That's right, folks! An Arctic outbreak could occur in the East Great Lakes area on December 9th.
In the above picture, we see the Jet Stream diving south from the Canadian regions. It will mainly affect the Nation's Heartland, but the Great Lakes could get in on the action.
The probability of this in the Great Lakes is 14% to 29% according to my formula.
For the Heartland, The chance is about 29% as well.
But other models show this as higher. Using an additional formula, the new chance is now 64%.
Will it play out? We'll have to wait and see.
