Summary for all mountain areas

Chilly Scotland, frequent showers over central and west mountains, hail mixed in with snow on summits. Showers spread widely afternoon. Wales and south Pennines start dull and rainy, this soon clearing to cooler, brighter weather. Showers and wind follow in north Wales, then into England later afternoon.

Headline for Brecon Beacons

Early rain and cloud clears for breezy, cool sun, late showers

How windy? (On the summits)

Northwesterly 25-30mph, some stronger sustained speeds possible early, and the strengthening again evening into night, strongest speeds to 35-40mph.

Effect of the wind on you?

Ease of walking impacted in exposure most or all day, walking more strenuous early and late, considerable buffeting in gusts and notable wind chill.

How Wet?

Morning rain clearing to a few showers

Showery rain from overnight will slowly clear through morning. A dry window, then showers follow from the north. The showers generally light but coming in clusters, most notable falls towards western Brecon Beacons/Cambrians.

Cloud on the hills?

Intermittently covering higher areas

Cloud likely to shroud the mountains widely in early rain, but as rain clears, cloud lift and break up into varied shreds, soon clearing most or all summits. During showers, patches reform on tops, locally down to 600m northern slopes.

Chance of cloud free summits?

60%

Sunshine and air clarity?

Cloud with poor visibility to start. Patchy sun breaks out, good visibility, but briefly deteriorating in showers.

How Cold? (at 750m)

6 or 7C, slightly lowering later in the day. Feeling like -2 to -5C in direct wind.

Freezing Level

Above the summits.

10% rising to 70%

Overcast, dull most of morning with poor visibility. Afternoon is mostly sunny with very good visibility.

Planning Outlook

Thursday begins chilly with bright sun, some frosts in sheltered glens and valleys, and a few showers along Scottish and Welsh coasts. Westerly wind returns as Thursday goes, bringing rain, low cloud and strong upland winds across Britain overnight into Friday morning. Friday and Saturday are windy and showery with bright breaks, a risk of severe gales on Scottish tops. Sunday sees a more settled day as a small ridge of high pressure builds from the west. The following week looked mixed with bands of rain coming and going, temperatures similarly fluctuating: generally mild, but sometimes chilly in Scotland with freezing levels lowering onto high Munros and rain turning to snow. Some indications of more settled weather into the following weekend, but confidence is low.
