The polar vortex

I saw on the news that there is a polar vortex that is taking over the eastern half of the U.S. today through Tuesday.  The local news reporters have said that there will be record breaking low temperatures on Monday and Tuesday.  I think here the lows may reach into twenty something below zero.  We are expected to get a total of 6-12 inches of snow between last night and today.  I read on MSN that the state of Minnesota has cancelled classes at every school for Monday due to the expected low temperatures.  I took a couple of pictures at 9:00 this morning, but the snow is even higher now.  We are going to stay in and hope that the power doesn't go out and that the heat continues to work.  With the wind expected, it is supposed to be blizzard like conditions.
