    Look familiar? These are our last two Dec 10-18's (2021, 2022) https://ibb.co/R3Pcbt3

    Actually, we had a strong -PNA Dec 10-18 each of the last two years. https://ibb.co/FmP0kb1 https://ibb.co/DQcP131 Current models have the -PNA again for Dec 10-18 this year.. this tendency toward continuum despite El Nino makes me think again we don't blow out February with +PNA, like a lot of people/models think

    Here's the 384hr prog though https://ibb.co/wKX9Krm It has some general accuracy Of course, that could always become a big -NAO for January
  4. Stormchaserchuck1
    The PNA stands for Pacific-North America, so it's partially calculated over our region. 1/3 of the PNA is in the N. Pacific, over the Aleutian islands in Alaska, 1/3 is on the West Coast, and 1/3 the East coast. Therefore, if the PNA like -3, that's because there's usually a ridge on the east coast downstream.

    EPS has never really been a good model imo. Do you know what they showed for Dec 10-18?
  6. Stormchaserchuck1
    Something about this wants to say sorry.. it's a strong La Nina pattern in an El Nino https://ibb.co/18hVZJQ https://ibb.co/Jj78d4n

    18z gfs has a pretty impressive Alaskan blizzard That cold around Greenland and Alaska at the surface is what I like to see for a gradual cold pattern.. cool source regions.

    Massive ridge over Scandinavia the last few runs.. let's see if it holds, I've noticed big shifts over the NAO region in the LR, doesn't always load when it's suppose to.
  9. Stormchaserchuck1
    not gonna lie.. I really like this pattern https://ibb.co/2gnrgJq maybe we'll get a few flurries yet
  10. Stormchaserchuck1
    Good job.

    Years of watching model setups and trends, as per current conditions. These days (for the last 8-10 months or so) model initialization is more important than you would think.
  12. Stormchaserchuck1
    All levels are pretty warm today. Upper levels are why it could snow at all, but I wouldn't be surprised to see mid-upper 30s temps.
  13. Stormchaserchuck1
    Hitting 61 at IAD today doesn't really bode well for the future of Dec 6 storm, besides maybe seeing a dusting on the grass. It could trend deeper, but temps are an issue this far south.
  14. Stormchaserchuck1
    Yeah, the western-central subsurface warm pool of +5c (warmest of the event so far) is increasing again, as of yesterday.
  15. Stormchaserchuck1
    It may adjust so the later part of the storm is warm, while the earlier part is cooler, if it digs deeper. I don't like that Aleutian high popping when the trough is starting to dig across the region (hr144). I'm talking about during-for the storm.
  16. Stormchaserchuck1
    Still.. with 50/50 low, -NAO, and GOA low, it's close to the setup of a big storm. My main concern is warmer temps as the PNA is trying to go negative as the trough pushes through.
  17. Stormchaserchuck1
    2m temps are approaching +6c in DC. It might be hard to get accumulations south of 40N.
  18. Stormchaserchuck1
    That's not that far off what we have going for Dec 5-6.. northern Greenland ridging going into the Arctic circle.. check. main problem is that -PNA tries to take over the GOA/+pna trough too soon, It becomes an Aleutian island ridge when the trough is hitting the east coast. better chances earlier, it's weird that the earlier wave goes negative so far west.
  19. Stormchaserchuck1
    Seems like we have a -NAO with the 50/50 low being the stronger signal.. two >+120dm regions not related to the storm, so that's a strong signal. Also to note is that in -NAO we are drier than average at a 0.40-0.50 correlation, so it usually hits big or much less (STJ phasing).
  20. Stormchaserchuck1
    Do you have a composite of December snowstorms at BWI? or even Nov-Dec?
  21. Stormchaserchuck1
    That's a really nice 50/50 low setting up on the 12z Euro before the Dec 5-6 wave. GOA low too, Not far from being a big storm.. temps here do seem to be somewhat marginal though.
  22. Stormchaserchuck1
    This hits the STJ A little late to the phase, but it's nice to see it drop down to 958mb pretty quickly
  23. Stormchaserchuck1
    12z Euro has 1" of snow here Dec 5th. I was talking about the time period earlier as a good +pna/-nao opportunity, it looks like the wavelengths in today's runs are more to match the upper latitude pattern.
  24. Stormchaserchuck1
    This is what I think is interesting.. we have a slight window around Dec 4-5 for cold, and we pop a SE ridge https://ibb.co/KyLRXY8 Not all the time everything is correlated, but we saw the same thing last March.
  25. Stormchaserchuck1
    Shoutout to the LR GFS that doesn't show snowstorms anymore if we aren't going to get snow. I've been noticing this for years.. in the early 2000s they always had a snowstorm.
