According to folklore, "ring around the moon, storm is coming soon" may very well be coming true with the next winter storm expected Wednesday.
For the latest weather forecast, click FORECAST.
A moon ring, also called a “22 degree halo,” is actually caused by very high level cirrus or cirrostratus clouds that normally precede a stormy weather front.
The thin wispy clouds contain tiny hexagon shaped ice crystals that cause the moon’s light to refract (bend) to a 22 degree angle.
Inside the halo, the area seems darker because light cannot be refracted sharper than 22 degrees.
These two processes combined make for one beautiful but foretelling sight to behold.
