All mountain areas of Britain from Wednesday 2nd September 2015

Almost completely dry over the next week as high pressure, centred just west of Britain, dominates. However, not warm, and often cloudy. On Wednesday and Thursday, temperatures on highest tops Scottish Highlands close to freezing point, and even into the weekend, ground frost sheltered areas, mainly valleys at night.
