We had a major storm system go through our area tonight.. You could see this wide band of cloud stretching across the sky coming our way.
The view from the ground.

What it looked like on radar

We had high wind which suddenly dropped about 10 degrees in temperature (from 31 to 21, it felt quite nice!) and then the rain came! In half an hour we had 1cm of rain come down very hard with driving wind.

One local weather sensor station reported wind gusts of over 70 km/hr. At least one tornado came from this system that touched down near Guelph. (UPDATE: Final count was 8 tornadoes)
