Man where are you getting your info from. There's nothing that suggests a big warm-up around the holiday. Plus, it's a month away. You know as much as anyone else that things are going to change in another week and a half from now. I love the way you say these things to just try to help your reverse psychology theory. As soon as we get a real threat, you're going to be on top of it like white on rice ( just like the rest of us ). 

Well Ray’s write up did feature said warm up sometime around that period, so…

Wonder when the GFS and foreign guidance is going to converge on Tday. GFS still like a full day slower with that trough. Foreign models all have the front offshore by Tday morning.

He mentioned you as one of the ones making that claim.

There’s some concern from some of the energy Mets around Christmas. It’s a month out so I don’t really care at this point.

Nor should anyone else, A month away many things can change, I guess i somewhat understand the thinking if you compare that period to the past few years.

GFS a few more cycles away from being a full on Turkey day snowstorm for NNE at least..

Nasty and wedgy on the gfs. Let’s either delay it or get it out sooner.

SWFE on 12/3? Decent NoP anyways.

There’s so me well known Mets that are thinking we only have until the 15th. Not making it up 

Obviously I'm not a met, but my stance is the pattern begins to break down by mid month into Xmas...probably not "warm". I may have def. rushed that though given the weak antecedent nature of the PV in conjunction with the anticipated behavior of the MJO. Just don't be surprised to see the second half trend a bit warmer.

But then there's this...

The Madden Julian Oscillation or (MJO) is really important when it comes to long range forecasting during the winter. Thunderstorm convection initiating over various regions along the equator while simultaneously other regions are drier corresponds with a total of 8 phases we monitor that influence the weather patterns over various regions across the globe, including North America. 

When you have a lot of convection over phase 6 which is the Western Pacific, it likes to enhance a very warm pattern over much the US. Currently we are in a phase 6 and it’ll make sense to you if you have been outside today.

When convection sets up a little further to the east over the Western Pacific, we call it a phase 7. That introduces more cold air back to the US, but is met with some resistance from a ridge of high pressure over the Southeast US that tries to keep this part of the country milder. As we head into Thanksgiving, we’ll see a brief shot of cold air for a few days, but going into early December it will be met with a return of that ridge which will again increase our temperatures for a time.

When convection begins to shift into the Western Hemisphere, we call that phase 8. Phase 8 corresponds to cold overwhelming the pattern for the central and eastern US. The projected evolution of the MJO in the coming weeks is to go from 6 currently to 7 during the last week of November and early December and into phase 8 by mid December. Until that time our temperatures may be highly variable. Once we get into phase 8 mid-December, steadier cold air will become more predominant and winter weather chances will hopefully increase just in time for Christmas!
