This tornado was witnessed, photographed, and/or videoed by several people.  The start time/location is estimated by CHIVO radar as no eye witnesses saw it until 6:48 or 6:49 PM. However, the radar signature shows dust/dirt and a decent circulation that is continuous throughout the start/end times.  This tornado was filmed by a farmer in her tractor from 6:50-6:53, and was at least a mile to her northeast.  It was ongoing when she started filming. The tornado was also photographed and filmed from 6:52 – 6:59 PM, roughly, by a chaser on CO-392.  At nearly the same time, a resident on WCR66 and east of WCR 47 videoed this tornado just to the NE and then N of her farm.  The chaser on CO-392 captured it crossing CO-392 and hitting a barn just north of CO-392, at 6:57 PM.  CHIVO radar shows a significant circulation and dust/dirt throughout the reported time window of this tornado, continuing north of CO-392. This tornado was also photographed from 15 miles east of Loveland at 6:54 PM, showing two tornadoes on the ground at the same time, this one and tornado #3 to the northwest.  Damage to the farm north of CO-392 was minor and consisted seriously damaging an aluminum shed, consistent with  high end EF-0 with winds 83 mph, and a Degree of Damage of 3.  The video shows the shed getting hit and debris scattered to the northwest.  The tornado dissipated somewhere around WCR70/45 based on radar.  An eyewitness on WCR45 north of WCR70 mentioned seeing a tornado prior to his filming a tornado at 7:14 PM (which was tornado #5).  We presume tornado #4 is the tornado he witnessed.   CHIVO has it dissipating around 7:01 PM.
