Area forecast discussion, Jun 11, 12:50 PM EST, 2 hours 7 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 150 PM EDT MON JUN 11 2007 .SYNOPSIS... FOR TODAY AND TUESDAY, OUR REGION WILL REMAIN BETWEEN LOW PRESSURE CENTERED WELL OFF THE COAST AND HIGH PRESSURE LOCATED OVER THE GREAT LAKES. A COLD FRONT IS FORECAST TO DROP DOWN FROM THE NORTHEAST ON WEDNESDAY. HIGH PRESSURE IS EXPECTED TO FOLLOW FOR THE END OF THE WEEK. WARMER AND MORE HUMID AIR SHOULD BEGIN TO BUILD IN FROM THE WEST DURING THE WEEKEND. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... A NARROW LINE OF SCT-BKN CLOUDS SHOW UP VERY CLEARLY ON THE VISIBLE SATELLITE PICTURES THIS MORNING. THESE CLOUDS ARE ASSOCIATED WITH THE WESTERN FRINGES OF THE LOW PRESSURE SYSTEM SITTING OVER THE WESTERN ATLANTIC OCEAN. SHOWERS WITH THESE CLOUDS GRADUALLY DISSIPATED THIS MORNING, BUT GIVEN THE STRONG JUNE SUN, INSTABILITY SHOWERS AND THUNDERSTORMS ARE POSSIBLE AGAIN THIS AFTERNOON. AT 11 AM...CUMULUS CLOUDS ARE ALREADY DEVELOPING OVER NEW JERSEY AND EXTREME EASTERN PA, SO PARTLY CLOUDY STILL LOOKS GOOD FOR THIS AFTERNOON. WITH A GENERALLY LIGHT NORTHERLY FLOW ACROSS THE AREA, A SEABREEZE IS EXPECTED THIS AFTERNOON WHICH WILL TURN THE WINDS OVER THE EAST OR SOUTHEAST NEAR THE COAST. HIGH TEMPS IN THE 80S, AS ADVERTISED IN THE PREVIOUS FORECAST, STILL LOOK GOOD. && .SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/... AS MOISTURE AND BITS OF ENERGY CONTINUE TO ROTATE AROUND THE LOW OVER THE WESTERN NORTH ATLANTIC, WELL CONTINUE TO MENTION PARTLY TO MOSTLY CLOUDY SKIES ALONG WITH CHANCE POPS FOR MUCH OF THE PERIOD. GUIDANCE SEEMS TO SUGGEST A BREAK IN THE PRECIP FROM LATE THIS EVENING INTO TUESDAY MORNING. WEVE REINTRODUCED CHANCE POPS FOR TUESDAY AFTERNOON, WITH THE STRONG JUNE SUN AGAIN EXPECTED TO CREATE ENOUGH INSTABILITY FOR THE DEVELOPMENT OF SCATTERED SHOWERS AND TSTMS AT THAT TIME. WITH THE BACK DOOR COLD FRONT DROPPING DOWN FROM THE NORTHEAST EARLY ON WEDNESDAY, WEVE OPTED TO KEEP THE CHANCE POPS GOING FROM TUESDAY EVENING THROUGH TUESDAY NIGHT AND INTO WEDNESDAY. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... HIGH PRESSURE IS FORECAST TO BUILD DOWN FROM THE NORTHEAST IN THE WAKE OF THE BACK DOOR COLD FRONT. RELATIVELY COOL AND DRY WEATHER IS EXPECTED FOR THURSDAY, FRIDAY AND SATURDAY. THE MID LEVEL LOW OVER THE WESTERN NORTH ATLANTIC SHOULD BEGIN TO MOVE TO THE EAST OVER THE WEEKEND, ALLOWING WARMER AND MORE HUMID AIR TO BUILD INTO OUR REGION FROM THE WEST. && .AVIATION /18Z MONDAY THROUGH FRIDAY/... VFR CONDITIONS AT PRESS TIME EARLY THIS AFTERNOON BUT VISIBLE SATELLITE PICTURES SHOW CUMULUS CLOUDS DEVELOPING OVER NJ... NORTHERN DE AND EASTERN PA. 88D IS JUST BEGINNING TO SHOW SOME SHOWER ACTIVITY IN SOUTHEAST PA WEST OF PHL. NO THUNDERSTORMS YET, BUT THAT COULD CHANGE AT ANY MINUTE GIVEN THE INSTABILITY WHICH CAN BE CREATED WITH THE JUNE SUN. INSTEAD OF TAGGING ON A /CB/ ON THE CLOUD GROUPING IN EACH TAF, DECIDED ON INCLUDING /VCSH/ IN MOST TAFS THIS AFTN TO ACCOUNT FOR POSSIBLE PRECIPITATION. NO STRONG ONSHORE FLOW HAS DEVELOPED YET, THANKS TO THE POSITION OF THE LOW WELL OFF THE COAST. HAVE NOTED A GENERALLY NORTH TO NORTHWEST FLOW IN THE TAFS THROUGH THIS EVENING BEFORE EDGING INTO A NORTH-NORTHEAST FLOW DURING THE OVERNIGHT HOURS. HAVE ALSO INCLUDED A MENTION OF -SHRA DURING THE OVERNIGHT HOURS SINCE SOME OF THE MODELS ARE HINTING AT A SIGHTLY HIGHER POP BETWEEN 06Z AND 12Z. EXPECT MOSTLY VFR CONDITIONS AFTER 14Z TUESDAY BEFORE SHOWER/THUNDERSTORM ACTIVITY BEGINS AGAIN AFTER 18Z TUESDAY, LASTING INTO WEDNESDAY. HIGH PRESSURE WITH DRIER AIR WILL BRING AN END TO THE PRECIPITATION THREAT FOR THURSDAY AND FRIDAY. && .MARINE... GENERALLY TRANQUIL CONDITIONS ARE FORECAST TO CONTINUE INTO WEDNESDAY WITH THE EXCEPTION OF ANY TSTMS THAT MIGHT DEVELOP THIS AFTERNOON/EVENING AND AGAIN TUESDAY INTO WEDNESDAY. THE ANTICIPATED NE ONSHORE FLOW THAT IS EXPECTED TO BEGIN TUESDAY MAY PUSH SEAS TO NEAR SMALL CRAFT ADVISORY CRITERIA WEDNESDAY INTO THURSDAY NIGHT. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...NONE.
