Illinois and US Tornado Statistics for 2014 So Far

Illinois Tornado Statistics

So far, we have had 30 tornado reports in Illinois for 2014*, according to initial reports from the NOAA Storm Prediction Center. Nearly half of those were from the tornado outbreak of February 20th. Our five-year average is 59.

*Of course, 2013 was a quiet year until the November 17th outbreak that struck Illinois.

Normally, our core tornado season is March-June with about two-thirds of our tornadoes occurring then. This year was very quite during that period, I think in part due to the colder spring weather. Here is the tornado count by month:

  • January: 0
  • February: 14
  • March: 0
  • April: 4
  • May: 2
  • June: 2
  • July: 0
  • August: 0
  • September: 0
  • October: 7

Here are the event reports from the National Climatic Data Center through the end of July. This database contains some edits to the initial data from the Storm Prediction Center so the totals may not line up between the two sources.

Here are the accumulated annual tornado totals for the past 10 years for the US. Right now we are at 998 tornadoes through October 27 (black line on graph). That puts us below average and on track with 2005 and 2012. Interestingly, those two years saw drought problems in the Midwest and the Plains states. Source: NOAA Storm Prediction Center.
