Area forecast discussion, Jun 28, 8:45 AM EST, 5 hours 30 minutes before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 945 AM EDT TUE JUN 28 2005 ...UPDATE... HAVE UPDATED THE MORNING PACKAGE TO LOWER POPS ACROSS THE NORTHERN ZONES AS PRECIP IS MOVING OUT OF EXTREME NORTHERN SUSSEX COUNTY NEW JERSEY AT THIS TIME. ALSO REMOVED TEMPORAL REFERENCES AND CLEANED UP WORDING TO JUST INDICATE THE POTENTIAL FOR AFTERNOON SHOWERS AND THUNDERSTORMS AND MADE SOME ADJUSTMENTS TO CLOUD COVER WORDING. OTHERWISE CURRENT FCST LOOKS ON TRACK. ********************************************************************* 305 AM EDT TUE JUN 28 2005 PREVIOUS DISCUSSION... .SHORT TERM (TODAY THROUGH THURSDAY)... THE LAST OF THE SUBTROPICAL WAVE WILL MOVE NE AND AWAY FROM THE AREA EARLY THIS MORNING. AT 6Z THE LOW WAS NEAR TTN AND DRIFTING N. N OF THE LOW WAS OCCASIONAL RAIN. SOME SHOWERS LINGERED S OF THE LOW BUT WERE DISSIPATING RAPIDLY AS AN AREA OF SUBSIDENCE SHOWING ON THE SATELLITE AND CONFIRMED BY DRYING ON THE WATER VAPOR SATL PICS MOVES IN BEHIND THE LOW. THIS WILL SPREAD OVER THE ENTIRE REGION THIS AFTN GENERALLY SUPPRESSING CONVECTION. HOWEVER, ENOUGH MOISTURE REMAINS THIS AFTN, THAT WHEN COMBINED WITH DAYTIME HEATING, COULD DVLP AFTN/EVENING RW/TRW. WITH THE SUBSIDENCE SHOULD BE SOME SUNSHINE AND ENOUGH FOR A PTLY SUNNY FCST. TEMPS SHOULD WARM AND MAV TEMPS LOOK OK OR A BIT LOW TODAY. TONIGHT...ANY CNVCTN THAT FORMS THIS AFTN WILL PROBABLY GO INTO THE EVENING, THEN GENERALLY DRY CONDITIONS WILL BE FCST ALTHOUGH SOME WIDELY SCTD RW/TRW COULD CONTINUE TO DVLP. WED AND WED NIGHT...THE UPPER AIR CHANGES GRADUALLY. ACTUALLY IT STARTS LATE TONIGHT. ALL MODEL GENERALLY AGREE THAT THE LARGE HIGH EXTENDING FROM THE ATLC SEABOARD EASTWARD WILL GRADUALLY SHIFT SE AS A TROUGH DEVELOPS OVER THE OHIO/TENN VALLEYS. THIS FLOW IS FCST TO TAP INTO THE DEEPER TROPICAL MOISTURE COMING OUT OF THE GULF OF MEXICO. ALTHOUGH SHORT WAVES WILL BE HARD TO TIME WITHIN THE FLOW AND THE MODELS GENERALLY DO POORLY FCSTG THE DETAILS WELL, ESPECIALLY BEYOND 24 HRS, THE MODELS DO SHOW SHORT WAVES LINING UP, ONE-AFTER-ANOTHER FROM THE GULF NE THROUGH THE MID ATLC STATES, MEANING SHOWERS AND TSTMS BECOMING LIKELY (POP 60/70) WED AND WED NIGHT WITH THE BEST CHANCES IN THE AFTN AND EVENING CONSIDERING DIURNAL TRENDS. ALSO, PRECIPITABLE WATER GOES BACK UP ABOVE 2 INCHES. THEREFORE, ANY RW/TRW THAT DVLP COULD HAVE TORRENTIAL DOWNPOURS. WE WILL ISSUE AN SPS INDICATING THIS. THU...THE SHORT WAVES SHIFT A BIT TO THE EAST THURSDAY, SO POPS WILL BE DROPPED A BIT BACK TO 50 FOR THU. && .LONG TERM (THURSDAY NIGHT THROUGH MONDAY)... RELATIVELY LITTLE CHANGE HAS BEEN MADE TO THE EXTENDED. SHOWERS AND TSTMS REMAIN POSSIBLE WITH THE WARM MOIST AIRMASS IN PLACE THURSDAY NIGHT. ON FRIDAY, A COLD FRONT MOVES DOWN FROM THE NORTHWEST BRINGING COOL/DRIER AIR DOWN FROM CANADA. HIGH PRESSURE BUILDS IN BEHIND THE COLD FRONT FRIDAY NIGHT THROUGH MONDAY. && .AVIATION... WIDESPREAD IFR/MVFR CONDITIONS ACROSS THE TAF SITES THIS MORNING WITH KACY DROPPING DOWN TO LIFR RECENTLY. RADAR IMAGES SHOW THE CIRCULATION AROUND THE LOW PRESSURE SYSTEM ACROSS CENTRAL NJ. IT LOOKS LIKE THE FORWARD SPEED OF THE SYSTEM HAS INCREASED LATELY. THE 11-3.9 MICRON SATELLITE PICS REVEAL THE BACK EDGE OF THE LOW CLOUDS SLOWLY MOVING NORTHEASTWARD ACROSS MD AND SOUTHERN DE. I EXPECT THAT THE CIGS AND VSBY WILL SLOWLY IMPROVE TO VFR FROM SOUTH TO NORTH TODAY. THE ABUNDANT LOW LEVEL MOISTURE AND THE FACT THAT THERE WILL BE SOME SUNSHINE TODAY LEADS ME TO LEAVE MENTION OF A THUNDERSTORM IN THE AFTERNOON PERIODS (BY USING A CB CLOUD GROUP). THE OVERALL PROBABILITY AND COVERAGE WILL BE SCT AT BEST. && .MARINE... SOUTHERLY WINDS EXPECTED OVER THE COASTAL WATERS AND DE BAY FOR THE SHORT TERM PERIOD. WIND SPEEDS AROUND 10 TO 15 KTS TODAY AND 15 TO 20 KTS ON WED. WAVE HEIGHTS GENERALLY 3 TO 4 FT ALONG THE COAST TODAY AND WED. TROPICAL AIR MASS WILL PRODUCE SCT THUNDERSTORMS THIS AFTERNOON AND WED. THUNDERSTORMS WILL CONTAIN DOWNPOURS AND FREQUENT LIGHTNING. WAVEWATCH INDICATED THAT SEAS WILL INCREASE TO 5 TO 7 FT ON THURSDAY...BUT STILL TO EARLY TO HEADLINE IT IN THE CWF. WITH THE LEFTOVER SWELLS FOR THE SUBTROPICAL WAVE, MODERATE RIP CURRENTS SHOULD CONTINUE INTO THIS MORNING AND PROBABLY DIMINISH THIS AFTERNOON. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...NONE. NJ...NONE. DE...NONE. MD...NONE. MARINE...NONE. && UPDATE...NIERENBERG SHORT TERM/LONG TERM...RNS AVIATION/MARINE...PO
