Northwest Airlines Encounters Turbulence over Kentucky

What: Northwest Airlines( Pinnacle) Canadair CRJ-200 en route from Knoxville,TN to Detroit
Where: Louisville
When: Aug 4th 2009 6 p.m
Who: 24 passengers
Why: Half an hour into the flight, the plane encountered turbulence which injured a flight attendant and a passenger. About twenty-five minutes later, the flight landed in Louisville KY where the flight attendant was hospitalized with minor injuries. The passenger received cuts and bruises which were categorized as not serious. The turbulence the flight encountered was attributed to the same storm system that was behind thunderstorms and flooding in the Kentucky area.

The rest of the passengers were placed on another flight out of Louisville.

Is it possible that pilots and airlines should actually avoid flying during severe weather conditions? I know it is an audacious thing to suggest. Human beings would much prefer to assert dominion over all things natural than to do something that would require a little common sense, especially if it would mean we actually had to wait an hour before taking off.
