636 am est Tue nov 20 2018

Light snow is expected across the north country today. Most of
the area will see less than two inches... But up to 4 inches is
expected across south central and southern vermont. The precipitation
comes to an end tonight and attention will turn to a sharp cold
front that will move across the area on Wednesday. Expect snow
and snow squalls with the front. Sharply reduced visibilities
and bursts of heavy snow will be possible with the snow squalls.

The precipitation comes to an end Wednesday night and very cold
air moves in for thanksgiving with dry conditions... But high
temperatures about 25 degrees below normal for this time of

Near term through Wednesday
As of 606 am est Tuesday... Overall going forecast in good shape
with light to moderate snow over the southern third of vermont.

Elsewhere have noticed fog being reported at most locations and
for this update have included areas of fog to the forecast for
the remainder of the morning. Rest of forecast in good shape and
no other changes needed at this time.

Previous discussion...

band of light snow continues across southern vermont... Essentially
south of a fair haven, vermont to west lebanon, new hampshire.

North of this line little in the way of precipitation is
occurring. Eventually a northern stream shortwave will move east
into the region and we should see some phasing later this
morning of these two features. Most areas will see less than two
inches of snow... But from rutland and windsor counties in
vermont southward up to 4 inches will be possible given the
longer duration of the precipitation across this area. The
morning commute may be impacted in this area. Highs will
generally be in the low to mid 30s.

The snow comes to an end later tonight and there should be a
lull overnight with lows from the mid teens to lower 20s.

Threat for snow squalls will exist on Wednesday as a sharp cold
front moves into the area. Steepening lapse rates... Dry
adiabatic to at least 700 mb... Suggests instability will be
developing ahead of the front. Strong pressure fall rise couplet
associated with shortwave trough moving across the area during
the late morning and afternoon hours will exist and snow squall
parameter values indicate the increase potential for snow
squalls as well. Thinking at this time is snow squalls will
develop over northern new york during the late morning early
afternoon hours and then move into vermont during the early to
mid afternoon hours. Sharply reduced visibilities and bursts of
heavier snow can be expected which will cause travel issues...

especially since it will be a busy travel day ahead of thanksgiving.

Have continued the mention of snow squalls and bursts of heavier
snow in the forecast. Highs will be in the 20s to around 30
with temperatures falling late in the day... Which could result
in any snow covered roads becoming icy.

Short term Wednesday night through Thursday
As of 405 am est Tuesday... Wednesday night and Thursday will
feature cold canadian ridge of surface high pressure building
into our area from the north. Chance for any light snow will be
dropping off during the first half of Wednesday night. Most
notable for this timeframe will be the very cold temperatures.

Temperatures will drop sharply Wednesday night behind departing
cold front. Minimum temperatures will dip into the single digits
above and below zero. This is about 20 degrees below seasonal
normals for late november. Then during the day Thursday with
strong cold air advection continuing, will have temperatures
only raising into the single digits above zero to the mid teens,
warmest in the saint lawrence and champlain valleys. It will
also be fairly windy during this timeframe, and we may have to
consider some wind chill headlines if this forecast holds true.

These daytime highs will be about twenty five degrees below
seasonal normals. Although very cold temperatures for thanksgiving
day, we may actually see some peeks of sunshine. Record low
maximum temperatures may be achieved on Thursday.

Long term Thursday night through Monday
As of 405 am est Tuesday... Thursday night and Friday will
feature surface and upper level ridging, bringing back dry
weather to the area once again. Thursday night will be another
cold one with temperatures similar to Wednesday night's
readings. Difference will be that the winds drop off with the
building high pressure overhead. See climate section below for
daily climate records for november 22nd and 23rd. High pressure
shifts further east Friday, allowing for the start of some warm
air advection within return southwesterly flow. High temperatures
over the weekend will generally be in the 30s. The next chance
for precipitation comes Saturday night Sunday as troughing
redevelops over the area and an upper-level disturbance moves
through. Details at this point have yet to be ironed out,
however, most likely scenario given the arrival of warmer air
will be a mix of rain and snow. There's yet another rain system
for the late Monday into Tuesday timeframe which may bring even
more rain to the north country.

Aviation 12z Tuesday through Saturday
Through 12z Wednesday... Ifr and lifr conditions are expected
through 00z as clouds, light snow, and fog persist over much of the
area. The precipitation will taper off between 00z and 06z with
visibilities improving into the MVFR andVFR categories. In
addition... Ceilings will improve into the MVFR category as well
during the 00z to 06z time period. Light and variable winds will
become west and northwest late this afternoon and continue for
the remainder of the period. However... Winds will generally be
10 knots or less.

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.
