Headline for Southern Uplands
Clusters of showers; blustery at times
How windy? (On the summits)
Northeasterly 20 to 30mph, occasional breezes approaching 35mph over high tops from the M74 west through the morning. Trending northerly and towards lighter speeds in the west.
Effect of the wind on you?
Feeling noticeably cool on exposed high terrain. Breezy over hills, in places may affect comfortable walking, and likely more strenuous in the morning over some high tops.
How Wet?
Showery rain
A fairly broad cluster of rain just around dawn, local heavy downpours, moving south and becoming a scattering of showers. Periods of more frequent showers return afternoon.
Cloud on the hills?
Clearing many tops, returning to high terrain in rain
At dawn, fairly extensive cloud with patches into sheltered valleys. Beginning to lift from the north, to patches around higher slopes, and increasingly breaking off the tops. Where showers return banks will return to summits with lowest bases on northern aspects to 700-800m.

Planning Outlook
As the weekend approaches, wind shifts northerly, moving showers southward. Generally lighter wind but gusts will be common around showers. Temperature lowers too, dropping close to freezing on high Scottish tops on Friday morning (chance of sleet/snow here) and frost may occur in Highland glens over a couple of nights. Heavy showers in England and Wales on Friday, then more often dry with few lighter showers through the weekend as higher pressure builds into the southwest. Conditions remain on the drier, brighter side into early next week. Wind shifts southwesterly and pressure drops again as the week goes, bringing periods of cloud and rain for most hill groups, and perhaps some stronger wind at times. Detail is uncertain, but some windows of better weather are possible, notably in north and eastern areas.
