    I expected worse there

    Even near 32° it’s essentially done without the dp drain. The driveway is a skating rink and the birches are nearing the ground, there’s not much radial ice. Wintry scene though.

    Beer? There’s a few people maybe at 1500’ with a little more accretion, but most are sitting at the 32° ice water bath.

    00z HRRR had 29° at MHT at 7am.
  5. dendrite
    Meh

    Definitely some sag to the pines and birches, but it’s a run of the mill icing event. I’m actually surprised how early the accretion shut off even way up into NNE. We’re still in a drought so hopefully it keeps pouring.

    This is going to end up being a major nothingburger. WTTTE
  8. dendrite
    Already 32°

    29.5° Driveway is icy, but a lot of standing water too.
  10. dendrite
    29.3° -ZR

    We still usually run moist lapse rates under the inversion. The 1k hills are almost always colder in icing setups.
  12. dendrite
    I think you will get some decent icing. 1k way up there will give you an advantage over most of the population in NH. I could see you pulling 1/3” radial.
  13. dendrite
    It’s a 3hr burst of +ZR which will limit accretion. After 12z everyone starts rotting AOA 32°. I don’t care what a weenie algorithm of “fzra qpf” shows.

    Overblown. Cope.
  15. dendrite
    We deal with the overblown icing products every icing event. There will probably be spotty outages in the hill towns and here-north, but I’d be surprised at anything widespread. A half inch of accretion is a lot of ice. Heck this is only 5/16” radial.
  16. dendrite
    A lot of beer
  17. dendrite
    lol…that’s like 70% of the euro qpf in the Merrimack Valley. We’re not getting a half inch of accretion
  18. dendrite
    They bit on the HREF icing. I’m still taking the under.

    The joke is on you. This is what he sees when he posts.

    “Canadian model leading the way” GL with that

    Even 32° here with full sun. Nice afternoon.
  23. dendrite
    But it only takes 15 minutes of freezing drizzle to turn I93 into a demolition derby. At least the state piled a couple hundred thousand pounds of salt on the highway for the 1” the other day so the salt residue remains.
  24. dendrite
    And to Tip’s point…. A short period of +RA with marginal <32° temps and no evaporative cooling offset isn’t going to result in significant accretion. A lot of that liquid will run off and “waste” to the ground.
  25. dendrite
    Gotta separate QPF as ZR and actual accretion too. I think you’ll have some decent icing up there around 1k Gene. But there’s really no ageostrophic lower dewpoint drain to offset the diabatic warming so once the ZR begins it’s a slow trend upward to 32°. I think we’ll probably wedge into the 30s until the cold fropa, but I think any additional accretion ends here in the morning and maybe mid to late morning up there.
