  1. We just had our first tornado touch down in New Jersey. This was scary and the damage it left behind wowwwww wowwwww wowwwww 🤦🏻‍♀️. I've never seen anything like this in my life ….

  2. Spann the Man! You've been my hero ever since you told the people in a Haleyville trail or park not to wait, but to take shelter. "Go Now!"
    That was quite a few years ago. You saved many lives that night by trusting your instincts, and doing the job you were called to do.
    You will always be a hero to me. ❤️
    God bless and keep you and yours.

  3. I'd love to see an updated presentation. I'm under the impression that there's been groundbreaking data collection and compelling computer modeling that has refined our understanding of tornado formation since this was made. The fundamentals might not have changed, but added detail would be interesting.

  4. Tornado: E X I S T
    Me:When Did Air And Dust Form
    Friends:LOOK A PRETTY SWIRLING GREY THING
    FRIEND 2:LETS GO IN IT
    Me:I WILL RECORD US GOING UP
    Friends:Can't Wait To Fly
    Me: Same

    The End (We All Died
