Does a ring around the moon mean rain if the weather has been clear?
‘A ring around the moon brings rain or snow’. Another similar saying is, ‘When the moon is in her house, rain or snow will come’. When the moon has a halo or a ring around it, this is due to cirrus clouds in the higher altitudes. Cirrus and cirrostratus clouds typically proceed low pressure systems bearing moisture. These clouds also contain ice crystals which refract the light giving the impression of a ring. By counting the number of stars contained within the ring, you can fairly accurately predict how far away the rain or snow will be. Eac stat represents approximately 24 hours of time. http://www.stalkingthewild.com/weather.
