Oh man, I hope I never have to find out. We drove through Joplin, MO right after the EF5 there, and that cured me of ever wanting to storm chase. I felt like throwing up. I have also seen tornado damage in Moore, OK. Those things are scary.
Interestingly enough, I nearly drove into one last year. I left work to try and beat a severe thunderstorm to my house. I wanted my car in the garage! Well, while I was driving the 22-miles, the storm went tornadic. My phone kept giving me alerts and luckily I looked down and saw 'tornado alert.' So I brought up my radar app, and there was a rain wrapped tornado directly in front of me. I did a 180 without stopping and drove back to a grocery store I had just passed. They unlocked the door and told me to go to the freezer. I joined several others back there. Luckily it missed the store. I know you should not use a cell phone and drive, but all bets are off in a tornado, lol.
That tornado was only an EF1, but the wind field was incredible. It flipped a semi on the interstate approximately a quarter-mile
from where I turned around.
My house is 2 mi N of Elgin, the grocery store was in Elgin, OK. This is the radar image from my phone. So, I nearly drove into a tornado and technology saved me. That was on April 29, 2016. It blew most of the metal furniture off my back porch, but my house had no damage. It did trash a lot of my potted plants unfortunately.
