.DISCUSSION...
KEY MESSAGE 1...

An upper level trough currently over the Great Lakes will help
to push a surface low pressure system into our area from the
southwest this afternoon. Precipitation will start as rain as
temperatures are in the mid- to upper-40s area-wide. As the main
center low passes overhead tonight, colder air pushes in, and
rain will transition into snowfall. As it does, wet surfaces
may become icy as temperatures approach and fall below freezing.
Uncertainty still lies for NE PA and the Southern Tier, as
trends keep slowing the introduction of colder air, as well as
QPF trending slightly slower. With the slower introduction of
colder air, the transition from rain to snow may be slower, but
it will most likely occur west-to- east after 2am EST.

A Winter Weather Advisory was issued for tonight through early
afternoon tomorrow for most of central NY and Bradford and
Susquehanna Counties in PA. For the counties impacted by the
following lake effect snow, the advisory is in effect until
Friday early afternoon.

Following the departure of this system, lake effect snow develops
under west to northwesterly flow. This will result in additional
snowfall for the eastern Finger Lakes and Mohawk Valley regions
through Friday morning. A ridge of high pressure then builds
into the region Friday afternoon, bringing an end to the lake
effect snow.

KEY MESSAGE 2...

Under a broad trough, the cold and snowy pattern will continue
through early next week. Another shortwave trough will dig over the
eastern US this weekend, with a weak clipper system expected to pass
north of the region and will bring a chance for scattered,
light snow showers to the region over the weekend.

A more organized system moves over the Atlantic late Sunday,
but is not expected to have any impact for our region. This
trough will also bring a surge of colder air leading to
temperatures going from the 30s on Saturday to 20s on Sunday.
Another surge of colder air is expected early next week as a
more broad shortwave swings through. There is some uncertainty
on how cold this surge will be though early next week looks to
be blustery with temperatures trending even colder and gusty
winds expected. Any snow early next week will be in the form of
lake effect and mainly limited to central NY.

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
Mostly MVFR to Fuel Alt ceilings are initially expected before
IFR conditions settle in a little later this evening. Rain will
gradually mix with snow overnight and eventually transition to
snow early Thursday morning, which will result in widespread
IFR or worse visbys and ceilings. Gradual improvement from west
to east is expected very late in the period, but lake effect
snow showers may continue to bring IFR conditions to SYR and RME.

Outlook...

Thursday night...Restrictions likely with lingering snow
showers, especially at the Central NY terminals.

Friday through Friday night...Mainly VFR, although occasional
restrictions possible at KRME and KSYR with some light snow
showers.

Saturday through Sunday...Restrictions possible in scattered
snow showers.

Monday...Cold front approaches the region with restrictions
possible.
