June 4th Montana Stunning Supercell

June 4th took us to central Montana. Great flow with a shortwave moving into the Pacific Northwest would help set the stage for storm formation. Ample shear, good instability and moisture, and convergence along the mountains southwest of Great Falls would allow storms for form by late afternoon. A tornado watch was issued for the area as storms formed and intensified near Helena. One supercell moved towards Great Falls and became quite photogenic as it moved northeast towards Ft Benson. This storm became tornado warned and also produced baseball sized hail. One of the prettiest supercells of the year!
