Arctic blast triggers sharp drop in temperatures with lows of 3C, thunderstorms and 50mph icy winds

The glorious bank holiday weather has come to a frosty end with temperatures plummeting by 12 degrees and 50mph icy winds battering parts of the country.

In what is expected to be the hottest day of the year, Saturday brought temperatures of 26C (78.8F) causing many Britons to break coronavirus lockdown rules by flocking to parks in droves.

But barbecues should be swiftly packed away as an Arctic blast sweeps the nation today causing temperatures to plunge by eight to 12 degrees with up to 50mph gusts expected in the most exposed areas.

In stark contrast to this, the south of England is still basking in glorious sunshine with Londoners pictured using parks and outdoor spaces to enjoy the warm weather before the cold front moves in.

‘There is some exceptionally cold air for the time of year. In northern Scotland for example today, temperatures wont get much higher than three or four degrees (37.4 to 39.2F).

‘The far south is relatively warm with temperatures of 20C (68F). But we are looking at temperatures of 12 or 13 (53.6F – 55.4F) degrees in the next few days.

‘It is going to feel particularly cold out there but this is all offset by May sunshine.’

Scotland and eastern England can expect wintry showers as the day goes on, but patches of rain should clear up across the south of the UK. 

Monday will bring chilly winds to much of the UK, with northern Scotland and the eastern side of England seeing showers while frosty nights potentially continuing for much of the rest of the week.

The cooler weather comes ahead of Boris Johnson’s address to the nation at 7pm in which he is expected to relax some of the stricter lockdown measures.

A DefCon-style five stage system will be introduced to describe the country’s outbreak condition, with the UK currently being at the second most serious rating of four – meaning most of the lockdown must be maintained.

With evidence increasingly suggesting the virus spreads far less readily in the open air, the once-a-day limit on outdoor exercise will be dropped.

The focus will also shift to getting businesses up and running where possible, with detailed guidance for firms on how they should operate, and garden centres allowed to open from Wednesday where two-metre ‘social distancing’ rules can be put in place. 

Travellers and shoppers could be urged to wear face coverings, as has already happened in Scotland.

Breaches of the more nuanced rules could be enforced with harsher fines, amid complaints from police that the enforcement so far has been ‘wishy washy’. 

Plans are being drawn up to use ‘peer pressure’ to get people to self-isolate, as those who test positive will be told to get in touch with anyone they might have infected.
