OKLAHOMA CITY (AP) - National Weather Service meteorologists say it's unclear how many tornadoes touched down Friday evening.
Dozens of tornado warnings were issued across a wide swath of the Midwest, including Oklahoma and Missouri, as a large storm front moved through the region. Nine died and dozens were injured.
Weather service meteorologists said Saturday that crews have to assess the damage before determining whether it was caused by tornadoes or severe thunderstorms. Cars were toppled on an interstate in the Oklahoma City area, and aerial images showed damaged to homes and businesses in the suburbs of St. Louis.
They said they expected to have an estimate by Saturday afternoon.
A cold front will move through the Plains and Midwest today, lessening the chances for severe weather.
