Weather and flood threats increase into holiday weekend. Any pause in storminess after the week-long barrage that ended Wednesday is short-lived, as severe weather and flood threats increase into Memorial Day weekend across a big chunk of the south-central United States.

Thunderstorms are expected to impact several regions across the country on Memorial Day weekend making it harder to travel in the air and on the ground.

The Memorial Day weekend kicked off with a multi-day thunderstorm and heavy rainfall system hitting the south-central part of the country, forecasters said.
