Another Shot of Extraordinarily Cold Air?

Maybe.
National Weather Service Ft. Worth
Above shows two paths for a low pressure system that seems to be about 7 to 10 days out. The white area in Siberia is air colder than -30°F. Some of the extended-range computer models have only part of the air mass breaking off and giving the U.S. only a glancing blow.

But, others are showing nearly the entire air mass moving over the pole and right into the central U.S. That would be roughly Friday the 21st and the weekend of the 22nd-23rd if those models are right.

Of course, with pre-Christmas travel picking up that weekend, you can be assured that I'll be posting about it as it becomes more certain.

  1. This will be interesting to monitor to see if it verifies. #2 would be the far more troublesome storm if it dives as indicated in yellow.

  2. Local WX discussions indicate models are starting to latch onto a deep freeze coming end of next week, at least to the intermountain west. NWS Boulder forecaster labelled it as "Brrrr Humbug" yesterday. We shall see...
