The emerging storm system will bring with it a roaring streak of wind energy several thousand feet aloft. By Thursday, winds some 20,000 feet above ground level will be screaming from the southwest at 100 to 140 mph from the Texas Panhandle to Minnesota. Winds of 60 mph may be blowing just a few thousand feet above ground level in parts of that corridor. Similar conditions will shift into the Great Lakes region Friday.
That's not just a concern for pilots. As thunderstorms erupt, they could pull some of that wind momentum down to ground level and that would bring the potential for damaging winds. That's the main reason for the severe weather threat areas depicted for Thursday and Friday.
