NOAA and 1974 Tornado Outbreak

1974 Tornado Eyewitness Account
By Warren Sunkel, Regional Applied Technical Services Meteorologist
Meteorological Services Division
National Weather Service Central Region Headquarters

In 1974, I was the Meteorologist in Charge of the National Weather Service Meteorological Observatory in Marseilles, Il. On April 3, I worked the midnight to 8 a.m. radar shift. Between 6 a.m. and 7 a.m., I observed a squall line moving east through the St. Louis metropolitan area.

At 8 a.m. I was relieved by David Brandon, now Hydrologist in Charge of the Colorado Basin River Forecast Center. I drove home to my apartment in the next county to the east. About 9:30 a.m. my neighbor came downstairs and said that a tornado warning had been issued for our county. We watched for it, but the storm was already east of our location. This tornado was eventually classified as the first tornado of the Super Outbreak. The warning was based on a hook echo observed by David Brandon on the WSR-57 radar at Marseilles.

I returned to work for the midnight shift the following morning. Because there were no echoes to report in my area of responsibility, I was listening to a Chicago station on AM radio. Every hour on the hour the network news would chime in with an updated death toll from the Super Outbreak. It wasn't until later that day that I realized the extent of the disaster.

The WSR-57 radar network was the primary tornado warning tool of the era. It was supplemented by older, less-powerful WSR-1 and WSR-3 radars known as "gap fillers." Volunteer spotters also played a vital role in the tornado warning process. Warnings were typed by hand on a Model 28ASR teletypewriter and distributed over the NOAA Weather Wire. NOAA Weather Radios were confined to large metropolitan areas. In general, there were only two or three transmitters per state. The Super Outbreak of 1974 prompted an initiative to greatly increase the number of NOAA Weather Radio transmitters during the middle 1970s.
