Headline for Southern Uplands
Blustery, clusters of showers, mostly west
How windy? (On the summits)
Westerly 40mph at dawn, briefly longer in the east, but soon easing to 25-30mph. Notable gusts around showers, and trending northwesterly with time.
Effect of the wind on you?
Blustery across the hills, affecting comfortable walking with some buffeting in exposure and marked wind chill. Walking more strenuous around dawn, particularly eastern summits.

Showery rain most frequent west
Overnight rain likely clears eastward around dawn. Then showery rain frequent in the west, but becoming more widespread, scattered heavier bursts moving eastward in afternoon, then breaking up late in the day.
Cloud on the hills?
Mostly western high terrain
Banks of cloud come and go above 700-800m, more frequent in Galloway, some patches to 500-600m in showers. More often clearing tops toward and east of the Borders; just around dawn, these areas may be under a broader sheet of cloud, soon clearing away.
Chance of cloud free summits?
50%
Sunshine and air clarity?
Patchy sun west, frequent east, a few cloudier moments. Visibility often very good, reduced in showers.

How windy? (On the summits)
Southwesterly 25-30mph, strengthening, towards 35-45mph, strongest northern hills with notable gusts too.
Effect of the wind on you?
A blustery start, walking increasingly strenuous, buffeting gusts affecting stability; considerable wind chill.

Showers drift from the west, well-scattered to the east and perhaps often dry east Borders/Cheviot for a time, but showers become more frequent, a few heavier falls, and some extended falls west Galloway later.
Cloud on the hills?
Banks over west summits, later filling in
Cloud patches at varied heights to start, most tops covered, and most extensive Galloway slopes, soon lifting with breaks off summits, summits east of M74 substantially clear. Banks return to tops during showers, mostly west where will fill in somewhat later.
Chance of cloud free summits?
80% east, 60% west, lowering to 30%
Sunshine and air clarity?
Patchy sunshine, more often sunny east, and later more cloudy west. Good visibility, but a building haze west and variably deteriorating in rain.

Freezing Level
Above the summits.
Planning Outlook
A brief window of brighter weather on Wednesday, though some scattered showers around and feeling fresher in cooler temperatures. Showers and strong wind return on Thursday, and then the weather stays often unsettled during the next week as westerlies prevail - areas of low pressure passing north of Scotland with frontal systems bringing bands of rain, followed by showers, wettest over western mountains in Scotland. Often windy, sustained periods of gale-force westerly winds over higher terrain; significant wind chill, particularly in the north where temperatures will occasionally approach freezing point on high Scottish tops. A brief window of high pressure may form Saturday into Sunday, and a chance of a window of higher pressure the following week, but confidence is currently low.
