Upton already all in for down here
Upton all in
Given the supply of low level cold air and unlikelihood of
warmer air intruding aloft, this event looks to be all snow for
just about the entire region, except maybe the south shore of
eastern Long Island for a time. Too early to get into the
mesoscale details here, but confidence in significant snowfall
amounts over 6 inches continues to increase, with potential
for over a foot of snow in areas that experience the best
mesoscale lift and snow growth NW of the low track.
NE winds should also be quite strong along the coast due to the
pressure gradient between the strong high to the north and the
developing low, as high as 25-35 mph with gusts up to to 45
mph, causing considerable blowing and drifting of snow and at
least near blizzard conditions.
Still some question how quickly the low will pull out on Thu,
with the ECMWF lagging a little behind the GFS, so steady snow
still likely in the morning, then gradually tapering off from W
to E through the day.
Fair and cold Thu night into Sat with high pressure returning,
then some moderation possible with an approaching frontal
system. Too early to get into precip type details with this
system, just calling it mainly rain/snow at this juncture
