While for many it is milder today, it will become colder again tomorrow. The main snow risk starts on Thursday where both GFS and ECM show a risk of snow in the south into the midlands and Wales, away from south eastern coastal counties. They both model a low moving in from the Azores, bumping into cold air.
GFS takes this right into northern England and parts of Scotland.
As always, early days and so there is lots of uncertainty. We await the next model run
