Summary for all mountain areas
Cold with showery snow in the Highlands, also hail in north. Varied winds, blustery in northern Scotland, moderating for a time central Highlands. In England & Wales, a swathe of gales likely affects the mountains, but still some uncertainty about the northward extent; rain and drizzle, plus low cloud covering many hills.
Headline for Brecon Beacons
Gales likely over mountains. Drizzly rain, low cloud.
How windy? (On the summits)
Southwesterly, after overnight gales, a possible brief lull around dawn to 25mph or less, but likely to rapidly increase again to 50mph in morning, risk powerful gusts 60mph near high tops, elevated passes and locally downslope to east. Lessening only later in daytime.
Effect of the wind on you?
Likely deteriorating soon to arduous walking conditions, making balance challenging, buffeting gusts could knock you off your feet in exposed spots. Considerable wind chill.
How Wet?
Patchy rain and drizzle
In fog on high hills, fine drizzle drifts around in the wind, occasional patches of light rain. Intermittently dry by afternoon, but some patchy rain or brief light showers likely come and go.
Cloud on the hills?
Extensive, may break a little
Covering the hills widely in the morning, blanket cloud to mid elevations or some lower slopes toward south and west for a few hours. Tending to rise a little, some breaks may form above 600m during the afternoon.
Chance of cloud free summits?
20%
Sunshine and air clarity?
A few glimpses of sun to the east where visibility good, but otherwise overcast and dull.
How Cold? (at 750m)
5C rising to 7C. Feeling as cold as -8C in strongest wind.

Planning Outlook
A storm system moves across Britain over the Easter weekend, bringing severe conditions increasingly widely - severe gales over the mountains advancing northwards into Scotland by later Saturday daytime. Rain and hill snow also sweeps northward - a substantial snowfall develops particularly in northern Scotland later Saturday. Colder for all by Sunday with all mountains sub-zero, above 600-700m in Scotland, 800m in England and Wales - hail and snow showers with gales bringing severe chill factor. Milder southerlies develop for Monday, dry for most, but risk of gales especially in the west. A changeable weather regime is expected to continue next week, possibly turning chillier again later in the week.
