Not sure why people are so dull with our pattern change today. It looks as good as it ever has, in my opinion. NAO continues to be shown going neutral/negative, the AO continues to be shown going negative, and the PNA continues to trend away from going negative, and looks more neutral now. Either way, the PNA isn't concerning me because our AK vortex is moving out of AK and into Canada (Not sure exactly where yet) and our EPO and WPO will go negative, only increasing the cold air in our country. The MJO is now in the COD, which will help keep it away from interfering with our pattern for the most part. From there, it looks like it spins around in octant 6, 7, and the COD, which are fairly OK places to be. Big system comes around on the 12th-15th of January, just as all these variables go favorable... That spells a pattern changing system to me. Yes, it will be rain, but that was expected. The question is, what exactly happens after that system... Cold and snow?
