It would not hurt to stay up later than normal Saturday or to turn up the volume for your weather alerts so that you wake up if a tornado watch or warning is issued for your area. Have a weather safety plan in place, as the severe storm threat will linger into early Sunday.

A widespread and dangerous severe weather outbreak is expected to develop Friday and into the weekend as a powerful storm system unleashes its fury across the central and eastern U.S., impacting more than 150 million people.

There is a threat of tornadoes at night, so residents in at-risk areas are advised to set their phones to receive loud weather warnings which will wake them up.
