I honestly am not sure.
I have never tracked anything like this that ships via air. Normally packages for our house go through Hodgekins IL, then take a truck to Bloomington, IL, and are out from delivery form there.
It will be interesting to see how the routing happens since it sounds like the package will go from Louisville to Rockford. Surely the package will still route through the Bloomington location? I think the package can get to Rockford in enough time, but I do not believe that it will make it to Bloomington in enough time to go out for delivery tomorrow morning.
I hope UPS proves me wrong though.

Look at the flight tracks. Flight plan has them flying into the continental US and then are flying east to get around the storms. lol
