Cold weather fans rejoice! Much colder temperatures, possibly arctic air invades the western U.S. and spreads south/east next week. The map below shows the 850mb temperature anomalies for Thursday, December 8, 2016 per 12z Euro Ensemble model. Source: http://www.tropicaltidbits.com/
Note: Right now it looks like high temperatures will be in the teens and 20s in the Northland with lows in the single digits with subzero lows possible -- The core of the coldest temperatures look to setup to our west, over the Rockies and northern Plains (Subject to change) Timing of this looks to be from the middle of next week into next weekend (Dec 7-11 time frame, give or take)
Note: If we can build up a snow pack prior to the middle of next week, then it would likely end up colder in northeast Minnesota and northwest Wisconsin.
