 Iowa, Illinois into the afternoon and then continue south and east to Michigan, Indiana, and even western Ohio tonight. These storms will have the potential for heavy rain, damaging winds, hail, and even a tornado. Another region where heavier thunderstorms will be a risk is across the northeast from New York and Pennsylvania into southern New England and parts of the mid-Atlantic. These storms can produce drenching downpours as well as damaging wind gusts. Before the thunderstorms develop in the east, it will be a hot day for New England into the mid-Atlantic into the Tennessee Valley.
