SPC Storm Reports<\/a><\/p>\n

I was back in Denver, and ready to start Tour 6 with Rook and Steve P. \u00a0Tour 5 had had some success in Montana and the Northern Plains, but the overall pattern for the first two weeks of June continued to be on the dismal side for chasers on the Plains. \u00a0On this chase day, there was a risk of tornadoes around the Minnesota\/Dakotas border area, but that would not be reachable this day from Denver. \u00a0I saw some potential for a supercell in western South Dakota, so we made our way northward after the guest orientation. \u00a0SPC painted western SD and adjacent areas with a marginal risk of severe.<\/p>\n

We reached southwestern SD via Lusk and Sundance. \u00a0By the time we hit I-90, near the WY\/SD border, we had in our view a growing cumulonimbus cloud well to our NNE. \u00a0The developing storm was likely not far from Redig, between Belle Fourche and Buffalo. \u00a0That is what we wanted, and it was surrounded by beautiful blue skies! \u00a0And, not surprisingly, its updraft started to rotate, and the storm propagated to the right — towards the east-southeast. \u00a0That gave us a good chance of catching it relatively quickly.<\/p>\n

We stopped a little north of Belle Fourche for pictures. \u00a0The storm was west of Castle Rock, perhaps 30 miles distant, and to our NNE. \u00a0The updraft was impressive, and a shallow lowered area was apparent on the updraft base. \u00a0In order to get close and to be in the right position to view the storm base, we headed east to Newell and then north. \u00a0The wall cloud was impressive to our north as we made our way east to Newell. \u00a0This may have been the period when the supercell was closest to producing a tornado. \u00a0The fourth image below shows some scud near the ground behind Belle Fourche Reservoir.<\/p>\n

As we neared, north of Newell along Route 79, the wall cloud was less pronounced, there was more rain from the base, and the updraft was getting a nice, round sculpted shape. \u00a0The supercell moved over 79 to our north, and baseball-sized hail was noted and reported by a police officer. \u00a0It was at about this stage, though, that the updraft tower became more and more sheared over. \u00a0It may have been that the loss of daytime heating was diminishing the instability available for this surface-based storm. \u00a0We stayed with the slowly shrinking updraft base to the east of Newell for perhaps 10 or 15 miles, along old U.S. Highway 212, and then it was back to Belle Fourche for the night. \u00a0Interestingly, this storm resulted in the largest hail report for the day in the country. \u00a0Well, the actual report itself was the same size as all of the others, but the hail size given was the greatest.<\/p>\n
