Synopsis
Light to moderate snow will move across the north country
tonight through the first half of Wednesday in response to an
approaching trough of low pressure. Once the trough passes to
the east Wednesday night most of the precipitation will come to
an end and the main story for the latter part of the week and
weekend will be a warming trend with highs in the upper 30s to
mid 40s.

Near term through Wednesday night
As of 312 pm est Tuesday... Winter weather advisory remains in
effect for rutland... Windsor... And orange counties of vermont
until 100 pm on Wednesday. Still looking at 3 to 5 inches across
the advisory area with localized amounts to 6 inches. Over the
remainder of the area amounts will be in the 1 to 3 inch range.

Bottom line... Very little has changed with how we feel this
event will play out. Upstream upper trough is move of an open
wave and its progressive... Which is why we are not thinking
heavy snow at this time. Tonight through midday on Wednesday is
when the majority of the snow will fall. The snow will taper off
quickly from west to east Wednesday afternoon. With all the
cloud cover tonight lows will not be able to fall too much and
have upped minimum temperatures tonight by a couple of degrees.

Highs on Wednesday will be in the 20s to around 30.

Short term Thursday through Friday
As of 312 pm est Tuesday... Expecting a fairly quiet but not
completely inactive end to the work week with shortwave energy
exiting east of the region Thursday morning, followed by a
series of 2 more weak northern stream shortwave troughs Thursday
night and Friday. In general, the deepest moisture is limited
to the higher elevations where a dusting to perhaps 2" is
possible, mainly Thursday night, but additional snowfall is
possible in the lee of lake ontario with some lake enhancement.

The period will also mark the beginning of a gradual moderation
in temperatures which will last into the weekend and early next
week. Highs Thursday will range through the 20s, and warm to the
upper 30s to mid 30s for Friday, with lows Thursday night
mainly in the teens.

Long term Friday night through Monday
As of 312 pm est Tuesday... Overall little change from the 00z
to 12z nwp guidance in regards to the long term pattern which
continues to highlight moderating temperatures and building
heights across the eastern seaboard between high pressure
anchored offshore and a developing mid-level closed low over the
central plains. For Friday night through Sunday the forecast
area will be on the northern fringe of a warm frontal zone with
a fast zonal flow aloft. Not looking at any appreciable
precipitation during the period, but can't rule out a few
rain snow showers. Temps continue to climb from the end of the
work week with 925-850mb temps in the -3c to +3c range
supporting highs both days in the 30s to low 40s and lows in the
20s.

Forecast becomes more active and complex heading into Sunday night
through Tuesday as the aforementioned closed upper low and
associated surface frontal system shift northeast into the great
lakes by mid-day Monday, then further northeast into central quebec
by Tuesday morning. This track puts the north country firmly in the
warm sector on Monday with thermal profiles supporting the chance
for a light wintry mix as the warm frontal zone lifts northward
through the area Sunday night into early Monday morning. Entrenched
in the warm sector by mid-day Monday, precipitation chances wane as
a modest low mid level jet of 35-50kts moves through the region, but
quickly ramp up from west to east in the afternoon ahead of the cold
frontal boundary. Indications are for a good slug of widespread
rainfall to occur Monday afternoon and early overnight before a
transition to snow late Monday night. Right now we don't anticipate
as much QPF compared to what fell at the end of last week, but
nevertheless, several days of temps in the 40s combined with even a
modest rainfall will bear watching for another round of hydro
concerns.

Aviation 20z Tuesday through Sunday
Through 12z Wednesday... Generally looking atVFR and MVFR
conditions in response to light snow. After 00z steadier snows
move in and ceilings and visibilities lower into the MVFR and
ifr categories with some lifr conditions between 06z and 12z.

Slow improvement on conditions will occur after 12z as snow
moves east of the area. Winds will generally be under 10 knots
through the period.

Outlook...

Wednesday night:VFR. Slight chance shsn.

Thursday: mainlyVFR, with areas MVFR possible. Slight chance
shsn.

Thursday night: mainlyVFR, with areas MVFR possible. Chance

Friday: mainly MVFR, with localVFR possible. Slight chance shsn.

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.
