I wish this photo did the sky more justice. It was so black to the left that it looked like night, and it was 6:30pm on Sunday night coming north on highway 55. Soon, I was driving in rain so hard that I could not even see the shoulders. I wanted to pull off, but I could not see where to pull off. I could only faintly see the tail lights in front of me, as we slowed to 35mph. Scary.
