NWS Philadelphia/Mount Holly wrote its last area forecast discussion before the first event at Jun 26, 2:30 PM EST, 1 hour 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 330 PM EDT FRI JUN 26 2009 .SYNOPSIS... A COLD FRONT WILL MOVE THROUGH OUR REGION THIS EVENING, AND MOVE SLIGHTLY OFF THE COAST LATE TONIGHT. WEAK HIGH PRESSURE WILL APPROACH FROM THE WEST SATURDAY AND GENERALLY CONTINUE INTO SUNDAY, BUT A RETURN TO WEAK LOW PRESSURE COULD OCCUR LATER SUNDAY. HOWEVER, MORE UNSETTLED WEATHER IS POSSIBLE FOR MUCH OF THE COMING WEEK AS UPPER LEVEL LOW PRESSURE IS EXPECTED TO APPROACH SLOWLY FROM THE WEST, AND PERIODIC WEATHER DISTURBANCES ARE FORECAST TO MOVE THROUGH THE REGION. && .NEAR TERM /UNTIL 6 AM SATURDAY MORNING/... A COLD FRONT WAS MOVING INTO AN UNSTABLE AND MOIST AIRMASS OVER OUR REGION THIS AFTERNOON. CONVECTION WAS FIRING AT MID AFTERNOON, AND A SEVERE THUNDERSTORM WATCH IS IN EFFECT FOR ALL AREAS UNTIL 10 PM THIS EVENING. THE MAIN THREATS ARE DAMAGING WINDS AND LARGE HAIL, AS CAPES ARE FORECAST TO BE BETWEEN 2000 AND 3000 J/KG, AND LIFTED INDICES ARE FORECAST BETWEEN MINUS 4 AND MINUS 7. THE MOST UNSTABLE AIR APPEARED TO BE OVER OUR SOUTHERN NEW JERSEY ZONES, BUT DEW POINTS HAVE DROPPED OVER MANY AREAS. EVEN SO, AVAILABLE MOISTURE IS NOT LACKING. TEMPERATURES WERE HELD DOWN A BIT THIS AFTERNOON BECAUSE OF THE HIGH CLOUDS FROM EARLIER CONVECTION, BUT INSTABILITY IS RICH REGARDLESS. THE BEST WINDS FROM THE UPPER JET STREAK WILL BE AFFECTING OUR NORTHERN ZONES THROUGH THIS EVENING ALTHOUGH THE DYNAMICS ARE NOT AS GOOD FOR SOUTHERN ZONES, THE THERMODYNAMICS ARE PROBABLY BETTER SOUTH. PERHAPS CELLS WILL BE MORE SCATTERED SOUTH, WITH MORE ORGANZIED ACTIVITY NORTH AND CENTRAL. THE CONVECTION SHOULD WANE BY LATE THIS EVENING, PERHAPS CARRYING ON AT LOWER LEVELS FOR OUR SOUTHEASTERN AREAS NEARER TO THE FRONT AS DIURNAL EFFECTS SUBSIDE. && .SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY/... WITH THE UPPER LOW MOVING THROUGH OUR AREA SATURDAY MORNING, AND JUST TO THE EAST WITH A NORTHWEST FLOW SATURDAY AFTERNOON, IT WAS DECIDED TO KEEP IN ISOLATED PRECIPITATION FOR THE DAY, LEAVING THUNDER OUT OF THE FORECAST IN THE MORNING. THEN, NO WEATHER WAS MENTIONED SATURDAY NIGHT AND SUNDAY MORNING, BUT A SLIGHT CHANCE OF CONVECTION WAS KEPT FOR SUNDAY AFTERNOON IN VIEW OF THE NORTHWEST FLOW AND FORECASTER DISCRETION IT SEEMS THERE IS A PROPENSITY FOR A FEW CELLS TO DEVELOP WITH LITTLE PROVOCATION THESE DAYS. TEMPERATURES WERE GENERALLY HANDLED SIMILARLY BY THE MOS GUIDANCE SATURDAY AND SUNDAY, SO THE MAXES AND MINS WERE ACCEPTED WITH ONLY MINOR CHANGES MADE. && .LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/... MORE UNSETTLED WEATHER IS EXPECTED, MAINLY IN A DIURNALLY-DRIVEN FASHION, FOR MONDAY ANS TUESDAY. UPPER LEVEL LOW PRESSURE SETTING UP AND CLOSING OFF OVER THE EASTERN GREAT LAKES IS LIKELY TO SEND OCCASIONAL DISTURBANCES THROUGH OUR AREA, AND THEN, AS THE UPPER TROUGH NEARS OUR AREA LATER IN THE WEEK, CONTINUE TO CAUSE AT LEAST SCATTERED SHOWERS. TIMING IS UNCERTAIN, SO DIURNALLY- FAVORED AFTERNOONS AND EVENINGS WERE HIGHLIGHTED AT THIS POINT FOR CONVECTIVE DEVELOPMENT EARLY IN THE WEEK, THEN SHOWERS WERE BROAD- BRUSHED FOR WEDNESDAY THROUGH FRIDAY. GENERALLY, HPC GUIDANCE, INCLUDING TEMPERATURES, WAS FOLLOWED. && .AVIATION /19Z FRIDAY THROUGH WEDNESDAY/... THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY AND SURROUNDING AREAS. THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY AND SURROUNDING AREAS. THE 18Z TAF FORECASTS WILL INDICATE THE POSSIBILITY OF SHOWERS AND TSTMS INTO THE EVENING, THEN A BREAK WITH A RETURN CHANCE OF SHOWERS AROUND MIDNIGHT. VFR CONDITIONS COVERED THE REGION AT 18Z WITH ISOLATED SHOWERS DEVELOPING IN CENTRAL PA AND SOME SCATTERED SHOWERS OVER NRN NJ. THE AREA WITH TSTMS WAS CONFINED TO NY STATE AND EXTREME NRN PA. ALTHOUGH I CANNOT RULE OUT A POP UP SHOWER OR TSTMS AT ANYTIME THIS AFTN/EVENING DUE TO THE UNSTABLE AIR IN PLACE. HOWEVER, THE BEST TIME FOR SHOWERS AND TSTMS IS MID AFTN AT ABE/RDG AND LATE AFTN AND EARLY THIS EVENING FARTHER SOUTH. COVERAGE OF SHOWERS AND TSTMS IS EXPECTED TO BE GREATER AROUND ABE/RDG THAN FARTHER TO THE SOUTH. THE FORECAST AND TIMING OF THE AFTN/EVENING TSTMS IS BASED ON AN UPPER SHORT WAVE AS DEPICTED BY THE NAM. THERE SHOULD BE A LULL IN ANY CONVECTIVE ACTIVITY FOR A FEW HOURS DURING THE EVENING, BEFORE THE THREAT OF SHOWERS RETURNS AS A COLD FRONT MOVES THROUGH FROM THE NORTHWEST. IF WE HAVE ANY LEFTOVER UNSTABLE AIR IN PLACE, THIS COULD ALLOW FOR TSTM DEVELOPMENT, BUT FOR NOW I ONLY MENTION SHOWERS WITH CB DUE TO THE FRONTAL TIMING AND LOSS OF DAYTIME HEATING. DRIER AIR RETURNS LATE TONIGHT WITH A NW FLOW DEVELOPING. AREAS THAT GET RAIN OVERNIGHT COULD SEE SOME LIGHT FOG EARLY IN THE MORNING. FOR NOW, I ONLY WILL MENTION THE VSBY RESTRICTIONS AS MVFR AT RDG/ABE AND LEAVE OTHER AREAS VFR SINCE IT WOULD CLEAR OUT LATER FARTHER SOUTH. ON SATURDAY...DAYTIME HEATING SHOULD ALLOW GOOD MIXING DURING THE DAY AND GUSTY NW WINDS OF 20 KTS SHOULD DEVELOP IN THE AFTN. VFR CONDITIONS ARE FORECAST. AN ISOLATED TSTM COULD DEVELOP IN THE AFTERNOON BUT MOST AREAS SHOULD MISS THEM. OUTLOOK... THERE IS THE THREAT FOR SCATTERED SHOWERS AND TSTMS FROM SUNDAY THROUGH THE EARLY PART OF THE WEEK WITH THE BEST CHC DURING THE AFTN OR EVENING HRS. && .MARINE... A COLD FRONT WILL MOVE THROUGH FROM THE NORTHWEST TONIGHT. SCATTERED SHOWERS AND TSTMS ARE POSSIBLE THIS EVENING WELL AHEAD OF THE FRONT AND THEN A SECOND ROUND OF SHOWERS IS POSSIBLE DURING THE MIDDLE OF THE NIGHT WITH THE ACTUAL COLD FRONTAL PASSAGE. ANOTHER COLD FRONT IS EXPECTED TO MOVE THROUGH EARLY MONDAY. EVEN WITH THE TWO COLD FRONTS IN THE FORECAST, WE ARE EXPECTING CONDITIONS TO REMAIN BELOW SMALL CRAFT ADVISORY CRITERIA THROUGH WEDNESDAY. THE ONLY EXCEPTION IS THE POSSIBILITY OF STRONG WIND GUSTS WITH THIS EVENINGS THUNDERSTORMS. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...NONE. NJ...NONE. DE...NONE. MD...NONE.
