Does the stuffy weather mean that it will rain soon?

There is always a sultry period before it rains, and there is little cool wind. Summer rainfall is generally caused by the combined influence of cold air and warm and humid airflow, and sultry is the expression of the increase of water vapor and temperature in the atmosphere. This is also a precursor to summer thunderstorms. ?

The rain in summer is mostly showers and thunderstorms, which is due to the fine weather, high temperature and strong air convection in some areas, which makes a large number of hot and humid air rise sharply and form cumulonimbus clouds. At the same time, the hot air in the atmosphere is increasing and the water vapor is sufficient. At this time, although the temperature changes little, because there is a lot of water vapor in the atmosphere, it has become saturated, and the water on the ground is difficult to evaporate, and the sweat on people is also difficult to evaporate, so it will feel very stuffy and uncomfortable.
