Marion County Road Department trucks are back to work early Wednesday morning.

Blowing and drifting snow, reduced visibility, and slick roads will be a factor on both gravel and paved roads throughout the overnight and into tomorrow.

Trucks and motor graders will start on paved and gravel roads at 4:00 a.m. Wednesday.

Snow ordinances will be in effect tonight for Knoxville, Pella, and Indianola. Widespread snowfall amounts of 3-6″ are expected through early Wednesday.
