Windy, walking impeded
Blustery conditions enough to give buffeting on higher terrain or affect balance on exposed ridges. 25 to 40mph.
Sunshine and showers
A good amount of dry and bright weather, but scattered bursts of rain, some may be locally heavy.

Summary for all mountain areas
Heavy rain over England and Wales at dawn clears eastward, followed by showers, sun breaks, and cooler temperatures. Showers soon frequent west Scotland, clustering for sustained heavy rain/hail, sweeping east across Scotland afternoon. Widely windy, powerful gusts around rain.
Headline for Brecon Beacons
Early rain clears, a few showers follow, fading; windy
How windy? (On the summits)
Southwesterly 40-50mph around dawn, soon beginning to lessen with a slight westerly shift, 35-40mph much of the day but finishing near 30mph, and further lessening into night. Always a risk of powerful gusts returning.
Effect of the wind on you?
Challenging to start with powerful gusts making stability a constant challenge. Effects will lessen, though walking likely stays strenuous in exposure until evening, at least.
How Wet?
Early rain clears for a few showers, trending dry
A band of heavy rain passes eastwards over a few hours from dawn into the morning. Breaking up to be quickly dry for a brief window, but then showers follow from west for a time, these fading.
Cloud on the hills?
Lifting after rain, increasingly clearing tops
Blanket cloud across hills from dawn into morning in rain, then a rapid clearance to just ragged patches trending upslope with time and increasingly clearing most or all summits by later.
Chance of cloud free summits?
40% rising to 70% later
Sunshine and air clarity?
Overcast and dull just at dawn, patchy sun breaking out, and becoming increasingly sunny though afternoon. Poor visibility in rain, suddenly very good, though a haze building through afternoon.
How Cold? (at 750m)
Mild 13C from overnight but dropping as dawn breaks towards 10C midday, dropping another degree through afternoon. Feeling like -3C later in stronger wind.
Freezing Level
Above the summits.

Effect of the wind on you?
Increasingly strenuous walking conditions on higher terrain, gusts knocking you off balance, later more challenging.
How Wet?
Little or no rain
Odd spots of drizzly rain in the wind drift onto western hills from the south, rainfall totals small and slopes north of high terrain will be largely dry.
Cloud on the hills?
Varied, mostly south and west
Banks of cloud clinging to hills above 600-700m most frequently southern slopes and in west Wales, locally lower in morning. May break up to be patchier on tops, possibly clearer overall east mid-Wales.
Chance of cloud free summits?
50%
Sunshine and air clarity?
Glimpses of weak sun mostly eastern areas. Hazy, visibility better further east.

Southwesterly 35-45mph, strong gusts over tops, tending to lessen, finishing around 30mph and locally less.
Effect of the wind on you?
Arduous walking with buffeting gusts in exposure, effects tending to ease a bit with time; significant wind chill.

Cloud on the hills?
Often covering high terrain
High tops in cloud most of the day, cloud fairly broadly down to 600-700m in the morning, or lower on southern slopes. A window of higher bases possible afternoon, may clear most slopes north of high tops, but returning evening/night.
Chance of cloud free summits?
30%
Sunshine and air clarity?
Often cloudy but some bursts of sun, best north of high tops. Varied visibility, good at times though often poor on tops, some haze too.

Above the summits.
Planning Outlook
Southwesterly gales strengthen to become severe on the mountains into Wednesday, moderating into Thursday. Cloudy with some drizzle on western hills, a band of more extensive heavier rain passing southeastwards Wednesday into Thursday as well. Starting on the milder side, but fresher air arrives behind the band of rain Thursday into Friday, sun breaking out with a few showers - Scottish high summits may drop back close to freezing with some snow falling on higher tops. Indications of higher pressure building on Friday and into the weekend, bringing a window of more settled weather and scope for local inversion conditions on high terrain. Clear night skies allow for chilly mornings, some ground frosts likely, and may remain quite blustery south Pennines and Wales.
