This website’s weather information is made possible by the world-class work, technology, and data of the U.S. National Oceanic and Atmospheric Administration (NOAA)
Who are we?
TwisterData.com was developed and launched in 2008 by storm chasers and meteorologists David Demko and Donald Giuliano. Don and Dave share a deep passion for weather
and meteorology, and began chasing storms together at the University of Oklahoma in 2000.
Why?
As avid storm chasers and weather watchers, we make extensive use of internet weather data websites. Our goal was to create a website that gets out of the
way of the user, allowing them to focus on the data. We hope we have succeeded and plan on continually improving and enhancing the website's user
experience. To learn more about the website's features, please read through our brief tutorial.
Will you charge for data?
We have no plans to charge for basic weather model output data and graphics. Raw scientific data presented on this website is sourced and made freely available to all from NOAA/NWS.
