Video Screen Captures of May 2 Hills Iowa Tornadic Storm

This image and all the images below are all video screen captures from 7:47-7:52 pm CDT, Wednesday, May 2, 2018, taken from the Casey's General Store in Hills, Iowa and looking northwest. They show the approaching tornadic storm which prompted sirens to sound in the town of Hills. The lower resolution screen captures and growing darkness forced these grainy images, but their dramatic appearance overshadows the noise. Nikon D7200 DSLR camera.
