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.

A large area of severe thunderstorms is forecast into Tuesday night and will overlap areas in the Ohio, Tennessee and middle Mississippi valleys that were hit by deadly and damaging storms, forecasters say.

North Texas will experience mostly dry weather through the weekend, but conditions will change Sunday night into Memorial Day as a frontal system moves in, bringing a risk of severe storms.
