The Cold Is Coming

By far, the coldest air of the season is on the way and it may stick around for awhile. This week will be mild, but the cold dives out of Canada Friday. Play the video below and watch it dive out of north and engulf much of the country.

Birdseye view of the northern hemisphere below. Strong ridging in Canada will set this up. The strongly negative Eastern Pacific Oscillation supports this. In it's positive phase, lower pressure off the west coast of Canada/U.S pushes Pacific air into the country and that's typically mild. In the negative phase, it opens up the arctic gates as ridging goes up in Alaska and the arctic.

GFS EPO is strongly negative= cold

Euro EPO is strongly negative = cold

Won't be perfect, but you can see where this is all going. Euro ensembles mild this week, then turning much colder

GFS ensemble has the same message.

What about snow? I would not be surprised to have some sleet and/or snow in the Ozarks at some point before the end of the month. That would not be all that unusual though. Get ready! Cold is coming.
