The NWS said the Saturday tornado, which touched down in Dyer and Schererville, was classified as an EF-0 with winds of 65 to 85 mph. On the same day, another EF-0 tornado touched down just across the state line in Crete, the NWS said. On June 21, the NWS reported an EF-0 tornado in the South Haven area.
