How windy? (On the summits)
Northerly, gradually strengthening from 10mph or perhaps less, to 30mph.
Effect of the wind on you?
Negligible most or all morning; by evening, impeding ease of walking on some higher areas.

Increasingly wet: risk thunderstorms.
Bursts of heavy rain and in Galloway risk thunderstorms developing during morning. Generally deteriorating as the rain, thundery in places, becomes widespread or incessant.
Cloud on the hills?
Increasingly extensive
Considerable variation both through the day and sometimes between adjacent summits. Generally deteriorating as cloud fills in following onset of rain, quite widely cloud forming on lower slopes. However, even in morning, patches of fog from some lower slopes up.
Chance of cloud free summits?
40%
Sunshine and air clarity?
Little or no sunshine - increasingly dull. Hazy, and visibility deteriorating markedly as rain develops.

Planning Outlook
A slow-moving area of low pressure will leave areas of rain and showers later this week, plus varied banks of low cloud across the mountains, feeling cool. Improving at least temporarily into the weekend as pressure rises for a time, becoming warmer, but southerly winds will strengthen ahead of lowering pressure over the Atlantic, likely to move in by early next week to bring changeable conditions, rain at times, most frequent western Scotland.
