Friday severe risk upgraded to Moderate

The Storm Prediction Center has put out a "moderate risk" of severe weather for most of Illinois during the day on Friday.

This severe risk comes with two batches. First, severe storms across Nebraska during Thursday evening will group together and form a complex of strong storms during the late-night hours over Iowa. This complex will move into Illinois during the early morning hours. There is a slight risk that some storms could produce damaging straight-line winds and torrential rainfall.

Should skies clear (even for an hour or two) during the late morning hours on Friday, severe storms will become likely. Main threat with afternoon storms will include large hail, damaging winds, and isolated tornadoes.

We'll have to wait and see what happens after the morning complex to determine our risk of severe here in the Rock River Valley. Stay tuned!
