Summary for all mountain areas

Strong, gusty wind all day, gales in Scotland, risk severe coastal northwest. Persistent early rain in Scotland breaks to heavy showers, frequent west, clusters spreading east. Several hours of heavy rain sweeps east across England and Wales; driest start Pennines, and dry windows later in Snowdonia and Lakeland.

Headline for Brecon Beacons

Often raining well into the day, breaking west; blustery

How windy? (On the summits)

Southwesterly 30-35mph, some variability, gusty too. An easing trend afternoon, towards 20-30mph.

Effect of the wind on you?

Strenuous walking in exposure through morning with buffeting gusts and notable wind chill. Effects tending to ease afternoon, though staying blustery in exposure.

How Wet?

Rain well into the afternoon, often heavy, easing west

Patchy rain and drizzle from dawn, soon setting in from the west, persistent for several hours with heavy falls, most extensive southern slopes. Tending to ease from the west afternoon, but lingering over eastern hill groups, perhaps well into the day. Later, only scattered showers west, and perhaps largely dry.

Cloud on the hills?

Variable, most southwest, more extensive for a time

From dawn, cloud shrouds the high tops, variable lower banks, mostly west of Brecon and south. Soon filling in widely to middle slopes as rain sets in for several hours, to lowest southern slopes. Cloud breaking from the west later, summits at times clear, but returning above 700m in showers.

Chance of cloud free summits?

10%, later rising to 40% west

Sunshine and air clarity?

Mostly cloudy, dull for several hours as rain sets in with poor visibility. Glimpses of sun from the west later with good visibility.

How Cold? (at 750m)

6 or 7C. Coolest in the west, and beginning to cool afternoon into evening, likely cooling several more degrees overnight. Feeling as cold as -5C in direct wind.

Freezing Level

Above the summits.

Planning Outlook

Saturday stays showery, heavy at times with hail, most frequent and heavy in Scotland and northern England. Sun between the showers, conditions improving from the south, and then the weather more widely settled on Sunday: light or negligible wind, often sunny with chilly morning temperatures, though widely rising by at least a few degrees. High pressure north of Scotland next week facilitates east-to northeasterly winds, which may be quite blustery and gusty at times. Generally cooler temperatures too. Occasional light showers drifting from the east, notably early week, snow flurries on higher terrain. Variable freezing levels, likely lowest early in the week, and also some valley frosts at dawn. A mix of cloud and sunshine, most often sunny to the west of high hill groups where temperatures more mild.
