Quizplus · Accepted Answer

The interpretation of a halo around the Moon as a sign of impending rain (or snow) stems from the association of cirrus clouds with cyclonic storms. These high-altitude clouds often appear before a storm and can create a halo around the Moon due to the refraction of Moonlight through ice crystals in these clouds. Therefore, the presence of a halo around the Moon indicates the presence of these cirrus clouds and can be a sign of approaching bad weather.
