The National Weather Service in St. Louis issued a winter storm warning for all of Mid-Missouri beginning Thursday afternoon and lasting until 6 p.m. Friday.
Mid-Missouri had a mix of freezing rain, sleet and snow that changed into just freezing rain that continued most of the night until 6 a.m. Friday, NWS meteorologist Mark Britt said.
There was rain throughout the day Friday and snow flurries in the afternoon, but there was only a bit of snow leftover north of Columbia toward Mexico, he said.
The storm began moving away from Mid-Missouri in the afternoon hours, with mostly dry conditions throughout the evening.
Cole County reported at least a quarter inch of ice, Britt said, but most Mid-Missouri counties, including Audrain, Osage and Boone, reported .3 inches.
Jefferson City Operations Division Director Britt Smith said crews treated the roads from 11 p.m. Thursday to 7:30 a.m. Friday. A small crew also treated some elevated surfaces Friday, he said.
Supervisors will continue to monitor the road conditions and treat them as necessary, Smith said.
Cole County Road Superintendent Bryan Boyce said his full crew treated the roads Thursday night. There were pavement areas in Centertown that were freezing and areas of Taus that weren't, he said.
"We just kind of had to go out and take care of the problematic spots where the temperatures were falling below freezing and then just kind of monitor road conditions throughout the night," Boyce said.
On Friday afternoon, Boyce said there could be a refreeze of the pavements with black ice Friday night that the crew would treat if needed.
There is a 30 percent chance of snow this afternoon and evening, and the high is expected to reach 30 degrees, Britt said. Temperatures are expected to rise to the lower 40s on Sunday.
Boyce said he encourages everyone to take precautions during winter storms.
"It's a good idea to have a winter preparedness kit for your car, carry a blanket in your car, and make sure your car is well cared for and winterized," he said.
The Missouri Department of Transportation's Traveler Information Map at traveler.modot.org/map offers updates on the condition of Missouri highways during bad weather conditions. The map can also be downloaded as a free app for Apple and Android devices. MoDOT also provides road condition information through its Customer Service Center at 888-ASK-MODOT.
MoDOT also offered these safety tips for traveling in inclement weather:
Wear your seat belt and don't drive distracted.
Adjust your speed to the conditions. Do not use cruise control.
Keep mirrors, windows and lights clean.
Stay at least six car lengths back from snowplows and equipment. Plowed snow can create a cloud that can blind drivers following too closely.
If your wipers are on, keep your headlights on. It's the law.
If you encounter car troubles or are involved in a crash, remain in your vehicle.
