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. Localised heavy showers. Chilly start.
Direction varied 10mph or less inland. Near west coast and Loch Lomond NP, east or southeasterly, locally 15mph sometimes 20mph.
Mostly negligible
Local slow-moving showers
Isolated hail or snow flurries on higher slopes from dawn. By late morning, localised heavy showers forming with hail. May form into a cluster lasting an hour or more during afternoon, focused on mountains just inland from the coast.
Frequently clearing the summits
Cloud intermittently on higher slopes for a few hours, but by late morning higher summits rarely covered. Will reform around showers, locally patches on lower slopes.
70%
Bright sunshine in and out, but by midday cloud will largely fill in except perhaps coastal mountains. Superb visibility - but abruptly poor in precipitation.
0 or 1C rising to 7C in afternoon.
Near 900m at first with frost sheltered areas and glens at dawn. Will lift above the summits by midday.

Direction varied 10mph or less. May be southeasterly 15-20mph coastal summits.
Mostly negligible
Showers developing
Generally a few brief hail flurries mainly late morning onwards. However, toward the coast and across Loch Lomond NP, risk areas of heavier slow moving showers afternoon onwards.
Mostly very little
Summits extensively cloud free, particularly from mid morning. Near precipitation cloud forming on some hills, mostly above 600m, but here and there pockets from forest canopies up.
60%
Bright sunshine from time to time, mainly morning toward the coast. Superb visibility although abruptly poor in precipitation.
Near or just above freezing point after dawn; reaching 7C in the afternoon.

East to southeasterly, mostly 10-15mph or less.
Small
Localised downpours; risk thunder
Showers forming fairly widely inland by late morning onward. Slow-moving heavy bursts most widespread during the afternoon, although still hit and miss. Risk of hail and thunder.
Lowering around rain
Varied banks of cloud across the mountains. Around rain, patches will form to lower slopes, and extensively on higher terrain for an hour or more. Some breaks to higher slopes.
40%
Occasional sun, most frequent near west coast. Visibility very good, but very poor during showers.
3C rising toward 7C
Above the summits, but highest slopes above 1300m may be near to freezing at first.
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.
