Area forecast discussion, Aug 3, 2:30 PM EST, 4 hours 31 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 330 PM EDT FRI AUG 3 2007 .SYNOPSIS... A WEAK FRONT WILL CROSS THE AREA TONIGHT AND THEN WASH OUT AS IT MOVES ACROSS THE LOWER DELAWARE VALLEY AND SOUTHERN NEW JERSEY SATURDAY. HIGH PRESSURE WITH DRIER AIR WILL BUILD IN FROM THE NORTH ON SATURDAY, BUT TEMPERATURES WILL REMAIN VERY WARM TO HOT ACROSS THE AREA. FAIR WEATHER SHOULD LAST INTO SUNDAY, BUT AN APPROACHING WARM FRONT MAY BRING SOME CLOUDS TO THE REGION LATER SUNDAY. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... THE REGIONAL RADAR GRAPHIC SHOWS SCATTERED THUNDERSTORMS DEVELOPING IN THE HOT AND HUMID AIR MASS AHEAD OF THE APPROACHING FRONT. THE FRONT SHOWS UP WELL LINING UP FROM NE NY STATE AND IT EXTENDS SW INTO WESTERN PA. HIGH CAPES AND SLOW MOVEMENT TO THE STORMS MAY BRING SOME LOCALIZED FLOODING WITH ANY THUNDERSTORM TONIGHT. THE AREAL COVERAGE OF THE RAINS WILL NOT BE GREAT SO THEREFORE I WILL KEEP ONLY CHC POPS IN FOR OUR AREA THROUGH THE EVENING, IGNORING THE POPS OFFERED BY MET AND MAV. THE FRONT IS WEAKENING AND WILL SLOWLY DIE OUT AS IT APPROACHES THE MASON-DIXON LINE SATURDAY AFTERNOON. SOMEWHAT DRIER AIR WILL FILTER IN ACROSS THE AREA BEHIND THE FRONT. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY/... THE SHORT TERM PART OF THE FORECAST WILL BE DRY FOR THE MOST PAST. I HAVE DECIDED TO WRITE IN SOME CHC POPS ACROSS THE DELMARVA FOR SATURDAY AFTERNOON WITH SOME RESIDUAL CAPE AND LOW LEVEL MOISTURE STILL IN PLACE. THIS WILL NOT GET SWEPT AWAY SINCE THE FRONT WILL NOT MOVE THROUGH THOSE AREAS UNTIL LATER IN THE DAY. CAPE VALUES BY AFTERNOON WILL BE IN THE 1000 TO 2000 J/KG RANGE AND ITS POSSIBLE THAT A SEA BREEZE MAY TOUCH OFF SOME ACTIVITY. SFC WINDS WILL SWITCH AROUND TO NE THEN E FROM SAT NIGHT THROUGH SUNDAY AS A SFC HIGH MOVES BY TO THE NORTH. THE FLOW OFF THE OCEAN WILL LIKELY KEEP THINGS MORE STABLE FOR SUNDAY. THIS, ALONG WITH THE FACT THAT UPPER HEIGHTS WILL RIDGE ACROSS THE AREA ON SUNDAY, HAVE LED ME TO NOT INCLUDE ANY SHOWERS IN THE FCST FOR SUNDAY. && .LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/... HPC GRAPHICS DEPICT A WAVY FRONTAL ZONE WHICH WILL MEANDER ACROSS THE AREA FOR MUCH OF THE EXTENDED PERIOD. ITS DIFFICULT TO PIN DOWN EXACTLY WHICH TIMES WILL HAVE THE GREATEST CHANCES FOR SHOWERS AND THUNDERSTORMS. IT LOOKS LIKE THE FIRST WARM FRONT APPROACH SUNDAY NIGHT WILL BE ACCOMPANIED BY SCATTERED ACTIVITY ACROSS THE REGION, SO POPS HAVE BEEN BUMPED UPWARD INTO THE CHC CATEGORY WITH THIS PACKAGE. THE POPS FOR THE AFTERNOON EARLY EVENING PERIODS OF MONDAY AND TUESDAY WERE RAISED TOO AS THE FRONT AND DAYTIME HEATING SHOULD PRODUCE AT LEAST SOME ACTIVITY ACROSS THE AREA. SLIGHT CHC POPS WERE PAINTED FOR THE REMAINDER OF THE EXTENDED PERIOD FOR NOW. TEMPERATURES WILL BE SEASONABLY WARM FOR THE EXTENDED TIME FRAME AND IT WILL BE FAIRLY HUMID TOO. && .AVIATION /19Z FRIDAY THROUGH WEDNESDAY/... AT 3:00 PM, THERE WERE FEW TO SCATTERED CUMULUS OVER OUR FORECAST AREA WITH SOME CONVECTION UP IN THE POCONOS AND ALSO TO OUR WEST SOUTHWEST NEAR BALTIMORE. WERE EXPECTING ADDITIONAL SHOWER AND TSTM ACTIVITY TO DEVELOP IN OUR REGION DURING THE BALANCE OF THE AFTERNOON INTO THE EARLY EVENING. THE ACTIVITY SHOULD REMAIN ISOLATED TO SCATTERED. AS A RESULT, WEVE SIMPLY INDICATED CUMULONIMBUS IN OUR TAFS. AFTER SUNSET, THE PRECIP AND THE CUMULUS SHOULD BEGIN TO DISSIPATE. FOR EARLY SATURDAY MORNING, WEVE INDICATED MVFR VSBY VALUES AT KRDG, KABE, KTTN, KMIV AND KACY. IN THE PERIOD FROM SATURDAY THROUGH WEDNESDAY, THERE MAY BE ISOLATED TO SCATTERED SHOWER AND THUNDERSTORM ACTIVITY, MAINLY DURING THE AFTERNOON AND EVENING HOURS EACH DAY. A FRONTAL BOUNDARY IS FORECAST TO DROP DOWN THROUGH THE FORECAST AREA ON SATURDAY NIGHT THEN IT SHOULD RETURN TO THE NORTH ON SUNDAY NIGHT. OTHERWISE, THERE WILL BE A CONTINUATION OF THE HEAT AND HUMIDITY, WITH LATE NIGHT AND EARLY MORNING VISIBILITY RESTRICTIONS POSSIBLE EACH DAY. && .MARINE... HIGH PRESSURE LOCATED OVER THE ATLANTIC WILL CONTINUE TO INFLUENCE THE REGION INTO SATURDAY WITH A BROAD SOUTHERLY FLOW. A WEAK FRONTAL BOUNDARY IS FORECAST TO APPROACH FROM THE NORTHWEST AND IT SHOULD REACH THE COASTAL WATERS OF NEW JERSEY AND DELAWARE ON SATURDAY NIGHT. THE WIND IS EXPECTED TO VEER AROUND TO THE NORTHWEST LATE ON SATURDAY NIGHT, THEN TO THE EAST THEN SOUTHEAST ON SUNDAY. THE FRONTAL BOUNDARY IS FORECAST TO RETURN TO THE NORTH ON SUNDAY NIGHT WITH SOUTHERLY WINDS AGAIN ANTICIPATED FOR THE FIRST HALF OF THE NEW WEEK. WIND SPEEDS SHOULD REMAIN BELOW 15 KNOTS THROUGH MUCH OF THE PERIOD, WITH WAVES ON THE OCEAN WATERS STAYING IN THE 2 TO 4 FOOT RANGE. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...NONE. NJ...NONE.
