    Widespread very cold air by Monday afternoon.
  2. radiohead
    It's coming but slower on the 06Z. There are -6 uppers on the east coast at noon Sunday where there was -14 uppers on the previous run.
  3. radiohead
    Early days on the 06Z, but looks like the cold may be moving westward a little slower.
  4. radiohead
    Potentially. The coldest upper air in the south may end up being a degree or two less cold than 1991 but the overall area of very cold air looks like it will be larger than 1991. It's far too early to predict snowfall amounts though.

    1991 versus 2018(?)
  6. radiohead
    -13 uppers on a 50 member ensemble mean at 168 hours points to a high level of confidence that this is really going to happen.

    Oh my god!!

    Did anyone spot the channel low at 192 on the ECM?
  9. radiohead
    At way out at 177 hours, on the southeast coast, the warmest GEFS 850mb temperature is -11.3. All other 19 members plus the op and control are colder than that, most significantly colder. Absolutely bonkers.
  10. radiohead
    Windchill as low as -18
  11. radiohead
    You have to go back to 1991 to find comparable cold to that which is shown on the 18Z. There has never been something like this in the Internet era or era of modern computer models. The 18Z GFS gets to within about 1 degree of that event. 1991: 18Z GFS

    Incredible! -16 reaching Wales.
  13. radiohead
    -16 now reaching the coast... And pushing in! Coldest run yet from the GFS.
  14. radiohead
    Absolutely perfect.
  15. radiohead
    Regards timing, we will likely see a merging of the GFS and ECM options.

    My goodness, look to our north. I would love to see a 264 chart...
  17. radiohead
    Excellent 216.
  18. radiohead
    ECM moving in the right direction now, though still slower than the GFS. Would like to see one more adjustment further north but I'm certainly not going to complain about this.
  19. radiohead
    12Z ECM & 12Z GFS looking quite similar at T96
  20. radiohead
    Listed on Meteociel via the Tableaux GEFS.
  21. radiohead
    -18.8 on the southeast coast. 8/20 members get down to -16 or below.
  22. radiohead
    It really is incredible to see a GEFS mean chart like this at T180
  23. radiohead
    GFS hi-res ends with probably the biggest snow event/blizzard for Ireland in a generation. Purely fantasy island stuff of course.
  24. radiohead
    What a chart. Could be a major snowstorm or a snow to rain event, especially in the south.
  25. radiohead
    Windchill.....
