How windy? (On the Munros)

East to southeasterly, mostly 10-15mph or less, locally at times may be 20-25mph.

Effect of the wind on you?

Small, but local gusty conditions possible, in places to low levels.

How Wet?

Rain not expected

Cloud on the hills?

Mostly all clearing

Risk of fairly extensive low cloud from dawn, particularly eastern areas where slow to lift and break. Otherwise early cloud banks breaking up through morning.

Chance of cloud free Munros?

70%

Sunshine and air clarity?

Patches of sun, breaking through increasingly, although eastern hills may hold more cloud. Areas of mist or haze clearing, visibility may well become excellent.

How Cold? (at 900m)

10 to 13C, coolest where in cloud, but locally a few degrees warmer west of the A9.

Freezing Level

Above the summits.

Planning Outlook

Remaining warm and humid through the weekend, particularly in western regions, whilst eastern areas are cooler under North Sea air, which brings a risk of lingering fog banks. The Scottish Highlands stay extensively dry. Thundery rain mostly confined to Wales, although rain may expand back northwards into the Pennines by Sunday. Into next week, light winds and areas of slow-moving showers at first, then a gradual change is likely as windier conditions move in from the Atlantic, with belts of rain or showers.
