Fairly extensive morning, variable afternoon, mostly high terrain
A sheet of cloud soon shrouds most hills from 500m upward, lower bases south and west, to 300m or locally lower. From noon, bases lifting with a few breaks forming far east, bases returning above 600-800m during heaviest showers; always lowest bases east.
Chance of cloud free summits?
40%
Sunshine and air clarity?
Some glimpses of sun afternoon in the east; sunshine unlikely on western hill groups. Visibility occasionally good below cloud, but reduced in rain, at times poor.

Shrouding many hills much of the day, from low-mid slopes upward southern areas, highest bases toward eastern mid-Wales.
Chance of cloud free summits?
20%
Sunshine and air clarity?
Overcast, mostly dull, poor visibility in rain, locally better if dry northern areas for a time; may start to improve later.

Planning Outlook
Friday sees a slight settling trend compared to recent days with sunny spells in east Scotland as well as England and Wales, some patchy showers. Unsettled again over the weekend, as southwesterly flow draws several areas of rain across the country, best of dry slopes to the northeast. Showers affect most hills Monday and Tuesday, lowest cloud and most persistent rain along western slopes, but with some breaks as well with sunshine. Wednesday is likely more unsettled as gales spread across most tops and heavy rain drives into northwest England and Scotland. Conditions settling into the weekend as high pressure builds from the south. Low cloud will gradually dissipate for increased sun. Scotland slower to settle, some cloud and drizzly rain lingering in the west.
