Forecasters at BBC Weather are predicting thundery showers all of Thursday morning, with the potential of thunder and lightning between 11am and 1pm.
There is also a chance of thunderstorms again between 3pm and 7pm on Thursday afternoon ahead of a drizzly and wet night with more light rain showers.
Friday promises to be drier and clearer with plenty of sunny intervals throughout the day.
However, thunderstorms are set to return across bank holiday weekend with potential storms set to hit the capital on Saturday and Sunday.
The wet weather comes after one of London’s driest summers on record and the spate of showers could provide some much-needed reprieve for Londoners.
There was no meaningful rain in July in London, with zero rain measured in parts of north London and just 1mm in areas south of the river.
The capital’s green spaces have been scorched by the blistering heat, turning from bright green to straw-coloured and becoming hotbed for wildfires in a matter of months.
Millions have also been placed under hosepipe bans as London ploughs through drought conditions.
Met Office Chief Forecaster Steve Willington said: “On Thursday, slow-moving heavy and thundery rain may bring prolonged rainfall to some areas, increasing the risk of localised impacts. There remains some uncertainty around where the heaviest rain will fall, so it is important to keep up to date with the latest forecast and warnings"
