The severe weather won't be as widespread as last Friday's outbreak, but it could still produce dangerous conditions in parts of Illinois and Indiana, as well as parts of surrounding states.

A powerful low-pressure system is likely to spawn a dangerous outbreak of severe thunderstorms in portions of the Midwest, South and East, where tornadoes, widespread damaging winds, large hail and flash flooding are all concerns.

Tens of millions of people living in the Midwest and central U.S. could be impacted by tornadoes on Wednesday while critical wildfire conditions continue to impact the Southwest, after recent wildfires and a tornado outbreak killed at least 42 people over the weekend.
