AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
842 PM EST FRI FEB 22 2008

.SYNOPSIS...
LOW PRESSURE OFF THE MID ATLANTIC COAST THIS EVENING WILL
INTENSIFY AS IT MOVES NORTHEAST OVERNIGHT. ANOTHER LOW OVER THE
OHIO RIVER VALLEY WILL MIGRATE EAST TO THE VIRGINIA COAST BY
SATURDAY AFTERNOON BEFORE MOVING OUT TO SEA SATURDAY NIGHT. HIGH
PRESSURE IS THEN EXPECTED TO BUILD OVER THE REGION SUNDAY AND
MONDAY. A COLD FRONT WILL MOVE FROM WEST TO EAST ACROSS THE REGION
LATE TUESDAY AFTERNOON AND NIGHT. ANOTHER HIGH THEN BUILDS IN FROM
THE WEST BEGINNING WEDNESDAY.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
SURFACE TEMPERATURES ARE JUST ABOVE FREEZING FROM SOUTHEAST
PENNSYLVANIA AND SOUTHERN NEW JERSEY AND POINTS SOUTH. WITH THIS
IN MIND, AND GIVEN THE FACT THAT RECENT RADAR IMAGERY AND SFC OBS
INDICATE A BACK EDGE TO THE CURRENT ROUND OF PRECIPITATION IN
EASTERN PA...HAVE DECIDED TO DROP THE ADVISORY WHICH WAS
POSITIONED SOUTH AND EAST OF THE I-95 CORRIDOR. ANOTHER ROUND OF
LIGHT PRECIPITATION COULD BE IN STORE FOR THIS SAME REGION
OVERNIGHT, BUT TEMPERATURES MAY BE COLD ENOUGH AT THE POINT IN
TIME FOR SOME OF THE PRECIPITATION TO FALL AS SNOW OR A SNOW/RAIN
MIX. THE WARNINGS JUST TO THE NORTH OF THE NOW CANCELLED ADVISORY
AREA WILL REMAIN AS IS FOR RIGHT NOW, MAINLY BECAUSE OF FREEZING
RAIN IN THE SOUTHERN LEHIGH VALLEY AND CENTRAL NEW JERSEY...AND
SNOW FURTHER NORTH. HOWEVER, THESE WARNINGS WILL BE REVISITED OVER
THE NEW FEW HOURS, AND IF NEED BE, WILL ALSO BE DROPPED...OR DOWNGRADED
TO ADVISORIES.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH SUNDAY/...
RESIDUAL SNOW UP NORTH AND RAIN SOUTH WITH A MIXTURE IN BETWEEN ON
SATURDAY WITH A MIXTURE IN BETWEEN AS THE LOW FROM THE OHIO VALLEY
MOVES EAST. NO ADDITIONAL ACCUMULATIONS EXPECTED. CLEARING SKIES
EXPECTED SATURDAY NIGHT, AND CLEAR SKIES EXPECTED AGAIN ON SUNDAY
AS HIGH BUILDS OVER THE REGION.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
HIGH PRESSURE WILL PROVIDE FAIR WEATHER SUNDAY NIGHT INTO MONDAY
NIGHT. MOISTURE RUNNING AHEAD OF LOW PRESSURE MOVING IN FROM THE
WEST WILL CAUSE INCREASING CLOUDINESS MONDAY NIGHT WITH THE CHANCE
FOR SNOW SHOWERS NORTH AND RAIN OR SNOW SHOWERS SOUTH. THE LOW IS
EXPECTED TO TRACK NORTHEAST INTO NEW YORK STATE TUESDAY. THIS WILL
ALLOW MILD AIR TO OVERSPREAD THE FORECAST AREA AND BRING RAIN TO
MOST AREAS TUESDAY. THE RAIN MAY BE MIXED WITH SNOW NORTH,
ESPECIALLY EARLY IN THE DAY. THE COLD FRONT ASSOCIATED WITH THE
LOW WILL CROSS THE AREA LATE TUESDAY. THIS WILL BRING COLDER AIR
BACK INTO THE REGION ALLOWING THE PRECIPITATION TO CHANGE BACK
OVER TO SNOW IN MOST AREAS BEFORE ENDING WEDNESDAY MORNING. AS
HIGH PRESSURE PUSHES IN FROM THE WEST AND THE LOW EXISTS TO THE
NORTHEAST, A COLD NORTHWEST FLOW WILL SET IN AND BRING A RETURN TO
FAIR AND COLD WEATHER WEDNESDAY NIGHT INTO FRIDAY.

&&

.AVIATION /02Z SATURDAY THROUGH WEDNESDAY/...
IT IS A TERRIBLE DAY OVER A GOOD PART OF THE MID ATLANTIC AND
NORTHEAST PARTS OF THE COUNTRY. LOW IFR IS PREVALENT WITH SOME
SPOTTY FREEZING RAIN OR DRIZZLE NORTH OF PHILADELPHIA AND RAIN
SOUTH. YOU TALK ABOUT A SUCKER HOLE, THE VISIBLE SATELLITE IS
SHOWING ONE OVER THE WEST VIRGINIA PAN HANDLE WHERE THE LOWEST CIGS
ARE 2,500 FT WITH BINOVC. WE WERE WARNED ABOUT THIS WHEN LEARNING TO
FLY AND THIS IS A GOOD EXAMPLE OF BEING CAREFUL NOT TO THINK THESE
CONDITIONS PREVAIL.

ANYWAY, THE PRECIPITATION WILL COME TO AN END AS THE LOW MOVES ALONG
THE COAST. THE ISOBARS WILL TIGHTEN AND THE WINDS SWITCH TO THE
NORTH WHICH WILL BRING IN SOME MIXED WINTER TYPE PRECIPITATION, BUT
NOT HEAVY.

THE VWP(VAD WIND PROFILE FROM 88D)SHOWS THE TOP OF THE NEAR SURFACE
BASED DECK TO AROUND 9,000 FT WITH AN ALTO CU DECK THAT BEGINS
AROUND 14,000 FT UP THROUGH 22,000 FT.

WE CAN EXPECT TO REMAIN IN LOW CLOUDS THROUGH SATURDAY EVENING,
ALTHOUGH THERE WILL BE SOME MVFR/VFR BRIEF PERIODS. HIGH PRESSURE
BUILDS OVER THE REGION ON SUNDAY AND LAST THROUGH TUESDAY NIGHT.

ANOTHER INLAND TRACKING LOW WILL BRING A WET PERIOD OF MILD WEATHER
TUESDAY INTO TUESDAY NIGHT WITH A RETURN TO COOLER GUSTY WINDS ON
WEDNESDAY.

&&

.MARINE...
WEAK LOW OVER THE CAROLINAS WILL CONTINUE NORTH AND PARALLEL NJ/DE
COASTS THIS EVENING. THE GRADIENT WILL TIGHTEN ON THE EASTERN SIDE
OF THE LOW AND REMAIN RATHER WEAK ON THE MAINLAND SIDE. AS A RESULT
NOT EXPECTING MUCH WIND BUT THE SEAS BROUGHT ON BY THE OPEN WATER
FETCH MAY HOVER AROUND 4 FT AND ON OCCASION REACH 5 FT.

THE LOW WILL MOVE WELL OF OUT THE PICTURE BY THIS TIME TOMORROW AS
HIGH PRESSURE BEGINS TO BUILD IN FROM THE WEST AND THEN MOVE OFF THE
COAST ON TUESDAY. MEANWHILE, A VERY WET LOW PRESSURE WILL FORM OVER
THE OHIO VALLEY TUESDAY THEN TRACK INTO NEW YORK STATE ON WEDNESDAY
AND INTO NORTHERN NEW ENGLAND NEW ENGLAND WEDNESDAY.

THIS LOW WILL HAVE A STRONG GRADIENT AHEAD OF IT, WITH WINDS FROM
THE SOUTH ON TUESDAY AND FROM THE NORTHWEST ON WEDNESDAY WITH COLD
AIR POURING DOWN ACROSS THE REGION. THE STRONG OFFSHORE WIND WILL
CONTINUE INTO WEDNESDAY NIGHT THEN THE WINDS SLACKEN OFF ON
THURSDAY.

SMALL CRAFT ADVISORIES WILL PROBABLY BE NEEDED TUESDAY INTO
THURSDAY.
