FC9CC4BE-2783-4041-B125-61D9607432F1.gifHow can a cold lover in the SE not like this GEFS trend of today in the PNA? This is the best it has looked in a long time with it now turning positive in the means late. Also, I’m really interested in how strong a -PNA December will end up at. This sure looks like a top 10 Dec -PNA and quite possibly is top 5 (since 1950).
 
Wouldn't call it a pattern change. This would definitely be a needle threader. Well timed wave in between two massive ridges and a very marginal cold air source. That could happen anytime in winter in any regime.
This is definitely a pattern change, not sure what you’re talking about

It was top 2 December -PNA as of Dec 20. Might be strongest ever
