It is likely to be warm for most, to very warm and humid in the southeast where there remains a risk of thundery showers. Elsewhere, some sunny spells and variable cloud with fresher conditions. Some showers in the south and along northern and western coastlines, and windier conditions towards the far northwest. The fresher air is then likely to gradually spread to the rest of the country bringing a change to widely cooler more changeable conditions into the new week, with a low risk of warm and humid air returning to the far southeast at times. This will likely bring occasional spells of rain or showers interspersed with drier and sunnier conditions. Overall, temperatures will likely average out to be close to normal.

Low confidence through this period due to mixed and weak signals. Likely to see a mix of occasional Atlantic frontal systems affecting the UK followed by spells of more settled weather through this period. This bringing periods of dry, settled and warmer weather interspersed with occasional days of thicker cloud, rain and stronger winds. Temperatures are likely to be slightly above average, although cooler conditions may occasionally affect the northwest. Meanwhile, very warm perhaps hot conditions could affect the south and east at times. Overall, rainfall amounts will likely be close to average for the time of the year. Whilst the southeast may see fewer spells of persistent rain, thunderstorms may develop during warmer periods.
