Social media provides an excellent addition to our weather presentations. Wednesday’s super cell threw down 2 inches of rain in less than an hour, initiating flash flooding. Our weather watchers responded with shots of the storm’s impact. As noted in a previous column, photo technology increased after the Civil War. On Aug. 28, 1884, F.N. Robinson, in the Dakota Territory, captured what was thought to be the first photo of a tornado. Weatherwise Magazine published the photo, including a thunderstorm cloud with two funnels. A debris cloud is visible; it was part of a storm that killed six with property damage and loss of livestock. Updated research found that four months earlier, on April 26, in Garnett, Kan., A.A. Adams photographed another tornado, officially becoming the first twister photo. Fastcast: Clearing.
