'Very Unusual' Snow Falls On Small Part Of Downtown Tulsa

If you didn't realize it snowed in Tulsa last night, you're not alone. 

It snowed on a very small part of downtown overnight thanks to exhaust fumes from nearby refineries. News On 6 WARN Team Meteorologist Alan Crone said the warm fumes crystallized and fell as snow and fog crystals.

Crone said it was a "very, very unusual phenomenon" to see in Tulsa. Snow accumulated on just a couple of parking lots located within a block or two.  

Viewer Kadie Graves sent us photos and said it snowed for about two hours in the middle of the night from the IDL to around Denver.
