The cooler air is being anticipated by changes in the upper atmosphere, dropping colder Canadian air down from the Dakotas. This upper level pattern shows that colder air drives in by Saturday Dec. 17, and lifts within the days after. That would lead to much cooler temperatures for the third week of December.

When it comes to the precipitation outlook, the CPC believes that we will be near normal for December 18 through the 24.
