Severe Weather in Illinois in 2011

According to preliminary data from the NOAA Storm Prediction Center (SPC), in 2011 Illinois has received:

  • 55 reports of tornadoes
  • 247 reports of hail greater than 1 inch in diameter
  • 474 reports of wind damage

So it has been a fairly active year for severe weather in Illinois. Fortunately, we have not experienced the level of devastation as was seen in the Southeast or in Joplin, MO.

Personally, the outstanding feature of this year is hail. I’ve had pea-sized hail at my house four times this year (including last night at around 1 am). That’s unusual for me because I’ve gone for years at a time without seeing any hail at home. Out of curiosity, I pulled up the hail statistics since 2000 for Illinois from the SPC site. Beginning in 2011, they changed the significant hail criteria from three-quarter inch to one inch so any hail report less than one inch will no longer be counted.
