All mountain areas of Britain from Monday 22nd December 2014
The outlook for the Christmas period remains complicated (to say the least) with forecasts from the models variation considerably. Until Christmas frequent upland gales, rain, or in Scotland intermittently snow falling to lower slopes. Then a transient high will give lighter winds Christmas Day and perhaps Boxing Day England and Wales. Then further upland gales, and more likely than not over the following weekend, areas of snow and freezing levels dropping rapidly. However, forecasts now overwhelmingly resume often gale force westerly winds & frequent rain (or snow Scottish Highlands).
