UK weather forecast – Squally showers and storms to plague Britain this week… but blistering 30C Bank Holiday sunshine is on the way

SQUALLY showers and storms will make it a wet start for many today – but blistering 30C Bank Holiday sunshine is on the horizon.

Forecasters say cool temperatures and changeable conditions will give way to warm sunshine to save summer after a miserable August.

But first, Brits will have to endure deluges and thunderstorms – especially in the south and south-east on Monday.

And sudden outbreaks of rain will plague much of the country throughout this week.

Temperatures will struggle to increase above the low 20Cs – but there will be some sunny spells for parts of the south later this week.

Heavier showers are expected across central England and the north will also see longer spells of rain as the week progresses.

The Met Office said: “A breezy day with sunny spells and scattered showers, these heavy and possibly thundery in places, particularly across the south and southeast during the afternoon.

“Driest across eastern Scotland and northeast England with only isolated showers here.

For Monday night, the forecast reads: “Showers dying away for most, although some lingering near northern and western coasts.

“Parts of Northern Ireland, southern Scotland and far northwestern England may also keep showers throughout the night.”

But the mercury will start to creep up again by the end of this week – when southerly winds blow into England and Wales.

A “tropical heat surge” will then rescue summer by August Bank Holiday weekend – with temperatures set to nudge 30C (86F).

Skies will steadily clear from midweek with warmer weather settling in by Friday – cheering Brits up after storm-hit August put this summer on track to be the wettest for seven years.

The Met Office forecasts decent 22C sunny spells for all by Thursday as showers ease in the South and East.

And the mercury is set to hit 25C by the long weekend – with high pressure set to bring subtropical air from the Azores.

The North and West will still see showers at times.

DRY END TO SUMMER

But the Met Office forecasts three weeks of mainly warm and dry conditions for many for the last week of August and first half of September.

Temperatures pushing 30C are forecast by The Weather Outlook and ex-BBC and Met Office forecaster John Hammond of weathertrending.

A total of 272mm of rain fell between June 1 and August 15, Met Office figures show.

With rainfall to add from the second half of August, a total of over 315mm would make this summer the wettest since 2012’s wettest summer for 100 years – when 379mm fell.

High pressure looks like dominating in the last week of August – with mainly settled conditions and the mid-20s possible

Greg DewhurstMet Office forecaster

Met Office forecaster Greg Dewhurst said: “There’s an improvement after wet and windy weather, with plenty of sunny spells through the next week and 25C possible by the Bank Holiday weekend.

“Low pressure clears from Monday and high pressure slowly builds, with a southerly flow possible, with fewer showers in the south and east while the north and west remain less settled.

“High pressure looks like dominating in the last week of August – with mainly settled conditions and the mid-20s possible.”

HIGH PRESSURE

Met Office forecaster Sarah Kent said: “August 31 to September 14 has signs high pressure will increasingly dominate.

“Temperatures are likely to be warmer than average.”

The Weather Outlook forecaster Brian Gaze said: “August has been shocking but summer is poised to be rescued by high pressure pulling up subtropical air from the Azores by the Bank Holiday weekend.

“Highs approaching 30C are expected into September.”

Ex-BBC and Met Office forecaster John Hammond of weathertrending said: “Summer lurched from hot to cool and wet, but warmer weather in time for the Bank Holiday will lift the mood of weather-beaten Brits.

“Temperatures should be not far from 30C for some at the end of August.”
