  1. First 12z Ensemble means: EPS: GEFS: Canadian ENS: EPS members: EPS members (2): GEFS members: CMC members:
  2. Euro wasn't too far off IMO, suppressed, but not as bad as the GFS dropping a TPV over the outer banks. There have been some wild ensemble runs lately, I'll post once EPS members are in and we'll see what that looks like.
  3. Well, Euro is running on Weatherbell, let's see what the wheel of NWP spins out for us now.
  4. There's a frame with ocean effect snow in the middle Keys.
  5. Kind of a non sequitur from me this AM but we finally have the MJO as plotted on the RMMs moving out of 6: I don't really put a ton of stock in the RMMs alone, but from the perspective of model watching, I think they can kind of give us a plotted idea of the "numerical" part of Numerical weather prediction, i.e. models and where they're coming at the pattern from. I just found it interesting that whatever slew of variables it looks at had the value stuck in 6 for almost 10 days, despite model forecasts consistently trying to move it out and now it is finally chugging along.
  6. That reminds me, I found something up in Kingsport yesterday:
  7. Just looked at the 12z Euro and that looked nice.
  8. Definitely quite a spread with tropical Pac convection, but it does seem to be trying to glacially slide eastward. First thought when I saw this was Darwin looks less stormy than Tahiti and sure enough we have a rare (for this fall and early winter) negative SOI today. Pretty good drop over the past few days too, relative to recent trends:
  9. The only thing I can think to add is that the MJO RMM plots and whatever combo of factors that go into giving any individual day a place on the plot (OLR, wind anomalies, etc...) have been really stuck in low amp 6 for a few days now. I've not really posted much since I don't know what I can add at this time, but I have been watching the MJO and even though it's been slow it hasn't really gotten stuck over the past few weeks. It is now firmly stuck. Maybe those same "stalled" anomalies are competing with each other in how the OP GFS model resolves and propagates their influences them and causing some western trough tendencies? Feels kind of like I'm grasping at straws, but western troughs... ugh.
  10. Euro AIFS ensemble? https://arxiv.org/abs/2412.15832
  11. That was some '96 like weather at the end of the 12z GFS.
  12. Also, it is still "slikerin' owl snot" on my deck this AM.
  13. Some interesting radar obs this AM. Ft. Campbell snow band overnight: A streamer off of Lake Michigan kinda sorta held together to make it to N. TN east of Nashville this AM: ZOOMed in:
  14. Just walked out and same here, minus any flakes.
  15. Flurries up here in MoCo now and a howling N wind.
  16. I also don't like to to see BAMWX chest thumping on X. Bad sign. Totally unscientific to let that to worry me, but it is what it is.
  17. Yeah that trough hung up over the SW doth maketh me a bit nervesome. We're firmly in MJO 6 after having spent several weeks in 4/5 and I always feel like there is a lag in the pattern over North America. I think we've seen this so many times though we're a little "once bitten twice shy" any time that trough starts to set up in the southwest.
  18. MRX has modified their expectations:
  19. Finally got some really nice thunder here! Make of that what ye will for the pattern.
  20. HRRR has a pretty helicity swath over the current warned storm and paints another one over my head, later today! Joy
