Here is the latest radar (7:30pm) showing an increasing area of freezing rain -- along with lightning -- developing over the Ozarks.
A reliable computer model is indicating there could be heavy ice accumulations in places.
For my readers in the Wichita area, note that 0.02" of freezing rain is forecast to fall late tonight to noon Wednesday. That is more than the amount that caused all of the traffic problems this morning.
An ice storm warning (purple) is also in effect farther north across northern Illinois, including Chicago.
