What is needed for thunderstorms?

Thunderstorms need moisture, an unstable atmosphere and lift, to develop.

Moisture is needed to create the clouds and rain.

The atmosphere needs to be unstable so that the air can rise and cool.

Lift is needed to get the air rising. This can be provided by fronts, sea breezes, mountains or heating from the sun.

Thunderstorms are most likely to occur in the summer months when the air is warm and moist. They are most likely to occur in the afternoon and evening when the sun has had time to heat the ground.
