How windy? (On the summits)
Low confidence: generally southerly 15-20mph, some risk stronger over high tops, and also chance of a morning lull.
Effect of the wind on you?
Probably fairly small, but a risk of stronger breezes impeding walking on high terrain.

Patchy banks of cloud early at various heights, mostly southern slopes and many clear areas too. Bases lift to largely high terrain, banks may persist for a time near rain, likely dissipating afternoon for clear hills.
Chance of cloud free summits?
Rising to 80% afternoon
Sunshine and air clarity?
Some weak sun through high cloud at times. Good visibility, though reduced in morning rain.

12 or 13C, rising up to 15C eastern hills, may be cooler west.
Freezing Level
Well above the summits.
Planning Outlook
Sunday will be a clearing day for most under a core of high pressure: early rain in Scottish Highlands easing, most cloud lifting off all hills except the north of Scotland, and good sunshine through weakened by high cloud. Temperature more widely mild, warm in Wales. Into next week, a mixed southwesterly pattern remains, windy at times with periods of rain, drizzle and low cloud most persistent in the west. Warmest in England and Wales, but may stay cooler in Scotland as low pressure to the northwest recycles air from the north Atlantic back onto the Munros. Tuesday into Wednesday shows indications of a wetter and windier spell. Pressure generally trending higher later in the week, but extensively settled weather remains elusive until at least the following week.
