What conditions are generally expected with stratus clouds?

The presence of stratus clouds is generally associated with certain weather conditions characterized by overcast skies that can lead to fog and reduced visibility. Stratus clouds are low-level clouds that form in uniform layers, often resulting in a gray, cloudy sky. They are typically indicative of stable atmospheric conditions and can produce light precipitation, such as drizzle or mist, rather than steady showers.

When stratus clouds form, they can create a thick layer close to the ground, which often results in fog. This is why the correct response highlights conditions like fog and low visibility, as stratus clouds are frequently the cause of such phenomena. The other options suggest weather patterns that do not align with the characteristics of stratus clouds; for instance, the mention of thunderstorms and clear skies directly contradicts the cloud type in question. Therefore, the accurate depiction of stratus clouds points towards the likelihood of fog and low visibility conditions.
