A cut off low over the Midwest pushed a cold front through the Mid Atlantic during the morning hours. Scattered showers with embedded thunderstorms formed along this front in a strong directional and magnitudinal sheared environment. Diurnal heating led to minimal instability. The combination of the strong sheared environment and low CAPE resulted in a weak tornado across Fairfax County and the City of Alexandria.

Tornado in FAIRFAX, VIRGINIA
From 15-OCT-14 11:23:00 to 15-OCT-14 11:25:00 (EST-5)
Location: BELLE HAVEN
Tornado F-scale: EF0
Reported by: NWS Storm Survey

After a review of radar observations, the public and broadcast Media reports, the National Weather Service in Baltimore MD/Washington DC has confirmed an EF-0 tornado touched down near Belle Haven in Eastern Fairfax County, Virginia and continued north on an approximate 1.5 mile intermittent damage path to the City of Alexandria before dissipating. This review is based on corroborating evidence of observed damage locations and rotational velocity couplets from the Federal Aviation Administrations Terminal Doppler Weather Radars at Washington Reagan National Airport and Joint Base Andrews, along with National Weather Service KLWX WSR-88D radar in Sterling, VA.
The tornado is estimated to have touched down at 12:23 pm in southeastern Fairfax County, where there was a tree down near the intersection of Hunt Road and Belle Haven Road. The tornado continued north across the Belle Haven Country Club where more large tree limbs were snapped. The tornado then briefly moved into the City of Alexandria, likely lifting across Interstate 495 at the intersection of George Washington Parkway, where large tree branches were also downed. Several more large tree branches were snapped in the immediate adjacent neighborhood to the north before the radar couplet signature weakened after 12:26 pm. Estimated maximum winds were 55-65 mph.
