"A surge of warmer air and moisture moved eastward across parts of the Midwest and into the Ohio Valley on Saturday morning," weather.com meteorologist Linda Lam said. "However, some colder temperatures remained closer to the surface which resulted in some freezing drizzle and freezing rain."

According to Lam, freezing rainfall totals were generally less than a tenth of an inch across the region, but those low totals still caused some serious travel impacts.
