A round of fast-moving severe thunderstorms plowed through the Chicago area Sunday afternoon, producing hurricane-force winds and prompting tornado warnings in parts of Northwest Indiana. A tornado watch was issued throughout most the Chicago area and Northwest Indiana for much of the afternoon.

The Tornado Watch is in effect until 9 p.m. for dozens of Illinois counties such as Grundy, Kendall, Kankakee, La Salle and Will. Indiana counties that are under the watch include Newton, Benton, Warren and Tippecanoe, among others.
