In order to know that a storm is coming, you need to know the air pressure. Storms are normally associated with a Low Pressure System. A Barometer can be a tool you can use to predict an oncoming storm.
Falling air pressure is usually an indication that a storm is coming.
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.
Weather maps show changes in wind directions, cloud and storm formations. Meteorologists can tell when a hurricane is forming or when a rain storm is coming by using this map.
I bought a digital weather station recently so I've been studying the various features one of which is a digital barometer. This particular one lets you set the altitude of your house for greater acuracy. A barometer's range as I understand it is from 28 to 32 inches. When the barometer falls it is indicating a change in the weather such as rain or a storm. The lower the number goes the more severe the storm. When it rises it indicates that better weather is coming. Remember, though, a barometer tells you what the weather will be not what the weather is. My instrument seems to predict what the weather will be in about 12 hours with a fair amount of acuracy. By the way the unit I bought was a relatively inexpensive one from Radio Shack and it seems to be fine
A fall in atmospheric pressure - an approaching storm system.A:A barometer measures air pressure: A "rising" barometer indicates increas­ing air pressure; a "falling" barometer indicates decreasing air pressure. A:Lower pressure, more clouds, and less fair weather.
A Barometer.

it is a storm is coming
Follow the weather news on Television.
Air Pressure
A storm watch indicates that a storm of a given type may be possible in your area. They basically inform people to be on alert for dangerous weather conditions.
An approaching storm

Weather the storm.
r u that thick? only god controls the weather lol
Spiders will tell you if a storm is coming. Spiders, like many other insects and animals can tell if there will be rain. When a spider senses a storm's coming they leave their web and go somewhere else. or... you could check the weather channel...
