Congrats

Not sure why you posted it again. You could have waited for the ND update, which is probably next week.

-1.2 peak in SO, ON was up to -1.1.

Yeah, I posted on Dec 9 that the MEI updated:

A large portion of the West had their warmest December on record. But none of the areas in the East that were cold approached their coldest December on record. This has been a common theme in recent years with the warm departures being more impressive than the cold departures on a month to month basis.

December 2025 temperature ranking (since 1895). A lot of the West had their warmest December on record and nearly everywhere out west had a top 5 warmest December.

The month-to-date temperature departure from normal for the Contiguous U.S. is +3.9F. If this is how the month ends, December 2025 would finish as the 4th warmest December on record (1895-present). 4 of the top 5 would include 2021, 2023, 2024, and 2025. It's as if something has changed.

lol, this looks more like an el nino or a +PDO than a typical -ENSO/-PDO.

those never work out. we would need a phase but those never worked out in my experience 

Yeah, the last time a clipper really worked out was the one in January 2005, which turned into a Nor'easter.

Forgot about 2000 that was -9.7F

And December 2005 with 14"

That happens in just about any la nina December in years ending in 5 or 0. 1995, 2000, 2005, and 2010 were all very cold and snowy Decembers. Even 2020, which was near normal temperaturewise, had a big snowstorm in the middle of the month.

As noted in the general ENSO 2025-2026 thread, the forecast development WPO+/EPO+/AO-/PNA+ pattern typically does not favor large East Coast snowstorms during January 1-10. Instead, lighter snows are the rule. 

If we don't have a good snowstorm in January 1-10, we might be waiting a long time for one. Maybe even until next year. Remember, we've had below average temperatures for most of the time since August. It's only a matter of time before it swings back the other way, and we have above average temperature departures. And once we have that, the chances of snow will be tougher.

Yep, that storm is king for me of sheer intensity and thunder snow that morning. 

The January 26-27, 2011 snowstorm compares. That was an overnight snow, but I remember the intense thunder snow keeping me awake.

Ouch, March 29, 2025 wins the game!

That was the best weather day of the year. I'm sure everyone enjoyed it, well except MJO812. Bring on 80s and sunny any day over the slop we got this weekend.

Sometimes guidance can correctly latch onto big cold blasts or warmups far in the distance. I remember how well the January 2019 cold blast and early February 2019 cold blast was forecast. Got down to near 0 here in NYC. Down near -30 in Chicago. Very impressive cold blasts that winter 

That was the last real cold blast in the Eastern US. That was also the only winter in the last decade (since 2015-16) that didn't have a uber warm (+5.0 temperature departure) month in the November-March period.

If we don't get a torch month in January, February, or March, we would really be bucking a trend.

I also can't get out was counting on the ice driveway on a steep hill melting. May be the first time iced in since 1994

I was iced last January, as well as in late February/early March 2015.

In February 1983, we still had a few inches of icy snow left from a moderate snowfall the week before the blizzard.  Of course the melt out following the blizzard was epic.  Excellent lasting snowpack in both 2014 and 2015. Even 2001 was decent.

A shame how the 2001 season ended. The March snow bust really drags that year down because that's the lasting moment everyone remembers from that winter. If the snow bust happened on December 30 (2000) and the major storm happened in early March 2001, no one would care about the snow bust, and everyone would be talking about how 2001 was a decent winter.

Can you imagine what a heating bill would look like these days with a mean monthly temp of 25?   Have to believe it would cause hardship for many.

We don't even need to go back that far to get a mean monthly temp of 25. That happened in February 2015, part of a 3-month period (January-March 2015) that was the coldest post-1980.

Thank god that’s over. Just a brutal storm to track and experience. My least favorite in recent memory.

As I've said all along, 80 and sunny doesn't seem so bad after all.

Thanks for posting data like this. 25 mean temp in 1876 is wild. 

We also had 25 mean temp in Dec 1989, but then we had 40-41 mean temps in Jan and Feb (1990), and 46 mean temp in March.

13-14 definitely was a good December too iirc. No biggies but several nickle and dimes.

Great wall-to-wall winter, actually. Technically, 17-18 and 20-21 also had above average December snowfall.

You said the same thing about December .

January is looking very wintry. 

Never said that about December. I've said these type of years tend to have cool Decembers in the East, but very warm Januarys and Februarys.

The beginning of January may be cold, but I can pretty much guarantee you that we won't go all the way through the month cold. That doesn't happen anymore, let alone in a -ENSO/-PDO/-IOD winter. Even in January 2018, the pattern flipped warmer in the East during the 2nd half of the month.

54 minutes ago, SnoSki14 said:

Interesting to see if that works out. Pattern does have potential heading forward 

Problem is this is still a -ENSO/-PDO/-IOD winter. Those types of winters don't cold all the way through December and January, unless you have a relaxed Pacific Jet (like 2010-11), and we don't have that this year. If it was a +ENSO/+PDO (like 2014-15), I'd be easily predicting a cold and snowy January.

I think January will turn warm, at least be a near normal, or even above average temperature departure.

We can hope.

No way we have to wait until Jan 19 as per drought man. Models are starting to hint at some threats first 10 days of January, one of which being a legit Miller A (as depicted currently that will probably change). 

If we don't get one by January 19, then we're going to have to wait a long time for the next snowstorm. I get the feeling we're going to see above average temperatures by the time we hit mid-January. -ENSO/-PDO/-IOD years don't go all the way through December and January cold. That's something that happens in a +ENSO or +PDO winter.

I just got home from my train to Babylon, easily 4”. Reading this thread at my job, I was shocked. I thought it was 60 and sunny out. 

I can't wait for days when it's 80 and sunny out. March 29 was easily the best weather day of this year.

NYC people...remind me again what this 4" snow record chase is? Longest without a calendar day 4" snowfall?

NYC has not had a 4" snowfall since the January 28-29, 2022 snowstorm.

If this event is going to follow a classic, canonical “front-loaded” La Niña, i.e. 2010-11, the eastern cold/snowy pattern usually starts breaking down by late January and February flips above normal. So far, since late November, this event has been totally consistent with front-loaded, canonical Nina’s of the past 

Thing is, 2010-11 had a very relaxed Pacific jet (we haven't had that since 2013-15). That's why December and January went all the way through cold. And the west wasn't really that warm in 10-11 (like we had in 13-14 and 14-15).

Without a relaxed Pacific jet, I expect things to torch at some point in January. Coldest case scenario is January 2018, which was near normal. February is going to torch. (Sorry for those who love cold, but that's how -ENSO/-PDO/-IOD years tend to work. You just have to hope that winter returns in March. That did happen in 2017 and 2018, and even to a lesser extent, the last week of March 2011.)

With the clouds, low DP, breeze...not bad at all out there."

"80F"

"Had a couple raindrops then a pretty cool sunset.

Maybe some showers late tonight / early morning? 

74F/ breezy"

My estimate is for Chicago to end up Dec 3 BN, Cinci 2.5 BN, Balt. 4.5 BN, Philly 4 BN, NYC 5 BN, and Boston 4.5 BN.  Even the upper SE (NC) should come in slightly BN and then ~+1.5 at ATL. SL should be right at normal. DFW should be ~5 AN, DEN ~11 AN, Phoenix 6.5 AN, LA 3 AN and Seattle 4.5 AN.

Temperature departures like this is something you see in a +ENSO or +PDO season, not a -ENSO/-PDO/-IOD. There is definitely going to be a pattern change in January. At a minimum, either the Western US will turn cold or the Eastern US will turn warm.

Rooting for nyc to cash in so then we can all win come January. 

That has no correlation. NYC cashing in on a snowstorm doesn't mean everyone is going to win come January. For all we know, DC could end up with a final season snow total of 3-4" (see below).

That depends on where you were.  Places well north and west of the city did get a heavy snow event with this one.  Allentown had 17”.  Places in upstate NY measured into the feet. 

That season had one of the oddest snow distributions ever. Places in upstate NY finished the season with over 150 inches of snow, while places like Baltimore and DC finished with less than 4 inches of snow.
