Chilly west to southwest winds, strong for a time north Highlands, with showers across western hills, but few if any reaching eastern areas.Cloud bases lifting to higher slopes, but persisting across western tops, whilst eastern hills seeing good clearances with the best of the sunshine, albeit weak due to high cloud.
Mostly dry, bar the odd shower, and a moderate breeze.
West turning southwesterly 15 to 20mph. Uncertain into night, variable then easterly, may start to increase.
Mostly small during daytime. Possible deterioration into night.
Odd showers
One or two brief light showers, mostly west coastal areas. Into night, possibility of some rain developing, may well mostly remain further south, leaving just areas of showers.
Patches western tops, clearing
Some patchy cloud on higher western slopes, mostly above 700m, tending to disperse. Eastern hills largely clear. If rain arrives later, cloud then lowering.
70%
Some sun mostly weakening as high cloud tends to thicken. Visibility excellent.
4 or 5C. Feeling just below freezing in the wind.

Still uncertainty - N-NW'ly may turn toward W, speed likely vary, 25-40mph, may strengthen to 50mph for periods.
Expect blustery conditions and significant wind chill, may deteriorate further to make walking difficult.
Showery, risk constant rain early in the east.
Perhaps early in the day still constant precipitation in east Wales. Otherwise, generally showery, more frequent precipitation on hills nearer to coasts, falling as snow on highest summits, some heavier showers with hail.
Varied on high tops
Often capping higher slopes, varying in and out of showers. Higher breaks more frequent well inland and eastern areas.
40%
Some bursts of sun, mainly east mid-Wales. Visibility varied, poor in showers, intermittently very good.
2C. In stronger winds, chill factor feeling like -10C.
Close to highest summits above 1000m.

Westerly 25 to 40mph
Be prepared for rather arduous conditions through the day with significant wind chill and buffeting for periods.
Clusters of showers
Clusters of showers, some heavy, will edge in from the west through the day. May give frequent rainfall across western mountains.
Fairly extensive
Hill fog likely fairly extensive above 600-800m, with perhaps occasional patches to lower slopes. Breaks to the tops likely to be rather fleeting away from east Wales.
30%
Glimpses of sun through high cloud between the showers. Visibility often poor due to rain.
3C, but feeling more like sub -5C in direct exposure to the strongest winds.
Above the summits
A complex weather situation around midweek with various centres of low pressure drifting around slowly. Areas of rain and showers, but also drier moments - possibly Thursday often dry in eastern Scotland and northern England - beware of a deterioration from the northwest during Thursday with gales and rain setting in. Significantly colder later in the week as winds turn northerly. Freezing level dropping to 800-1000m into the weekend, lowest in northern Scotland. A mix of sunshine and showers falling as snow on high terrain, most frequent in north-facing areas. Falling week, less cold, but frequent rain in the west.
