Met Office forecasters have issued yellow weather warnings for thunderstorms spanning three days, and have now brought forward Friday’s warning. Now the warning is in effect from 6am, three hours earlier than the original 9am warning. Here are the latest updates.
The warning area covers the East Midlands, East of England, London and South East England, South West England, West Midlands and Yorkshire and Humber.
Starting at 6am on Friday, the warning is in place until 6am on Saturday morning.
The Met Office warns: “A spell of quite prolonged and often heavy rain is expected to spread northwards into parts of England on Friday though there remains uncertainty in how far northwest this progresses.
“This area of rain then clears away northeast on Saturday morning. Parts of East Anglia, the East Midlands and southeast England may see 20 to 40 mm of rain with a few sites potentially seeing 50 to 70 mm.

“However, many parts will see much less rainfall. Some thunder and lightning is also possible, particularly in East Anglia, the East Midlands and southeast England but heavy rain is the main hazard.”
Netweather warns these heavy, thundery downpours will spin off the low pressure and bring the threat of torrential downpours.
Throughout Friday, these downpours will head northwards however there is some uncertainty of how far west they will travel.
Already torrential rain has lashed the south of England, with flash flooding in Kent on Wednesday night.
The Met Office tweeted: “There have been some heavy, #thundery downpours across parts of SE England overnight.
“There’s a risk of some further spells of heavy rain as an area of thundery showers looks set to clip SE England this morning. Take care if you’re planning to travel.”
Netweather forecasters say today’s weather “depends on cloud breaks”.
In their latest forecast the experts write: “Temperatures across the UK will be in the high teens to low twenties Celsius with fresher, cooler air edging over more of Britain behind a weak cold front.
“Ahead of this, for SE England and East Anglia, in any sunshine, the temperatures will leap up to around 27C.
“This extra energy combined with high dew point air, large CAPE and signs of breeze convergence this afternoon brings the risk of isolated surface-based thunderstorms brewing up.”
