December 2025 Short/Medium Range Forecast Thread
Carvers Gap replied to John1122's topic in Tennessee Valley
Now that I am back and things have settled down a bit, here are a thought or two... 1. Recent Nina winters have followed a fairly predictable pattern. Cold end to November, cold start December, flip to warm around Christmas. and cold returns for late Jan and Feb, especially middle and western areas of the forum. 2. I don't trust models right now past ten days - if that. There has been a lot of feedback in the usual places. So, pivot back to point number one.... 3. To me, the real question is whether we get one final cold shot right before Christmas - 50/50 for me on that one. I think the warm-up after Christmas has been well advertised. We know how the last warm-up worked out - cold. Let's see how this one goes. 4. There are things to track prior to Christmas. I see roughly (4) windows to monitor. I will try to dig a bit deeper later. I got 0z, 6z, and 12z to look back through. Tomorrow is gonna be even crazier. -

BTW, Larry's idea is that winter's worst is from late January into March...and rough at that. Gotta run. Sorry, I hadn't posted much this morning. Dear Facebook, as I was pulling out of the garage I ran over a can full of blue paint. It exploded under my truck. I didn't know it until I drove around my cul de sac - twice! I got to scrub lots of asphalt and the garage floor. Meanwhile, I had to do a NASCAR fast wash down of the truck in order to get it on the road for one of my kids. Anyway, BN heights(aqua blue...don't even get me started on how that color wound up in paint storage) went all over the place!!! Maybe it is some kind of sign. Trust me, I would rather be looking at raging warm weather models. Haha. Don't have sympathy. Just know if you are having that kind of day...you are not alone!!! -

OTH, if January and Feb got to pot....my winter forecast from June scores yet again. LOL. FTR, I hope it doesn't verify. I think Larry Cosgrove nailed this seasonal outlook with the exception of the first 2.5 weeks of December being cold. I strongly encourage everyone to find him on FB and read that seasonal outlook. He has been zigging while everyone else has been zagging. If he is right, and I have no reason to think he isn't, we will all be happy by the end of Feb. But as Larry noted, patience will be king this winter. Just imagine this pattern, but with January cold forcing its way southeast. What happens in November(and early December), the winter often remembers. -

Cancel winter at your own peril on Dec 9th. It's a Mid Atlantic forum tradition which I don't partake in. Also, remember when I "canceled" the cold to start December? How well did that work out? I do think we see some warmth after the 20th. Is it a pattern change? It could be, but a 2-3 week pattern relaxation seems about right. The 12z Euro actually looks decent. Cold to the end of the run. The MJO is all over the place. I think there is convection in a lot of areas which is producing conflicting signals. John noted that yesterday. The plots at CPC are to the left of center, but chose your own adventure. The MJO has managed to loop back barely to 7 in the COD. I would guess it comes back around to 8. It normally goes counter clockwise. Why? Because the weather moves from west to east. Unless that changes, it doesn't really make long term transits in reverse. And my broken record advice...climatology does not support much snow at this time of year in the valleys. Enjoy being in the game in early December - that is a bonus for all bu the 1960s and a handle of winters since then. FTR, I have sat through many early December Christmas parade in short sleeves! -

Fortunate indeed! I remember walking through the neighborhood and just listening to the wind how as very fine snow was falling. Fun evening. -

I have shrubs that finally recovered this season!!! They got absolutely scorched. -

In TRI, that would be 0.5" of ice preceding 10-12" of snow. Give me the snow...I don't want any ice. Slow-ish moving wave. If it was closer, I would post maps. -

Real temps behind that fall to -10F in some places and -20F for WCs. Fun run. Unlikely we see that every run, but fun! -

Lets try that again, and this time NOT in centimeters. In my haste I clicked centimeters. Up to 30" of 10:1 snow. Most assuredly, if that wasn't Digital snow, that would be much more due to higher rates due to colder air. 40" Kuchera in W VA. -

It would make a lot of sense if the pattern was about to break for warm...for that blizzard to show in exactly that spot. The GFS has held to that since yesterday. I would encourage everyone to not get their hopes up. I actually don't like tracking Christmas systems since so many get their hopes up. But I really want to see the GFS hit this from day 16. Also, do remember that systems are often lost between d5-7. Let's get that out of the way now. LOL. -

That is a blizzard. Wow. It will assuredly change, but the 18z has a full fledged blizzard after 300. -

The 18z GFS has two "mood flake" systems, and one boomer. Plenty to track for December. -

Really, the pattern right now is cold, reload, and more cold. That might end later in December. -

The 18z GFS has the anafront again. Gonna be wild if it hits from d16. Seems like it hit that Christmas Eve anafront(from a few years back) at the same range. -

Currently snow is falling in west Kingsport. A little band has been set up. Just barely missed today.
