Cumulonimbus clouds are a common type of rain-making cloud. Many can climb tens of thousands of feet into the sky and can be seen from dozens of miles away. Any cloud which produces precipitation (like rain, sleet, and snow) are referred to as nimbus clouds, with cumulonimbus clouds and nimbostratus clouds being among the most common of the clouds which produce precipitation.

See the role that the 3 water states — solid, liquid, and gas — play in weather and meteorology. Plus, see what storm clouds are like and what the sizes and colors of the clouds in the sky can tell us.
While Indian Summer is not the formal name of any time of year, it is a commonly used expression that describes the sunny, warm days of fall after the color of the leaves start to change and after a frost, but before any snowfall has occurred.

The weather ultimately determines why and how the leaves turn color each Fall. A small change in the weather can easily affect how colorful the leaves will be. Things such as the amount of moisture in the soil, temperature, and even the length of the days affect what colors the leaves will eventually turn — and even the brightness and hue of those colors.

It’s one thing to look up at the lcouds from the ground. It’s another to know how high those clouds are and how many layers of clouds are up there. You can figure that out with a quick glance at a cool weather chart called a SkewT.
