ABC7 meteorologist Jaisol Martinez said the damaging winds, hail and frequent thunderstorms were the biggest threats in any developing storm.
A thunderstorm is expected between 7pm and 12am. The main area of concern is southwest Chicago, Martinez said. The storm will be moving northeast at around 40 mph.
The Hurricane Prediction Center has most of Chicago under “marginal” severe weather risk, level 1 of 5. The far southwest suburb is in the “mild” risk category, level 2 of 5.
Additional storms are possible in the evening through Sunday, but are not expected to become too severe.
Then, big changes will occur on Sunday. We'll see the warmest weather in the morning, with high temperatures around 60, before cooler weather brings windy conditions and possibly mixed rain/snow on Sunday evening.
Sunday night's low will be around freezing.
