Solution

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.

Barometers are instruments used to measure changes in air pressure. High and low pressure systems move across the country, resulting in changes to barometric pressure.Typically, a rising barometer predicts the approach of mild weather, while a falling barometer points to the advent of worsening weather conditions.
