Chicago weather

National Weather Service officials are expecting dangerous swimming conditions at the shores of Lake Michigan, as well as a risk of thunderstorms Saturday in portions of north central and northeast Illinois, and northwest Indiana.

Weather officials said there is a slight chance of rain Tuesday as temperatures were expected to hit 80 degrees.

The National Weather service will continue to look for signs of tornado damage following wind speeds above 60 miles per hour last night. Meanwhile, thousands of Chicago residents remain without power.

Powerful thunderstorms with potentially damaging winds were expecting to move through the weather-fatigued Chicago area Friday evening.

A heat advisory that was issued Wednesday for most counties south of I-80 is expected to expand north Thursday, including most of the Chicago metro area, said the National Weather Service's Scott Baker.

The last time O’Hare International Airport, Chicago's official recording site, experienced a temperature of 100 degrees or higher was July 6, 2012.

Severe thunderstorm warnings spread across the Chicagoland area.

The National Weather Service said that the line of thunderstorms could produce heavy local rainfall, frequent lightning and some strong wind gusts.
