Upland wind in the Scottish Highlands but lighter elsewhere. Frequent showers or drizzle in the morning, falling as sleet or hail on the higher Scottish summits. These will tend to ease in the afternoon causing the extensive morning cloud to lift and break a little.
Cloud and drizzly showers after dawn, then well scattered showers.
West to southwesterly around 20mph. Strongest speeds in the morning.
Fairly small overall, but there may be some buffeting from gusts, most likely in eastern areas.
Patches of rain and drizzle, easing to a few showers.
Drizzly rain over a few hours, most persistent in the western mountains in the morning. Very little reaching the easternmost mountains. Easing into the afternoon when it may fade completely late in the day.
Widespread but lifting into the afternoon
Cloud base may be in the range 500 to 700m, but often a couple of hundred metres higher east Wales. However, fog may descend to lower slopes for periods western mountains. Tending to rise and break a little into the afternoon, once rain eases.

Southerly 40 to 60mph, strongest near the west coast. Powerful down-slopes gusts.
Challenging walking conditions. Gusts will affect your balance and could possibly blow you over. Significant wind chill.
Pockets of drizzly rain
Many regions will remain mostly dry, but pockets of persistent drizzly rain on coastal upslopes. Some of these may penetrate inland at times.
Blanket of cloud
Cloud will blanket the hills from 500m or so up for much of the day, with the cloud base highest towards the north.

Generally humid and windy conditions over the next few days bringing lots of low cloud and some drizzle on western coasts. More organised rain at times from Friday and into the weekend but the potential development of a low pressure near Ireland is giving some uncertainty. Temperatures likely fluctuating over the weekend with higher summits below freezing at times.
