Summary for all mountain areas

Strong to gale-force winds over high terrain. A lot of cloud, shrouding all western hills, plus patchy rain and drizzle, becoming heavier persistent falls in the west later; a swathe of more intense rain develops for southwest Scotland into northwest England by evening, later into north Wales.

Headline for Southern Uplands

Windy; cloudy with some rain, sustained heavy falls later.

How windy? (On the summits)

Southwesterly 25-40mph, variable, and may ease for a time, then increasing sustained speeds again later in day.

Walking impeded all day, strenuous moments with notable wind chill; a brief easing of effects later.

How Wet?

Cloud on the hills?

Planning Outlook

A series of weather systems moves in from the Atlantic over the next 10 days to bring spells of rain and showers, accompanied by frequently strong to gale force mountain winds. A window of better weather is likely on Saturday for Scotland and northern England, but further rain is expected to move in from the southwest by Saturday night and Sunday, heaviest western Scotland; a risk of more powerful upland gales developing over Scotland into Sunday. Temperatures will vary, mildest toward the south, but some cooler air moves in from the north at times bringing higher Scottish tops close to freezing point.
