Temperatures are expected to hit 30C today, making it the hottest day of the year so far.
But there’s still a way to go before we reach the highest temperature recorded in the East Midlands.

The warm temperatures are expected to last throughout the week, though spells of rain are likely.
A yellow be aware alert of rain has been issed for Derbyshire between 4pm and 11.50pm today with thunderstorms expected.
