According to the NWS, the tornado first touched down four miles west-southwest of Jarrell at 8:46 p.m. Monday, then touched down two miles south-southwest of Jarrell at 8:53 p.m. It was on the ground for just seven minutes.

The damage path begins west of Interstate 35, just west of CR 234 and north of CR 239. In this area, surveyors observed EF-0 damage to trees and a barn. The tornado also collapsed a two-story home that was under construction near CR 310 and CR 237. As the tornado turned east at that point, it began to strengthen and expand. High grade EF-0 damage was observed to trees and some homes just west of I-35.

The NWS said the tornado then crossed I-35 south of CR 314 and north of Ronald Reagan Boulevard, strengthening further. A semi was overturned on I-35 and the driver suffered minor injuries – the only injuries from this storm. Nine wooden utility poles were downed on the northbound side of I-35, including one snapped in half.

EF-1 damage was observed just east of I-35 and west of Little Road, where more power poles were damaged and broken. A house there suffered roof damage and many large diameter tree limbs were broken. Part of a barn roof was completely removed and a small cargo trailer was lifted 100 yards downwind. This is where maximum sustained winds of 100 mph are estimated.

The tornado then quickly dissipated east of Little Road. Minor wind damage was observed to the east of this area, although this damage was consistent with straight-line thunderstorms as opposed to tornadoes.

It is important to note that a separate area of ​​wind damage was observed further north of the tornado. These were straight-line thunderstorms, as opposed to tornadic winds.

Near CR 313, multiple homes and businesses sustained minor roof damage east of I-35 on both sides of CR 313. Many fences were down in that area and firehouse doors were broken.

The garage door of another business on the west side of I-35 in that area was blown off, and another trailer overturned on the I-35 main road. All of this damage was in a west-to-east orientation, consistent with strong westerly wind gusts from the nontornadic portion of the thunderstorm. Winds in this area are estimated at 60-80 mph.
