Meteorological Hazards & OutlookNational Weather Service

The Chicago NWS reports that while an earlier complex of storms has mostly dissipated, a second disturbance moving across central Iowa is expected to trigger additional development.

• Localized Flooding: Due to heavy rainfall from recent storm systems, many areas remain highly susceptible to flooding. Any thunderstorms that stall or redevelop over these already saturated regions carry a high risk of localized flash flooding.National Weather Service
• Damaging Winds: The strongest storms today are capable of producing gusty to locally damaging wind gusts between 40–60 mph. While this is a Level 1 of 5 threat for severe weather, the greatest risk is focused south of the I-80 corridor.National Weather Service+ 1
• Overnight Conditions: A backdoor cold front moving off Lake Michigan late this evening is expected to shift winds to the northeast.
