Barometric pressure decrease indicates coming stormy weather, rain, wind, , heat. Barometric pressure rise indicates fair, dry, colder weather. Slow, regular and moderate fall in pressure indicates low pressure area is passing at a distance. Any marked change in weather unlikely. Sudden decrease, even if small, indicates a nearby disturbance; normally bringing wind, and short showers. Large pressure drop signals a coming storm in 5 to 6 hours. Large, slow and sustained decrease indicates a long period of poor weather. Coming weather will be more pronounced if pressure started rising before dropping. Sudden rise of pressure,when the pressure is about average or above average and the weather is fair, indicates approach of a low pressure cell, and the barometer will soon start to come down. Rapid rise when the pressure is low, announces a short period of fair weather. If pressure rise is large and prolonged, count on a many days of good weather ahead.

The pressure tendency will likely be falling as stormy weather approaches. This drop in pressure indicates that the atmospheric conditions are becoming unstable, which is often associated with the development of precipitation and strong winds.

If fair weather is approaching the pressure tendency would probably be?

The pressure tendency would likely be rising if fair weather is approaching. This is because high pressure systems are associated with fair weather, leading to a rise in atmospheric pressure.

When does a barometer indicate stormy weather?

A barometer indicates stormy weather when the atmospheric pressure drops rapidly. A sudden decrease in pressure suggests that a storm system is approaching, typically bringing strong winds and heavy rainfall. This drop in pressure can be a sign that unsettled weather is on the way.

Which weather change is most likely indicated by rapidly falling air pressure?

Rapidly falling air pressure is often associated with an approaching storm or low-pressure system. This can indicate that inclement weather, such as rain, strong winds, or even thunderstorms, may be on the way.
