Before the warm front arrives, the cloud cover would be

Question

BlackTom AI · Accepted Answer

To approach this question, first recall how weather fronts influence cloud formation. A warm front typically brings an extensive, layered sky as warm moist air gently rises over cooler air, leading to widespread, uniform cloud cover rather than isolated, towering clouds.
Option: stratus. This choice aligns with the idea of broad, flat, low-altitude cloud decks that often cover large areas ahead of a warm front, producing a gray, overcast look. It reflects pervasive cloudiness rather than breaks of sun.
Option: none. Claiming there would be no clouds before the warm front is inconsistent with basic forecast logic, since air mass interactions at a front generate clouds; total cloudlessness is highly unlikely in this scenario.
Option: cumulonimbus. These tall, thunderstorm-producing clouds are associated with strong lifting and instability commonly found along cold fronts or vigorous convective environments, not the gradual, stratified ascent seen with warm fronts.
Option: fair weather cumulus. While cumulus clouds can appear in fair weather, they tend to be discrete, puffy clouds indicating localized heating and weaker, convective activity, not the widespread, continuous cloud cover typical of a warm-front approach.
Taken together, the best fit for cloud cover prior to a warm front is a stratified, layered cloud structure—precisely what stratus implies—while the other options describe cloud types or states that do not match the expected pre-front pattern.
