The GFS did forecast the cold to sweep south Sunday night - when I looked at the precipitation chart and now this won't be the case

This map is, as Gooner would say, JFF, because these maps are generally garbage by massively overplaying the snow possibility, but it at least demonstrates the cold air digging in behind the southwards-heading PPN band. Incidentally, if you look at the same GFS run the 2m temps at that time are, if you draw a rough line from the Humber to South Wales, at +2c or below for the entire area north of this (away from coastal fringes)
