    George is in Foxborough

    Chris (Oceanstatewx) and I were discussing yesterday that this one will likely have a stripe of 12-15" somewhere because as the bent back mid-level WF progresses north, it encounters so much resistance that it starts sliding east and where that happens is where a zone sees quasi-stationary banding for 4-6 hours and that will be enough to turn the usual 6-10" into a 10-15" jackpot zone.

    May have to bump this one Friday evening....
  5. ORH_wxman
    There's also a nice ~600mb sig that is up into upstate NY over to central/northern VT and into Phin/Alex land....I bet there will be a band up there too that isn't really visible on the QPF maps.
  6. ORH_wxman
    Yes....I expect a little nudge back north too.....I'd be surprised if the storm verified as cold as the 12z Euro....but it's good to see a south tick to give some wiggle room for when that north nudge happens.
  7. ORH_wxman
    Anything meaningful should be done by mid to late afternoon Friday there....might be some lingering light snows into evening but the meat of the event is over after 18z.
  8. ORH_wxman
    Lot of confluence up north....difficult to trend it hard north when you have a 1040 high sitting over Ottawa the night before. It's not like one of those SWFE's where the high is trying to hold on in Nova Scotia as the storm gets going.
  9. ORH_wxman
    That run annihilates the pike region.
  10. ORH_wxman
    Euro looks south of 06z so far.
  11. ORH_wxman
    First flakes are prob sometime after midnight on Thursday night.
  12. ORH_wxman
    Ukie is the first model to go north this cycle aside from the NAM....though not a surprise since the Ukie was obscenely cold at 00z. Looks pretty close to the rest of the non-NAM 12z models now.
  13. ORH_wxman
    The fact that all other 12z guidance is actually trending in the opposite of direction of the NAM makes it even less likely to believe the NAM than normal. I personally think the GFS is prob too cold, but the NAM is prob too warm. I'd expect them to converge.
  14. ORH_wxman
    All of those mesos are colder than the NAM....the NSSL one is too and so is the FV3....though I am tossing the FV3 until they figure it out. It's been too cold this winter....its even a lot colder than NSSL and ARW mesos.
  15. ORH_wxman
    Reggie went south too.
  16. ORH_wxman
    There will definitely be way less QPF if the vort is tracking into the St. Lawrence valley up north or northeast of Ontario. The Euro shifted north at 06z too....it's not like the 12z NAM but it tracked it over like southern Lake Ontario up toward Tug hill instead of BUF to ALB like the 00z run did.
  17. ORH_wxman
    I don't think you can toss it...other guidance may continue to shift north with the vort track too....but there's no reason to hug the NAM either.
  18. ORH_wxman
    I expect some northward ticks (I've been saying it for days actually)....but there's a difference in mere northward ticks and the 12z NAM. The question is does the NAM start coming back to other guidance...which I think it probably does. But maybe it scores a synoptic coup too.
  19. ORH_wxman
    NAM is still synoptically very different from other guidance...it is tracking that vortmax NORTH of Lake Ontario....nevermind over it. If it is wrong with that, then it's going to bust too warm. It's not "Sniffing out a warm layer" like we sometimes see in these events when they all agree on the synoptics. The NAM is literally about 75-100 miles north of other guidance on the vort track and that makes a huge difference.
  20. ORH_wxman
    Warm layer there is kind of weak sauce...and lower than the typical 750-800 zone you'd normally see it. Something to watch if we're not going to see that really distinct warm layer in the 750 zone.
  21. ORH_wxman
    It would have been almost impossible for it not to be...it was so cold at 06z.
  22. ORH_wxman
    It was frigid at 06z. I’d be surprised if 12z came in as cold but it’s probably a red flag not to believe the NAM if it does.
  23. ORH_wxman
    It's like 2-4" down there now.
  24. ORH_wxman
    You can get like 5 to 1 sleet ratios if it’s really cold with a ton of pixie dust mixed in but that type of ratio usually doesn’t happen over a long period of sleet. Best to assume 2 to 1 or maybe 3 to 1 in a colder profile.
  25. ORH_wxman
    3-4” of sleet from half of round 1 QPF? That would be like 6 or 7 to 1 ratios just on sleet.
