  1. could tell it was going to be more amped around here. PNA is better and heights are lower farther SW
  2. euro and CMC keep the main TPV lobe farther west, GFS and ICON have it leaking east which suppresses heights downstream
  3. if that vort moves hundreds of miles SW you have a MECS on your hands. not even exaggerating (not like that's going to happen)
  4. with the GFS and CMC looking more amped and the ECMWF and AIFS largely holding serve, I think we're trending towards the first plowable snowfall of the year for the metro. let's give it a couple more days, but things are looking good
  5. if you get the TPV that amped, you can def get 6" of snowfall on 0.4" liquid. the fluff factor is usually strong with these systems
  6. CMC making the same shifts as the GFS. TPV is more favorably oriented
  7. yeah, GFS made a shift towards the ECMWF with a more favorable TPV orientation
  8. if you're talking about pure VP, there is literally almost always a standing wave there. like for decades
  9. not surprising that we're seeing a warmer interlude with some -VP contaminating things in the IO and western MC. this quickly changes back to strong WHEM forcing in late Dec, likely signaling a flip back to a more favorable pattern after Christmas and into the New Year
  10. lol are we really just tossing the most skilled guidance right now in favor of the GFS and CMC? if the euro showed rain and the GFS showed snow i'm sure that wouldn't happen
  11. this is literally all it takes. slightly more lean westward with the TPV lobe -> higher downstream heights -> more buckling
  12. this is literally all it takes. slightly more lean westward with the TPV lobe -> higher downstream heights -> more buckling
  13. same general premise as 1/6/22 if you recall. that was a nice little Arctic wave
  14. this is why it’s sometimes not as simple as worse PNA -> weaker storm… the TPV is better oriented and allows the vort to curl more on the ECMWF
  15. this is why it’s sometimes not as simple as worse PNA -> weaker storm… the TPV is better oriented and allows the vort to curl more
  16. the GEFS is so horribly underdispersive that the OP probably is influencing its ensemble 16 days later
  17. AIFS ENS actually looks pretty nice. I feel like this is more likely given the tropical forcing but who knows
  18. isn’t most of the warmth forecasting on this forum persistence forecasting? lmao
  19. ECMWF with a pretty significant improvement with heights out west. went from nothing to something
