Summary for all mountain areas

Gale-force southwesterlies, strengthening to be severe on higher mountains. Rain increasingly persistent from the west, some heavier falls setting in for periods combined with lowering cloud over the hills. Near freezing on higher Scottish tops, where some snow falls for a time.

Headline for Brecon Beacons

Upland gales. Rain increasingly persistent, heavier afternoon.

How windy? (On the summits)

Southwesterly 35 to 45mph, a trend towards the higher end of the range with time and reaching 50-55mph over high terrain afternoon and onward after dark.

Effect of the wind on you?

Strenuous-to-arduous walking all day, strongest wind necessitating notable effort to maintain stability, increasingly difficult afternoon; significant wind chill.

How Wet?

Rain on-and-off, becoming persistently heavier.

Cloud on the hills?

Variable, fairly extensive

Cloud shrouds the high terrain most of the day, often to middle elevations of southern aspects and Cambrians. During rain breaks, bases will lift, a chance of higher breaks Black Mountains, but cloud returns again.

30%

Sunshine and air clarity?

Often cloudy, though a period of brighter skies and some sun through high cloud early in day eastern areas. Mixed visibility, good out of fog/rain, but a haze towards the sea.

20%

Planning Outlook

A changeable southwesterly regime continues through the weekend into early next week. Colder for a time with a drop of freezing level Friday into Saturday allowing some refreezing of higher mountain terrain mainly in Scotland, the snowpack on high mountains consolidating following recent thawing. Milder air and thawing returns into Sunday, accompanied by rain and upland gales. During next week, higher pressure is expected to develop around the British Isles, bringing quieter weather, drier for most with lighter winds. Some fronts may continue to graze northwest Scotland with rain and stronger winds locally for a few more days. Temperatures tending to be on the milder side during early March, but some frosts into valleys at times.
