Pacific air pours over the mountains

 

A plume that doesn't look like anything is pouring air over the mountains.

This is like last year, but with a totally different mechanism.  

It's very cold in the Arctic, but all the air is staying there.  It hasn't settled into a new pattern yet.  I am flummoxed.  

ps.  the dailies are all dropping again.  

pps.  it's incredible to watch the plumes smashing into the mountains, stopping all attempts for an Arctic spill to form.

more - and that's a combined double plume.
