high chances for mixed precipitation and/or snow to eastern New York
and western New England today into Saturday.

into Monday. Forecast guidance currently supports for low to
medium chances of light snow south of I-90.

.DISCUSSION...
KEY MESSAGE 1...
Latest surface observations show the low pressure system just
to the west of the Great Lakes region. High resolution model and
ensemble forecast model guidances continue to be in agreement
for this low pressure system to move through the Great Lakes
region today and bring an occluded front through eastern New
York and western New England later this morning into Saturday.
The current forecast supports onset timing to still be between
late this morning and early afternoon. Precipitation is likely
to begin as snow. The type of snow is going to be interesting as
instead of the fluffy/flake like snow, it`ll likely be more of
small pellet-like snowflakes that fall. Temperatures are going
to contribute greatly to when the type of precipitation changes
over during the late afternoon and evening hours. If
temperatures hover around and above freezing, a mix of freezing
rain and rain is likely across locations south of I-90. For
locations north of I-90, a mix of freezing rain, sleet, and snow
is likely before transitioning over to all snow for this
evening. An important forecast note is that the Greater Capital
District region and Mid-Hudson Valley could become dry by Friday
evening for the best case scenario of low precipitation
amounts, in both ice and snow. The eastern Catskills and Mohawk
Valley have the highest probabilities to see between 0.1 and
0.25 inches of ice accumulations as temperatures contribute to a
longer period of a wintry mix during the afternoon and early
evening hours. Precipitation chances decrease for Saturday
morning and afternoon for lingering light snow showers before
drier conditions return Saturday night.
Winter weather headlines continue across eastern New York and
western New England for late this morning through tomorrow for
slick and slippery conditions due to ice accumulations and snow
accumulations. Snowfall total amounts across eastern
Schenectady county have increased to between 2 and 4 inches for
them to be included in the Winter Weather Advisory. Rain will
be the likely precipitation type after the transition from snow
across the Mid-Hudson Valley and portions of the Greater Capital
District for tonight.
KEY MESSAGE 2...
Ensemble forecast model guidances continue to be in good
agreement for a coastal low storm to develop off the Atlantic
coast. The latest forecast supports a track for the center of
the low to stay off-shore. However, latest trends in ensemble
forecast model guidances have the center a little further north
than previous forecasts. This brings low to medium chances for
light snowfall and breezy conditions across locations south of
I-90. Wind gusts have increased to between 25 and 30 mph across
the Mid-Hudson Valley, southern Taconics, and Litchfield Hills
for Sunday afternoon into Monday afternoon. There is still
uncertainty in the exact track of the coastal low for two
additional scenarios to happen. If the track of the low moves
further inland, we could see higher chances of snowfall. If it
moves further out to sea, we`ll see even lower chances for snow.
Nevertheless, the latest forecast continues to support low
chances of minor impacts to travel for Monday morning with light
snow amounts south of I-90. Continue to monitor latest
forecasts as we get closer in time.

.AVIATION /07Z FRIDAY THROUGH TUESDAY/...
Through 06z/Saturday, VFR Vsbys expected through sunrise with
Cigs bordering VFR/MVFR, with mainly MVFR Cigs at KPSF.
Precipitation is then expected to overspread the TAF sites from
south to north between 13Z-16Z/Fri. Initially, most TAF sites
will start as snow, except possibly a rain/snow mix at KPOU.
After 2-3 hours of light to moderate snow, precipitation should
change to a mix of sleet/rain except freezing rain and sleet at
KPSF. At KGFL, all snow is expected with perhaps a brief mix
with sleet later in the afternoon. Precipitation should then
change back to snow from north to south between 23Z/Fri and
02Z/Sat. Flight conditions should drop to IFR/LIFR (both Cigs
and Vsbys) once the snow begins, with mainly LIFR/VLIFR at KGFL.
Light/variable winds through daybreak except southeast at 5-10
KT at KALB. Winds will increase from the east/southeast to 8-12
KT later this morning, then gradually back into the northeast to
north at 5-10 KT this afternoon/evening. Winds may be gusty at
times at KPSF from the east by early this afternoon, reaching
20-25 KT before decreasing later this afternoon. Low level wind
shear is also expected at KPSF this afternoon as winds around
2000 FT AGL increase from the east-southeast to 30-40 KT.
