Since TWISTERS was released, we've seen a lot of interest in and heard a lot of questions about storm chasing, storm spotting and how the movie portrayed the science of tornadoes. Join us for a free webinar from the National Weather Service in Norman, Oklahoma as we dig into TWISTERS to compare how the movie portrays science with how it works in real life.

The webinar will be Thursday, August 29, 2024 from 6:30 PM to 8:30 PM CDT. It's free and open to everyone, but you must register at the link below to attend:
