I want to know the answer to the following question:
What climate zone does Philadelphia fall under?
All the background I'm provided with is that "Snowfall is highly variable, with some winters bringing only light snow and others bringing several major snowstorms, with the normal seasonal snowfall standing at 22.4 in (57 cm); snow in November or April is rare, and a sustained snow cover is rare.". Is that enough to answer the question?
Answer: no
