This is my biggest storm since 2018

Only 1/2” so far, eyeballing.

lol recent Ninos have not been good here. Nina baby!

Wow! I just checked the radar loop and your area has been under the best banding all night. Love it.

I recently complied the data in more detail after getting some comments on exactly where the cutoff may be. This is what I posted in the NYC metro forum a few days ago and I will update when this month is complete. It seems to be that 4 to maybe 5 inches is where the cutoff level is. But the main takeaway is that the average to above average seasons went 6”+ in December. The snowfall data below is what I post each December for La Niña conditions using the newer RONI definition due to the warming of the global oceans. The December to seasonal snowfall relationship has worked 14 out of the last 15 times. My guess is the reason for the reliability as an early seasonal marker for below and normal to above average snowfall across the entire season is related to the La Niña seasonal progression. They tend to be more frontloaded in nature so their seasonal snowfall pattern is usually revealed early on in December. Plus in our warmer climate we have been noticing more repeating patterns perhaps related to non linear convective thresholds being met in tropical oceans driving the forcing. The relationship holds for NYC, EWR, and LGA. I will post the data for NYC below which is similar to the other two stations. For the sake of this discussion I have been using 4” of snow in December as the cutoff. But it’s possible that it could actually be a little higher around 5” inches based on the available data. So it’s fine if someone else wants to use a 4-5” snowfall range for December snowfall as the cutoff line for below and normal to above normal seasonal snowfall. I am not making the argument that the December snowfall is causing the outcome of the rest of the season to change. Just that it serves as a marker of what expect the rest of the season. Sometimes two data points can be related due to other underlying variables that may not yet be fully sampled by our current scientific understanding. I will update this post once we have the complete December snowfall data.

Another 1.5" has fallen since 445am now up to 7.5" of snow. Still heavy snow temp at 29.7

We need to move to a Nino to put you back into place

Another 1.5" has fallen since 445am now up to 7.5" of snow. Still heavy snow temp at 29.7

Christmas comes early this year.

32.7 so it's getting better finally going be mad icy tonight though

2.5". 32.2F

25 degrees and just a dusting overnight. The high yesterday was 28 degrees. Never even got above freezing, a-shame all that cold going to waste. That’s my only gripe. Everyone enjoy your snow

Just woke up to about 5” on the ground in Allentown. Looks like we have one more band on its way to potentially push us closer to 6”. Great storm, love seeing something like this in mid December.

4.3" and done snowing...didn't melt the tube yet...Valley Green, Etters, PA

Snowing hard now with nice sized dendrites. Seeing some yellow on radar. Hopefully this lasts for awhile.

27F Dp27 winds NW@6 not official but looks like 3-4”moderate snow still falling but looks like one more heavy to come through and that’s all she wrote out this way should be all said and done by 7ish. I’ll measure in a little bit. Congrats Mt. Holly spot on forecast out here in western Berks

At least everything is white. Pretty with the xmas lights!

Maybe an inch in Arlington . Curious what the total precip will be.

I don’t think I could get more than a 0.5” measurement off my deck right now. I’m calling it a night but will trust whatever comes in spotter report-wise for me. really kinda had 1.5” as my floor… whoops

1.3" at 5:40AM

35 and finally flipped to all snow, let’s see what we can get out of this.

Columbia 5:45am. Nice snow ongoing! Temp 32° Eyeballing 1”-2” OTG

~2", eyeballing.

A dusting, 26° very light snow

But hey...it has snowed a couple times this December and it has been cold. Maybe we are slowly turning the corner to bringing December back as a winter month. March snow is rude
