Answer:
Specifically,
Explanation:
Since the narrator goes on to explain a particular kind of weather they enjoy in the winter, "specifically" would make the most sense. "Next" is used to move from one topic to another, but the narrator is still talking about winter weather. "Also" is to add something, but the narrator is specifying, not adding. "Unfortunately" implies a negative connotation, but the paragraph has a positive tone (which we can deduce from words such as "love" or "favorite"). Therefore, "specifically" would make the most sense.
