  1. Euro looks worse than 06z....it really is a shame because it's a very solid shortwave diving SE toward the lower mid-atlantic, but there's just no ability to lift the heights downstream with the southern stream turd messing up the spacing. Without that, you're prob looking at a fairly healthy Miller B.
  2. Every piece of guidance sans GFS is significantly better than 00z. Still needs more work though on most of these solutions. We haven’t been able to get a consistently positive trend for multiple cycles in a row though which is what this system needs. The euro also needs to come in better I think for me to really entertain this being still in play on the 00z guidance. When I say “in play”, I mean for something that’s at least 4”+….a C-2” deal isn’t what I’m discussing.
  3. It's the NAM, but interesting trend on the 12z run....everything further west with the main shortwave and that includes the TPV up north. If other guidance follows suit, that would help bring this thing much closer/further west.
  4. Most of the ensembles are prob whiffs, but there is definitely a subset that are likely significant hits...you can see the spread still
  5. EPS increased the mean QPF a decent amount so there must be some decent members in there. We really need another positive step at 12z today if we’re trying for something other than light accumulations.
  6. It’s garbage. Maybe you get lucky and get more than an inch of slushy paste but that event is complete trash except for a narrow stripe in NNE and maybe adjacent CNE.
  7. Correct. You can’t amplify a shortwave diving down when there’s a southern stream vort ahead of it keeping the downstream heights lower…it prevents the essential downstream ridging to occur in front of out main shortwave that is needed to create a coastal in this setup. So we either need to it speed up and get out of the way (ICON sort of showed this) or slow down enough to get captured by the northern stream. Otherwise you just get destructive interference.
  8. GFS southern stream is a big problem that you didn’t see on the icon run. Note around hour 102 on that southern stream vort. It’s still onshore on the GFS and it’s way offshore on the icon.
  9. Just caught up on 12z stuff. Not the trend I wanted to see, but it wasn’t fatal IMHO. Kind of more status quo. Still decent spread looking at ensemble guidance. There’s a solid chance of a modest event. The PNA ridge is so damned tall that I don’t mind a little optimism still…as in I don’t think it’s completely unfounded. But I do think you need to see some better trends going forward. Status quo won’t really cut it if we’re aiming for more than a small event.
  10. As we get inside 6 days, the changes will matter more. They are more likely to be correct and not just stochastic variance so that’s why we want to see the deeper solutions returning pretty quick during the next couple of cycles. When we’re 180-200 hours out, the run to run changes mean very little. By the time we’re like 120-132 hours out, any significant moves are more likely to reflect reality.
  11. Yeah it’s absolutely embarrassing the state of our old obs archives. It’s literally a bunch of text and we have trouble getting it. Does this site have them? They have a bunch of stuff but not sure if they have hourly METARs…maybe someone with more patience and time that’s I have today can search it https://mesonet.agron.iastate.edu/wx/afos/list.phtml I used to grab old AFDs from here
  12. It trended the wrong way though which is concerning. Want to see more amplification on todays runs or the ceiling on this threat will be quite a bit lower. I’ll still take any snow, but the higher end potential is gone if you aren’t digging that shortwave down into the southern midatlantic.
  13. 06z euro looks more like GFS. Clipper type system but you’re pretty close to redeveloping that for something bigger. We need to trend this back toward digging the initial shortwave deeper and that’s how you get a higher end system
  14. Classic….KNZW Infamous for the heavy snow from OES and sleet from synoptic precip in one of the Jan ‘94 storms.
  15. Ensembles continue to show a pretty significant warmup between Xmas and New Years. Weeklies continue to show a rapid reload to a much colder pattern in January lasting most of the month. I’ll believe it when I see it but I do believe the reload part is real. You can see the very beginning of it at the end of the regular EPS run.
  16. Yeah agreed. The more amplified solutions are all bombing this thing out into the 980s (and even 970s on the next frame…a couple of them due east of BOS.) I think this definitely speaks to the “higher end potential” was I just talking about to Mark. If this amplifies enough to hit us, it’s likely to be a pretty strong system. Hopefully not too strong and too far west…lol.
  17. EPS has been speeding up the second wave a bit more because it’s weaker on the first wave than a lot of other guidance. Esp the GFS suite which is slower. But regardless of whether it’s the 21st or the 22nd, we’d rather have the second wave be the main player because it has a deeper cold airmass in place and also a more poleward PNA ridge so it has higher end potential from a pure cyclogensis standpoint. The ceiling on the first wave is a lot lower.
  18. Ukie looks decent at 144 too. Might want it slightly more amped but very nice look overall synoptically. Ukie always seems to either come in flatter or crazy amped in the medium range
  19. Definite positive trends at 12z. What I wanted to see. Amplifying the 21st-22nd wave behind the first one is the ideal solution because we have a legit antecedent airmass in place. None of this garbage-0C-at-925mb crap at the onset.
