A low pressure system will move into the canadian maritimes
tonight, with snow showers ending across our area. Seasonably
cold and mainly dry weather is expected tonight through
Thursday, except for some lake effect snow showers across the
western adirondacks. An upper level disturbance may trigger
additional snow showers for Thursday night into early Friday.

Fair weather, with a gradual warming trend is expected for this
upcoming weekend.

Near term until 6 am Thursday morning
As of 640 pm est... The winter weather advisories have been
canceled. Some upslope snow showers continue over the the
northern and central taconics into western new england, and
some lake effect snow showers and flurries continue over the
western adirondacks based on the kenx and mosaic radar and
observations. Some adjustments to pops and wx. Please see our
latest pns with snowfall totals. We will continue to update over
the next few hours.

Previous near term...

as of 415 pm est, still areas of mainly
light snow across the upper hudson valley extending south
through southern vt, the berkshires, and portions of the capital
region. Another band of light snow was edging eastward through
the central mohawk valley into schoharie co and heading east.

This second band appears to be tied close to the actual upper
level trough, and is expected to continue to move eastward over
the next 2-3 hours. This band could tend to flare up in
intensity as it tracks into the higher terrain of the taconics,
southern greens and at least northern berkshires.

Since this band will continue moving east during the main
evening commute, we decided to extend the previous winter
weather advisory until 8 pm this evening. Also, we have
downgraded the previous winter storm warning to an advisory,
also ending at 8 pm, for western new england (outside of
litchfield co ct). If trends continue with snow tapering off,
existing advisories may be cancelled earlier than the 8 pm est
expiration time.

For southern areas, the threat of any additional snow showers
appears much more limited, thus no warnings advisories at this

So, snow tapering to snow showers this evening, with additional
localized accumulations of up to 2 inches across portions of
southern vt, and only a coating to an inch elsewhere within the
advisory area.

Lake enhanced effect snow showers may also lead to a quick 1-3
inches across portions of the western adirondacks, ESP north of
route 28.

Eventually, subsidence in the wake of the upper level trough
should allow for some clearing to occur, especially in valley
areas. Some additional high clouds ahead of the next shortwave
may spill into the region toward daybreak.

With a fresh snowpack in place, it will not take much for the
boundary layer to at least briefly decouple, allowing temps to
drop off quickly into the single digits in most areas, if not
colder. However, if clouds and or wind persist longer, slightly
warmer overnight lows could result.

Short term 6 am Thursday morning through Saturday
Thursday, a mix of Sun and clouds, with chilly temperatures,
mainly in the 20s for lower elevations, and teens across higher
terrain. Some additional lake effect snow showers could lead to
an inch or two across far northern herkimer co.

For Thursday night, a potent upper level shortwave, currently
noted on WV satellite imagery across south central canada, is
expected to track across the region. With some added lake
moisture, and mid level warm advection combined with
strengthening cyclonic vorticity advection, a burst of snow
showers may occur, especially for areas near and north of the
i-90 corridor. Minor accumulations of up to an inch could occur,
except locally higher across portions of the western
adirondacks, and perhaps higher elevations of southern vt. Lows
should mainly be in the teens.

Friday-Saturday, after any residual snow showers Friday
morning, expect a clearing trend for later Friday into
Saturday, although snow showers could linger across the western
adirondacks. Friday highs should mainly reach the 20s to lower
30s, with Friday night lows in the teens 20s. Milder for
Saturday, with highs reaching the lower mid 30s across higher
terrain, to near or over 40 in valley areas, warmest across the
mid hudson valley region.

Long term Saturday night through Wednesday
Temperatures will close the weekend above normal, as high pressure
will be ridging in from the southeast and lower mid atlantic states.

The mid and upper level flow will be zonal closing the weekend, as a
cold front will be near the st lawrence river valley, and northern
new england. Lows temps Sat night fall back into mid and upper 20s,
and highs on Sunday will be about 10 degrees above normal with upper
30s to mid 40s in the valley areas and hills, and 30s over the mtns.

A few rain or snow showers may graze the western adirondacks with
the front nearby and weak disturbances in the fast flow through

Sunday night through Monday... An upper level trough moves in the
central plains, and closes off. Diffluent flow sets-up upstream
over the midwest and great lakes region. A warm front moves towards
ny and pa with a slight to very low chance of snow showers Sunday
night, though there are timing difference with the latest 12z
gfs ECMWF can ggem and gefs, and much of the night time period may
be dry. A lead mid-level short-wave coupled with the warm front may
produce spotty light pcpn into Monday, as the synoptic forcing looks
rather weak, but some light rain or snow showers looks possible. The
h500 low cuts off over the midwest and western great lakes region on
Monday. Lows Sunday night should fall back into the mid 20s to
around 30f before the clouds increase with the spotty light pcpn,
and highs in the warm advection regime will be in the mid 30s to
lower 40s.

Monday night through Tuesday... The low to mid-level southerly flow
increases ahead of the cutoff cyclone and its cold front, as the
latest 12z GEFS has +v-component wind anomalies southerlies
increase +2 to +3 standard deviations std devs above normal with
pwats increasing to 1 to 2 std devs above normal. Some snow melt,
and ice break is possible, as low temps will likely be above normal
with mid and upper 30s in the valleys, and upper 20s to mid 30s over
the higher terrain. The cutoff cyclone moves northeast into
southeast ontario with some gulf and atlantic moisture moving into
the forecast area ahead of the cold or occluded front with a
potential weak wave moving along it. The ptype could be messy with
rain mixed with sleet, then rain, and finally transitioning to snow
late in the day depending on the frontal passage. We will have to
monitor for any hydro issues especially with the present ice jams,
as highs will be in the mid and upper 30s north and west of the
capital region, and lower to mid 40s south and east. Total QPF may
be in the half an inch to inch plus range Mon night into Tuesday.

Tuesday night into Wednesday... The cold or occluded front moves
through with the pcpn ending as snow showers, as colder air filter
in. In the strong cold advection, lows fall back into the teens to
mid 20s. The threat for isolated to scattered snow showers
continues in the cyclonic flow, especially along the favored
westerly upslope areas of the western adirondacks southern
greens. High temps will be near normal for the mid week.

Aviation 00z Thursday through Monday
A coastal low will continue to move northeast towards the
canadian maritimes tonight. An upper level disturbance will move
through late tonight into tomorrow with some snow showers mainly
north and west of the hudson river valley. High pressure will
build in from the south and west late in the day into tomorrow

A mixture of MVFR andVFR conditions continue at
kgfl kalb kpsf kpou. The MVFR CIGS vsbys at kgfl kpsf should
only last a few hours with some snow showers reducing vsbys and
cigs around 1.5-3.0 kft agl. Expect improving CIGS between
01z-05z toVFR levels. Kalb has improved toVFR levels in terms
of CIGS vsbys, and should continue. Kpou has MVFR cigs, and
expect CIGS to rise toVFR levels prior to 04z with the
subsidence in the wake of the coastal low.

Vfr conditions will prevail after 06z with some high clouds. An
upper-level disturbance may allow for some sct-bkn stratocumulus
at around 3-3.5 kft agl to impact kalb kpsf btwn 09z-13z. We
placed a brief period of high MVFR CIGS at kalb. We were not
confident at the other terminals.

Vfr conditions will dominate late tomorrow morning through the
afternoon with few-sct stratocumulus and some scattered cirrus,
as some ridging builds in from the south and west.

The winds will be west to northwest at 5-10 kts tonight, and
then back a bit to the southwest to west, and then increase from
the west to northwest late tomorrow morning into the afternoon
at 8-12 kts with some gusts around 20 kts at kalb kpsf.


Thursday night to Saturday: no operational impact. No sig wx.

Saturday night: low operational impact. Slight chance of shra... Shsn.

Sunday: moderate operational impact. Chance of
shra... Shsn... Ra.

Sunday night: high operational impact. Likely ra.

Monday: high operational impact. Likely ra.

Ongoing flooding due to ice jams will continue to be addressed
with areal flood warnings, as some lingering issues continue
due to existing ice jams which have become frozen in place.

A gradual warming trend is expected to occur beginning this

In terms of precipitation, only some snow showers are expected
through Friday, with generally dry conditions expected over the
upcoming weekend.

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.
