‘Weather is cool’: Weird Chicago weather, from northern lights to water spouts

Thanks to the powerful force that is Lake Michigan and the urban heat island that is Chicago, the city has witnessed some unusual and extreme weather events. Last episode was about lake-effect snow and a phrase you hear all the time: “Cooler by the lake.” But Chicago weather definitely gets stranger than that. We’re talking thundersnow, water spouts and even space weather. Why do these weather events happen, what makes them unusual and how can you have a little fun (safely!) when they come around? We talk with Jeff Frame, a teaching professor in the Department of Climate, Meteorology and Atmospheric Sciences at the University of Illinois Urbana-Champaign.
