EASTERN US: 3 Snow Systems & A Major Arctic Air Mass

Written by on March 9, 2017 in United States of America, Winter 2016/17 with 0 Comments

A lot of attention has been on the big storm taking up half of North America’s atmosphere and rightly so, however an exceptionally cold air mass (by March standards especially) has been building over the Canadian Archipelago in the past week (remember the end of February strat warming event?), temperatures have reached all-time record levels in Mould Bay, NWT.

Thanks to the Hudson Bay storm, this record cold has drifted south and west.

While that low spins, heights build over Greenland and are set to reach Alaska which forces the Arctic high southward.

The presence of high pressure over northern British Columbia/Alberta and low pressure over Hudson Bay has been driving exceptionally mild air north in front while it’s beginning to drive bitterly cold Arctic air south down into central Canada and eventually the US.
