The cold may not be getting as much play as it could be. Taken literally, the 18z GFS has the coldest 850 temp on record at Minneapolis. The 12z Euro is top-10 coldest. Excellent chance it doesn't verify, but that is still a nasty cold airmass rotating through the northern tier of the US. When you have the cold, there are always chances for something. Maybe we can get lucky on the retreat.
