If a tornado watch were issued, would you know exactly what to look for in terms of cloud structure to spot a wall cloud or even a funnel?
Pretty much everyone who knows me knows that I am a National Weather Service-trained severe weather spotter. Before I took my first training class on March 3, 2008, I was pretty sure I knew what a wall cloud looked like. I soon learned, though, that I was wrong. What I thought was a wall cloud—or an isolated lowering of the cloud base—was actually a shelf cloud.
Now I know what to watch for. I can tell if an approaching storm could spawn a tornado, and I even put that training to use a couple of years ago. I watched from my old apartment as a strong storm formed over Lake Michigan. .
That's what a storm spotter does. According to the National Weather Service Office in Chicago, their meteorologists monitor Doppler Weather Radar but "also depend on real-time reports from trained spotters to know exactly what is occurring on the ground under a storm.
"The NWS trains people to identify severe storms and tornadoes and report them via organized communications networks," according to NWS Chicago Office website. "A storm spotter is a volunteer or paid county or municipal employee who is spotting as a community service."
At a typical class, which lasts about an hour and a half to two hours, students learn the basics from a NWS meteorologist and watch videos to help identify cloud structure and other severe weather features. Students also receive the Basic Spotters' Field Guide booklet. The classes are free.
