    Euro is showing a pronounced warm layer from 850-700 close to the cities in the key 93-96 hr window that the GFS doesn't have. 925 layer is definitely better and 850 is marginally better closer to the cities than the 12z run.

    its a good run compared to 18z (has DCA at 32)

    12 z EPS has 31, 69 for 4,1 inch chances for DC 6 z EPS had 35, 65 for 4,1 inch chances for DC 12 z EPS has 92, 55 for 4,1 inch chances for Germantown 6z EPS had 78, 49 for 4,1 inch changes for Germantown

    The storm is still 4 days and ~16 model cycles until onset. The final solution isn’t going to be exactly like any of the 12z runs today (for better or worse) so no reason to punt this yet

    Worth staying up for the Euro (and having an earthquake) but it reminds me a bit of the 12/16/20 storm where 4-5 days out we looked good for significant snow but the mix line quickly punched into the immediate metro. It was still a pretty fun storm with some high initial rates.

    @psuhoffmanand a few others honed in on this window around Christmas

    We need the Low a further south than St. Mary's County for snow in immediate DMV but we could at least all get on the board w this track

    18z GFS is better for immediate metro
  9. rjvanals
    Yeah I could see this being like the mid Jan 2022 storm as the cold air is a bit stronger out front on the euro vs it’s 0z run

    It’s a week out and w the 1/4 system not yet resolved we have room/time for significant changes

    Euro misses south it looks like; has a major difference w GFS w what happens w the 1/4 storm in the Canadian maritimes
  12. rjvanals
    GFS is interesting for the 1/7 storm
  13. rjvanals
    We got blue on the GFS for the 1/7 storm

    It close enough to watch. This run we get fringed w light precip but it’s cold enough at the 925 level we’d snow if the precip was heavier

    12/11: 1.6”

    Similar scenes to mine. Went 1.4 conservatively but it was likely closer to 2 here.
  17. rjvanals
    1.4in here w snow starting to wind down

    Looking at some of the road cams in the band the ICC is snow covered as you get closer to 270
  19. rjvanals
    Yeah the band is legit w snow sticking to the driveway and slush buildup on the street
  20. rjvanals
    Light snow in Potomac, 34f w enough accumulation to make a slush ball off the cars hood
  21. rjvanals
    Snow mixing in; 35f

    12 z NAM looks to speed up a changeover but gets the precip out much quicker than earlier runs
  23. rjvanals
    Euro looks somewhat sleety in the metros w a change to snow looking at soundings.
  24. rjvanals
    Big red flag for me is there’s no real arctic air behind the system. When it’s supposed to have flipped over in the metro it’s 34f in Pittsburgh. That’s not gonna do it imo

    No 87 was the big Veterans Day storm. The one in 95 was short duration but had intense rates and enough sleet for my 10 year old self to sled down the driveway.
