This week, LPM’s Bill Burton talks with Tawana Andrew about different types of thunderstorms. Tawana Andrew: Good morning, and today's topic is all about thunderstorms. BB: It is that magical time of the year where thunderstorms can pop up seemingly out of nowhere. There's different kinds of thunderstorms, too. Some of those stronger summer storms are pulse thunderstorms, which is a type of single-cell storm.
