It doesn't look hugely different to the 06 or 00 UTC runs to me, to be
honest - zonality ramming in. A bit chillier 25th to 27th Dec.


I have to disagree. The Russian high collapses far faster allowing the upper
trough axis to be further east. The cold advection off the Arctic east of
Greenland consequently digs further south rather than heading WSW as in
previous runs. What I hadn't remembered was that it ties in with the ECM 00Z
ensembles quite well.
