An extremely strong and destructive line of tornado-producing thunderstorms passed through the midwest and midsouth today (March 2).  The storms hit southern Indiana the hardest.  The town of Marysville, about 20 north of Louisville, KY, was described by the Clark County sheriff as 'completely gone.'

Asked on NBC Nightly News if metorologist Jim Cantore could remember an outbreak like this, he compared it to the Super Outbreak of 1974.
