This storm was classified as a gustnado. A gustnado is similar to a tornado in the fact that it rotates, but it’s direction is horizontal rather than a vertical like an actual tornado.
The average gustnado lasts a few seconds to a few minutes, although there can be several generations and simultaneous swarms. Most have the winds of an F0 or F1 tornado, and are commonly mistaken for tornadoes. However, unlike tornadoes, the rotating column of air in a gustnado usually does not extend all the way to the base of the thundercloud. Gustnadoes actually have more in common with whirlwinds (which include dust devils, whirlwinds that form due to superheated surface layers and stretched vorticity, most commonly on sunny, warm days with light winds).
