Imagine calling your best friend on a Saturday afternoon while you are outside in shorts eating ice cream. When they answer the video call, they are wearing a heavy coat and shivering in a snowstorm!

Weather is what the outdoor air is like at a specific time and place. It includes temperature (how hot or cold the air is), precipitation (water falling from the sky as rain, snow, or sleet), and wind.
How do weather scientists describe these differences without guessing? Let's look at the three clues they measure.
