A long-lived supercell thunderstorm produced widespread wind and hail damage, and several tornadoes as it tracked east/northeast across eastern Colorado. The first tornado was reported in northeastern Adams County. Then two more brief tornado touchdowns occurred as the storm moved east to near Akron. No damage was reported from the first three tornadoes. A stronger EF-1 tornado (86-110 mph winds) developed as the storm tracked east to near Platner. Significant damage occurred to a pole shed, where the tornado lifted the entire shed and destroyed it.  Debris from this shed traveled around 1 mile to the southeast where the tornado lifted. Only minor structural damage occurred elsewhere on the farm northeast of Platner. Two families in a single-family home, totaling three adults and four children, were displaced by the damage. The Red Cross provided temporary lodging, food and clothing.
The supercell formed over south Denver and tracked east/northeast across northeast Adams, southern Morgan and northern Washington Counties; the storm continued to produce severe weather as into moved into Yuma County. The length of the path through Northeast Colorado was approximately 121 miles from southeast Denver to the Yuma County line. The storm produced hail up to 1.5 inches in diameter in southeast Denver. As it moved across northeast Adams County, several power poles were sheared off at the base by straight-line winds, southwest of Leader. Across Morgan County, hail up to 1.5 inches in diameter was observed. The damage path became more extensive as the storm tracked across northern Washington County. Wind driven hail up to 1.75 inches was reported with extensive damage from around Akron east to the Yuma County line. Extensive hail damage included broken windows to cars and homes. Several power poles were snapped near Otis. In all, up to 10 structures were damaged or destroyed from near Platner to the Yuma County line. While some of the damage was tornadic, most of the damage was caused by straight-line winds.  In addition, a severe thunderstorm produced large hail in Jefferson County.
