Chicago, Illinois – Illinois residents should brace for intense heat and humidity starting this weekend, with “feels like” temperatures surpassing 100°F for several consecutive days, especially across central and northern parts of the state.
According to the National Weather Service in Chicago, heat index values will begin rising Saturday, June 22, and may linger into midweek.
