We've guessed that you're not using a client that supports colored tables and have tried to compensate. Rain, snow, and clouds are all made of up of some form of water. Snow flakes are simply ice crystals while rain is just liquid water.
Water existing as a gas is called water vapor.
When referring to the amount of moisture in the air, we are actually referring to the amount of water vapor. Common sources of moisture for the United States are the warm, moist air masses that occasionally flow northward from the Gulf of Mexico and western Atlantic Ocean. As cyclones move eastward from the Rockies, southerly winds ahead of these storm systems transport the warm moist air northward. This moisture is a necessary ingredient for precipitation. If the moisture content of the air is very low, precipitation is unlikely to develop.
