...DENSE FOG ADVISORY IS CANCELLED...

THE NATIONAL WEATHER SERVICE IN MOUNT HOLLY HAS CANCELLED THE
DENSE FOG ADVISORY. SOME LOCALIZED SPOTS OVER SOUTHERN NEW JERSEY,
DELAWARE AND THE NORTHERN MARYLAND EASTERN SHORE WERE REPORTING
VISIBILITIES OF AROUND ONE MILE THIS MORNING, AND THERE WERE SOME
AREAS OF DRIZZLE AS WELL, BUT WIDESPREAD DENSE FOG IS NO LONGER
CONSIDERED A THREAT. 

PEOPLE DRIVING THIS MORNING STILL SHOULD BE CAREFUL IN THE EVENT
THAT THEY ENCOUNTER PATCHY DENSE FOG OR DRIZZLE. USE LOW-BEAM
LIGHTS, DRIVE SLOWLY AND LEAVE PLENTY OF DISTANCE BETWEEN YOURSELF
AND OTHERS.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
402 PM EDT WED MAY 9 2007

.SYNOPSIS...
SURFACE HIGH PRESSURE WILL BREAK DOWN TONIGHT AND TOMORROW. THIS
WILL ALLOW A COLD FRONT TO PUSH THROUGH THE REGION LATE ON FRIDAY.
HIGH PRESSURE WILL STRENGTHEN ACROSS THE AREA ON SATURDAY AND
PERSIST THROUGH MONDAY. ANOTHER FRONTAL SYSTEM IS THEN EXPECTED TO
ARRIVE TUESDAY OR WEDNESDAY.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
YOU CAN FEEL THE HUMIDITY IN THE AIR THIS AFTERNOON WITH DEWPOINTS
IN THE UPPER 50S TO MIDDLE 60S. WHILE DEWPOINTS ARE UP ABOUT 10 TO
15 DEGREES ACROSS THE COASTAL PLAIN, THEYRE UP A WHOPPING 25 TO 30
DEGREES ACROSS THE INTERIOR. 12Z BUFKIT SOUNDINGS SUPPLIED THE
REGION WITH A GOOD AMOUNT OF INSTABILITY. CAPES FOR THIS AFTERNOON
ACROSS THE INTERIOR WERE IN EXCESS OF 1000 J/KG WHILE LIS DROPPED
TO -4 IN SOME CASES. THE MISSING SYNOPTIC INGREDIENT WAS A TRIGGER.
BUT AS THE AFTERNOON PROGRESSED, BOTH A SEABREEZE AND BAYBREEZE
DEVELOPED AND IN THE LAST HOUR OR TWO, ISOLATED SHOWERS HAVE
DEVELOPED. WELL CARRY 20 POPS INTO THE EARLY EVENING BECAUSE OF
THIS ACROSS THE CENTRAL AND SOUTHERN ZONES, EXCLUDING THE COASTAL
STRIP.

LATER TONIGHT, ANOTHER ROUND OF FOG AND LOW CLOUDS ARE EXPECTED. THE
FOG IS EXPECTED TO BECOME DENSE IN SPOTS AND COULD NECESSITATE A
DENSE FOG ADVISORY LATER THIS EVENING OR OVERNIGHT.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY/...
THE MENTION OF FOG AND LOW CLOUDS WERE RETAINED IN THE EARLY MORNING
HOURS ON THURSDAY. SKIES SHOULD BECOME PARTLY SUNNY THEREAFTER.
WELL HIT POPS A LITTLE HARDER ACROSS THE WESTERN ZONES WITH THE
APPROACH OF A SURFACE TROF. WHILE I CANT RULE OUT AN ISOLATED
STRONG THUNDERSTORM, THE BEST INGREDIENTS FOR ANY INTENSE
THUNDERSTORMS ON A LARGE SCALE LEVEL SHOULD STAY TO OUR WEST THROUGH
00Z FRI. EITHER CHANCE OR SLIGHT CHANCE POPS WERE MAINTAINED ON
THURSDAY NIGHT WITH THE ADVANCE OF THE SURFACE TROF. THE ACTUAL
FRONTAL PASSAGE WILL BE LATE ON FRIDAY. THE HIGHEST POPS AND THE
GREATEST LIKELIHOOD FOR THUNDERSTORMS ON FRIDAY APPEARS TO BE ACROSS
THE SOUTHERN ZONES IN THE AFTERNOON.

TEMPERATURES WILL RUN ABOVE NORMAL THROUGH THE PERIOD.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
THE FORECAST PERIOD BEGINS WITH A COLD FRONT WORKING THROUGH THE
SOUTHERN PORTION OF THE CWA. HIGH PRESSURE WILL BEGIN TO OOZE IN
FROM THE NORTHWEST ON SATURDAY, CENTER ITSELF OVERHEAD ON SUNDAY
NIGHT, AND PUSH OFF THE COAST ON MONDAY.

THE MID-LEVEL FLOW GOES PRETTY MUCH ZONAL BY TUESDAY. WITH THE
NEARLY ZONAL FLOW, A SURFACE COLD FRONT WILL TAKE ITS SWEET TIME AS
IT CROSSES THE REGION TUESDAY NIGHT INTO WEDNESDAY.

USING A COMBINATION OF THE ECMWF/NCEP ENSEMBLE MEAN, ILL RESTRICT
ANY PRECIPITATION CHANCES TO OUR SOUTHERN ZONES ON FRIDAY NIGHT AND
INTO SATURDAY WITH THE DEPARTING COLD FRONT. MOTHERS DAY CONTINUES
TO LOOK DRY WITH HIGH PRESSURE SHIFTING FROM THE GREAT LAKES TO THE
MID-ATLANTIC REGION DURING THE COURSE OF THE DAY. WITH REALLY NO
CHANGE FROM YESTERDAYS THINKING, ILL KEEP THE POPS IN PLACE MONDAY
NIGHT INTO TUESDAY. FOR WEDNESDAY, THE NEW DAY 7, ILL KEEP THE POPS
GOING WITH THE SLOW MOVING SURFACE FRONT EXPECTED.

AS FOR TEMPERATURES, THEYLL REMAIN ABOUT NORMAL OR RISE TO ABOVE
NORMAL STATUS THROUGH THE PERIOD. SUNDAY COULD POTENTIALLY BE THE
COOLEST DAY OF THE EXTENDED, IF THINGS PAN OUT, ESPECIALLY ALONG THE
COAST AND COASTAL PLAIN WHERE ONSHORE BREEZES ARE FORECAST.

&&

.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
EARLY AFTN DWPTS ARE AT OR ABOVE ALL GUIDANCE MIN TEMPS THE SFC
FLOW MAINTAINS AN ONSHORE TRAJECTORY FOR AT LEAST THE SIX
SOUTHEASTERNMOST TAF SITES, AND BUFKIT SOUNDINGS ALL SITES ARE
DEVELOPING A SATURATED SURFACE LAYER. WE THEREFORE ARE FORECASTING A
REPEAT OF LAST NIGHTS LOW CIGS AND VSBYS, WITH THE ADVENT OF THEM
COMING A BIT EARLIER AND THE EXTENT OF THEM REACHING FURTHER NW THAN
LAST NIGHT. WE FORECAST IMPROVING CONDITIONS BY LATE MORNING PER
CLIMATOLOGY AND BUFKIT.

IN THE LONGER TERM, A SLOW MOVING BOUNDARY MAY TRIGGER SOME
CONVECTION ANY TIME FROM THURSDAY NIGHT TO FRIDAY NIGHT. WHETHER OR
NOT THURSDAY NIGHT IS ANOTHER NIGHT OF LOW CIGS AND FOG WOULD DEPEND
UPON WHETHER WE MAINTAIN THE ONSHORE FLOW AND WHETHER MID CLOUDS
COME IN AND CUT OFF A DROP IN TEMPS TO THE DWPTS. AS OF RIGHT NOW,
MORE FOG AND STRATUS FOR THURSDAY NIGHT CANT BE RULED OUT.

&&

.MARINE...
SEAS AT 44025 ARE DOWN TO 3.9 FT IN 9 SEC SWELLS. AT AVALON, SEAS
ARE 3.6 FT IN 9 SEC SWELLS. AT 44025, SEAS ARE 5.6 FT IN 9 SEC
SWELLS, WHICH PUTS THEM ABOUT 1.5 FT BELOW WAVE WATCH. WE WILL USE
ALL THIS TO DROP THE SCA FOR WATERS FROM LITTLE EGG INLET TO CAPE
HENLOPEN, AND LET IT CONTINUE UNTIL 00Z FOR WATERS FROM CAPE
HENLOPEN TO FENWICK ISLAND. SUSTAINED WINDS AND GUSTS THROUGH THE
PERIOD ARE FORECAST TO REMAIN BELOW SCA CRITERIA.

MORE WIDESPREAD FOG IS EXPECTED TONIGHT, AS THE WATER TEMPS ARE IN
THE 50S AND THE DWPTS COMING ONSHORE ARE AROUND 60. FOG EXPECTED TO
BECOME MORE PATCHY DURING COURSE OF THE DAY, BUT MAY REDEVELOP THU
NIGHT.
