Following a hot day, scattered thunderstorms are likely to break out from late Thursday afternoon onwards.
While some areas may well avoid the storms, where they do occur they could produce 20-30 mm of rain in less than an hour, along with frequent lightning, hail and gusty winds.
Perhaps the main focus will be later in the evening and into the first part of the night across northern England and southern and eastern parts of Scotland, where storms could be more widespread and locally intense.
