UK weather forecast – Four days of downpours on the way as 800-mile wide Atlantic storm threatens flood warnings this week

FOUR days of washouts from an 800-mile wide Atlantic storm front will hit this week, forecasters say.

The Met Office is preparing severe weather warnings from Wednesday – with soakings in many areas set to last until at least Saturday.

Over an inch of rain is expected in intense showers in parts – with daily thunderstorms expected across the country.

And today will be another disappointing day in terms of temperatures – with lows of -5C first thing in the morning.

Snow is due today and tomorrow night in the North on high ground, and on Thursday on north Wales' mountains.

Gusts up to 45mph will buffet South, West and East coasts and highs will be just 11-15C.

It comes after disappointed Brits quit beach resorts early as Bank Holiday Monday was colder than Siberia – and verged on the coldest ever.

A 2,000-mile wide North Pole 'polar plunge' chill made yesterday verge on the record for the coldest early May Bank Holiday since the holiday began 41 years ago in 1978.

There were highs of just 12C at 12 noon and -4.0C at Katesbridge, Northern Ireland, yesterday morning was close to the -5.9C record set in 2012.

It meant Britain was colder than -3C lows in Yakutsk, the world’s coldest city, in eastern Siberia – and -1C lows in Tasiilaq, Greenland.

And the UK was 15C colder than a year ago – when the early May Bank Holiday saw a record 28.7C at Northolt, London.

The jet stream will bring low pressure across the country, with a warning likely on Wednesday night for surface water flooding in eastern Scotland

Met Office forecaster Emma Smith said: “Monday was close to the coldest May Bank Holiday minimum temperature on record, and Tuesday morning could be colder at -5C in Scotland.

“Now the jet stream will bring low pressure across the country, with a warning likely on Wednesday night for surface water flooding in eastern Scotland.

“A big band of rain will move across the country on Wednesday, with 15-20mm widely and 30mm in the North-East of the UK.

“Thunderstorms follow the rain on Wednesday and are expected until Friday, with the Midlands and South most affected and the North at risk on Friday.

"Outbreaks of rain continue on Saturday.

SNOW AND SLEET

“Snow and sleet could be seen in the North and southern Scotland over 400m into Tuesday and on Wednesday night, and in Snowdonia on Thursday.

“It will be windy in parts from Wednesday until Saturday, with maybe the odd 45mph gust and 40mph gusts generally on coasts in the South-West, South and East.

“Highs will be around 11-15C.”

Met Office forecaster Steven Keates said: “The coldest air coming to Britain is from north of Russia, converging with cold air from well north of the Arctic Circle, not too far from the Pole, and flooding to the UK and a good part of Europe as far south as Italy.

“Unseasonal snow in the second week of May is expected on Scottish mountains, with disappointing temperatures.

“This is not at all like how early May should feel – and blowy conditions are ahead.
