As a barometer lowers what kind of weather can be expected

The weather is expected to become cloudier and stormier

Explanation:
Barometer is an instrument used to predict the weather.
This prediction depends on the change in the pressure.

There are two possibilities for the pressure:
low pressure which usually indicates heavy rains and storms
high pressure which usually indicates warm and dry weather

When the barometer lowers, this means that the pressure decreased which means that the possibility of clouds, rains and storms is high.

Hope this helps :)
