When meteorologists forecast a winter storm one of the important questions they must answer is: will there be rain, snow, sleet, or freezing rain? That's often a challenging question. Because that water freezes at 32°F (0°C), a couple of degrees change in temperature can mean an entirely different form of precipitation. For example, a temperature is 34°F (1°C) means that precipitation will fall as rain. A few degrees colder could mean a snow day!
Look at the graphs below. Decide how precipitation changes form as it falls through the air at different temperatures from the upper levels of the atmosphere to the ground.
