Wednesday afternoon, several showers and storms moved through the region. In general, these storms produced winds less than 40 mph as well as briefly heavy rains. One storm however was noticed by a couple of spotters, Jonathon Durall and Dustin Knight, as having a weak gustnado. They took the following photos and brief video of the storm, which occurred in southwest Grayson county in Kentucky yesterday afternoon a little after 4 PM CDT.

After the storm, they went to the area where the gustnado passed and did not see any damage. Most gustnadoes produce a small area of stronger winds, and in this case it likely only produced winds of 40-45 mph. The National Weather Service Doppler Radar imagery, seen below, from the approximate time of the gustnado showed only a weak rotation.
