Areas affected...Central Indiana to Western Pennsylvania

Concerning...Heavy snow=20

Valid 251500Z - 251800Z

SUMMARY...Moderate to heavy snow rates to continue through the
morning.

DISCUSSION...A broad zone of isentropic ascent and frontogenesis
across the Ohio Valley continues to support a widespread region of
moderate snowfall this morning. Within this broad zone, heavier
bands of snow with rates of 1+ inches per hour are being observed.
This appears to be near the corridor of maximum 700mb frontogenesis
based on SPC mesoanalysis. The peak of this frontogenesis appears to
be from near Dayton, OH to Pittsburgh through 18Z before weakening thereafter.=20

This also corresponds to a narrow zone 50 to 100 miles north of the
sleet/snow transition zone which based on KILN Correlation
Coefficient seems to have stalled southeast of I-71.=20

Expect this zone of heavier rates to continue through the morning
before weakening by early afternoon as the primary storm system
shifts farther east and frontogenesis weakens.
