Showers; less windy.

How windy? (On the Munros)

Showers

Scattered showers throughout the day (sleet highest tops), most frequent morning northern Cairngorms NP and Lochnagar areas. Pockets drizzly rain, mainly west of A9, evening

Cloud on the hills?

Confined to higher areas; and increasingly clearing

Overall, cloud base lifting, with summits free of cloud by about midday. But Cairngorms & perhaps Lochnagar will be slower to clear, with cloud widely above 750m at first, and by midday 1050m, or perhaps N Cairngorms still few breaks above 900m.

How Cold? (at 900m)

4C rising by only a degree or two through the day: distinctly cold for August.

Freezing Level

Just above the highest summits, but slight frost in some valleys and corries until after dawn.

Planning Outlook

All mountain areas of Britain from Thursday 21st August 2014

Remaining cold on the mountains - and also at night in many valleys with ground frost some nights - until Sunday. The air very clear and many summits free of cloud during the day; although there will continue to be showers - these dying out through the weekend. Rain and areas of low cloud will come in early next week as an Atlantic low approaches and then crosses Britain.
