   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.
