We were in a restaurant and there was heavy rain and lighting all around. We knew there were tornado warnings for the area, and the news behind the bar said that one had been spotted near us. I pulled this out, got the current radar map and was able to see where the hot spot of the storm was, we went do it (within a reasonable distance, just close enough to see) and we were able to see a fully formed, touched down tornado for a few mins. It was in a field, no one was hurt. But we would have missed it otherwise. Thanks!
