Thursday's Forecast
Windy, walking impeded
Blustery conditions enough to give buffeting on higher terrain or affect balance on exposed ridges. 25 to 40mph.
Snow and rain mix
Precipitation falling mostly as snow on higher terrain, rain on low-to-middle elevations, may turn to sleet or rain higher up.
Chilly
Air temperature typically 0 to 5C on higher summits. Feeling distinctly chilly on tops when stationary or where exposed to wind. Take appropriate layers.

Summary for all mountain areas
Blustery and chilly south-westerly winds bringing occasional snow and hail showers, most prevalent across the west Highlands. Rain falling below 500m. Drier for England and Wales, but risk of marked deterioration later for southern and eastern Wales as rain and summit snow edges in from the south.
Headline for Brecon Beacons
Rain, snow tops, moving in afternoon from south. Strengthening east winds too.
How windy? (On the summits)
South to southwesterly 20-25mph at dawn. Then there will be a pronounced lull, before an easterly develops later, perhaps up to 30-40mph.
Effect of the wind on you?
Mostly small; but likely becoming arduous with significant wind chill developing later in the day.
How Wet?
Rain and summit snow later in the day.
Most likely extensively dry morning and early afternoon. Still some uncertainty: but then persistent rain moving in from south afternoon (snow higher tops). Western hills may escape.
Cloud on the hills?
May well clear most summits
Cloud base most likely to lift toward 900m widely. Risk though in precipitation of cloud filling in extensively across the hills.
Chance of cloud free summits?
60% for a time, lowering to 20% later in rain and summit snow.
Sunshine and air clarity?
Any early patchy sun, will give way from south to overcast skies. Visibility excellent but very poor in precipitation later.
How Cold? (at 750m)
2C, lowering to 0C in precipitation later.
Freezing Level
Above the summits, lowering to 800m later in precipitation.

How windy? (On the summits)
South-easterly 15 to 25mph, but perhaps up to 30mph up the west coast and some tops inland.
Effect of the wind on you?
Mostly small, but wind chill still significant where exposed to the strongest wind.
How Wet?
Often dry, but patchy rain possible.
Occasional showers or patches of rain.
Cloud on the hills?
Extensive
Fairly extensive banks of low cloud from lower slopes upwards with limited breaks. These breaks perhaps occurring between cloud layers.
Chance of cloud free summits?
20%
Sunshine and air clarity?
Mostly overcast. Rather hazy with poor visibility where patches of rain occur.
How Cold? (at 750m)
2 or 3C, small rate of change in temperature with height. Feeling closer to -5C in the strongest wind.
Freezing Level
Above the summits
Planning Outlook
A small scale low will pull away early on Friday morning to the North Sea to leave drier and chilly conditions into the weekend with a south to south-easterly airflow developing. Looking further ahead, a colder continental influence may be drawn in on south to east winds, but the extent of this is uncertain. The snow pack across the Scottish Highlands will be enhanced by further spells of snowfall where where fronts edge in from the west, whilst for England and Wales snow accumulating on the hills at times, perhaps in the form of showers from the east.
