Is humidity always high when raining?

Most of the time when it is raining the relative humidity is 90-99 percent, but not often is it 100 percent. Clouds form when invisible water vapor gas condenses into visible water droplets, and rain occurs when droplets grow too large to be supported in the air and they fall.
