10) Does it ever snow in the "mystery city"? Explain your answer using information from the climograph.

- The mystery city has a cold winter with temperatures dropping to about 20°F in January.
- The precipitation in winter months (Dec, Jan, Feb) is moderate, but not extremely high.
- However, temperatures drop below freezing, especially in January.
- Since the temperature can go below 32°F, and there is precipitation, it’s possible that snow falls.
- Additionally, the coordinates given are Lat: 41°52'N, Long: 87°37'W, which is near Chicago, IL — a city known for snow.

✔ Answer: Yes, it does snow in the mystery city.
Explanation: The temperature drops below freezing (around 20°F in January), and there is precipitation during winter months. This combination indicates that snow is likely. Also, the location matches Chicago, which experiences snowfall.
