Not sure where you're coming from, but be cautious traversing the midwest. We are already under a Winter Storm warning here in St. Louis, and Chicago is probably under the gun too.
EDIT: I checked the forecast for Chicago, and it has snow every day, 1-2 inches tonight, 4-6 inches expected Thursday morning, and another 2-4 inches Thursday night. Also very cold temperatures are expected.
I know Kansas City has a lot of snow. Not sure what airports are doing yet.
I do know the snow is supposed to stop here Thursday morning, maybe you could wait till the storm ends? I think driving would be the safer bet, but it's your call.
Either way, I'll pray for you to have a safe trip.
