Today | Sunday | Monday

Forecast last updated on Friday 1st August 2014 at 9:57pm

Summary for all mountain areas

Widespread rain, heavy and in places thundery will spread north ahead of an area of low pressure. There is some doubt about the exact position and depth of the low - and hence wind speed and direction. More showery weather will gradually spread north across Wales & N England.

Headline for The Northwest Highlands

Increasingly windy and in afternoon wet.

How windy? (On the Munros)

North or northeasterly progressively strengthen from 10 to later 20mph morning to 25 to locally 35mph by late afternoon.

Effect of wind on you?

Small before in afternoon, buffeting becomes widespread across the hills.

How Wet?

Rain spreading slowly northwestwards afternoon

Isolated showers morning. Steady rain reaching the Great Glen in afternoon (precise timing uncertain) and spreading slowly northwest, probably reaching coastal summits in Sutherland into the evening.

Cloud on the hills?

Most summits clearing for a while, but later extensive

Cloud probable across higher areas most of the day, although may well clear for several hours, particularly western mountains south from Assynt. Cloud will envelop the hills again in rain, particularly eastern and northern hills.

Chance of cloud free Munros?

60% middle of day; later 10%

Sunshine and air clarity?

Thickening high level cloud will cut out the sun. Excellent visibility before becoming poor in rain and widely foggy higher areas.

How Cold? (at 900m)

7 rising temporarily toward 10C western mountains south of Ullapool.

Freezing Level

Above the summits

Planning Outlook

All mountain areas of Britain from Sunday 3rd August 2014

Confidence remains low for Sunday as a thundery low moves northwards across Scotland. There is risk of strong, possibly gale force winds on northern mountains. Next week, winds generally off the Atlantic will bring rain from time to time, mostly falling as showers, and also low cloud, with western mountains most prone.
