Areas affected...Pennsylvania into western New York

Concerning...Snow Squall=20

Valid 191650Z - 192045Z

SUMMARY...Occasional visibility reductions associated with
moderate/heavy snow showers and gusty winds may spread east across
parts of Pennsylvania and into western New York through the
afternoon.

DISCUSSION...A cluster of snow showers migrating across eastern OH
and western PA over the past few hours have yielded occasional
visibility reductions down to 1/4 mile per regional web cams and
ASOS observations. These visibility reductions are largely being
driven by moderate to heavy snowfall rates within shallow, but
convectively augmented, snow showers ahead of a progressive
mid-level wave evident in GOES imagery. Strong cold advection
through 850 mb will continue to support 25-35 mph wind gusts, which
will further contribute to periods of low visibility by blowing
falling snow and the antecedent snow pack in place across western
PA. As such, periods of snow squall conditions should spread
east/northeast through mid-afternoon in tandem with the upper wave
and the surging low-level cold air mass.
