The Chicago metropolitan area is bracing for severe thunderstorms on Tuesday, with tornado and flood watches issued for various parts of the region. These conditions are set by the warmest and most humid air experienced in over six months.
A tornado watch specifically covers DeKalb, Kane, Lake, McHenry, and La Porte counties as the storms approach. Officials have warned that tornadoes are possible as the weather system passes through the area.
In response to the thunderstorms, a ground stop has been put into effect at Chicago's O'Hare International Airport. This is a developing story and will be updated as details emerge.
