High pressure to hit Britain with entire week of ‘prolonged sunshine’ and warm temperatures

Saturday’s forecast suggests temperatures will hover around the low teens.

Cardiff and Glasgow could see mercury hit 12C.

Belfast might even witness temperatures reach 14C the following day.

The switch comes just days after a yellow wind warning was issued across much of Great Britain.

Looking ahead to Saturday, the Met Office said: “Finally on Saturday, some much awaited high pressure moves in from the Atlantic.

“It’s a cold start though, with the possibility of some frost, especially in the north. Light winds and sunshine will make the day feel rather pleasant for many, even if temperatures don’t read very high, mid-teens at best.

LATEST DEVELOPMENTS:

“The southwest is likely to see the most prolonged sunshine.

“There is some cloud and rain expected in the far north of Scotland and Northern Ireland, but for most, it’s a fine and dry day.

“Cold overnight with a frost most likely in southern areas.

“High pressure is still in place on Sunday, although showers are possible in some northerly and eastern areas.

“Probably cloudier overall than Saturday, especially in the north and east but still enjoying some sunny spells too.

“That milder air spreads across the UK, with temperatures up a touch compared to Saturday.”

Deputy Chief Meteorologist Mark Sidaway added: “Don’t expect a heatwave. Temperatures will be close, or a little above average but feeling warm in the sunshine and light winds.

“The high will also bring with it a good deal of dry weather for most of the country, although some northern and perhaps eastern areas will see a little rain at times.”

However, the UK’s national weather service was keen to stress mercury will likely drop as the UK looks even further ahead.
