Holiday travelers returning home this weekend could contend with more delays at airports as severe thunderstorms intensify and tornadoes break out in the South and a parade of atmospheric river-fueled storms slams the West.

Severe thunderstorms are firing up in parts of Texas and could trigger high winds, hail and potential tornadoes.

Possible thunderstorms could bring isolated tornadoes into Saturday night in Tennessee, Texas, Louisiana, and Georgia, according to media forecasting company AccuWeather. It said that showers with thunder and lightning may move toward the Southeast and mid-Atlantic by the weekend’s end.
