January 2026 OBS and Discussion

Looks nice and cold in the long range. CMC and GFS have something around the 22nd, looks like a SWFE which would favor New England of course.

God gfs is such a weenie model

GFS is shades of the often forgotten January 2018 coastal blizzard. Close to 2 feet and hours of legit blizzard conditions in Point Pleasant Beach that day.

Maintain the view of a more active southern stream with cold air nosing into the northern tier and potentially into the midcon.  MLK weekend is the start of our best pattern potential for higher impact snow storms in quite some time. 

 

Pieces are on the board, it's a matter of putting them together.

15 day warm up is not a thaw. A thaw is like 3-5 days. 15 days is half the month!

Yeah, numerous spots out West and in the Plains are over +10 so far. This was a pretty big miss from the model forecasts issued around Christmas. Models have really been underestimating the ridge from the West into the Plains this winter beyond 7 days out.

Around 12/27 or so this board and other boards and a host of heavyweight professional meteorologists were posting (somewhat giddily by some) about how amazing the pattern looked for cold and probably snow for the next 2+ weeks.  Most of the good ones said this simply increased the probability of snow, but was no guarantee of it, as predicting that far in advance always comes with significant uncertainty and such patterns don't always verify.  And unfortunately most of us got some pretty cold weather for a week or so and then saw a warm-up that hasn't quite ended yet and very little snow.  

I'm not posting this to be critical, but I am curious what some of our pros/trusted folks would say about the level of confidence they might have for what looks to be a cold and potentially snowy pattern ahead for the last week in January and maybe beyond vs. the level of confidence they might have had back in late December.  

My thinking was as follows:

December 27: Below normal temperatures will continue into at least the middle of the first week of January. Some flurries or snow showers are possible late on January 1 into January 2. 
December 31: The first week of January will likely have a mean temperature below 30° in New York City. The last time that happened was in 2018. The only years since 2000 with a sub-30° mean temperature for the opening week of January were 2001, 2010, 2014 and 2018. 
January 1: Milder weather could develop on or around January 7th. The milder period appears likely to last for about a week, but there is some uncertainty about its duration. Afterward, conditions could become more favorable for both cold and snowfall, especially if the PNA goes positive. 
January 6: No significant Arctic blasts or significant snowfalls are likely through at least mid-January. 

Verification:
1) The first week of January was somewhat warmer than I had anticipated overall. It was still the coldest opening week to January in New York City since 2018.
2) Snowfall totals were light. That's often the case with a predominant PNA- pattern. For December-January, moderate or larger snowstorms typically have a PNA+.
3) Warm anomalies developed a few days earlier than my thinking (January 5th vs. January 7th). Today (January 14th) will likely be the last day with warm anomalies before the onset of a colder pattern. 
4) While Arctic air could begin to get involved next week, it appears virtually certain that there will be no moderate or significant snowfalls through January 15th.
Going forward, the ensembles continue to evolve toward affirming a predominantly PNA+ pattern. That, in combination with an AO-, has a much higher than climatological frequency of moderate or significant snowfalls. The actual synoptic details will be crucial in determining whether the increased potential will be realized.

Going Forward: January 16-February 10:

I suspect that the combination of the AO-/PNA+ and potential re-emergence of an active subtropical jet kicked off by a possible westerly wind burst (WWB) in the Pacific will be conducive to opportunities for snowfall during the second half of January through at least the first 10 days of February. That includes the chance for a moderate or significant snowfall. However, one will need to watch the synoptic details and how things come together. Overall, my confidence for snowfall for this period is notably higher than it was for the first half of January.

Yeah, it's been incredibly warm and dry across West and Plains this "winter." The only wintry weather has been from North Dakota through Midwest to Northeast. We are all falling behind average snow. Very mild January thus far for entire US

Euro has a cutter for 22nd-25th period where other models show a SWFE.

I guess in a bright note (for those who like cold) the January thaw looks like it ends today, CPK will be approx 40 tomorrow.

Finally. We went above average on 1/6 and have been like +10 since then. 8 days

The worst one in my life was 1991 we actually wore short sleeves for a few days lol.

Actually it was February 1991. 

January 1991 was +10 for 10 days during the month.

February 1991 hit 60 degrees or warmer 5 days! 50 plus 11 days!
