Wednesday starts with thunderstorms in eastern Scotland. Elsewhere there are a few showers but it is mostly dry. This morning sunny periods develop widely and the storms in eastern Scotland move away. However, thunderstorms will be breaking out elsewhere and during the second half of the day some severe ones are expected. They bring the likelihood of downpours, hail and flash flooding. Southern counties of England probably see the worst conditions. 

Temperatures range from 21C (70F) in the far north west to 35C (95F) in the south east and East Anglia. See the rain and lightning radar for the latest view.
