Following a couple of days of locally heavy, gusty thunderstorms in parts of the central and eastern United States, the risk of violent thunderstorms will increase over part of the Midwest on Wednesday.
Big storms will likely erupt over the western part of the Dakotas and eastern Montana, as well as parts of Iowa, during Tuesday and Tuesday night.
Some of the storms that develop and drift southeastward will have the potential to threaten lives and cause property damage from portions of Iowa to parts of Illinois, Indiana, Ohio, Wisconsin, Michigan, Kentucky and West Virginia during Wednesday.
Exactly which portions of these states will be hit the hardest will depend on the track of a storm system originating from the Northwest and where the boundary of hot, humid air versus cooler, drier air sets up.
"During Wednesday and Wednesday night, the greatest and most widespread threat from the storms will be damaging wind gusts and flash flooding," according to AccuWeather Meteorologist Brandon Zapolski.
"However, some of the storms will bring the potential for large hail," he said.
A few tornadoes could also be spawned from some of the strongest storms.
Where the storms enter metro areas or approach major airports, significant disruptions to travel may occur.
From Wednesday to Wednesday night, cities that could be hit by severe thunderstorms include Des Moines, Iowa; Chicago and Peoria, Illinois; Milwaukee; Indianapolis and Fort Wayne, Indiana; Cincinnati and Columbus, Ohio; Louisville, Kentucky; and Huntington, West Virginia.
Cleveland Cavaliers fans heading to celebrate with the team during the NBA championship victory parade on Wednesday should stay alert for storms.
