The second line of storms that passed through here this afternoon also caused problems thousands of feet up.

At least two people were injured after turbulence forced a plane to make an emergency landing in Louisville.

It happened at the Louisville International Airport just after 6 p.m., when ambulances took a flight attendant from the Northwest flight to a local hospital.

The flight left Knoxville around 4:30 p.m. headed to Detroit.  About 35 miles outside of Louisville the plane experienced "heavy turbulence" caused by storms in the area.

A flight attendant and a passenger were injured, but their injuries do not appear to be serious.  The remaining passengers were placed on other flights.
