Episode Narrative Cutoff low pressure was over the Ohio Valley. Another area of low pressure strengthened overhead on the occluded boundary. Warm and moist air from the south lead to an unstable atmosphere. Strong shear profiles were in place due to the cutoff low to the west. Strong lift associated with the developing low combined with strong shear and enough instability to produce severe thunderstorms and isolated tornadoes.
Event Narrative A path of sporadic damage, mainly to trees, began just east of Rock Hill Road in between the Dulles Greene and Capstone apartment complexes in Herndon. About a half dozen trees here were either snapped or uprooted in a convergent pattern. One of the trees was thrown into the window of a nearby apartment building.
The National Weather Service would like to thank Fairfax and Loudoun County Emergency Management Agency and the residents interviewed for their assistance in this survey.
The tornado continued north-northeast, where additional tree damage was noted near the intersections of Summerfield Drive and Autumn Breeze Court, and Sterling Road (VA-606) and Herndon Parkway. Several trees were downed from east to west, and fencing was blown down north to south.
It appears the tornado lifted briefly as it continued north-northeast, before touching down again near the intersection of Crestview Drive and Builders Road. Here, nearly a dozen trees were snapped or uprooted, mainly to the north, with fencing blown down towards the trees (to the west).
