When coldest of winter starts from the South, the new climate normal

 ~An Arctic perspective use to portray cold winds from the NORTH

~Now cold atmospheres start from the South

Pay attention to the High Arctic weighted temperature of the entire troposphere.  At beginning of January till mid month the coldest air was further South,  then after the Cold Temperature North Poles grew in size,  the coldest temperatures finally settled in the High Arctic.  This climate shift is recent.  Basically implies a warmer Arctic,  on land especially over thinner sea ice.  Still implying the bulge of winter moved Northwards in several locations.  Over the oceans and virtually on every part of the continents,  whereas winter of old still exists but for much shorter time periods.  On the North American side,  the CTNP settling over the Eastern High Arctic give more often than not the warm winter periods of late.    However the less expansive Cold Temperature Vortice centers on each continents make for dramatic weather changes,  which make the news because these weather events are usually out of time and place.
