That April 1982 snowstorm showed just what could have been. If not for a long lull in February and March, 1981-82 could have been a historic snow season. But the April storm was a nice reminder of that cold and snowy pattern in January 1982.

Back in 2023-2024 there was a pretty big spread between ONI and RONI. The ONI peaked at +2.1 C and the RONI at +1.5 C .Yet the 500 mb pattern across the Northern Tier and Canada was similar to 1997-1998 with the CONUS setting the warmest winter on record.

Perhaps the weaker RONI was related to the lack of a robust Nino trough across Mid-Atlantic and Southeast and weaker Aleutian Low.

Plus we got a big global temperature super El Niño baseline jump even higher than 1997-1998 and 2015-2016. Also note the global temperatures hardly fell in 2025.

Global temperatures seem to bottom out around 1917 (following a super la nina), at about -0.2 lower than the 1850-1900 pre-industrial mean. If we use 1917 as the zero point, 1.5C would have been first breached in 2016, and the global temperature anomaly for 2024 would be at +1.8C.

What was that Easter in the 90s where it was warm and sunny and the next day we got like a foot of snow?

I believe it was 1997. I remember Easter Sunday, March 30, being warm. Then, it snowed on Monday (3/31) and Tuesday (4/1).

JFM 2026 RONI -0.7

JFM 2026 ONI -0.2

Stupid UConn women.  The men held up their part of the bargain (so far). Oh well, the living room's not that bad. 

 

I'm hoping that UCLA wins the Women's National Championship. This program last won a National Championship in 1978, before the Women's Tournament existed. Plus, Lauren Betts and the seniors deserve to end their careers with a title.

Need some serious CAA for the Park to go below 30 this late. Suburbs that radiate well are a different story

We did get close on May 9, 2020, and that was following a very warm and virtually snowless winter:

It's been like this since about March 8, a coast-to-coast torch.

I remember we got real wet at the end of Winter 22-23. It was foreshadowing the coming Nino. And 23-24 was wet like a Super Nino DJFM, but was really dry in November. 

The only time we got wet was the Nor'easter in the closing days of April, which brought a lot of rain the weekend of the 28th-30th. Other than that, late winter and spring 2023 was dry, with May being the driest on record. Late June and early July is when it got wet.

We have some pretty wild temperature swings coming in the next 3 days. All of these look to happen in the span of just a couple of hours.

Warm front tomorrow: 50s -> 70s

Backdoor cold front Saturday afternoon/evening: 80s -> 50s

Warm front Sunday morning: 40s -> 60s

Cold front Sunday afternoon: 60s -> 40s

Something weird is going on. I haven't seen this many temperature swings like this year. 20 degrees is normal, but there have been many 30, 40, and even one 50-degree swing so far. That isn't normal. I really hope this doesn't continue into the summer. I don't want it to be 100 degrees one day, and then 60 the next, in June or July. If I wanted this type of weather, I would move to Nebraska.

Where? Vermont? NH? Maine? Because there isn't any snow happening anywhere near here.

didn't they change the location though?  philly runs very high all the time.  rainshadow (Tony Gigi) who used to post here years ago and worked for mt holly for years still makes fun of their temps.  I'll take a real met over the wannabe's in here any day.  

The last time they changed location was late 1930s/early 1940s, I think. Before that, it was in Center City.

Do we then cool down after that warmup late next week, as has been the pattern?  Or do we get sustained warmth finally?  Have to wait until early next week to see what ensembles show IMO.  Takes some time to kick BDCF season around here.

The EURO shows sustained warmth coast-to-coast (see @bluewave's post in page 2). We've been in that pattern since early March.

The craziest thing is we were the cooler region compared to most of the country. The amount of +10-15 readings is insane. 

If that happens during June or July then it's gonna get ugly. 

If that happens, and the heat dome is centered somewhere around Death Valley, the American/global temperature record of 134 degrees could finally fall.

More chilly weather next week is fine with me but we can't spin up some kind of nighttime system with precipitation for an inch or two of wet snow? Should be plenty cold aloft. What a boring end to a really cool winter. I hope we get three weeks like tomorrow before the summer blow torch develops by Memorial Day. 

There hasn't been plenty cold aloft since at least early March. I was in Vermont for 3 days (March 7-9), and it was 55+ each day. I knew winter was essentially over at that point. And that's okay, as sometimes, the coolest winters end abruptly. Look at 2010 (after February) and 2015 (after March), for example. 2010 had (at the time, it was broken only 2 years later) the warmest spring on record, and 2015 had a near record warm May.

The Euro is also showing a torch pattern mid-month, coast-to-coast.

PHL was 84.

The way Nino 4 is warming is so interesting. Again, only 2 April's on record had higher than +0.500 monthly for later in year >+1.2 El Nino's (out of 15):

April 1997: +0.59

April 2015: +0.98

We are at +0.511 on April 1. There is so much warm potential energy for things to easily go strong. 

PhillyEaglesfan may not get his Strong Nina for a while. 

I wouldn't be too sure. After the 1997-98 event, a double-year strong la nina followed.

In case you haven't gotten it by now, winter is over: https://x.com/epawawx/status/2038305484810092870

No 90s the month as a whole was +1.5 -  +2 and highest was a 3 day strech of 80s mid april.  88 in EWR was the max

Then, there was a huge rainstorm the weekend after (which would have been a snowstorm if it happened earlier in the season).

This does not look accurate. 2025 should be there, not 2023. Plus, some of those months, off memory, I can tell you should have negative temperature departures.

The Euro is prone to being too warm with ONI, sometimes by a lot:

 It in 3/2014 predicted a +1.3 ONI for JAS vs only +0.1 that verified

It progged in 4/2014 +1.4 for ASO vs only +0.3 that verified

Euro progged in 5/2014 +1.5 for ASO vs only +0.3 that verified

It progged in 4/2012 +1.0 for ASO vs only +0.4 that verified

It progged in 5/2012 +1.0 for SON vs only +0.3 that verified

It progged in 6/2012 +1.2 for OND vs only +0.1 that verified

 

I’m not even talking about RONI, which as of now is ~0.5 cooler than ONI.

Yeah, they prematurely overhyped the el nino. But by the time you got to 14-15, you just knew whenever the el nino developed, it was going to be historic. The el nino was building up for 3-4 years at that time.

I'd even argue that 2024-25 was a la nina bust, as well. That one was predicted early on to be a strong la nina, but ended up as a disjointed 2-year la nina.

Agree. Still a wide range of possibilities given we are in early spring, but gun to head given the current subsurface im thinking it probably won’t be a weak event. Still, huge difference between say a moderate and a super Nino. 

A moderate el nino would be nice for a change. We haven't had a true one since 2002-03. Closest we had was 2006-07 (but that stalled at 0.9 on the ONI and RONI) and 2009-10 (but that went over 1.5).

Moderate el ninos seem to be the sweet spot for good winters in the Eastern US. The only one that didn't really pan out was 1994-95, but that was due to a -PDO, and even then, we got one good month of winter weather (February).

March is going to be the first widespread AN temperature month for Eastern US cities since September. October and November were NN, and of course, December, January, and February were solidly BN.

Well, this would be the first time we have had three consecutive -PDO El Nino events. If it did flip, I think it would go back after the El Nino subsides....I'm not saying the cold phase is over. I don't think that ends until beyond the turn of the decade.

Come to think of it, 2015-16 is the only el nino post 2002-03 that is a +PDO.

2004-05 -PDO

2006-07 -PDO

2009-10 neutral PDO (November December -PDO; January February +PDO)

2015-16 +PDO

2018-19 -PDO

2023-24 -PDO

If the PDO turns positive this year, then 1988 becomes the obvious anti-2026 log.

In the East, 1988 was a very warm summer, followed by a very cool fall.
