Our focus now turns to the potential of record lows tonight. Many areas may wake up to thermometer readings below zero.
Interstate 75 was a mess in Rockcastle County Thursday morning.

The semi went across the median at the 62 mile marker and has ended up overturned in the southbound lanes.
It lost its load of lumber.
All lanes are now open.
The semi's driver was the only one injured in the accidents.
He has minor injuries.
