Final answer:
Cumulus clouds are generally associated with fair weather, stratus clouds can bring light rain, cirrus clouds often indicate fair weather but can signal changes, and cumulonimbus clouds are associated with heavy rain and thunderstorms.
Step-by-step explanation:
The weather descriptions provided can be matched to the cloud types to understand the type of weather they bring. Cumulus clouds are fluffy and usually indicate fair weather, although they can grow into larger storm clouds if conditions are right. Stratus clouds are flat, gray, and often cover the sky like a blanket; they can lead to light rain or drizzle. Cirrus clouds are high, thin, and wispy, typically seen in fair weather but can indicate that a change in the weather is coming. Finally, Cumulonimbus clouds are large, towering clouds often associated with heavy rain, thunderstorms, and severe weather conditions such as hail.
