December 2025 OBS and Discussion

[Volcanic Winter]

Appreciating the deep January vibes today. 15F at 8am and a pack in no rush to obliterate itself. At least the cold start to Dec had a worthy finale.

It would have been insane to end this run of cold with almost no snow....

2.9 inches my a$$ lolol

Here is someone measuring the snow early in the morning at Central Park, the video was published between 7:30AM and 8AM, she already measured 3 inches on the bench and it snowed moderately and with higher ratios for several more hours afterward.

 

I embedded the video with the appropriate time stamp. 

So spare me the 2.9 inches bullshit guys, it's just flat out wrong.

It is total BS.  All those dumb stats are meaningless when pretty much every single other location, N, S, E and W got above 3"  Let the people circle jerk to their stats, that are obviously wrong, and the rest of us can live in reality.

It wouldn’t be the first low snowfall measurement there. I have pointed this out in the past with multiple other posters here. The actual measurement was probably closer to the 4.0” at Newark. Thanks for posting the video. It may have been Sam Champion last year showing closer to 1” too low in one of the events where he used his own measurement.

It’s very concerning with all the money now trading on predict markets where CPK measurements are the benchmark

The snowfall measurement may not be that bad considering that both LGA and NYC warmed up quite a bit at the start of the precipitation.

So they had marginal temperatures for accumulation earlier in the event.

When the cold arrived the best banding and higher rates missed to the east of NYC to LGA. Southern and Eastern Queens into Nassau and Suffolk got into the better banding. 

Probably a case of local subsidence just NW of  the best banding and marginal temperatures for accumulation. 

EWR and JFK are much more aligned with local observations. There is only one observation near central park for 3.1 and that's from a local. A local weather station measured 3 in the park at 8AM yesterday while it was snowing moderately and did so for three more hours. If this was a one time thing you let it go and say who cares, it was probably 3.5 - 4 so they made a mistake, but it happens all the time.

It's not like Central Park has a history of accurate snowfall measurements. As you probably know the Central Park Zookeeper kept the snow measurements from 1992 until 2014. That period was terrible for measurements. Most famous were the under measurement during the January 1996 and Boxing Day blizzards of 2010. Both were anywhere from 4-6 inches short looking at all reputable local measurements.

Things improved with the Conservancy from about 2015-2018 but started to go downhill again around 2019 or 2020. If it was once in a while you let it go. When it's fairly constant you have to wonder what is going on.

Just from yesterday look at the LE from the local stations around CP and you have to figure somebody's off. Temperatures were marginal at all of the stations, and the precip amounts are identical so subsidence did not come into play, so it's questionable whether either would be the reason.

NYC .51 inches 2.9 snow

JFK .53 inches 4.6 snow

EWR .52 inches 4.1 Snow

LGA .53 inches 2.6 snow

Snow shower/flurries quickly pushing into PA
