Minor snow possible sunday 12/14/25

[brooklynwx99]

just a classic post-2016 NYC metro subforum exchange about the RGEM lmao

[eduggs]

For the center of this forum's region, as depicted, the 12z NAM would bring warnings snows, the 12z RGEM would bring an advisory, and everything else that's out (ICON, RRFS) would bring sub-advisory light snow/flurries.

So basically the models that actually matter are light snow at best

RGEM is pretty decent as a model-wouldn't discount that.  The NAM is mostly garbage especially at this range.

If you have NE winds off waters in the upper 40s still, that’s a problem for SE NJ. Most coastal storms this time of year have that problem and warm up SE of 95. 

[WeatherGeek2025]

anybody saw the CMC?

[snowman19]

I will say this….for a storm less than 2.5 days away, there is ridiculous disagreement with the models. You have the NAM/UKMET in one corner showing a full blown snowstorm. The RGEM I guess in the “middle”, the CMC hasn’t run yet for some reason, but assuming it will look like the RGEM. And you have the GFS/RRFS/GFS-AI/ICON with a minor event. Let’s see what the EURO/EURO-AI does…..

Good trends at 12z so far. UK kind of splits the difference between the RGEM and NAM.

[eduggs]

Is there a chart on what models seem to matter?

There’s always a seemingly week-to-week change in the rankings depending upon people’s moods and emotional states.

all levels will be below freezing during the storm!

[Jersey_Snowhole]

Euro hr 51, 1031 H in the center of our precipitation lol make it make sense 

[bluewave]

The 12z Euro 2” for NYC would be a nice little event.

That doesn’t cause high ratios. You want temps between -12 and -18C in the clouds where snowflakes are made which promotes good snow growth, and plenty of moisture/lift in that layer. If temps are higher or lower it will hurt ratios. I remember a few times temps were in the low 20s or even teens but we had tiny sand or needle flakes that were 10-1 ratio. 

[winterwx21]

Euro looks like a solid 2 to 3 inches for a lot of the area. I'm starting to get excited -- this is looking like a decent advisory-level event. We really need to cash in with this one before we flip to a milder pattern late next week. It's nice that the snow will stay on the ground with very little melting for a few days.

Totally wrong

[WestBabylonWeather]

We need 3” for statistics to be in our favor 

[WeatherGeek2025]

Has anyone heard Walt's opinion on this potential snow threat? i'm hoping for that high end 3-6
