London weather forecast: THIS is when lightning storms will batter capital – latest maps

Thunder and lightning storms develop when there is instability in the atmosphere. They are extremely common occurrences on Earth and it is predicted that a lightning strike hits somewhere on the Earth’s surface about 44 times a second – equating 1.4billion lightning strikes in a year. In Britain, the most common areas for thunder and lightning storms are over the East Midlands and the south-east regions. Here is when lightning storms are expected in London.


Most of Wednesday, August 11, is expected to be warm in continuing with temperatures of recent weeks.

There are low chances of rain predicted, with BBC Weather saying there is a six percent chance of downpours.

Most of the day should have uninterrupted sunshine until cloudy intervals begin showing into the evening.

Temperature highs today are expected to reach a balmy 31C.

After 5pm, however, the chances of downpours become significantly higher, rising from 10 percent to 35 percent by midnight.

There could be thundery spells around 8pm, with more thunder forecasted to strike from 11pm onwards.

AccuWeather predicts that thunderstorms will hit the capital earlier, starting at around 6pm.

The likelihood of rainfall will also increase in the evening and into the night, most likely hitting after midnight.


The weather on Thursday, August 13, is expected to be much more turbulent and unsettled.

There is a relatively high chance of rain all day in London, ranging from 24 percent in the morning to 25 percent in the early evening.

For city dwellers struggling to cope with the tropical heat, tomorrow should offer some respite with lows of 21C predicted overnight.

The thundery weather from Wednesday is expected to continue overnight, however.
