Plentiful moisture ahead of an approaching weather system brought widespread rainfall to the area Friday night. By Saturday morning the rain and thunderstorms had mostly pushed east into Oklahoma, but the environment over the Texas Panhandle remained very moist. As temperatures warmed and instability increased, thunderstorms intensified and became more numerous. Some of the thunderstorms became severe producing large hail and damaging winds. A supercell thunderstorm moved into Donley County around 12:30 PM CST and spawned three tornadoes as it tracked northeast across Donley, Collingsworth and Wheeler counties. Damage was mostly limited to barns, trees and power poles across rural sections of these counties. However, one home sustained significant roof damage north of Hedley. Isolated EF-1 damage occurred in two tornadoes otherwise damage was consistent with an EF-0 tornado for most of its path.
