There is a risk of heavy, thundery showers throughout today (Friday) and tomorrow (Saturday, August 10), with high temperatures of 26C.
The Met Office forecast for Friday and Saturday said: "Rain and strong winds clearing north through the morning, leaving a muggy day with sunny spells.
"However, heavy showers with a risk of hail or thunder will develop in the afternoon, with strengthening winds returning. Maximum temperature 26C.
"Heavy or thundery showers tonight, merging at times into longer spells of rain, will persist through much of the night. Turning windy especially over the hills. Minimum temperature 15C.
"On Saturday frequent showers are expected, heavy at times. Windy with gales over the Derbyshire hills and more widely by the afternoon. Perhaps turning drier further east later. Maximum temperature 21C."
