.DISCUSSION...

KEY MESSAGE 1...

Steady rain is leaving the Poconos and Catskills as of 130 PM as
a cold front exits the region. In the wake of the frontal
passage, temperatures will gradually fall this afternoon as the
flow becomes northwesterly and ushers in much colder air. 850mb
temperatures fall from about 5C early this morning to near -10C
by early Monday morning. This combined with strong low and mid-
level lapse rates will be enough to lead to a response off the
lakes and the development of scattered snow or rain/snow showers
starting late this afternoon and evening and continuing through
Monday. Snowfall amounts through Monday morning are expected to
be light ranging from a dusting to perhaps near a half inch in
some places, mainly in higher terrain of CNY. Lows Sunday night
range from the upper 20s to the low 30s. Monday`s highs are
expected to be in the upper 30s and 40s, but the valley areas of
NE PA can reach the upper 40s to near 50 degrees.

A clipper system and supporting upper trough is expected to
move in Monday night into Tuesday, drawing down even colder air
into the region and bring a more widespread round of mainly snow
showers. Tuesday`s highs will be mainly in the 30s, while
overnight lows Tuesday night drop back into the teens and low
20s giving us quite the winter chill stepping out the door early
Wednesday morning.

KEY MESSAGE 2...

As the flow aloft becomes more zonal and even features some
slight ridging and high pressure builds in at the surface, drier
conditions are expected Wednesday and Thursday with moderating
temperatures into late week. High temperatures are expected to
go from the 40s and 50s Wednesday to the 60s area-wide by
Friday. While Wednesday night still looks chilly, overnight lows
return to the 40s Thursday and Friday nights.

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
18Z Update...
Steady rain has exited, and now the terminals have entered a
post-frontal regime with flow from the west-northwest bringing
in a 2-4 kft agl ceiling and cooler air. A minor lake effect
response will also yield mixed rain-snow showers tonight, at
times lightly impacting KSYR-KRME. KAVP is likely to improve to
VFR later this afternoon and remain there, whereas the NY
terminals will fluctuate in and out of it overnight before
settling at least for a time at VFR.

Outlook:

Late Monday through midday Tuesday...A clipper system will brush
by with initially mixed rain-snow showers, becoming scattered
snow showers with possible restrictions, as colder air is
reinforced across the area.

Late Tuesday through Thursday Night...Mainly VFR.

Friday...A weak frontal zone may encroach into the area with a
chance of rain showers and associated restrictions.
