  1. I have a feeling the gfs will hold onto the big storm until tomorrow 12z or even later, then do the most spectacular cave we have ever seen. By that time, the damage will have been done.
  2. Thats a legit ULL, we’ve gotten something like this before when getting missed by the coastal itself
  3. Looks like we’ll have to wait until tomorrow 12z at least to get better consensus. Yet another can-kick. Unless you toss the gfs AND its ensembles, then maybe we’re getting closer to the right idea. Not sure I agree with the trough going neg tilt so fast given how the progressive flow has been.
  4. (not that I'm buying the GFS, just surprised that it doubled down and went west instead of shifting east like the other models)
  5. I don't know why it's verifying worse than other models. Maybe related to budget constraints, they're focusing on AI (as we can see with the new AI gfs and its ensembles, and the hybrid) instead of improving the operational model itself like ECMWF is doing with both.
  6. Yeah, the surface may not show it now, but if it keeps trending this way, it'll be closer to a boom scenario
  7. Exactly! You’re really getting it. This is why we need blocking to slow down the flow a bit, and La Nina winters are notorious for the northern stream to push the jet streaks too far out resulting in suppression or fish storms (and that NC blizzard). There are exceptions to this like Jan 1996 and 2000, and there’s a small chance that this one could be added to this list. That is, if this whole thing trends west and not the typical east leading up to game time.
  8. Great analysis! For jet streak placements, I look at 200-300 mb for that. it’s close to a classic double jet streak system where the SLP deepens under the left exit region of the jet streak off the carolinas overlapped with the right rear entrance region of the other jet streak off new england. same with cmc euro, though, isn’t quite a double jet streak - more like one long jet stream rounding the lw trough
  9. That the models shifted in our favor after that sampling and ingest is a good sign
  10. Wasn’t using wxbell, different algos I guess. Probably the big dogs got knocked off this ensemble set
  11. I said wait until 12z wed, and here we are. Looks like euro can kicked us to tomorrow or friday
  12. Will be interesting to see how the euro shifts for 12z today...
  13. Main takeaway so far is we're not out of this yet. I was hoping for higher confidence today, but looks like confidence will remain low until at least 0z Friday. Yes it sounds like I'm kicking the can, and maybe I am. But all these vorts flying around and a minor change can make a huge difference. This isn't a typical SS wave casually approaching from the SW in a linear manner.
  14. Since I’ve moved back, I’ve averaged 11” imby but that includes the dreadful 22-23 of a winter. So if I take that one out, my avg goes up to 14” over the last 3 winters. Pretty similar to the early 90s iirc, was kinda disappointing after the late 80s which was nuts. At least we’ve had colder stretches this winter and last than those years.
  15. Yeah, it doubled down. But remember it's not as dispersive as it should be at this range. The only reason we're giving it credibility is that its 500mb verification scores are excellent.
  16. I did notice that although the vort was stronger on the mean, it was broader and the tilt wasn't quite as negative (to my eyes). Starting to wonder if it's an increase in dispersiveness among the ensembles before they "reset" (converge) towards a likelier outcome (this typically happens at 4-6 day lead times, where AI ensembles have the opposite problem - under dispersiveness).
  17. EPS mean stronger vort than previous run. Too soon to tell for qpf, mslp, but I don’t think its a giant step back.
