Supercells were the expected mode of convection, but storms quickly evolved into a small complex. I raced ahead of a developing bow echo and was quite pleased with the linear structure. As the chase progressed, the structure continued to get better as it raced to the east at 40 mph.
A monstrous HP supercell rolled into the western sections of Sioux Falls, SD just before midnight on 24 June 2003. This storm earlier produced numerous tornadoes near the Centerville, SD region. A weak tornado was spawned near the time of the photo on the north side of the updraft, not visible from our location.
This storm earlier produced two tornadoes and then became an outflow dominant beast. This shelf cloud moved east at nearly 60 mph. We were overtaken by the line with a necessary gas stop. The vehicle behind mine lost the back window from flying rocks.
The tail-end-charlie shelf cloud near sunset became the highlight of the day. There were reports of baseball size hail within the core. We were on the road for 27 hours straight; something that could've only been feasible in my younger days.
An ominous looking severe storm complete with a dust-filled shelf cloud scraping the horizon. We let the storm impact us while underneath a gas station canopy. Nearly a foot deep of hail was the end result.
