How is an aneroid barometer read? In general, a falling hand on a barometer indicates a low pressure system is on the way with poor weather (usually a storm with snow or rain); a steady barometer means there will be no changes with the ongoing pressure system; and a rising barometer means high pressure and fair weather; an even higher reading, around 31, means an extremely dry atmosphere.
