I can give you the forecast for East Anglia now if you like
Away from East Anglia (where it will be cool and cloudy) temperatures will climb rapidly, possibly reaching 30C in London and 25 to 27C further west and north. In the east temperatures will be pegged back to around 16C with a chilly onshore breeze. Storms will develop rapidly from 6pm onwards, continuing into the following day; some of these will be severe with frequent lightning and torrential rain. The exception will again be the east, where low cloud and mist will spread inland"
