Single cell storms form when the atmosphere is unstable, but there is little or no wind shear, meaning precipitation falls back down through the updraft that led to it, cooling it and eventually killing it. These storms are short lived, and last for less than an hour after becoming strong enough to produce lightning. Days with suitable weather conditions often see the repeated forming and dissipation of such storms, leading them to be known as "pulse" storms.
A thunderstorm, or an electrical storm, is a form of weather characterized by the presence of lightning and its attendant thunder. It is usually accompanied by copious rainfall, hail, or rarely, snowfall in the winter months, sometimes termed thundersnow.
Thunderstorms occur throughout the world, even in the polar regions, with the greatest frequency in tropical rainforest areas, where they may occur nearly daily. Kampala and Tororo in Uganda have each been mentioned as the most thunderous places on Earth, an accolade which has also been bestowed upon Bogor on Java, Indonesia. In temperate regions, they are most frequent in spring and summer, though can occur in cold fronts at any time of year. Probably the most thunderous region outside of the Tropics is Florida. During the summer, violent thunderstorms are an almost daily occurrence over central and southern parts of the state. The most powerful and dangerous severe thunderstorms also occur over the USA, particularly in the Midwest and the southern States. These storms can produce very large hail and powerful tornadoes. Thunderstorms are rare along the West Coast of the United States, though they do occur more frequently in inland areas.
Thunderstorms form when significant condensation—resulting in the production of a wide range of water droplets and ice crystals—occurs in an atmosphere that is unstable and supports deep, rapid upward motion. This often occurs in the presence of three conditions: sufficient moisture accumulated in the lower atmosphere, reflected by high dewpoint temperatures; a significant fall in air temperature with increasing height, known as a steep adiabatic lapse rate; and a force such as mechanical convergence along a cold front to focus the lift.
Thunderstorms have had a lasting and powerful influence on early civilizations. Romans thought them to be battles waged by Jupiter, who hurled lightning bolts forged by Vulcan. Thunderstorms were associated with the Thunderbirds, held by Native Americans to be a servant of the Great Spirit. In more contemporary times, thunderstorms now have taken on the role of a curiosity. Every spring, storm chasers head to the Great Plains of the United States and the Canadian Prairies to explore the visual and scientific aspects of storms and tornadoes.
According to Encyclopedia Britannica, if the quantity of water that is condensed in and subsequently precipitated from a cloud is known, then the total energy of a thunderstorm can be calculated. In an average thunderstorm, the energy released amounts to about 10,000,000 kilowatt-hours, which is equivalent to a 20-kiloton nuclear warhead. A large, severe thunderstorm might be 10 to 100 times more energetic.

Lightning is all about eletric discharge and grounding from two gradients (sky and ground).
Thunder is the byproduct of lightning heating the air and the air expand quickly generating the sound
Rain usually happens during the weather system of 2 different temperature gradient (pressure, temperature, etc.). Usually the gradient could induce a high electic gradient and hence lightning and thunder.
But Lightning and thunder only needs the electrical gradient

Rain occurs when the water droplets are large enough to overcome the updrafts in a given cloud formation. Often this does not occur, yet there is sufficient electrical potential difference within the cloud to allow lightning to form.

Lightning is the cause of thunder, static electricity is the cause of lightning, but rain is caused by condensing of water molecules to the point where they get heavy enough to fall. Sometimes we get shocked by walking on a rug and building up a static charge, then touchng something that allows the charge to conduct, but rain doesn't come out of us.

Usually in such cases, there's a strong wind that blows away the clouds and it goes and rains over some other area or the ocean/seas
