The Met Office has issued a yellow weather warning for thunderstorms across Nottinghamshire and most of the UK.
A warning has been put in place from 12pm Wednesday, June 17, and the bad weather is expected to last for 12 hours.
Although some places will remain dry, slow moving heavy showers and thunderstorms may lead to disruption due to flooding, the Met Office warned.
A second yellow weather warning for rain on Thursday across Nottinghamshire has also been issued.
That warning is in place from 3am to 12pm on June 18.
In Nottingham there is a 50 to 60 percent chance of thunderstorms between 2pm and 4pm on Wednesday, according to forecasters.
