Tom Purdy uploaded this incredible photo to Facebook Sunday, taken in Beloit, Wisconsin. These are "light pillars" created as street lights intercept ice crystals of different dimensions in the atmosphere. I first blogged about them in 2008.

These particular pillars are flared at the top, something I hadn't seen before. Tom's photo went viral on Reddit, but it wasn't the only one taken that night... the viewer photo sent into WKOW, shown below, adds something new: snowflakes! What a night!

The video below will give you a primer on how light pillars form; Capital Weather Gang has a detailed explanation of why these looked the way they did.
