Soaring temperatures and thunderstorms are on the cards for west London as a "Spanish Plume" hits the UK.
Temperatures could hit 30 C again , as an area of high pressure coming from the continent brings the heat with it.
It's expected to stay dry, sunny and warm throughout the day on Monday (July 17) with a clear night.
However, this spout of hot weather means there is a higher risk of storms, heavy rain and hail.
A yellow weather warning has been issued for London and other parts of the South East on Tuesday (July 18) and Wednesday (July 19).
But the Met Office has stated some places will miss the rain altogether.
Tuesday (July 18) is expected to be another hot one with scattered thundery showers in the evening, continuing into a hot and humid Wednesday (July 19).
Thursday (July 20) should be mainly dry and bright as Friday (July 21) sees cloud, rain and possible showers.
This random weather pattern is all because of the Spanish Plume phenomenon, which is when hot air from the continent moves north and causes thunderstorms.
A Met Office spokeswoman told Hull Daily Mail : "It has been really hot in the continent recently, with Spain recently having the highest temperature it has ever recorded of 47.3C.
"It's not going to be that hot here, but the wind is turning more southerly and a lot of hot and humid air is coming up which could create quite a lot of thunderstorms."
The combination of extreme high temperatures and intense rainfall means there's potential for flash flooding, damaging hail storms and tornado formation.
