A severe thunderstorm was set to bring golf-ball sized hail, damaging winds and possibly tornadoes to Texas and parts of the South on Wednesday, according to forecasters.
The greatest chance of twisters will be in and around Dallas, as well as other parts of northeast Texas and southern Oklahoma, Weather Channel lead meteorologist Kevin Roth said.
Accompanying the tornado threat will likely be two-inch hail — larger than the size of a golf ball — and strong winds that have the potential to damage buildings, Roth added.
The storm — which will build Wednesday afternoon in northwest and southern Oklahoma — was expected to roll into Arkansas and Louisiana, where the tornado threat will be significantly lower, later Wednesday night.
"The whole storm system will be with us through Saturday," Roth said, predicting a lull on Thursday before the storm picked back up in Mississippi, Alabama, Tennessee, Georgia and Florida on Friday.
"It's too early to tell how severe that round will be and whether there will be tornado threats," he added.
Meanwhile, a cold air mass was covering the Great Lakes, Midwest and parts of the Plains on Wednesday, with temperatures 5 to 20 degrees below average. On Thursday this was set to expand to the Northeast where it was expected to bring similarly chilly conditions.
