Iowa, Illinois Special Weather Statement - Moderate | Effective 06/08/2026 11:20

Locally heavy rainfall rates in excess of one inch per hour will be seen with the numerous showers and scattered storms this afternoon across far eastern Iowa and northwest Illinois. These rates are likely to result in minor flooding, especially over urban or poor drainage areas, along with those locations that saw heavy rainfall on Sunday. In addition, conditions are favorable for the development of funnel clouds, and possibly brief, weak tornadoes. The National Weather Service will continue to closely monitor the situation, and may issue a Tornado Warning if the threat increases. If you see a funnel cloud or tornado, seek shelter indoors and then contact your local law enforcement agency for relay to the National Weather Service.
