Large sections of Ohio and Kentucky were contending with the most serious risks, along with a stretch of far-eastern Indiana. The Storm Prediction Center's most recent severe weather outlook ranked threats in parts of those states at Level 4, of five levels, just before 12 p.m. CDT. Level 4 corresponds with "moderate" on that scale. Much of Kentucky and southern Ohio received that warning, including major cities like Cincinnati, Columbus, Dayton, Lexington and Louisville.
