If we have to replicate that period, could we include a 1978 and 1996 in the mix?

I think we will get something similar. However we used up 1 above average snowfall winter on 2020/2021 now we only have 4 left lol.

so the storm tomorrow is now rain up to Kingston. The storm Friday disappeared. Now we’re in mid December.

 

Great.

it’s December 1 today but week 1 is done.

So really it’s December 8 for our purposes.

Great. 

A fast pacific jet will lead to a cutter/hugger and then suppressed storm track. Each year that features record marine heatwaves in north pacific just compounds this. At least we get some real cold on the backside of this storm, but like all the other winters over past 7 years, it's hard to get that to connect with the timing of the storm. So we do warm/wet, and cold/dry.

Let's hope we can get 4" here in December in NYC, or the chances of an average or above average snowfall this winter significantly decrease.

This is incorrect.

4 winters (40%) of the 1980s had below 20 inches of snowfall, the lowest 8.1 inches in 88/89.

Big difference between a 17” winter and 4” winter if you ask me. Central park 2.3 and 7.9 2022-2024, followed by low teens the following winter.  That is definitely unprecedented.

We still have 30 days to go for the final verdict on December, so a lot of time. But I will say this, just speaking for the NYC metro area and not any other place, in a La Niña winter, if you have a below normal snow December, in particular if you had no measureable snow in November, followed by a below normal December, it’s a very, very bad omen…..almost none of them throughout weather record keeping history have gone on to be above normal winters for snow and the overwhelming majority of them go on to be below normal winters for snow…..

From 1997 through 2002 central park had 2 winters of 5.5 and 3.5 along with 10, 12.7, 16.3

Also, 1989 was 8.1.

Euro is frigid for next week. We're getting the early season cold that we often get with a La Nina. Let's hope we can at least pull off a little December accumulating snow like we did last year. 

[NorthShoreWx]

I asked AI to predict the December weather based on this thread.  Not sure how/if it weights posts, but it said everything is going to suck forever and then we'll die.

In my own experience, there is close to zero correlation between these threads and actual mid to long term outcomes one way or the other (except for potentially the dying part).  But at least it's entertaining.

The next two weeks should cool the local sea surface temperatures (high confidence).

Great. 

Friday is a ways away in modeling time - with renewed cold worth watching.

Has been holding on with the cold signal.  Little doubt in my mind that the front half of December is going to be COLD.

Yeah our worst stretch probably until the current drought we're in. Thankfully 2000-01 saved it from being 6 bad ones in a row

On the positive side Dec 2002 began our amazing stretch

I feel like 2020/2021 is our recent version of 2000/2001.

I hope not, but it seems like tradition now that we grill outside in shorts around Christmas lately. Usually get so excited with all the ski areas opening up only to be hit with mild temps and slush during the holiday week, which then turns to ice in January. The good news is at some point the streak has to break.

30 here. Too bad it'll all be over here sooner than you can say "it's over" once winds turn SE. The retreating high and onshore flow are ruining it.

as soon as the clouds start rolling in later the temps will stop falling and might even rise a couple of degrees towards morning.

[lee59]

I am down to 29 but will probably be  above freezing by midnight if clouds move in.

[lee59]

Some temperatures in the Catskills already in the teens. Great radiational cooling night before clouds move in.

[lee59]

Seeing some real winter weather move into many northern areas so early in the season. Folks in the Chicago area will probably be ice skating this time next week.
