All mountain areas of Britain from Thursday 28th May 2015
Frequently cold over the next week, with precipitation at some stage on most mountain areas more or less daily. Often this will be as heavy showers, with hail and mainly on the Scottish Highlands, snow on higher areas. There will also be thunder. As the cold weather continues, mainly on the Scottish Highlands, there remains considerable snow cover, this blocking access to some routes. There are strong indications of a reversal in weather pattern around the middle of next week, with pressure building in the vicinity of Britain, to bring fine, and later in the week warm weather.
