Madison County, AL (Huntsville)
Rating EF-2 Peak Wind 115 mph
Path Length 6.6 miles Peak Path Width 150 yards

At 5:17 PM CST, a tornado first touched down in a residential development on Redstone Arsenal just north of Goss Rd.  A narrow tornado uprooted a large tree, then prodeeded into a residential area along Magnolia Circle. In this location the tornado tore shingles off roofs and ripped siding off several homes. The tornado then lifted briefly before touching down again near the intersection of Triana Blvd and 9th Ave in Huntsville. From there, it proceeded northeast for 4.4 miles, through Old Town and the Five Points area before lifting near the intersection of Gaboury Ln and Rosalie Ridge Rd near Chapman Mountain. Along the way, many hard and softwood trees were snapped, as were several wooden utility poles. Multiple well-built single family homes sustained substantial roof damage, both from tornadic winds and fallen trees.
