UK weather forecast: Atlantic blast brings snow showers to Britain in ‘rollercoaster’ week

The Met Office has issued a yellow weather warning for Tuesday and Wednesday. The warning of heavy rain covers areas in Scotland where rainfall could reach 150-200mm in a few locations.

The Met Office said: “Rain will persist throughout Tuesday and into Wednesday, turning heavy at times, with heaviest rainfall over high ground.

“By Wednesday afternoon 50-100 mm of rain will fall widely with 150-200 mm possible in a few locations over high ground.”

Met Office meteorologist, Tom Morgan, said: “It’s going to be a bit of a rollercoaster [this] week with a spell of unsettled weather on the way.

“It will be fairly mild on Monday to Wednesday, especially in the southern regions, and will be a lot brighter and drier than what we’ve seen across the weekend, though rain will still come and go.

“It’s a different story for the rest of the UK, which will be considerably colder and wetter, with up to 150mm of rainfall expected in mountainous regions of Northern Ireland, Scotland and northern England.”

Snow showers are forecast to sweep in from as early as Thursday morning due to a brisk cold air.

But before temperatures plummet, Tuesday is set to start off as a fairly mild day with blustery winds.

Temperatures will reach 14-15C is most places and could jump up to 17C in the south west of the country.

Alex Deakin, Met Office Meteorologist, said: “Temperatures are going to be up and down this week. It is going to be very mild on Tuesday.”

He added: “As well as being mild for some, it’s going to be very soggy through Tuesday and Wednesday.

“We’re particularly concerned about western Scotland where the rain will be heavy and could cause some problems.”

The Met Office have said that some transport services will be affected “with journey times taking longer”.

It added: “There is a small chance that some communities become cut off by flooded roads.”

Mr Deakin said temperatures are “really dropping off” through Wednesday night and Thursday with significant “wind chill”.

The change in weather is thanks to “vigorous” low pressure which will sweep in midway through the week.

Jo Farrow, Netweather forecaster, said: “Significant changes come as a vigorous midweek low pressure moves through and colder air follows.

“The cold front sweeps over Britain on Wednesday, and through Wednesday night a raging northerly takes hold briefly for northern Britain, Northern Ireland and will bring snow showers for Thursday morning with a wintry start the day. Much different from Tuesday’s warmth.”

The cold front will bring much cooler conditions on Wednesday followed by a blast of even colder air will hit the UK.

Mr Deakin said: “Much, much colder air coming right down from the north streams in accompanied by some gusty winds to start with on Thursday.

“That’s going to be a bit of a shock to the system and it will feel so much colder with those brisk and chilly winds.”

Widespread frost across the UK is forecast for Thursday as the country braces for a wintry end to the week.
