Arctic air dives south

Look at the wind field around this cold air diving south out of Canada.  It is part of the same storm system that is spreading widespread blizzard conditions across the center of the nation.

Temps range from the low teens along the Kansas and Nebraska border to to low 70s just off the coast of Louisiana.

The cold front has now pushed all the way to the Gulf Coast.  Light snow has been reported across southern Missouri and northern Arkansas.
