I want to know the answer to the following question:
What are Tucson's typical winter low temperatures?
All the background I'm provided with is that "Daytime highs in the winter range between 64 and 75 °F (18 and 24 °C), with overnight lows between 30 and 44 °F (−1 and 7 °C).". Is that enough to answer the question?
Answer: yes
