The Met Office has said it will be a hot and humid rest of the week, with some areas experiencing their fourth heatwave of the summer.
There is the potential for thundery weather with showers, which could be seen in parts of the country, particularly in the north.
There is a chance for thunderstorms on Wednesday and temperatures could peak to 34C and the heat will move eastwards and Scotland could also see the mercury top 30C.
Met Office Chief Meteorologist Dan Suri said, “Wednesday brings a more complex picture, with high temperatures but also the chance of thunderstorms arriving in the evening.
“During Wednesday daytime, temperatures could peak at 34°C, with the heat shifting eastwards into east England, while parts of Scotland could also see temperatures above 30°C.
“By the evening, there is an increased risk of thunderstorms across northern areas, with the potential for some fairly wet weather.
“Whilst the exact location for these unsettled conditions remains uncertain, it’s possible a warning may be issued closer to the time.”
Thursday will be another widely warm and dry day, with sunny spells for most.
A few showers may develop in the north, which could be heavy and thundery at times, becoming confined to northern Scotland later on. Northern Ireland and the west may also see some showers. Temperatures will likely reach 29-30°C, especially in the far east of England, and staying closer to average in the west.
A north/south split is likely on Friday, with cloudier conditions and some patchy rain or drizzle in parts of the north, but plenty of fine and sunny weather in the south.
Temperatures in that sunshine are likely to peak at 30°C. There is the possibility of a few showers or thunderstorms in the southwest later on Friday and into the weekend.
