BRITS will see 22 degrees Celsius of sunshine today – before a thunderstorm warning goes into effect tomorrow.
Temperatures are forecast to remain high today, with much of the UK enjoying another warm, sunny day.
The Bureau of Meteorology predicts that temperatures could reach 22 degrees Celsius by 1pm in places as far away as York and Southampton – with peaks of 23 degrees Celsius in Yeovil, Reading, Swindon, Cambridge and London at 4. pm.
But there will be sporadic rain in Northern Ireland and Wales throughout the day – potentially even lightning and heavy hail during short, heavy downpours.
Elsewhere, fine weather will continue, with the sun shining through thin clouds over eastern England and Scotland.
But in rainy Northern Ireland, temperatures can drop to as low as 19 degrees Celsius.
Humidity will make the weather toss and turn on Saturday night – ahead of the Met Office’s yellow warning for heavy rain and thunderstorms on Sunday.
The warning will apply all day Sunday across England and Wales.
Although some areas will be drenched by prolonged thunderstorms, most areas will experience only showers.
But 30mm of rain could fall in just an hour in some parts of the UK, with 60mm in six hours.
There is also the possibility of frequent lightning, strong winds and hail.
Even in the short term, there’s still a lot of uncertainty about where thunderstorms will develop.
The Met Office said: “Heavy rain and thunderstorms on Sunday will present an opportunity for disruption to parts of England and Wales.
“Sudden fog and flooding can lead to difficult driving conditions and some roads being closed.
“There is a small chance that homes and businesses could quickly flood, causing damage to some buildings from floodwaters, lightning strikes, hail or strong winds.
“In places where floods or lightning strikes, train and bus services are likely to be delayed and cancelled.
“There is a small possibility that power cuts could occur and other services for some homes and businesses could be lost.
“There is a small possibility that some communities are divided by flooded roads.”
It comes as Britons are hit by a ban on faucets – after thousands went without water for days amid a heatwave.
