  1. You definitely tossed the NAM this storm after pimping it for the last 2 days.
  2. 19z HRRR is going colder than 18z too...not an easy forecast down there.
  3. The mesos look like they try and temporarily stall the sleet line just south of the pike or near the RI/MA border for a couple hours near 14z-15z. If that happens, that's how we'd pick up the 8-12" amounts I think...versus more like 6-8".
  4. Here's 15z tomorrow....when you see those wind flags going from 60 knots (even 70 shows up there) out of the SSW and turning to 20 knots out of the SE like that over BOS....that's what we mean by a "bent back WF" in the midlevels. You usually want to see that to get 1-2" per hour on the front end thumps.
  5. 18z tickled a little colder...starting to narrow the goal posts a bit more.
  6. 18z HRRR coming in a tick colder through 12h. Would help out the S CT peeps.
  7. Yeah I could see the Euro solution verifying with just one more tick north....Euro still has warning snows from HFD to PVD and my guess is that nudges just a bit more north.
  8. Yeah....that thump is really good here. Most of our snow is from 4am to 10am....so it's important that it slams during that time before we dryslot.
  9. Yes, I think this is actually a pretty good map. I might bring the "uncertain" dotted line up into the BOS-ORH zone too, but that's nitpicking
  10. Well you chose the 24h sounding....at 12z tomorrow. Most guidance has you pinging by then so the GFS is cold. Here's the 3km NAM sounding at 2am for you....notice how its marginal and perhaps could be sleet: Now here's the sounding 2 hour later at 4am....notice how it has cooled a bit as the lift in the DGZ looks much stronger and the precip gets heavier
  11. You guys in SW CT might start as straight sleet but then flip to moderate/heavy snow for a few hours as the lift deepens and cools the marginal warm layer, before it finally gets overwhelmed by WAA.
  12. No it won't mix that much there....it might ping as the precip starts getting lighter near midday, but the damage is done by then....decent chance you don't mix at all.
  13. Looked awesome for pike up to S NH....I'm expecting to ping though even though GFS says it stays south. But just need to hold off the pingers until about 15z and we're locked for solid warning snows.
  14. Yeah the ensmebles have a bit of reload....so for a few days, the cold in Canada looks a bit drained and gives the impression that winter threats are over. But once the reload happens....you can see how Canada cold reloads too....see animation below on the T850 anomalies....I started the loop at 192 hours when Canada is kind of drained of big cold and watch how it reloads:
  15. FV3 is garbage....useless in this setup until they fix its bad cold bias.
  16. Almost dead nuts with 06z. Might have been like 4 miles north, lol
  17. Yeah, I've been saying that zone for days? Lol....not sure why you are making it sound like I was previously disagreeing with you.
  18. They will occur where the QS banding starts slowing down and sliding east....wherever that occurs is where the 12"+ amounts happens. Best guess is S VT to S NH...but it could be into N MA too.
  19. It is still tracking the vort north of the Euro and some other guidance....the 12z run is tracking it over northern Lake Ontario. While others are more like BUF to ROC . It's not a massive difference but that 25-30 miles matters when we're talking about areas that are flirting with the sleet line.
  20. We didn't get more snow along the pike than 06z because the QPF was pretty weak sauce this run compared to previous. QPF is under an inch for us through 21z tomorrow on the 12z run.
  21. Def colder than 06z though...06z gave almost no snow south of HFD, now the 12z gives advisory snows down there.
  22. 12z NAM tickling colder through 21 hours. Heavy snow down in parts of S CT at 09z while the previous run was scalping them.
  23. Yeah the CF will def be most pronounced in SE NH or S ME....but that isn't the only factor in the best snowfall...you want to overlap that with the strongest fronto banding....the fronto banding is a little stronger south and it weakens some as it goes north into S ME. So I'm picking your area to S NH to get the best of both worlds (longest exposure to good fronto banding while getting CF enhancement at the same time)
