.SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/...
Winter Weather Advisory for Dutchess, Litchfield and Berkshire
Counties from midnight tonight through noon Friday...
So, snow begins tonight, continuing through daybreak, then
exiting through Friday morning. Snow amounts of 2 to 5 inches
are possible in southern parts of the mid Hudson Valley, into
the Litchfield Hills and Berkshires, so Winter Weather
Advisories have been issued there. A dusting to 2 inches is
possible elsewhere with 1 to 3 inches in southern VT. Some of
the higher peaks of southern VT could see locally higher
amounts. Winter Weather Advisories may be considered later for
southern VT if a more widespread 3"+ snow zone is expected
outside of the higher peaks of the southern Green Mountains.
Some lake effect snow shower activity should develop Friday
night but as low level flow turns northwest to north northwest,
the lake effect activity should shift to the western Mohawk
Valley, Schoharie Valley and eastern Catskills through Friday
night. Some clearing should occur toward daybreak as the low
level flow turns north northwest to north northwest, especially
in areas from the Hudson River into western New England,
although, some upslope clouds are not out of the question.

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
Some steady light precip will be moving in from the west prior to
daybreak on Sunday, with the best chance during the mid to late
morning hours. There continues to be some spread in the guidance
regarding the strength of a warm nose aloft and how quickly surface
temps rise above freezing. While all areas will see surface temps
below freezing to start, they should be rising thanks to the mild
southerly flow, both at the surface and aloft, especially for
southern and valley areas, as the departing high pressure area is
not in a favorable location to keep cold air locked in place. 00z
GEFS shows freezing rain or ice pellets may be the most likely p-
type at KALB during the morning hours. For now, will allow for
mainly snow at northern areas, with snow changing to snow/sleet or
sleet/rain for southern parts of the area, as the warm front crosses
the region.
For the afternoon and evening, additional precip is expected just
ahead, along and behind the cold front. P-type will transition to
either rain or snow, mainly depending on elevation. As colder air
quickly returns to the region, some lingering precip behind the
boundary may even change back to snow for valley areas before ending
as well, although some guidance is a little more uncertain in
showing if this will occur. Any steady precip is done by the late
evening, with lingering precip in the form of lake effect snow
showers for western areas. High temps on Sunday will generally
reach into the low to mid 30s for the entire area just ahead of the
boundary.
