A damp atmosphere shrouds most west coastal hills in fog to lower slopes in morning. Some breaks forming for England, Wales & eastern Scotland. Rain heavier in middle of the day in western Scotland, spreading later to NW England and N Wales.
Mostly dry, wind fairly light. Cloud breaks best east.
North turning northwest later westerly, 10-15mph, tending to strengthen to 20mph afternoon, locally 25mph higher tops by evening.
Fairly small, but likely to impede ease of walking on high tops later in day.
Mainly dry; risk of a little rain
Often dry. Local pockets of drizzle or the odd shower possible. By evening into night, increasing risk of steadier rain arriving from the west.
Most persistent west Wales
Risk of persistent low cloud on western hills near Cardigan Bay, including Preseli hills. Further east, higher cloud, some breaks, but risk of lowering cloud enveloping many hills from west.
50%
Occasional sun mainly east Wales. West Wales mostly dull and misty, but eastern areas may keep very good visibility.
13C, rising marginally middle of day; but will then fall gradually into the night toward 6C.

Southwesterly 15 to 25mph, becoming variable, speeds may fall light later in day.
Some buffeting on exposed higher terrain, may tend to ease.
Rain or thundery showers
Some uncertainty: Rain arriving in the early hours likely to persist well into the daytime, risk of steady heavy falls for many hours. May gradually break up, only to be replaced by slow-moving heavy showers, risk thunder.
Fairly extensive
Blanket low cloud likely to shroud the mountains most or all day, to lowest slopes near west coast. Some breaks may occur above 600m in east Wales if rain fades away for sustained periods.
20%
Generally cloudy, very murky around rain. Occasional improvements.
8 to 10C, coolest toward evening.

Easterly 15 to 25mph.
Fairly small, but locally blustery and gusty through passes to some lower slopes.
Drizzly rain may linger
Areas of drizzle or light rain may come and go through the day, particularly east Wales. Hills toward the west may see very little.
May persist higher slopes
Risk of extensive low cloud across the hills in the morning, to some lower slopes. Gradually cloud bases will lift away from rain, with breaks forming to 600-800m, best in west Wales, but higher tops may struggle to clear.
30%
Mostly cloudy, dull for periods, but visibility very good away from rain.
9C rising to 13C.

Low pressure drifts slowly southwards across Britain through Friday into the weekend, followed by improving conditions from the north as pressure builds. Residual areas of rain, drizzle and low cloud may affect Wales, the Pennines and perhaps eastern Scotland through the weekend, whilst west & northwest Scotland become fine and increasingly warm. Most indications favour high pressure influencing Britain into next week, bringing mainly dry and warm weather. Despite some rain this week, most mountain areas will remain very dry underfoot: beware of the risk of fire.
