UK weather forecast: Temperatures to plunge by nearly 20C with three-day washout coming

Brits are being warned to brace for a near-20C plummet in temperature as the UK faces a three day washout and "unseasonably" strong winds.

The recent heatwave has seen the mercury soar to nearly 30C in parts of England but experts say it's set to drop into single figures as a new front moves in.

The enormous cyclone, three times the size of the UK will unleash heavy downpours, gusts and threats of thunder.

It stretches from Scandinavia to the west coast of Spain and is expected to target the northwest, western Scotland and Wales the hardest.

Met Office meteorologist Alex Deakin said: “After the heat and humidity, it’s all change into the weekend with low pressure the dominant feature.

“That low pressure system isn’t moving too far and with its isobars fairly tightly packed, it will bring some fairly gusty conditions increasingly to western Scotland, and it will be unseasonably windy in the northwest.

“Then it’s a case of watching the showers develop, the closer you are to that low pressure system the more showers you are likely to see.

“There will be plenty of them across Wales western England and southwest Scotland.”

The cooling blast is set to send Brits crashing back to reality after a fortnight of basking in glorious sunshine.

Mr Deakin continued: “A cold front will sweep away all that warmth and humidity and introduce much fresher air as it wanders across the country into Saturday.

“That cooler air will be in place through Saturday and lasting into Sunday.

“It is turning fresher but there will be plenty of showers around this weekend.”

He added: “With that low in place, it will be very gusty and unseasonably windy for the time of year.”

The warnings also come with a threat of thunderstorms as the wet weather drags on after the weekend.

The southeast and eastern regions may escape somewhat unscathed with slightly warmer temperatures in the the low 20Cs.

Jim Dale, meteorologist for British Weather Services, said: “A low-pressure system in the Atlantic will push fresher winds into western parts of the country.

“We will be chasing showers, and there might be the odd heavier one with a rumble of thunder.

“There will be fewer showers on Sunday, and then on Saturday they will start to pick up again on Monday.”

But the forecast has prompted fears for a wet Wimbledon as tennis fans are warned to pack a waterproof or brolly.

John Hammond, meteorologist for Weathertrending, said: “Wimbledon arrives under the watchful eye of a slow-moving area of low pressure sitting on our doorstep.

“For much of the week ahead, that same low-pressure area will ensure a showery outlook.

“Furthest from the low pressure’s centre, some eastern areas of the country look set to see the best of some lengthier drier, brighter spells, especially early in the week.”

Exacta Weather’s James Madden added: “We expect to see a return to more normal temperatures and a littering of thunderstorm activity."
