A few spots of drizzly rain occasionally drifting into the mountains from the southwest, may be more frequent for a few hours later morning, but the hills otherwise dry.
Cloud on the hills?
Mostly little
Variable banks of cloud in the morning, these lifting and breaking after sunrise for often clear hills. Occasional caps may graze the high tops.
Chance of cloud free summits?
70%
Sunshine and air clarity?
Largely cloudy, some weak sun through high cloud with occasional brighter moments east. Good visibility.

Planning Outlook
Variable weather regimes in the extended forecast. Atlantic west-southwesterly winds will be dominant, with low pressure to the northwest of the country, brining cloud, rain, and mild temperatures, often followed by sun, showers, and cooler temperatures; rain will be increasingly common to the high Munros, but the snowfall level will lower too during periods of cooler weather, and perhaps to high Lakeland fells too, though any snow unlikely to accumulate here. In the longer term, indications of high pressure increasingly building from the southwest, brining drier, brighter, and milder conditions to England and Wales and occasionally Scotland too, though the risk of occasional rain and cooler temperatures remains.
