Before the cold front arrives, the cloud cover would be

Question

BlackTom AI · Accepted Answer

Question restatement: Before the cold front arrives, the cloud cover would be the following among the options: none, cumulonimbus, stratus, fair weather cumulus.
Option 1: none. This would imply completely clear skies. In the context of a cold front approaching, you generally expect some cloud formation rather than a completely clear sky, so this option is unlikely.
Option 2: cumulonimbus. Cumulonimbus clouds are tall and associated with strong convection, thunderstorms, and heavy precipitation typically linked to active weather systems rather than the lead-up before a cold front. So this choice overstates the intelligence of cloud development for pre-front conditions.
Option 3: stratus. Stratus clouds are low, widespread sheets that often blanket the sky, commonly associated with overcast conditions and gradual weather changes preceding frontal passage. They fit the scenario of increasing cloud cover before a cold front.
Option 4: fair weather cumulus. These are puffy, isolated clouds indicating fair weather with some vertical development, but they usually imply more breakable and cumulus-type cloudiness rather than the uniform, overcast cover expected ahead of a cold front.
Putting the reasoning together, the cloud cover description that best matches the lead-up to a cold front is widespread, low-lying stratus clouds, which produce overcast skies rather than clear skies or isolated fair-weather clouds. The other options describe cloud types or sky conditions that do not align with the typical advance of a cold-front environment.
Therefore, the most appropriate choice among the given options is the one describing stratus clouds.
