What will the weather be like before it rains?

Generally, before the rain comes, the air humidity will increase greatly and the air pressure will drop significantly.

Since ancient times, people are familiar with the warning signals before rain, such as frogs chirping and swallows flying low, with high accuracy. There are several others:

Ants crossing the road-ants digging holes in the ground think that the holes will be flooded when it rains, that is, they will run away before it rains.

Earthworms come out of the hole-the ground is wet and soft, and earthworms will climb out of the ground, which indicates that it will rain.

Other signs before rain are swarms of mosquitoes and rain ants.
