Settled at first, with very warm or hot weather quite widely across the UK. There is a small chance of a few thunderstorms, but most areas will likely be dry. Early next week, a transition to less hot conditions is expected, but with uncertain timing. This could bring an increasing chance of some rain or showers, perhaps thundery, but there is scope for very warm or hot conditions to persist in more eastern and southern areas. Beyond midweek, a rather changeable pattern is anticipated with some rain or showers possible at times, which could be heavy and thundery, but interspersed with drier interludes. Whilst a downward trend in temperature is anticipated, it will still likely be warmer than average, especially in the south and east where hot spells remain possible.

A continuation of the broad themes from earlier in the month at first, with high pressure probably dominating the south and lower pressure more favoured to affect the north and northwest. Temperatures are likely to end up above average overall with a continued, and perhaps higher than normal, chance of occasional hot spells or heatwaves, especially further to the southeast. However, around the turn of the month, there is a signal for perhaps more widely unsettled weather to develop, though the details of this remain rather uncertain.
