A severe storm system swept across South Dakota as parts of the Midwest brace for a bout of bad weather Saturday afternoon into the evening. The storm lashed southern South Dakota with high winds gusting up to 67 mph and hail, said Dale Eck, director of the global forecast center at The Weather Channel. High winds were responsible for damage across the states, Eck added, including blowing the roof off a church in Corsica, South Dakota, about 110 miles west of Sioux Falls. The storm also dropped baseball-sized hail across that same area. A severe thunderstorm watch is in effect until 3 p.m. CT for parts of South Dakota, Nebraska and Iowa as the system moves to the southeast.
Into the afternoon and evening, the storm’s energy will move through the jet stream toward central Illinois and Indiana, where severe thunderstorms are expected to form, Eck said. That storm is likely to carry its own damaging winds and dump hail from eastern Nebraska to the Ohio Valley, with the added possibility of tornadoes, some of which may be severe. Overnight, the storm will move east and southeast, threatening the East Coast with possible hail and tornadoes Sunday.
