January thaw? -
December 14th - Snow showers or Plowable snow?
CoastalWx replied to Sey-Mour Snow's topic in New England
A lot of those events just didn’t have the confluence that we have with this one. It would start out as a wave moving off of NC and just tickle NW each run. -

No man, all would not like an ice storm Christmas. I'll drive in the snow and be fine with that. But driving in ice is a absolute no! And I would venture to guess that a lot of us travel either Christmas Eve or Christmas day. But I'll be sure to put a good word into mother nature to make sure you have a good ice storm right in your hood. -
When someone says we all would, It really means he would.

That was freaking ravaging.

December 2025 Short/Medium Range Forecast Thread
jaxjagman replied to John1122's topic in Tennessee Valley
Just saying, here in Mid Tn,during NINO'S we can have destructive ice storms compared to NINA.Its really rare in a NINO winter to not see ZR or IP fall underneath SN and not just all SN.We've had in the past I.E in the 50's and 90's some destructive ice storms in MID TN.,during a NINO,for what ever reason NINA seems to bring late season snow here that falls at night/early morning and melts during the day,this is always late into winter early spring.But i'm not saying it cant snow,its winter,just the odds are it might not happen -
Today’s GEFS PNA forecast is the most negative for this Dec that I can recall: This implies the realistic chance for a sub -1 Dec PNA. Whereas that’s bad news for those wanting E US cold in the 2nd half of Dec in the MidAtlantic/OH Valley south, it isn’t necessarily bad news for January prospects. That’s because in the vast majority of cases for -ENSO, the PNA in January rose sharply from Dec: PNA Dec/Jan for -ENSO for strongly -PNA in Dec - 1955-6: -2.1/-1.3 (rose 0.8) - 1961-2: -1.2/-0.1 (rose 1.1) - 1964-5: -1.7/-0.2 (rose 1.5) - 1971-2: -1.5/-1.4 (rose 0.1) - 1984-5: -1.6/+1.6 (rose 3.2) - 1996-7: -1.2/+0.6 (rose 1.8) - 2008-9: -1.4/+0.6 (rose 2.0) - 2010-1: -1.8/+1.3 (rose 3.1) - 2012-3: -1.0/+0.6 (rose 1.6) - 2013-4: -0.9/+1.0 (rose 1.9) - 2021-2: -1.6/+1.0 (rose 2.6) So, average PNA rise Dec to Jan for these was a whopping 1.8! Dec temperature anomalies: coldest N Rockies to N Plains/mild much of SE 1/3: Jan temp. anomalies: coldest shifts 1,000 miles SE and warmth gone https://www.cpc.ncep.noaa.gov/products/precip/CWlink/pna/norm.pna.monthly.b5001.current.ascii.table

NBM/SREF adjustments it looks like. Those are the only things that got drier to my knowledge.

Those were absolutely rotten winters. Even the snowstorm that followed in January 2016 couldn't save the 2015-2016 winter.

December 2025 Short/Medium Range Forecast Thread
Carvers Gap replied to John1122's topic in Tennessee Valley
Two different models, and BIG differences for our back yards as a result. The 12z GFS has a cold front on Christmas Eve. The 12z Euro...not so much. The difference? The Euro has a much deeper area of BN heights in the eastern Pac (which originated on the NA continent...I guess that could happen but I am no holding my breath). Conversely, the GFS slides an area of BN heights over the GL(versus dumping it all into the Pac), and a strong cold front results over our region. Look at the difference in the ridge over NA. Below is a nearer term difference. This time the 12z Euro has a cold front over the East on Dec 20th. The AIFS, CMC, and ICON all have this. The GFS is the outlier. The ridge and trough locations are exactly the opposite next Friday. The GFS somehow loses energy heading East. The results are polar opposites. All of this is to say that small differences over the eastern Pacific are having huge downstream impacts. In some cases, we are seeing 50-60 degree swings in modeling. And I feel like I have typed that before...maybe later November? I do think we see some Chinook winds. That seems almost inescapable as SLPs transit the Rockies. But cold air "should" cave behind the low as it passes. Our advantage this years is that big green blob in northern Canada which recent climo had as AN heights - ie. we have a cold air source. I also think ensembles are washing things out due to the means. IF(stress) we are seeing feedback which is amping ridges in the east too much, then the average temp of all members is going to be very skewed. Things get washed out. IMO, a very back and forth, amplified pattern "could" be coming up as an alternative to the torch. If we can swing a trough through on the 20th and on Christmas Eve, that is tolerable? -

yeah, not really a torch pattern with the -WPO encroaching into AK and the TPV elongated like that. sure, it's a torch for 75% of the CONUS, but who cares -
