December 2025 OBS and Discussion

[MANDA]

Latest (12Z/30) EURO OP is locked, loaded and ready to discharge a bitter cold Arctic outbreak into the Mid-West / Lakes and Northeast starting next weekend.  Still time to work out the details on who gets how cold but reasonable confidence it is coming.

Probably our best bet for first accumulations of the season 

Colder airmass to start so yes I agree though similar setup to Tuesday with high escaping. Will depend on storm track 

Unfortunately think majority of snows occurs NW of our region. SNE and north will do really well. Borderline for NYC

For the coast that is..inland does well, which is climo for early December

It’s climo for recent gradient patterns no matter what winter month it is. We warm up enough for mostly rain near the coast with amped systems. This was the case last February. But since February is colder we were able to get a little more snow on the front end before the changeover.

Completely agree. I posted earlier this has a similar track as December 5/6 2009 with rain and white rain on the coast and snow inland. 

Unfortunately I had to witness this over and over again growing up in the 80s and 90s lol. Warm wet/cold dry. Good setup for the Middle Atlantic and great lakes though! 

[SACRUS]

37 / 24 mainly clear.  Dec opening cold and continuing at least the first 7 - 10 days.  Overall colder to much below normal through the 11th (at least).  Trough into the east with deeper cold Dec 4 - 9th.  Perhaps one sub freezing day even to the coast on Fri/Sat.  Would be surprised to not get above normal Dec snowfall this month.

No injuries were reported from the wind, but a number of injuries were reported from those helping with the cleanup effort.

Not gonna happen cause it went poof. Bluewave is right. We either get cutters/coastal huggers like Tues, or when the actual cold is in place like this weekend, suppressed tracks. The atmosphere in the 2020s is finding every way to not track a low up the benchmark when there's cold air around in the east. It's like a lesson in how to not get snow

Its December 1 for crying out loud.

[Brian5671]

People expect too much-they see -NAO or this or that and think December 2003 is coming.   Those months are exceedingly rare.    It's simply too early for snow especially for 75% of this forum

I believe its a function of not living through the lean years prior to 2000. People expect the bonanza of snowstorms during that time and get frustrated when we regress back to the mean.

[psv88]

Still some hope that Friday/Saturday event gives us something

Sure. But we already see the pattern unfolding. huggers and suppressed, the dominant pattern since 2018.

The last few years is not the norm however either. We swung very hard in the other direction. 2022-2024 was the first central park saw back to back single digit " winters. It's unfortunate now that we can't get moderate yearly snowfalls in the 20"s like back in the 1980s. The default now is single digits or in the low teens" with rare exceptions like february 2021.

Been beyond hideous outside of Jan 2022 and the winter of 20-21 that's for sure...

You can see into the future past this month? The MJO haven't even went into phase 8.

Its too early to give up on that one. Lets see what the models do once tomorrow's storm leaves.

I think the look has gone more suppressive for sure in the 12/6-12/12 period.  I think after that the pattern could go active again but that period may be quiet across most of the country.
