Go-to weather guide: Everything you need to know about closings, traffic and when the snow will stop

ST. LOUIS — A winter storm warning is in effect for most of the St. Louis area through 12 a.m.

When will it stop?

The 5 On Your Side weather team said temperatures Monday night will be in the teens to near 20, so refreezing on area roads, sidewalks and bridges is expected, which could make for another messy commute Tuesday morning.

Tuesday will be calmer, with temperatures in the lower 30s. Expect a slow thaw by the end of the week as temperatures climb to near 50.

Travel

The Missouri Department of Transportation is urging motorists to use extreme caution on their evening commutes.

Forecasts of additional ice and snow throughout the day could make travel hazardous. The system is expected to make its way out of the state overnight but watch for refreezing, particularly on bridges and overpasses.

If you must travel, please allow extra time to reach your destination. MoDOT wants to remind people that even a trace of freezing precipitation can cause slippery roads.

Highways in the Metro East became snow-covered as the storm intensified, the Illinois Department of Transportation said. As the day went on, however, the highways were cleared while side streets remained treacherous.

'Please use extra caution should you be traveling today. And, please don't crowd the plow,' IDOT said on Twitter.
