The northerly looks to have some bite with sub -5C at 850hPa even from GFS!
00Z GFS massive warm outlier after T+168.

Yes, there's a big change between yesterday's 12Z and last night's 00Z.
The ensemble mean 850mb temperature is now consistently around -5C all
the way from the northerly setting in out to the end of the run.

UKMO still consistent and fits in with first principles.
ECM hinting at a cool northwesterly eventually but its a long way out,
especially with things happening in the stratosphere.
