National Weather Service Northwest Indiana says there was a confirmed tornado that touched down in central Illinois and caused damage.
Storms should flare up in Illinois and eastern Missouri and move into Indiana. The storms could move quickly and produce strong winds and tornadoes.
Here is the text of an Associated Press article that moved this morning:
A number of Midwestern states woke up Sunday to the threat of intense thunderstorms and even tornados, with officials raising concerns that people — including fans heading to some NFL games — might be caught off guard by such severe weather at this time of year.
"People can fall into complacency because they don't see severe weather and tornados, but we do stress that they should keep a vigilant eye on the weather and have a means to hear a tornado warning because things can change very quickly," said Matt Friedlein, a meteorologist with the National Weather Service.
According to agency officials, parts of Illinois, Indiana, southern Michigan and western Ohio are at the greatest risk of seeing tornadoes, large hail and damaging winds throughout the day Sunday. Strong winds and atmospheric instability were expected to sweep across the central Plaines during the day before pushing into the mid-Atlantic states and northeast by evening. Many of the storms were expected to become supercells, with the potential to produce tornadoes, large hail and destructive winds.
In Chicago, the Office of Emergency Management and Communications issued a warning to fans attending making their way to Soldier Field to watch the Chicago Bears host the Baltimore Ravens. It urged fans "to take extra precautions and ... appropriate measures to ensure their personal safety."
