The UK is set for its warmest day of the year so far today, with temperatures to soar north of 20C in London.
Large parts of south and east England and Wales are in for a fine weekend, with the mercury possibly set to beat the 20.9C record set last Saturday.
Forecasters said the bright spell was a result of warmer air across the country and an area of high pressure just south of Britain.
While wetter conditions have hit northern England and Scotland this morning, warmer and drier weather is on the way with thermometers reaching 17C in north east England on Saturday.
Some showers will persist however in Northern Ireland and Scotland on Saturday, with the potential for some 'localised issues', while north west England could be hit by strong gusty winds.
On Thursday Britons enjoyed the first of what could be three consecutive days of 20C heat with a splash in the sea, despite sea temperatures of just 7C.

The Met Office said that temperatures will feel closer to the April average by Sunday, however, with most areas feeling notably cooler from around 10C to 15C.
Metereologist Alex Burkill said that the south east and London would get a 'decent amount of sunshine' on Saturday.

'Next week does get off to a showery start for many of us and it is going to be fresher than through Friday and Saturday in particular.'
But looking further ahead, Britain may be in for its most 'prolonged dry spell than we have seen for many weeks or months' with some 'promising signs' of low pressure building from the west.
