AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
630 PM EST WED JAN 2 2008

.SYNOPSIS...
COLD BLUSTERY NORTHWEST WINDS WILL CONTINUE THROUGH TONIGHT AND MUCH
OF THURSDAY AS ARCTIC AIR SURGES INTO THE REGION. HIGH PRESSURE
BUILDING IN FROM THE PLAINS STATES WILL REACH OUR AREA FRIDAY AND
MOVE SLOWLY OFF TO THE EAST OVER THE WEEKEND.

&&

.NEAR TERM /THROUGH TONIGHT/...
THE COLD ARCTIC AIR SURGING INTO OUR AREA HAS ALREADY BROUGHT
CLEARING TO MOST OF THE REGION. SOME CLOUDINESS IS LINGERING
ALONG COASTAL SECTIONS BUT WILL MOVE OFFSHORE DURING THE LATE
AFTERNOON AND EVENING HOURS. SKIES WILL BE MOSTLY CLEAR OVERNIGHT
WITH JUST A SPATTERING OF CLOUDS OVER THE NORTHERN MOUNTAINS.
NORTHWEST WINDS WILL CONTINUE THROUGH THE NIGHT. WIND CHILLS
WILL DROP INTO THE SINGLE DIGITS OVER MOST OF THE FORECAST AREA,
WITH BELOW ZERO READINGS IN THE NORTH, POSSIBLY DROPPING AS LOW
AS 10 BELOW IN THE POCONOS BY DAYBREAK THURSDAY.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
AS THE HIGH PRESSURE SYSTEM NUDGES IN FROM THE WEST, SKIES WILL
REMAIN MOSTLY CLEAR THROUGH THURSDAY NIGHT, ALTHOUGH THERE WILL
BE A FEW CLOUDS IN THE NORTH. NORTHWEST WINDS WILL CONTINUE
THURSDAY. COMBINING THE WINDS WITH AFTERNOON TEMPERATURES CLIMBING
INTO THE TEENS AND 20S, WILL GIVE WIND CHILLS IN SINGLE DIGITS
NORTH AND IN THE TEENS SOUTH. IN THE POCONOS, WIND CHILLS WILL
STRUGGLE TO REACH ZERO.

THE WINDS WILL DROP OFF THURSDAY NIGHT AS THE HIGH PRESSURE SYSTEM
APPROACHES THE MID ATLANTIC REGION. WITH MOSTLY CLEAR SKIES AND
LIGHT WINDS, TEMPERATURES WILL DROP TO THE 5 TO 15 DEGREE RANGE FOR
MOST OF OUR AREA.

THE HIGH PRESSURE SYSTEM WILL INCH ITS WAY SLOWLY EAST REACHING
THE ATLANTIC COAST LATE FRIDAY NIGHT. TEMPERATURES WILL BEGIN TO
MODERATE SLIGHTLY FRIDAY UNDER SUNNY TO PARTLY SUNNY SKIES WITH
READINGS CLIMBING INTO THE 30S AND LOW 40S. FRIDAY NIGHT WILL SEE
MOSTLY CLEAR SKIES WITH GOOD RADIATING CONDITIONS ONCE AGAIN.
TEMPERATURES WILL BE COLD BUT NOT QUITE AS COLD AS THURSDAY NIGHT.
READINGS WILL RANGE FROM AROUND 10 ABOVE IN THE COLDEST AREAS TO
NEAR 25 IN CENTER CITY PHILADELPHIA.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
A MILD AND DRY PATTERN IS FORESEEN DURING THE EXTENDED PERIOD.
RIDGING THAT BEGINS DURING THE WEEKEND WILL INTENSIFY EARLY NEXT
WEEK AND PERSIST THROUGH THE MID WEEK TIME FRAME. DAYTIME HIGH
TEMPERATURES WILL RANGE FROM 10 TO 15 DEGREES ABOVE NORMAL ACROSS
THE AREA. AS THIS IS TAKING PLACE A TROUGH OVER THE WESTERN STATES
WILL PROGRESS EASTWARD AND REACH THE MISSISSIPPI VALLEY WEDNESDAY.
THE DRY PERIOD WILL END LATER WEDNESDAY AS LOW PRESSURE SPINS UP
AHEAD OF THE TROUGH AND MOVES UP THE EAST COAST. SLIGHT CHC OF
SHOWERS ARE IN THE GRIDS TUE NIGHT IN THE WARM AIR ADVECTION PATTERN
AHEAD OF THE TROUGH AND CHC SHOWERS ARE IN THE GRIDS FOR WEDNESDAY.

&&

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
VFR FORECAST THROUGHOUT THE TAF PERIOD. LATEST TAFS REFLECT PREVIOUS
THINKING OF NOT MUCH SC AS THE FORECASTED SUBSIDENCE INVERSION IS
RATHER LOW EVEN IN UPWIND LOCATIONS FROM ABE AND RDG. THUS NO
CEILINGS AND JUST FEW SC MENTIONED IN ABE AND RDG TIL 08Z. MODEL
GUIDANCE SUGGESTING A SLOW RELAXATION OF THE PRESSURE GRADIENT
(WIND) OVER THE NEXT TWENTY-FOUR HOURS. MOMENTUM TRANSFER WINDS
REMAIN ROBUST THROUGH THE NIGHT WHICH MEANS WE WILL KEEP SOME
GUSTINESS GOING. THE LATEST NAM FORECAST SOUNDINGS FOR THURSDAY
MORNING SUGGEST THERE MAY BE A TWO HOUR WINDOW OF OPPORTUNITY WHERE
WIND GUSTS MIGHT REACH THE 30S AGAIN. NOT REFLECTED IN THE CURRENT
TAFS BECAUSE THE GFS FORECAST SOUNDINGS ARE NOT SHOWING THE SAME.
WINDS SHOULD DECREASE LATE IN THE DAY. NO CIGS EXPECTED THROUGH THE
FORECAST PERIOD. ON THURSDAY DAY THE FORECAST CONVECTIVE TEMPS ARE
PRETTY HIGH AND IF WE SEE ANY CLOUDS IT SHOULD BE SOME CIRRUS LATE
IN THE DAY. NO VISIBILITY RESTRICTIONS.

BEYOND THE FORECAST PERIOD, DRY WX IS EXPECTED AS HIGH PRESSURE
DOMINATES.

&&

.MARINE...
THE GUSTY WINDS HAVE CONTINUED THROUGH THE AFTN AND SHOULD CONTINUE
TO PICKUP A BIT MORE THIS EVENING WHEN GALE FORCE GUSTS ARE
EXPECTED. IN THE EVENING UPDATE WE WILL ADD LIGHT FREEZING SPRAY.
THIS MAY NOT BE A PROBLEM FOR POINTS NEAR 20 MILES OFFSHORE AS WATER
TEMPS ARE NEAR 50, BUT NEARSHORE WATERS ARE CLOSER TO 40F AND OUR
PROGRAM SUGGEST LIGHT FREEZING SPRAY IS POSSIBLE. THE GUSTY WINDS
WILL CONTINUE THROUGH THE NIGHT AS COLD AIR CONTINUES TO MOVE OVER
THE WARMER WATERS WITH A STRONG GRADIENT JUST OFF THE SURFACE. ON
THURSDAY MORNING, THE WINDS SHOULD DECREASE ENOUGH ON THE UPPER
PORTION OF DELAWARE BAY THE THE GALE WARNING SHOULD BE REPLACE WITH
A SCA, ON THE OCEAN AND LOWER BAY, GALES ARE ANTICIPATED UNTIL THU
EVENING. WINDS SHOULD CONTINUE TO DECREASE THURSDAY NIGHT WITH
SPEEDS EXPECTED TO DROP BELOW 25 KT BY FRIDAY. TRANQUIL WEATHER IS
THEN FORECAST THROUGH THE WEEKEND.

&&

.TIDES...
THE RIGHT DOWN THE BAY FLOW HAS CAUSED A RAPID INCREASE IN TIDAL
DEPARTURES OVER THE LAST SIX HOURS ON THE NEGATIVE SIDE TO REACH 3
FEET BELOW PREDICTED HEIGHTS IN THE UPPER DELAWARE BAY. TIDAL
DEPARTURES ON THE DELAWARE RIVER ARE AVERAGING ABOUT TWO FEET BELOW
NORMAL. IN CHESAPEAKE BAY THEY ARE LESS THAN TWO FEET BELOW NORMAL
AND BECAUSE THE WINDS ARE NW VS W THEY ARE NOT THAT FAR FROM NORMAL
ON THE OCEANSIDE. WE NEED DEPARTURES OF GREATER THAN TWO FEET BELOW
NORMAL IN GENERAL TO INITIATE LOW WATER PROBLEMS. AS SUCH THIS WILL
BE REACHED IN DELAWARE BAY AND SHOULD BE REACHED ON THE RIVER. WE
WILL ISSUE A LOW WATER ADVISORY FOR THE BAY AND AN SPS FOR THE
RIVER. ELSEWHERE THROUGH THIS LOW TIDE CYCLE, NO PROBLEMS ARE
EXPECTED. THE ENSUING LOW TIDE MIGHT ALSO BE A PROBLEM WHICH WE WILL
MENTION IN THE STATEMENT.
