Southern parts of the UK can expect some very warm and humid conditions on Friday, along with an increasing risk of some heavy, thundery showers.
Isolated thunderstorms are possible from Thursday, but they will become more likely and potentially more severe by Friday afternoon, with some locally torrential downpours possible, especially for parts of southeast England. A yellow warning has been issued for heavy rain. There is the potential for large amounts of rain is a short space of time, and this could lead to surface water flooding, but as is the case with showers, some places will stay dry. We are also likely to see frequent lightning, and hail is possible in places – as we saw last Friday.
Away from the south, there will be sunshine for many, though it will be cloudier with a little light rain in the far north.
Into the weekend, temperatures will take a tumble across much of the country. Saturday will see a band of rain across central areas, with occasional brighter spells either side. The rain will become increasingly light and patchy by Sunday with drier conditions developing for many. It will feel noticeably cooler though, with the return of some chilly nights.
With many people out and about at this time of year including at the Isle of Wight and Download festivals, we should be prepared for all types of weather over the next few days, from humid to cool and from rain to shine.
