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.
Not necessarily. A drop in barometric pressure can indicate an approaching weather system, but it doesn't guarantee rain. Other factors like humidity and temperature also play a role in determining whether it will rain.
Changes in atmospheric pressure are one of the most commonly used ways to forecast changes in the weather because weather patterns are carried around in regions of high and low pressure (see Air Mass). A slowly rising atmospheric pressure, over a week or two, typically indicates settled weather that will last a long time. A sudden drop in atmospheric pressure over a few hours often forecasts an approaching storm, which will not last long, with heavy rain and strong winds. Pioneering meteorologist Vice-Admiral Robert Fitzroy once noted: "long foretold, long last; short notice, soon past".
By carefully watching the pressure on a barometer, you can forecast local weather using these simple guidelines:
- Decreasing barometric pressure indicates storms, rain and windy weather.
- Rising barometric pressure indicates fair, dry, and colder weather.
- Slow, regular and moderate falls in pressure suggest a low pressure area is passing some distance away. Marked changes in the weather are unlikely.
- Small rapid decreases in pressure indicate a nearby change in weather. They are usually followed by short lasting wind and showers.
- A quick drop in pressure over a short time indicates a storm is likely in 5 to 6 hours.
- Large, slow and sustained decreasing pressure forecasts a long period of poor weather. The weather will be more pronounced if the pressure started rising before it began to drop.
- A rapid rise in pressure, during fair weather and average, or above average pressure, indicates a low pressure cell is approaching. The pressure will soon decrease forecasting poorer weather.
- Quickly rising pressure, when the pressure is low, indicates a short period of fair weather is likely.
- A large, slow and sustained rise in pressure forecasts a long period of good weather is on its way.
For pressure tendency, the definitions used by these guidelines are:

There are powerfull winds in the higher atmosphere that blow in or suck out in any direction and change at random times.
In most storms air generally moves upwards. This results in the atmosphere pressing down with less force.
because when air pressure drops all the good air goes down. The top air then gets gray clouds and rain starts to fall.

What happens to the barometric pressure in a hail storm?
In most storms, which always includes hail storms, the barometric pressure drops. Which the pressure drops, that would allow clouds to form. The more it drops, the more intense the storm can get.
What does up when the rain comes down?
If you mean what 'goes' up when the rain comes down, then the answer is the barometric pressure. A low pressure cell, which is a chief indicator of a rain storm, occurs when the barometric pressure drops below 30 points. As the storm dissipates, the low pressure cell changes, causing the barometric pressure to rise.
What method would be best to determine the barometric pressure is changing will lead to rain?
analog
What would be the best method to determine whether the way the barometric pressure is changing will lead to rain?
One way to determine if a change in barometric pressure will lead to rain is to observe the trend over a period of time. A rapid decrease in barometric pressure often indicates an approaching storm with potential rainfall. Additionally, comparing the current pressure to regional weather patterns can provide insight into the likelihood of rain.
What method be the best way to determine weather the way the barometric pressure is changing will lead to rain?
Tracking the trend of barometric pressure can help predict weather changes. Generally, a rapid decrease in barometric pressure indicates an approaching storm or rain, while a rising pressure usually suggests clearing weather. Additionally, comparing pressure readings with weather forecasts can provide more accurate predictions.

Does barometric pressure go up or down in tornadoes?
Barometric pressure typically drops significantly in the vicinity of a tornado due to the strong updrafts and intense low-pressure system associated with the storm.
How are blood pressure and barometric pressure associated?
Changes in barometric pressure can affect blood pressure, especially in individuals who have cardiovascular conditions. When barometric pressure drops, it can cause blood vessels to dilate, leading to lower blood pressure. Conversely, when barometric pressure rises, it can cause blood vessels to constrict, resulting in higher blood pressure.

What does the barometric pressure do during a snow storm?
During a snowstorm, the barometric pressure typically decreases. This drop in pressure signals the approach of the low-pressure system associated with the storm. The decrease in pressure can also lead to a rise in wind speed and precipitation, often resulting in heavier snowfall.
Why did it rain in 2004 flood the flood of battlecastle?
Because conditions were right..Temperature, Barometric Pressure, Humidity
What is the weather instrument?
Barometer (barometric pressure) Thermometer (temp) & rain guage (amt of rainfall in inches)
What happens when barometric pressure increases?
When the barometric pressure rises it means calm fair weather is coming or is already occurring. When the barometric pressure falls it means foul weather is on the way such as rain and storms and clouds.
What type of weather does low barometric pressure usually create?
Low barometric pressure typically creates stormy or unsettled weather conditions. This can include cloudy skies, precipitation such as rain or snow, and possibly strong winds.
