falling pressure
Storm indicator reading
Falling pressure describes a decrease in atmospheric pressure, typically indicated by a barometer.
Meteorologists use it to predict approaching weather changes, usually signaling incoming storms, rain, or unsettled conditions: The falling pressure suggests we're in for some rough weather.
The phrase applies to other contexts where pressure decreases—hydraulic systems, blood pressure, or tire inflation.
