Thunderstorms are expected to rumble through the Windy City and other parts of the Midwest Friday. Some storms could be strong with gusty winds, hail and brief downpours.

In addition to Chicago, areas from Wisconsin to Missouri, including Milwaukee, St. Louis and Kansas City, are in the threat area.

The time period of concern is this afternoon and into the evening. The afternoon rush hour could become treacherous in spots across the large metro areas.

The most intense thunderstorms can bring wind gusts to 50 mph, hail and brief downpours. These downpours will reduce visibility and bring the risk for hydroplaning.

Some minor tree damage is possible in spots along with localized power outages. Localized flash flooding in low-lying and poor drainage areas is also possible.

The culprit of Friday's active weather is a cold front associated with an area of low pressure. This is the same storm storm system that brought potent thunderstorms from Wisconsin to Nebraska on Thursday.

After showers and storms clear the region, an unseasonably cool air mass will settle over the Midwest Saturday with high temperatures only reaching the 60s and 70s.

Temperatures over the weekend will average 5 to 15 degrees below normal across the Great Lakes and Midwest. Many record low temperatures could be matched or broken Saturday and Sunday.
