We will have cold air as a source region in Canada and teleconnections are still largely forecasted to be negative from next week through January. I’d like the PNA to be more neutral but I don’t think we’re in a horrible spot. Unless I’m wrong, but I think a negative EPO mixed with a negative NAO should be a good thing for us.
February 2021 had a -PNA & the extreme cold STILL came to Texas with the -NAO, -AO, & -EPO
Correct. Why did it still work out? Blocking on both sides of the arctic. Alaska and Greenland and over the top. Pushed the PV to the US/Canada border. As the upper level lows ran down towards Texas, (they had no other path to take) they pulled down air from the PV towards the gulf coast. Wasn't a massive HP which brought down the cold.
It was not JUST the massive HP, there were 1060 MB HP's in the Arctic that helped to push it down. (And it lead to Below-Zero Temperatures)
