May it could be explained in terms of vapour pressure. Since it is used for measuring atmospheric pressure, intense heat would increase pressure (more evaporation thus increasing vapour pressure), rainfall (condensation i.e, conversion of vapour to water) will reduce vapour pressure, consequently, decrease in atmospheric pressure.

As the pressure drops the saturation temperature of vapours goes down will start condensation thus an indication of rainfall.

Because humid air is less dense than dry air.
So,ATM pressure decrease that's why barometer reading fall.

A device that measures air pressure and shows when the weather is likely to change.
