Many are bracing a severe snowstorm in the Midwest today. CNN is tracking it for you this morning. Carmen Iacullo is from the Illinois Department of Transportation. He has the latest on conditions during the storm and joins “Early Start” live from Chicago this morning. 

“Right now the temperatures are under freezing,” Iacullo says. “So we’re watching for freeze-back conditions. The fact that the temperatures didn’t decline until after midnight helped out a lot with the snowfall.”

Iacullo warns that travelers need to be careful on the road. “Chicago expressways are still wet and people need to be cautious as freeze-back will occur.” Iacullo adds that there have fortunately been no deadly accidents.
