When centimeters of Mercury (cmHg) are falling, it typically indicates a decrease in atmospheric pressure. This can signify an approaching low-pressure system, which is often associated with stormy or unsettled weather. As pressure drops, it can lead to cloud formation, precipitation, and other weather changes. Conversely, rising cmHg indicates increasing pressure and typically clearer, more stable weather conditions.
