It means the weather is going to change. If the pressure rises, i.e- the dial points to fair, or v. dry, it means the weather should be fair or v. dry. Obviously, Vice versa for the other side of the dial.

What does rapid changes in the barometer mean?
a barometer calculates changes in air pressure. so if it has a rapid change, im guessing it has just been a "rapid" change in air pressure
How to Predict the Weather Using a Barometer?
Of all weather instruments essential to forecasting, the barometer tops the list. Why? Because every weather change is preceded by a rise or fall in air pressure, and air pressure is just what the barometer measures. If you compare two barometer readings taken an hour or two apart, you will know immediately if the air pressure is rising, falling, or staying the same. And as a result you will be able, with a fair amount of accuracy, to predict tomorrow’s weather. RISING BAROMETER: When the air pressure measures higher than it did in your previous reading, the air is becoming denser, and the barometer is said to be rising. This tells you that clearer, drier, cooler weather is on the way. If the barometer is rising very rapidly from a low position, the weather will clear up very soon, and it will probably become quite windy. But if the barometer rises from a low position gradually and steadily, a long period of good weather is just around the corner. If the barometer is already high and suddenly starts to rise rapidly, expect a sudden drop to follow shortly, and with it, bad weather to come. FALLING BAROMETER: A falling barometer usually indicates rain, wind, and warmer weather. Take note of the speed at which the barometer falls. A very large and rapid drop in air pressure is a sure sign of an approaching storm. If the barometer falls suddenly, but not too far, expect wind and brief showers. If the barometer falls slowly and steadily to a moderately-low position, it may rain nearby, but not necessarily in your immediate area. UNCHANGING BAROMETRIC PRESSURE is a pretty good indication that whatever weather you’re currently enjoying is not about to change any time soon. IMPRESS YOUR FRIENDS AND NEIGHBORS! With a little experience in charting barometric pressure in your area, you will soon become skilled at noting any changes which are out of the ordinary. At this point, your weather-predicting abilities may begin to rival those of your local TV weatherman. And that would be something to brag about!
Why does knowledge of weather fronts help scientist predict weather?
Especially in temperate latitudes, fronts are the primary bringers of changes in the weather. They are responsible for most rapid changes in weather and a large portion of the snow, rain, and thunderstorms that occur in most regions.
Can you get headaches when the weather suddenly changes?
Yes, some people are sensitive to changes in weather and may experience headaches or migraines as a result. Rapid changes in temperature, humidity, or barometric pressure can trigger these headaches in susceptible individuals. It is thought that these weather-related headaches are due to changes in the brain's blood vessels or levels of certain chemicals.
Why do disruptive selection pressures tend to favor rapid evolutionary changes?
They result in sudden gene frequency changes.

Can a steep curve in a line graph indicate a rapid or a slow rate of change?
its going to be a rapid rate of change because it changes fast. a slow rate would be a steady or a smaller curve
What should a barometer measure when there is a tornado?
If a tornado passes near or over a barometer, it will measure a very rapid drop in pressure. How much the pressure drops depends on the strength of the tornado and how close the center of it comes tot he barometer.
