CHICAGO (AP) — Severe weather forced the Lollapalooza music festival on Chicago's lakefront to end a half-hour early Sunday night. Lollapalooza organizers say they made the decision after the National Weather Service and six onsite weather monitors predicted strong storms with possible lightning. Florence and the Machine, Bassnectar, Kygo and NERO shortened their sets and more than 89,000 fans exited Grant Park. Earlier Sunday, the festival evacuated at 2:35 p.m.
