Miami Valley , Whitewater Valley, and the I-71 corridor of Ohio/Indiana:
Hazardous Outlook: Very warm moist air will move into the region ahead of a strong arctic front. Initially rain will develop late Thursday and last into Thursday night as the front begins to move in. As the front slips Southeast temperatures will begin to drop into the 30s and eventually 20s Friday evening and night. As this happens another low pressure will move up along the front. The exact track and speed of the low will determine how much ice/snow the region will see. Current thinking is that rain heavy at times Thursday night will transition to a mix by dawn Friday then to over to light snow Friday afternoon and lasting into early Friday night with significant icing and some snow accumulation by Saturday morning. Exact amounts are still up in the air. Stay tuned for further details.
