Severe Weather Events

The Midwest and Great Lakes regions faced severe weather, including damaging winds, large hail, and the possibility of tornadoes. These conditions led to flash flooding concerns in areas like North Dakota, Minnesota, and parts of the Ohio and Tennessee Valleys. (makensweather.com)
