Sunday
Heavy bursts of rain and thunderstorms are likely to affect eastern Britain during Sunday, whilst western and central areas are drier and brighter as a ridge of high pressure builds in the south-west. Overnight mist and low cloud may linger into the morning, and there may still be a few bursts of rain running into north-eastern England and eastern Scotland. South-east England and East Anglia may see further strong thunderstorms develop through the day, with the risk of hail and torrential rain locally. Any showers are very isolated for the western Midlands, Wales, the south-west and Ireland and there should be some decent sunny spells. Light westerly winds. Temperatures 20 to 25C.
Sunday night
The remnants of thunderstorms will fade overnight into Monday, and there is likely to be a lot of low cloud and mist forming, particularly in areas where rain fell on Sunday. Light winds from the west and north-west. Overnight lows ranging between 9 and 15C for most, coolest in the north-west, perhaps down to 7C for rural Ireland with clearer skies.
Monday
The UK and Ireland are influenced by a col on Monday, sandwiched between pressure systems. For most places it will be a dry and fair day with sunny spells developing. A cloudy start is likely for Scotland and northern England, perhaps with left over rain in the far north-east of Scotland at first. A few residual showers may continue over the Highlands. Weak fronts bring increasing cloud and patchy light rain to the far west of Ireland. England and Wales dry with sunshine and a light north-westerly breeze. Temperatures 18 to 24C for most, locally higher in the south and east.
Tuesday
High pressure centred over Scandinavia also influences the British Isles on Tuesday, with a gentle easterly to north-easterly breeze for most areas. Strongest breeze toward south-eastern coasts. Most places will have a dry, bright and warm day with good spells of sunshine. Central and eastern parts may start quite cloudy but this should thin and break. Isolated afternoon showers may brew up across mostly the higher ground of northern England and Scotland, but unlikely to be widespread. Fronts to the west of Ireland may bring some persistent rain to the far west. Temperatures rising to 25 or 26C inland in southern England, typically 21 to 24C for many, although a few degrees cooler on the coasts, especially in the east.
