(WXYZ) - We're hearing from people from across metro Detroit about this strange-looking ring around the sun.
There's no reason to be alarmed. That halo around the sun is caused by the sun's rays bouncing off the ice crystals 4-5 miles up in the sky, similar to the way a rainbow is made when light rays get bent by drops of rain suspended in the air.
The ice crystals make up those cirrus clouds that we see today. Halos aren't exactly rare, but clear ones like you may have seen don't happen all the time either.
Before modern forecasting began, people noticed that "a ring around the sun means rain or snow within 2 days." This is often the case because high clouds are sometimes the first visible sign of an approaching low pressure system that can bring precipitation. As luck would have it, there is a slight chance for a shower around here by Wednesday.
If it happens, it would come from the same weather system that's producing our highs clouds today, making the cool "ring around the sun."
