A brief spell of heat and thunderstorms

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.

    “Persistent rain, locally very heavy, will spread across southwest England and south Wales today, whilst isolated severe thunderstorms may well develop further east bringing the risk of torrential downpours. Rain and showers will spread north through Friday night into Saturday morning, easing with time. Whilst most places will miss the heavier rain, the public should be aware that there is a chance of some very localised significant disruption, mainly from surface water flooding. Lightning and hail could also cause some impacts.
    An area of warm, humid, unstable air will move north across the region today and tonight. Thunderstorms bring the potential for 20 to 30 mm falling within an hour or so, probably on a very localised basis and more likely roughly Dorset and Somerset eastwards to Home Counties. More persistent rain will give 10-20 mm quite widely over southwest England and south Wales with the risk of more than 40 mm locally.”

    Oh dear … well we did see an inch of rain in parts of south west England and a few briefly heavy thundery showers in the evening in parts of Kent, East Anglia and the north and east Midlands. But nothing else approaching us from the south.
