Planning Outlook

All mountain areas of Britain from Tuesday 23rd December 2014

The outlook for the Christmas period remains complicated (with into the weekend after Christmas up to 40mb pressure difference near the UK in the numerous model forecasts run by the four main centres). 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 weekend, areas of snow and freezing levels dropping rapidly. Toward New Year, forecasts now overwhelmingly resume often gale force westerly winds & frequent rain (or snow Scottish Highlands).
