The tense used in the underlined sentences is suitable for the context.

Here is the step-by-step explanation:

1) "Would never go out if it was raining" - The use of the past simple "was" is appropriate here because it describes a habitual action in the past.

2) "Used to look up at the sky whenever it was getting cloudy" - The use of "used to" is suitable here because it indicates a repeated action or habit in the past. The past continuous "was getting" emphasizes the ongoing nature of the action.

3) "It was getting cloudy" - The use of the past continuous "was getting" is correct because it describes an ongoing action in the past that was interrupted by another event.

4) "Was falling" - The use of the past continuous "was falling" is appropriate here because it describes an ongoing action in the past that was interrupted by another event.

5) "Had scuttled back into her house" - The past perfect "had scuttled" is suitable here because it indicates an action completed before another past action or event.

6) "Was locking herself in her bedroom" - The use of the past continuous "was locking" is correct because it describes an ongoing action in the past.

In conclusion, the tenses used in the underlined sentences are suitable for the context, and no corrections are needed.
