Surprise! While fueling up at a south Tucson gas station, I happened to glance at a nearby, ragged, high thunderstorm base through a slot between the awning and store building. Lo and behold: a nub funnel cloud appeared—rotating as a true funnel must, albeit slowly. The cyclonic, non-supercell funnel gradually lengthened into a cone and persisted for a few minutes. That was just long enough to finish fueling, drive around back where I could see better beneath, and shoot, before the small, accompanying cloud-base circulation wrapped enough rain and outflow from the adjacent core to kill the funnel. No evidence ever appeared underneath of debris, nor was any damage reported in the area. If there was a ground circulation, it was too weak to call a tornado. Nonetheless, I reported this to the local NWS, for the record. Eyes to the sky!
