Low 20s with a light snow the entire ride. Nice and pretty.
I had my 3rd low speed ice related fall. You would think I would learn after #2.... no... not I.
I was riding through Washington Park one handed eating a sandwich. Low and behold the light dusting of snow had hidden a sheet of ice. Tipped over at maybe 8mph.

Nothing is injured except my ego.
Besides that fall everything went well until I hit the southern suburbs. What a mess. Here I am hauling arse down a hill and notice up ahead that my lane (rightmost of 3) is disappearing under ice and snow. I then slow down to a crawl and notice that all the other lanes are disappearing. Consequently I walked my bike off the street onto a path and walked 2 blocks until it cleared up. Another path I use going up a steep hill was a solid sheet of ice as well. Combo walked and rode the bike slowly up the hill. Only 15 minutes late.
