In layman's terms, as the planet warms and Arctic sea ice melts, the northern polar region equalizes a bit with temperatures farther south, causing the jet stream that forms a circular band around the northern latitudes to slow down.

This jet stream usually holds the far colder Arctic air in place with winds in excess of 100 mph, but pockets of cold can escape at times when the stream slows down, according to Time. That's exactly what's happened this time around, except the amount of cold that's leaked past the seal is much larger than usual and has pushed farther south (take a look at this interactive graphic from the Guardian for a better visual).
