May 21st was the first day in a period that would be the best of 2016. This day featured a triple point over western Kansas, as well as good shear, strong instability and decent moisture. Storms appeared they would form on the HP side of thing and they sure did. The triple point and warm front lit up like crazy mid afternoon, and the tail end storm would become the storm of the day. Anchored at the triple point, this supercell would cycle many times and each time get prettier and prettier. It produced a couple weak, short lived tornadoes in its lifetime, but the story of the day was the storm’s structure. It was a sculpted twisting, turning supercell, easily the prettiest of the year. Each updraft that formed at the triple point would be ingested into the main storm’s updraft, proving a fresh poof of warm moist air for the cell to feed on. Helicity was quite strong in this beast and I was actually surprised it did not produce a significant tornado.
By mid evening, the storm was running out of available instability, and it started to weaken. Right at sunset it was quite pretty, with a liberty bell appearance and tons of lightning. Finally just after dark it died off, and the skies calmed for the night. This would be short lived as the next day proved to be quite volatile a bit further south in Texas.
