US braced for powerful tornadoes and grapefruit-sized hail

A large storm capable of producing "significant" tornadoes and grapefruit-sized hail could be heading for north Texas, forecasters said.
The most dangerous weather - heavy winds, tornadoes and giant hail - are likely to take aim at a 102,000sq mile area stretching from central Texas to southern Nebraska, including the Dallas, Oklahoma City and Wichita, Kansas, areas, according to the Storm Prediction Centre in Oklahoma.
