...Summary...
A tornado touched down along Maryland State Route 313 at 3:13 PM 
just south of the Caroline-Queen Anne’s County border. Damage was 
sparse in this area, but a velocity couplet developed over this 
location when viewed by the nearby NEXRAD KDOX in Dover Delaware. 
There was also a small area of low correlation coefficient values 
coinciding this velocity couplet, suggestive of a tornado debris 
signature (TDS). This signature moved in a northeasterly direction 
roughly three to four miles northwest of the small town of 
Henderson, MD. Two areas of damage occurred along this linear path 
created by the TDS, the first being to a residence along Trunk Line 
Road just to the east of the intersection with Taylor Road. Here, a 
small horse barn was completely destroyed, with its roof being blown 
across a yard into a nearby house and several sides falling down. 
This resulted in damage to the roof, siding, and chimney of the 
home. Several trees and branches were also uprooted and broken in 
the vicinity. No damage was reported for roughly 1.4 miles as the 
tornado moved to the northeast, with the base perhaps lifting at 
times. A second area of damage occurred at a chicken farm on Shults 
Road between the intersections with Hecht and Zion Roads. Here, two 
barns were destroyed with the roof being lifted and tossed off of 
one and peeled back and twisted on the second. It is unclear if any 
damage occurred to the chicken barns that were located behind these 
two barns or to any of the poultry. From there, the TDS continued
northeastward for another 1.4 miles before disappearing right 
before the Delaware Border just south of the small town of 
Templeville, MD in Caroline County. It is at this point that we 
estimate the tornado to have lifted based on trends in the 
corresponding velocity couplet and TDS from radar. The NWS survey 
team would like to thank the Marydel Volunteer Fire Company for 
their assistance in this survey, which was conducted remotely and 
is subject to change if additional information becomes available.

EF Scale: The Enhanced Fujita Scale classifies tornadoes into the
following categories:

EF0...Weak......65 to 85 mph
EF1...Weak......86 to 110 mph
EF2...Strong....111 to 135 mph
EF3...Strong....136 to 165 mph
EF4...Violent...166 to 200 mph
EF5...Violent...>200 mph

* The information in this statement is preliminary and subject to
change pending final review of the event and publication in NWS
Storm Data.
