Northwesterly 5-15mph, lightest wind well-inland where more variable.

Effect of the wind on you?

Small.

How Wet?

Few snow showers

A few snow showers will drift from the north, though many hills remains substantially dry. Falling as rain below 500-600m with time, highest level in the south.

Cloud on the hills?

Lifting to mostly just high summits

A blanket of fog well-inland from Ben Nevis south in the morning, to at least middle slopes. Patchier north and towards the coast. Fog lifts and breaks through morning, mostly just high summits by afternoon, breaks too, but variably lower in showers.

Chance of cloud free Munros?

60%

Sunshine and air clarity?

Bursts of sunshine. Largely excellent visibility.

How Cold? (at 900m)

-2C rising to 0C. Southern islands always at least a degree milder.

Freezing Level

400-500m Creag Meagaidh, patchy frosts in glens. 600-700m for most, lifting to 900m (southern hills nearer 900m early).

Planning Outlook

Chilly temperatures on the mountains most or all week, particularly across the Scottish Highlands where fresh snow in some areas and freezing level sometimes below 750m; some overnight frosts developing in the glens and corries, though always thawing soon after sunrise. Mixed weather with showers drifting around the country, though total rainfall will be fairly small. Wind often light as well, though variable afternoon breezes will form, particularly around showers where gusts may be suddenly strong. Local low fog in the mornings, typically lifting towards or above many summits; a mix of high cloud and sun for most. Detail uncertain into next weekend, but lowering pressure brings an increased risk of wind and rain.
