Pattern December to Remember

Also watch this next Tuesday- Wednesday system to start creeping back into the picture .. some models and ensemble members latching onto it again and bringing beneficial rain to the area.. this type of thing usually happens on models with storms modeled off the SE coast during the winter months

Euro for example is back as well! Beneficial rains continue! Anything will help also check out the @Myfrotho704_ special!4060CEE1-DCF8-4DDB-B4C1-C09D8B84165F.jpeg23917430-2C69-4D85-9566-0AB21A8A7706.jpeg
 
To sum up the teleconnections on the 12Z runs, All have a strongly negative NAO/AO and a less negative EPO. The WPO is negative to neutral and the PNA stays strongly negative. The surprising thing to me is how close to the same forecast are for the CMC and the ECMWF, haven't seen this much before. Here are the CMC and Euro on the NAO

Here is the AO for CMC and ECMWF

A striking correlation.

Day 10 Euro. Don’t hate it, it has another massive winter storm for Pacific NW. we need to se that move on through. I do like the blocking going on up north. Hopefully we will see enough movement around the Aleutians to start moving that super cold air mass south, then I would assume the blocking would keep it over our neck of the woods for awhile.
 
Several years back, we had almost every indice against us except the PNA which stayed positive and we had a decent winter. This was all in spite of massive, repetitive gloom and doom. The +PNA kept things cold and interesting. Last year we had alot of great indices except for the PNA and it stunk - similar to this year so far. So with all the talk about the ensembles looking great in the future and all the indices except the PNA being great, we still sit here with mild/warm and no sure sign of a pattern change yet. So again, it seems to me the showstopper in all of this is the PNA.
