UK weather forecast – Mercury to plummet by 20 DEGREES today as Britain takes drenching after record 38.7C heatwave

BRITAIN will take a drenching today following the record 38.7C heatwave – as the mercury plummets by 20 DEGREES in parts.

Thermometers will struggle to hit highs in the low-twenties on Saturday – with most parts only reaching just 18C this afternoon.

And the Greet Cooldown will also be helped along by a soaking – with cold showers across Scotland and much of England today.

But there are fears that up to 100mm of rain could fall in some places – leading to flash floods and travel chaos.

The Met Office issued a yellow weather warning for nearly all of England, Scotland and Northern Ireland to last until 3pm on Sunday.

And a separate weather warning was issued for heavy rain in London and the South East for this morning.


A statement read: “Persistent, heavy rain across this area will continue for the next few hours, leading to some early morning travel disruption.”

Some more dramatic thunderstorms are also expected in parts after days of dramatic lightening sparked by the searing hot conditions.

But it will be nowhere near as stifling – with forecasters expecting highs of just 22C in the far South of England.

Elsewhere, 1pm highs will slowly climb to just 18C – more than 20C below Thursday’s exceptional top temperature.

If the 38.7C temperature reading is verified, that would make yesterday’s scorching weather the hottest ever recorded in Britain.

That was recorded in Cambridge on Thursday  – topping the previous record of 38.5C measured in Faversham, Kent, in 2003.

Locals in Cambridge yesterday likened the suffocating conditions to the Death Valley desert and the Sahara.

Local David Cambridge said: “Standing in the centre yesterday and you closed your eyes you could have easily imagined you had been transported to North Africa.

“The nearest I have come to feeling the sort of heat we had here was driving in Death Valley in 1981!”


But Saturday’s weather is taking a colder and drearier turn – with cloud and rain for many punctuated by brief spells of warm sunshine.

The Met Office forecast said: “Southern and western Scotland, along with northern, central and southeastern parts of England will be rather cloudy with outbreaks of rain, some heavy and thundery.

“Elsewhere it will be mostly dry with some reasonably warm sunshine.”

For tonight, the forecast added: “Overnight, rain is likely to continue affecting southwest Scotland, parts of northern and central England, along with East Anglia, edging slowly into Northern Ireland too.

“Dry elsewhere with clear spells.”

Weather experts at Meteogroup UK also painted a dull picture for Saturday.

Their forecast read: “It will be cloudy with rain across Scotland, northern England, eastern England and parts of East Anglia and south-east England.

“Some embedded thunderstorms are possible at times, especially along eastern coasts.

“It will be dry with sunny spells in the south and west. Gentle and variable winds.”
