139 am edt Wed mar 29 2017

A cold front will move through the north country overnight with
a chance of rain or snow showers. There will be a slight chance
for rain and snow showers on Wednesday, mainly over the high
elevations of the adirondacks and green mountains. A ridge of
high pressure will build into the region on Thursday with mostly
sunny skies expected. A low pressure area moving east across
the ohio valley will bring mixed wintry precipitation to the
north country late Friday into Saturday.

Near term /until 6 pm this evening/
As of 1108 pm edt Tuesday... Patchy drizzle, isolated -rw, and low
ceilings persist across the north country this evening, with
temps at 03z mainly 34-38f. Main synoptic feature of note is
the relatively compact, vertically stacked low exiting east of
nj. Main precipitation shield with this system will remain to
our south. However, as the low tracks ewd, will see increasing
n-nw winds, which will induce low-level CAA thru the remainder
of the overnight. Gradually cooling thermal profiles will allow
for a rain/snow mix as we move toward 04-05z along the intl
border, and elsewhere after 06z. Activity will be quite light
with orographics effects providing primary forcing mechanism.

Despite the low- level caa, continued cloud cover will help to
keep temperatures up overnight with lows mainly in the lower 30s,
except in the 20s over the higher elevations.

The region will be under cold advection on Wednesday. Expecting
a slight chance for some rain or snow showers on Wednesday,
mainly over the higher elevations of the adirondacks and green

Short term /6 pm this evening through Thursday night/
As of 400 pm edt Tuesday... Any residual rain or snow showers
should come to an end early Wednesday night. A ridge of high
pressure will build south from canada late Wednesday night and
will remain over the region through Thursday night. Expecting
mostly sunny skies on Thursday. A warm front will approach the
region well after midnight Thursday night, so will have a chance
of snow light snow late Thursday night and approaching daybreak
on Friday.

Long term /Friday through Tuesday/
As of 345 pm edt Tuesday... Snow expected to spread from north
to south across the north country on Friday with warming
temperatures during the day in southerly flow changing snow to
mostly snow. Some enhancement of QPF on eastern slopes expected
with shadowing effects on leeward slopes and valleys. Heading
into Friday night/Saturday morning, warmer air aloft will result
in wintry mix starting over northern ny and spreading eastward
into the champlain valley in the middle of the night. Northeast
kingdom has best chance of remaining snow through Saturday
morning. Winds shift out of the north on Saturday as the main
coastal low pulls east and northern stream shortwave that
provided lift for wintry mix will move out of the area with
generally drying conditions Saturday into Sunday. NW upslope
precip possible through Sunday before surface high pressure
becomes the dominant feature through Tuesday.

Aviation /06z Wednesday through Sunday/
Through 06z Thursday... Variable flight conditions fromVFR to
lifr will continue through 12-13z before all sites lift to MVFR
exceptVFR at kmss. Thereafter a gradual improvement at all
sites toVFR is expected by the afternoon. Areas of fog and
drizzle overnight generally dissipate after 12z as well, with
some lingering rain/snow showers across central/northern
portions of vermont through about 18z. Winds calm/light
overnight trend to the north/northwest at 5-15kts after 12z with
some gusts up to 20kts possible from the champlain valley
eastward through vermont.

Outlook 06z Thursday through Sunday...

06z Thursday through 12z Thursday... MainlyVFR. Isolated MVFR
and showers over higher terrain of NE vt.

12z Thursday through 12z Friday...VFR under high pressure.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
