Stuck inside all day, no tornadoes hit me lol. But the rain was unreal. Flooded my garage worse than ever. Radar has looked pretty intense at times.

in london ontario today. I live in the southwestern part of the city... the clouds were scary. like really dark and greeny color.. but no lightning or thunder.. brief rain for a couple of minutes, some little hail.. then poof gone.. the clouds were the highlight.

Was at Canada's Wonderland on Saturday when the tornado warned storm hit. Wasn't severe in terms of wind and there was no hail, but it sure rained a ton.

By the way, roller coasters are a fantastic way to spot far away storms! Was also there yesterday and there was a storm over Newmarket with some amazing structure. There was definitely a shelf cloud on it, but I wonder what else was there was that I couldn't spot in time. I checked the radar after and there appeared to be a hook echo. Was anyone keeping an eye on that storm? I think it happened between 4-4:30.
