AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
343 AM EDT THU SEP 27 2007

.SYNOPSIS...
A COLD FRONT FROM NORTHERN NEW ENGLAND DOWN THROUGH THE ST. LAWRENCE
AND OHIO RIVER VALLEYS WILL SLOWLY MAKE ITS WAY ACROSS OUR AREA LATE
TODAY INTO EARLY FRIDAY. BEHIND THE FRONT, HIGH PRESSURE WILL REMAIN
IN CONTROL OF THE WEATHER THROUGH THE WEEKEND AND INTO THE MIDDLE OF
NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
THE SHOWERS AND THUNDERSTORMS THAT WERE AFFECTING WESTERN PORTIONS
OF THE FORECAST AREA LAST EVENING DIED OUT AROUND MIDNIGHT. WILL
CARRY SLIGHT CHANCE POPS FOR THIS MORNING IN OUR NORTHWEST ZONES
ONLY FOR THE POSSIBILITY OF A POP UP SHOWER. IT NOW APPEARS AS IF
MOST OF THE SHOWER/THUNDERSTORM ACTIVITY WILL OCCUR LATER TODAY
AND TONIGHT AS THE FRONTAL ZONE MOVES ACROSS. THE FORECAST AREA
REMAINS SANDWICHED BETWEEN THE FRONTAL ZONE TO OUR NORTHWEST AND
LOW PRESSURE ALONG THE SOUTH ATLANTIC COAST. NOT MUCH IN THE WAY OF
CLOUDS OVER A GOOD PORTION OF THE FORECAST AREA THIS MORNING, SO,
UNTIL SHORTLY AFTER SUNRISE, PATCHY FOG WILL ONCE AGAIN BE
ENCOUNTERED. WITH TEMPERATURES STARTING OUT QUITE MILD AND A GOOD
DEAL OF SUNSHINE EXPECTED THIS MORNING, HIGH TEMPERATURES TODAY
SHOULD EASILY CLIMB WELL INTO THE 80S. CLOUDINESS SHOULD INCREASE
THIS AFTERNOON AND KEEP READINGS A FEW DEGREES BELOW YESTERDAYS
NEAR RECORD HIGHS. IF THE CLOUDINESS DOES NOT MOVE IN AS EXPECTED,
HIGH TEMPERATURES COULD BE VERY CLOSE TO YESTERDAYS READINGS.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY/...
THE MOST LIKELY TIME FOR SHOWERS AND THUNDERSTORMS WILL BE TONIGHT
AS THE FRONT MOVES ACROSS. POPS WILL BE IN THE LIKELY RANGE NORTH
AND CHANCE RANGE SOUTH. THE FRONT WILL BE MOVING OFF TO THE EAST
BY DAYBREAK FRIDAY. WILL CARRY SLIGHT CHANCE POPS IN THE MORNING
FOR THE POSSIBILITY OF A LINGERING SHOWER. CLEARING WILL SET IN
BY AFTERNOON ALONG WITH BREEZY NORTHWEST WINDS AND MUCH DRIER AIR.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
HIGH PRESSURE IS FORECAST TO MOVE INTO THE AREA OVER THE WEEKEND AND
REMAIN THROUGH THE MIDDLE OF NEXT WEEK. WITH THE HIGH PRESSURE IN
CONTROL, DRY WEATHER AND SLIGHTLY ABOVE NORMAL TEMPERATURES ARE
EXPECTED FOR THE DURATION OF THE EXTENDED PERIOD.

&&

.AVIATION /07Z TODAY THROUGH MONDAY NIGHT/...
THERE WILL BE SOME SCATTERED MID AND HIGH CLOUDS OVER THE REGION
EARLY THIS MORNING, BUT THESE CLOUDS SHOULD NOT BE ENOUGH TO KEEP
PATCHY FOG FROM FORMING. ALTHOUGH DENSE FOG IS NOT EXPECTED, VSBY IN
EARLY MORNING FOG WILL GENERALLY BE 3-5 MI, BUT SOME AREAS, MAINLY
IN SOUTHERN NEW JERSEY WILL SEE VSBY AROUND 1 MI. ALSO, RDG COULD
SEE 1 MI VSBY SINCE THEY GOT SOME RAIN LAST EVENING AND THAT SHOULD
ALSO HELP FORM PATCHY FOG THERE.

AS THE DAY PROGRESSES, ANY PATCHY FOG WILL DISSIPATE BY LATE MORNING
AND VFR CONDITIONS SHOULD BECOME WIDESPREAD. A COLD FRONT FROM THE
GREAT LAKES WILL GET CLOSE ENOUGH THAT SCATTERED SHOWERS OR TSTMS
ARE POSSIBLE IN THE AFTN AT ABE/RDG. TONIGHT, THE CONVECTION WILL
CONTINUE TO MOVE SOUTH AND EAST AFFECTING THE REST OF THE TAF SITES
TONIGHT. ONCE SHOWERS AND TSTMS SPREAD INTO AN AREA, MVFR CONDITIONS
SHOULD DEVELOP WITH CIG 1-3 THSD FT AND VSBY 3-5 MI, BUT IN ANY
HEAVIER SHOWERS OR TSTMS, IFR CONDITIONS ARE POSSIBLE.

LONGER RANGE...THE FRONT SHOULD MOVE THROUGH EARLY FRIDAY MORNING
WITH A RETURN TO VFR CONDITIONS DURING THE DAY. GUSTY WINDS ARE
EXPECTED FRIDAY AFTERNOON WITH WIND GUSTS UP TO 25 KT EXPECTED.

&&

.MARINE...
SCA HAVE BEEN ISSUED FOR FRIDAY AFTERNOON AND NIGHT FOR GUSTY NW
WINDS.

A COLD FRONT FROM THE GREAT LAKES WILL DROP SOUTHEAST CROSSING THE
FORECAST AREA EARLY FRIDAY MORNING. SHOWERS AND TSTMS ASSOCIATED
WITH THE FRONT WILL AFFECT THE REGION TONIGHT AND SOME SHOWERS COULD
LINGER INTO FRIDAY MORNING. WINDS AND SEAS SHOULD REMAIN BELOW SCA
CRITERIA INTO FRIDAY MORNING. AS COOLER AIR MOVES IN FROM THE NW ON
FRIDAY, WINDS WILL INCREASE AND BECOME GUSTY ON FRIDAY, WITH WIND
GUSTS OF 25 KT EXPECTED IN THE AFTN. THE STRONGEST WIND GUSTS WILL
BE OVER DELAWARE BAY AND NEAR THE COAST. FRIDAY NIGHT, GUSTY WINDS
SHOULD BE WIDESPREAD OVER THE REGIONAL WATERS. ON SATURDAY, THE
GRADIENT WEAKENS AND WINDS SHOULD DECREASE. TRANQUIL CONDITIONS ARE
THEN EXPECTED FOR THE WEEKEND AND EARLY NEXT WEEK.

&&

.CLIMATE...
TEMPERATURES ARE FORECAST TO REMAIN ABOVE NORMAL FOR MUCH OF THE
FORECAST PERIOD, EVEN AFTER THE FRONT MOVES OFF TO THE EAST FRIDAY.
