Southern Uplands
The Galloway hills eastward to the Lammermuir hills. The Cheviots (including higher hills within the adjacent Northumberland NP).
Wednesday's Forecast
Windy, walking impeded
Blustery conditions enough to give buffeting on higher terrain or affect balance on exposed ridges. 25 to 40mph.
Patchy rain or drizzle
Rain on and off, or generally drizzly - total amounts small, but may be persistently damp, especially where hills are shrouded in cloud.
Warm
Comfortable temperatures on the hills, 10 to 15C on tops, feeling pleasantly warm especially on lower ground. Beware of feeling cooler if exposed to wind on higher terrain.

East Scotland, the Pennines, and Wales start cloudy, this lifting, dissipating over much of Scotland. Early showery rain and cloud in Wales migrates to England and southwest Scotland, thundery showers following over Wales and England; driest/clearest northwest Scotland. Warm, humid, and breezy.
Headline for Southern Uplands
Breezy, gusty; bursts of rain arrive, most in the west
How windy? (On the summits)
East-southeasterly 25 to 30mph, in places gusty 35mph, particularly western hills, where may approach 40mph in the early morning.
Effect of the wind on you?
Blustery, some notable gusty areas may suddenly affect balance around high tops and locally downslope to the west; walking more strenuous in the earlier hours.
How Wet?
Patchy rain, least in the morning
Spots from high cloud, some chance a few odd heavier bursts. Rain becomes more frequent, some steady, heavier falls arriving in central and western areas, tending to drift northward.
Cloud on the hills?
Varied, mostly above summits west for a time
Cloud shrouding hills above 500-600m early, some lower banks toward east. More broken west and lifting, much cloud dissipating for a time, mainly toward Ayrshire slopes, though cloud will return here as rain arrives, perhaps quite extensively. The Cheviot will often but under cloud.
Chance of cloud free summits?
Rising to 60% central and west hills for a time
Sunshine and air clarity?
Occasional weak sun through high cloud, often overcast. Visibility good at times, but reduced in rain, some haze.
How Cold? (at 750m)
11C rising to 14 or 15C, mildest on slopes towards Ayrshire. Feeling like 4 to 6C in strongest wind.

Cloud on the hills?
Fairly extensive
Most slopes shrouded just at dawn, lifting towards high terrain for a time in the west; eastern hills unlikely clearing above 600-700m. Returning extensively to middle slopes as rain arrives, patches increasingly lowering.
Chance of cloud free summits?
30%
Sunshine and air clarity?
Patchy sun through morning, some haze at first, trending overcast and increasingly dull as rain and cloud arrive.

How windy? (On the summits)
Variable 10-15mph, orienting generally westerly, some local breezes approaching 20mph.
Effect of the wind on you?
Mostly small.
How Wet?
Persistent rain, heavy east
Rain rarely ceases on hills near/east of the M74, heavy bursts and risk of thundery downpours. Lighter westward, may break up for periods, notably later. Fast-flowing streams, risk local flooding.
Cloud on the hills?
Extensive
Cloud shrouds the hills in the morning, widely to middle slopes, to lower north and eastern hills. May locally lift, but eastern hills covered likely all day. A few higher breaks may begin to form late in the day, though low chance reaching summits.
Chance of cloud free summits?
20%
Sunshine and air clarity?
A few brighter glimpses may break out west, but otherwise overcast, often dull with poor visibility.
How Cold? (at 750m)
12 to 14C.
Freezing Level
Above the summits.
Planning Outlook
Heavy, thundery rain likely affects England, Wales & southern Scotland on Thursday and Friday, potentially prolonged heavy falls bringing a risk of local flooding. A westerly wind will establish into the weekend, drawing cloud and drizzle onto western high terrain, several frontal systems sweeping more broadly across the country. The strongest wind and heavy rain may pass mostly across England and Wales, with the lightest rain in west Scotland. Best chance of cloud base rising towards higher terrain in western areas, perhaps briefly to higher summits, but the hills more often shrouded, patches to low slopes around heaviest rain. A west-southwesterly weather track prevails next week: cloud and drizzle on western hill groups (particularly west Scotland), breezy, areas of rain regularly spreading more widely.
