STERLING, Neb. -- Severe storms moved through southeast Nebraska Thursday morning, prompting severe thunderstorm warnings for a while in the KFOR listening area. As storms rumbled through Sterling in northwestern Johnson County, about a half-hour southeast of Lincoln, weather spotters reported an estimated 70 mph wind gust, with some tree damage and power lines down. Terri Bartels, who is a bookkeeper for Sterling Public Schools, tells KFOR News they experience high winds, heavy rain and the electricity flickered. Johnson County Emergency Management director Clint Strayhorn confirmed to KFOR News there is tree damage in town. At one point, state highway 41 was blocked off on the north side of town. Strayhorn says NPPD crews were working on restoring power in some areas of town. No one was hurt.
