The UK is set for a day of heavy showers and thunder as a new weather front brings plenty of clouds overshadowing most of the country today.
BBC Weather forecaster Carol Kirkwood warned rain could be so heavy and slow moving it could cause flash flooding in some parts of the UK.
The BBC forecaster said: “For much of the UK today, it is a cloudy start to the day but sunny spells will develop.
“But there are showers in the forecast today, we’ve got some already and we’re likely to see more developed through the day which could be heavy, thundery and slow-moving and could lead to some flash flooding.
“So this morning at 9am across Scotland a lot of clouds, rain on and off through the day across the far north.
“It’s very patchy. Some brother skies down towards the south-west and later it will brighten up across the north-west of Scotland as well.
“For Northern Ireland, you too have a cloudy start. Some brighter spells developing across eastern Northern Ireland through the day.
“North-west England some brighter spells for you too but in eastern England, we’ve got quite a bit of cloud.
“All the way south, down towards Kent and down towards Hampshire.
“There are some brighter skies this morning but we’ve also got those showers for parts of Wales, the West Midlands, we’ll see some across north-west England later.
“The Channel Islands though will see a beautiful start to the day and you’ll hang on to a fair bit of sunshine through the day.”
BBC Weather forecaster Ben Rich also said the rain will start in the UK today.
He said: “We go on into tomorrow – a lot of cloud again across Scotland. The odd splash of rain with this.
“A fair amount of cloud for Northern Ireland as well. For southern Scotland down into England and Wales, where we will see some spells of sunshine.
“We are also going to see one or two scattered showers in western areas – quite hit and miss but some of these could well be on the heavy side.
“Temperatures during Thursday between 21 and 26C.”
The BBC Weather forecaster warned there will be more heavy rainfall into Friday.
Mr Rich said: “There will be more showers by this stage. Still hit and miss – not everyone will see one.
“But some heavy thundery downpours developing here and there. Some spells of sunshine as well. And those temperatures generally between about 20 and 26C.”
The Met Office has issued its first lightning storm alert for Wales in 164 years.
The Met Office yellow weather warning says the torrential weather will hit from 11am on Friday until 8pm that evening.
The Met Office warning states: “Heavy showers, which will most likely become thundery in places, are expected to develop quite widely across parts of England and Wales later Friday morning and through the afternoon.
“Some of the showers are likely to become focused into slow-moving bands, particularly over southwest England, with some locations receiving around 20mm in an hour.
“As is the nature of showers, however, many places within the warning area will miss them altogether, and have a dry day.”
