National Weather Service meteorologists surveyed damage across far northeast Jefferson County and southern Blount County. It has been determined that the damage was consistent with a tornado. Winds were estimated at 135 mph. A tornado developed along a Quasi-Linear Convective System. It touched down in far northern Jefferson County, northeast of Warrior, and tracked northeastward into Blount County and across the western bank of Mountain Woods Lake before it lifted northeast of Sagefield Rd. The damage along the Jefferson County portion of the track was consistent with an EF1 rating with winds of 95 mph. The tornado touched down east of Old Hayden Rd, and tracked northeast where it downed dozens of trees along Mabel Dr. This resulted in damage to several homes. The tornado moved into Blount County near Sibleyville Rd.

As the tornado moved into Blount County near Sibleyville Rd, it intensified to an EF2 rating with winds of 135 mph. An outbuilding was destroyed and many trees downed near the county line. The tornado continued northeast, before it made a slight eastward turn and moved along the western edge of Mountain Woods Lake. Along the lake, twenty to twenty-five homes were damaged with at least 3 homes destroyed. Three injuries occurred while a family was sheltered in their home, which was destroyed. In addition, multiple boat docks and garages were damaged or destroyed. Along the portion of the path in Blount County, hundreds of trees were snapped or uprooted.
