Sudden fall indicates: Storm.
Slow fall indicates: Rainfall.
Slowly raises indicates: Clear sky.

At rainfall low temperature is formed.

@Appi has explained very well.
Let me try Rain fall means flow of cloud from high press reason to low press reason.
Barometer is press measuring instrument, it gives atmospheric pressure reading, it mean it sense the low pressure at the time of rain fall.

First of all, barometer is a pressure measuring device and and when there is a storm which is formed due to low pressure in its center barometer should show sudden downfall of reading. Its got nothing to do with rainfall.

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.

It should be storm rain should not link with pressure.

Barometer mainly used to measure the pressure. If its readings goes down it shows rainfall.
