Storms could roll into parts of the Chicago area as temperatures rise Tuesday.
The National Weather Service initially issued a tornado watch for most of northern Illinois, but it was canceled in all but Bureau and Putnam counties in north central Illinois, where the watch remains in effect until 9 a.m.
A line of scattered thunderstorms was moving through western Illinois and southern Wisconsin about 4:15 a.m. after a batch of storms earlier Tuesday morning that brought damaging winds and heavy rainfall to parts of the Chicago area, according to National Weather Service meteorologist Amy Seeley.
An “unstable” warm air mass was expected to keep the storms moving into the area through the morning, with scattered showers and thunderstorms likely, Seeley said.
Temperatures are forecast in the upper 80s, with heat index values rising as high as 95 degrees in areas south of Interstate 80, according to the weather service.Tags: weather
