After Saturday's 77F sizzler temperatures plummet  due to Arctic winds

Well that didn’t last long! After Saturday’s 77F sizzler, temperatures plummet… and winds from Greenland could even bring frost and SNOW this week

  • Temperatures set to plummet further as Arctic blast rushes in from Greenland from Monday onward
  • Glorious heat of Saturday, which reached 24.9C (76.8F) in north London to be replaced with frost and showers
  • London is expected to reach just 54F (12C) Monday after weekend sunshine saw many punters out and about

Just 24 hours earlier Britain had been basking in balmy sunshine that would have put the Med in the shade.

But yesterday temperatures plummeted as an Arctic blast rushed in – and they are set to fall even further today.

The glorious heat will be replaced with frost and even wintry showers in parts of the country.

The mercury peaked at 24.9C (76.8F) at Northolt, in north-west London, on Saturday as most areas enjoyed fine conditions and temperatures in the 70s Fahrenheit.

But London is expected to reach just 12C (54F) today, and temperatures will struggle out of single figures further north, with 9C (48F) forecast in Newcastle-upon-Tyne.

The change is due to a shift in the position of an area of high pressure, which has been dominating the country’s weather and bringing mostly settled conditions. A southerly flow of air from France and Spain has been replaced with winds coming from Greenland.

A cold front brought the chilly weather south through yesterday, with snow showers falling on Scottish mountains. Last night, frost was expected in rural areas and wintry showers as far south as Northumberland and the North York Moors.

Some areas could again be below freezing tonight with temperatures set to fall as low as -2C (28F) even in southern England.

The best of any sunshine today is expected in the South West, while more cloud is expected elsewhere. Blustery winds are expe-cted in eastern and south-eastern areas, reaching 20mph inland, and as strong as 50mph in exposed coastal locations.

Later in the week, the weather is set to be a mixture of cloud and sunny spells, with a chance of showers in the East, and temperatures are expected to rise towards the mid-teens Celsius (mid-50s Fahrenheit).

Met Office spokesman Steven Keates said: ‘The cooler conditions are a bit of a shock to the system. The last few days saw increasingly warm temperatures but a cold front moving south has brought markedly different conditions. For some places there will be a drop in temperature of 8C to 12C.’

It is expected to feel even chillier in places affected by the strong winds. Mr Keates said that although temperatures are set to recover towards the seasonal average by the middle of the week, overnight frosts remain possible.

But, despite the cooler temperatures, there remains a risk of sunburn during breaks in the cloud.

The chillier conditions come after thunderstorms brought flooding, as much as an inch of rain in a couple of hours during the warm weather on Saturday afternoon.

Residents in parts of South and West Wales said heavy rain was turning roads into rivers. The deluge left four homes under water in Carmarthen and also caused flash flooding in Swansea.

Andy Joyce, who runs an electrical shop in Carmarthen, told the BBC: ‘I have been here for 23 years and I’ve never seen this happen before. It was coming down like waves. The next thing it started coming through the basement from underneath the floor.’
