A scattering of showers this weekend, and perhaps a few in eastern Britain by Monday. Next week, a change to a north-westerly airflow pattern, with cooler conditions than recently for most. Cloud and patchy rain developing in the north-west, and a gradual deterioration is expected for most places as we move into early August.

High pressure is situated to the west of Ireland on Sunday, whilst low pressure is centred over the North Sea. A cold front moves south-eastwards across England, and this may lead to a few thundery showers, most likely for central and eastern England. Heavy bursts of rain may also affect Scotland, mostly toward the east. Western and south-western areas of England and much of Wales are generally dry with sunny spells, although a few showers may affect west Wales later in the day. A brisk north-westerly breeze around southern and western coasts. Scattered thundery showers for Ireland, mostly in the east. Highs 19 to 25C, coolest north-west Scotland, warmest south-east England.
High pressure remains to the west on Monday and there is a light northerly breeze for most areas, strongest around western coasts. A scattering of showers is possible for the east and south-east of England. Western and northern areas generally dry and bright. The far north-west may see more cloud and patchy light rain as weak fronts pass northern Scotland. Highs 21 to 25C, coolest in the west.
A north-westerly breeze across the British Isles on Tuesday. Variable amounts of cloud across the country, and the risk of a patchy showery rain in the north-west of Britain and Ireland. Central and southern areas dry and bright, best sunshine in the south east. Feeling cooler in Scotland and Ireland at 17 to 22C, but warm for England and Wales at 22 to 27C.
A generally north-westerly pattern remains in place, with low pressure to the north of Scotland. Most likely remaining dry and warm in the south. More cloud toward the north and west, and the risk of some rain for Scotland and Northern Ireland. Highs ranging from 16 to 20C in the north, 22 to 24C in central areas and 26 or 27C in the south.
A slow deterioration in conditions is expected toward the end of the week. Generally cooler for all, with an increased risk of showery rain, particularly in the north and west. Southern areas may remain fair. Highs 17 to 20C north, 22 to 25C south.
The risk that low pressure becomes a more dominant feature close to the British Isles as we start August. Confidence of detail is low, but most likely mixed across the country, with sunshine and showers. Highs 18 to 24C.
