  1. GFS getting close now in FI to where I had expected the evolution to take us. There have been hints for days now but no model has really run with it thus far.
  2. That cold to the E is inching closer and closer each run too. I mentioned that after the 0z this morning.
  3. Means little at that range but GFS deep FI could be special…Arctic HP meets heights to the S with huge swathe of brutal uppers to the E.
  4. Cold longevity looks to be increasing to me. Forget short term slushy snowfalls, I’m more interested in the bigger picture.
  5. ICON going with an extension of cold…pretty locked in from this point-
  6. Looking good at 210, might not make it this run but a big nod to the EC E’ly here- You want to look for HP being advected N through, or just to the west of, the UK ahead of a sharp trough. Almost there…
  7. It’s not poor. The 18z has actually taken a step towards extending the cold. Look at the pressure patterns- 12z- 18z- Look at the polar heights and the ‘arc back’ of heights ahead of the N Atlantic LP on the 18z
  8. Thursday night looks prime thickness wise for convective streamers to pile in from the ENE. Wouldn’t rule out a more organised trough feature pushing SW in this flow, though uppers will obviously moderate somewhat around the trough if it happens (marginal).
  9. An E’ly around D10 has been hinted at for a couple of days now, even on the GFS…though you had to read between the lines. It has repeatedly shown a cold HP ahead of the reinvigorated Atlantic troughing.
  10. GFS 0z wants us to get the BBQs out after the cold spell I think the question is now, how much of the blocking will we lose before the background signals turn in our favour after mid month?
  11. The Euro trough is such a great feature of an El Nino winter to have.
  12. Love to see this- after a couple of days lull the next bout of amplification shows its hand upstream CW in full effect higher up-
  13. Put it this way, I can’t remember too many starts to winter featuring a two pronged assault on the vortex (and it is a full blown assault). You’d have to think there may be a memorable spell of winter weather on the way within the next 4-6 weeks.
  14. Looks more assured than 2022 at this point to me. It’s not just Greenland based, the jet is completely buckled to buggary with the HP in situ further E.
  15. The typical zonal flow looks absolutely snookered to me by 216 hrs on the GFS 0z
  16. No one mentioned Dec 2010? Wasn’t it just 0.1C away from being the coldest December ever recorded?
  17. I’m more struck by the extent of that Eurasian snowcover and the TPV sat starkly atop that blocking. Surely has to be strat ramifications from that going forward.
  18. Sustained cold spell on the 18z GFS. In the freezer pretty much as uppers at this time of year (for the next 7 weeks or so) will go colder and colder with minimal solar input.
