How windy? (On the summits)
Northeasterly 30-45mph, a gradual easing towards the lower end of the range.
Effect of the wind on you?
Arduous walking in exposure, accurate foot placement and balance constantly challenged. Severe wind chill.
How Wet?
Morning snow trends showery
Morning snow fairly widely trends lighter and moves southward, breaking into a more showery regime, most regular north of the A5; may remain snowy towards mid-Wales for longer with rain up to 400m.
Cloud on the hills?
Extensive early, lifting and breaking
Cloud shrouds most mountains from 500m up early in the day. A lifting trend with time, perhaps to just the higher summits by afternoon with a chance of some summit breaks late in the day - timing of improvement is uncertain.
Chance of cloud free summits?
Rising to 50%
Sunshine and air clarity?
Overcast early, glimpses of weak sun breaking out later. Very poor visibility in snow, improving as snow eases and cloud lifts.
How Cold? (at 900m)
-3 or -4C, trending cooler with time. Feeling like -20C or cooler exposed to direct wind.

How windy? (On the summits)
Northwesterly 20-25mph, shifting west then southwesterly, easing for a time, then deteriorating evening and overnight.
Effect of the wind on you?
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 northern hills in the morning, but otherwise dry.
Cloud on the hills?
Patches on high terrain
Cloud caps come and go on the high tops, some bases may be lower on northern slopes early in the day but unlikely dropping below 700-800m.
Chance of cloud free summits?
70%
Sunshine and air clarity?
Mostly sunny, extensive on low inland slopes. High cloud approaches from the west with time. Excellent visibility.
How Cold? (at 900m)
-3C, rising a degree.
Freezing Level
Terrain widely frozen from dawn, thaws up to 400-600m 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.
