This weekend looks like being very warm for most of us. Highest temperatures of 23 or 26C are likely to be in the Midlands, East Anglia and south-east England on Sunday.
And while the sunny weather will continue for many, on Saturday night the weather will start to change.
There is an increasing chance of rain and thunderstorms moving across south-western parts of the UK. These will continue on Sunday and could spread to Northern Ireland.
Heavy downpours and storms could continue across southern and western parts of the UK into Monday.
There is still uncertainty regarding the extent of rain and forecasting where thunderstorms will occur. Keep up to date on the BBC Weather app.
And there will be many parts of England and Scotland that will miss the rain completely.
