A supercell thunderstorm developed east of Lusk, WY near 2PM MDT on
7 June 2022 north of Highway 20 that exhibited broad rotation from
KCYS radar. This rotation tightened near 2:20pm MDT just north of
Highway 20 west-northwest of Duck Creek Ranch. First indications of
ground damage start at west side of Duck Creek Ranch with wood fencing
blown down. The tornado intensified and widened as it approached 
Duck Creek Ranch with metal sheeting fencing pulled from metal 
posts and roof damage occurring on a large ranch shed. A 
convergent damage pattern was apparent with the debris of the wood
fencing being blown west and the solid sheet metal fencing blown 
north and bent backwards to the west with the roof damage facing 
south. Hardwood trees were snapped at the base along with softwood
pines both snapped and uprooted in proximity to a single family 
home. The snapped pine tree and the uprooted pine tree were facing
opposite directions. The more impressive damage was a barn roof 
and partial second level were torn off and thrown 50 to 100 yards 
to the southeast. Additional tin roof peeling damage was noted on 
another farm building and a large side sheet metal and wood 
section on the southern end of the tornado path was torn from the 
facade. Duck Creek Ranch is where the more intense damage was 
noted. Farther southeast along, Highway 20, sporadic pockets of 
cattle windbreak fencing damage was noted near a WYDOT road sensor
that gusted to 78mph during this time frame. Lastly, near mile 
marker 59 on Highway 20, four (4) power poles were leaning south 
and marks the end of the tornado path. No additional damage was 
seen or reported in Van Tassell and along South Van Tassell Road.
