Humidity is actually a very bad predictor of rain except for the couple of hours leading up to a storm -- in which case you can probably just as easily see the storm clouds approaching yourself.
Humidity is associated with stormy weather conditions but it's not a good short term predictor by itself because 1) humidity frequently occurs without being followed by rain and 2) rain occurs frequently without first being preceded by humidity.
What normally happens is rain causes humidity, not the other way around, but even that's not true 100% of the time (while the dew point will usually go up, if it's followed by a large warm front, relative humidity can decrease).
What you probably want in order to predict rain is a barometer which measures air pressure. The faster air pressure is dropping the more likely rain is moving into your area. That combined with other indicators such as humidity (dew point) and temperature will give you a more complete picture of what kind of weather pattern you're sitting in.

What device is used to predict rain?
A barometer is commonly used to predict rain, as it measures changes in air pressure that can indicate approaching weather systems. Other tools such as radar, satellites, and weather balloons are also used by meteorologists to predict rain.
What is the instrument for weather?
An instrument commonly used for measuring weather is called a thermometer, which measures temperature. Other instruments used for weather measurements include barometers (which measure air pressure), hygrometers (which measure humidity), and anemometers (which measure wind speed).
How is a rain gauge used to predict weather?
No, a rain gauge is used to determine the amount of rain that has already fallen. A rain gauge is used to measure the amount of rain-water fall in a particular area; it can not be used to predict weather conditions. The instrument used to mease weather conditions are: weather satellite, Doppler radar, and weather balloons. These instruments the computer technology which enable them to read and predict weather conditions.
How can relative humidity and dew point be used to predict the weather?
Relative humidity expresses a percentage of humidity in the air to the maximum amount of humidity that could be in the air. For example: when the temperature rises the air will be able to hold much more humidity so the relative humidity will drop.
How can you predict rain?
Weather forecasters take a look at surface data, upper air data, surface maps, and upper air maps to make a weather forecast. Satellite observations of weather systems are also used. Separate weather instruments used to forecast weather are barometers (which measure air pressure) thermometers (to measure temperatures) anemometer (to measure wind speed) hydrometers (to measure humidity) and more. It is rather difficult to predict the weather. The answer above is how meteorologists used to try and predict weather patterns. It was a very crude method. Today meteorologists use numerical equations and algorithms solved by super-computers to predict the weather. A fairly good method of forecasting can come from pattern recognition. Persons who have lived in an area for a very long time can usually tell you what it will be like tomorrow. This is from years of pattern recognition which is also called climatology.

Can frogs be used to predict rain?
Folklore suggests that frogs croaking may be a sign of rain due to their sensitivity to weather changes, such as the increase in humidity before rainfall. However, frogs are not scientifically proven to predict rain. Their croaking behavior is more likely related to mating calls or establishing territory.
Which tense is used for weather forecast - will or going to?
Both "will" and "going to" can be used for weather forecasts. Generally, "will" is used for predictions based on current observations, while "going to" is used for predictions based on evidence or signs.
Historically people in Europe used which household pet to predict the approach of rain or bad weather?
frogs

What instruments do you use to predict the rain?
Meteorologists use various instruments to predict rain, including weather radar to detect precipitation, satellites to monitor cloud formation, and weather balloons to measure atmospheric conditions. Additionally, weather models that simulate the atmosphere's behavior are also used in conjunction with these instruments to forecast rain.
What part of speech rain?
The word "rain" can be a noun or a verb. For example, in the sentence, "I like rain." it is a noun. In the sentence "It is going to rain." it is used as a verb.
How might Cobalt Chloride be used to predict weather changes?
Cobalt chloride can be used as a weather predicting tool by changing color in response to humidity levels. In high humidity, cobalt chloride changes color from blue to pink, indicating an increase in moisture in the air. This color change can help forecast changes in weather patterns, especially in relation to moisture levels.
What is fore casters?
Forecasting is the action of predicting an outcome, for example weather forecaster's can predict from satellites what the weather is going to be like. This can be used in an organisation to predict the profit and revenue on a monthly basis.
What are the equipments used to predict an earthquake?
seismograph are used to predict an earthquake
