Yes. It is possible for it to rain when the humidity at ground level is less than 100%. Sometimes upper level moisture is cooled by a front, and rain forms at higher altitudes and falls to the ground. There are even related instances where rain forms high in the atmosphere, falls heavily, but evaporates before reaching the ground.

What is the dew point and what happens when it falls below the dew point?
The Dew Point is the temperature at which the air is at 100% Relative Humidity. If the temperature fall below the Dew Point, then there is more moisture in the air than it can hold, and water condenses in the form of dew, mist, rain, etc.
What does saturation have to do with dew point?
The dew point is a saturation point, but a saturation point may not be a dew point. That is, a saturation point has a broader definition -- more general application. Sometimes you can interchange the terms without confusing the reader. =================================
What is the relationship between dew point temperature and air pressure?
Dew point is the temperature at which the air reaches saturation. Warmer air can retain more moisture than cooler air. So, ignoring other factors such as pressure, when the temperature drops to the dew point temperature, the air becomes saturated and therefore, if there is actually moisture in the air (is there a cloud?), it will start to rain or snow.
What is the dew point in a hurricane?
there is no dew point of a hurricane
What is dew point in weather reports?
Dew point is the point when condensation forms
When a parcel of air reaches its dew point what process begins?
Some sort of precipitation occurs when air reaches the dew point. You might get dew, frost, rain or snow.
Why isn't dew point always the same?
The dew point is a measure of the amount of water vapor in the atmosphere. As the temperature gets closer to the dew point, the humidity rises. When the temperature finally drops to the dew point (100% humidity), the the atmosphere is completely saturated with water, and it will start to rain (or snow, if the dew point is below freezing). Since the atmosphere is completely saturated when the temperature is at the dew point, it cannot go below the dew point.
What is the dew point and what happens when it falls below the dew point?
The Dew Point is the temperature at which the air is at 100% Relative Humidity. If the temperature fall below the Dew Point, then there is more moisture in the air than it can hold, and water condenses in the form of dew, mist, rain, etc.
Why even when it's foreshadowing a big storm with dark black clouds of heaven and after a few raindrops the clouds depart and no rain?
Clouds are dark without rain when they do not reach their dew point, the temperature at which water condenses to create rain.
When a parcel of air reaches its dew point the process of what begins?
The process of air reaching its dew point is called condensation. As the air pressure reaches the dew point, the humidity increases.
What does saturation have to do with dew point?
The dew point is a saturation point, but a saturation point may not be a dew point. That is, a saturation point has a broader definition -- more general application. Sometimes you can interchange the terms without confusing the reader. =================================
What is difference between rain and dew?
rain falls while dew drizzles.
Why do your house windows fog up in the winter?
The reason frost forms on windows is due to the dew point and temperatures. The dew point is a temperature at which water in the air will condense into liquid H2O. In this case the H2O has reached the dew point and has actually frozen due to reaching a temperature of or less than 32 degrees Fahrenheit.
What is different beteew rain and dew?
Rain is a very dangerous while dew is not bad at all
What happens when air is cooled below its dew point without condensation?
supercooled
What happens to the water vapor in the air when the air is cooled to its dew point?
When water vapor reaches its dew point it then becomes saturated. Either the vapor falls as rain, or if it is a cool clear night it forms as dew on surfaces. if the surface is cold enough it can also form as frost.
What is the dew point in a hurricane?
there is no dew point of a hurricane
