Most severe weather I've ever experienced was in Ponca City at a local motel. The rain was so heavy that I couldn't see beyond the parking lot and it was at about a 45-70 degree angle from the wind. I took a video from the doorway. That was some downpour.
I recall one that hit the main Stillwater campus with baseball sized hail. It destroyed or severely damaged vehicles all over the campus. The guy I worked for was the college VP for Research and Technology Transfer. He said a hail ball came through his office window and landed on his secretary's desk. Yikes.
