Generally very light winds. Localised heavy showers will form and move around slowly, most widespread in Wales. Risk of thunder. Fairly cloudy; persistently shrouding some hills, but also some breaks. Close to freezing point on Scottish high tops, coldest north & east.
Little wind. Isolated showers, mainly in west. Chilly start.
East or southeasterly, mostly 10mph, sometimes less, but occasionally 15mph Galloway hills.
Negligible
Isolated showers, mainly west
Chance of an isolated shower from dawn, mainly in far west. By afternoon, localised slow-moving showers forming, mainly Dumfries & Galloway, some heavy with risk of hail.
Low cloud may linger in east
Blanket fog may well cover many eastern hills throughout the morning, to lower slopes in places. Slowly thinning back toward the North Sea coast. Further west, patches lifting above tops, only reforming locally around showers.
50% east, rising to 90% west
Bright sunshine in and out, but by midday cloud will largely fill in. Excellent visibility - but abruptly poor in rain.
1C rising to 4 to 7C in afternoon, coolest eastern Cheviots.
Close to freezing on The Cheviot summit early morning, plus slight frost sheltered areas and some valleys at dawn.

Increasingly wet, particularly from late morning Dumfries and Galloway, as areas of discrete showers and perhaps more widespread rain develop, sometimes heavy with hail and risk thunder.
Forming intermittently in rain
Very varied: Near rain, cloud covering many hills, perhaps extensively above about 500m. Here and there fragments from forest canopies up. However, periods where most cloud above the summits.

East to southeasterly, mostly 10-15mph or less.
Small
Localised downpours; risk thunder
Showers mostly by late morning onward. Hit and miss heavy bursts during afternoon. Risk merging into an hour or more of rain locally. Possible hail and thunder.
Lowering around rain
Varied banks of cloud across the hills. Around rain, patches will form to lower slopes, and extensively on higher terrain for an hour or more. Some breaks to higher slopes.
40%
Mostly cloudy, a little sun. Visibility sometimes very good, but very poor during showers.
4C rising to 7C
Above the summits
Low pressure will continue to dominate the weather pattern into next week. Little change to recent patterns, with areas of slow-moving showers and thunderstorms with hail, typically most widespread in the afternoons. As the remnants of fronts circulate slowly across Britain, the intensity and extent of showers will vary from day to day, in places merging to give a few hours of constant rain, but nearby escaping drier. Winds often very light, sometimes strengthening locally. Temperatures around average for mid-May, but at times just below freezing on highest Scottish summits, resulting in occasional snow here. Existing lying snow thawing only gradually on the highest tops.
