    It was kind of rare to have that SE ridge with such a pattern over the Arctic and North Pacific I think the +NAO was actually the reason - that big negative anomaly exceed -400dm south of Greenland, that has less to do with ENSO

    ^Vs the 61-90 average seems a little weird.

    Low pressure over the N. Pacific favors east coast troughing though. Of course if the negative anomaly spills into the West coast like 82-83 and 97-98, that pushes everything east. +AO kind of dominated the pattern in 82-83 though.

    This may surprise some people - Nino 4 is neutral in trend since mid-April

    They just had a good snow event in the mountains of Montana!

    I think the Arctic cold this warm season will serve as a catalyst to keep the PDO more negative in comparison to ENSO this year. It's a pattern. Still have July-Sept to go though, so it could change, but since the Solar Max it's been a pretty sustained Summer +AO pattern.

    I also had a 7" and 11" storm last Winter. If it wasn't 14 degrees and sleet, the Jan storm could have been 20"+. Sometimes exact snowfall numbers are taken too literally regarding possibility and potential
  8. Stormchaserchuck1
    Flow can be more NW -> SE in the cold part of Nina's, so threading the needle is possible on the coast. +ENSO tends to be more borderline in wintery events, favoring I-95 or NW, as a trough digs to our west with storms.

    Cold ENSO/Strong -QBO gave us a cold December last year too. 2021 was the exception, but it works in reverse too (cold ENSO/-QBO is cold). Even in Dec 2021 there was a >+300dm block in the N. Pacific. Move that 250 miles NE and it would have been cold. Of course the Nov Stratosphere warming last year was the reason.

    The difference between Weak vs Moderate vs Strong vs Super Nino is the same. In weaker events, the ENSO signal is weaker so other things dominate more, more randomness. Caveat being that East vs West based event does make a difference.

    I think the PDO may start to trend positive decadally when the Summer Arctic ice catches up with its previous trend or starts "evening out all this warm season cold anomaly". What do you think @40/70 Benchmark?
  12. Stormchaserchuck1
    The odds of a cold Winter at all in the mean (DJFM) is probably like 15%. For the US as a whole maybe 10%. It's not a hard forecast.
  13. Stormchaserchuck1
    I think El Nino's in general are colder than people think in the US Winter. Caveat being that Nino 1+2 dominating and being like +4c could be pretty warm, at least in the NW 1/2 of the country.
  14. Stormchaserchuck1
    That's a good point about the North Pacific and -PDO. You can see the clear correlation here But how impressive is that low pressure anomaly over Arctic for 11 warm seasons now (2019 was the exception)!
  15. Stormchaserchuck1
    Summer cold in the Arctic since the 2012 arctic ice melt low has really been phenomenal! Anyone want to offer a theory on why that is?

    Baltimore city forecast Thursday Sunny and hot, with a high near 106. Thursday Night Mostly clear, with a low around 81. Friday A slight chance of showers and thunderstorms. Sunny and hot, with a high near 106. Chance of precipitation is 20%.
  17. Stormchaserchuck1
    Good chance for an -AO this Winter in my opinion! The correlation to reverse conditions there between the warm and cold seasons has been strong since 2012! I think the period looked at is through September though.
  18. Stormchaserchuck1
    That's the NAO. I think the folder code is always pna. Here's PNA: cpc.ncep.noaa.gov/products/precip/CWlink/pna/norm.pna.monthly.b5001.current.ascii.table
  19. Stormchaserchuck1
    09-10 was big +PNA. It was actually +PNA every month from June 2009 to April 2010
  20. Stormchaserchuck1
    Do we make it 6 months in a row of -PNA? 5940dm block over the PNA region is not a typical El Nino pattern. We aren't seeing that El Nino low pressure in the North Pacific at all, although at times US and Europe conditions have been close match.
  21. Stormchaserchuck1
    Historic heat wave in Europe has correlation to ENSO
  22. Stormchaserchuck1
    It looks like +9C is about to pop in the subsurface on TAO/Triton!
  23. Stormchaserchuck1
    I wonder if Summer ridging at 90N is something that reverses long term, "evens out", like ENSO seems to do? We have been in a long, consistent cold period since 2016.
  24. Stormchaserchuck1
    PDO is glaring there, look at this a -0.6 correlation in Louisiana! That's out of 1.0. I would agree, near normal, El Nino east or west based is usually colder than average there
  25. Stormchaserchuck1
    Check out how Nino 1+2 being warm (+2.8c) is hitting +correlation in the Rockies in the medium range.. means you might have to give warm Nino 1+2 analogs credence going forward The Rockies in the Summer recently have almost never seen that kind of cold. That's vs the 81-10 average
