Freezing rain and light snow are expected to begin at about 6 p.m. Tuesday, lasting into Wednesday and complicating the Wednesday morning commute, according to the St. Louis County Office of Emergency Management.
Total accumulation is only expected to be half an inch of snow and 1/10 inch of ice. However, it is enough to make roads slippery, and drivers are urged to slow down and use caution.

High temperature is predicted at 30 degrees, with an overnight low of 20 degrees with 60 percent chance of precipitation.
