Enough agreement and consistency for me.

**At T240, on 28th Dec 2010, mild Atlantic air will have invaded the
UK and the cold of December will be over, at least for a while. An
Atlantic regime will be operative, though the change to this milder
air will probably be slow and messy, with a wintry mix as Atlantic
fronts push eastwards. By the 28th, the majority of the country will
be frost free on a night and precipitation in lowland areas will be of
rain and not snow in almost all areas. Much milder temperatures than
those at present, will be recorded on the 28th in all areas. If the
thaw is rapid, flooding could be a problem for some. **

There you go. Whether the mildness lasts, or the cold returns, is
another matter and not knowable at present, IMO.
