Mon 14 Jul London and South East England

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.
