Some light ice accumulations can be expected especially on elevated surfaces such as bridges and overpasses. A second and more significant round of winter precipitation is expected late Saturday night through Sunday night. Sleet is expected to occur northwest of a line from Canton to Temple. Sleet may be heavy and accumulate northwest of paris Paris to Dallas to Lampasas line where temperatures should drop to near freezing. Significant icing conditions are possible northwest of a Gainesville-Weatherford-Comanche line where surface temperatures will be even colder.
