A closed upper level low moved eastward from Missouri and Arkansas and into Tennessee during the daytime hours of April 19th, and then moved northward into Kentucky during the night. At the surface, low pressure moved from near Tennessee in the morning to eastern Kentucky by the evening, and into Ohio by late in the night, intensifying along its track. This brought strong forcing across the Mid-Atlantic and southeastern United States with divergent flow aloft and deep moist southerly flow at the surface. Moderate instability developed by the afternoon hours with strong speed and directional shear aloft. This led to two distinct rounds of showers and thunderstorms across northern and central Virginia, with the first round in the mid to late afternoon hours, and a second more organized round in the evening that evolved into a quasi-linear convective system. Some of the thunderstorms became severe with locally damaging winds. Two tornadoes were also confirmed, one from a supercell in the late afternoon, and one from the quasi-linear convective system in the late evening.

A tornado produced a discontinuous line of damage along a path approximately four miles long, lasting five minutes through Reston, Virginia. The tornado was rated EF-0, with peak winds of 70 miles per hour and maximum path width of 100 yards. The tornado's storm motion was north-northeast at approximately 50 miles per hour. The damage was primarily uprooted or topped trees. No injuries or fatalities were reported with this tornado.

After passing across the Dulles Toll Road (Virginia State Route 267), minor tree damage was noted between Sunset Hills Road and Baron Cameron Avenue. The tornado then tracked across Reston Hospital Center, with no visible signs of damage, but damage was noted just north of the hospital on Town Center Drive near Town Center Parkway, where a tree was topped, fencing blown down, and shingles blown off several townhouses.
After crossing Baron Cameron Avenue, the tornado passed just east of Trader Joe's grocery store destroying an outdoor shed. Nearby, a tall, two-foot diameter tree crashed through the upper floor of a townhouse on Quietree Drive that led local officials to condemn the property. Several large trees were either uprooted or topped along Bennington Woods Road between Crosswind Drive and Reston Parkway. A large, 100-foot tall tree fell and smashed the front end of an unoccupied vehicle parked along Center Harbor Road, midway between Reston Parkway and North Village Road. Minor tree damage along a narrow path was noted in neighborhoods located between North Village Road and Reston Parkway between Center Harbor Road and Wiehle Avenue. No substantial storm damage was noted north of Wiehle Avenue, where the tornado weakened and lifted at 9:00 PM EDT (8:00 PM EST).

Location: ELMA
Tornado F-scale: EF1
Reported by: NWS Storm Survey

A tornado touched down just south of Keys Church Road (Virginia State Route 722) and proceeded north-northeast across Keys Church Road to James River Road. Along this initial phase of the tornado, scattered tree damage was observed in the woods. Multiple trees along this path were snapped about a third of the way up the trunk. A tree was downed towards the southeast over James River Road.
As the tornado continued northeast of James River Road, it intensified and created its most significant damage to two farm properties and adjacent woods. As the width of the circulation expanded to 125 yards, most of the trees within this portion of its path were snapped or uprooted. It is estimated that between 100 and 200 trees were downed in this area. One tree fell and killed a horse. A large tree also fell on three vehicles and a recreational vehicle was blown over. Several small outbuildings and sheds were damaged or destroyed. A resident to the southeast of the tornado captured the funnel in photographs.
The tornado then continued several hundred yards northeast into the forest before dissipating, creating additional widespread tree damage.
