July 12th Southeast North Dakota Tornado Warned Supercell
What a finish to a day that looked pretty doomed. Cloud cover all day kept good insulation from occurring and thus reducing instability. Just south of the North Dakota border, skies were clearer, but shear was weaker. Nonetheless, a supercell, nearly tornadic, formed near Cayuga, North Dakota and became a very nice storm! It was quite electrified and also produced copious amounts of large hail. We watched it form from a towering cu all the way through its decaying stage. What a treat!
