With severe weather in the forecast, I headed downstate to do some storm chasing. This cell formed over the Laramie Mountains before pushing east onto the High Plains. At first it took it's time maturing. But just before 4PM it transformed from an ok looking storm into this in only 10 minutes. As the storm moved into a better wind shear environment, it turned into a mothership supercell displaying very impressive structure. I was mesmerized watching it roll across the Nebraska stateline outside of La Grange. Despite the ominous and otherworldly look, the storm wasn't severe at this time. As it passed over me it brought small hail and blowing dust with lots of tumbleweeds.
