On Monday, The Missouri Department of Transportation encouraged drivers to be aware of changing road conditions. They noted that crews will be out on Tuesday night as the rain turns to snow.

“We are expecting a very heavy, wet snow which is great for making snowmen but can make roads very difficult to drive on," said Becky Allermoth, chief safety and operations officer at MoDOT. "If you must be out, adjust your speed to the road conditions.”

Officials in O'Fallon, Illinois are reminding motorists to remove vehicles and obstructions from snow route streets, ahead of this week's winter storm. Failing to do so could result in vehicles being blocked in by plow berms. Also, streets not on emergency snow routes could only be plowed if the depth reaches 4 inches of snow accumulation or more.
