Which of the following is a sign of continuing fair weather?

Red sky at night signals continuing fair weather because it usually means a high-pressure, stable air mass is moving in, bringing dry, settled conditions. When the evening sky reddens, it indicates clear skies and an approaching high-pressure system, which often persists and keeps the weather fair for the near term. In contrast, a rapidly falling barometer points to a low-pressure system and potential storminess, thickening clouds with dark clouds signal an approaching front and deteriorating weather, and dense fog along the coast at midday suggests localized low visibility and moisture but not a reliable sign of ongoing fair weather.
