  1. They'll be available for the 27.00z models. I think they are more in support of atmospheric river research, because if they were truly about improving modeling for the East Coast storm they'd be seeding the sondes farther north.
  2. Would seem the 18z EPS is a little farther SW compared to the 12z, but this is effectively just a 6 hour slowing of the system. Mean QPF is similar, unless you live on the Maine coast.
  3. Ekster just pointed me to the Euro density functions and man there is a good wind signal showing up. The 10th percentile wind gust at PWM is like 17. 17 m/s! That's a helluva floor.
  4. We don't really have that many QPF sources to use beyond 60 hours. You have your standard GFS, GEM, and Euro runs, plus WPC's QPF (usually their super-ensemble blend) and the NBM. This would appear closer to the WPC blend, so at least it's using some ensemble data and not just deterministic runs.
  5. I'll never forget in the run up to Feb 2013 the NAM spitting out 4" QPF for PWM. Of course that in and of itself was enough to tease a historic event incoming despite it being a fantasyland forecast.
  6. If you look closely you can see the second shooter on the grassy knoll.
  7. Come on. We're one good melt from you away from a February 2015.
  8. At work now, but looking at PWSs online and my neighborhood went from 22 to 35 in like 15 minutes. Security cam may have fogged up when the temp spiked too.
  9. 14 degree temp difference between my house (22) and Martin's Point (36) 2.5 miles away.
  10. Downsloping off the massif. Seriously. Could be subtle warming from the downsloping that's enough to flip the ptype.
  11. Nickel size hail south of Toms Rivers.
  12. Honestly wouldn't be crazy. There is a ton of 0-3km shear, the question is whether we can drag enough instability inland. There is very little CAPE, including 0-3km CAPE, at the moment. I not sure the environment is going to improve all that much for Long Island and southeast New England enough to really be trouble in the end.
  13. It probably will be, but man it's close. It's a shit sandwich, but a lot of the forecast soundings are just on the verge of being supportive of snow at PWM when the bulk of the precip comes through. Maybe we get lucky a rip 2 or 3 inches in one hour before the flip.
  14. I'm just glad our changeover is happening in daylight, because then we may have some hope of verifying warnings before it gets rained on.
  15. I’m not aware of any systematic bias with shortwaves lately. I do know in the past models struggled with short wavelength spacing between shortwaves and would keep them too strong. However that normally affected the lead wave more, dampening it out, vs the trailing wave.
  16. Really amazing how the 18z NAM gives the double freedom tickets to Indiana. It manages to snow at LOT and TOL and somehow nowhere in the state in between.
  17. That’s how I’m reading it too. The northern stream is really dominant in these ensemble runs. It digs so much that the southern stream has no choice but to slingshot inland. I really don’t hate thinking of some of these “bad” runs as a WAA thump and done. Throw a laterally translating band across for 6” region wide and then slot. It wouldn’t be the worst thing to happen this winter.
  18. The 00z ensembles were really sensitive to the northern stream this time around. So that was what was really bullying the low pressure locations overnight. So some combination of weaker northern stream or stronger southern stream would be helpful.
  19. Yeah, maybe the morning run went to his head? Very clear westward shift from 12z.
  20. Looking at the 12z GEPS sensitivity it didn't really have a coherent pattern to follow until like 36-48 hours from now. It seems to be more northern stream dominant, like way up in northern Alaska right now northern.
