Tornado Confirmed In Kane County: National Weather Service

ILLINOIS — An EF-0 tornado with peak winds of 80 mph was confirmed in Kane County on Saturday, the National Weather Service said.

The path of the tornado that hit close to Big Rock was nearly four miles, according to NWS. The tornado downed trees and tree limbs, damaged the roof of a barn and snapped at least one power pole.

Big Rock is about 15 miles west of Aurora.

The National Weather Service said it expects to release more information about Saturday's damaging winds later in the day. More than 26,000 ComEd customers in the Chicago area were without power Saturday as high winds hit the area, CBS reported.

Temperatures will get colder Monday and Tuesday in the Chicago area, with highs in the 50s, then will warm up to the high 60s or low 70s for Wednesday and Thursday. By the end of the week, though, unseasonably warm weather will end as "a pattern change is coming ... with plunging temperatures," including highs in the 30s and lows in the 20s, according to the National Weather Service.
