A barometer measures air-pressure (baro-meter) so a rising reading means the local air pressure is increasing. If we assume that your local gravity is constant (it usually is) then the increasing air pressure is caused by the air getting denser; more kilograms per cubic metre or pounds per pint. That could be because the air is getting colder, or because it has less water content, since making air colder makes it denser, and dry air is denser than wet air. So, a rising barometer suggests a spell of cool dry weather.
A rising barometer indicates that the air pressure is rising and this is associated with clear skies with few cloud formations. Generally this will mean it is hotter than average in summer, but colder than average in winter.
A rising barometer means higher pressure which means less clouds and fairer weather.

Is rising air associated with a low pressure cell?
First answer was incorrect (in this thread)....Here's the breakdown:Regions of sinking air are called highs, high pressure regions or anticyclones. Clear skies and fair weather usually occur in these regions.Regions of rising air are called lows, low pressure regions, depressions or cyclones. Clouds rain and strong winds often occur in these regions.
Barometer are used to predict weather because weather is related to changing what?
The weather changes in relation to the air pressure. Air molecules always travel towards low pressure where there is less force acting on them. This has an effect on the weather. Generally, high pressure means good weather and low pressure means bad weather. Barometers measure the pressure, often in Hectopascals.
Which environments would often have humid weather?
Equatorial low pressure environments mostly
Will it rain when barometric pressure drops?
Actually it's the other way around because decreasing barometric pressure initiates the upward flow of air that is essential for cloud development and then rain. Hope this helps! :) Actually no, because decreasing barometric pressure at the surface is a result of rising air and it also causes convergence of air at the surface. Sometimes in thunderstorms when the downdraft (ie rain and hail) is intense, it can actually cause a rise in barometric pressure at the surface since the air has a strong sinking motion hence the name downdraft. Thanks to the above user for attempting to give a correct and complete answer, but this answer from me is more correct and complete.
What can a barometers be used for?
A barometer measures barometric pressure, that is, atmospheric pressure. Because air flows from high pressure areas to low pressure areas, rising or falling barometric pressure tells us that we should expect a change in the weather. For example, a storm is often preceded by a drop in barometric pressure. A barometer is an indispensable tool for a meteorologist, a captain of a ship, or anyone else who needs to predict the weather.
What is the high and low pressure?
meteorology and weather. In high pressure the air presses down with more force than usual. This usually means air is sinking. High pressure systems typically bring calm, clear weather. In low pressure air presses down with less force than usual. This most often indicates rising air. Low pressure systems often bring cloudy or stormy weather.
When there is nice weather there is often a pressure system?
When there is nice weather, you are under the influence of a high pressure system,
What is a high air pressure system known as?
areas of high pressure often have a clear sky.areas of low pressure are often cloudy
In summer southern europe often has high pressure what effect does that have on the climate?
High pressure means nice weather, so Southern Europe often has nice weather.
What the result of colder air moving to replace rising warmer air?
generally a low pressure weather system, often causing low temperatures, strong winds and precipitation (rain. snow or hail)

Which type of weather is most often associated with fluffy white clouds?
How would weather conditions in an area change if a high pressure system replaced a low pressure

How does change in the air pressure affect weather?
Generally with high surface pressure, there is sinking air and clear skies. With low surface pressure there is rising air with clouds and precipitation given sufficient moisture.
What kind of mass does Stormy Weather have?
Stormy weather often occurs along the boundary between air masses or in association with a low pressure system.
