Synopsis
A cold front entering ny from the west will bring chilly
temperatures and a quick shot of rain and snow showers to our
area early Wednesday morning. Light lake effect snow showers
will continue through midday across northern ny.

Near term through Wednesday night
235 pm update...

while Tuesday felt more like a mid-october day with temperatures
well into the 50s, a storm system moving out of the great lakes
will combine with a deepening trof to bring a quick shot of rain
and snow showers, then much colder temperatures.

This frontal system is moisture-starved, so except where the
lakes are involved the precipitation will be short-lived. A
dusting to a half-inch of snow is forecast at the tail-end of
the precipitation early Wednesday morning.

A strong polar push behind the front will lead to a non-diurnal
temperature trend. Our maximum temperatures will occur Wednesday
morning, before readings fall throughout the afternoon.

Around an inch of snow is forecast downwind of lake ontario on
Wednesday. Winds will gust at 20 to 30 mph over the western
mohawk valley.

1055 am update...

temperatures are rapidly warming this morning, with the latest
guidance continuing to point to maximums north of 50 degrees
this afternoon.

The grids are updated - mainly alterations to the near-term
temperatures - and should be available shortly.

Short term Thursday through Friday
3 pm update... Overall, a quiet period is foreseen on
thanksgiving day and Friday, which should be favorable for
traveling.

By thanksgiving day, surface ridging building northward from the
mid-atlantic states should lead to a mainly dry day. Any light
snow showers or flurries, well out ahead of a weak surface
boundary and southern canadian short-wave should be
inconsequential, and relegated to our far northern zones
(southern tug hill region of cny). Afternoon highs should range
in the 30s.

The above mentioned weak disturbances may continue to bring some
flurries, sprinkles, or light rain snow showers Thursday night
into Friday morning for upstate ny, before the systems lift away
to our northeast during the day Friday. Otherwise, dry weather
should persist, with partly sunny partly cloudy skies. By Friday
afternoon, highs should range from the upper 30s-mid 40s.

Long term Friday night through Monday
315 pm update... Although on the large-scale, a western
canadian western CONUS ridge and an eastern CONUS trough should
prevail in the upper levels, each of these features appear to be
on the flat side, which should allow a quick w-e progression of
systems through cny nepa about every 2-3 days. It seems like
none of these systems will have time to acquire significant
moisture, so overall precipitation amounts look light. Also, on
average, temperatures should be near to slightly below normal
for late november.

As for the daily sensible weather, a short-wave and associated
surface cold front are slated to come through cny nepa on
Saturday, accompanied by at least scattered rain showers. Colder
air will filter into the region behind the front, from the
second half of the weekend into early next week. This colder air
mass will combine with lingering low-level moisture and upper
troughiness, to bring the likelihood of lake-effect snow
showers for portions of cny. Early indications point to a
280-300 prevailing flow, which would favor some of our northern
zones in cny for at least nominal snow accumulations (cayuga,
onondaga, madison, and oneida counties). Overall, moisture
appears shallow from this early vantage point, and a ridge axis
is also progged to quickly build towards cny nepa from the west
by Monday. As a result, our initial inclination is that this
will not be a significant or longer duration lake-effect snow
event.

Aviation 20z Tuesday through Sunday
Vfr conditions and gusty winds will continue through the
daylight hours today before clouds thicken late tonight. A cold
front will usher in MVFR ceilings and a mix of rain and snow
showers early Wednesday morning.

A few snow showers will continue through midday-Wednesday in
the vicinity of syr and rme, but coverage is forecast to be too
spotty to include with this TAF package.

Most terminals should return toVFR Wednesday afternoon.

Outlook...

late Wednesday through Friday... MainlyVFR.

Friday night through Saturday... Possible restrictions in rain,
especially Saturday. Snow may also be mixed in early.

Bgm watches warnings advisories
Pa... None.

Ny... None.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
