Southern Uplands
The Galloway hills eastward to the Lammermuir hills. The Cheviots (including higher hills within the adjacent Northumberland NP).
Monday's Forecast
Windy, walking impeded
Blustery conditions enough to give buffeting on higher terrain or affect balance on exposed ridges. 25 to 40mph.
Sunshine and showers
A good amount of dry and bright weather, but scattered bursts of rain, some may be locally heavy.
Cool to mild
Air temperature 5 to 10C on higher terrain. Comfortable temperatures on lower terrain, but feeling chilly if exposed to wind higher up, especially if stationary. Pack extra layers.

Summary for all mountain areas
Showers scattered across most hills through morning, locally clustering for frequent falls with heavy bursts. Showers gradually clear eastward, spotty light rain fades out with time as sunny bursts break out (though weakened by high cloud). Cool-to-mild, but feeling chilly in a strengthening wind.
Headline for Southern Uplands
Patchy rain gradually fades; becoming windy
How windy? (On the summits)
Northwesterly 15-25mph, orienting westerly and gradually strengthening, to sustained speeds of 25-30mph widely, stronger gusts briefly approaching 40mph.
Effect of the wind on you?
Walking increasingly impeded on exposed high terrain, buffeting in exposure affecting stability with notable wind chill.
How Wet?
Patchy rain eases
Patchy rain from dawn, a few local heavy bursts may form here and there though morning and into afternoon, but a tendency towards drier conditions with just spotty drizzly rain onto western hills later.
Cloud on the hills?
Lowest morning, rising above many tops
Varied cloud banks perhaps fairly widely to low elevations early in day, most notably northern slopes. The base tending to rise to upper slopes through middle of day, breaks increasingly to tops, but cloud caps continue to graze highest tops from the Borders westward.
Chance of cloud free summits?
20% rising to 70%
Sunshine and air clarity?
Largely cloudy to start, glimpses of sun breaking out, more widely with time and particularly on lower slopes. Some thin high cloud moves in from the west. Visibility very good away from showers, some haze in west.
How Cold? (at 750m)
8 or 9C to start, coolest in Galloway. Rising, locally to 11C eastern hills, but soon beginning to cool in Galloway towards 7C, later more widely. Feeling near to freezing as wind increases.
Freezing Level
Above the summits.

West-southwesterly 30 to 45mph, some stronger gusts at times over the high tops.
Effect of the wind on you?
Strenuous walking conditions over the hills, some more arduous moments. Marked wind chill where exposed on high terrain.
How Wet?
Rain most persistent west
Patchy rain and drizzle mostly western hills, becoming more persistent and heavier for a few hours, perhaps remaining quite frequent into evening.
Cloud on the hills?
Often covering western hills, later more widely
Shrouding hills in Dumfries & Galloway perhaps much of the day, lowest bases in rain to 500-600m, or lower coasts. Higher base and more broken eastwards, but tending to fell in more widely with time.
Chance of cloud free summits?
30%
Sunshine and air clarity?
Largely cloudy, some brighter moments mainly east earlier. Visibility poor in rain, better east if drier.
How Cold? (at 750m)
8 to 10C, little change, coolest Galloway. Feeling around 0C in the wind on tops.

How windy? (On the summits)
Southwesterly 20-25mph, some variability, and may strengthen, speeds to 35-45mph over high tops.
Effect of the wind on you?
Fairly small, but comfort of walking at times affected, likely more strenuous later with buffeting gusts and feeling chilly.
How Wet?
Rain most of the day
Frequently raining across all hills, some heavier bursts come and go, and will set in widely for several hours, at least. May break up somewhat late in the day, but staying damp on high tops in the west.
Cloud on the hills?
Extensive
Blanket cloud from 600m up most of the day, regularly lowering around rain and widely lower when rain sets in for a few hours. Any chance of higher breaks early and late in the day but high terrain stays shrouded.
Chance of cloud free summits?
10%
Sunshine and air clarity?
Overcast, dull on high terrain with poor visibility all day.
How Cold? (at 750m)
10C rising to 12 or 13C, staying elevated into night. Feeling like 2 to 4C in strongest wind.
Freezing Level
Above the summits.
Planning Outlook
A generally unsettled outlook during the first two weeks of September with frequent rain and strong winds. Low pressure dominates and a series of frontal systems move in from the Atlantic. West to southwesterlies, often gale force over the mountains in the second half of this coming week. Heavy rain most prolonged in the west where increasingly wet underfoot, streams rising to be in spate. Low cloud often covering the hills, rarely clearing western summits. Temperatures varying, some notably cooler days for Scotland, at times more humid air mainly toward the south. A few brighter windows will break out, mostly south and eastern areas, but always brief and any detail on timing remains uncertain.
