Saturday
Pulses of heavy showers affect the south-west of Britain, later extending into central-southern counties, risk of hail & thunder. A front pivots north across Scotland, bringing persistent rain, most prolonged over the eastern Highlands, plus a strong easterly wind. Early rain in north-east England will fade. Areas of rain also push north across Wales & Ireland. Central & south-east England escape largely dry and bright. Highs 13 to 17C.

Saturday night
Rain extends north-eastwards across England & Wales in the evening and night, local heavy bursts, isolated thunder, but very hit and miss, and some places may escape dry. Clearer spells follow from the south for a time, but further squally downpours are likely to return to south-western areas. Rain across Scotland will slowly fade, but may persist in the far north-east. Temperatures 8 to 12C, locally lower where skies clear in the north.

Sunday
An unsettled day for many areas as low pressure to west pushes areas of heavy showers north-eastwards across the country, some heavy bursts possible with hail and thunder, locally merging into many hours of rain, although precise detail is somewhat uncertain. Scotland and the north-east may escape dry for many hours. Rain in northern Scotland should clear. A blustery southerly wind, strongest in the west. Fairly mild, 13 to 17C.

Monday
Low pressure centred to the north-west, and a front moving away into the North Sea. Any early rain for East Anglia will soon clear. A largely dry and bright day for many places. Showery for Ireland, merging into persistent rain for western Scotland. Scattered showers for many western coasts of Britain, moving increasingly inland. A light breeze from the south-west, strongest in north. Temperatures 12 to 17C, warmest south-east.
