Blazing hot temperatures baked the UK last week, with highs of 32.2C on the hottest day of the year so far. However now the heat has given way to cloudy skies, heavy rain and thunderstorms, leaving Brits wishing for another heatwave. This has led to a range of warnings across the UK, from Met Office thunderstorm alerts to flooding.

The Met Office has issued a thunderstorm warning for parts of England and Wales, with torrential rain, strong winds and lightning forecast to hit today.

The warning area covers the East Midlands, East of England, London and South East England, South West England, Wales and the West Midlands.

The Met Office warns: “After early rainfall in the southeast of England, showers and thunderstorms are likely to develop more widely across the warning area during the afternoon.
