Oklahoma tornado warning issued

NORMAN, Okla. (AP) - Storms are moving through Oklahoma, Arkansas and other parts of the central U.S., and forecasters say tornadoes are possible.

The Storm Prediction Center in Norman, Okla., warns there's a moderate risk of severe weather over much of eastern and central Oklahoma on Thursday - the same area where a tornado last week killed 24 people in Moore.

Tornado warnings were issued in parts of Oklahoma and Arkansas Thursday afternoon. Storms could produce 3-inch hail and some tornadoes, some of which could be significant. When storms form, they will generally move eastward.

Weather could worsen later in parts of Kansas and Missouri.

Storms are also possible in the mid-Mississippi Valley and into the Upper Midwest

There is also a moderate risk for storms Friday in much of the same area.
