Arctic mechanism changing by the minute

 This really puts a damper on any attempt to forecast for 7 days.  You just don't know what this Arctic thing will spit out.

I'm just going to back to it every couple of hours.  You can see a perfect Arctic recharge vortex, but it is suddenly taking in a huge amount of warmish air from Siberia.  Everything is back-flowing into it.

The Canadian outflow has suddenly increased by a factor of 10.  I'll look back at it by lunch.

Basically, the mechanism takes regional warm air and cools it down to a dense sludge, which fills up the basin, and then spills out in some direction.  Still looks like its going to be Canada for a while now.  The Europe gate is just too clogged up with the Gulf Stream heat.

ps OMG, dog walk was freezing!  I'll have to go up another level.

ps the flow has been cut off.  Something to be said about not checking too often. Back to once a day.
