Henry Cramer
Henry was born and raised in Stickney, South Dakota, and later moved to Mitchell. After a year in Olathe, Kansas, he returned to South Dakota in 2006 and settled in Harrisburg, where he lives today. Growing up in the heart of the Great Plains exposed him early to the power and beauty of severe weather.
The 2003 Manchester, South Dakota, tornado was the event that ignited his passion. Watching the coverage and learning about the tornado's power and impact pushed him to learn everything he could about severe storms, forecasting, and atmospheric science, almost entirely self-taught.
From 2004 through 2018, Henry stepped away from chasing to raise a family, pursue music, and build a career in the financial services industry. Those years sharpened the leadership, communication, and organizational skills he uses today. In 2018, his passion returned stronger than ever, and he got back on the road.
Then came the 2019 tornadoes that struck parts of Sioux Falls. Henry watched his youngest son be terrified and felt helpless as a father, and he realized other families were feeling the same way. That moment led him to start SD Weather Enthusiast, which grew into 605 Chaser and, in 2026, became 605 Chaser LLC. Today the operation covers a five-state territory and reaches more than 25,000 followers across Facebook, YouTube, and TikTok.
As President, Henry is the team's lead forecaster and oversees operations, strategy, livestream production, content, technology, and community outreach. He also builds much of the team's custom tooling, from live broadcast overlays and real-time mesoscale analysis tools to the Tornado Target Finder and ChaserOS. His day job as a dialer operations analyst, built on data analysis, operational planning, and technology, carries directly into forecasting and running a field team. He is Spotter Network certified.
Education and public safety are at the center of Henry's mission. He has given severe weather presentations at local schools, including one featuring a hands-on tornado demonstration model he built with his son to show how the ingredients for tornado formation come together. His goal is to make weather information accessible, reduce fear through education, and help people make informed decisions before and during severe weather.
In the field, Henry believes the biggest challenge is balancing safety, responsible reporting, and growing road congestion during major events. He relies on situational awareness and multiple data sources, and he holds firm to one rule: safety always comes before footage. His favorite part of the job is supercells, analyzing the setup days in advance and then watching it unfold in real time.
Outside of weather, many people are surprised to learn that Henry sang professionally and released a music album in 2004. Music, performance, and storytelling still shape how he connects with audiences today.
