The Alberta prairies don't really get the extremes others experience, at least not near the cities or within my lifetime. There's tornadoes here of course but the colder climate usually neuters them. Sometimes they take out a trailer park or threaten towns closer to the rocky mountains. Top 5 most snow on record last year so I had to finally get a snowblower which roomy and I found one non-working for free and fixed it up. Blizzards, wind storms, fog. That's about it unless forest fire smoke counts as weather.

That's pretty boring so, I'll retell my dad's. My dad saw the F4 class tornado of August 1987 up close at the chemical plant he worked at the time. In Edmonton, Alberta that day was called Black Friday. No relation to the shopping slop day. According to him they didn't really know what they were looking at as it tore by the plant nearly hitting them and saw it reach the outskirts of the city, throwing debris everywhere. He remembers the sound it made vividly. Creepy howlng sound, and the sky was full of boiling green dark clouds.

I've seen those boiling dark green clouds once myself in 2014 or so but besides looking very disturbing, no tornado that time. It's strange, I watch videos of tornadoes in the USA but I guess the boiling clouds don't capture well on video or they're just different idk. If you know of Styropyro the mad scientist, he has a second channel where he chases tornadoes I've been watching.
