How windy? (On the summits)
Southwesterly 30-40mph, powerful gusts likely over high terrain and downslope to the east.
Effect of the wind on you?
Conditions often arduous in exposure, feeling chilly despite mild temperatures, gusts persistently challenging balance.

Cloud on the hills?
Fairly extensive
A blanket of cloud shrouds the summits all day, high terrain mostly in cloud too with bases often down to the middle slopes in the west. During drier periods, bases may rise to upper terrain of the Black Mountains, but any summit clearing will be rare and brief.
Chance of cloud free summits?
20%
Sunshine and air clarity?
A few glimpses of sun to the east where visibility good, but otherwise overcast and dull.

Planning Outlook
A brief lull in unsettled weather on Thursday with mostly dry, sunny conditions and lighter wind. Atlantic weather patterns and west-southwesterly winds follow behind on Friday and into the Easter weekend, but day-to-day detail is uncertain. Temperature and wind will be variable, periods of gales and possibly often cold over the mountains with snow and hail showers at times to lower elevations at least in Scotland, sometimes more widely. Precipitation generally most frequent west and northwest, though bands of heavy rain will sweep east at times. Some brief windows of drier and brighter conditions, as well as milder days in England and Wales, occasionally milder Scotland too, but soon followed by more Atlantic low pressure.
