Answer 1

The best explanation for the student's observations in the table is:

**A cold front moved into the area.**

This is supported by the combination of sunny and warm weather followed by a drop in temperature, cloudy and rainy conditions, and then clear but cold weather. A cold front typically leads to a drop in temperature and can bring about severe weather changes.
