A mosaic of the severe thunderstorm just outside of Alzada, Montana this last Saturday evening (July 5, 2025). Final image consists of 9 portrait oriented frames shot through a 24mm lens. The deep water column of the storm, and the sun's angle yield a palette of vivid greens and blues in the storm's clouds. Extremely heavy rainfall accompanied this storm, nickel sized (2.25cm approx) hail at my location, along with many recorded wind gusts of 70+ mph through southeast Montana and reaching into extreme northeast Wyoming and into western South Dakota.
