The metro-east and greater St. Louis area are under a winter storm warning for Saturday evening into Sunday.
The National Weather Service issued a winter storm warning for sleet, freezing rain and snow from 6 p.m. Saturday through 6 a.m. Monday.
The freezing rain and sleet is expected to begin Saturday evening and continue through Sunday before changing over to all snow Sunday evening. Snow and sleet accumulation is expected to be between 4 and 7 inches along with one-tenth to two-tenths of an inch of ice.
The sleet and snow will create hazardous travel conditions Saturday into Sunday across Southern Illinois.
In addition, ice may cause damage to trees and overhead lines, possibly disrupting power and telephone services, the National Weather Service warned.
