How windy? (On the summits)
Westerly 25-35mph. A small risk of stronger winds late in the day.
Effect of the wind on you?

Showers, then patchy rain
Showers drift onto western hills through the morning. Showers will ease afternoon, giving way to patchy rain, more frequent as dusk arrives.
Cloud on the hills?
Banks west, more widely afternoon
Banks of cloud come and go above 700m on western hills from dawn. High breaks east, particularly east of Pen-Y-Fan where summits may be often clear for several hours. Cloud fills in more widely with bases lowering as rain arrives.
Chance of cloud free summits?
60% lowering to 20%
Sunshine and air clarity?
Bright in the east in the morning, gradually becoming overcast. Excellent visibility, turning poor with rain, very poor on high ground.
How Cold? (at 750m)
2 or 3C. Feeling like -8C in strongest direct wind.
Freezing Level
At or above the high summits, though some local frosty patches onto lower slopes at dawn.
Planning Outlook
Cold air spreads widely across the country; staying below freezing over higher mountains most likely throughout the next week with morning frosts to lower elevations. Snow flurries move in onto slopes exposed to coasts; snow most frequent toward north of the Highlands with some locally more substantial accumulations over higher terrain. Sunny and dry for many away from the coasts on the northerly wind. Tuesday and Wednesday are more unsettled: broader areas of snow and rain pass southward with variable wind - navigation could become challenging in the Scottish Highlands on Tuesday with notable snow accumulations. West-northwesterly winds will likely return into next weekend, brining periods of rain and strong winds with intermittent drier, brighter spells.
