Last updated Wed 11th Feb 26 at 4:09PM

How windy? (On the summits)

Northwesterly 20-25mph, shifting west then southwesterly, easing for a time, then deteriorating evening and overnight.

Fairly small most of the day, though some uncomfortable gusty wind early and late in the day.

How Wet?

Little or no precipitation

Some light snow flurries may affect western hills/Cambrians in the morning, but otherwise dry.

Cloud on the hills?

Odd caps on summits

Occasional cloud caps over the summits, but most hills substantially cloud-free.

Chance of cloud free summits?

90%

Sunshine and air clarity?

Mostly sunny. High cloud approaches from the west with time. Excellent visibility.

How Cold? (at 750m)

-2C, rising a degree.

Freezing Level

Terrain widely frozen from dawn, thaws up to 500-700m with time, highest where sun-exposed.

Planning Outlook

Colder for all areas during the transition into the weekend, mountain terrain frozen to increasingly lower elevations - soonest toward the north and east of Scotland. A widespread frost early on Saturday. Northeasterly wind will be dominant - the distribution of snow showers shifting with time from eastern hills to more north-facing mountains, particularly Scotland. Brighter than recently with sunshine and clearer hills later Friday and Saturday. Gales with heavy snow (rain to increasingly higher elevations) overnight into Sunday brings a return to unsettled weather for the following week - wet and windy periods come and go, freezing levels rising (high Scotland terrain stays frozen), then lowering again during periods of northwesterly wind.
