Cirrostratus clouds art the least likely to produce precipitation that reaches the ground. These clouds are often formed from cirrus clouds as a warm front approaches.
Nimbus clouds are likely to produce precipitation, such as rain, snow, hail, or sleet. These clouds are characteristic of stormy weather conditions and typically bring wet weather.
Cumulus clouds may bring rain, but not always. Whether or not a cumulus cloud produces rain depends on factors such as the atmospheric conditions, moisture content, and vertical development of the cloud. Cumulus clouds that grow into towering cumulonimbus clouds are more likely to produce rain.
Cumulus clouds can produce rain if they grow large and tall enough to develop into cumulonimbus clouds, which are known for generating thunderstorms and precipitation. When cumulus clouds reach this stage, they can release rain.
Nimbostratus is the name of the cloud that can appear at low or mid level and appears as a heavy gray rain cloud.
The cloud is called a nimbostratus cloud. These clouds are thick and produce continuous precipitation, often resulting in steady rain or snow. They typically form in the middle to low levels of the atmosphere.
