The husband-and-wife team of Amos and Megan Dodson, both meteorologists at the northern Indiana office of the National Weather Service (NWS), conducted the annual SKYWARN storm spotter training Feb. 16 at the Public Safety Academy of Northeast Indiana.

The content of the training didn’t change much from last year’s presentation. It focused on the differences between truly threatening weather phenomena and scary-looking, but harmless (and unreportable) conditions.

Here are some highlights:

  • Spotter reports add credibility. When the NWS issues a warning that includes a reference to a spotter report, members of the general public are more likely to take action than when the warning does not include a spotter reference.
  • Don’t wait for activation. Although our NWS office issues hazardous weather outlooks that indicate whether spotter activation is likely, the office does not “activate” or “deploy” spotters. It welcomes spotters to make reports anytime they see anything reportable.
  • Clouds with ragged edges aren’t spinning. Scary-looking SCUD clouds that are shaped like funnel clouds generate a lot of well-intended but false reports from untrained observers. True funnel clouds and tornadoes spin, giving them sharper, smoother edges.
  • When unsure, send a photo. NWS encourages spotters who see something that might be reportable (like a possible wall cloud or funnel cloud), to photograph it and send the photo via Twitter (@NWSIWX) or the NWS office’s Facebook page. The office monitors both social networks closely during severe weather events.
  • T.E.L. NWS. When spotters make reports, they should provide the Time of the observation, a description of the Event, and the Location of the event. The actual time of day is more valuable than “right now” or “two minutes ago.” And because the local NWS office does not issue spotter credentials, formatting reports in that specific order is one way spotters can demonstrate they attended the training.
  • Thunderstorms come here to die! Spotters provide a valuable service to their communities even if they don’t see anything reportable. And climatology data shows that spotters in Indiana are about half as likely to see something as are spotters in Illinois. Megan Dodson shared that this leads meteorologists to joke that Indiana is where thunderstorms come to die.

Mysteriously, far fewer people attended the training than registered for it, even though weather did not hinder travel that night. Those in attendance, however, included TV meteorologist Hannah Strong, who indicated that the presentation included information not provided in meteorology school.

People who missed the training can get via the Web most of the information they need to be effective spotters. Two options include
