Severe thunderstorms are defined as those with wind gusts of 58 MPH or greater, hail at least 1.00" in diameter or larger, or producing a tornado, while regular thunderstorms can still produce hail and gusty winds but do not meet these thresholds.

More than 40 million Americans are in the threat zone through Saturday night, stretching from Texas to the Carolinas.

Sunday night’s thunderstorms knocked out power to tens of thousands of people across North Texas, brought winds over 50 miles per hour and dropped 1-3 inches of rain. The storms, while strong, were not quite as intense as some forecasts originally suggested.

One of the hardest-hit places was Bonham, where wind and rain caused trees to hit homes and power lines all over town.

Severe weather hit northern Texas and southern Oklahoma this weekend, leaving thousands of residents without power. The storms included tornadoes, hail and wind gusts over 80 mph.

Storms are expected to fire off in northwest Oklahoma by 2 a.m. Saturday and continue to track into the Oklahoma City metro by 6 a.m. Saturday. The main threats with storms are damaging wind gusts, up to 70 mph. Be sure to download the KOCO 5 App to receive customized weather alerts. You can watch our team coverage on the app, too.
