How windy? (On the Munros)
West or southwesterly. Speeds changing, near 50mph at dawn, easing toward 30mph for a few hours during middle of day, but rapidly increasing by mid-late afternoon toward 50 to 70mph, strongest south; risk gusts 80-90mph Loch Lomond NP & Arran.
Effect of wind on you?
Expect very difficult conditions, particularly afternoon toward the central belt and Arran, when any mobility difficult and wind chill severe where exposed.
Frequent snow - setting in
Snow and hail showers will merge into constant, widely heavy snow, giving whiteout. During afternoon, increasingly turning to rain up to 800m, perhaps 1100m toward Loch Lomond NP & Arran.
Cloud on the hills?
Extensive all day
Brief breaks to higher summits mainly well inland morning, but generally mountains covered, and where snow becomes persistent, base will drop to 300 to 600m widely - lowest west.
Chance of cloud free Munros?
Almost nil west; 10% inland
Sunshine and air clarity?
Little if any sunshine. Often hazy and in snow and cloud appalling or near zero visibility.
How Cold? (at 900m)
-3C, will rise to 1 to locally 3C temporarily later afternoon. Feeling as cold as minus 18C directly in the wind.
500m rising to 600m by early afternoon; then late in day temporarily toward 900m, or perhaps 1200m toward south.
All mountain areas of Britain from Tuesday 31st March 2015
Expect cold and showery weather for all mountain regions during both Tuesday and Wednesday, precipitation most frequent over western mountains, snow falling to lower slopes, with freezing level typically 500 to 700m, highest Wales. Widespread upland gales will also continue until mid-week. There is now moderate confidence of much 'quieter' weather as pressure builds over Easter. It may remain cold, but substantially dry and winds frequently light.
