Which weather feature is commonly associated with low ceilings and rain?

• A. Cold front
• B. High pressure system
• C. Trough
• D. Warm front

Answer: (D)

When you think about how fronts affect clouds and precipitation, a warm front is the one that tends to bring low ceilings and steady rain. A warm front slides warm air up over cooler air in a broad, gradual manner, which lifts a large layer of air and forms widespread low cloud decks—stratus and nimbostratus. Those clouds produce light to moderate rain that can persist for a long period, keeping the ceilings down across a wide area. In contrast, high pressure brings clear skies and higher ceilings, a cold front often causes more intense, shorter-lived showers with rapid changes in conditions, and a trough can bring showers as well but not the characteristic long-lasting low ceilings tied to a warm front. So the feature most commonly linked with low ceilings and rain is the warm front.
