I remember the winter of '76-'77 very well ... I was 25 at the time and living in the D.C. area. It was very cold for a lot more than just one month. 

 

Unreal pictures from back then with people well out into the bay and cars on the ice at mouth of south river into the bay.  You could not tell where the land ended and the ice began 

it did moderate in Feb

Interesting that you have a sorta different subseasonal cycle than a lot of the other forecasts.  But still end up in the typical Nina dud for snowfall (which I tend to agree).

Subseasonal cycle? You mean the progression, ie mild January?

Largely based on how I think that the stratosphere will behave....PV is probably going to rebound quickly by the new year given that we are likely to have a reflection event mid January, the precursor pattern for which is a Pacific trough....implies Arctic low and Pacific trough for early January.  Then SSW in February for a colder finish.

I certainly hope we get some period of productivity in January. A lot of the Ninas during the last ~10 years have had good January periods. I’m not enthusiastic on snowfall if our best patterns are early December and March.

Doug Kammerer thinks January will be coldest month relative to normal. What is he seeing?

Snow flurries in Atlanta today  It's just flurries but given the SOB (south of Baltimore) storm track that has persisted for most of the decade, it's still annoying nonetheless.
