Effect of the wind on you?
Fairly small, but some more blustery moments on high tops early. Walking becomes impeded again late in the day, further deteriorating into night.

Scattered showers, driest far east hills
Scattered showers through morning, a little summit drizzle too, mostly west, some chance of scattered showers afternoon too but many hills stay dry, particularly Lothians to Cheviots. As night approaches, patchy rain returns from the west.
Cloud on the hills?
Early cloud increasingly breaks off tops
Cloud most extensive on slopes facing Ayrshire into the Central Belt to start, banks at varied heights further south, little if any east. Cloud lifts and breaks up, largely above the summits through afternoon. Passing patches may return to the summit of Merrick late in the day.
Chance of cloud free summits?
Rising to 80%
Sunshine and air clarity?
Mostly sunny, high cloud thickening from the west later. Very good visibility.

Planning Outlook
Showers and strong westerly wind prevails from Thursday into the weekend - areas of low pressure passing north of Scotland with frontal systems bringing bands of rain, followed by showers, wettest over western mountains in Scotland. Periods of gale-force winds over higher terrain, cool temperatures with significant wind chill, particularly in the north where temperatures will occasionally approach freezing point on high Scottish tops. Showers generally more scattered in England and Wales, most showers in the west; bright spells too, but bands of rain and low cloud will pass these areas. Mild temperatures, at times warm south Pennines and Wales. Milder, more settled weather is indicated next week, though sometimes breezy in Scotland, spells of rain in the west.
