The National Weather Service surveyed damage in Pinson and determined that it was the result of a microburst. Most damage was found along a one-mile swath north to south from Highway 75 near Rudd School Rd to near Silver Lake Rd and Pine St. In this area, approximately 1,000 yards wide east to west, numerous trees were uprooted, falling on homes and power lines. Up to 15 homes were estimated to have been damaged, mainly by falling trees, with five homes sustaining moderate damage along Cobblestone Ct. Other streets with trees on homes included Church St, Silver Lake Rd, and Echo Dr. Also of note were numerous trees downed in a large cemetery, along with heavy timber damage in a swampy area between Highway 75 and Bud Holmes Rd. Most of the treefall was observed to have been south or southwest, although depending on the exact location relative to the microburst, some trees and debris were blown in various directions. This damage was the result of a rapidly descending thunderstorm core, associated with an ensuing hail storm in Pinson. Winds were estimated at 70-75 mph. The NWS would like to thank Jefferson County EMA for their assistance during this survey.

The National Weather Service surveyed damage in Trussville and determined that a high-end EF-0 tornado occurred. Damage began along the north end of Mary Taylor Rd, where a construction trailer was flipped. A portion of the Metro Mini Storage had doors blown in and metal roofing lifted/peeled back. Next to this, approximately 13-14 trees in close proximity were uprooted, including 12 cedar trees in a tight row. Winds were estimated at about 80 mph here. The tornado crossed Highway 11, where minor roof damage was done to a car wash and Velma's
restaurant. As the tornado moved southeastward along Mary Taylor Rd, large doors were partially blown in and roofing was removed from a warehouse, and a fence was damaged at a dog daycare center. The tornado crossed a railroad and struck Daniel Iron, with a section of a warehouse having large doors blown in and large
pieces of metal roofing removed. A few flatbed semi trailers were moved in the lot as well.

The tornado then ascended a small ridge and moved through a subdivision, causing mainly shingle and fence damage at numerous homes, along with a few trees and limbs being downed. At least one home was observed to have had a garage door damaged. Of particular note was the discovery of a large chunk of steel roofing from the Daniel Iron warehouse that landed on a home before sliding off and coming to rest on the side of another home.
This caused considerable roof damage to the first home, resulting in water damage from rain. After this, minor tree and shingle damage continued across Hidden Brook Dr, Amber Trace, Yvonne St, and Alabama Dr, with the most notable damage being a few uprooted trees in close proximity along Yvonne St. The last area of discernible damage, very minor in nature, was observed near a lake in a curve along Queenstown Rd. Wind speeds at the peak were estimated at 85 mph at Daniel Iron. The NWS would like to thank Jefferson County EMA for their assistance during this survey.
