England will be hit by thunderstorms tomorrow with parts of the parched country expected to see more rain in several hours than over the whole of last month.

The Met Office has issued a thunderstorm warning for southern England including London as well as the Midlands and South Wales tomorrow from 9am until 6pm.

Up to 15mm (0.6in) of rain could fall in less than an hour, while some places could see 40mm (1.6in) over several hours from successive showers and thunderstorms.

Met Office data shows England had 32.8mm (1.3in) of rain last month, almost half the usual for May average. It was also England's driest spring since the 1890s.

Frequent heavy showers and thunderstorms are expected for much of tomorrow before fading from the west during the mid to late afternoon, the Met Office said.
