UK weather: Britain's record-breaking heatwave is about to come to an abrupt, stormy end

Britain has been basking in glorious sunshine for the past few days but it’s all set to come to a crashing halt today.

The record-breaking heatwave – that saw the hottest June day since 1976 – is going to make way for that old summer favourite – rain.

Severe weather warnings are in place overnight and throughout Thursday, with a cold front set to bring heavy rain and thunderstorms to parts of southern Scotland, northern England, north Wales and the Midlands.

And it’s not just a little storm, either – the Met Office warned of the potential for torrential downpours, frequent lightning, very large hailstones and strong gusts of wind, which could lead to localised flooding and temporary disruption of power supplies overnight until early on Thursday.

Heavy showers, which could still involve hail, are likely to push across the southern parts of England as the night progresses, starting with Dorset at around 6am.

They are then predicted to move eastwards, hitting London between 8am -10am, and clearing East Anglia by lunchtime.

Further showers are also likely in Lincolnshire, where the weather warning is in place until 5pm.

Met Office meteorologist Alex Burkhill said: “Once these showers clear away it’s not looking too bad.

“It should be a fairly fine day, cloudier than of late but there will still be some sunshine.”

He added that Thursday will see a “marked drop” in temperatures, with conditions feeling fresher into the afternoon.

In the far south-east corner of the UK, Kent is expected to hold on to the heat for the longest, with maximum temperatures of 27-28C predicted.

Most areas can expect mid – high 20s – which is still pleasant but nowhere near the sweltering 34C reached on Wednesday, the UK’s hottest June day in more than 40 years.

Heathrow in west London had recorded temperatures of 34.5C by 4pm, the highest for June since the 35.6C recorded in Southampton on June 28 1976.

The 40-year high – which is the hottest summer solstice on record – was recorded as parts of Britain sweltered for a fifth consecutive day with temperatures above 30C.

The sweltering temperatures placed “unprecedented demand” on ambulance services in London, with people fainting, collapsing and becoming unconscious in the heat.

On Monday, London Ambulance Service call handlers answered 6,613 emergency calls, compared with 4,695 the week before – a 41% increase – and the service warned this was expected to continue while the heatwave lasted.

Youngsters were urged not to go swimming in lakes, rivers and reservoirs during the hot weather, following the deaths of two teenagers in separate incidents.

A 16-year-old boy died at a reservoir in Rochdale, Greater Manchester, on Monday, while a 15-year-old boy died after going into a lake with friends in the Pelsall area of the Black Country, in the West Midlands, on Tuesday evening.
