June 27th Amidon, North Dakota Tornado Warned Supercell

June 27th had a lot going for it. An approaching shortwave trough, an outflow boundary along with a dryline, as well as decent moisture with dewpoints in the 60s and moderate CAPE around 2500 j/kg would set the stage for severe weather in Montana, North Dakota and South Dakota. We originally targeted the area around Buffalo, South Dakota, but as moisture mixed out, we knew we’d have to venture a bit further north into southwest North Dakota. A supercell formed near Beach and became tornado warned. An hour later another supercell formed northwest of Amidon and also became tornado warned. We pushed north to get in position to watch it and as we did a couple of weak funnels formed under it and were reported to the NWS. The storm was anchored along a boundary and slowly back built. Numerous times there were rotating lowerings under the southwest portion of the updraft, as golfball sized hail fell from the vault region. Eventually the cell turned southeast and moved off the boundary. However, it moved into more stable air and slowly weakened but not before becoming tornado warned one last time! We stayed with it over beautiful canola fields and stopped for some photography. A fun day, and some amazing scenery!!!
