Planning Outlook

All mountain areas of Britain from Wednesday 1st April 2015

Wednesday will continue to see upland gales and frequent snow showers, although by Thursday conditions ease, particularly for Scotland, with lighter winds and fewer showers. Toward Easter weekend, a building area of high pressure brings the prospect of quieter but still cold conditions, although there are uncertainties by Monday. For the rest of this week, and also the Easter weekend, many upland areas, particularly the Scottish Highlands will remain in 'winter' condition, with frozen or part frozen terrain and recent snow on higher areas, which will melt only slowly.
