How does the current barometric pressure affect weather?

Answer by  PZ (1206)

In general when barometric pressure decreases, except rain, storms and windy weather. When it rises, fair, dry and colder conditions are on the way. If the barometric pressure drops quickly in a short period of time, a storm is likely within the next 24 hours.

Barometers measure the weight of the atmosphere above it. High pressure systems will bring good weather, where as areas of low barometric pressure will bring bad, or atleast worse, weather with them. The greater the pressure difference between the two systems, the stronger the wind will be when those systems colide.

When the barometric (air) pressure is high, the weather is warm and sunny. When it begins to drop, that is an alert that rain or stormy weather may be approaching. A large drop in barometric pressure, especially following a short rise in pressure, indicates a very bad and prolonged storm will soon arrive.

Rising pressure brings fair, sunny weather, which lowering pressure means precipitation. When warm air rises quickly, the pressure falls and the air cools, forming clouds and then rain.

Barometric pressure will get higher when there is a storm coming. There is usually a surge of low pressure and then it will become more pressurized when the storms closer
