AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BINGHAMTON NY
1205 PM EST FRI DEC 1 2006

.SHORT TERM /REST OF TODAY THROUGH SATURDAY NIGHT/...
UPDATED THE AFTERNOON PERIOD TO INCLUDE SEVERE THUNDERSTORM WATCH
#875 FOR THE ENTIRE FORECAST AREA.  -MJ

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
LONGER RANGE GUIDANCE CONTINUES THE IDEA OF A COLDER PATTERN NEXT
WEEK.

OVERALL...NO MAJOR STORMS ARE EXPECTED...ALTHOUGH SEVERAL BOUTS OF
SNOW SHOWERS/FLURRIES ARE ANTICIPATED...AS NUMEROUS SHORT WAVES AND
REINFORCING TROUGHS COME THROUGH. LAKE EFFECT MECHANISMS WILL ALSO
BE IN PLACE. THUS...WELL HAVE A CHANCE OF SNOW SHOWERS ALMOST DAILY
FROM SUNDAY THROUGH WEDNESDAY...WITH AN EMPHASIS ON UPSTATE NY WHERE
THE INFLUENCES OF LAKE EFFECT SNOW WILL BE THE GREATEST. WELL GO
WITH ONE DRY DAY ON THURSDAY...FOR NOW...AS IT LOOKS LIKE HIGH
PRESSURE WILL BRIEFLY BUILD IN THIS PERIOD.

IT NOW APPEARS THAT A POTENTIAL COASTAL LOW EARLY NEXT WEEK (MAINLY
MONDAY) WILL BE FAR ENOUGH OFF SHORE TO PRECLUDE ANY REAL IMPACT ON
CENTRAL NY OR NORTHEAST PA. -MJ

.AVIATION /011200Z - 021200Z/...
NOT A GREAT DAY TO FLY. STATIONARY FRONT BISECTING THE BGM

INVERSION THIS MORNING AND FCST TO INCREASE...SO HAVE INCLUDED
LLWS AT THESE AIRPORTS. FRONT FCST TO GRDLY LIFT NORTH TO THE LAKE
ONTARIO PLAIN BY AFTERNOON...SO BETTER MIXING SHOULD OCCUR. THIS
IS WHEN WE WILL SEE S-SWLY SYNOPTIC FLOW INCREASE 20-30 KTS.
