Timing Of The Cold
Through Saturday: The second blast of arctic air will plunge out of western Canada southward into the Rockies and Plains, reaching as far south as Texas by late Saturday.
Sunday: The cold air will spread into the rest of the Midwest and parts of the South from Texas to the southern Appalachians. The cold will intensify in the Northern Plains and upper Midwest.
Monday: The colder air should finally reach most of the East, with the exception of Florida, and remain quite strong over the upper Midwest and Plains.
Cold Highlights
The second cold blast will likely be the coldest of the season, so far, in the Northern Plains and upper Midwest.
The bulk of the worst cold has already arrived across the Northern Tier and it will continue to slide south and east this weekend.

Lows Monday morning could drop below zero degrees from eastern Montana to the Dakotas, parts of Iowa, Minnesota and Wisconsin.
And wind chills in the Northern Plains may plunge into the teens, perhaps 20s below zero this weekend into Monday.
How Long Could It Last?
If you're already sick of the cold, is there any relief after this second arctic blast?
For some, yes.
While NOAA's 8-14 day outlook below indicates more persistent colder-than-average conditions in the Midwest and Northeast, there is some relief later in the first week of December in parts of the South and West.
