Showers in Scotland spread east, turning heavy afternoon. Fog lowering to high terrain in the west Highlands, becoming cooler here. Patchy dawn mist England and Wales, a broader low layer of sea fog east of the Pennines, lifting for clear hills; risk of a few late showers in north England. A cool start, becoming mild.
Warm with a mix of cloud and sun; small chance of showers east
South-southwesterly 10-15mph, up to 20mph early in the day. Trending variable in direction and towards lower speeds, perhaps a lull by evening.
Mostly small, through a notable breeze in the morning, some gustiness too (not just on high terrain).
Likely dry
Local showers here and there, the showers generally light and fleeting and concentrated to the Cambrians/mid-Wales. The Brecon Beacons likely stay entirely dry.
Likely cloud-free
Patchy mist in eastern valleys, this soon dissipating after sunrise for cloud-free hills.
Above 90%
Often sunny, though weakened by high cloud, which may thicken at times. Very good visibility, some early haze.
10 or 11C, may rise a degree. Starting several degrees cooler in the valleys, rising to 17C, locally 19C valleys near Black Mountains.

Fairly small, gusts may begin to impede walking.
Scattered showers
Occasional showers, mostly light, and largely in east Wales. A few showers may drift further west.
Soon clear
A layer of cloud above 600m early, most extensive eastern hills, this lifting through morning, likely clearing the summits by midday. Small chance a few odd banks drifting over highest eastern summits.

5 to 8C.

Monday is likely showery, risk heavy with lightning in England. An easterly wind then gradually establishes in England and Wales, chilly nights and mornings with patchy dawn mist and light frosts, this soon fading for warm days. High pressure remains dominant through the week: regularly sunny and pleasantly warm days; summit temperatures often at or above 10C, many valleys will warm toward 20C or higher afternoon. Risk of sunburn in strong sunshine and very dry springtime ground conditions with high risk of wildfire. Detail becomes uncertain into next weekend, but a rising risk of showers and longer spells of rain, mostly England and Wales, and likely turning cooler into the following week as wind shifts northerly.
