Summary for all mountain areas
Scotland starts windy with rain in the northwest highlands, this spreading fairly widely over the highlands into afternoon and evening. Wind eases, some bright breaks in the far northwest. Feeling damp, warm, and often cloudy England and Wales, drizzle on west hills, odd patchy rain, but sun glimpses too.
Headline for Southern Uplands
Some drizzle, mostly west, sun breaks too; warm and humid
How windy? (On the summits)
Southwesterly 15 to 25mph, some gusty areas around some higher tops, and sustained 30mph on north slopes early in the day.
Effect of the wind on you?
Varied conditions, in places fairly small, but some more blustery areas and some buffeting gusts, particularly early.
How Wet?
Drizzle mostly west, a few patches drift east
Sometimes drizzly Dumfries and Galloway up to the M74 corridor, generally damp where in cloud, patchier drizzle north and eastwards, substantially dry on many hills. Some steadier rain approaches Galloway into evening/nighttime, deteriorating overnight.
Cloud on the hills?
Most persistent southwest
Shrouding many hills in the morning, from lower elevations upward in southwestern areas. The base tending to drift slowly higher, but variable, and likely to persist much of day near and west of M74. Breaks develop east areas, then returning extensively west into evening, deteriorating overnight.

20% southwest, to 50% northeast.
Sunshine and air clarity?
Largely cloudy, misty over western hills. Some glimpses of sun toward valleys in north and east, visibility good below cloud, some breaks more widespread for a few afternoon hours, but then clouding over west later.

Planning Outlook
A heavier swathe of rain moves east Wednesday morning, soon clearing Scotland but leaving a few showers behind, later clearing England and Wales. Southwesterly winds increase again on Thursday and rain later moves into western Scotland, but elsewhere is likely dry, bright in Wales and much of England. A variable outlook continues next weekend and beyond with high pressure building from the south at times with fairly warm and dry conditions, but Atlantic systems still pass to the north bringing occasional rain and showers toward western Scotland at least, strong wind here with sustained gales in the north. Next week remains on the unsettled side: west-southwesterly wind with bands of rain passing over most mountains, but a trend towards higher pressure brings longer settled windows into October.
