   Areas affected...eastern OH and western PA/NY

   Concerning...Snow Squall 

   Valid 171600Z - 172000Z

   SUMMARY...Snow squalls are likely to accompany a cold front pushing
   east across eastern Ohio into western portions of Pennsylvania and
   New York through this afternoon.

   DISCUSSION...Low-topped convection has recently increased along a
   cold front progressing through north-central/northeast into central
   Ohio. Both KLPR and KOSU sampled a visibility reduction to
   quarter-mile with gusts of 30 and 31 kts respectively, and KMFD
   recently dropped to quarter mile as well. The more organized portion
   of the snow squalls will probably be confined closer to Lake Erie,
   where stronger low-level convergence is anticipated. Steep low-level
   lapse rates along/ahead of the front are the primary driver of a
   favorable thermodynamic environment with SPC Mesoscale Analysis
   estimates of a 2-4 Snow Squall Parameter. This is expected to shift
   east with the front, favoring snow squall production throughout the
   afternoon.
