Extended at least offers hope. Definitely has that moisture out of the gulf look. And overall cold. That 20th event though could be mild...definitely a risk.

yes .. because it's a -epo load preceding that amplitude ... which, that's really wobbly where the trough axis really ends up.  could easily back up relative to the flow.

It's 25ºF here in Charlotte but the super bright/strong/blistering early January sun is melting my snow.  I was surprised to hear the infernal drip-drip-dripping when I went on the porch a few minutes ago.  When there is less than 0.1" water content in a 4" snowpack, what the sublimation does not kill, a 25º sunny day will.....

European and British calculations figure with a cooling La Niña instead of last year's warming El Niño, 2025 is likely to be not quite as hot as 2024. They predict it will turn out to be the third-warmest. However, the first six days of January—despite frigid temperatures in the U.S. East—averaged slightly warmer and are the hottest start to a year yet, according to Copernicus data.

Congrats Earth, we did it again.

personally ... their reasoning is sus to me a little.

i mean, 2023 with the pan-dimensional thermal burst ...which apparently, never receded... actually took place pre- NINO/ENSO state...  so, that tells me that whatever that was, was quite logically not really occurring because' of NINO - there may have been some back and forth augmentation/superposition thereafter, but the thermal burst buries NINO somewhere inside.  

if that is true, not sure NINA/ENSO is going to be so readily quantitative in the end results, either.  

this is just how this all looks logically, to me.  i'm not sure what mathematics they use to come to the idea that NINO/ENSO's warming led to 2024 - but perhaps it's something like    2023 + (2023 + NINO) = 2024

so 2025 is 2023 + (2023 + NINO) - (2024 + NINA)  ... :wacko2:

Never got above 27 here today, staring at my 1 inch glacier and sad snow piles in the yard. I hope we can squeeze at least an inch tomorrow and maybe Tuesday ends up popping for us. If we get rain next week I'm selling and moving to Lab city. Finally move back north and can snowmobile out of my garage door and had the worst possible snow seasons since I did...

What's that feeling like? To wake up and look out the window and go: "damn it snowed again!".

I honestly can't remember the last time I woke up in the morning and was surprised by the amount of snow we go overnight. January 2015 maybe

It happened here in the Valley last week.  3" of subcritical flow fluff with the inversion below the ridgetops to the east.  First time in a *VERY* long time.  Just missed out yesterday as well.  I got 0.5" but when I went to the gym 12 miles away, it was 4" of surprise fluff that just never shut off all day.  The BTV snow machine is interesting in these NW flow regimes when there is a cutoff to the NE.

You didn't ask me but what has me spooked for winter enthusiasm are these inferences, perhaps compounding one another:

A:  Yeah, the MJO desk is echoing those Weeklies - so it would seem. Whether they have seen them or not it is unclear if they are incorporating them into their present outlook philosophy - they defer to just a linear correlation to wave spacing   "...• While below-normal temperatures are forecast across much of the central and eastern U.S. in the near-term, the strengthening MJO across the Indian Ocean historically favors a warm extratropical response over the U.S., and a pattern reversal toward warmer temperatures could begin toward the end of the month or in early February..."

B:   La Nina's are statistically correlated to warmer Februaries.  This is "field-presumptive," admittedly. If anyone has qualitative information I will not take it as refutation - be my guest.        And obviously, like all inference techniques ... the interpretation should be used in the spirit of "tendency"

C:   The last 10 years of eastern continental climatology has verified very usually, at times 'shockingly so' is not a poor adjective, warm excursions in February's.   We're not talking the thaw times of lore, with one or two days into the upper 50s or low 60s and a continental snow line retreat exposing one or two eager Crockus shoots of lore.   These events featured temperatures of June east of the Apps cordillera soaring past 75 reaching 80 between D.C. and PWM.   They were historic setting numbers,  of course, but what is of more importance to me is that it happened multiple years out of the past decade - regardless of ENSOs...   And we may as well include the March 'heat bursts' that were of equal anomaly in this group.  This to me should not be ignored.

SO...

(A + B + C ) / 3   = ?

...just summing the concepts and dividing for the mean, in this case,  should be a red flag ( perhaps a pun there?)

Having said all that. I'm not sure the MJO desk has their part of this quite right.   I was looking over the temperature composites for the RMM, and they are pretty cold through phase 3 - which is still two weeks away - and it's not clear whether the wave will be robust in 4 from this far away in time.  Maybe they have some early non-zero confidence for the temporal horizon. who knows.

Caveat with this being your point about ENSO being less coupled with the atmosphere....we have certainly seen it this year with the WWB erupting in late Novie to kick off the extended PNA regime that we have been in. Not to mention this La Niña is very meager to begin with....weak ENSO are more prone to other influences, anyway, aside from any CC inference RE difficulty coupling.

Seems colder in the Northeast thanks to the wind.  Also clouds and daily max temps - here they're running 3.7° BN this month while mins are +4.5.

CC in a nutshell....much larger impact on daily mins than maxes....not to imply it does't impact maxes at all because it certainly does.
