As of the 12z runs today, for 7-9 days from now...
Cold spell of exceptional magnitude for the time of year, with widespread scattered showers that could at times turn wintry even to low levels: ECM, GEM, UKMO (all lined up at +144).
Cold diverted east of the UK, warmer but unsettled with lows tracking through the UK: GFS, ICON
In between the two - glancing blow from the cold air - cool days and cold nights, some showers - mainly in the east: JMA.
As Phil G says, the reality is often a blend of ECM and GFS, so JMA may be onto something here.
