Chance of cloud free Munros?
80%
Sunshine and air clarity?
Sun weakens as high cloud thickens during day, more overcast afternoon. Visibility excellent, reducing later near Skye as rain develops.
How Cold? (at 900m)
-1C rising to 3C afternoon. Feeling nearer -5C if exposed to wind.
Freezing Level
700m plus frost inland glens at dawn. Rising to be just above freezing to highest summits during afternoon.
Planning Outlook
Becoming gradually less cold into the weekend as northerly winds ease and then switch toward west-southwesterly. Fewer showers by Friday with sunny spells. A dry start to Saturday, frost at dawn where skies are clear. Rain and lowering cloud moves onto west coast areas during Saturday, persistent rain later western Scotland. By Sunday and Monday, areas of showery rain will pass eastwards during the daytimes, leaving western areas generally drier with cloud breaks afternoon-evenings. South-southwesterlies then prevail for a few days next week, with rain at times Tuesday and Wednesday on western hills, particularly Scotland. A drier and warmer theme later in the week as higher pressure builds.
