Chicago Summer Storms

I flew into Chicago Monday night. Within about 30 minutes after the plane landed, a huge storm lit up sky. The sirens wailed amid tornado warnings and lightning strikes hit all around the city. I've never seen anything quite like it. The storm lasted late into the night and the thunder roared among the huge skyscrapers like cannon fire. The rain came down in waves and the roads flowed like rivers. It's been nice since but wow, that was quite a storm.
