A funnel cloud prompted a brief tornado warning in Cheyenne on Wednesday.
The National Weather Service sounded the alarm at about 2 p.m., soon after the funnel dropped down from a small thunderstorm in the high country west of town.
 
Minutes later, the funnel dissipated without touching down - though not before several people snapped photos of the twister and posted the images online.
 
The storm caused nothing worse than some light rain in the capital city. Sheriff's officials say no damage was reported.
