A long-lived supercell thunderstorm formed over northwest Rockingham County during the afternoon of the 28th. This severe storm moved east at 45 MPH, damaging property all of the way to the Potomac River. This same storm later produced a devastating F4 tornado in La Plata, MD. While the storm moved through North Central Virginia, it produced an F2 tornado in Shenandoah County, a significant funnel cloud in Fauquier County, large hail, heavy downpours, and scattered wind damage. In Shenandoah County, an F2 tornado touched down just east of Quicksburg near the intersection of Quicksburg Road and Old Bridge Road. The tornado stayed on the ground for 4 miles before it dissipated while moving up the west side of Massanutten Mountain. The twister was estimated to be about 75 yards wide and it caused a total of $1.6 million in damage. Along the path of the tornado, three residential structures were destroyed, 12 structures were heavily damaged, and 15 had minor damage. Four poultry houses and 15 barns were destroyed. Five poultry houses, two silos, and a mile of fencing was also damaged. On Old Bridge Road, a silo and three barns were damaged.

The tornado moved across I-81 and Route 11 into the Kay Hill subdivision. Homes were damaged and trees were downed on Lower and Upper Forge Road. A mobile home on Mantz Drive was destroyed.
