Planning Outlook
All mountain areas of Britain from Wednesday 12th December 2018
A battle between cold air to the east and milder air to the west will take place later this week, with confidence low about the general developments into the weekend. It looks increasingly likely that for a couple of days at least, freezing levels will drop markedly, and there is scope for some snowfalls, chiefly on eastern hills. As fronts push northeastwards, there may be a more organised fall of snow into the weekend. Cycles of freeze and thaw are then likely. Winds varied, up to gale force at times, giving severe wind chill.
