November tornadoes seem out of place in Illinois. But weather statistics show they're not uncommon. Illinois State Climatologist Jim Angel studied the years 1950 to 2010 and found nearly 70 tornadoes occurred in November. That's more than October or December.
But what made Sunday different was the outbreak that occurred.
"All our other outbreaks tend to happen in the springtime," Angel said. "So the ones in November tend to be single events, but this is by far the biggest number that we've seen in November."
