.SYNOPSIS...
Clouds gradually clear tonight giving way to a chillier night.
Expect abundant sunshine tomorrow with seasonably cool
temperatures and a slight northerly breeze. Sunshine on Saturday
will slowly fade behind increasing clouds late Saturday into
Saturday night. Our next disturbance arrives Sunday into Sunday
night resulting in a period of snow and light snow
accumulations which may give us slippery travel conditions.

.LONG TERM /SUNDAY THROUGH THURSDAY/...
Confidence continues to increase on a precipitation event Sunday
into early Monday as upper-level energy and a weak surface low track
eastward across the area from the Upper Great Lakes/Ohio Valley
region. The actual track of this feature remains a bit uncertain and
will depend on its interaction with a surface high located to its
north and a strong vertically stacked low pressure system near
Labrador. Still, confidence is highest for precipitation to occur
for areas along and south of I-90 and across the southern
Adirondacks with lower confidence elsewhere. Temperatures profiles
will favor precipitation starting as snow or a mix of rain and snow
on Sunday transitioning to all snow Sunday night as wet-bulb
processes and dynamic cooling gradually drop surface temperatures
to and then below freezing. Where it does snow, a light accumulation
of snow is anticipated, even in the valleys. The higher snowfall
amounts (possibly reaching advisory levels) look to be across the
higher elevations.
This system quickly departs out to sea on Monday with surface high
pressure returning with a period of dry weather for the first part
of the week. A large storm system which will develop across the
central CONUS early in the week will gradually shift eastward,
increasing precipitation chances for the end of the week.
