David Huffman

President, Weather Radar Warning System, Inc.

“I was born in Arlington to Lloyd and Sue Huffman (of Corsicana and Sulphur Springs, TX, respectively) in 1969 while my father was attending the University of North Texas. Our family returned to Corsicana in 1975 when I was about 5 years old, whereupon my parents started our family business, Huffman Communications. I graduated from Corsicana High School in 1988, received a BS in Industrial Engineering and a BS in Computer Science from Texas A&M University in 1995, and afterwards returned to Corsicana to work in the family business, where I have been been ever since doing two-way radio and microwave communications work for emergency responders and public utilities.

The Corsicana Radar has always been a part of my life. I was a child when my father started the project in 1975, and I remember riding the elevator to the topmost floor of Corsicana Memorial Hospital where the original radar was located. I didn’t understand what the radar was until much later, but I thought the antenna and radar screens were pretty cool.

I began working on the radar as a volunteer when I helped my father build the radar’s first dome out of fiberglass during my freshman year in high school. This dome lasted about 10 years, until straight-line winds blew it off the derrick in 1996, whereupon it was replaced by the space-frame dome we have today.

When I returned to Corsicana after college, I began working on the third generation of signal processor, control and display system for the radar. This system is still currently in use at CORAD, and was also used for many years by several television stations including KWTV in Oklahoma City, KOTV in Tulsa, KXAS in Dallas and KXII in Sherman, TX. I am currently working on the 4th generation signal processor and display system and hope to have it operational by spring of 2024.

I volunteer at CORAD because I love our community and enjoy the engineering challenges of radar system development.”

I have been a volunteer with CORAD since spring of 2022. I am currently a senior at Corsicana High School and hope to pursue a PhD in Meteorology and Atmospheric Studies at the University of Oklahoma. I spend a lot of time outside the radar keeping up with forecasts and managing social media, as well as storm spotting/chasing during severe weather.
I am very passionate about the art of photography and videography, and of course meteorology. I feel that being able to go out and capture the beauty of nature and study it when it’s at it’s most violent is a truly enlightening and humbling experience, and being able to share this with the people around me makes it extremely special for me. CORAD is a major learning experience for me, and I am extremely thankful for the opportunity to work with this organization!
