    Yeah, 2 years in a row the extreme -PDO Fall was not a warm Winter pattern in the east. The only other comparable -PDO Fall in magnitude was 55-56 and that was a cold Dec-Jan in the east, too.

    6z GFS vs 12z NAM, same time

    Cold Winter showed its hand when the Arctic was freezing this Summer.. In August we went sub-5000dm, which was the coldest N. Hemisphere H5 on record for Aug. You know the eastern US starting cooling down around that time, too. I ran the analogs, and it fits a perfect warm-to-cold season progression since 2012.

    The maps we are posting is accumulated precip. There may be some virga Sat night but that's not counted.

    Was going to say the 84hr panel actually looks really good. The differences between the NAM and 12z GFS at 72hr in the Southwest are pretty extreme. Maybe the GFS starts phasing that sw energy sooner.
  6. Stormchaserchuck1
    Still a 1042mb High pressure in NY state on the NAM at 84hr. That's a tough wall for this low pressure to climb against.
  7. Stormchaserchuck1
    Almost a negative tilt over AZ on the NAM at 60hr lol
  8. Stormchaserchuck1
    I'm comparing to the 12z GFS. SW piece isn't cutoff on the NAM at hr57
  9. Stormchaserchuck1
    SW energy getting caught up by the northern stream way early on 18z NAM fwiw
  10. Stormchaserchuck1
    18z NAM at 51hrs has the northern stream further SW than the 12z GFS at 57 by a pretty good amount actually. And the sw near Baja is ejecting more quickly
  11. Stormchaserchuck1
    15z SREF looks more amped/north
  12. Stormchaserchuck1
    Pretty strong trend in the last 24 hours actually. Remember when 24 hours ago the GFS had no snow, was too far south? I think we still have some time to move this thing around a little. It's hard to believe the low pressure will cut much further with strong High pressure to the north though. This LP north is actually creating some stronger wind gradient in the snow zone.

    Wow I can't believe PHL mixes.
  14. Stormchaserchuck1
    1042mb High pressure in NY state when the precip starts is insane!
  15. Stormchaserchuck1
    NAM much more phased than the 6z GFS fwiw
  16. Stormchaserchuck1
    9z SREF
  17. Stormchaserchuck1
    They may eventually issue some blizzard warnings if that High pressure stays so strong to the north.
  18. Stormchaserchuck1
    If you like cold, you have to like this look. Deep mid-Winter cold pattern for the east coast
  19. Stormchaserchuck1
    SREF looks north

    ^I've done that exercise too many times over the years lol Here's the monthly PNA data: https://www.cpc.ncep.noaa.gov/products/precip/CWlink/pna/norm.pna.monthly.b5001.current.ascii.table 65-66 and 72-73 were the greatest anomalies.. -PNA.
  21. Stormchaserchuck1
    Very cool that it's correlating with a good pattern for the 2nd time this Winter
  22. Stormchaserchuck1
    In Strong ENSO events the PNA usually holds the same state through Dec-Jan-Feb and sometimes March though
  23. Stormchaserchuck1
    Yes, you pointed that out way early and it was correct. If I recall correctly, it was strong like, 10/10?
  24. Stormchaserchuck1
    9z SREF way north early fwiw
  25. Stormchaserchuck1
    It's important to know what ENSO does as a first point. There is a North Pacific High correlation (+NOI in La Nina)... when you get a strong +PNA pattern in January... that's not La Nina impacting. I do wonder why Larry got that like 10/10 of negative ENSO -PNA Dec's went +PNA in Jan since 1980. It's right, but that's not what La Nina does. I think it has something to do with the Kelvin wave associated with warmth spreading to the central-ENSO-subsurface.
