The Galloway hills eastward to the Lammermuir hills. The Cheviots (including higher hills within the adjacent Northumberland NP).
Tuesday's Forecast
Windy, walking impeded
Blustery conditions enough to give buffeting on higher terrain or affect balance on exposed ridges. 25 to 40mph.
Frequent or persistent rain
Steady rain fairly persistent, occasionally heavy, rather wet underfoot.
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
A swathe of rain and gales sweeps across the Scottish Highlands, moving over the Southern Uplands with time; bright sun breaks and scattered showers follow from the northwest. Patchy rain for western hills of England and Wales, sunny breaks east. Blustery with rain increasing later in north England.
Headline for Southern Uplands
Patchy rain increasingly frequent; blustery, strengthening to gales
How windy? (On the summits)
West-southwesterly 25 to 35mph, gradually strengthening through the day, likely at least 40-45mph widely and gusting up to 55mph.
Effect of the wind on you?
Walking soon strenuous in exposure and increasingly arduous as the day goes, balance becoming challenged in strongest gusts with significant wind chill.
How Wet?
Patchy rain, increasingly persistent, particularly west
Patchy rain and drizzle mostly western hills, becoming more persistent and heavier as afternoon goes with showery rain increasingly spreading east. Rain remains 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 400m, or lower on coast-facing aspects. Higher base and more broken eastwards, chance of a clear Cheviot for a time, but filling in here too as afternoon goes.
Chance of cloud free summits?
20% west, to 60% east, later widely 20%
Sunshine and air clarity?
Patchy sun with very good visibility in the east through morning; overcast in the west, cloud spreading east afternoon with visibility becoming poor in cloud and rain.
How Cold? (at 750m)
9 or 10C, rising to 11C. Feeling below freezing in strongest wind later in the day.

Blanket cloud from 500-600m 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)

How windy? (On the summits)
Southwesterly 25-40mph, variable, and may ease for a time, but a swathe of stronger wind returns late/into night.
Effect of the wind on you?
Walking impeded all day, strenuous moments with notable wind chill; a brief easing of effects later.
How Wet?
A little rain, setting in later
Patchy rain drifts from the west, wettest west of the M74, and many hills see largely just light, drizzly spots of rain. Later, a rising chance of rain setting in persistently and heavy, notably into night.
Cloud on the hills?
Lifting towards tops, most cloud west
Extensive to start, particularly west of M74 where most hills shrouded from lower slopes up. Lifting with time, breaks above eastern summits increasingly. Some high breaks west, but banks regularly returning towards 700m, and may later fill in again.
Chance of cloud free summits?
Rising to 70% east, 50% west
Sunshine and air clarity?
A little patchy sun, weakened by high cloud and more overcast at times. Good visibility, some haze, notably west.
How Cold? (at 750m)
10 or 11C, rising to 12C Cheviots. Feeling just above freezing in strongest wind.
Freezing Level
Above the summits.
Planning Outlook
Strong wind (often gale force on high mountains), patchy rain, and some broader swathes of rain and wind will affect the country from mid-week into the weekend; most notable areas of rain on Wednesday and late Thursday overnight into Friday. A few bright glimpses here and there, but many high summits stay shrouded, particularly western hill groups where cloud will often reach lower slopes. A brief bright window for some on Saturday, but staying windy with scattered showers in northwest areas, rain returning later and into Sunday. The next week remains generally unsettled, and may well bring a deep low pressure systems with widespread gales and swathes of heavy rain. Beyond next week, indications of a more settled regime for a time.
