One tornado swirled through fields near El Campo, Texas, on Thursday, about midway between Houston and Victoria. Another twister touched down near Atascocita in Harris County, then moved over Lake Houston.

A swath of severe weather spawned multiple tornadoes in southeastern Texas Thursday, part of a multi-day severe weather threat sweeping across the South through the end of the week.

Thursday is a First Alert Weather Day due to the threat of widespread heavy rain and strong to severe storms. Scattered showers are expected to develop in the western counties around sunrise and will move eastward throughout the morning.
