Summary for all mountain areas
Windy, gales over Scottish mountains and increasingly on higher tops of England & Wales. Rain starts patchy and light but becomes persistent over western hills, extending eastwards with time. Cloud capping most high tops, lowering in rain particularly in the west.
Headline for Southern Uplands
Wind strengthens to gales on tops. Rain extends east.
How windy? (On the summits)
Southwesterly soon widely 30mph from dawn, strengthening, sustained speeds 40-45mph over tops and very gusty for a few hours through middle of day, extending eastward. Later easing from west to 25mph.
Effect of the wind on you?
Walking becomes strenuous, arduous for a few hours in exposure on higher terrain, strongest gusts requiring effort to maintain stability; notable wind chill.
How Wet?
Patchy rain then sets in for a time in west
Drizzle and some light rain in morning around high tops from Merrick to Moffat hills; mostly dry east through morning. During middle of day, steadier rain extends eastward, some heavier falls over an hour or so in afternoon Dumfries & Galloway, extending east. Clearing to a few showers later in west.
Cloud on the hills?
Mostly high terrain, more widely through afternoon
Cloud banks drift over the high tops at times, will also break and lift above tops, best east of M74. Merrick to Moffat hills most often in cloud, lowest bases on aspects facing Solway. Cloud more extensively fills in from west through afternoon. Bases then rise into evening with some breaks forming.
Chance of cloud free summits?
60%, lowering to 20% from the west

Planning Outlook
Changeable west-southwesterlies prevail through mid September; often windy, gale-force winds for periods over higher terrain. A window of drier weather this Friday, then the next frontal system sweeps in overnight into Saturday with a sustained fall of rain moving southeastward, accompanied by upland gales for most places. Improving for better weather on Sunday, then wind and rain returns into Monday, staying showery into Tuesday. A mixed outlook likely continues later next week with rain most frequent in western Scotland. Temperatures varying, some cooler days especially in Scotland, but often fairly mild further south, at times quite warm and humid.
