The Mid-Atlantic remained in the warm sector as a nearly stalled warm front lingered just north of the Mason-Dixon line and the associated cold front swung in from the west by the evening. The unstable air mass led to SBCAPE values between 2000-3500 J/kg while effective shear values were between 30-40 knots.

A stalled frontal boundary acted as the triggering point for an initial line of showers and thunderstorms, with many of the storms becoming severe with strong moisture advection combining with diurnal heating and leading to an unstable air mass. The remnants of Tropical System Bill moved through the Mid-Atlantic overnight, continuing the severe threat late into the early part of the overnight hours.

A cold front moved south through the region.

Some thunderstorms produced copious amounts of rainfall and led to flooding around the Baltimore and Washington DC metros.

A team from the National Weather Service in Sterling Virginia concluded that a tornado struck southern Charles County just south of the US -301 Bridge at Morgantown.

The tornado peaked at EF-1 intensity with winds of 90 mph produced damage beginning at the Potomac River Shoreline in Morgantown. The tornado moved northeast along Morgantown Road, ending its damage path just after it crossed over Route 257-Rock Point Road.

While on the ground through Morgantown and along Morgantown Road, the tree damage was substantial with dozens of large trees snapped and uprooted in multiple directions along its path. It took several crews hours to remove numerous large trees and restore access down Morgantown Road. Many homes had some of their shingles removed and siding damage, and at least one home had roofing materials removed along the roof edge. More substantial structural damage was mainly limited to destroyed outbuildings and carports, except where trees fell on homes.

The damage coincided with a tornadic signature on National Weather Service and FAA Doppler Radars .

Potent low pressure passed by to our west, and the warm front associated with the low moved through our area during this time. Warm and moist air near and south of the boundary led to an unstable atmosphere, while forcing from the warm front provided the lift. Thunderstorms developed, and with potent shear profiles around the warm front isolated thunderstorms did produce tornadoes.

National Weather Service personnel completed a ground survey along with radar analysis and concluded a small tornado produced damage along a 2.1 mile path beginning near the intersection of Virginia State Route 28/Nokesville road/ and Linton Hall Road. The tornado then moved northeast along Route 28, ending it’s damage path at the baseball fields at the intersection of Godwin road and Route 28.

The tornado’s path width was approximately 100 yards. The bulk of the damage occurred at the Broad Run golf training center where about a half-dozen softwood trees between 12 and 18 inches in diameter were snapped approximately 4 feet above the ground. The damage at the baseball fields at the intersection of Route 28 and Godwin Road included a scoreboard secured by 4x4s being snapped, along with baseball dugout roofs lifted and blown away. The damage was sporadic along the 2.1 mile path, but coincided with the tornadic signature as depicted on WSR-88D and FAA Terminal Doppler weather radar. No additional damage was noted northeast of Godwin road.

A potent upper level disturbance moving through the Great Lakes lifted the associated surface warm front through during the day, eventually stalling near the Mason-Dixon line. In the wake, warm air and moisture advection led to the development of an unstable air mass, with scattered convection forming, including scattered strong to severe thunderstorms.

Multiple trees were down along Trough Goad north of Old Stonehouse Road. Trees were estimated to be around three feet in diameter.

A warm front passed through the area while an upper-level trough approached from the west. A southerly flow behind the front caused an unstable atmosphere, and moderate amounts of instability developed due to colder air aloft ahead of the approaching trough. There was enough instability for an isolated storm to become severe in the Eastern Panhandle.
