Thunderstorms leave damage, power outages in their wake as they roll across Dallas-Fort Worth

After Dallas-Fort Worth hits its highest temperature of the year Monday afternoon, a line of severe weather moved through the region in the evening.

The temperature at DFW International Airport reached 90 degrees just before 3 p.m. — 10 degrees above the average high for the day. But a strong cold front moving through North Texas on Monday evening brought severe thunderstorms along with it.

Thunderstorms began developing on the western edge of Dallas-Fort Worth area shortly after 5 p.m. and moved slowly eastward throughout the evening. Large hail and strong winds were reported across the region.

Storm spotters said a tornado formed in Granbury shortly after 6 p.m. Another was spotted near the Johnson County-Hill County line about 7:30 p.m.

Rick Mitchell, chief meteorologist for KXAS-TV (NBC5), said that a tornado may have crossed southbound Interstate 35E near Johnston Road south of Waxahachie. Video showed multiple tractor-trailers on their sides on the highway, and Ellis County officials said multiple people had been taken to hospitals.

Oncor reported power outages affecting about 10,000 customers in North Texas around 10 p.m.

The weather service issued a tornado watch for most of North Texas, including Dallas, Collin, Denton, Rockwall and Tarrant counties. The watch was set to expire at 11 p.m.
