Why is rain so cold?

Can it rain at 30 degrees?
The local weather report only gives us the ground-level temperature. As it falls, it may travel through a layer of air that has a temperature greater than 32 F (0 C). This layer melts the snow into rain. If the temperature at ground level is below freezing, then the water may refreeze in the air, and we get sleet.

Where are the rain shadows in the world?

What is the historical range of rainfall in the United States?
This historical range is indicated by the 10 th percentile (a one-in-ten-year low rainfall outcome), the 50 th percentile or median, and the 90 th percentile (a one-in-ten-year high rainfall outcome). The range between the 10 th and 50 th percentile is shaded brown.
