Synopsis
High pressure over the north country this morning will give way
to unsettled and warmer weather for tonight and Monday as
developing low pressure over the central u.S. Pushes a warm
front northward through the region. Periods of freezing rain
tonight into Monday will transition to all rain by Monday
afternoon, briefly tapering off Monday night before returning
for Tuesday and ending as snow Tuesday night.

Near term /through Monday/
As of 443 am edt Sunday...

Freezing rain advisory in effect for portions of the north
country tonight...

a relatively quiet day is on tap for the north country to end
the weekend as high pressure centered over eastern quebec
continues to provide mainly sunny and dry conditions to the
region. We'll see some increasing mid/high clouds through the
day with chances for precipitation increasing from the southwest
beyond the 4pm hour and heading into this evening. Highs will
run slightly below normal for late march in the mid/upper 30s to
around 40 in the champlain valley.

For tonight into Monday, concerns remain from the previous
forecast thinking in regards to freezing rain potential as deep
low pressure north of the ozarks this morning will push a warm
front from southwest to northeast into the forecast area
tonight. Thermal profiles are as such that freezing rain will be
the dominant ptype across essex county of new york and from the
western slopes of the green mountains eastward where surface
temps will hover a freezing or just below as warmer air aloft
moves over the area. In the deeper champlain and st. Lawrence
valleys surface temps remain in the low/mid 30s overnight so
while pockets of freezing rain are certainly possible, the
overall impacts will be minimal. On the impact side of things,
under the advisory area, there is some concern that impacts will
be on the low side through much of the event as modeled road
temperatures show surfaces warming well above freezing during
the day, and only right to freezing during the overnight. The
expected ice accumulations won't have an impact on powerlines as
only up to a tenth of an inch is expected at the lower
elevations, and even though higher up on the mid-slopes
increased amounts could accumulate onto the larger transmission
lines, they can usually handle a little more without failing.

Freezing rain will be falling during the Monday morning commute
though so any ice on area roadways will be a concern.

By mid-day Monday the warm front pushes closer to the canadian
border allowing surface temps to warm into the mid-30s east to
upper 40s west transitioning ptype to plain rain and ending the
threat of ice accumulation.

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.
