Synopsis
High pressure building into the region today will provide the north
country with drying conditions and seasonable temperatures through
Saturday with highs in the 30s and lows in the mid teens to 20s. Low
pressure moving through the great lakes will bring a wintry mix to
the area Saturday night before a changeover to all rain during the
afternoon hours on Sunday. Strong and gusty southwesterly winds
ranging from 25 to 40 mph will also accompany the rain on Sunday.

Colder air returns to the north country next week with some
accumulating snow likely Sunday night into Monday, and teens for
highs and single digits for lows through mid-week.

Near term through Saturday
As of 627 am est Friday... A quiet period of weather is expected
for today through Saturday as surface high pressure gradually
builds over the northeast. Forecast challenge though will be
cloud cover as a strong subsidence inversion has set up over
most of the area this morning, helping to trap moisture and
clouds in the low levels. Looking at the latest forecast
soundings, it appears outside of the deeper valleys the
inversion may not break until mid-Saturday morning indicating
more clouds than Sun until Saturday afternoon. This in turn will
affect the high low temp forecast as well where milder temps
are expected tonight where more clouds persist.

Temps were very slow to drop overnight based on the abundance
of clouds, which means we'll start the day milder than normal
allowing afternoon highs to reach into the upper 20s to low 30s.

Tonights temps will be very tricky with a big bust potential if
any areas clear out as temps aloft drop to -5 to -10c. In
general think lows will be in the teens but won't be surprised
to see higher and lower values. Saturday continues to look like
the best day of the weekend with low clouds hopefully scouring
out by mid-day and temps rising above normal into the mid upper
30s. Some great spring skiing to be had so get out and enjoy!

Short term Saturday night through Sunday
As of 357 am est Friday... Active period of weather is expected
Saturday night into Sunday. Bottom line looking at a mixed
precipitation event starting late Saturday night and continuing into
Sunday. Low pressure stays northwest of our area... But its
associated warm front lifts up across our area. Warmer air aloft on
stronger southwest 850 millibar flow advances into the region during
the overnight hours and into Sunday morning. This creates a thermal
profile conducive to mixed precipitation. Warmest air aloft lifts
into northern new york and this results in a better chance for
freezing rain before changing to all rain during the morning hours
on Sunday. At this time looking at a tenth of an inch or less of ice
with minor amounts of snow and sleet before the freezing rain.

Definitely enough icing to potentially cause some travel issues.

Meanwhile across vermont warm air aloft moves in... But is not warm
enough for widespread freezing rain. Southern areas will have the
potential for some light ice accumulations with more snow and sleet
over the remainder of central and northern vermont where 1 to 3
inches of a snow sleet mix is possible before changing over to all
rain Sunday afternoon. Portions of the champlain valley will change
to rain during the morning hours on Sunday. Lows Saturday night will
generally be in the 20s and this will likely occur around midnight
or shortly thereafter before temperatures start to slowly rise
during the early morning hours. Highs on Sunday will range from the
mid to upper 30s across eastern vermont and in the 40s from the
champlain valley westward across the remainder of northern new york.

Accompanying the surge of warmer air aloft will be a strong jet at
850 millibars that will lift up across northern new york during the
overnight hours Saturday night. However... Precipitation will not
allow for deeper mixing and it looks like a more favorable time
period for stronger wind gusts will come Sunday night into Monday.

Long term Sunday night through Thursday
As of 357 am est Friday... Continuing the discussion on stronger wind
gusts for Sunday night and Monday it finally looks like enough
mixing will take place for stronger flow aloft to mix down. Sunday
night and Monday there is still strong flow at 850 millibars and
above over the area for a greater likelihood of very gusty winds. At
this time it appears the potential for wind gusts in the 40 to 50
mph range will be possible over the saint lawrence valley and
northern adirondacks Sunday night into Monday. At the highest
elevations in the northern adirondacks wind gusts in the 50 to 70
mph range will be possible. Further east across vermont lower
elevations should see wind gusts in the 30 to 40 mph range and in
the 40 to 60 mph range over the higher elevations. The wind
direction across the entire area will generally be from the
southwest Sunday night and then west and northwest on Monday.

Colder air moving in Sunday night and Monday combined with the flow
aloft becoming more west and northwest suggests the development of
upslope snow across portions of the northern adirondacks and along
and downstream of the green mountains in vermont as flow will be
unblocked given the speeds. Higher elevations will likely see some
minor snow accumulations. Colder and drier weather moves in Monday
night through Tuesday night. Fast moving low pressure system will
track across the region Wednesday and Wednesday night and bring
another shot of snow to the area with some minor snow accumulations
possible.

Aviation 12z Friday through Tuesday
Through 12z Saturday... Conditions will be largelyVFR through
the period under sct bkn low mid clouds with some periods of
MVFR at kmpv kslk, mainly this morning. Winds will be

trending calm overnight.
