Headline, The Northwest Highlands
Temporary lull developing in upland gales. Extensive low cloud.
Westerly, will increase quickly with height to around 40 to 50mph gusts locally 65mph on higher summits and ridges in morning. Temporarily a slight lull middle of the day early afternoon.
Effect Of Wind?
Walking difficult where exposed on higher areas; particularly near major ridges and through some cols. Significant wind chill.
Pockets drizzle western hills
Many areas dry, but patches of drizzle western, mainly or only coastal slopes. More constant rain likely, especially western mountains south of Ullapool by dusk. Widely saturated underfoot on higher areas; streams in spate due to snowmelt.
Cloud on the hills?
Persistent west; breaking east
Low cloud will shroud western hills most or all day, base 500m; perhaps later below 300m, although may break up for a while in morning. Well inland, clod base mostly above 600m, and east of Achnasheen and Loch Cluanie may occasionally clear altogether.
Chance of cloud free Munros?
30% morning, dropping to 10% afternoon
Sunshine and air clarity?
Pockets of sunshine in morning, Sutherland and lower areas east of Achnasheen and Loch Cluanie. Visibility very good well inland and Sutherland, but a haze toward the west and extensively foggy on most hills.

Planning Outlook for all mountain areas from Sunday, 19th May, 2013
Appreciably armer on the mountains until Tuesday with considerable melting of remaining high level snow cover. Often dry with fairly light winds but mainly on Monday, there could be a few afternoon thunderstorms. Through the week, temperature levels will gradually drop but at least winds will remain fairly light. Total rainfall will be small, although from time to time showers, or occasionally a few hours of steadier rain may develop.
