Wow, all I can say is WOW! What an amazing supercell this day produced! Great shear, good moisture and instability, and lift along a boundary and mountains would provide all that was needed to get the best structured supercell of 2021 to form. After hanging out in Havre, MT waiting for a storm to get going, we finally got our wish. Due to the late setting sun in Montana in June, we had several hours to watch this storm ramp up and become a jaw dropper! The one unfortunate thing that occurred were the poor road networks in Montana. We were able to stay with this mothership supercell for a few hours east of Lodgepole and enjoy the treat! Incredible structure and the beautiful countryside in Montana made this day one of my favorite for 2021! Please take time and enjoy the photos of this stunning storm!
