In addition to cloud-to-ground lightning and heavy downpours, the National Weather Service said the strongest storms may produce hail up to 1 inch in diameter. That's large enough to dent the siding on your home.
The greatest threat for large hail appears to be along and south of the I-80 corridor in the south suburbs and northwest Indiana.
The ABC7 AccuWeather Team is also tracking slushy wet snow accumulations that are possible late Friday into Saturday.
