February 27 More severe weather was forecast for February 28, although the threat area was initially poorly forecast. A 15 percent risk area was initially outlined for eastern Kentucky and eastern Tennessee on February 24. The outlined area was given a slight risk the next day, thought weather data models began to show that ingredients for severe weather were shifting farther north towards the Ohio Valley region. The slight risk was then shifted northwestward twice the subsequent day at both day 2 outlook times. By the time the day 1 outlook was issued, the slight risk covered much of the Ohio Valley. While only moderate instability was in place, very strong wind shear and a discrete convective mode close to the surface low brought the possibility of both damaging winds and a few tornadoes in this area, with a 5% tornado risk area in place for much of Ohio, and a 2% tornado risk present farther west across Indiana and Illinois.

In Ohio, another high-end EF1 tornado caused considerable damage to homes, trees, and outbuildings in and around Jacksonburg. An EF0 tornado overturned mobile homes and damaged abandoned farm structures at the Pickaway Correctional Institution near Orient.
