    It did not the SPV was stronger to start than this past year but had a very similar large wave 1 like this past year about a month apart from each other. 25-26 November while 23-24 had it in December. Look at the difference leading into both SSW events at 500mb. 23-24 had an atmospheric pattern at 500mb not conducive to sustain the ridging like we would want to see. 25-26 set it up and finally connected in the Nov-Dec 500mb pattern which is exactly what we would want to see occur. Both had very similar Stratospheric ridging patterns but very different 500mb patterns existed thus leading to different results. Both years were in deeply negative PDO territory rising as we got to winter, this past year was some lowest numbers recorded. Both years had a -QBO state at 30mb and were descending (2023 was a tad bit later but still negative during these times). You could make the argument that this past year had more of an El Nino kick to the atmosphere than the year where we had a strong/super Nino.

    January 2024 had a -NAO and some cold. The -NAO kept linking up with SE ridge 2018- March 2023, then in Jan 2024 it started to occur with more of an East coast trough, and the same -NAO/EC trough pattern has happened 24-25 and 25-26.

    Actually recently Stratosphere warmings have been the anti-thesis: 23-24 had 4 separate Stratosphere warmings and a warm 10mb for the Winter and was the warmest winter on record for CONUS. March 2026 had a Stratosphere warming in the first half of the month, and that was the most extreme warm air temp anomaly month ever recorded for CONUS. The Nov 2025 Stratosphere warming preceding cold is actually the counter trend to what we've seen in the last 3 years, although I know Gawx posted some interesting things when it happened like 9/9 following January's are colder than average. Cold Winter Stratosphere's have correlated with more +AO's in the last 5-6 years, so that part is working.. but March 2025 and March 2026 did not have SSW impacts at all on the NAO.

    Is “WP” (monthly table) the same as “WPO” (dailies, which we know were negative most of the winter)? That table has positives in each of D, J, and F! Can’t be the same thing! It has +.08, +.07, and +0.23 lmao.

    Chuck, I think I do recall some blocking during 2023-2024 now.....I remember Chris going on about how the se ridge was adjoining the NAO blocks that season, which is what killed us....likely a byproduct of the cool ENSO residue that persisted that season (RONI lagging ONI).
  7. 40/70 Benchmark
    Just harkens back to my point about the monthly tabular readings not providing an accurate portray all of the time.....you need to view the dailies because there were significant -WPO intervals this season, which is why it was so cold with more snow.

    Dec daily WPO: every day was negative and yet that table has +0.08. So, that table is looking at something else. The monthly table url has “wp” in it. Is “wp” the same as “WPO”? 2025 12 01 -163.44 2025 12 02 -139.59 2025 12 03 -103.12 2025 12 04 -115.00 2025 12 05 -37.98 2025 12 06 -31.37 2025 12 07 -48.33 2025 12 08 -84.47 2025 12 09 -106.99 2025 12 10 -130.04 2025 12 11 -192.25 2025 12 12 -316.04 2025 12 13 -347.69 2025 12 14 -304.25 2025 12 15 -259.07 2025 12 16 -205.71 2025 12 17 -191.49 2025 12 18 -190.96 2025 12 19 -200.61 2025 12 20 -183.89 2025 12 21 -135.08 2025 12 22 -127.59 2025 12 23 -138.14 2025 12 24 -130.99 2025 12 25 -113.55 2025 12 26 -107.01 2025 12 27 -95.19 2025 12 28 -71.08 2025 12 29 -82.61 2025 12 30 -127.57 2025 12 31 -123.82 https://downloads.psl.noaa.gov/Public/map/teleconnections/wpo.reanalysis.t10trunc.1948-present.txt

    Well, I’ll put it this way. That table of monthlies isn’t even close to what the avg of the dailies comes out to. Dec was -WPO every day. Also, Jan and Feb averaged -WPO. I crunched the numbers. link to daily WPO: https://downloads.psl.noaa.gov/Public/map/teleconnections/wpo.reanalysis.t10trunc.1948-present.txt
  10. Stormchaserchuck1
    Actually I can see it after going over the maps.. the slight + reading was correct because of further SW
  11. 40/70 Benchmark
    I understand that, but I simply didn't recall them...probably because they were useless.
  12. 40/70 Benchmark
    I felt like it did, too, so the monthly numbers are incorrect?
  13. 40/70 Benchmark
    It doesn't make sense to me, either...but those are the numbers.
  14. Stormchaserchuck1
    No way December was +WPO
  15. GaWx
    According to the average of the daily WPOs at the link below, it certainly did average a -WPO this winter: https://downloads.psl.noaa.gov/Public/map/teleconnections/wpo.reanalysis.t10trunc.1948-present.txt

    23-24 had 4 separate Stratosphere warmings. They don't always mean cold - actually the composite mean of top 20 warm 10mb Winters (Nov-March) is above average temps in the Northeast, US. Biggest pattern is shorter term lagged -NAO with peaks, which can occur +months early in the cold season to +weeks mid/later in the cold season.

    Ray, Please provide your link to the monthly WPO. Something seems off. TIA
  19. 40/70 Benchmark
    2023 had an early late November/early December reversal??
  20. 40/70 Benchmark
    Ahhh...okay, thanks. This makes more sense, then. Chris is probably right.

    F the Celtics impressive win
  22. so_whats_happening
    I think 23-24 didn't pan out in the way we had hoped even given similar SSW styles to this past year was the SPV was just that much stronger that year so it needed quite a bit more to really knock it down. Again unfortunate but it is what it is sometimes.
  23. so_whats_happening
    We tend to box things in a lot with these oscillations which is unfortunate but understand why it is done.
  24. 40/70 Benchmark
    Interesting....the other two early reversals were 1981 and 1968...the latter featured strong blocking throughout the season and the former had a blocky January.

    @bluewave I was stunned to see that this past season actually averaged +WPO (.44 DJFM)...I would have bet my life that it was -WPO, but only March was. December, January and February were marginally +WPO, but essentially neutral. Now I feel better about my previous work connecting +WPO to the more active jet, as this makes more sense. We had more variability this season, which is why it wasn't strongly positive like previous years in recent memory...this allowed for the cold, but the +WPO in the mean continued to correlate to a more active jet, which is likely why we only saw one major coastal. The big January event was a huge SWFE.
