The Missouri Department of Transportation advised drivers Thursday to stay off the roads over the weekend ahead of a forecast winter storm and below-freezing temperatures.
The below-freezing temperatures may make chemicals that are used to treat roads less effective. Cleanup from the storm may take longer than the previous weekend's, the department warned. Wind gusts could cause drifting.
The city of Columbia warned on Wednesday that the storm could affect travel, power and city services.
The National Weather Service forecast calls for rain and snow on Friday and Saturday. On Sunday, the high is predicted to be 23 degrees.
