East to southeasterly, mostly 10-15mph or less, perhaps 20mph locally.
Small
Localised downpours
Showers forming by late morning onward. Hit and miss heavy bursts during afternoon. Possible 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. Low cloud may fill in at times on easternmost hills.
40%
Occasional sun, cloud filling in. Visibility very good, but reduced locally around 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.
