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

Concerning...Snow Squall=20

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.
