Easterly 20 to 25mph.
Mostly fairly small, but expect sudden gusts to develop (sometimes on lower slopes) making balance tricky.
Rain now and again
Low confidence as general of low pressure develops across Britain: Occasional rain likely, mostly afternoon or evening, when there may be heavy bursts.
Patches may form in rain
Most or all hills cloud free, probably all day. But in rain, most likely only later in day fog my begin to shroud some higher slopes, and possibly here and there extend to lower slopes.
80%
Sunshine, sometimes weak, through thin high cloud. Some haze, although generally very good visibility.
17C
Above the summits.
Still a few showers W & NW Highlands on Sunday, and threat of some rain by dusk western mountains. The rain will be ahead of a very complicated weather pattern early next week; areas of rain will drift slowly across central and mainly northern Britain, but the distribution of rain (and associated low cloud) remains very uncertain. Despite some recent rain (mainly in Scotland), away from the W & NW Highlands terrain remains exceptionally dry: 'tinder dry'.
