Excuse me, when is the weather forecast cloudy to light rain?

The change from cloudy to light rain includes cloudy days and light rain, that is, the first half of the forecast period is cloudy and the second half is light rain.

For example, from today's night to tomorrow's day, it turns cloudy to light rain, which means: cloudy at night, light rain tomorrow; Today it turns cloudy to light rain during the day, which means: cloudy in the morning, light rain in the afternoon, and so on.
