS OVER THE SOUTHEASTERN PART OF OUR CWA WHERE THE SUNSHINE HAS REMAINED THE STRONGEST AND SFC BASED CAPES HAVE EXCEEDED 2000J. THIS LOOKS LIKE MULTI-CELLULAR TYPE SVR AS THE 0-4KM FCST SHEAR IS ABOUT 20 KNOTS AND CURRENT KDIX VAD SHOWS ABOUT 25KTS OF WIND AT THE LLJ LEVEL. THE SECOND IS UP IN THE NORTHEASTERN PART OF OUR CWA WHERE DIFFERENTIAL HEATING WILL CONTINUE TO FIRE THE TSRAS. THIS IS ALSO THE LOCATION WHERE THE INCREASING LLJ IS FORECAST AND OUR FIRST SVR. THE GFS AND WRF-NMM HAVE FLIPPED OVER EACH OTHER WITH THE GFS NOW FCSTG THE STRONGER LLJ OF 35-40KTS. BESIDE THE SVR THREAT ONE HAS TO LOOK FOR BACK BUILDING TSRAS AND HEAVY RAIN IN THIS REGION AND LASTLY THE SHEAR IN THIS LOCATION WOULD HAVE THE GREATER SUPPORT FOR SUPERCELL TYPE STORMS. THE GFS FCST PARAMETERS FOR SUPERCELL TYPE STORMS IN OUR CWA IS HIGHEST IN THIS AREA. LASTLY A LINE OF CONVECTION HAS FORMED IN NWRN PA AND CONVECTION LIKES TO POP ALONG THE BLUE RIDGES. THIS MIGHT AFFECT OUR CWA THIS EVENING. THERE (IN PA) IS SOME CLOUDINESS AND A RELATIVE LOWER AREA OF INSTABILITY THAT THE TSRAS WILL HAVE TO OVERCOME. WE CONTINUED THE THREAT OF TSRAS THROUGH THE NIGHT AS THE AIR MASS REMAINS SUPPORTIVE OF TSRAS, BUT BELIEVE THIS IS MORE OF A TRADITIONAL THREAT OF THE SVR WX OCCURRING DURG THE FIRST HALF OF THE NGT AS STAB PARAMETERS DO NOT INCREASE OVERNIGHT AND THE LLJ LIFTS INTO NEW ENGLAND. UPSHOT WE WILL CONTINUE THE ENHANCED WORDING AND SIMILAR POPS. GUIDANCE MINS REMAIN PRETTY TIGHTLY CLUSTERED AND WILL BE USED. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... THE LONG WAVE TROF IS FORECAST TO REMAIN W OF OUR CWA ON MONDAY AND THE ENVIRONMENTAL WIND FIELD AT THE JET LEVEL LOOKS MORE CONDUCIVE TO PCPN THAN TDY WHERE THE H2.5 JET IS LATE IN ARRIVING. THE DOWNSIDE IS THAT THE FIRST COLD FRONT SHOULD FLUSH SOME OF THE LOW LEVEL MOISTURE. LOW LEVEL MOISTURE IS NOT AT A PREMIUM AS THIS MORNINGS 850MB ANALYSIS IS NOT SHOWING A PLETHORA OF +15C DEW POINTS UPWIND. SO BASICALLY WHAT WE HAVE IS AN AIR MASS THAT REMAINS CONDUCIVE TO SEVERE BECAUSE OF MID LEVEL DRY AIR AND THE JET ALOFT, BUT THE LOW LEVEL MOISTURE MAY BE LACKING. THIS SEEN IN THE FORECAST SOUNDINGS WHERE A CAP COMES PERILOUSLY CLOSE TO PUTTING A LID ON ALL ACTIVITY. WE KEPT POPS IN THE CHC CATEGORY BECAUSE OF THIS. HIGHEST POPS ARE FEATURED IN THE NW ZONES WHERE OROGRAPHICS USUALLY HELP ON DAYS LIKE THIS AND ALSO THERE CLOSER PROXIMITY TO THE CHANNELIZED VORT MAXES. MAX TEMP GUIDANCE LOOKS QUITE GOOD BASED ON FCST 1000-850MB THICKNESSES. THE WRF-NMM DISSIPATES THE FCST CAP DURING THE EVENING GIVING OUR CWA THE GREATEST THREAT FOR PCPN AT THAT TIME WHILE THE GFS DOES NOT. THE CAN RGEM DOES NOT SEEM THAT GONZO FOR PCPN AFTER 8 PM MON. FOR NOW WE COMPROMISED SINCE TIMING OF THE FEATURES INVOLVED WILL NOT BE PERFECT AND THERE WAS NO CLEAR CUT INITIALIZATION LEADER. WE KEPT PRECIP CHANCES THRU MON EVE. THE UPPER TROF IS FORECAST TO MOVE THROUGH OUR CWA LATE IN THE DAY TUESDAY. IN SPITE OF COLDER AIR ALOFT, THE FTHR DEPLETION OF LLVL MOISTURE REDUCES THE CHANCES OF PCPN. WE WILL NOT GO AS FAR AS TO REMOVE CHANCES AS THE ATMOSPHERE IN SUMMER OFTEN FINDS A WAY, BUT THERE IS NO FCST CAPE OR NEGATIVE SFC BASED L.I. ATTM. WE WILL KEEP PTYPE AS SHRA. GFS MOS IGNORES THE 2-3C COOLER FCST TEMPS AT 850MB THAN THE WRF-NMM AND HAS FCST MAX TEMPS VERY CLOSE TO ETA MOS. FOR NOW IT APPEARS THAT MOS GUIDANCE HAS A VERY GOOD HANDLE ON THE EVOLVING SITU AND WILL FOLLOW. AS THE UPPER AIR TROF SLIDES EAST, SO WILL END THE THREAT FOR PCPN (WELL AT LEAST FOR ONE DAY). && .LONG TERM /WEDNESDAY THROUGH SUNDAY/... WEDNESDAY REMAINS THE LONE HIGH CONFIDENCE DRY DAY IN THIS LONG TERM PERIOD AS HIGH PRESSURE CRESTS OUR CWA. A COLD FRONT WILL APPROACH THE REGION FROM THE NORTHWEST ON THURSDAY. MOST OF THURSDAY DAY STILL SHOULD BE DRY WITH GREATEST CONFIDENCE OF THIS REMAINING SO FOR THE SHORE LOCATIONS AND SERN PARTS OF OUR CWA. UNFORTUNATELY JUST IN TIME FOR THE HOLIDAY WEEKEND THE FRONT SAGS SOUTHWARD AND THEN IS EXPECTED TO STALL CLOSE TO OUR CWA COME FRIDAY AND REMAIN AN ACTIVE BOUNDARY THROUGH THE WEEKEND. THE 00Z GFS AND ECMWF FLIPPED FROM YESTERDAY WITH THE GFS MORE OPTIMISTIC FOR THE 4TH THAN THE ECMWF. THE 12Z GFS HAS SINCE NUDGED THE FNTL BOUNDARY MORE TO THE NORTH. ALSO FROM THE 4TH INTO THE HOLIDAY WEEKEND MOST OF THE MEDIUM RANGE MODELS FAVOR THE SOUTHERN HALF OF OUR CWA TO HAVE MORE ACTIVITY WHILE THE ECMWF FAVORS THE NORTH. EITHER WAY WE WILL BE CARRYING PRECIPITATION FOR NOW FOR THE HOLIDAY WEEKEND. WE HAVE SIDED CLOSER TO THE HIGHER (WARMER) ENSEMBLE MEMBERS OF MEX MOS FOR HIGH TEMPS AS THEY SEEM IN LINE FOR EARLY JULY DAYS WITH SOME SUNSHINE. && .AVIATION /19Z SUNDAY THROUGH FRIDAY/... EXCEPT FOR THE WIDELY SCATTERED TSTMS, VFR CONDITIONS PREVAIL TODAY WITH SCT TO BKN SC/AC AND CI ABOVE. THE SHWRS/TSTMS ARE EXPECTED TO BECOME MORE WIDESPREAD THROUGH THE EVENING HOURS. CONDITIONS IN THE STORMS WILL DROP TO MVFR/IFR. THE GREATEST THREAT FOR TSTMS WILL BE FROM 5 PM TO MIDNIGHT. WILL CONTINUE TO CARRY A TEMPO GROUP IN THE TAFS FOR THE LOWER CONDITIONS IN THE STORMS. LATER TONIGHT, EXPECT SOME FOG TO FORM, ESPECIALLY IN AREAS THAT GET RAIN THIS EVENING. CONDITIONS WILL LOWER TO MVFR/IFR BUT COULD DROP TO LIFR BRIEFLY BEFORE SUNRISE. ONCE HEATING BEGINS, VFR CONDITIONS WILL RETURN. FOR THE OUTLOOK PERIOD...MORE SCATTERED TO BROKEN AFTERNOON AND EVENING CONVECTION IS EXPECTED TOMORROW, WITH A SLIGHT CHANCE TUESDAY AFTERNOON AND EVENING DESPITE DRIER AIR AND LESS INSTABILITY. CONDITIONS WILL BE MOSTLY VFR OUTSIDE OF CONVECTION AND EARLY MORNING FOG, HOWEVER. DRY CONDITIONS AND VFR WEATHER ARE FORECAST TO PREVAIL WEDNESDAY AND THURSDAY. A FRONTAL ZONE WILL SLOWLY CROSS THE FORECAST AREA THURSDAY NIGHT AND FRIDAY WITH OUR NEXT BATCH OF INCLEMENT WEATHER. && .MARINE... THE SOUTHERLY FLOW HAS FINALLY BROUGHT SEAS ON THE OCEAN UP TO SMALL CRAFT ADVISORY CRITERIA. GUSTY WINDS WILL CONTINUE INTO TONIGHT BUT WILL DROP OFF LATER TONIGHT AS A WEAK FRONTAL ZONE MOVES ACROSS. SEA HEIGHTS ARE FORECAST TO LOWER MONDAY MORNING, BUT MAY NOT DROP BELOW SMALL CRAFT ADVISORY CRITERIA UNTIL LATE MORNING. WILL EXTEND THE ADVISORY UNTIL NOON TO COVER THIS. WAVEWATCH ACTUALLY BRINGS SEAS BACK UP TO 5 FT LATER IN THE DAY. WILL LET FUTURE SHIFTS DETERMINE WHETHER OR NOT THIS WILL HAPPEN, AND IF IT DOES, WHETHER THE ADVISORY WILL NEED TO BE EXTENDED. ANOTHER FRONT WILL WORK ACROSS THE AREA MONDAY NIGHT. DESPITE DRIER AIR AND LESS INSTABILITY, YET ANOTHER WEAK FRONT WILL CROSS THE AREA LATER TUESDAY AND TUESDAY EVENING, POSSIBLY SPARKING ISOLATED CONVECTION. HIGH PRESSURE AND DRIER AIR WILL THEN BUILD IN WEDNESDAY INTO THURSDAY AND YIELD BENIGN MARINE WEATHER BEFORE ANOTHER FRONT ARRIVES IN THE AREA THURSDAY NIGHT OR FRIDAY. && .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 5TH WARMEST JUNE ON RECORD IN PHILADELPHIA: 78.0 DEGREES IN 1994 78.0 DEGREES IN 1925 76.7 DEGREES IN 1943 76.2 DEGREES IN 1934 76.1 DEGREES THRU 6/28.
