AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW YORK NY
732 PM EDT WED SEP 22 2010

.SYNOPSIS...
A COLD FRONT MOVES ACROSS THE AREA TONIGHT. HIGH PRESSURE THEN
BUILDS INTO THE AREA THURSDAY. A WARM FRONT MOVE NORTHWARD
THURSDAY AFTERNOON. A LOW PRESSURE SYSTEM MOVES THROUGH THE GREAT
LAKES THURSDAY NIGHT AND FRIDAY...INTO NORTHERN NEW ENGLAND BY
FRIDAY NIGHT. THE COLD FRONT WITH THIS LOW MOVES THROUGH FRIDAY
NIGHT INTO SATURDAY. HIGH PRESSURE THEN BUILDS FROM THE NORTH INTO
THE BEGINNING OF NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
TSTMS MOVING ACROSS WESTERN ZONES. PLENTY OF DESTABILIZATION
OCCURRED AHEAD OF THIS ACTIVITY...SO IT SHOULD HOLD TOGETHER FOR A
LITTLE WHILE TONIGHT.

THREAT LESS LIKELY COASTAL AND EASTERN SECTIONS WITH MARINE
INFLUENCE. MAIN OVERALL THREAT WILL BE GUSTY WINDS.

FRONT MOVES THROUGH 03Z TO 08Z WITH THE THREAT OF SHOWERS AND
THUNDERSTORMS ENDING. NOT A STRONG PUSH OF COLD ADVECTION BEHIND
THE FRONT. USED A BLEND OF THE GUIDANCE FOR LOWS TONIGHT.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/...
COLD FRONT STALLS SOUTH OF THE AREA BY EARLY THURSDAY
MORNING...AND DEEPENING LOW MOVES INTO THE CENTRAL PLAIN STATES.
THIS LOW WILL BRING THE FRONT BACK NORTH AS A WARM FRONT THURSDAY
AFTERNOON INTO THE EVENING. SO AREA WILL BE WARM SECTORED THURSDAY
NIGHT INTO FRIDAY. COLD FRONT IS APPROACHING FRIDAY NIGHT HOWEVER
NOT FAVORABLE DYNAMICS SO WILL LEAVE DRY FOR NOW.

TEMPERATURES FRIDAY WILL BE IN THE UPPER 80S TO NEAR
90...APPROACHING RECORD LEVELS.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
MODELS START OUT IN AGREEMENT THAT SATURDAY-SATURDAY NIGHT WILL
FEATURE WSW FLOW ALOFT...FOLLOWED BY A 500 HPA SHORTWAVE TROUGH
PASSING ALONG THE SE CANADA/NE US BORDER SUNDAY...WHILE AT THE
SURFACE  WITH A DRY FRONTAL BOUNDARY SLIDES TO OUR SE AS HIGH
PRESSURE BUILDS IN TO THE NORTH SATURDAY-SUNDAY. HAVE GONE WITH A
DRY FORECAST AS A RESULT THROUGH SUNDAY. FOR
TEMPERATURES...BASICALLY USED A MEX/MEX ENSEMBLE MEAN BLEND...THOUGH
DID UP A FEW DEGREES ON SATURDAY...AS GFS SEEMS A TAD FAST ON COLD
FRONTAL PASSAGE...AND WITH 850 TEMPERATURES IN THE EARLY AFTERNOON
UP TO 16C...COULD SEE SOME LOWER 80S...ESPECIALLY ACROSS EASTERN
CT...AND MAYBE EVEN A FEW DEGREES WARMER...DEPENDING ON CLOUD COVER
AND EXACT TIMING OF THE FRONT.

MODELS THEN DIVERGE ON HANDLING OF CUTOFF LOW FORECAST OVER THE NW
OK/CENTRAL MO AT 00Z MONDAY...ESPECIALLY SINCE THIS LOW IS NOT EVEN
WITHIN THE NORTH AMERICAN RAOB NETWORK YET...THE UNCERTAINTY WITH
THIS SYSTEM REMAINS HIGH. WITH GFS A SW OUTLIER IN HANDLING OF THIS
SYSTEM...AND THE ECMWF FAIRLY CONSISTENT...HAVE OPTED FOR THE ECMWF
IN HANDLING EXTENDED FROM SUNDAY NIGHT-WEDNESDAY.

AS A RESULT...EXPECT DAMMING HIGH TO SLOWLY RETREAT NE FROM SUNDAY
NIGHT INTO TUESDAY...WITH A COMPLEX STORM SYSTEM SETTING UP OVER THE
OHIO VALLEY REGION IN ASSOCIATION WITH THE CUT OFF LOW. AS A RESULT
WOULD EXPECT OVER-RUNNING RAINS TO BEGIN TO REACH THE AREA MAYBE AS
EARLY AS LATE MONDAY AFTERNOON...THEN CONTINUE TO OVERSPREAD THE
AREA MONDAY NIGHT (COULD SEE SOME ISOLATED SHRA BEFORE THIS SUNDAY
NIGHT...WITH A SHORTWAVE TROUGH PASSING TO THE NORTH). AS FOR
TEMPERATURES USED A MEX/MEX ENSEMBLE MEAN BLEND..TWEAKING WHERE
NEEDED TO BETTER FIT ECMWF SOLUTION (MAIN CHANGE WAS TO LOWER HIGHS
MONDAY/RAISE LOWS MONDAY NIGHT TO REFLECT SMALLER DIURNAL RANGE DUE
TO OVER RUNNING CLOUDS.

EXPECT ASSOCIATED SURFACE WARM FRONT TO BLOW THROUGH THE REGION
TUESDAY MORNING...PUTTING THE AREA SOLIDLY IN THE WARM SECTOR
TUESDAY-WEDNESDAY...SO CHANCE SHRA/TSRA THAT TIME FRAME. WITH
CONDITIONS GENERALLY CLOUDIER/WETTER THAN GFS...TOOK MEX/MEX BLEND
AND RAISED LOWS AND LOWERED HIGHS TO REFLECT ANTICIPATED SMALLER
DIURNAL RANGE. IF WE END UP WITH MORE SUNSHINE TUE/WED THAN
CURRENTLY EXPECTED...HIGHS COULD BE 5-10 DEGREES TOO LOW...WITH
850 TEMPERATURES FORECAST AROUND 15C.

&&

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
A COLD FRONT MOVES THROUGH TONIGHT...AND HIGH PRESSURE WILL BUILD
TO THE NORTH THURSDAY.

THUNDERSTORMS WILL IMPACT AREA TERMINALS...NYC METRO
INITIALLY...THEN THIS ACTIVITY MOVES EAST. SLOW CLEARING OCCURS
OVERNIGHT. PATCHY FOG POSSIBLE IF WINDS ARE LIGHT ENOUGH. VFR
THURSDAY.

WINDS WILL BE QUITE TRICKY BEFORE MIDNIGHT. A GENERAL SOUTH WIND
WILL EVENTUALLY TURN TO THE NORTH AFTER MIDNIGHT. COULD OBSERVE
VARIABLE WINDS FOR A SHORT TIME AS THE FRONT MOVES THROUGH.

NORTH TO NORTHEAST THURSDAY MORNING...THEN SOUTHEAST DURING THE AFTERNOON.
