[PREVIOUS STORY]

CHICAGO — Storms are headed toward the Chicago area and they may bring a risk of a tornado.

The city and surrounding suburbs are under a slight risk (2 out of 5) for the chance of severe storms. The area is likely to see those severe storms around 4 p.m. to 8 p.m. They bring with them heavy winds and a risk for a tornado.

Around 1:30 p.m., the Storm Prediction Center gave an 80% chance that a Tornado Watch will be issued by 2 p.m. Peeks of sun have emerged and the atmosphere is destabilizing.

While the forecast calls for some potentially severe weather, the threat Saturday morning is slim to none. A few scattered thunderstorms are possible, but will more than likely be far from severe criteria. 

That changes in the afternoon around 2 p.m. to 3 p.m. Thunderstorms start to move back into our area affecting the far western and southwestern suburbs to start. The threat for the City of Chicago and inner suburbs is closer to the 4 p.m. to 8 p.m. timeframe.

Northwest Indiana can expect the severe weather potential between 6 p.m. and 10 p.m. The main threat is from large hail and strong gusty winds, though there remains slight chance of  tornadoes during this time period. 

After 10 p.m., the front will have passed to the east and the threat of severe weather should conclude before midnight for the area, though it will remain gusty overnight.
