High pressure resides across Britain. Little wind overall. Very clear with a good amount of sun, but also some areas of cloud, which will produce one or two localised showers, these mostly just isolated flurries of hail or snow. Temperatures rising just above freezing point on many summits, except the very highest tops in Scotland.
Light winds. Local showers. Hills mostly clear.
Northeasterly, 5 to 10mph, or nearer 15mph toward dusk.

Local heavy showers
A scattering of showers forming through the day, heavy in places with hail, or snow on highest slopes. Where these do form, they will move around slowly for an hour or so. Some areas may miss them completely.
Little if any
Fragments of cloud may briefly form on higher slopes in morning, otherwise most cloud which forms will be above the hills. Brief patches below 700m if showers occur.

High pressure is expected to influence our weather patterns beyond the middle of April. Often dry. Temperatures near freezing point on higher summits, tending to rise most afternoons. Lying snow on higher terrain will thaw only slowly. Some further overnight frosts. Next week may become milder with time. Sun and variable cloud; most mountains often clear. Mostly light winds, but southerlies strengthen this weekend. A frontal system coming in from the west by Sunday-Monday is likely to bring low cloud and some rain for a time, mainly in the west.
