UK weather forecast: ‘Hot Mediterranean air’ hits as heatwave to return -Long-range charts

Britain basked in glorious sunshine last month with May becoming the sunniest calendar month on record, according to the Met Office. Temperatures soared into the high 20C’s for much of the country, as Britons rushed to parks and beaches to soak up the sunshine – while abiding by strict social distancing guidelines due to the ongoing coronavirus pandemic. But, the start of June has seen temperatures plummet by as much as 10C in some parts, with scattered showers bringing heavy downpours for some regions.

The unsettled conditions are expected to continue well into next week, forecasters claim – bringing an abrupt end to the heatwave.

Over the next few days, BBC Weather warns the “UK will see a pattern shift that will bring some very different weather”.

But, looking further ahead, BBC Weather predicts the return of “mostly dry and warm” weather between Monday, June 15, and Sunday, June 28.

The long-range forecast from BBC Weather claimed “similar weather to that just seen through May” could return – potentially bringing another heatwave to the UK’s shores.

But they added there was also a risk of “hot Mediterranean air” heading towards Britain – in turn bringing “some thundery downpours”.

The forecast read: “Once the high-pressure ridge builds in from the Atlantic, it is likely to stick around for most of the rest of June and give us some similar weather to that just seen through May.

“Most of the UK will be sunny, warmer than normal, and dry for much of the second half of June.”

But, BBC Weather did note they expect June to be “a slightly more changeable month than May or April” which would bring some “brief wet, cool spells” – adding “although these should last for more than a day or two”.

The forecast suggested Scotland would be the main exception and “may well see more frequent outbreaks of rain from weak fronts”.

In their long-range outlook, BBC Weather also instead warned of a risk of high-pressure building “strongly to our north and northwest, perhaps near Greenland and Iceland like it is doing at the moment”.

They claimed this would “let low-pressure systems near Spain and Portugal move into the UK from the south and bring some thundery downpours”.

BBC Weather said: “This would, however, also bring in some hot Mediterranean air, so it would still be a warmer than normal pattern.

“As such, confidence is a bit higher for a warmer than normal June, but low on the dryness and sunshine.”

Looking towards the next few days this week, BBC Weather said: “By Friday and into the weekend, however, the cold front will sweep into Central Europe and bring cooler, windier weather for the whole country.

“Some strong wind gusts are possible on northern and western coasts. Low pressure in the North Sea is likely to drift nearer on Saturday and Sunday, bringing some much wetter weather.

“After a warm, sunny, and dry week for most of the country, Saturday will be quite a change with a windy, wet, and cool day.”

It comes after May went down as the sunniest Spring on record for the UK and all the home nations and the driest May on record in England, according to the Met Office.

Dr Mark McCarthy, the head of the Met Office’s National Climate Information Centre, said: “The most remarkable aspect is just how much some of the May and Spring records for these climate statistics have been exceeded.

“Exceeding the UK sunshine record is one thing, but exceeding by over 70 hours is truly exceptional.”

He added the “sunshine figures for spring would even be extremely unusual for summer” and only three summers would top Spring 2020 for sunshine hours.

Dr McCarthy also explained the reasoning behind the dry and sunny weather for the lengthy period across the UK.

He said: “The principal reason for the dry and sunny weather is the extended period of high pressure which has been centred over or close to the UK.

“This has suppressed the development of clouds and rainfall over the UK, while allowing plenty of sunshine to reach the surface.

“There has been a band of similar weather conditions extending across central parts of Europe, whereas Iberia and parts of Scandinavia have experienced rather wetter conditions.”
