Is the sultry air pressure low or high before it rains?

Before it rains, sultry weather means low air pressure. Before it rains, the temperature will drop and the air pressure will drop. Air molecules with higher pressure are squeezed out by water vapor molecules and spread to the periphery of the rain belt. The change of atmospheric pressure is closely related to the weather. Generally speaking, the air pressure in sunny days is higher than that in cloudy days, and the air pressure in winter is higher than that in summer.
