A brief, violent storm swept through the Chicago area Sunday afternoon, leading to one death and an evacuation of Lollapalooza, and more storms could be heading this way in the evening.
Following temperatures in the low 90s, a cold front is expected to pass through in the evening, bringing another chance for thunderstorms and heavy rain. The best chance for the second round of storms will arrive after 7 p.m., and most of them should move out of the Chicago area by midnight.
More severe thunderstorms, with heavy rain, large hail and damaging winds, could strike again between 7 p.m. and 11 p.m. in all of the Chicago area and Northwest Indiana.
Sunday's afternoon storm saw winds up to 60 mph and golf ball-sized hail in some parts of the region.
In west suburban Wood Dale, a man died and several others were injured after a tent collapsed at the Wood Dale Prairie Fest. A dome at a ballpark in Rosemont also collapsed, but no one was injured in the incident.
Lollapalooza was evacuated briefly due to the severe weather as well, but all shows were rescheduled. If severe weather strikes again Sunday night, the festival could be evacuated for the second time this weekend.
The rest of the week looks much cooler and drier, as temperatures drop into the 70s. Over the course of the week, the area could experience a 20-degree temperature drop, from a high of 92 degrees Sunday to a predicted high of 72 degrees Saturday.
There are no thunderstorms in the forecast for the remainder of the week, but there is a chance for showers on Thursday.
