LIVE: Tornado Touches Down in South Dakota

After Saturday's violent thunderstorms, a new round of severe weather will threaten lives, property and Mother's Day festivities across the Plains on Sunday.

The majority of the thunderstorms that targeted central Texas and Oklahoma earlier Saturday morning unleashed torrential rainfall. Only a handful of thunderstorms turned severe with damaging winds and/or hail.

Now that the sun has had an opportunity to warm and destabilize the atmosphere, the number of severe thunderstorms will increase through Saturday afternoon from around Iowa and Missouri to northeastern Texas.

The strongest thunderstorms on this Mother's Day will be capable of producing damaging winds, large hail, frequent lightning and blinding downpours. A couple of tornadoes will also touch down and cause destruction.
