Event narrative (NOAA)
This was the first and strongest tornado of the day. It developed west southwest of Lake City and produced tree and power line damage. The tornado moved into and across the southern portion of Lake City. Imagery from UAV's and chasers show that the tornado was multi-vortex as it passed through the city. Up to EF2 damage occurred as it passed through town. As the tornado moved east of the town, it began to consolidate into a larger funnel and strengthen. It passed through a farmstead producing considerable damage to the farmhouse and out buildings with EF3 damage noted on the house. The tornado continued for a few more miles and impacted a confinement facility before lifting to the northwest of Lohrville. Fortunately, no injuries or deaths occurred with this tornado.
