Synopsis
High pressure building in from the north today will bring
gradually lessening chances for precipitation, pushing a
frontal boundary south of the area with some afternoon sunshine
expected, mainly across central and northern areas. A clear and
cold night is expected thereafter, with low temperatures widely
varying from the single digits to the upper teens above zero.

Unsettled and warmer weather returns for the end of the weekend
as developing low pressure over the central u.S. Pushes the
front back north Sunday afternoon into Monday, with periods of
rain, snow and mixed precipitation expected through mid-week.

Near term /through tonight/
As of 729 am edt Saturday... Precipitation waned overnight
across the north country as high pressure currently centered
over the southern tip of james bay continued to slowly sag
southward toward the international border. Surface observation
analysis shows the frontal boundary which brought yesterday's
rain, snow and sleet has shifted to our south, but a cold front
is still looming north of the border at this hour with
temps/dewpoints still holding in the upper 20s to low 30s around
montreal. Further north, north of say quebec city temps do drop
off significantly into the teens so it'll take a good chunk of
the day for this front to work it's way into the region,
beginning to clear out skies in the mid-afternoon across
northern areas, and towards sunset for central/southern zones.

Could see a few showers re-develop mid-day across southern
vermont, but for most of the area conditions should be largely
dry. With a little bit of sunshine we should realize high temps
in the mid/upper 30s with light winds this morning turning to
the north this afternoon at around 5-10 mph.

For tonight, clear skies and light winds combined with a deep late
season snowpack will once again set the stage for another round
of below normal temperatures. Some high clouds will try to
advance from the southwest late, but shouldn't hinder temps
dropping off into the single digits across the adirondacks and
central/northeast vermont, while the deeper valley locales will
mainly stay in the teens.

Short term /Sunday through Monday/
As of 402 am edt Saturday... .Large area of high pressure will
exist over eastern canada and northern new england Sunday
morning and move slowly east during the day. This will allow a
frontal boundary to move back northeast into the region late in
the day and especially Sunday night. As a result... The threat of
precipitation will increase from southwest to northeast across
the area Sunday afternoon and especially Sunday night.

Interesting thermal profile will exist over the area with colder
air in the low levels becoming established east of the greens
and eventually warmer air aloft moving gradually eastward over
the top of the shallow layer of colder air. The net result will
be the potential for mixed precipitation east of the
greens... Sleet and freezing rain... And there may even be some
freezing rain over northern new york where warmest air aloft
will exist. First wave of precipitation that lifts into the
region will not be significant... Nevertheless it will not take
much sleet or freezing rain to impact travel late Sunday
afternoon into Sunday night. More widespread precipitation will
spread from west to east across the area late Sunday night into
Monday. Thermal profile will change enough for most of the
precipitation to be in the form of rain across the area... But
there will still be a period Monday morning where mixed
precipitation will exist Monday morning. Situation will
definitely need to be monitored for any potential headline. High
temperatures on Sunday will be in the mid 30s to lower 40s and
in the upper 30s to upper 40s on Monday.

Long term /Monday night through Friday/
As of 402 am edt Saturday... Precipitation tapers off Monday
night... But drier weather will be short lived as upper trough
moves into the region on Tuesday with widespread rain expected
with highs in the 40s to around 50. Northwest flow will keep
some showers lingering in the mountains on Wednesday... But drier
weather expected for Thursday and Friday. High temperatures
will generally be in the upper 30s to upper 40s Wednesday
through Friday.

Aviation /12z Saturday through Wednesday/
Through 12z Sunday... Lifr to ifr conditions will generally persist
through mid-morning in low clouds and fog, then thereafter
we'll see a gradual improvement to MVFR from north to south by
18z, further trending toVFR/skc by 00-01z. Light and variable
winds turn northerly mid-morning at 5-10 knots, and return to
calm or light north after 00z.

Outlook 12z Sunday through Wednesday...

12z Sunday through 18z Sunday...VFR under brief high pressure
18z Sunday through Wednesday... Periods of mixed precipitation,
though mainly rain with cigs/vsby variable from ifr to MVFR.

Moderately gusty NW winds likely weds.

Btv watches/warnings/advisories
Vt... None.

Ny... None.

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.
