Thunderstorms continue to the southeast across the Chicago Metro area and are headed into northwest Indiana, currently in a weakening phase

The thunderstorms moving through the Chicago area are weakening a bit as they encounter slightly cooler and somewhat more stable air, a result of today’s lake-effect cooling.   While still potent, the storms may stay just below severe levels and additional warnings may not be required after the one remaining severe thunderstorm warning currently in effect for portions of Cook, Du Page, Grundy and Will counties until 10:15 pm
