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.
About 1 hour after the storm forms near Bismark, ND, it now appears to be a supercell.
Storm continues to get better organized with a well formed rotating wall cloud now.
Fairly stout funnel forms as it is now tornado warned.
Funnel quickly disippates, but the structure continues to be very nice.
Absolutely beautiful supercell now! Nice rotating soda can!
Fantastic vault and structure. Still severe for baseball sized hail.
