I’m starting to think we won’t be getting a February thaw this year. This pattern that we’re in doesn’t seem to be breaking down looking out the next 2 weeks, which takes us to February 22.
The coldest anomalies remain anchored over western Canada, western U.S. and northern Plains (Purple and darker blue colors on map) Will see some of that real cold air break off and push farther south/east into the upper Midwest at times for the next 2 weeks, but the most persistent arctic air should remain a little farther west from Minnesota based on long range model guidance — This pattern could also be a stormy one at times as a series of low pressure systems track east-northeast out of the western U.S. for roughly the next 2 weeks.
