CHICAGO -- The National Weather Service cancelled a Tornado Watch that had been issued for most of the Chicago area Saturday evening.
A Flash Flood Warning is also in effect for McHenry and Lake counties until 10 p.m.
Severe thunderstorms have developed southwest Wisconsin earlier Saturday. Those storms developed across the watch area through the afternoon, feeding on upper 70-to near 80-degree dew point air.
Thunderstorms burdened the Chicago area during the mid-afternoon hours, with Cook and Lake Counties under a Severe Thunderstorm Warning until about 4 p.m.
The weather also caused a temporary evacuation in Union Park. But by 5:30 p.m. the storms had subsided and attendees went back in.
Commonwealth Edison says it has about 16,000 customers without power due to the weather. Most customers are in the Libertyville and Chicago North Side areas and the company says it is preparing about 80 extra crews.
Customers are encouraged to call 1-800-Edison-1.
