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.

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.

A few pop-up showers and storms are possible with around 30 percent coverage. For stronger storms, lightning and gusty winds are the main threats. Memorial Day will be mostly dry through the morning and afternoon. By the evening, a storm complex will try to move in, causing some storms.
