Synopsis
Milder but breezy weather is expected for this afternoon with
highs in ranging from the mid 40s to mid 50s. A cold front will
move through the region late tonight and Wednesday, bringing
scattered rain and snow showers. Thanksgiving day is expected to
be dry with temperatures in the 30s.

Near term through Wednesday night
As of 134 pm est Tuesday... Forecast on track this afternoon for
sunny and windy with highs from the mid 40s to the mid 50s. 88d
vwps show ssw winds up to 40kt right now at kcxx ktyx so
forecast of wind gusts 20-40 mph until sunset.

A cold front will approach the region from the west overnight
reaching the st lawrence valley around 09z, then moving east
into the champlain valley just after 12z, and ct valley by 16z.

A band of precipitation will accompany the front and boundary
layer temperatures should be warm enough to support mainly just
rain showers as 925mb temps don't drop below 0c until the front
passes. It should be cold enough in the higher elevations to
support a change to snow showers as the front moves by. Not
expecting much in the way of rain or snow accumulation with
perhaps a tenth or two of QPF mainly rain, but mainly snow at
the mountain summits for 1-3" above 3000 ft and an inch or less
down to the bases of the mountains as temperatures drop.

Tomorrow morning any lingering orographically driven rain snow
showers in the valleys and snow showers in the higher terrain
will gradually wind down during the afternoon. Expecting
temperatures to hold fairly steady from around 30 in the
adirondacks to 40 in the valleys before falling again toward
dark.

Should be quiet Wednesday night as a weak ridge of high pressure
builds in from the west and height rise aloft. Still could be
some pesky clouds hanging on in the mountains with low temps
ranging from the mid teens to mid 20s depending upon cloud
cover.

Short term Thursday
As of 222 am est Tuesday... Overall the short term period
continues to look quiet with high pressure cresting over the
region on thanksgiving day. Variable cloudiness is expected
though with an upper trough exiting the region Wednesday night,
and mid high clouds increasing thanksgiving day in advance of
the next system, but we should see some peaks of sun. Temps will
be seasonably cool with lows in the teens 20s and highs ranging
through the 30s.

Long term Thursday night through Monday
As of 222 am est Tuesday... While the long term period continues
to look active, there are no really no big systems on the
horizon to speak of. The tail end of a decaying cold front will
bring some scattered snow showers to the region Thursday night
into Friday morning, followed by brief high pressure for the
remainder of Friday into early Friday night. The weekend
continues to look unsettled, but the latest trends are for one
area of low pressure to track well north of the region, and
another well offshore on Saturday, both delivering limited
impacts to the northeast. The best chance for precipitation
actually now appears to be post-frontal passage Saturday
afternoon night and through the weekend where upslope flow will
enhance snow shower activity across the higher elevations. It
will be noticeably warmer for Friday and Saturday though with
deep southwesterly flow developing aloft. Highs should bump into
the 30s 40s before falling back into the 20s 30s for
Sunday Monday as the upper trough settles overhead.

Aviation 18z Tuesday through Sunday
Through 18z Wednesday...VFR but with south to southwest winds
gusting 25-35 kt until just before sunset. Clouds and rain showers
will begin to move into the area from the west tonight ahead of
a cold front reaching near btv near 12z with ceilings lowering
to MVFR. Winds will be shifting to wnw around 10 kt behind the
front and falling temperatures will bring a change to snow
showers and ifr vsby mainly at slk tonight and mpv tomorrow
morning. Not expecting much of accumulation but could be a
coating at slk.

Wednesday night:VFR. No sig wx.

Thanksgiving day:VFR. No sig wx.

Thursday night: MVFR. Chance shsn.

Friday: mainlyVFR, with local MVFR possible. Slight chance shsn.

Friday night:VFR. Slight chance shsn.

Saturday night: MVFR ifr conditions possible. Chance shsn, chance
shra.

Marine
As of 134 pm est Tuesday... Lake wind advisory in effect for
winds 20-30 kts out of the south with gusts approaching 40 kts.

Winds currently 32 kt at colchester reef and 23 kt at diamond
island. This will create significant wave heights 3 to 6 ft.

These conditions may prove hazardous to those operating small
craft, especially on the broad lake and in vermont bays inlets
with southerly exposures. Gusty south winds will abate
overnight.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
