June 24, 2010 Bismark, North Dakota Tornado Warned Supercell

June 24th was a surprise day for me. Fairly poor low level shear, little forcing, no decent boundaries, and only meager moisture had me concerned about the quality of a storm today. I wasn’t even sure a storm would form. However along a confluence line, towering cu went up late afternoon, and a gorgeous supercell formed. This storm refused to quit and even after we left it, it was still severe and even briefly tornado warned. While we were chasing it up until dark it had been tornado warned twice with one very convincing funnel reaching 3/4 of the way to the ground. However, I can not confirm a touchdown. Nonetheless, it was a very pretty classic supercell most of its life cycle.
