An interesting local phenomenon will occur occasionally across McCracken County, when cold arctic air spreads into western Kentucky from the northwest. Warm air rising from the stacks at the Shawnee Fossil Plant, and from USEC will interact with the very cold air to produce clouds, and occasionally snow flurries.
