Mostly small, increasing wind through the afternoon will bring a marked wind chill.

Cloud breaking off many hills.
Patches of cloud at first, mainly mid to upper slopes, some hills clear. These banks more widely will lift off the tops, although patches may persist west coast.

West to southwesterly 50 to 70mph, stronger gusts likely over exposed higher terrain.
Difficult conditions over the mountains, gusts could knock you over. Significant wind chill from mid-heights upward.
Heavy rain, later snow & hail
Heavy rain focused on western mountains, may last much of the day. An abrupt transition to snow on high tops as this finishes by evening. Then into night, showers with snow & hail falling below 600m.
Extensive
Shrouding most mountains all day, to lower elevations near the west coast.
20%
Overcast and dull. Visibility generally poor.
3 to 5C. Wind chill feeling like -5 to -10C on tops.
Soon well above the summits. Then into night, likely to fall rapidly, below 800m by early Friday.
Mixed westerly patterns prevail this week, but turning northwesterly toward the weekend allowing much colder air to move in - dropping extensively below freezing point over all British mountains for several days. Fresh upland snowfalls, concentrated toward the west and north of the Highlands, including heavy showers with hail. A period of sustained gales over the tops late this week and likely into the weekend - severe gales over Scottish tops on Thursday at least; significant or at times severe wind chill factor.
