Cloud on the hills?

Cloud may lower from south

Most hills may well start cloud free, but from the south, risk of the base lowering and covering many higher tops, particularly into the afternoon, may become increasingly extensive toward dusk.

80% morning; 60% afternoon

Sunshine and air clarity?

Small amounts of sunshine overall, mostly early morning. Patchy fog on some higher tops. Visibility mainly good away from precipitation.

Freezing Level

700m but lifting, slowly above all summits; a slight frost some inland valleys at dawn.

Planning Outlook

All mountain areas of Britain from Saturday 28th March 2015

Confidence of precise detail remains quite low for Saturday, as an area of low pressure passes quickly east across Britain. Rain and snow clearing east, but expect widespread upland gales. By Sunday and into next week, generally westerly winds, frequently gale force on the mountains, will bring regular precipitation to western mountains in particular. Mostly just higher Scottish summits remaining near or below freezing. Toward the Easter weekend, indications favour periods of north to north-westerly winds, and at least a temporary drop in freezing levels, bringing the risk of snow showers over a day or so.
