Northerly 15 to perhaps on highest tops 20mph.
Small
Brief showers
Risk of a few showers from dawn. From late morning or midday, a scattering of showers more widely, giving hail on higher tops. Small risk isolated thunder. The rain least likely on western hills.
Lifting to higher tops
Cloud banks may cover northern tops in Snowdonia for a few hours in the morning, then lifting toward or above most or all summits into the middle of the day.

Fairly cloudy, although coastal fringes sunnier by afternoon. Visibility excellent.

Direction may well vary, although mostly westerly less than 15mph.
Mostly negligible.
Showers, mainly well inland
Scattered showers morning, most likely Snowdon range. Will gradually change as most showers become confined to more eastern hills whilst toward the coast rain becomes isolated.
Will clear many summits
Cloud base will rise from 550 to 800m (lowest near coast) after dawn to or above 900m by late morning. But in rain, expect fog as low as 650m, temporarily lower.
70%
Patches of sunshine. Very good visibility.
4C.
Above the summits.
Relatively low temperatures on the mountains much of next week; particularly on the Scottish highlands where higher tops will frequently be near freezing point. Showers, some heavy and thundery, giving hail and on higher tops snow, will be widespread, particularly in the afternoons, when in some areas they will merge to give a few hours of precipitation.
