Thunder & Lightning...

At about 7.30pm this evening,there was a sudden change in the weather.Suddenly,strong flashes across the sky.And then there was thunder.I look out into the sky,THE SKY WAS RED IN COLOUR!My brother haven't come home,wondering where is he.Messaged Yiru to ask her but she say he left quite sometime already.
The flashes in the sky is getting worse ans worse.The brightness of the flash can be as bright as the daylight.It is terrifying.
Not long after,my dear brother came home and the sky start to pour.The rain was so heavy,it is still quite rare to happened.But the more rarer thing happened.The rain just come and go so fast.And the thunder + lightning + the rain did not kill the heat.After that,the weather is still so hot.So what does the thunder + lightning + the rain means?
