Round two of a three-day severe weather outbreak across the eastern half of the United States is getting ready to unfold across the Midwest this evening and tonight. The atmosphere is getting antsy, and it looks primed to produce more destructive straight-line winds and maybe even a strong tornado or two. The storms also have the potential to develop into another derecho, much like the one we saw today.

A dangerous multi-day severe weather outbreak is ramping up across the southern United States at this hour, with a powerful squall line stretching from St. Louis to the Gulf of Mexico. Millions of people are at risk for widespread wind damage, large hail, and even tornadoes.

An incredibly long and impressive line of thunderstorms swept through the central United States on Thursday night, stretching more than 1,200 miles long at its largest extent. The storms left more than 300 of reports of damaging winds and large hail in its wake.
