Summary for all mountain areas
Strengthening winds, particularly across Scotland, will increasingly bring upland gales to higher areas. Most mountains will be dry with areas of low cloud at first, clearing most tops completely, although cloud will persist on particularly western hills in the NW Highlands.
Headline, The Northwest Highlands
Widespread upland gales. Low cloud, mainly northwest.
Northwesterly 30 increasing to 40mph and possibly 45mph with gusts to 60mph.
Effect Of Wind?
Considerable buffeting across the hills, and on many higher areas mobility difficult. Increasingly severe wind chill.
Snow showers; later heavy toward north.
Snow and hail showers increasingly developing, heaviest Sutherland in the afternoon.
Cloud on the hills?
Fairly extensive on higher areas
Patches of cloud around 650m at first, although well inland mostly above 850m. Through the day, the base will rise, intermittently clearing many summits, although will return near showers, and will often shroud higher coastal summits.
Chance of cloud free Munros?
50% coastal summits to in afternoon 80% well inland.
Sunshine and air clarity?
Bursts of sunshine; generally most cloud western summits. Visibility poor in cloud but widely excellent away from showers.
How Cold? (at 900m)
-1 to 1C. Will feel as cold as minus 16C directly in the wind.
800 to 1000m.
Planning Outlook for all mountain areas from Thursday, 23rd May, 2013
Cold over the coming week. There will be freeze thaw cycles on higher Scottish summits, and on higher tops further south, temperatures often only a couple of degrees above freezing point. Total precipitation will be small, but there will be snow showers (often rain or hail on summits from S Scotland southwards), and occasionally, particularly in western Scotland, fronts may edge in bringing several hours of rain and low cloud. Generally summits will often be cloud free, and the visibility excellent.
