December 2025 OBS and Discussion

[wdrag]

I've appended the week 3-4 CPC Outlook issued 11/21 and the monthly outlook issued 11/20. Click for clarity.

There has been discussion of the stratwarm impact on North America In December.  I hope I'm very wrong thinking "is that all there is around the NYS subforum?"

For now unless the 5H cold core recenters - penetrates significantly further south into Hud Bay (below 60N) or we develop a 'general' +PNA, -NAO  in December,  its impact here in the northeast may be minimal. I just don't know.  Others hereon are more informed. 

Entire month open to discussion...bring on the snow and lets get off to a good start in CP etc.  

[NEG NAO]

At least the storm track will not be too far south according to their Precip Outlook and  the Polar Vortex is not going to plunge too far south  when it is stretched by the Strat Warming Event according to their Monthly Temp Outlook. Heard that the Vortex will be stretching rather than a full displacement............
