Special Marine Warning 22, NWS Philadelphia/Mount Holly

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
910 PM EDT THU JUL 5 2007

.SYNOPSIS...
THE COLD FRONT CURRENTLY OVER THE EASTERN GREAT LAKES WILL CROSS
THE AREA OVERNIGHT TONIGHT AND INTO FRIDAY MORNING. WEAK HIGH
PRESSURE WILL BUILD IN OVER THE WEEKEND. ANOTHER FRONTAL BOUNDARY
IS EXPECTED TO STALL NEAR THE AREA NEXT TUESDAY, THEN RETURN NORTH
AS A WARM FRONT BEFORE ANOTHER COLD FRONT MOVES THROUGH THE AREA
BY THE END OF THE WEEK.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
SOME SHOWERS AND THUNDERSTORMS ARE STILL LINGERING ACROSS THE AREA
BUT OVERALL INTENSITY AND AREAL COVERAGE HAS DECREASED AS THE REGION
HAS STABILIZED OVERALL.  CAN NOT RULE OUT SHOWERS AND STORMS
ESPECIALLY ACROSS NORTHERN AND WESTERN AREAS.  THERE ARE SOME
ADDITIONAL SHOWERS AND STORMS IN CENTRAL AND WESTERN PA AND IT
REMAINS TO BE SEEN IF THEY WILL HOLD TOGETHER AND MAKE IT TO THE
REGION OVERNIGHT. NEVERTHELESS,  WILL MAKE SOME MINOR ADJUSTMENTS TO
POPS BASED ON CURRENT RADAR TRENDS.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/...
WE MAINTAIN A CHANCE OF SHOWERS AND THUNDERSTORMS THROUGH LATE
MORNING/EARLY AFTERNOON AS THE FRONT WILL BE SLOW TO MOVE OFFSHORE
AND THE MID-LEVEL VORT MAX AND COLD POOL IS FORECAST TO CROSS
OVERHEAD DURING THE MORNING HOURS. ONCE IT PASSES BY MIDDAY, THE
SHOWER/THUNDERSTORM ACTIVITY SHOULD DIMINISH QUICKLY. SKIES ARE
EXPECTED TO BEGIN TO CLEAR OUT BY LATE AFTERNOON/EARLY EVENING,
LEAVING A FAIRLY NICE NIGHT.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
FAIR WEATHER WILL PREVAIL ACROSS THE FORECAST AREA FOR THE WEEKEND
AS WEAK HIGH PRESSURE WILL BUILD JUST SOUTH OF THE REGION THROUGH
MONDAY. A FRONTAL BOUNDARY WILL APPROACH THE AREA OVERNIGHT MONDAY
AND INTO TUESDAY MORNING, THEN STALL JUST SOUTH OF THE AREA BEFORE
MOVING BACK NORTHWARD AS A WARM FRONT WEDNESDAY. FINALLY A COLD
FRONT IS EXPECTED TO CROSS OUR AREA THURSDAY INTO FRIDAY. THIS IS
AT THE END OF THE FORECAST PERIOD, SO DETERMINING WHERE AND HOW
MUCH RAIN WILL OCCUR IS DIFFICULT TO DETERMINE. WITH THIS SAID, WE
HAVE A SMALL CHANCE OF SHOWERS AND THUNDERSTORMS EACH DAY FROM
TUESDAY ONWARD. THE ONE THING THAT IS NEARLY FOR SURE IS THE WARM
UP THAT WILL OCCUR OVER THE WEEKEND INTO EARLY NEXT WEEK.
TEMPERATURES ARE FORECAST TO RETURN TO THE LOWER 90S BY SUNDAY
AND LAST THROUGH AT LEAST TUESDAY. ALONG WITH THE RISING
TEMPERATURES, THE HUMIDITIES ARE FORECAST TO RISE AS WELL AS
DEW-POINTS ARE EXPECTED TO BE IN THE UPPER 60S TO NEAR 70. THE
COMBINATION OF INCREASING HEAT AND HUMIDITY WILL LEAD TO HIGH HEAT
INDEX VALUES, WHICH MAY REQUIRE HEAT ADVISORIES OR EXCESSIVE HEAT
WARNINGS IN FUTURE FORECASTS.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
BROAD SOUTHWEST FLOW CONTINUES AHEAD OF AN APPROACHING UPPER LVL
SHORT WAVE. THE SHORT WAVE WILL SWING THROUGH LATE TONIGHT
TRIGGERING SHOWERS AND TSTMS ACROSS THE REGION. SKIES ARE VFR AND
LIKELY TO REMAIN THAT EXCEPT WHEN TSTMS MOVE THROUGH. SCATTERED
CONVECTION FIRING UP TO OUR WEST AND WIDESPREAD ENOUGH TO ENCOURAGE
PILOTS TO REMAIN OVER EASTERN PA AND EAST. SOME PRETTY STRONG CELLS
HAVE DEVELOPED AND THERE IS A SEVERE THUNDERSTORM WATCH IN EFFECT
ACROSS THE POCONOS AND THE NORTHERN HALF OF PENNSYLVANIA. REMAINDER
OF THE AREA REMAINS IN SLIGHT RISK. THE UPPER TROUGH AND
RELATED SURFACE FRONT DONT PUSH THROUGH UNTIL FRIDAY. HIGH
PRESSURE WILL BUILD OVER THE WATERS OVER THE WEEKEND INTO MONDAY
ACCOMPANIED BY GOOD VFR WEATHER. A BACK-DOOR FRONT WILL APPROACH
MONDAY NIGHT INTO TUESDAY MORNING AND REMAINS PRETTY CLOSE TO THE
AREA WITH SHOWERS FORMING ALONG IT INTO WEDNESDAY.

VSBL SATELLITE SHOWING SKIES CLEARING AND WILL ONLY BE A SHORT
MATTER OF TIME BEFORE TSTMS BEGINNING POPPING FARTHER EAST.

&&

.MARINE...
SMALL CRAFT ADVISORY LOWERED ON THE LOWER DELAWARE BAY AND ON THE
COAST. SEAS AT 44009 5 FT AT 6 SECONDS AND WINDS SOUTHWEST GUSTING
TO 21 KTS. SEAS NEARSHORE HAVE COME DOWN TO 3.5 FT AT AVALON. WIND
GRADIENT RELAXES THIS EVENING WHICH WILL CONTINUE TO LOWER THE WAVE
HEIGHTS.

MAIN PROBLEM TONIGHT WILL BE THE DEVELOPING TSTMS. THEY HAVE FORMED
OVER LAND BUT HOW FAR EAST INTO THE MORE STABLE AIR WILL THEY
REACH. ILL PLAY UP THE POTENTIAL FOR A STRONG GUSTY STORM AT
LEAST FOR THIS EVENING.

THE FRONT WILL REACH TO THE COAST AFTER MIDNIGHT THEN STALL WAITING
FOR THE FINAL PUSH WHICH WILL COME FROM ALOFT. THE TROUGH SHOULD
CLEAR THE NJ COAST SOMETIME IN THE LATE MORNING OR EARLY AFTERNOON
ON FRIDAY. A HIGH PRESSURE WILL BUILD OVER THE WATERS LATE FRIDAY
INTO MONDAY WITH FAIRLY NICE WEATHER FOR THOSE WHO EXTENDED THEIR
4TH OF JULY HOLIDAY.

A BACK-DOOR COLD FRONT WILL APPROACH FROM THE NORTH LATE MONDAY
INTO TUESDAY AND BRING MORE SHOWERS. OUTSIDE OF THIS AFTERNOON,
THE WAVE WATCH MODEL KEEPS THE SEAS UNDER 5 FT THROUGH THE 13TH.
