EF3 tornado in Jack County, Texas

A long track tornado tracked from far southwestern Jack County, through the west side of Jacksboro, and into far southwestern Montague County. The tornado is believed to have begun near Halsell Ranch Rd and Barton Chapel Road where tree damage was observed. The first significant damage noted was on Kinder Mountain Road where the blades of 4 wind turbines were shredded, significant tree damage was observed, and damage to a home and storage barns was observed. The winds were likely EF2 strength in this location. The tornado continued to be tracked to the northeast by observing mostly minor house/roof damage and notable tree damage. As the tornado approached Jacksboro from the southwest it appeared to strengthen and widen. EF2 damage was observed to a secured manufactured home on ONeal Lane and also through the Synterra Estates neighborhood, just south of Highway 380 and west of FM 4. From here, the tornado moved into the western portions of Jacksboro where many homes sustained EF2 damage from Burwick Road all the way to the High School north of Highway 380. The tornado was approximately half a mile wide as it moved through this part of the city. Considerable roof damage and tree damage was observed in this area. Some walls on homes were impacted, and some structures that were not well secured collapsed. The tornado reached EF3 strength as it approached Wichita Avenue and the Jacksboro Elementary School. One well built home on Wichita Avenue suffered very significant roof damage along with other noted damage that indicated winds over 135 mph. From there, the tornado directly struck the elementary school where it ripped the roof off the gymnasium, causing one wall to collapse, bent flag poles to the ground, overturned cars, and more. Continuing to the northeast, the tornado moved through the high school campus, also ripping part of the roof off the high school, damaging the press box at the stadium, bending the field goal posts, bending a light pole to the ground, and more. This damage was determined to be EF2 in strength. Continuing on, the tornado was tracked all the way into far southwestern Montague County by mostly tree damage, damage to metal sheds and outhouses, minor to moderate damage to roofs, and collapsed high tension wire towers. Maximum estimated winds were in the 140-150 mph range. The total length of the tornado was 34.5 miles, accounting for the 0.53 miles the tornado tracked into Montague County (see separate entry).

A strong shortwave trough aided in the development of scattered to numerous thunderstorms during the late morning, afternoon, and evening hours of March 21. Thunderstorms initially fired along a dryline, many of which became severe, and some of which produced strong tornadoes. A total of 17 tornadoes were confirmed by storm survey teams, the strongest of which was the EF-3 Jacksboro tornado. One death occurred in a tornado in Grayson County near the Red River.
