Answer:
As the barometer lowers one can expect a cloudy, rainy or snowy weather.
Step-by-step explanation:
A barometer is an instrument used to measure the air pressure or atmospheric pressure. The normal value is around 760 mmHg (millimeter mercury). However, weather patterns are affected by changes in pressure.
A rise in the barometric pressure indicates a rise in the air pressure which results in dry and clear weather. In contrast, as the barometer pressure lowers the surrounding air pressure also drops which facilitates a cloudy or snowy weather.
