Flood risk warning as more downpours are forecast
Heavy showers look set to return for parts of the country after days of sporadic deluges triggered flash flooding.
North Wales, the north west of England, Northern Ireland and Western Scotland could see isolated downpours dumping over a week of rain in an hour on Thursday, bringing a risk of localised flooding.
Elsewhere conditions are set to be warm and sunny, although eastern parts will have to wait for fog to burn off during the morning.
Met Office forecaster Sophie Yeomans said: "The biggest risk of showers will be in those western areas where they may be quite heavy, although not as bad as we had seen in recent days."
It was a mixed picture for Britons on Wednesday, as tourists in Cambridge were pictured enjoying a sunny punt ride along the river Cam, while torrential rain and thundery showers lashed other parts of the country.
In the capital and parts of the Midlands, flash downpours left people drenched, and images shared on social media showed roads partially flooded.
Londoners were caught in sudden downpours for the second consecutive day, with torrential rain hitting the capital in the early afternoon.
On Tuesday, flash floods caused three cars to be submerged, and their drivers had to be rescued, in Croydon, south London.
While the last remnants of the wet and humid weather clear over the UK on Thursday up to 20mm of rain could fall in isolated downpours over western parts, a third of the monthly average of 60mm.
Temperatures are expected to climb up to 25C [77F] in the south east during the day, while most of the country will see the mercury rise over 20C [68F].
Some cloud will persist, although sunny spells are expected for most.
As the weekend approaches temperatures are expected to fall away, although the muggy conditions seen during the week will clear.
