Areas affected...Northeast Ohio...northwest Pennsylvania...western
New York

Concerning...Snow Squall

Valid 292014Z - 300015Z

SUMMARY...Snow squall conditions are possible as a secondary cold
front moves off of Lake Erie. Moderate to briefly heavy snowfall and
strong wind gusts will lead to reduced visibility with this
activity.

DISCUSSION...A secondary cold front is moving through the Great
Lakes region as a potent upper low continues through southern
Ontario/Quebec. A coherent band structure has develop as the front
has approached Lake Erie. This band is expected to move onshore and
progress into Ohio/Pennsylvania/New York. Moderate to briefly heavy
snowfall may occur with this activity. Strong cold advection has led
to steep enough lapse rates in the boundary layer which could could
contribute to enhanced wind gust potential above what has already
been ongoing synoptically this afternoon.
