The Met Office has warned that lightning and hail could be widespread as the storm moves northwards.
More rain is set to arrive on Friday evening in London, with heavier downpours forecast in Wales, the north of England and Scotland.
On Saturday, temperatures will stay in the low 20C across England and Wales. But heavy downpours are also expected to sweep east across the country.
