The largest hail stone to ever fall in the state of Illinois landed in Minooka on June 10, 2015. This hail stone was 4.75" in diameter. Although this is large, the largest hailstone to ever fall in the US was 8 inches in diameter and fell in South Dakota.

#9 - RECORD RIVER FLOODING
Record rainfall led to a new high crest on area rivers on April 17-18, 2013. The western suburbs saw over 7 inches of rain, which pushed the Fox and Des Plaines River to all-time record highs. Many homes were flooded along the river with water slow to recede.

#8 - COLDEST FEBRUARY ON RECORD
February 2015 tied for the coldest February on record. You had to bundle up all month long as the average monthly temperature was just 14.6 degrees - a full 13.1 degrees below the monthly average. It also snowed a lot that month, with 26 inches of snow reported.

#7 - CHICAGO RECORD RAINFALL
Over six inches of rain fell in Chicago on July 23, 2011 - the all-time greatest daily rainfall total on record. The water flooded homes and cars were stranded across the city. The Dan Ryan was even covered with water! What made this event more remarkable was that most of the 6 inches of rain fell in just a three-hour window, which led to extreme flash flooding.

# 6 - NOVEMBER 2013 WASHINGTON TORNADO
Twelve days before Thanksgiving on November 17, 2013, over 25 tornadoes reported across the state of Illinois and 30 reported in the state of Indiana. The largest, an EF-4 tornado with winds to 190 mph, hit Washington, Illinois. It left a trail of destruction, killing one person and nearly wiping out the whole town.

#4 - MARCH RECORD HEAT VIDEO
From winter tornadoes to record spring heat, let's go back to 2012 for the record March heat wave. From March 14th to March 22nd it felt like summer, breaking or tying record highs for almost two weeks. How warm was it? For eight of those 10 days, it was over 80 degrees. That may not seem too warm, but remember that our normal high for that time of year is in the lower 40s.

#3 - JANUARY 2019 RECORD COLD

During the "Polar Vortex" between January 30 and 31st of 2019, Illinois got a new state record for coldest temperature ever recorded. The prize belongs to Mt. Carroll, with an air temperatures that dropped to -38 degrees. Here in Chicago the temperature dropped to -23 degrees! And in Aurora it dropped to 32 below zero. The temperature stayed below zero for over two days until the thaw started, and Chicago recorded its 2nd coldest high temperature ever, with the high temperature on January 30 only reaching -10 degrees.

#2 - 2015 TORNADOES
In 2015, there were numerous, violent tornadoes. Because of that, we've combined two large tornado outbreaks that happened into our Number 2 spot. The severe weather season got off to a quick start, with the first outbreak occurring in April. On April 9, 2015, 11 tornadoes touched down in Illinois. Six of these tornadoes were spawned from the same supercell, with one of those tornadoes being an absolute monster EF-4 with winds up to 200mph. This tornado was on the ground for 30 miles, from Franklin Grove to Fairdale. This tornado took two lives.

One of the 10 was rated an EF-3 and had winds up to 160mph. These winds hit both coal City and Braidwood. Thankfully, no one was killed, but 11 people were injured.

#1 - GROUNDHOG DAY BLIZZARD
The historic "Groundhog Day Blizzard" takes #1 on our list for crippling the entire region for two days in February of 2011. Who can forget the scene on Lake Shore Drive as the heavy snow shut down the drive with many stranded in their cars. People boarded CTA buses to stay warm until they could be rescued. Winds along the lakefront gusted to 70mph, almost hurricane strength. When all was said and done, 21.2" of snow officially fell at O'Hare, but with all the blowing and drifting, its likely the true number is higher. Still, that snowfall is good for the 3rd highest of all time, dating back to the late 1870s when record keeping began. With the historic precedent and lasting impact felt by this storm, the ABC 7 Weather Team deems it worthy of the #1 spot on our list of the top 10 weather events of the decade.
