Special Marine Warning 67, NWS Philadelphia/Mount Holly

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
445 PM EDT FRI JUL 1 2005

.SHORT TERM/LONG TERM...
LAPS ANALYSIS SHOWS CAPES(AWAY FROM THE COAST) IN EXCESS OF 2K J/KG.
THIS IS ON PAR WITH WHAT MODELS SUGGESTED YDY AND GREATER THAN WHAT
BUFKIT SUGGESTED THIS MORNING(12Z RUN).

AFTER CONVECTIVE TEMPS WERE MET A SHORT TIME AGO, IT DIDNT TAKE
LONG FOR THINGS TO FIRE UP. THE THUNDERSTORMS ARE MOVING ALONG,
COMPARED TO WHAT TOOK PLACE OVER THE PAST WEEK OR SO. ALTHOUGH FLASH
FLOODING CANT BE RULED OUT IN THIS 70+ DEWPOINT AIRMASS, THEIR
MOVEMENT SHOULD HELP.

THE ACTUAL COLD FRONT WILL MOVE THROUGH THE CWA LATER THIS EVENING
ACROSS OUR NORTHWESTERN ZONES AND PUSH SOUTH OVERNIGHT. INSTABILITY,
ALBEIT WEAKER, REMAINS IN TACT UNTIL FROPA. AFTER MORE NUMEROUS
THUNDERSTORMS THIS EVENING, AN ISOLATED ONE(OR SHOWER) CANT BE
RULED OUT DURING THE OVERNIGHT HOURS. THINGS ARE EXPECTED TO QUIET
DOWN BEFORE SUNRISE ON SATURDAY.

A SOUTHEAST FLOW DEVELOPED EARLIER THIS AFTERNOON. THIS HAS PUSHED
AREAS OF LOW CLOUDS AND FOG INTO OUR NEARSHORE WATERS AND ADJACENT
LAND-BASED ZONES.

LITTLE WAS CHANGED THIS WEEKEND THROUGH THE EARLY PART OF THE WEEK
AS ZONAL MIDLEVEL FLOW WILL DOMINATE. WELL MAINTAIN THE NEXT THREAT
OF PRECIPITATION DURING THE MIDWEEK TIME FRAME.

WILL KEEP SHORT, SVRS ARE FLYING.

&&

.AVIATION...
AT 19Z THERE ARE STILL SOME MVFR VISIBILITIES IN HAZE AROUND THE
AREA, OTHERWISE THE STRATUS HAS THINNED AND RAISED TO CUMULUS, WITH
HIGHER LAYERS MOVING OVER THE AREA ASSOCIATED WITH UPSTREAM
CONVECTION. THERE ARE A COUPLE OF THUNDERSTORM CELLS OVER DELAWARE,
OTHERWISE WE ANTICIPATE THAT AS THE LOW LEVEL FORCING IS ENHANCED,
ADDITIONAL CONVECTION WILL INITIATE, AND WE CONTINUE TO ADDRESS THIS
WITH A TEMPO GROUP FOR IFR CONDITIONS IN THUNDERSTORMS. THE TIME
FRAME FOR THIS IS THOUGHT TO BE FROM 20Z TO 02Z, WITH IMPROVING
CONDITIONS FOLLOWING IN THE OVERNIGHT PERIOD. WITH SOME WIND AND MID
LEVEL CLOUDINESS PREVENTING GREAT RADIATION, ALONG WITH DRIER AIR
MOVING IN, WE DID NOT ADD IN ANY LOWER VISIBILITIES FROM 06Z TO 12Z.
THEN, ANY MID LEVEL CLOUDS ARE FORECAST TO EXIT AROUND OR SHORTLY
AFTER SUNRISE, WITH ONLY SOME SCATTERED HIGH CLOUDS THEREAFTER.

&&

.MARINE...
CONDITIONS ARE FORECAST TO REMAIN BELOW SMALL CRAFT CRITERIA THROUGH
WEDNESDAY. WINDS AND WAVES WILL BE HIGHER NEAR ANY THUNDERSTORMS
EARLY TONIGHT, AND THIS STATEMENT WILL BE ADDED TO THE TONIGHT
PORTION OF THE FORECAST.
