    RGEM is slightly north too, at least with the overall precip field. 12k NAM has 1”+ snow up to around Fredericksburg.
  2. hstorm
    6z NAM is way NW. 3k NAM is less aggressive but also significantly NW.
  3. hstorm
    ICON gives Richmond ~10 inches. It's not that far from a hit.

    The good news here is that a 400-mile north shift would still give us the 2.5" that Savannah gets on this run.

    IAD report seems low. We ended up with somewhere between 9.5 and 10 and we are typically pretty close to IAD on accumulations. Would be surprised if they had 2” less than us.

    As a Pats fan, game was almost as intense as the storm. 20” would be nice but I’ll take our 9+ inches of snow/sleet.

    We have ticked down a bit further to 15.6. Assume any temp rise for those to the east should stop soon.

    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.
  10. 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.
  13. 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.
  14. hstorm
    Pouring snow here in Great Falls. Changeover might be soon but we are certainly maximizing every minute of snow.
  15. 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.
  23. hstorm
    Ukie looks colder than 18z through 60 (which was end of run for the 18z).
  24. hstorm
    That's how we roll in America. Canadians and Ukies and Euros just can't grasp it.
  25. hstorm
    RGEM did the same thing at 12z.
