At the same time, I predict a the West Coast and the Rockies to become under a warming trend. The Plains and Midwest back through the Ohio Valley, along with the southern sections of the East Coast will likely be influenced by this sudden colder air mass in place over the South US, so slightly cooler temperatures can prevail.
Nowhere near as cold as what was experienced this week.
More pressing is the potential for a major winter storm on the East Coast back through areas of the Southeast.
While this should be a rain event, Tennessee, Kentucky, and areas around those locations should see more of a snow event.
While most accumulations are preliminary, it should be safe to say that at least 1-2” is in the realm of possibilities.
