Snow and sleet fell from late morning into the mid-afternoon for areas west and north of St. Louis with rain and a little sleet farther east and southeast into St. Louis. The heaviest precipitation has moved northeast away from the metro area in time for the Wednesday evening rush hour.

The 5 On Your Side weather team said the additional light wintry mix of snow, freezing rain and rain will not create major problems overnight as temperatures drop into the mid and upper 20s. Elevated and untreated surfaces will be more likely to be slick or icy.

How crews prepared:

Illinois Department of Transportation: IDOT reports its crews were already out Tuesday night treating spots in the northern parts of its district, and it plans to continue treatment as the storm moves in.

Missouri Department of Transportation: MoDOT crews were out monitoring conditions Tuesday night. 

City of St. Louis: St. Louis City crews started 12-hour shifts at midnight Wednesday. The city did not pretreat roads because the storm began as rain, which can wash away any treatment.

St. Louis County: St. Louis County plans to bring in its overnight crews at 11 p.m. Tuesday. The county will start by monitoring bridges because they tend to freeze first. At 2 a.m. Wednesday, the county said it plans to treat neighborhood streets. By 7 a.m., it'll transition to treating the main roads.
