Storms are moving through Oklahoma 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. That is the same area where a tornado last week killed 24 people in Moore.

Weather could worsen later in parts of Arkansas, Kansas and Missouri.

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

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.
