Good morning, commuters!

Here we go again. The temperatures are low enough that black ice is a definite possibility.

So far, no problems on the highways and freeways.

The first inbound Northstar train is running on time.

I'll be keeping an eye on the roads and rails this morning, reporting any delays or issues — and I will need your help.

If you see or hear about any congestion, delays or problems, e-mail drive@startribune or tweet @stribdrive.
