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!

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.
