This high-based and elevated thunderstorm was part of a short line that fired in Wyoming, where the Plains meet the mountains. The line rumbled to the southeast, fueling itself on residual moisture and instability found above an outflow pool from earlier, dissipated storms. The electrical display it offered was spectacular, as often is the case for any twilight to nocturnal storms on the High Plains. An invisible step leader for this stroke parted ways outward and downward after exiting cloud base. It’s not hard to guess which one would contact the ground charge first!
