getting colder jan 2

When you compare this picture to dec 20, many dramatic differences. The magenta area in north america has expanded dramatically, and there is a new cell in the USA now. The blue area is completely solid between Greenland and Canada now. Northern Europe is filled in with the dark blue.

The green area has expanded a bit above Iceland, and Tibet blue cell has shrunk.

But there now is a a very dark magenta (-45 F) in Siberia for the first time.
