Looking at all the ECMWF ensembles at day 10 and categorizing them:
Iberian/Bartlett/Euro High (Very zonal): ||||| ||||| || (12)
Mid Atlantic high (northerly): ||||| ||||| | (11)
UK High (anticyclonic): ||||| ||||| | (11)
Greenland high (northerly): ||||| ||| (8)
Atlantic Southwesterly: ||||| (5)
Cyclonic, Average temps: ||||| (5)
Big downgrade from yesterday but still ~50% decent runs. The main issue is rising heights over Europe. The high latitude pattern is overall pretty good but it gets ruined by high pressure building over Europe.
