Scattered showers are sweeping the UK on today but skies are set to clear in time for England's semi-final clash with Denmark tonight before Brits are set to enjoy a new heatwave.
Met Office meteorologists have predicted grey skies and rain across the entire nation throughout the day, but said sunshine could break through the clouds in time for the 8pm kick off.
Forecaster Annie Shuttleworth said the heaviest showers are likely to settle in the north-east and south-western corners of England on Wednesday.
She added that up to 50mm of rain has been predicted for the worst-hit region of North Yorkshire.
Ms Shuttleworth said: "It's quite a messy picture - there's a lot of rain going on.
"We are seeing generally unsettled conditions across the whole of the UK with heavy showers in the South and South East.
"On Wednesday morning we will see clouds break out and heavy showers, many across the South East through the mid-morning onwards.
"By early evening showers will start to die away.
"The sunnier and drier spells will be much more likely by 8pm - though there is still a risk of rain."
Four flood alerts, for areas where flooding is possible, have been issued for isolated spots in Hampshire, Berkshire, and Shrewsbury by the Environment Agency.
The Scottish Environment Protection Agency (SEPA) has also issued alerts for areas where rain could cause travel disruption for Dundee and Angus, Fife, Findhorn Nairn Moray and Speyside, and Tayside.
Wednesday highs of 20C are predicted in London, Edinburgh, Cardiff and Belfast.
The outlook for the rest of the week looks much better for the UK.
The Met Office says Thursday will be "a warmer day for most with sunny spells and fewer showers, although some may be quite heavy in the south and east".
And the outlook for Friday to Sunday should be "sunny spells and showers for Friday, though many areas dry."
But if England make it to Sunday night's final heavy and thundery showers are expected in places.
It comes as the UK is predicted to finally warm up with a heatwave coming in the second half of July caused by a hot plume of air banishing the downpours.
According to the Met Office, a "hot spell" of weather is expected to hit England from July 19 and last until August 2.
