Those tornadoes that hit the midwest...aren't they unusual this time of year?
Let me preface this answer by saying, overall, it was a 'slow year' for tornado activity. November tornadoes aren't unheard of, but are most common along the Gulf coast region, as far north as Tennessee. So the tornadoes were unusual simply because of their placement over the lower Great Lakes. Early estimates (and we're awaiting field studies to confirm the exact number) suggest 70 to 83 separate tornadoes, as strong as an EF-4 (one of the Illinois twisters). Prior to this outbreak, the worst November tornado day was November 10th, 2002 with 51 tornadoes. So this could also set a new record for November tornado outbreaks!
