I was about 2 miles from my destination, when I saw in the distance.. a wall of rain that was pretty impressive.. quickly detoured about 2 blocks to the people mover, got to work after worst of rain passed by, but about 20 minutes later than I would have had I just hammered through it.

Deciding factor was lack of visibility, rain isnt' bad, but if cars can't see you, that makes it easier to hit you... Happy weekend!
