The National Weather Service is warning of new flooding across much of Oklahoma, where creeks, rivers and lakes remain swollen from spring showers. Meteorologist Michael Scotten, in Norman, says two bouts of bad weather should hit the state Thursday. Morning rainfall will likely dwindle before noon, but a system moving in after 2 p.m. could spawn thunderstorms, hail and tornadoes. Some parts of the state could see as much as 3 inches of rain. The greatest threat for severe weather this afternoon is in western Oklahoma, where tennis ball sized hail and tornadoes are possible.
