Pretty detailed BTV AFD/area forecast discussion regarding the short term system.
.SHORT TERM /MONDAY THROUGH MONDAY NIGHT/...
As of 320 PM EDT Saturday...Positive thickness advection and an
influx of deep moisture should produce abundant clouds and
light precipitation on Monday. Temperatures at the onset of
precipitation should be cool enough to allow for some wintry
precipitation. Portions of the Northeast Kingdom and areas at or
above 2000ft agl should see some snow at the onset, followed by
transition to a wintry mix, and then rain. Forecast soundings
around Saranac Lake, NY and Nulhegan, VT have fairly complex
thermal profile with the inversion far aloft around 7000ft agl
only just above freezing with a layer below freezing sandwiched
in between wet-bulb temperatures near freezing at the surface.
Elsewhere, depth of warmer air is greater and stronger, which
would make for a cold rain. Overall, the best forcing and
precipitation takes place in the afternoon, with profiles
becoming above freezing with a quick transition towards rain
(except perhaps across the far northeast corner of Vermont).
Thus, it looks like a fairly damp and cool Monday with forecast
highs in the mid 40s. For such a weak low, the precipitation it
produces is impressive, aided by the deep-level of saturation
and good isentropic lift. Cross isobaric flow at potential
temperatures of 295K should lift moisture from around 850mb to
780mb with relative ease. Rainfall totals of 0.25"-0.50" seems
likely.
Weak surface low deepens as it departs eastwards. Some
northwesterly flow should allow precipitation to linger higher
peaks and near the foothills with semi-blocked flow and higher
relative humidities remaining. The DGZ becomes unsaturated,
though, and would likely not produce anything high quality from
the departing system. Overnight lows expected to fall into the
30s.
