The rain will continue into Sunday with showers in the north and west, though the weather will be fine and dry across the rest of the UK. Maximums around average for the time of year with maximums of 18-20C in the south and 14-15C in the north.
A spokesman for the Met Office told Huffington Post UK: "After a warm day with thundery showers in the southeast on Friday there will be plenty of sunshine for many over the weekend although it will feel fresher."
