Reasons Why This Winter Is So Cold

March 1, 2014, 10:00 PM by Grant Smith

Reasons Why This Winter Is So Cold

Average temperatures for February have been around ten degrees below normal. This is due to a particularly strong yearly cycle known as the North Atlantic Oscillation. 

The North Atlantic Oscillation is simply the location of pressure systems in the (you guessed it), North Atlantic. This winter in particular, the Low pressure has centered itself over the Hudson Bay. As the center of the Low rotates, we see average temperatures rise and fall. When the center comes back around, it shoves that cold arctic air right back down to KELOLAND and the surrounding area.

So what can we expect in the forecast for this North Atlantic Oscillation? Well, this cycle affects us the most from December through March. The forecast for the next two weeks shows the cycle weakening, so you can expect a slow warming trend after this weekend.
