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 eastern Frederick County MD near Monrovia and New Market. 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 eastern Frederick County MD.
Initial damage was to several structures at a farm in the 11000 block of Fingerboard Road, where a machine shed and barn were flattened. A silo was also heavily damaged. Tree damage was noted near the intersection of State routes 75 and 80. A large swath of tree and utility line damage was noted along Lynn Burke Rd near Old Bartholows Rd just south of I-70.
The tornado crossed I-70 and moved along Jesse Smith Rd where more tree damage (uprooted and topped) was observed. Further north along the 12900 block of Jesse Smith Rd, more significant tree damage occurred with numerous softwood trees topped at two residences along a concentrated damage path.
The tornado continued northeast over open country before crossing Old Annapolis Rd near Ravenwood Rd, producing extensive tree damage at several residences. Finally, the tornado caused tree damage as it crossed Bottom Rd along Woodville Branch and
continued into a wooded area that was not surveyed due to impending darkness.
