Severe storms and hail threaten southern US.

Parts of Texas and the South are under threat from severe storms, including tornadoes, large hail, and damaging winds, due to an unusual weather pattern bringing a stronger-than-average jet stream from the Pacific Ocean. The multiday threat of severe weather is expected to continue throughout the week, with flash flooding likely in many areas due to days of heavy rain. The severe storm threat shifts to the Southeast on Wednesday and Thursday, with damaging wind gusts and large hail expected to be the primary threats.
