Summary for all mountain areas
A lull in the weather as a transient ridge of high pressure crosses Britain. There will be a lull in wind, showers mostly restricted to W & NW Highlands and cloud confined to higher summits. However, deteriorating afternoon western areas: wind strengthening, later snow.
Headline for The Northwest Highlands
Lull in morning (light wind, dry); then deteriorating: windy and snow.
How windy? (On the Munros)
Direction will vary morning; less than 15mph. Through afternoon strengthening to 40mph west coastal summits by dusk and 30mph well inland. Then 60-80mph through the night.
Effect of wind on you?
Small most of daylight; but later afternoon, walking conditions quickly becoming difficult from west.
Snow showers; later snow setting in
A few snow showers morning. An envelope of precipitation will approach the west coast middle of day and extend across region into the afternoon. Snow above 400 to 600m will give areas of whiteout, particularly western mountains south from Wester Ross.
Cloud on the hills?
Intermittent on higher tops
Cloud rare below 800m by late morning, and most cloud confined above 1050m, with highest tops intermittently clearing, although will persist some summits. Deteriorating afternoon as cloud fills in across higher areas, and from lower slopes western mountains south of Ullapool.
Chance of cloud free Munros?
Sunshine and air clarity?
Bursts of sunshine will give way as high level cloud thickens. Visibility excellent but will deteriorate: becoming appalling in snow and cloud.
How Cold? (at 900m)
-3C rising slowly, toward -1C coastal summits by dusk.
500m, although some glens partly frozen after a frost. Will rise toward 700m on and near Skye by dusk.
All mountain areas of Britain from Saturday 25th February 2017
Continued frequent precipitation and upland gales until Monday. Temperatures will drop below freezing point across the Scottish Highlands later Saturday and on higher summits in England and Wales early next week. Through next week, still precipitation from time to time, but higher areas, even into England and Wales will be frequently sub-freezing. Indeed periods of thaw on the Sottish Munros may well be rare.
