Answer :
Final answer:
If the temperature/dewpoint spread is small and decreasing, it is most likely that fog will develop.
Explanation:
If the temperature/dewpoint spread is small and decreasing, it means that the air is becoming more saturated with moisture. A small and decreasing temperature/dewpoint spread indicates that the air is nearing saturation and that condensation is likely to occur. In this case, if the temperature is 62 degrees F and the temperature/dewpoint spread is small and decreasing, it is most likely that fog will develop.
