A transient ridge of high pressure will bring a cold but mostly sunny day although a few snow flurries on some western hills. Nearly all terrain frozen. Toward dusk, initially near the west coast the wind will increase quickly - ahead of severe upland gales and snow overnight.
Terrain mostly frozen. Light wind; extensive sun.
Northwest or northerly 15 or 20mph at dawn. Will drop through morning to or below 10mph in a prolonged lull. Strengthening toward dusk: southerly 15 to 30mph (strongest west Wales).
Small or negligible but very difficult conditions quickly developing after dark.
Precipitation very unlikely
Isolated light snow flurries western hills morning; otherwise dry.
Little if any
Extensively cloud free. Chance patches coming and going western mountains above 500m afternoon.
Almost certain
Extensive bright sunshine before high level cloud spreads eastward afternoon. Excellent or superb visibility.
-2C.
Terrain partly or largely frozen from valleys up. Through day freezing level rising from 400 to 700m.

Westerly 30 to sometimes 35mph. May strengthen to 40mph middle of day or afternoon.
Considerable wind chill and widely arduous or perhaps in afternoon difficult walking on higher areas.
Showery rain
Persistent snow clearing before dawn. Through day hail and rain showers - but over 2 or 3 hours the precipitation may be frequent or almost constant.
Frequently covering higher summits.
Fog across the hills at dawn in precipitation. Will soon improve markedly as cloud base rises toward 600m, albeit dropping again to or below 400m in rain. Generally highest cloud base will be in east Wales where breaks to 750m.
40%
Bursts of sunshine, mainly east Wales. Sometimes excellent visibility, but abruptly poor in precipitation.
Soon 4C. Will feel as close to minus 10C where exposed to the wind.
Most terrain frozen, albeit freezing level above the summits with rapid thaw.

Westerly in the range 30 to 40mph.
Likely to impede ease of walking and risk strong enough to make walking difficult and wind chill significant.
Snow showers; sometimes frequent
Snow and hail showers, sometimes frequent and threat of the precipitation almost constant over a couple of hours. Mostly rain below 550m.
Extensive
Cloud base varying, between 300m near precipitation and otherwise 500 to occasionally above 750m (generally highest base east Wales).
30%
Occasional sunshine - mainly lower slopes east Wales. Very varied visibility; very poor or appalling in snow, but otherwise excellent.
1 or 2C. Will feel around minus 10C directly in the wind.
Just above highest summits.
Persistent cold most mountain areas, particularly across Scotland next week. Further snow from time to time. England and particularly Wales will have intermittently higher freezing levels resulting in freeze-thaw cycles.
