Sure does. Can’t remember many years riding the train when I’ve spotted it this widespread this early. -

It will turn briefly milder tomorrow. Some rain showers are likely tomorrow night. Some wet snow showers could occur well north and west of New York City. It will then turn somewhat cooler for the remainder of the week, but the cold won't match today's chill. Light precipitation is possible during the weekend, especially on Sunday. The ongoing stretch of below normal temperatures will likely continue into or through the second week of December. December 1-10 will be a solidly colder than normal period. The potential exists for the coldest first 10 days of December since at least 2007 (33.4°, 5th coldest December 1-10 since 2000). The five coldest December 1-10 periods since 2000 were: 1. 30.6°, 2002 2. 32.2°, 2003 3. 32.4°, 2000 4. 33.1°, 2005 5. 33.4°, 2007 All 5 of these cases had measurable snowfall in Central Park. The WPO is forecast to become strongly negative beyond December 10th. That would likely contribute to the December 10-20 period also being colder to perhaps much colder than normal overall. The probability that December 2025 will have a maximum monthly temperature below 60° is increasing. The last time that happened was in 2019 when the monthly high was 58°. If 2025 has a monthly high below 60°, that would be only the fifth such occurrence since 2000 (2003, 2004, 2005, and 2019 are the cases since 2000). The ENSO Region 1+2 anomaly was -0.2°C and the Region 3.4 anomaly was -0.5°C for the week centered around December 3. For the past six weeks, the ENSO Region 1+2 anomaly has averaged -0.27°C and the ENSO Region 3.4 anomaly has averaged -0.65°C. La Niña conditions will likely continue through at least mid-winter. The SOI was +17.96 today. The preliminary Arctic Oscillation (AO) was -0.921 today. Based on sensitivity analysis applied to the latest guidance, there is an implied near 91% probability that New York City will have a cooler than normal December (1991-2020 normal). December will likely finish with a mean temperature near 34.1° (5.0° below normal). Supplemental Information: The projected mean would be 3.4° below the 1981-2010 normal monthly value.

This only works if December torches, like in 2015, 2021, or 2023. A cold December, like this one, makes it more likely, based on the law of averages, a torch will happen in January. The period of winter might already be happening. -

Its elevation dependent . Only those that live high enough in the mountains of wv might see blizzard conditions. -
I'd take those ECM runs every time. Weekend, daytime snow. 8-12hr duration. Temps freezing or below. We pray.

i don't think I want that!

I deleted my post. I realize you probably were talking about him. I don't find him to be all that bad. Not compared to a lot of these other bozos. -

Glass half full: Most are above average snowfall by 12/15 with 9/10 days left for models to mute the Christmas torch and associated cutter, if still applicable -

Not you...the northeast weather alerts guy you referenced. -
The Friday system is moisture starved and the Sunday one is basically a cold front with most of the energy further north: https://www.tropicaltidbits.com/analysis/models/?model=gfs®ion=us&pkg=z500_vort&runtime=2025120918&fh=114 I guess we can find a way into a light snow event from both systems, but the real snow producers are when we get some southern stream influence which has been really hard to come by in these neck of the woods.

Back up to 13.5/3.6°F so that was short lived.
