    Just based off Will’s maps, looks like more snow before a flip than 0z, but more precip total after a flip? I again will sell on ZR vs sleet…

    I’m mostly curious what info the normies are getting. Family friend that visited last night was lamenting the rapid Apple weather app snow total changes…

    WBAL slightly increasing? Low end now 6”, same likely range, high end now “15+”
  4. WxUSAF
    I’ll wait until Saturday morning or so and NAM 3k is in range, but I’m really skeptical of ZR north of like EZF (and maybe even south of that). Really would think snow to sleet to storm over.
  5. WxUSAF
    To use CWG’s terms, there’s definitely a boom scenario with high ratios and stronger WAA thump than modeled. Bust scenario is faster sleet mixing. Combine both options and I’m back to 8-14”.

    Needed a break by about 7pm yesterday. Think I was mostly scrolling this forum for like 13-14 hours Thankfully things didn’t go to shit overnight. 8-14” still looks like a solid range for most of us in the metro area at this stage.

    More separation on 18z vs 12 euro. Icon gets tossed. Blend the whole euro suite until we get within like 36hrs and get 3k NAM profiles.

    Looks pretty similar to 12z I think. I’d guess that again most of the precip is over when mix starts. As @psuhoffmanwas saying earlier, they’re linked. Heavier precip helps keep the column cold.

    Also seems reasonable for now

    Note Tomer’s EPS predominant precip plots are all snow for the metro areas.

    @mappy Tom T just said “low end” 5”, “high end” 15”, “most likely” 8-12”. Seems solid to me.

    So far it seems all the divergence in 18z model outcomes is based on the northern stream shortwave, not the Baja low. Maybe the recon has enough fuel to make it to northern Canada??
  14. WxUSAF
    GFS is clearly an outlier in one way, but still looks closer to the European consensus than the icon. Still really hard to bet against the Eps and the euro AI when they are in close agreement like this. Blend those two and let it ride.

    RGEM looks awful out west vs what we want and it still looks like it’s going to crush us before mix.
  16. WxUSAF
    And that’s what basically every other run has. Icon has a cleaner, single northern shortwave that perfectly phases. It’s quite beautiful actually if you ignore how it Fs us over lol.
  17. WxUSAF
    Icon basically has a perfect, full phase of the northern stream and the Baja low. It’s textbook. We’ve only seen that on like 1-2 runs of varsity models yet for this storm? Seems pretty unlikely with how much is going on. I’ll take 6” and taint as the fail scenario.

    Kudos to them. I noticed this morning Alena Lee said they weren’t going to give totals yet. But have been saying big snow possible.
  20. WxUSAF
    It will virga for awhile, lower atmosphere will be super dry. So expect the “donut hole” look on radar. But we won’t “miss” any precipitation because of that. Models account for that. Once the column saturates, it will probably go from light flurries to steady snow quickly.
  21. WxUSAF
    Yeah, any weaker/more easterly northern wave helps reduce chances of a GGEM scenario.
  22. WxUSAF
    Look at where that big northern shortwave enters the country around 78hrs. Much farther east than 12z. Continuing to 84hrs, part of the difference is speed, but it’s still east. I like that. Would like to see that same thing on the varsity models.
  23. WxUSAF
    I’ve used up all my reactions for today! I expect this to probably continue through Monday?
  24. WxUSAF
    A foot before mixing! I will caveat that with the farther NW track, we don’t get those absurdly deep DGZs like we were looking at a day or two ago. I’d expect more like 10-12:1 in the WAA thump in total.
  25. WxUSAF
    How are there 2 more workdays before this shit starts?? I’m already talking to you jabronis too much.
