Synopsis
High pressure continues to build southward out of canada this
afternoon. A clear and cold night is expected overnight, with
low temperatures widely varying from the single digits to the
upper teens above zero. Unsettled and warmer weather returns for
Sunday and Monday 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. A winter weather advisory has been raised for
light freezing rain.

Near term /through Monday/
As of 1031 pm edt Saturday... No changes needed to current
forecast. Surface high pres with clear skies and light winds
will allow temperatures to cool to near 0f slk/nek to mid teens
cpv/slv.

Challenging low temp forecast tonight as 1037mb high pres
located over southern hudson bay builds into the north country.

This has resulted in rapidly clearing skies this evening with
northwest winds at 5 to 10 knots and modest low level cold air
advection. Expecting a sharp low level thermal inversion to
develop in the deeper/protected valleys allowing for winds to
decouple and temps to quickly fall... Especially nek/slk. Have
noted 18z mavslk is now -1f... So based on this info and very
deep dry layer with ideal cooling conditions... With fresh snow
pack... Have cut temps across the dacks/nek back to around 0f.

Elsewhere... Some northeast winds at mss may keep temps up in the
mid teens slv and in the cpv. Sharp thermal inversion will
result in the coldest air temps in the deepest protected valleys
with midslopes/summits holding in the mid/upper teens.

Otherwise... Captured latest clearing trends and placed into sky
grids and made some adjustments to the dew points. Rest of
forecast in good shape.

Previous discussion below:
as high pressure continues to ridge into the north country out
of canada this afternoon and evening skies will clear from north
to south. Clear skies, light winds and the late season cold
snowpack overnight will bring about another cold overnight
period, generally single digits and teens. Some high clouds will
try to advance from the southwest towards early morning. The
overnight period will be dry.

More active weather returns for the short term portion of the
forecast. Have raised a winter weather advisory for western
essex county ny, and from the spine of the greens eastward for
light ice accumulations. On Sunday precipitation will begin from
the southwest and spread across our forecast area during the
afternoon hours. Precipitation should hold off till after 18z
and by that time temperatures should be warm enough across most
of the region to just expect rain at that point. Temperatures
should warm pretty quickly with some morning Sun across our
northern zones and warm air advection all day as low pressure
system lifts northward into great lakes region. Maximum
temperatures will reach the lower 40s across almost the entire
north country. The only exception will be western essex county
ny where there will be a threat for some freezing rain. Have
gone warmer than most MOS guidance for Sunday night due to
clouds and precipitation, as well as warm air advection across
the region, but still looks cold enough especially east of the
greens to cause some icing issues. Sunday night low pressure
system continues to push eastward towards our area, with more
precipitation expected. Have some categorical pops mentioned
overnight and then continuing into Monday with a front lifting
across our area. Warmer air aloft moves gradually eastward over
the top of the shallow layer of colder air, bringing with it the
threat for mixed precipitation especially east of the greens.

Colder air is tough to scour out there. It does not take very
much icing to impact travel. By about 15z Monday warm air
advection should be strong enough to have our entire area raise
about freezing with lower to mid 40s for afternoon high
temperatures. The low pressure system will be very slow to push
east of our region, and think there will still be some showers
around on Monday night, but temperatures should remain warm
enough to preclude any further issues. Mixed precipitation
always presents a complicated forecast.

Short term /Monday night through Tuesday/
As of 356 am edt Sunday... .Shortwave trough moves out of the
area Monday night and with best dynamic forcing now east of
us... Areal coverage of precipitation should decrease rapidly.

Some lingering showers near the canadian border through the
first part of the night will exist and that should be about it.

Next shortwave trough moves into the region Tuesday afternoon
and once again widespread precipitation should develop over
northern new york and vermont. High temperatures on Tuesday will
be in the mid 40s to lower 50s... Thus expecting precipitation
to fall in the form of rain.

Long term /Tuesday night through Saturday/
As of 356 am edt Sunday... Rain will decrease in areal coverage
from west to east Tuesday night as shortwave trough moves east
of the area. Colder air will begin to filter in and any
lingering precipitation will turn to snow showers. Northwest
flow aloft develops on the backside of the trough Wednesday and
Wednesday night and looking for some mountains snow showers in
this pattern. Drier air begins to move in Thursday and Friday
for no precipitation. Unfortunately data all over the place
heading into the weekend with timing of systems and have kept in
the chance for showers Friday night into Saturday. Highs on
Wednesday and Thursday will be in the upper 30s to mid
40s... Then in the 40s for Friday and Saturday.

Aviation /08z Sunday through Thursday/
Through 06z Monday...VFR conditions will persist through 00z
Monday with clear skies giving way to increasing mid/high clouds
from the southwest to northeast through the time period.

Thereafter, mixed precipitation spreads into the region lowering
cigs/vsby to at least MVFR, possibly ifr. Light winds tonight
turn to the south/southeast after 12z at 5-10 knots, exception
being kmss where directions will be more northeast.

Outlook 06z Monday through Thursday...

06z Monday through 00z Thursday... Periods of mixed
precipitation, though mainly rain with cigs/vsby variable from
ifr to MVFR. Moderately gusty NW winds likely Wednesday.

00z Thursday through 00z Friday... MainlyVFR, except for some
scattered snow showers over the adirondacks and green mountains.
