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.

Temperatures will be spilt across the country over the holiday weekend with cool temperatures in the Northeast and Midwest and warm temperatures across the western and southern U.S. Meanwhile, rounds of severe weather and heavy rain are expected across the Plains and parts of the South.

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.
