Air 68 degrees Fahrenheit can hold twice the amount of water of air 50 degrees Fahrenheit

 begin quote from:

Hot air expands, and rises; cooled air contracts – gets denser – and sinks; and the ability of the air to hold water depends on its temperature. A given volume of air at 20°C (68°F) can hold twice the amount of water vapor than at 10°C (50°F).
