  1. GEM and ECM det runs are decent right out at days 9-10. A big worry is the poor UKMO run (at day 7). Still, a lot to be resolved. Hoping for a great eps set this morning.
  2. Indeed. UKMO day 6 close to a good chart. Close but no cigar I reckon.
  3. Yes, it's decent. Just need to watch the heights to the south (don't shoot me!)
  4. Interesting but way too far out to take seriously. The medium-term broadscale pattern from the ensemble suites suggests an atlanctic ridge days 10-12. Let's see how that evolves.
  5. Merry Xmas all. The UKMO is the most interesting evolution in the medium term. Less influence of the AH and seemingly more trough disruption. ECMWF det not interested in this type of evolution. One to watch...
  6. Outer reaches of the GEFS but this is where we want NWP to follow:
  7. No point trying to sugar coat the NWP - it’s poor. We really are dependent on medium range drivers - SSW, MJO etc. to deliver the wintry goods. The big elephant in the room is AGW.
  8. Nothing in the more reliable NWP to get excited about. December 2023 is likely to outturn a milder than average month after starting so cold.
  9. Yes, the ECM det is poor - let’s see where it sits within its ensemble suite. This is going to be a slow burner I feel.
  10. Interesting weeks 5 and 6 on today’s ECMWF sub seasonal. Let’s see if this the start of a trend.
  11. Yes as ever, the Azores High is a significant player during our winters. Let’s hope is stays well away. A new worry is rainfall totals - could be some big totals piling up as the lows meet that huge High to the east. Mild, very wet and windy in the medium term but then who knows?
  12. It depends. Uppers of +3 can give freezing temperatures via an inversion and uppers of -12, especially in early Spring may not result in sub-zero temperatures at the surface.
  13. Slightly disappointing output this morning. There is no deep freeze imminent (was this even ever on the cards?). Chilly for sure but any snow is likely to be over high ground. NWP also suggests weakening heights over Greenland and more mobility in the outer reaches.
  14. Unlikely - uppers too high and too much mixing of the air. Cold rain and 5C
  15. It’s gone tits up because someone broke ranks! Own up whoever it is…
  16. The lows to the southwest are troublesome - whether they make progress inland is up for grabs - high risk, high reward. Snow chances are there but also a chance that the cold air could be mixed out.
  17. The UKMO-GM is a very good model. It is consistently better (if the verification stats are to be believed) than the GFS. It is the first model I check.
