I looked up at the sky & there was a ring around the moon. It wasn't actually on the moon though. It looked like a cloud except it was in a ring shape & it was blueish. It was wide & it was formed so that the moon was in the center. Sort of like this ( • )

Where I live (northern temperate latitudes), this usually means precipitation within 24 hours.
Halo formed by ice crystals through a veil of Cirrostratus clouds, the leading edge (at high altitude) of an approaching warm front, bringing humid air.
Though the cirrostratus, bright stars are still visible.
After the cirrostratus come the thicker altostratus: the Moon is still visible (barely) but has no halo.
As the cloud thickens, the Moon eventually disappears. It gradually become a Nimbostratus, with precipitation (light at first).
This kind of front is rarely violent (no lightning, usually). Winds shift to warmer directions and the air gets less cold (but more humid) as the ground front passes over your location.

It was a lunar halo, caused by ice crystals in Earth's upper atmosphere reflecting and refracting the Moon's light.
