South east London and north Kent will face chilly temperatures this week, thanks to a blast of Arctic air.

Despite the approach of May, forecasters say that summer will feel a long way off.

Temperatures will struggle into double figures in the south of the country, but many areas will see highs of just 7 degrees - about 4 degrees below the average for this time of year.

Global temperature records were broken in January, February and March, Nasa announced last week, but the UK is unlikely to feel the benefit of this trend this week.

The Met Office predicts frequent showers which will mainly fall as rain but Scotland and parts of northern England - especially on high ground - may see snow.

Overnight it will be cold enough for a frost.

Met Office forecaster Emma Boorman said: "It's going to be cold this week, particularly at the start of the week.

"Winds are coming from the north. The originated in the Arctic and that's why it is colder than we normally expect it to be at this time of year.

"In the south it will be mixture of sunshine and showers but further north these showers will turn increasingly wintry - that's a mixture of rain, some sleet and some snow."
