At least one person was killed as tornadoes and severe storms swept through northeast Oklahoma Wednesday evening.

One person was killed and several others injured at a mobile home park in Sand Springs, about seven miles west of Tulsa, after a possible tornado formed nearby, said the Tulsa County Sheriff's Office. Some 36,500 power outages had been reported in northeast Oklahoma as of 3:30 a.m. Thursday morning local time.

Another possible tornado briefly touched down in Moore, about 11 miles south of Oklahoma City, reports KOCO. A radio tower was toppled and a few roofs were taken off homes, but no injuries were immediately reported, said a spokesperson for the city. School was cancelled Thursday because of damage across the district, Moore Public Schools said on its Facebook page.

The Storm Prediction Center warned that a clash of warm and cooler air masses could lead to severe storms. The storms produced at least one tornado, heavy rain and half-dollar size hail.
