| Episode Narrative | An area of low pressure formed over the area in response to an impressive longwave trough approaching from the west. A line of low-topped showers and thunderstorms formed along the system's cold front, leading to the formation of multiple tornadoes within the high shear-low CAPE environment. These tornadoes, along with straight-line winds from other storms, produced widespread damage across much of central and northern Maryland. |
| Event Narrative | Staff from NOAA's National Weather Service Baltimore/Washington Weather Forecast Office located in Sterling, VA performed a survey of storm damage that occurred in western Montgomery County MD near Dickerson. This survey, coupled with radar analysis from the KLWX WSR-88D radar and an FAA Terminal Doppler Weather Radar (TIAD), concluded that a tornado rated EF1 on the Enhanced Fujita Scale impacted portions of extreme western Montgomery County MD near Dickerson. Initial damage was noted in trees just west of a farm near the Potomac River off Martinsburg Road. A large barn used to house horses lost all of its roof while an adjacent open-air pole barn was flattened. Several small outbuildings were destroyed. Bleachers at a horse showing facility were overturned. A metal frame windmill tower was toppled. Numerous trees, both hardwood and softwood, were either uprooted or snapped. Then the tornado moved northeast across open fields. It then crossed Martinsburg Rd near a farmhouse where several large trees were uprooted and a farmhouse lost many shingles. No damage was noted past the farm house. This tornado was not the same one that struck near Leesburg, VA earlier. Rather it was a short-lived tornado that spun up quickly to the northeast of the circulation that spawned the Leesburg, VA EF0 tornado. |
