Tornado ‘Outbreak’ to Hit Midwest

A tornado hit Norman, Okla. Friday and meteorologists predict an outbreak across the Central and Southern plains this weekend. Norman, where the University of Oklahoma is located, reported no serious injuries, though there was damage to buildings in the town. Areas of Nebraska, Iowa, Kansas and Oklahoma are at high risk, while the threqat is moderate in sections of Texas and Missouri, experts say. Five National Weather Service offices have been working on an "impact based" warning test to convey risks from severe weather and avoid another disaster like Joplin, Missouri, where a storm killed 158.
