SPC’s tornado threat outlook that preceded the November 17 2013 tornado outbreak. Can’t remember the last time Southern Ontario was included in an SPC moderate risk area or under such high tor probs as these… I was in Thailand, so no Ontario chasing for me, though it was a pretty big bust in province anyhow. Sadly, not so south of the border where several people were killed by damaging tornadoes, with Illinoise particularly hard hit.
