Multiple rounds of storms are expected on Wednesday, with severe storms expected mainly during the afternoon and evening. These storms will quickly become severe, initially capable of producing large hail to 2+ inches in diameter. As storms become more linear later in the afternoon and evening, the threat for damaging winds will increase, with some gusts potentially to 75+ mph. Tornadoes will be possible, some potentially strong (EF2+). Localized flooding is also possible if storms repeat over the same areas. Ensure your severe weather shelter is accessible and that you can receive weather warnings, and consider adjusting any outdoor plans.
There may be a window for severe storms to develop across mainly northeast Iowa and southwest Wisconsin early Thursday afternoon. Whether this threat materializes will depend heavily on how storms evolve Wednesday afternoon. The severe weather risk would quickly depart by mid to late afternoon.
With the risk for a potentially significant severe weather event looming for tomorrow afternoon, now is the time to dust off your severe weather preparedness plan. Double check your that your safe places are accessible, make sure your phone can receive weather alerts, and be prepared to adjust any of your plans.
