As we were driving south in Pueblo County in southern Colorado we watched with interest as quite the May storm was brewing ahead. We watched as this Nimbostratus storm cloud began to strengthen and show some signs of central rotation as it gained energy. The massive cloud was on the move and had already hidden much of the Wet Mountains in the background. The mountains to the right are gone and soon the southernmost portion of the range will disappear as well as the storm rumbles its way south. The main illumination in the image is from behind and through the cloud bringing out the striking color and texture as the light comes through the cloud as well as bounces off the ground thus also illuminating for the bottom of the storm cloud.
