Wow, is that Cold!!

This is the 10-day computer forecast from the European consortium and the airmass over central Canada is the coldest I have ever seen on a model. The forecast is valid at Friday, January 14th. If this forecast is correct, it will bring extreme cold (think December 1983) into the U.S.

As posted below, I believe much of the U.S. east of the Rockies will turn sharply colder next week when compared to this week.  Confidence in that forecast is high.

Whether the second frigid air mass depicted above actually develops, or whether it is an exaggeration by the computer models, is unknowable at this point. I'm posting this so you can keep it in the back of your mind for planning purposes.
