.NEAR TERM /THROUGH THURSDAY/...
As of 122 PM EST Wednesday...The bands of snow are showing up
quite well on MRMS radar and have started to deteriorate across
the North Country. Still think there`s a window where we may see
briefly heavy snow showers but I`m with the latest trends in the
HRRR and RAP the potential for actual snow squalls is starting
to fade. There`s still some modest instability expected over the
Northeast Kingdom so at this point the best chance for any
squalls to develop would be along the international border in
Vermont. Northwest winds have already picked up at MSS so the
front strong cold air advection isn`t that far behind and indeed
several sites just west of Ottawa are already in the teens so
cold air is on the way for this evening.

Previous Discussion...South southwest winds ramping up this
morning along with warm air advection ahead of approaching cold
front so have continued with mention of freezing drizzle through
the morning hours. Will have some modest low level instability,
therefore potential for some snow squalls as the front crosses
the area. Best dynamics will remain to our North closer to the
low pressure center. A dusting to two inches of snow is
expected, especially across our most Northern zones. Will see
some strong gusty winds today ahead of and just behind the cold
front. Cold air returns for Wednesday night and Thursday behind
departing arctic cold front. Overnight min temps will drop into
the single digits and teens below zero, followed by an
unseasonably cold day for Thursday with high pressure regaining
control of the weather pattern. Temps on Thu will be in the
teens and single digits across the area.

...Snow showers with embedded snow squalls expected this afternoon...

Web cams and current radar trends show snow showers with embedded
snow squalls continuing to develop across the eastern Adirondack
Mountains and parts of central and northern Vermont. Any snow
squalls will be accompanied by brief heavy snow, gusty winds, and
sharply reduced visibilities. These conditions will produce
localized very hazardous driving conditions during the afternoon
and evening commutes. Motorists should exercise caution and be
alert to rapidly changing weather conditions. The threat will
quickly improve after sunset tonight.

I was wondering if someone will take the time to start this.

The NAM has been showing some pretty decent snows especially for western PA.

Yikes! Maybe these are the reason they've brined I-84 here this afternoon!

Northern VT saw some squalls move through today with flurries flying much of the day.  It was just enough new snow to whiten up the snow on the ground.  The wind has picked up this evening so it is blowing the new snow around.

Slowly fading through the region, maybe @MaineJay gets a late flurry.

I saw six flakes on my drive home, but sublimation from the cold, dry air will mean a net loss in snowcover. :classic_laugh:
