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.
Upland gales. Rain increasingly persistent, heavier afternoon.
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.
Strenuous-to-arduous walking all day, strongest wind necessitating notable effort to maintain stability, increasingly difficult afternoon; significant wind chill.
Rain on-and-off, becoming persistently heavier.
Rain comes and goes, often patchy and light toward eastern mid Wales. Between pulses of rain, spotty rain in the wind continues to affect the southern Brecon Beacons. More prolonged heavier rain increasingly sets in from west into afternoon.
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.

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.

Southwesterly gales overnight ease. Then a lull, but risk increasing N-NW'ly again 25-30mph - high uncertainty.
Uncertain, variable conditions: effects may be small for several hours but a deteriorating trend likely.
Periods of rain
High uncertainty - rain likely affecting most hills at some point through the day, some dry moments too, but also a risk of setting in more widely for several hours.
Extensive, may vary
From dawn, a sheet of cloud shrouds the hills from middle slopes upward, ragged patches to lower slopes too. A lifting and breaking trend away from rain, but if rain lingers or returns, cloud widely lower.
20%
Largely cloudy, some brighter skies may occur, but a veil of high cloud. Visibility poor in rain, but some improvements at times possible.
3 or 4C. Feeling like -5C in strongest wind.

Just above higher summits.
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.
