A weather warning remains in place from the Met Office to prepare for "large hail and intense thunderstorms" - right in the middle of another mini-heatwave.
On Tuesday night, London was lit up with dramatic lightning displays , with some comparing it to sci-fi classic, The War of the Worlds.
Despite temperatures soaring to a blistering near 30C on Tuesday (July 18), the south east got a soaking overnight into Wednesday morning (July 19).
The rain was accompanied by a dazzling lightning storm, captured by residents across the county during the early hours of the morning.
On Tuesday, the Met Office extended its yellow warning of rain and storms from 1.15am on Wednesday (July 19) through to 10pm, with residents warned to expect further thundery showers.
The storm, which lit up the skies above west London, moved slowly northwards during the night - and made for a spectacular display.
The storms eased from the south later in the night, but the Met Office has said "severe storms" may break out again on Wednesday afternoon.
They added frequent lightning and large hail may be additional hazards, which could bring potential for disruption to power networks.
A Met Office Chief Forecaster said: "Although many places are likely to miss the worst of the rain, intense downpours associated with the thunderstorms may give over 30 mm in an hour locally and perhaps more than 50 mm in two or three hours.
"As is usual in this type of situation there is uncertainty in the worst affected areas."
The combination of extreme high temperatures and intense rainfall means there's potential for flash flooding, damaging hail storms and tornado formation.
However, Thursday (July 20) should be mainly dry and bright before Friday (July 21) sees cloud, rain and possible showers inbound.
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.
