Cold air does nothing

 

That cold blob had everything, but it was stopped by warm Atlantic air.  I'm sure there were some good snow storms.  Now, we are getting hit by a very high plume, straight from the Arctic.  This has lots of cold moisture.

That plume should be warm, but it bounced off the North Pole.  Once again, I've never seen something like that, just like it has been all winter.  We'll see what it does.
