Hot weather causes surface water to evaporate into the atmosphere.
As the warm air continues to rise, the water droplets combine to create larger droplets which freeze to form ice crystals. As result of circulating air in the clouds, water freezes on the surface of the droplet or crystal.
Eventually the droplets become too heavy to be supported by air and they fall. As the droplets move through the cloud, they pick up a negative charge by rubbing against smaller positively charged ice crystals.
The negative charge is attracted to the Earth's surface and other clouds and objects and when the attraction becomes too strong, the positive and negative charges come together, or discharge, to balance the difference in a flash of lightning (sometimes known as a lightning strike or lightning bolt).
The rapid expansion and heating of air caused by lightning produces the accompanying loud clap of thunder.
