If we're getting a minor warming soon, the PV will probably restrengthen for December and we'll torch. But after that, we may get another warming in time for some blocking in Jan/Feb. That would be our window if it pans out.

I mean December was an expected loss anyway. Hoping for the late January into February/March boom

Hopefully that would set us up for the 6 week reload right around the holidays.

That's the best case scenario. The worst case? well... 

I'll be in Quebec during the holidays. Even if it torches in the east, it'll still be cold enough there for snow.

You never know about the holidays!

60 years ago in 1966, Augusta had a high of 31 and low of 18 with 6 inches of snow.

61 years ago in 1965, we had a high of 62 and low of 46.

There has always been high variability around xmas.  However, it's skewing more and more the wrong way.  

Prior to 2010 the median high in DC on December 25th was 42.

Since 2010 the median high is 51.  

From 1945 to 2009 DC had snow on the ground 13 times.  It has now been 16 years since there was snow recorded OTG on xmas.  

There is always variability, but within the variability is a trend.  December is the Winter month most affected by warming.  Both in Temps and Snowfall.  We are losing it as a winter month basically.  It is what it is.  

We have lost about 18% of our snowfall climo in the last 50 years and December accounts for most of that loss.

Seems we might have a + NAO October, I believe thats a good thing.

The 1960'S was  a "wild and woolly" decade !!! 

3 Christmas Day snowstorms.   1962 6 inches,  1966  6",  1969  12" 

It hasn't happened since.

Wow! 12" in 1969. We had 5" that ended as zr just south of BWI. But it was great nonetheless. I remember it well. (at my age, remembering 57 years ago is easy....it's 57 minutes ago that's the problem  )

I mainly track ENSO for its effects on tropical cyclone activity but I do have some surface-level knowledge (emphasis on "surface-level") on its correlation with NA winter synoptics. From what I gather 1997-98 seems to be a prime analog this year given the strength and flavor/orientation of the Niño which isn't promising (torch city with very little resulting snowfall as a result). I would also think the comparatively greater magnitude and eastward extent of this event may be cause for even more concern this time around? Because we're at record levels in both cases:

Hopefully I'm wrong and we do find a window or two where we are able to cash in within an established unfavorable pattern though.
