Thundery showers and heavy rain will hit London ahead of a sunny 27C heatwave this week, forecasters are predicting.
According to BBC Weather, thunderstorms will sweep over the capital from around 1pm on Monday and into Tuesday.
Thick cloud and heavy rain will sweep in from the west on Monday evening, with Tuesday bringing plenty more blustery showers.
The showers should clear by midday on Tuesday, with some light rain forecast for the afternoon and temperatures hovering around 16C for the most part.
This prediction is echoed by the Met Office which is forecasting rainfall throughout much of Tuesday.
Luckily, temperatures are set to soar and Londoners can look forward to a mini-heatwave across the bank holiday weekend.
The rumours are true, it's warming up as we head towards the Bank Holiday weekend 🌡️

Glorious sunshine and temperatures of 24C will hit the capital from Thursday and climb into the late twenties, reaching highs of 27C on Friday and Saturday., forecasters predict
Sunday is expected to be slightly cooler at 25C, but sunny spells should continue into bank holiday Monday.
Craig Snell, forecaster at the Met Office, said: “The first half of this week is still going to be changeable, if not unsettled, across parts of the UK.
“Temperatures at the start of the week are still a little subdued for the time of the year, as we head towards the weekend we are expecting to see a change.”
He added: “The best of the sunshine across the bank holiday weekend will probably be across England and Wales.”
“Temperatures still above normal, potentially very warm again, but it’s a bit too far in the future to get maximums.
“Indications are at the moment that the bank holiday looks a lot better than what we’ve had over the last week or so.”
Hail and rain swept across the capital last week as the temperature plunged to 12C.
