A “significant weather outbreak” is expected Friday afternoon through early Saturday from East Texas across the Deep South, according to the National Weather Service.
The weather service says tornadoes and damaging winds are the primary threats in the Longview area and elsewhere, but large hail and isolated flash flooding also are possible.
More than 9 million people live in parts of Texas, Oklahoma, Arkansas and Louisiana where there is an enhanced risk of severe weather Friday, according to the federal Storm Prediction Center.
Winds of up to 70 mph will be possible in parts of Alabama on Saturday, the National Weather Service’s Birmingham office warned.
“All modes of severe weather appear to be in play with this system, including the threat of tornadoes in addition to large hail and damaging winds,” forecasters at the weather service’s Shreveport office said in a briefing on the incoming storm system.
The storm is expected to move eastward Saturday, with the potential bull’s-eye covering millions of people across much of Mississippi and Alabama, plus parts of eastern Louisiana and the Florida Panhandle. Storms could reach as far north as the Ohio Valley.
Heavy rains are possible in addition to damaging winds, according to the Storm Prediction Center. Many streams already are at or near flood levels because of earlier storms.
Temperatures in the Longview area are expected to hit the mid-70s Friday before falling to a low of about 46 Friday night. A high in the lower 50s is forecast Saturday with lows dipping to around 30 Saturday night.
