For Saturday night and early Sunday morning, forecasters are calling for another round of severe storms, damaging wind, renewed flooding and the chance for isolated tornadoes in the Chattanooga region, particularly counties to the west on the Cumberland Plateau.

Depending on how the system develops through the day, storms early on Saturday will be spotty and mostly north of Chattanooga in the afternoon and evening as the temperature tops out in the mid-70s, according to WRCB-TV Channel 3 meteorologist Paul Barys.

"It doesn't look like tornado outbreaks - it's not impossible - but it looks mainly like severe thunderstorms," Barys said of the National Weather Service's Storm Prediction Center outlook.
