Forecast last updated on Thursday 18th December 2014 at 1:51pm
How windy? (On the Munros)
Westerly 60 to 80mph, strongest Cairngorm Plateau. Gusts 85-90mph.
Effect of wind on you?
Buffeting from low levels up, and any mobility very difficult on higher areas. Severe wind chill.
Occasional snow showers; risk lightning
Showers, most frequent near/west of the A9, of hail or snow from just above the glens upward. Fewer showers reaching areas accessed from Deeside. Isolated risk a rumble of thunder.
Cloud on the hills?
Summits occasionally clearing
Cloud will come and go on higher areas near the A9, perhaps only rarely clearing the summits. Further east, cloud may often lift off the summits.
Chance of cloud free Munros?
50% near/west of A9; 70% eastern Cairngorms NP.
Sunshine and air clarity?
Bursts of sun, most widespread toward east. Visibility good away from showers, but suddenly reduced to near zero by cloud and snow. Slight haze.
How Cold? (at 900m)
All mountain areas of Britain from Saturday 20th December 2014
Few days without gales on the mountains up to Christmas. Precipitation almost daily, particularly western mountains. Freezing levels rising above most mountain tops on Sunday, resulting in a significant thaw. Next week intermittent cycles of freeze and thaw, but frequently below freezing on Scottish summits. Indications favour colder air spreading southwards around or after Christmas Day, with freezing levels dropping significantly, leaving most ground frozen from just above most valleys upwards, and snow falling to lower slopes.
