About lightning in Wyoming
Wyoming’s thunderstorms build over the high plains and Rockies through the summer, when afternoon heating lifts air along the terrain into storms with frequent lightning and hail. Many are dry storms whose lightning starts wildfires across the open range. Activity runs June through August. Because dry lightning can strike far from any rain, the live distance to the nearest flash and whether it is approaching are the numbers that matter.
