ST. LOUIS — 5 On Your Side is in Storm Alert as a winter storm moves through Thursday across a large portion of the middle Mississippi River valley.

The first wave of snow, sleet and freezing rain pushed away from St. Louis Wednesday afternoon leaving six to twelve inches of snow over far western portions of the metro area north into the Hannibal, Missouri, area. Across much of the rest of the metro area, the mix of freezing rain and sleet limited snow accumulations, but more snow is expected.

CLOSINGS: Check school districts, churches, senior centers, childcare centers and more for closings or delays

The battle zone continues from Texas to the northeast Thursday as the cold air sags southeast. Another round of significant snow will fall along I-44 in Missouri and east along I-70 into Illinois through Thursday.

Travel impacts are expected over portions of eastern Kansas, Missouri, Illinois and Iowa and into the Great Lakes as the system evolves. Once the system moves away, the arctic chill will linger into through the end of the week with temperatures well below average for early February.
