The snow will begin as a rain mix before transitioning to all snow. Wind gusts up to 35 MPH could produce blizzard-like conditions Sunday night within the heavy snow band. There will be a sharp cutoff on the northern edge so even the SMALLEST of storm track changes could make a BIG difference.

The storm exits into Michigan Monday where more heavy snow is likely.
