May 5th brought deep moisture into central Texas, along with moderate instability and decent wind shear. Storms formed west of Hamilton and moved southeast. One storm right turned as it started spinning and moved all the way to the north side of Austin before weakening. It had good structure, monster sized hail and was very electrified. It produced stunning mammatus clouds as well. The rotation buried well back in the core was very strong, and it may have produced a tornado that would have been not visible due to the heavy precipitation. Nonetheless, it was a treat to watch and enjoy!
