We had some wicked weather to end the month of June last night in the Chicagoland area. First line of storms rolled in around 6:30/7:00pm. I was meeting some co-workers for dinner and as I was walking to the restaurant I noticed it went from being very hot and muggy and still to very cool, dry, and breezy, and then a minute or two after I got in the restaurant, the rain started coming down in sheets, coupled with 40-50 mph wind gusts. Luckily this first round of storms turned out to not be as bad as forecast.
Then round two came just as we were leaving the restaurant around 9:45. This came as a complete surprise and was very violent. I wound up getting to my car right as the rain started to fall, and then then as I got out on the road, the rain and wind and lightning were incredible. As I was driving home, I felt like I was driving through a river the entire time because there was so much water on the road. Tree branches down everywhere. Traffic signals out. Police blocking off various roads. Then a weather alert came through on my phone. I didn't check my phone at the time, just assuming it to be a flash flood warning. But when I did check my phone when I got home, it turned out it was actually a tornado warning. :-o
There was widespread wind damage throughout the Chicagoland area, including some straight-line winds of 70-100 mph (essentially hurricane force) and five EF-1 tornadoes in places just to the south of me in La Salle, Kendall, and Will Counties. Places like Earlville, Mendota, Morris, Plainfield, Romeoville, and Grant Park (a town north of Kankakee, not the lakefront park in Chicago) saw extensive damage, with roofs torn off, some buildings destroyed, and many trees and power poles uprooted or snapped. The National Weather Service has a nice write-up here:
