There was a small pop up cell that came through the area yesterday causing a Severe Thunderstorm Warning for Several Counties in Southern Indiana. In Vanderburgh County the sirens are set off for Severe Thunderstorm Warnings so they were set off for this. The sirens went off the first time while I was at my grandmas with no camera to record and they went off the second time (the one recoderd) when I was about to pull into my driveway. I looked up to see my dad outside with the camera recording the sky and the sirens. Sp here it is. Sirens heard are 1 - Sentry 7V8 and 2/3 - Sentry 15V1T's I would like to thank dear old dad for this one! Enjoy!!!
