I took these pictures near 51st/I-44 and Lewis in Tulsa, OK on March 15, 2015. I heard the sirens go off and I grabbed my camera and ran outside. This cell touched down about 20 minutes before I took this picture in Sand Springs, causing one fatality. The cell was just east of downtown at this point, about 5 miles to the north, so I wasn't in any danger from it. The skies can look wicked around here.
