Hot and sunny across England and Wales. Cloud building up a little in the afternoon for some, and low risk of an isolated shower breaking out toward evening. Remnants of a front across Scotland and Ireland leaves a legacy of cloud, but should break in places to give hazy sun. Chance of local bursts of rain in the Scottish Highlands. Temperatures reaching 25 to 30C, hottest around London.
Most places dry overnight with skies fairly clear. Some local mist or low cloud around hills and coasts in eastern Scotland. Light winds inland. A general east to southeasterly breeze prevails around coasts in the south and east. A warm and humid night, with city temperatures on falling to around 18C, whilst rural locations will be typically 13 to 15C by dawn. Cooler in northwest Scotland.
High pressure to the east of Britain promotes a very warm and humid southeasterly airflow, but there will be a breeze for most places. Many places dry all day with lots of sunshine. Some hazy high cloud. A risk of localised showers breaking out in Scotland. Temperatures rising to 25 to 30C, highest temperatures in central-southern England. Much cooler around North Sea coasts with an onshore wind.
Unstable air spreads up from the south. Bursts of rain will move north from Biscay and France into Britain and Ireland. These may be very hit and miss, but bring an increasing risk of thunderstorms developing, particularly afternoon into evening, tracking northeastwards with time. Ahead of this, another hot and humid feeling day, with highs of 24 to 29C, warmest in central-eastern England.
