UK Outlook for Tuesday 23 Dec 2014 to Thursday 1 Jan 2015:
Rain over central and southern parts Tuesday should move slowing southeastwards, clearing the southeast early on Christmas Eve. Colder showery conditions to the north, with snow on high ground here, following over the entire UK. The colder conditions then persist for most through Christmas Day and the following weekend with snow even to low levels at times in the north. There is a low probability of some more persistent rain crossing southern parts during the holiday weekend with a risk of snow on the leading edge. Otherwise in the following week there looks to be a gradual return to spells of wet and milder weather interspersed with colder, showery conditions. Generally windy for many throughout the period with risk of gales, these mainly in the northwest.
