A rare roll cloud was spotted over Toronto yesterday evening. We don't normally post about weather — unless it's extreme — but given how spooky-looking these things are, I'll break that rule. Formed by downdrafts associated with thunderstorms, these clouds detach from those around them and appear to "roll" slowly around a horizontal axis. Although they look like tornadoes turned horizontal, they're not actually dangerous (nor will they suddenly turn vertical).
Nevertheless, they're damn cool looking. That is all.
Update (April 24th):
Here are some very cool photos from Billybee57 on Flickr, who caught the cloud just as it arrived at Toronto's skyline.
