We've chosen the top 10 weather events that have impacted so many of you over the past 10 years.

And it was not easy going through all of the data, but the ABC seven Chicago weather team, we have done our best and we have chosen the top 10 weather events of the past decade.

Here they are starting off our list at number 10.

The largest hailstone to ever fall in the state of Illinois that fell on June 10th 2015 in Minooka, Illinois, the hailstone four and three quarter inches in diameter.

Although that sounds huge.

The largest hailstone to ever fall in the US was almost double that size at eight inches in diameter and that fell in South Dakota.

Number nine is the unprecedented rainfall that led to historic flooding on area rivers, April 17th and 18th.

2013.

Many locations got well over seven inches of rain.

The worst flooding was right along the Fox and Dis Plains rivers, both which reached record crests, many homes were flooded and it took weeks for the rivers to recede.

Number eight is one of the coldest February ever.

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.

That's a full 13.1 degrees below the monthly average.

And it wasn't just the cold that lands this frigid February in the top 10.

It also snowed a lot that month with 26 inches of snow reported in that frosty Frigid frozen February of 2015.

Number seven on our top 10 list is another record rainfall event.

This one in the city of Chicago, over six inches of rain fell on July 23rd, 2011.

This is 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 so remarkable was that most of the six inches of rain fell in just a three hour window.

This led to extreme flash flooding.

Number six on our list, a very rare November tornado outbreak.

This one especially notable here how warm it was before 12 days before Thanksgiving on November 17th, 2013/25 tornadoes were reported across the state of Illinois and 30 were reported in the state of Indiana.

The largest of those one that I'll never forget personally, ef four tornado with winds up to 190 MPH that hit Washington, Illinois.

I was actually on scene for the damage the three days following this and it truly left a trail of destruction, nearly wiping out the whole town.

The EF four tornado that went through Washington alone did $935 million.

Number five, we have another tornado outbreak for you.

This one perhaps even rarer than number six.

It's the first significant February tornado outbreak in the history of northern Illinois.

On February 28th, 2017, 10 tornadoes touched down in Illinois including an EF three with winds around 155 MPH that struck Ottawa and play.

The video of the tornado is breathtaking in the Ottawa cell hail.

The size of baseballs fell.

These tornadoes turned out to be deadly, leaving 14 injured and two killed and leaving a long path of destruction.

Number four takes us from winter tornadoes to record spring warmth.

During March of 2012, we set record highs for nine consecutive days and including an unbelievable 87 degrees on March 21st.

This was our all time warmest March by nearly five degrees.

Flowers were blooming more than a month early as temperatures were above normal.

27 of the 31 days of the month into the top three, we go our ABC seven weather team.

All agree.

These are events that will be talked about well beyond our decade.

With number three being the polar vortex, the polar vortex of January 2019 gripped the Chicago area with life threatening cold.

Just how cold the all time coldest temperature ever recorded for the state of Illinois occurred during the morning of January 31st when the temperature dropped to 38 degrees below zero.

In Mount Carroll Illinois here in Chicago, the temperature dropped to negative 23 degrees and an aurora negative 32 the wind chills during this period made it feel like it was 50 to 55 degrees below zero.

The temperature stayed below zero for over two days until the thought started.

And Chicago recorded its second coldest high temperature ever of only negative 10 degrees on January 30th.

Number two is the tornadoes we saw in the year 2015, both numerous and violent because of that.

We combined two large tornado outbreaks that happened into our number two spot.

The severe weather season got off to a quick start with the first outbreak occurring in April on April 9th.

2015, 11 tornadoes touched down in Illinois.

Six of these tornadoes were spawned from the same super cell with one of those tornadoes being an absolute monster and ef four with winds up to 200 MPH.

This tornado was on the ground for 30 miles from Franklin Grove to Fairdale.

This tornado took two lives.

The second outbreak occurred on June 22nd 2015 when a dozen tornadoes touched down in northern Illinois with 10 forming from just one super cell, one of the 10 was rated in EF three and had winds up to 160 MPH.

Those winds hit both Coal City and Braidwood.

Thankfully, no one was killed in that tornado but 11 people were injured.

We knew what number one would be before we gathered the other nine.

We're sure by now you can guess too.

What list isn't complete without the historic Groundhog Day blizzard.

Many of us lived here around the station for three days as we couldn't get home.

So yes, we plan to pack our bags.

What was really interesting about this storm is we had some really good lead time with data.

The models were all coming together days in advance to warn us.

This would be a significant storm State street.

That Great Street was snow covered and deserted so that blizzard takes number one 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 boarding CT A buses to stay warm until they could be rescued.

Winds along the lakefront gusted to 70 MPH.

Almost hurricane strength when all was said and done.

21.2 inches of snow officially fell at o'hare.

But with all the blowing and drifting, it's likely the true number could be even higher.

Still that snowfall is good for third all time dating back to the late 18 seventies when record keeping began with the historic precedent and lasting impact felt by the storm.

The ABC seven weather team deems it worth the of the number one spot on our list of the top 10 weather events of the decade that wraps up our list.
