I know I bang on about WeatherOnline a lot but they keep adding good stuff. This is a new one (unfortunately for subscribers only) - bar charts showing percentage of ensemble members that sit within a specific temperature bound:
ECMWF 00Z:

ECMWF in particular showing more ensemble members in the sub 5c temperature category as we move into the New Year. Would be also useful to know from these datasets where the operational run sits and where the ensemble control sits.
