Midwest headed for the deep freeze?

After a brief flirtation with wintry precipitation on Monday, December the 5^th, we will finish the rest of the week dry but colder than normal. This will be due to the weather patterns that will feature a cross polar flow which will usher in very cold polar air in a series of waves with nothing to stop them. Combined with this feature will be a gulf that is shut off as far as moisture in concerned. This pattern should persist through the Saturday, December the 10^th when a new shift could bring warming temperatures once again.

This pattern of chill down followed  by warmups  could well set the stage for some interesting winter weather as we approach the middle of December!
