As another line of storms began to move through the state that afternoon, we set up on Hwy. 64 between Conway and Beebe and watched an impressive gust front/shelf cloud move through, kick up large amounts of dust and produce a gustnado. The gustnado was a decent size and had some strong inflow associated with it, but it was short-lived and dissipated after a few seconds.
At the time, The gustnado and shelf cloud were some of the most impressive weather phenomena I had seen while chasing.
