Severe storms that pelted the Omaha, Nebraska, area with hail are expected to move east Wednesday and hit parts of the Ohio and Tennessee valleys, CNN meteorologist Sherri Pugh said. Nashville; Louisville, Kentucky; and Cincinnati probably will be pounded with heavy rain and strong winds Wednesday night, the National Weather Service said, with the chance of precipitation at 70% to 80%. Isolated tornadoes and flash floods are possible, Pugh said, though the threat is lower than it was Tuesday. But the hail was what got everybody’s attention in Nebraska, pummeling 4,300 vehicles at Woodhouse Auto Family in Blair, about 30 miles from Omaha.
