Windy, walking impeded
Blustery conditions enough to give buffeting on higher terrain or affect balance on exposed ridges. 25 to 40mph.
Patchwork of cloud and sun
Dry most or all day. A mix of cloud and sunshine. Occasional cloud banks drifting over higher slopes, lifting above the tops.
Hazy, some fog banks

Cloud on the hills?
Varied, mostly south and west
Banks of cloud clinging to hills above 700m most frequently southern slopes and in west Wales, locally lower in morning. May break up to be patchier on tops for a time, with little cloud on north slopes, but tending to increase again late in the day.
Chance of cloud free summits?
50%

Planning Outlook
Frontal rain into south Scotland and north England on Thursday, though details of how the front will move are currently uncertain. Starting on the milder side south of the front, fresher air arrives behind the rain Thursday into Friday, sun breaking out with a few showers - Scottish high summits drop back close to freezing with some snow falling on higher tops. Higher pressure builds on Friday, easing remaining showers with plenty of sun breaking out though a gusty northerly wind will persist for a time. A window of settled weather over the weekend and scope for local inversion conditions. Clear night skies allow for chilly mornings, ground frosts likely, and may remain breezy south Pennines and Wales. Pressure remains high into the next week though a few brief unsettled moments come and go.
