Model discussion - hunt for cold Christmas period 2021
DavidS replied to Paul's topic in Forecast Model Discussion
Looking at the 12z ECM from D5 to D10, it looks the Azores ridge may want to pull back west somewhat. But that is about as exciting as it gets. (These may not be in the right order) -

It will no doubt verify -
Not sure the ECM is really bringing the cold, as the high isn’t around for long enough to build cold.

Yep, would do me too

I’m fairly sure 850hpa is approx. 1500m (approx 5000ft)

Stratosphere and Polar Vortex Watch 2020
DavidS replied to SqueakheartLW's topic in Spring Weather Discussion
GFS has been showing a significant strat warm in FI for the last few runs. I’d like to see this modelled within D10, but it is interesting nonetheless. The last frame below even hints at a split.- 1,801 replies

Model Output Discussion - Winter arrives
DavidS replied to Blessed Weather's topic in Forecast Model Discussion
ECM perhaps being more consistent with the theme of a generally NW/SE aligned jet, on the whole keeping things on the cool / occasionally cold side. -

It’s going to get pushed through, but it does keep trying. -
Stratosphere and Polar Vortex Watch 2020
DavidS replied to SqueakheartLW's topic in Spring Weather Discussion
GFS 00z develops a decent warming at 10 hpa. It is days 14-16 so could disappear on the next run, but if it models this for a couple of days it will pique my interest.- 1,801 replies

This is terrible news. I only hope it has an effect, and the lockdown is not too long. -

By the end of the 00z op the heights to the SE are reduced but also the heights into Greenland. The control has lower heights to the SE but a less significant push of heights to the NW and into Greenland. A system then pushing south from Iceland introduces a warmer sector for a time. If it could clear to the SE it would be favourable, but don’t think it will.
