    We have ticked down a bit further to 15.6. Assume any temp rise for those to the east should stop soon.
  2. hstorm
    16 here in Great Falls. Temp has actually dropped ~2 degrees here in the past hour.

    Just measured 7.5” actual depth on the ground. Likely means 8-8.5” in total accumulation.
  4. hstorm
    Just measured 6” on the ground in Great Falls. Likely some compaction already from the sleet, so probably somewhere closer to 6.5” so far. Sleet is pouring down.

    One thing that the HRRR captured well on yesterday’s runs was the slowing/wavering of the sleet line towards far Northern VA. That certainly happened here this morning. HRRR was too slow on timing (NAM was closer) but good on this aspect.

    Wow. Dumping snow now.
  7. hstorm
    Still mostly snow in Great Falls. Hard to call this a bust … we are certainly getting the rates we need with the pre-flip snow.

    Pouring snow here in Great Falls. Changeover might be soon but we are certainly maximizing every minute of snow.
  9. hstorm
    Yep. Was about to write the same thing.

    At least for the DC suburbs, 6z RGEM looks slightly colder and slightly snowier than 0z. 8.2/-5.8

    Ukie did its weird p-type thing again on this run (panels of snow after the flip). Not as extreme as at 12z. But still there. So not sure how much to trust either the 12z or 18z snow map.

    Although heavy freezing rain is likely preferable to lighter freezing rain because it won't accrete as efficiently on trees, power lines, etc.

    Seems consistent with prior runs and other guidance:

    12k NAM:

    GFS:

    I noticed that too. Sleet/mix line stalls and then creeps south, presumably with the coastal transfer. Too late for anything meaningful for the DC metro but close. Also, like the NAM, would only take a small south shift in the stall point to cause a meaningful change for the metros. But a solid run regardless.

    Ukie looks colder than 18z through 60 (which was end of run for the 18z).
  18. hstorm
    That's how we roll in America. Canadians and Ukies and Euros just can't grasp it.
  19. hstorm
    RGEM did the same thing at 12z.
  20. hstorm
    ICON and RGEM both seem pretty similar to their 12z runs, at least as to final outcomes.
  21. hstorm
    3k NAM looks quite a bit colder at 60 (end of run) than the 12k.
  22. hstorm
    I have always assumed it counts sleet because sleet counts as snow (for reporting purposes)
  23. hstorm
    6.47 miles, give or take a few feet. More seriously, I always take "N&W" to mean changes start at the fall line, with snow amounts, ratios, whatever getting better as you go further N&W from there.
  24. hstorm
    Hopefully this should help quell some of the inexplicable moping about likely snow vs. mix amounts. Also, the trends in the past 12 hours have largely been stable -- a little colder, a little warmer, some small changes to total QPF. I didn't stay at a Holiday Inn Express last night but I just don't see anything right now that would suggest further dramatic changes.
  25. hstorm
    Largely similar to 0z. Certainly not bad.
