Severe thunderstorms are already firing up west and northwest of Fort Worth capable of producing strong winds and quarter-size hail.
A tornado watch has issued until 8 p.m. Wednesday that includes, Tarrant, Dallas, Parker, Hood, Johnson, Ellis and Denton counties.
Storms are expected to arrive in Tarrant County later Wednesday. A flash flood watch is in effect until Thursday morning for most of North Texas with 2- to 3- inch rainfalls possible.
“It’s definitely one of those days where you want to have a reliable weather source,” said National Weather Service meteorologist Juan Hernandez.
Hernandez said forecasters are worried that storms could “train” over some areas bringing repeated rounds of heavy rain for several hours.
The Storm Prediction Center has the Dallas-Fort Worth area under an enhanced risk of storms (3 on a scale of 5).
Damaging winds, large hail and some tornadoes are all possible.
“A semi-focused risk for tornadoes appears to exist within a corridor from north-central/northeast Texas and southeast Oklahoma into west/southwest Arkansas,” the Storm Prediction Center forecast said. “Additionally, very large hail will be possible, along with a continued risk for locally damaging winds.”
