The challenge this winter is finding different ways to describe the cold and snow without consulting a dictionary or thesaurus, or without losing your mind! All kidding aside, there is some warming potential the 1st week of March. I don’t see anything super warm or anything (especially with this giant sheet of snow over the Midwest), but we will most likely finally get above freezing for a few to several days.

Snow cover on visible satellite:

The reason we are expecting a warming trend is that the jetstream winds will change. The upper level ridge that’s been keeping Vancouver and the Pacific coast of North America warm will break down a bit, and push into Central Canada.

Monday upper level flow from GFS model:

So far this month its’ barely moved east a bit, leaving us open to day after day episodes of cold. With the way next week is looking, we may go above freezing as soon as Wednesday, if not then by the end of the week. The million dollar question remains: when will the snow cover disappear? I’d bet April rather than March, but a lot can change in the next few weeks (change is good at this point).
