Here's a look at the forecast details.
- Severe storms are expected from the central Plains eastward through the Midwest and into the interior Northeast.
- Clusters of storms may persist into the nighttime/overnight hours, especially from the central Plains to the Upper Midwest.
- Damaging winds and large hail will be the main threats, especially from Kansas and Nebraska eastward to Missouri. A tornado or two cannot be ruled out.
- Cities: Omaha, Nebraska | Kansas City | Indianapolis | Cleveland | Syracuse
Thursday's Thunderstorm Forecast
- Severe storms are possible from the Great Lakes to the Ohio Valley, Ozarks, and southern Plains.
- Once again, clusters of storms may persist into the nighttime/overnight hours in some of these areas.
- Damaging winds and large hail will be the main threats, but, again, a tornado or two cannot be ruled out.
- Cities: Detroit | Indianapolis | Tulsa
Friday's Thunderstorm Outlook
- A few marginally severe thunderstorms will be possible from the eastern Ohio Valley northward into the interior northeast.
- The main threat appears to be from damaging winds, but details will need to be worked out in the upcoming days on specific threats.

Saturday's Thunderstorm Forecast
- The main threat of localized flash flooding will be with thunderstorm clusters in parts of the Upper Midwest and Plains.
- The ground is most saturated right now in parts of the western Great Lakes. Any additional rainfall through Friday in these areas is likely to quickly trigger flash flooding. Parts of eastern Nebraska have also seen 2-4 inches of rainfall in recent days. Any additional rainfall could trigger localized flooding, but the heaviest rain should fall east of there.
- While the ground is not as saturated, the heaviest rain is possible from eastern Nebraska, to Iowa, extreme northern Missouri, Wisconsin, and northern Michigan. Several inches of rain may fall in a short period of time with one or more thunderstorm clusters through Friday.
