Areas affected...Parts of southwestern NY and northwestern PA

Concerning...Snow Squall 

Valid 220314Z - 220545Z

SUMMARY...A snow squall will continue tracking eastward across parts
of southwestern New York and northwestern Pennsylvania during the
next few hours.

DISCUSSION...A snow squall has recently organized/intensified as it
moves eastward out of Ontario Canada. As the squall passed over
KBUF, visibility dropped to 1/8 mile with a 28-kt gust. As ascent in
the left-exit region of a robust midlevel jet streak continues
overspreading western NY, the snow squall will continue tracking
eastward along an associated surface winds shift during the next few
hours. Around 40-45 kt of west-southwesterly flow in the lowest 1 km
AGL (sampled by regional VWPs) and modestly steepened low-level
lapse rates will continue to support strong gusts and visibility
reductions of 1/4 mile or less in bursts of heavy snow.
