Johns grew up in Terhune, Indiana, where his father ran the general store. His childhood included observing weather and developing his intense interest in meteorology. He attended Purdue University earning a B.S (1962), then earning an M.S in meteorology from the University of Oklahoma (OU; 1965).

Afterward, he returned to his meteorologist job with the USWB, taking a position at the forecast office in Kansas City, Missouri. Johns remained in this position until May 1971, when he transferred into the National Severe Storms Forecast Center (NSSFC).

Johns retired from the SPC in 2001.

Retirement After he retired in 2001, Johns started working on a project reanalyzing the Tri-State Tornado. Johns died on October 26, 2020.

Research Johns furthered forecasting techniques and developed the modern conceptualization of the derecho following landmark work on "northwest flow" severe weather patterns. Johns also issued the first enhanced wording "Particularly Dangerous Situation" (PDS) for tornado watches during the April 2–3, 1982 tornado outbreak. 2001 Silver Medal (Joint Organization Award) – “For providing the citizens of Alabama life-saving tornado watch and warning information during the tornado outbreak of December 16, 2000.” 2001 Dr. T.
