OKLAHOMA CITY -- Tornado sirens sounded in Oklahoma City early Saturday on what forecasters warned could be a day of "life-threatening" weather in the nation's midsection.
The most dangerous conditions are projected for late Saturday afternoon between Oklahoma City and Salina, Kan.
Forecasters said other areas also could see severe storms with baseball-sized hail and winds of up to 70 mph.
The Storm Prediction Center in Oklahoma said the outbreak could be a "high-end, life-threatening event."
Its warning covers parts of Illinois, Iowa, Kansas, Missouri, Nebraska, Oklahoma and Texas.
Emergency workers focused their attention overnight on central Oklahoma, where they said funnel clouds had been spotted though none had touched down. The area includes the small town of Piedmont, where a twister last May killed several people.
