What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

An NWS survey concluded that a small EF-1 tornado touched down in Millwood within a larger area of straight-line wind damage. Maximum winds were estimated to be 90 mph. In the Carter Hall area of Millwood, nearly all of the trees in one strand were uprooted or snapped and fell in nearly every direction.

The wider storm

A stalled front resided across the Mid Atlantic during the afternoon and evening of June 4th, allowing moisture and instability to pool along the boundary. This combined with several strong upper level disturbances resulted in numerous thunderstorms during the afternoon and evening. Many of these thunderstorms became severe. While penny sized was reported in spots, damaging winds from the thunderstorms was widespread. EF-1 tornadoes were confirmed near Stevensville in Culpeper County, in Millwood in Clarke County and near Hartwood in Stafford County.

Began near Millwood (39.0700, -78.0400).
