A small amount of snow, rain and sleet will freeze on surfaces from parts of Oklahoma to southern Illinois and Indiana on Sunday night into Monday.
Just enough precipitation will fall combined with below-freezing temperatures in the swath from Oklahoma City to Tulsa, Oklahoma; Fort Smith, Arkansas; Springfield and Cape Girardeau, Missouri, and Evansville, Indiana, to make for slippery travel.
The slippery conditions could reach into some of the suburbs around St. Louis as well.
A push of arctic air will cause temperatures to plummet in this swath into Monday as just enough moisture lingers to squeeze out a light wintry mix.
Motorists and pedestrians in this zone are urged to exercise caution as roads, sidewalks and parking lots may appear to be wet, but may, in fact be covered with black (clear) ice.
Elevated surfaces, such as bridges and overpasses may freeze first.
Travel conditions should improve later in the day on Monday as a breeze allows surfaces to dry off and temperatures inch upward into the 30s.
The freeze-up on Sunday night into Monday follows several days of warmth from the Thanksgiving weekend.
As quickly as the cold air moves in early this week, it will leave by midweek with temperatures forecast to rebound later on Tuesday and Wednesday.
