A strong EF-3 tornado touched down near Laramie, Wyoming on June 6, 2018, causing damage to some structures and power lines. There were no injuries reported but the tornado was especially photogenic, one for the history books. Another tornado occurred in the vicinity of the Antelope Ridge subdivision on the same day.
An isolated supercell thunderstorm developed in central Albany County, Wyoming about 13 km (8 miles) north of Laramie during the late afternoon on June 6, 2018. The storm initially produced a tornado 5 – 6.5 km (3 to 4 miles) west of Highway 30.
The tornado tracked east across Highway 30 and intensified rapidly moving through mainly open fields. Numerous wooden power poles were snapped along County Road 121, along with several galvanized steel utility poles which were bent 90 degrees at the base.
Grass was scoured out of the ground in a wide swath approximately 500 m (547 yards) in width near the intersection of County Road 121 and Cattle Drive. This is consistent with an EF-3 tornado.
The tornado was observed to continue east up into the Laramie Range near King Mountain Road for a period of over 45 minutes.
A satellite tornado developed 3.2 km (2 miles) to the south of the parent tornado. This tornado damaged treetops and caused significant structural damage to a well-built attached garage, which collapsed as it lifted off the foundation and shifted to the east. The damage to the garage was consistent with an EF-2 tornado.
In addition, several nearby structures had minor damage to siding and shingles. The tornado was observed moving through the Antelope Ridge Loop subdivision, 10 km (6 miles) north of Laramie, and into open country.
